• 1 pound cooked and drained sausage: Adds a savory, hearty punch that complements the eggs beautifully.
• 2 cups grated cheddar cheese: Melts into gooey, flavorful layers that bind the casserole together.
• 8 large eggs: The star protein that holds everything in a silky, rich custard form.
• 2 cups milk: Lightens the eggs and ensures the right custardy texture.

How to Make Best Overnight Sausage and Egg Casserole

Step 1: Prepare the Baking Dish

Start by preheating your oven to 325 degrees Fahrenheit. Grease a 9×13 inch baking dish generously to prevent sticking. Spread your cubed slices of bread evenly across the bottom, making sure each piece touches slightly to create a solid base. Trust me, using a sturdier bread like Pepperidge Farms Sourdough makes a world of difference, as it holds up beautifully after soaking overnight.

Step 2: Add the Sausage and Cheese

Once your bread layer is set, sprinkle the cooked and drained sausage evenly over the surface. Next, add the grated cheddar cheese, covering the sausage completely so every bite is loaded with gooey, savory goodness. This combination is where the magic begins to build in layers of flavor.

Step 3: Mix the Egg Mixture

In a large measuring cup or bowl, whisk together the eggs, milk, ground mustard, salt, and pepper until everything is thoroughly combined and smooth. This creamy mixture is the glue that brings all the components together, creating that luscious custard texture once baked.

Step 4: Assemble and Chill

Pour the egg mixture evenly over the layered bread, sausage, and cheese. You’ll want to cover the dish tightly with foil or plastic wrap before placing it in the refrigerator to chill overnight. This slow soaking process allows the bread to absorb the egg mixture fully, setting the stage for a perfectly cohesive casserole.

Step 5: Bake the Casserole

The next morning (or whenever your schedule allows), remove the casserole from the fridge and place it in the preheated oven. Cover loosely with foil for the first 30 minutes so the top doesn’t brown too quickly, then take the foil off to finish baking for another 15 to 25 minutes. The baking time depends on how you like your eggs, but a fork or knife inserted into the center should come out clean when done.

Step 6: Serve

Allow the casserole to cool for a few minutes after baking to let everything set a bit. Then slice and serve warm. The melding flavors and textures make this dish a standout for any breakfast or brunch occasion — trust me, it’s a crowd-pleaser!

How to Serve Best Overnight Sausage and Egg Casserole

Garnishes

Sprinkle a handful of freshly chopped chives or parsley to add a pop of bright color and fresh flavor. If you like a little heat, a dash of hot sauce or some sliced jalapeños works beautifully on top. A dollop of sour cream or a drizzle of mild salsa can also elevate each bite.

Side Dishes

This casserole pairs wonderfully with light, refreshing sides like a crisp mixed green salad or fresh fruit salad to counterbalance the richness. Toasted English muffins or flaky croissants are perfect for anyone wanting extra carbs to scoop up every last bit.

Creative Ways to Present

Serve the casserole in individual ramekins for charming single servings at your brunch table. Layer the ingredients in a clear glass casserole dish for a beautiful visual effect that shows off the melted cheese and sausage layered between the golden bread cubes. If you’re hosting, consider an assortment of toppings on the side so everyone can customize their slice.

Make Ahead and Storage

Storing Leftovers

After enjoying your Best Overnight Sausage and Egg Casserole, store any leftovers in an airtight container in the refrigerator. It will stay fresh for up to 3-4 days, making it a great option for quick breakfasts later in the week.

Freezing

This casserole freezes well! Slice it into portions, wrap them tightly in plastic wrap and foil, and freeze for up to 2 months. Thaw in the refrigerator overnight before reheating to enjoy that fresh-from-the-oven taste any day.

Reheating

Reheat leftovers in the oven at 350 degrees Fahrenheit for about 15-20 minutes until heated through, which helps preserve the casserole’s texture. Alternatively, using the microwave is fine for a quicker option but might result in a softer texture.

FAQs

Can I use a different type of bread?

Absolutely! While sturdier breads like sourdough hold up best, you can use French bread, whole wheat, or even a hearty white bread depending on your preference. Just avoid very soft or pre-sliced sandwich bread as it may get too soggy.

Is it possible to make this casserole vegetarian?

Yes! Simply swap the sausage for sautéed vegetables like mushrooms, bell peppers, or spinach. You might also consider plant-based sausage substitutes for a similar savory kick.

Can I prepare the casserole earlier in the day instead of overnight?

You can, but the flavors and texture develop best with an overnight soak. If pressed for time, let it sit for at least 2-3 hours before baking, but for optimal results, chill it overnight.

What cheese works best besides cheddar?

Cheddar is classic, but you can experiment with Monterey Jack, pepper jack for a little spice, or even mozzarella for a milder, stretchier cheese experience.

How do I know when the casserole is fully cooked?

Insert a fork or knife into the center of the casserole; it should come out clean without wet egg mixture clinging. The top will be golden and just firm to the touch.
