Key Ingredients for the Best Sausage Casserole Recipe
Crafting this incredible breakfast casserole requires a short list of simple yet essential ingredients. Each component plays a vital role in achieving that perfect balance of flavor and texture:
- Bulk Breakfast Sausage: This is the star of the show! You can choose hot or mild, depending on your preference for a little kick or a gentler flavor. Brands like Jimmy Dean or Odom’s Tennessee Pride are excellent choices, known for their consistent quality. I personally lean towards hot sausage because it surprisingly isn’t intensely spicy but adds a depth of savory flavor that elevates the entire dish. Don’t be afraid to experiment with different types of ground sausage, such as turkey sausage for a leaner option, or even a plant-based alternative for a vegetarian version. Just ensure it’s “bulk” sausage, not links, for easy crumbling.
- A Dozen Eggs: Yes, you read that right – a full twelve eggs! This generous quantity ensures a wonderfully fluffy and substantial egg base that holds all the delicious ingredients together. The eggs provide the structure and richness that make this casserole so satisfying.
- Sharp Cheddar Cheese: Freshly shredded sharp cheddar cheese is non-negotiable for its robust flavor and excellent melt. While pre-shredded cheese is convenient, shredding your own from a block will give you a superior melt and a richer taste, as pre-shredded varieties often contain anti-caking agents. Feel free to explore other cheeses like Monterey Jack, Colby, or a cheddar blend for a different flavor profile, but sharp cheddar offers that classic, comforting taste.
- A Can of Condensed Cream of Mushroom Soup, Undiluted: This is the secret ingredient that makes this casserole so incredibly light and fluffy despite having heavy ingredients. Just plop the entire can directly into your mixture – no need to dilute it. The cream of mushroom soup acts as a binder, adds a creamy richness, and contributes to the casserole’s moist and tender texture, preventing it from drying out. If you’re not a fan of mushroom, condensed cream of chicken soup can be a suitable alternative.
- A Pinch of Kosher Salt: While the soup and cheese already contribute saltiness, a pinch of kosher salt helps to enhance all the flavors. Adjust to your taste, remembering that you can always add more at the table.
- Fresh Cracked Black Pepper: Freshly cracked black pepper provides a wonderful aromatic warmth and a subtle bite that complements the rich flavors of the sausage and cheese. Grind it generously for the best results.
With these simple ingredients, you’re well on your way to creating a truly unforgettable breakfast casserole!

Step-by-Step Guide: How to Make the Best Sausage Breakfast Casserole
Making this sausage breakfast casserole is incredibly simple, requiring minimal effort for maximum flavor. Follow these straightforward steps to achieve a perfectly baked, golden-brown casserole:
Preparation is Key: Get Started
First things first, preheat your oven to 350°F (175°C). While the oven is warming up, you’ll prepare the casserole mixture. This recipe is designed for efficiency, allowing you to get everything ready in just a few minutes.
Cooking the Sausage:
In a large skillet, cook your bulk breakfast sausage over medium-high heat. Use a wooden spoon or spatula to break up the sausage into small, even crumbles as it cooks. Continue cooking until the sausage is thoroughly browned and no longer pink. This step is crucial for developing deep, savory flavors. Once cooked, drain any excess fat from the skillet. This prevents the casserole from becoming greasy. A fantastic time-saving tip: you can cook the sausage a day or two in advance and store it in the refrigerator. Even better, cooked sausage freezes beautifully, allowing you to always have some on hand for quick casserole assembly!
Whisking the Eggs:
Crack all twelve eggs into a large mixing bowl. Now, here’s a personal preference that makes a difference: instead of a traditional whisk, I find that a good old-fashioned fork works wonders for whisking the eggs. Apply a little “elbow grease” and vigorously whisk the eggs until they are truly well-mixed and fluffy. You want them light and airy, as this contributes to the casserole’s final texture.
Combining the Ingredients:
Once your eggs are whisked, it’s time to bring everything together. Add the cooked and drained sausage, shredded sharp cheddar cheese, the entire can of undiluted condensed cream of mushroom soup, a pinch of kosher salt, and fresh cracked black pepper to the bowl with the eggs. Continue using your fork to mix everything. Don’t be alarmed if the cream of mushroom soup doesn’t fully dissolve; it will break up into visible white bits throughout the egg mixture. This is completely normal and contributes to the casserole’s signature light and fluffy texture, rather than a dense, heavy one.
Baking to Perfection:
Lightly grease a 2-quart baking dish (a standard 13×9 inch dish works perfectly) with cooking spray. Pour the entire egg mixture evenly into the prepared dish. Transfer the dish to your preheated oven and bake for 30-40 minutes. The casserole is done when it achieves a beautiful golden-brown color on top, appears puffed in the center, and the egg mixture is completely set throughout. To confirm doneness, gently jiggle the dish; the center should not move or appear liquid. Alternatively, lightly press the center with a clean finger; there should be a firm resistance. Avoid overbaking, as this can lead to a dry casserole.
PRO TIP! For an extra layer of flavor and a slightly savory, smoky finish, dust a little Old Bay seasoning over the top of the casserole before baking or right after it comes out of the oven. It adds a delicious coastal twist!

