How to Make Easy Sausage and Egg Casserole Recipe

Step 1: Prepare the Bread

Start by cutting your white bread into cubes and letting them dry out a bit. This extra step helps the bread absorb the egg mixture without turning soggy, giving the casserole a perfect, tender bite with a hint of crustiness around the edges.

Step 2: Cook the Sausage

Brown the ground breakfast sausage in a skillet over medium heat, breaking it up as it cooks into delicious crumbles. This step infuses the entire casserole with those wonderfully savory and juicy flavors that every bite will celebrate.

Step 3: Whisk the Custard Mixture

In a large bowl, whisk together the eggs, whole milk, salt, black pepper, and dried mustard powder until smooth and frothy. This custard is what transforms the bread and sausage into that rich, satisfying casserole everyone will love.

Step 4: Assemble the Casserole

In a greased baking dish, layer the dried bread cubes evenly. Sprinkle half of the cooked sausage over the bread, then add half of the shredded cheddar cheese and chopped green onions. Pour half of the egg mixture over the layers and repeat with the remaining sausage, cheese, onions, and custard. This layering ensures every slice bursts with flavor and gooey cheese.

Step 5: Bake Until Golden and Set

Bake your casserole in a preheated oven at 350°F (175°C) for about 45 minutes. You’ll know it’s done when the top is golden brown, the cheese is bubbly, and the custard has set into a tender, sliceable perfection.

How to Serve Easy Sausage and Egg Casserole Recipe

A square piece of baked casserole sits centered on a white plate with a slightly raised edge. The dish shows three distinct layers: the bottom layer is a thick, crumbly cooked ground meat in brown, the middle layer is creamy and light-colored, likely a cheesy or egg base with soft texture, and the top layer is a golden-yellow melted cheese with bubbly, browned spots giving it a slightly crispy look. Small green herb leaves are scattered on top and around the plate as garnish. A gold fork lies to the right of the piece on the plate. The background is softly blurred but includes hints of green herbs and kitchen items on a white marbled surface. Photo taken with an iphone --ar 4:5 --v 7

Garnishes

A sprinkle of freshly chopped parsley or additional green onions gives a pop of vibrant color and a bright, fresh contrast to the rich casserole. A dash of hot sauce or a dollop of sour cream on top can also add extra excitement and creaminess if you like a little heat or tang.

Side Dishes

This casserole pairs beautifully with a simple mixed greens salad dressed in a light vinaigrette to cut through the richness. Fresh fruit salad or roasted breakfast potatoes also complement the savory meat and cheesy eggs perfectly for a well-rounded meal.

Creative Ways to Present

Serve this casserole straight from the baking dish family-style for a warm, homey feeling. Or for a more festive occasion, cut it into neat squares and plate each with a small garnish for individual servings. You can also make mini versions using muffin tins to create handheld portions great for brunch parties.

Make Ahead and Storage

Storing Leftovers

Wrap any leftover casserole tightly in plastic wrap or place it in an airtight container and refrigerate for up to 3 days. It maintains its creamy texture and flavors well, making it a convenient next-day breakfast or snack.

Freezing

This Easy Sausage and Egg Casserole Recipe freezes beautifully. Cool the baked casserole completely, then cover it tightly with foil and freeze for up to 2 months. When ready to enjoy, thaw overnight in the fridge before reheating.

Reheating

Reheat portions in the microwave for about 1 to 2 minutes until warmed through, or place the whole casserole in a 350°F oven covered with foil for 20-25 minutes. Reheating gently helps keep the eggs fluffy and cheese melty without drying out the bread.

FAQs

Can I use different types of bread for this casserole?

Absolutely! While white bread works wonderfully for fluffiness and soaking up the custard, you can also experiment with whole wheat or sourdough for a nuttier flavor and heartier texture.

Is it possible to make this casserole vegetarian?

Yes! Swap out the breakfast sausage for plant-based sausage crumbles or sautéed vegetables like mushrooms and bell peppers for a delicious vegetarian version.

Can I prepare this casserole the night before?

Definitely. Assemble the casserole, cover it with plastic wrap, and refrigerate overnight. In the morning, just pop it in the oven to bake. This is perfect for busy mornings or holiday brunches.

What kind of cheese works best besides cheddar?

Cheddar is a classic choice thanks to its sharpness and meltability, but feel free to use Monterey Jack, Swiss, or even a spicy pepper jack for a different twist on flavor and creaminess.

Can I add vegetables to this casserole?

For sure! Adding sautéed spinach, bell peppers, or mushrooms can enhance the dish with extra nutrients and flavor. Just be mindful of moisture content so the casserole doesn’t get soggy.
