Ingredients You’ll Need

Here’s your grocery list. Nothing fancy. Just the basics that work every single time.

• 1 lb ground pork sausage (you can use spicy if you like a kick)
• 10 large eggs
• 1 cup heavy cream (or full-fat milk if you’re not strict keto)
• 1 ½ cups shredded cheddar cheese (sharp works great)
• ½ teaspoon salt
• ¼ teaspoon black pepper
• Butter or oil for greasing the pan

Optional add-ins:

• Chopped spinach
• Sautéed mushrooms
• Diced bell peppers
• Green onions
• A sprinkle of paprika on top

You don’t need all the extras, but they give it that “made with love” taste.

How to Make this Sausage Egg & Cheese Breakfast Casserole 

This isn’t one of those fussy recipes where you’re stuck stirring and watching the clock. It’s the kind you can throw together half-asleep, then sit back while the oven does the heavy lifting. Here’s how to get it done right, with zero stress.

Step 1: Preheat the Oven

First things first—get that oven going. Set it to 375°F (190°C) so it’s hot and ready by the time you’re done mixing.

Grab a 9×13-inch baking dish and grease it well. Butter works great for flavor, but cooking spray or a bit of oil does the job too. Don’t skip this step—nobody likes scraping egg off a pan.

Step 2: Brown the Sausage

Take a large skillet and put it over medium heat. Crumble in your sausage. If you’re using links, just remove the casing and break it up with a spoon.

Cook it until it’s browned and no longer pink, stirring every now and then so it cooks evenly. This usually takes about 6 to 8 minutes. Once it’s done, remove the pan from heat and drain any extra grease. You don’t need the extra fat in the casserole.

Set the sausage aside for a couple of minutes so it’s not steaming hot when it hits the eggs.

Step 3: Whisk the Eggs & Cream

Crack 10 large eggs into a big mixing bowl. Pour in 1 cup of heavy cream, then add your salt and pepper. If you like other seasonings—garlic powder, onion powder, even a pinch of cayenne—you can add them here too.

Grab a whisk or a fork and beat everything together until the yolks and whites are fully combined and it looks smooth and slightly foamy. This step helps make the casserole light and fluffy instead of dense.

Step 4: Bring It All Together

Now the fun part.

Pour the cooked sausage into the egg mixture. Add the shredded cheese—you can use sharp cheddar, mozzarella, or whatever’s in your fridge. If you’re adding extras like chopped spinach, mushrooms, or bell peppers, toss them in now.

Use a large spoon or spatula to mix everything together gently. You want every bite to have a little sausage, egg, and cheese.

Then pour the whole mix into your greased baking dish. Use your spoon to spread it out evenly so it bakes up flat and nice.

Step 5: Bake Until Golden

Slide the dish into your hot oven. Set your timer for 30 to 35 minutes.

You’ll know it’s done when the top is golden and puffy, and the middle doesn’t jiggle when you shake the pan gently. If you’re unsure, stick a knife into the center—it should come out clean with no wet egg stuck to it.

Once it’s out of the oven, let it rest for 5 to 10 minutes before slicing. This helps it firm up a little, so you get neat slices that don’t fall apart. Plus, it’s piping hot straight from the oven—trust me, you don’t want to burn your tongue.

Make It Ahead

Freezer Friendly?

You bet. Slice it, wrap each piece, and freeze. Reheat in the oven or microwave when needed. It’s better than any frozen breakfast sandwich you’ve had, and it actually fills you up.
