Ingredients for baked egg and sausage casserole
Twelve eggs, crispy sausage, and golden cheese create this brunch showstopper. Perfect for crowds or meal prep.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 12 whole | Room temperature for even cooking |
| Breakfast Sausage 🌭 | 1 ½ lb | Pre-cooked, crumbled or sliced |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, sharp flavor preferred |
| Milk 🥛 | 1 ½ cups | Whole milk for creaminess |
| All-Purpose Flour 🌾 | ½ cup | For crispy topping texture |
| Butter 🧈 | ½ cup | Unsalted, melted for binding |
| Garlic Cloves 🧄 | 4 cloves | Minced for aromatic depth |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | 1 tsp | Freshly cracked for flavor |
| Dried Parsley 🌿 | 1 tbsp | For vibrant color and freshness |
| Hot Sauce 🌶️ | 1 tbsp | Optional for serving |
| Fresh Green Onion 🧅 | ¼ cup | Chopped for garnish |
The sausage is the flavor foundation here. Johnsonville or Bob Evans are my go-tos—they crumble perfectly and stay juicy. If using fresh sausage, cook it thoroughly first and drain the fat. For the eggs, room temperature is key to prevent cracking when layering. The sharp cheddar? Kraft 2% or Pepper Jack both work, but avoid pre-shredded (it has anti-caking agents that prevent melting). The milk should be whole for that rich, custardy texture—skim won't give the same result.
No sharp cheddar? Monterey Jack or Gouda work in a pinch, though the flavor will be milder. Short on milk? Half-and-half or heavy cream adds richness, but reduce by 2 tbsp to maintain consistency. The flour is non-negotiable for that crispy top—it's what creates that golden, crunchy crust. Need to make it ahead? Assemble the casserole, cover, and refrigerate up to 24 hours before baking. The garlic can be pre-minced and stored in the fridge for 1 week in an airtight container.
This reheats beautifully—just 10 minutes at 325°F to warm through. Keeps for 4 days in the fridge, though the texture gets slightly softer. For meal prep, portion into individual ramekins before baking—each serves one and reheats perfectly. The hot sauce and green onions are purely for serving, but I always keep a stash of both on hand. They add a nice pop of color and let everyone customize their heat level.

Step-by-step instructions for baked egg and sausage casserole
Here's how to create the perfect golden crust and creamy, runny yolks every time.
🍳 Step 1: Cook the Sausage and Build the Base
Heat a large skillet over medium heat and add the 1.5 lb breakfast sausage. Cook, breaking it into even crumbles, until fully browned and any released liquid evaporates—about 8-10 minutes. You're aiming for crispy bits, not greasy sausage.
Transfer the cooked sausage to a greased 9x13-inch baking dish and spread it evenly. In the same skillet, melt the 0.5 cup butter over medium-low heat, then add the 4 minced garlic cloves and cook for 30 seconds until fragrant. Pour this butter-garlic mixture over the sausage in the baking dish.
👨🍳 Step 2: Prepare the Egg Mixture
In a large bowl, whisk together the 12 room-temperature eggs, 1.5 cups milk, 0.5 cup all-purpose flour, 1.5 tsp salt, and 1 tsp ground black pepper until completely combined. The batter should be smooth with no visible streaks of flour.
Stir in the 2 cups shredded sharp cheddar cheese and 1 tbsp dried parsley until evenly distributed. Here's the thing—don't worry if the cheese doesn't fully dissolve. We want visible cheese throughout for maximum flavor and texture contrast.
🥘 Step 3: Assemble and Bake for Crispy Perfection
Pour the egg mixture evenly over the sausage in the baking dish. The liquid should come about ¾ of the way up the sides of the dish—this ensures a thick, crispy crust without overflowing. Gently tap the dish on the counter to release any air bubbles that may have formed.
Bake at 350°F for 45-50 minutes until the edges are deep golden brown and the center still looks slightly jiggly when gently shaken. The key is patience—resist opening the oven door early. The top should be crisp enough to hold its shape when you lift a corner.
⏰ Step 4: Rest and Serve with Flavor Boosters
Remove the casserole from the oven and let it rest for 10 minutes before serving. This resting period allows the custard to set slightly while keeping the yolks gloriously runny. If you cut into it too soon, the center will be too soft and the crust may collapse.
Garnish each serving with chopped fresh green onion and a drizzle of hot sauce if desired. The crispy top should contrast beautifully with the creamy egg center, and the sharp cheddar will melt perfectly into each bite. Serve immediately with toasted bread or a simple side salad.
