Why You’ll Love This Cheesy Sausage Breakfast Casserole (A Crowd-Pleasing Favorite)

This recipe consistently earns rave reviews, not just because it’s easy, but because the combination of textures and flavors is perfectly balanced, making it far superior to your average scrambled eggs or simple slice of toast. Here are several reasons why this will quickly become a fixture in your recipe rotation.
Unbeatable Flavor Combination
The foundation of this dish is the dynamic pairing of salty, seasoned breakfast sausage and sharp cheddar cheese. We recommend using a good quality, sharp cheddar, as its bold flavor cuts through the richness of the sausage and dairy, preventing the dish from tasting flat. The mild hint of dry mustard and garlic powder, while optional, elevates the egg custard, adding a subtle warmth and complexity that truly distinguishes this casserole. Every bite delivers that classic, hearty breakfast flavor profile a truly comforting experience.
The Magic of Make-Ahead Meal Prep
The single greatest benefit of the Cheesy Sausage Breakfast Casserole is its inherent design for make-ahead convenience. You prepare the entire dish sausage cooking, layering, and soaking the day before. This means zero morning fuss. For hosts, this is a game-changer, allowing you to focus on table settings or other aspects of your brunch without being tied to the stove.

Many homemade breakfast casseroles suffer from either a soggy bottom or a dry, unevenly cooked interior. This recipe specifically addresses that common failure point. By allowing the bread cubes to soak overnight (the crucial Step 7), they transform into a soft, sponge-like base that perfectly absorbs the egg custard. When baked, the result is a fluffy, light, and custardy interior that holds together, topped with a crisp, golden layer of melted cheese and browned sausage. It’s the perfect harmony of textures in every forkful.

