Key Ingredients for Sausage and Egg Casserole
I always use quality sausage because it’s the star of this dish. My go-to is breakfast sausage for its classic flavor, but Italian sausage adds a nice herby kick if you’re feeling adventurous. Make sure to drain the grease well after browning to prevent a heavy casserole.
- 1 pound sausage (breakfast sausage, Italian, or spicy)
- 6 large eggs
- 1 cup milk (I recommend whole milk for the creamiest texture)
- 1 cup shredded cheddar cheese (or preferred cheese blend)
- 2 cups bread cubes (optional, use day-old bread for best results. If you only have fresh bread, cut it into cubes and let them sit out for a few hours, or toast them lightly at 300°F for 10 minutes to dry them out slightly)
- ½ teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
- ¼ teaspoon smoked paprika (adds a subtle warmth)
- ½ cup diced bell peppers (optional, I usually add red or green)
- ½ cup chopped spinach (optional)
- ¼ cup diced onions (optional)
In my experience, using full-fat dairy makes a noticeable difference in the final texture. The eggs come out fluffier and the whole casserole feels more satisfying. If you’re adding vegetables, make sure to dice them small so they cook evenly throughout.
How to Make Sausage and Egg Casserole
Gather all your ingredients before you start. This makes the process smooth and ensures nothing gets forgotten.
Step 1: Preheat your oven to 375°F (190°C). Lightly grease a 7×11-inch or 8×11-inch baking dish with butter or nonstick spray. This prevents sticking and makes cleanup easier later. Keep in mind that using a smaller dish will require longer baking time, while a larger dish may cook faster.
Step 2: Brown the sausage in a large skillet over medium heat, breaking it into small crumbles with your spatula as it cooks. This should take about 5-7 minutes until no pink remains and the edges are slightly crispy. Drain any excess grease and set the sausage aside. Don’t skip the draining step, as too much grease can make your casserole oily.
Step 3: In a large bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and smoked paprika until well combined. The mixture should be smooth with no streaks of egg white visible. This ensures even seasoning throughout.
Step 4: Spread the cooked sausage evenly across the bottom of your greased baking dish. If you’re using vegetables, sprinkle them over the sausage. Add the shredded cheese next, then top with bread cubes if desired. Pour the egg mixture slowly and evenly over everything, making sure it seeps into all the layers. The liquid should just cover the ingredients.
Step 5: Bake for 30-40 minutes, or until the center is completely set and the top turns golden brown. You can check doneness by gently shaking the dish. The center should be just barely set with a slight wobble (like Jell-O, not liquid). The edges will pull away slightly from the pan, and a knife inserted in the center should come out mostly clean with just a few moist crumbs. If the edges brown too quickly, tent with foil and continue baking.
Step 6: Let the casserole cool for 5 minutes before slicing. This allows it to set up properly and makes serving much easier. Serve warm and watch it disappear!
Recipe Variations
Want to switch things up? Try these delicious variations. For a spicy kick, use chorizo or add diced jalapeños to the mix. You can create a veggie-packed version by loading up on mushrooms, zucchini, and tomatoes. If you’re watching carbs, simply skip the bread cubes for a satisfying low-carb option, similar to my baked oats without banana which also offers a low-carb breakfast alternative.
My family loves the Italian twist using Italian sausage, mozzarella cheese, and fresh basil. For make-ahead convenience, assemble everything the night before, cover tightly, and refrigerate. Just add 5-10 extra minutes to the baking time. I discovered that adding a handful of frozen hash browns to the bottom creates an extra layer that everyone loves. Just thaw and squeeze out excess moisture before adding. You can also experiment with different cheese blends like pepper jack for heat, or Swiss for a milder flavor. If you enjoy experimenting with breakfast casseroles, you might also like my crockpot cabbage roll casserole for a hearty savory option.
What to Serve with Sausage and Egg Casserole
This hearty casserole pairs beautifully with lighter sides that add freshness and balance.
Fresh Fruit Salad: A colorful mix of berries, melon, and citrus provides a refreshing contrast to the rich, savory flavors. The natural sweetness and bright acidity cut through the cheese and sausage perfectly.
Crispy Hash Browns: Golden, crispy potatoes add a satisfying crunch and make the meal feel more complete. They’re especially popular with kids and hungry teenagers. Try my garlic butter steak bites and potatoes technique for perfectly crispy potatoes.
Simple Green Salad: Toss mixed greens with a light vinaigrette for a crisp, healthy side. The fresh vegetables add texture and help balance the protein-heavy main dish. My Greek yogurt cucumber salad also makes a wonderfully refreshing pairing.
Buttered Toast or English Muffins: Perfect for soaking up any extra egg mixture on your plate. Choose whole grain options for added fiber and nutrients. If you’re in the mood for something homemade, my honey cornbread recipe is a sweet complement to the savory casserole.
Avocado Slices: Creamy avocado adds healthy fats and a smooth texture that complements the eggs beautifully. Sprinkle with a little salt and lime juice for extra flavor.
Storage and Serving Tips
Store leftover casserole in an airtight container in the refrigerator for up to 4 days. I recommend cutting it into individual portions before storing, which makes reheating much easier for quick breakfasts throughout the week.
For reheating, microwave single servings for 1-2 minutes until heated through, or warm the entire dish in a 350°F oven for about 15-20 minutes. If you’re making this ahead for a crowd, you can assemble it completely the night before, refrigerate, and bake fresh in the morning.
This casserole freezes beautifully for up to 3 months. Let it cool completely after baking, then wrap portions tightly in plastic wrap and foil, or use freezer-safe containers. Thaw overnight in the refrigerator before reheating. Slightly underbake if you plan to freeze, as reheating will cook it further. For more make-ahead breakfast ideas, explore my cinnamon roll muffin recipe which also freezes wonderfully.

FAQ
Can I make this casserole without bread?
Absolutely! Simply omit the bread cubes for a delicious crustless version. The casserole will be slightly less dense but just as flavorful. This makes it naturally low-carb and gluten-free.
What’s the best way to prevent a watery casserole?
Make sure to drain the sausage thoroughly after cooking and don’t add too much liquid. If using frozen vegetables, thaw and pat them dry first. Also, let the casserole rest for 5 minutes after baking so it sets properly.
Can I use a different type of milk?
Yes, you can substitute with almond milk, oat milk, or any dairy-free alternative. However, whole milk or 2% milk gives the creamiest results. Avoid skim milk as it can make the texture less rich.
How do I know when the casserole is done?
The center should be completely set and not jiggly when you gently shake the pan. The top should be golden brown, and a knife inserted in the center should come out clean. If the edges are browning too fast, cover with foil.
