What is Easy Sausage and Egg Casserole?

Easy sausage and egg casserole is basically breakfast’s answer to the lasagna. Instead of noodles and sauce, you’ve got browned sausage, whisked eggs, shredded cheese, and milk all layered (or gently stirred) into a baking dish. It’s baked until golden and slightly puffed, then sliced like a dream. You can toss in some bread cubes if you want a heartier texture, or keep it low-carb by skipping them.

The beauty here is flexibility. Bell peppers, spinach, onions—add what you love or keep it bare bones for the traditionalists. It’s a dish that works just as well for a holiday brunch as it does for a Tuesday dinner. And let’s be honest, there’s something magical about a meal that lets you sleep in and still serve up something homemade and hot.

Instructions to Make Easy Sausage and Egg Casserole

If you’ve ever wished breakfast could make itself, this step-by-step guide is about as close as it gets. Making this easy sausage and egg casserole is a no-stress process, even if mornings aren’t your favorite. Each step walks you through the process with clarity, a touch of comfort, and helpful links to keep things as, well, easy as possible. Let’s get started!

Step 1: Preheat the Oven and Prep Your Dish

First things first—set your oven to 375°F (190°C). This gives it time to warm up while you prep everything else. A hot oven is key to getting that golden, cheesy crust on top.
Next, lightly grease a 7×11 or 8×11 baking dish with butter or nonstick spray. Want fewer dishes and an easier cleanup? You could also line the dish with parchment paper. A little effort here means zero sticking later.

Tip: If you’re meal-prepping, use a casserole dish with a lid so you can pop leftovers straight into the fridge. For more prep-friendly tips, check out our make-ahead casserole guide.

Step 2: Cook the Sausage

Heat a large skillet over medium heat. Add your choice of sausage—breakfast, spicy, or Italian—and cook until browned. Break it into crumbles with a wooden spoon or spatula as it cooks. This helps distribute the flavor throughout the dish and gives you that satisfying bite in every slice.
Once fully cooked, drain off any excess grease. We’re going for flavorful, not greasy. Set the cooked sausage aside to cool slightly.

Looking for a lower-fat option? Swap pork sausage for turkey sausage or even plant-based crumbles. For more smart swaps, check out our low-carb unstuffed cabbage casserole.

Step 3: Whisk the Egg Mixture

In a large mixing bowl, crack in 6 large eggs. Add 1 cup of milk, then season with ½ teaspoon each of salt, pepper, and garlic powder, plus ¼ teaspoon smoked paprika. Now whisk it all together until smooth and creamy.
This step is where the magic starts. The paprika gives a hint of smoky depth, while the milk ensures a soft, custardy texture after baking.

Tip: For a fluffier texture, whisk the eggs until slightly frothy. Want to add extra richness? Use half-and-half instead of milk.

Step 4: Assemble the Layers

Start by adding the cooked sausage to the bottom of your greased baking dish. Spread it out evenly—it’s the flavorful foundation of your casserole.
If you’re adding veggies like bell peppers, spinach, or diced onions, sprinkle them on top of the sausage now. They’ll soften beautifully in the oven and add both color and a nutritional boost.
Next, scatter 1 cup of shredded cheddar cheese evenly across the dish. Feel free to use a blend—Monterey Jack, mozzarella, or pepper jack all work wonders.

If you’re including bread cubes (totally optional), this is the moment. Two cups of day-old or lightly toasted bread help soak up the egg mixture and give a fluffy, bread pudding-like texture. For gluten-free or keto diets, just skip this step or substitute with low-carb bread.

Step 5: Pour the Egg Mixture

Now for the satisfying part. Slowly pour the whisked egg mixture over everything in the baking dish. Make sure it’s spread evenly and covers all the sausage, cheese, and optional bread or veggies.
If it looks like things are floating—don’t worry. The casserole will bake up firm and golden once it hits the oven.

Pro Tip: Let the dish rest for 5–10 minutes after assembling before baking. This gives the bread a chance to soak up the eggs for a more cohesive texture.

Step 6: Bake to Golden Perfection

Place the dish in your preheated oven and bake uncovered for 30 to 40 minutes. Keep an eye on it around the 30-minute mark. The center should be just set (no jiggle), and the top should be golden and slightly crispy around the edges.
A good visual cue: when a knife inserted into the center comes out clean, you’re good to go.

Want even more golden, cheesy topping? Sprinkle a bit of extra shredded cheese on top during the last 5 minutes of baking.

Step 7: Cool and Slice

After removing from the oven, let the casserole sit for at least 5 minutes. It’ll firm up a bit, making it easier to slice. Plus, you don’t want to burn your tongue in your rush to dive in—trust us.

Cut into squares and serve warm. Each bite delivers savory sausage, fluffy eggs, gooey cheese, and just the right amount of seasoning. You can dress it up with a dollop of sour cream or a dash of hot sauce if that’s your style.

What to Serve with Easy Sausage and Egg Casserole

Key Tips for Making Easy Sausage and Egg Casserole

Want to really knock this out of the park? Here are a few tips. First, use pre-cooked sausage if you’re low on time. Second, don’t skip greasing the pan—nothing’s worse than a stuck casserole. If using bread cubes, go for day-old or lightly toasted bread so it doesn’t turn soggy.

Want more flavor? Try a spicy sausage or a cheese blend like pepper jack or gouda. If you’re making it ahead, assemble everything and store covered in the fridge overnight. Let it sit at room temp for 15 minutes before baking the next morning. Oh—and always let it cool before slicing so it holds together like a champ. Want another hands-off crowd-pleaser?

Storage and Reheating Tips for Easy Sausage and Egg Casserole

Got leftovers? Lucky you. Store slices in an airtight container in the fridge for up to 4 days. To reheat, pop a slice in the microwave for about 60–90 seconds or warm in the oven at 325°F for 10–15 minutes. You can also freeze it! Wrap individual portions tightly in foil or plastic wrap, then place in a freezer bag. Freeze for up to 2 months. To reheat from frozen, thaw overnight in the fridge, then bake at 350°F until heated through (about 20–25 minutes). Pro tip: Add a little shredded cheese on top while reheating for extra meltiness. It’s like a breakfast encore.