Essential Ingredients for the Perfect Breakfast Casserole (Ingredients and Necessary Utensils)
Success in making this delicious Cheesy Sausage Breakfast Casserole starts with selecting high-quality ingredients and having the right tools on hand. The following section breaks down the precise measurements and provides insight into why certain ingredients work best.
Detailed Ingredient List
To prepare your savory, cheesy breakfast bake, you will need the following items. We recommend gathering all your ingredients before starting the preparation process (a technique known as mise en place) to ensure a smooth assembly.
The Core Components:
- 1 pound bulk breakfast sausage (mild or spicy): The star protein. Use high-quality bulk sausage for the best flavor. If you prefer a richer flavor, opt for spicy; for wider appeal, mild works well.
- 6 slices day-old bread: Crucial for texture. Use sturdy bread like Texas toast, brioche, or sourdough. It should be diced into 1-inch cubes (about 4 cups total). Day-old bread is slightly drier and absorbs the custard better.
- 2 cups shredded sharp cheddar cheese: Sharp cheddar is essential for that pronounced cheesy flavor. Avoid pre-shredded cheese if possible; freshly shredded cheese melts smoother and contains less anti-caking starch.
The Custard Base:
- 10 large eggs: These provide the structure and protein base for the casserole.
- 2 cups whole milk: Whole milk offers the best richness. For an extra decadent casserole, substitute half-and-half or heavy cream.
Seasonings and Flavor Boosters:
- 1 teaspoon salt: Essential for balancing the richness.
- 1/2 teaspoon black pepper: For a slight kick and aromatic lift.
- 1 teaspoon dry mustard powder (optional, but recommended): This ingredient doesn’t make the casserole taste like mustard; instead, it works as a secret ingredient, intensifying the savory and cheesy notes.
- 1/4 teaspoon garlic powder (optional): Adds a subtle, savory depth that complements the sausage.
Preparation Essentials:
- Cooking spray or butter: For greasing the standard 9×13 inch baking dish.
Recommended Tools and Utensils for Recipe Success
While this recipe is straightforward, having the correct tools makes the preparation, especially the overnight chilling and subsequent baking, significantly easier.
Essential Equipment:
9×13 Inch Baking Dish
This standard size is key for ensuring proper thickness and cooking time for the Cheesy Sausage Breakfast Casserole. A ceramic or glass dish works well, as it retains heat evenly.
Large Skillet
Needed to cook and properly drain the breakfast sausage. Ensure it’s large enough to handle the full pound of meat without crowding.
Large Mixing Bowl and Whisk
Required for thoroughly combining the 10 eggs and the 2 cups of milk, along with all the seasonings, creating the perfect egg custard. Vigorous whisking is crucial to properly aerate the eggs.
Spatula or Wooden Spoon
Necessary for breaking up the sausage while cooking and pressing down the casserole layers before chilling.
Plastic Wrap or Foil
Crucial for tightly covering the Cheesy Sausage Breakfast Casserole during the minimum 3-hour (ideally 8-12 hour) refrigeration period. A tight seal prevents the bread from drying out.
Gathering these items ensures you are ready to tackle this easy yet impressive breakfast bake.
Step-by-Step Guide to Making the Best Cheesy Sausage Breakfast Casserole
Making this incredible Cheesy Sausage Breakfast Casserole is simple, but the timing of certain steps especially the resting period is vital for achieving that perfect custardy texture. Follow these detailed steps for guaranteed success.
Phase 1: Preparation (The Night Before)
- Prepare the Pan: Grease a standard 9×13 inch baking dish thoroughly with cooking spray or butter. Set aside. Generous greasing prevents sticking, which is especially important for a hearty, baked dish like this.
- Cook the Sausage: Place the bulk breakfast sausage in a large skillet over medium-high heat. Cook, breaking it up with a spoon, until it is completely browned and cooked through. This usually takes 7-10 minutes. Crucially, drain off any excess grease immediately. Excess fat can make the final casserole greasy. Set the sausage aside to cool slightly.
- Assemble the Base Layers: Scatter the 1-inch cubed bread evenly across the bottom of the prepared 9×13 inch baking dish. Try to make a relatively flat, consistent layer. Sprinkle the cooked and drained sausage evenly over the layer of bread cubes.
- Add the Cheese: Evenly sprinkle the 2 cups of shredded sharp cheddar cheese over the sausage and bread layers. Ensure the cheese is distributed edge-to-edge for optimal melting coverage.
- Prepare the Egg Custard: In a large bowl, whisk the 10 large eggs vigorously until they are well combined and slightly frothy. Pour in the 2 cups of milk (or half-and-half). Add the salt, black pepper, dry mustard powder (if using), and garlic powder (if using). Continue whisking the mixture until all the seasonings are thoroughly incorporated and the custard is uniform.
- Saturate the Casserole: Slowly and evenly pour the egg and milk mixture over the bread, sausage, and cheese layers in the baking dish. Start pouring near the edges and work your way in. This slow pour helps the bread begin soaking evenly. Press down gently on the top layer with a spatula or the back of a spoon to help the bread absorb the liquid. Ensure every piece of bread is moistened.
- Chill and Soak (Crucial Step): Cover the baking dish tightly with plastic wrap or aluminum foil. Refrigerate the casserole for a minimum of 3 hours, or ideally, overnight (8 to 12 hours). Do not skip this step! This allows the bread to fully soak up the egg mixture, preventing a dry casserole and resulting in that desirable puffy, custardy texture.
Phase 2: Baking and Serving (The Next Morning)
- Preheat the Oven: About 30 minutes before you plan to bake, remove the Cheesy Sausage Breakfast Casserole from the refrigerator to allow it to come slightly closer to room temperature. This helps the casserole bake more evenly. Preheat your oven to 350°F (175°C).
- Bake the Casserole: Remove the plastic wrap or foil from the dish. Place the casserole in the preheated oven and bake for 45 to 55 minutes.
- Check for Doneness: The casserole is finished when the center is set (no longer jiggly), the edges are golden brown, and a knife inserted near the center comes out clean. If the top begins to brown too quickly (before the center is set), loosely cover the dish with aluminum foil for the last 10 to 15 minutes of baking time to protect the cheesy topping.
- Rest and Serve: Remove the finished casserole from the oven and allow it to rest for 5 to 10 minutes before slicing and serving. This resting period helps the casserole set completely and makes serving much easier, preventing it from collapsing when cut.
Serve your beautiful, piping hot Cheesy Sausage Breakfast Casserole with a side of fresh fruit or a light salad for a complete and satisfying meal. For another easy breakfast idea perfect for a crowd, consider making Pumpkin Cream Cheese Cinnamon Rolls a sweet counterpoint to this savory bake!
Tips, Tricks, and Delicious Variations for Your Breakfast Casserole
Once you’ve mastered the core recipe for Cheesy Sausage Breakfast Casserole, you can start experimenting! These tips and variations help you adapt the recipe to any dietary need or flavor craving.
Ingredient Alternatives and Swaps
Bread Base Alternatives
While day-old bread is ideal, you can use several alternatives:
- Gluten-Free: Use gluten-free sandwich bread, ensure it is sturdy and cut into 1-inch cubes.
- Croissants or Biscuits: Use torn croissants or diced refrigerated biscuit dough for an extra buttery, richer casserole base.
- Hash Browns: For a bread-free savory dish, create a layer of defrosted hash browns mixed with a tablespoon of melted butter on the bottom before adding sausage and cheese. This turns it into a hash brown breakfast casserole.
Meat and Protein Substitutions
If you don’t have bulk sausage, or want a lighter option, try these swaps:
- Ham or Bacon: Use 1 cup of diced, cooked ham or 1 pound of crispy, crumbled bacon.
- Spicy Chorizo or Italian Sausage: For a deeper, spicier flavor, swap out the standard breakfast sausage.
- Vegetarian Option: Omit the meat entirely or substitute with 1 pound of sautéed mushrooms, bell peppers, spinach, or plant-based sausage crumbles. Ensure vegetables are fully cooked and excess moisture is drained before layering.
Cheese Variations
If you prefer a milder flavor or want to use what you have on hand, consider:
- Monterey Jack or Colby Jack (milder melt).
- Pepper Jack (for a spicy kick).
- Swiss or Gruyère (for a nutty, sophisticated flavor profile).
You can also use a mixture of cheeses Cheddar remains the foundation, but adding 1/2 cup of a complementary cheese can add complexity to your Cheesy Sausage Breakfast Casserole.
Tips to Avoid Common Casserole Mistakes
Preventing a Soggy Casserole
The number one mistake is skipping the overnight chill. The 8-12 hour soak is non-negotiable for a custardy, non-soggy result. Additionally, make sure you drain the sausage completely after cooking. Any leftover grease will settle at the bottom and create a wet, oily base.
The Importance of Room Temperature Baking
Removing the casserole from the fridge 30 minutes before baking helps prevent the center from remaining cold and unset while the edges burn. Cold dishes require significantly longer cooking times, which often leads to uneven results.
Freezing and Reheating
This Cheesy Sausage Breakfast Casserole freezes well!
- To Freeze Unbaked: Prepare through Step 7, but do not bake. Wrap tightly in foil (use two layers) and freeze for up to 3 months. Thaw completely in the refrigerator (takes about 24 hours) before baking as directed. Add 10-15 minutes to the bake time if baking straight from the fridge.
- To Freeze Baked: Cool completely, cut into individual portions, wrap in plastic wrap and foil, and freeze. Reheat thawed portions in the microwave or oven (350°F) until warmed through.
Scaling the Recipe
If you need to make this for a smaller group, you can halve the recipe and bake it in an 8×8 inch square dish. Note that the baking time will likely be reduced to 35-45 minutes. Always check the center with a knife for doneness, regardless of pan size.
Nutritional Values and Benefits of this Cheesy Sausage Breakfast Casserole
While this Cheesy Sausage Breakfast Casserole is undoubtedly comfort food, it provides significant nutritional benefits, particularly for individuals seeking a high-protein start to their day. Since ingredients can vary (especially the sausage type), the following values are estimates per serving (based on dividing the 9×13 casserole into 12 generous portions).
Estimated Nutritional Breakdown (Per Serving of 1/12th Casserole)