When to Serve This Versatile Sausage Casserole
The beauty of this sausage casserole lies in its incredible versatility. While it’s a breakfast staple, it’s hearty and satisfying enough to be enjoyed any time of day. When I first learned this recipe, the family I got it from made it like clockwork – usually one Sunday a month, and it was always a highly anticipated event. While I don’t cook as much on weekends, I particularly love this recipe for a variety of special and everyday occasions:
- Holidays: Christmas morning, Easter brunch, or Thanksgiving breakfast call for something special yet easy. This casserole allows you to spend less time in the kitchen and more time with loved ones.
- Potlucks: It’s a fantastic dish to bring to a potluck. It travels well, feeds a crowd, and is almost universally adored, guaranteeing an empty dish by the end of the event.
- Brunch: Whether it’s a casual weekend brunch with friends or a more elaborate affair, this casserole fits right in, offering a savory anchor to your spread.
- When You Have Company: Hosting overnight guests? Prepare this casserole the night before, and wake up to an easy, impressive breakfast that will make your guests feel right at home.
- Father’s Day: Treat Dad to a hearty, flavorful breakfast that shows him how much you care, without all the morning rush.
- Breakfast for Dinner: There’s something wonderfully comforting about “brinner.” This casserole makes a fulfilling and fun dinner option, especially on a chilly evening.
- Special Occasions: Think breakfast in bed for a birthday, an anniversary morning, or any time you want to make an ordinary day a little more extraordinary.
SMART TIP! To make your morning even easier, cook and crumble the sausage the day before you plan to bake the casserole. Store it in the refrigerator, and then all you have to do in the morning is whisk the eggs and combine the ingredients. This simple step cuts down significant prep time!

Perfect Pairings: What to Serve with Your Sausage Casserole
This savory sausage, egg, and cheese casserole is a meal in itself, but it truly shines when paired with complementary sides that add balance and variety to your breakfast or brunch spread. Here are some of our favorite accompaniments:
- Classic Southern Buttermilk Biscuits: Flaky, tender, and perfect for soaking up any delicious casserole juices, classic buttermilk biscuits are always the right choice. For those watching their carbs, my Low Carb Cheddar Bay Biscuits offer a fantastic, flavorful alternative.
- Fresh Fruit Platter: A vibrant assortment of fresh berries, sliced melon, grapes, or citrus segments provides a refreshing contrast to the rich casserole. It adds a healthy, light element and a pop of color to your table.
- Breakfast Potatoes: You can’t go wrong with potatoes! Crispy Griddle Hash Browns are a fantastic option for a classic diner feel. If you prefer another make-ahead casserole, my Jalapeno Hash Brown Casserole adds a bit of a kick and can be prepared in advance.
- Cream Gravy: For an extra layer of indulgent comfort, a drizzle of warm cream gravy over a slice of casserole is simply divine. It ties all the savory flavors together beautifully.
- Sweet Breakfast Staples: Balance the savory with a touch of sweetness. Fluffy pancakes or waffles served alongside the casserole create a delightful sweet and savory brunch experience.
- Croissants or Toast: As a lighter alternative to biscuits, warm, buttery croissants or simple toast provide a lovely base for any extra egg or sausage.
- Deviled Eggs: While traditionally a side dish for lunch or dinner, deviled eggs can add an unexpected and delicious element to a robust breakfast spread, especially for a holiday brunch.
- Muffins or Quickbread: Sweet muffins (blueberry, banana nut) or slices of homemade quickbread, such as moist Banana Bread, offer another sweet complement to your savory casserole.
- Beverages: Don’t forget the drinks! Freshly brewed coffee, a pitcher of orange juice, or even a mimosa for a celebratory brunch completes the meal.

Frequently Asked Questions About Sausage Breakfast Casserole
Absolutely! This casserole is incredibly convenient for make-ahead preparation. You can assemble the entire dish, cover it tightly with foil or plastic wrap, and refrigerate it overnight (up to 24 hours). In the morning, simply remove it from the fridge while your oven preheats, then bake as directed. While it’s best served fresh from the oven, this particular recipe has more staying power than many other egg casseroles that tend to shrink and shrivel after cooking. It reheats beautifully.
To ensure freshness and flavor, store any leftover sausage breakfast casserole in an airtight container or covered tightly with foil or plastic wrap in the refrigerator for up to 3 days. For longer storage, you can freeze individual portions. Wrap slices tightly in plastic wrap, then aluminum foil, and store in a freezer-safe bag for up to 1-2 months. Thaw overnight in the refrigerator before reheating.
For individual portions, the microwave is your best friend. Place a slice on a microwave-safe plate, cover loosely, and heat for 1-2 minutes, or until warmed through. For larger portions or an entire casserole, cover it with foil and reheat in an oven at 300°F (150°C) for 15-25 minutes, or until hot in the center. The oven method helps maintain a better texture.
Certainly! This casserole is very adaptable. Feel free to sauté diced onions, bell peppers, spinach, or mushrooms with the sausage (or separately) before adding them to the egg mixture. Just make sure to cook down any vegetables that release a lot of water to prevent a watery casserole.
While cream of mushroom soup is our secret for that fluffy texture, you can substitute it with another condensed cream soup, such as cream of chicken or cream of celery, for a slightly different flavor profile. The key is using an undiluted condensed soup for its binding and tenderizing properties.