Pro Tips For Making Baked Egg And Sausage Casserole
- CRACK EGGS LAST MINUTE: I used to prep everything ahead—including cracking eggs—only to watch them weep into the milk mixture. Crack them right into the bowl with the milk and flour, then whisk gently to avoid over-aerating. The eggs stay intact longer, and the custard turns out smoother.
- USE COLD SAUSAGE: Skip browning the sausage first—just crumble it raw into the casserole. The fat renders in the oven, and you avoid that greasy, overcooked texture. If you’re worried about doneness, add 5 extra minutes to the bake time.
- STIR BEFORE BAKING: After mixing the egg-milk slurry, give the casserole a single stir to distribute the cheese evenly. Then stop. Overmixing creates a dense, rubbery top. The cheese will melt into pockets of gooeyness—just leave it alone after that first stir.
- CHILL THE BATTER: Let the egg-milk-cheese mixture sit for 10 minutes before baking. I learned this the hard way—hot oven + warm custard = a sad, watery mess. A quick fridge break helps the eggs set properly and prevents a soupy finish.
Storing and reheating your baked egg and sausage casserole
Fridge Storage Tips
Store your baked egg and sausage casserole in an airtight container for up to 4 days in the fridge. I like using glass Pyrex dishes with tight-fitting lids—they keep flavors locked in and reheat beautifully. Let it cool completely before covering to prevent condensation buildup, which can make the top soggy. 🥗
Freezer-Friendly Prep
This casserole freezes surprisingly well for up to 3 months in a heavy-duty freezer bag or airtight container. After baking, cool completely, then portion into individual servings before freezing. Leave ½-inch headspace for expansion, and label with the date. Thaw overnight in the fridge before reheating.
Oven Reheating Method
For the best texture, reheat in a 350°F oven for 15-20 minutes covered with foil, then uncover for the final 5 minutes to crisp the top again. A light spray of water on the foil helps restore moisture without making it soggy. I always reheat mine this way—it brings back that perfect golden crust!
Microwave Shortcuts
When you're in a hurry, microwave individual portions on 50% power for 2-3 minutes, stirring halfway. Cover loosely with a damp paper towel to prevent drying. Add 1 tbsp milk or water if it looks dry—this helps restore the creamy texture without overpowering the flavor. 💫
Make-Ahead Assembly
Assemble the casserole in your baking dish, cover tightly with plastic wrap, and refrigerate for up to 24 hours before baking. This actually improves flavor as the spices meld together. Just add 5-10 extra minutes to the baking time if starting cold from the fridge.
Portion Control
For meal prep, divide into individual ramekins before baking—each serves one perfectly. Reheat at 325°F for 10 minutes or microwave for 1 minute. The crispy top will soften slightly but still taste amazing. Keep portions covered to maintain moisture during storage.

Frequently asked questions
Can I use fresh sausage instead of pre-cooked?
Yes, but you must cook it thoroughly first to avoid food safety risks. Brown 1.5 lb fresh sausage in a skillet over medium heat for 12-15 minutes, breaking it into crumbles and draining excess fat. This ensures it's fully cooked before layering—just like with pre-cooked sausage. The texture will be slightly different but still delicious!
Why did my casserole turn out too dry?
Overbaking is the most common cause. The center should look slightly jiggly when you gently shake the dish—this means the eggs are still custardy inside. If yours was dry, try reducing the baking time by 5-10 minutes next time. Also, ensure your eggs and milk are at room temperature to help maintain moisture. A splash of extra milk in the egg mixture can help too!
How can I make this casserole ahead for a brunch crowd?
Assemble the casserole in your baking dish the night before, cover tightly with plastic wrap, and refrigerate. When ready to bake, add 10-15 extra minutes to the baking time since it'll start cold. For even easier prep, bake individual ramekins—just portion the egg mixture into 6-8 greased ramekins before baking. They reheat beautifully and let guests serve themselves!
Can I substitute the sharp cheddar with another cheese?
Monterey Jack or Gouda work well for a milder flavor, while Pepper Jack adds a subtle kick. Avoid pre-shredded cheese—it contains anti-caking agents that prevent proper melting. If you're out of sharp cheddar, try Gruyère for a nutty depth. Just shred it yourself for the best results!
What's the best way to reheat leftovers?
For the crispy top you love, reheat in a 350°F oven for 15-20 minutes covered with foil, then uncover for the final 5 minutes. For quick reheating, microwave individual portions on 50% power for 2-3 minutes, stirring halfway. Add 1 tbsp milk if it looks dry—this restores the creamy texture without overpowering the flavor.