Protein | 20 – 25 grams |
Fat (Total) | 25 – 30 grams |
Saturated Fat | 12 – 15 grams |
Carbohydrates (Net) | 10 – 15 grams |
Note: These values are based on using mild bulk sausage, whole milk, and white bread, and represent averages. Using lean sausage or half-and-half will slightly shift the fat and calorie counts.
Health Benefits of Key Ingredients
High-Quality Protein from Eggs and Sausage
Eggs are often called nature’s perfect food because they contain all nine essential amino acids. The combination of 10 eggs and a pound of sausage makes this Cheesy Sausage Breakfast Casserole an excellent source of protein, which is essential for muscle repair, hormone regulation, and providing steady energy throughout the morning. High-protein breakfasts are proven to increase satiety and reduce mid-morning snacking.
Calcium and Vitamin D from Dairy
Whole milk and cheddar cheese contribute significantly to calcium intake, crucial for bone health. They also provide Vitamin D, which aids in calcium absorption, and healthy fats that help the body absorb fat-soluble vitamins found in other foods consumed during the meal.
B Vitamins and Iron
Breakfast sausage and eggs are good sources of B vitamins (like B12 and choline), which are vital for nerve function and metabolism. The meat also contributes iron, necessary for oxygen transport in the blood. Although this is a richer breakfast option, the macronutrient balance ensures it is highly satisfying and nutrient-dense.

Frequently Asked Questions about Cheesy Sausage Breakfast Casserole
How do I prevent my Cheesy Sausage Breakfast Casserole from being soggy?
The key to preventing a soggy casserole is twofold: first, ensure you thoroughly drain the cooked sausage of all grease before layering. Second, the overnight rest (8-12 hours) is crucial. This allows the bread to fully hydrate and bind with the egg mixture, creating a firm, custardy texture when baked instead of a wet one.
Can I use frozen sausage for this breakfast casserole?
Yes, you must use cooked and crumbled sausage for the casserole. If your sausage is frozen, ensure you thaw it completely before cooking it in the skillet and draining the excess fat. Do not add raw or frozen sausage directly to the casserole mixture.
What is the best type of bread to use for a sausage egg casserole?
Sturdy, slightly dense bread works best, such as day-old French bread, sourdough, or Texas toast. Avoid soft, basic white sandwich bread, as it tends to break down too much during the overnight soak. Using day-old bread is ideal because the slight staleness helps it maintain its structure while absorbing the custard.
How do I know when the Cheesy Sausage Breakfast Casserole is fully cooked?
The casserole is done when the edges are golden brown, the cheese is bubbling, and the center no longer jiggles when the pan is gently nudged. The most reliable test is inserting a knife near the center; if it comes out clean, the egg custard has set completely.
Can I prepare and bake this casserole on the same day?
While you technically can bake it right away, the results will be inferior. The bread needs time to soak up the liquid to achieve the proper consistency. If you are short on time, allow a minimum soaking period of 3 hours, but know that 8-12 hours provides the best, most custardy Cheesy Sausage Breakfast Casserole texture.
