How To Make Easy Breakfast Casserole

Prepare Baking Dish. Lightly spray a 9 x 13-inch baking dish with cooking spray.

Cubed Bread. Layer cubed bread into prepared baking dish.

Cook Sausage. Cook sausage in a medium skillet over medium heat until crumbled and browned. Drain and layer sausage over bread cubes.

Whisk Eggs. Place eggs, milk, pesto, Italian seasoning, salt and pepper into a medium mixing bowl. Whisk to combine. Pour over sausage and bread mixture.

Add Toppings. Top with Parmesan cheeses, tomatoes and green onions.

Add Mozzarella Cheese. Add shredded mozzarella cheese evenly over top of casserole. From this step, you can either bake right away, 350 degrees F. for about an hour or refrigerate overnight.

Cover and Refrigerate. Cover with foil and refrigerate overnight or at least 3 hours.

Preheat Oven and Bake. When ready, remove dish from oven and preheat oven to 350 degrees F. Bake dish for 55-60 minutes, until set. Before serving, top with fresh sliced basil leaves. Cut into squares.

Tips For Overnight Casserole

Here are some helpful tips for making the best overnight breakfast casserole.

• Prepare in Advance. Prepare this recipe a couple days before actually serving.
• Cover and Refrigerate. Cover tightly with foil and keep in refrigerator.
• Let Sit at Room Temp Before Baking. Remember to take out of refrigerator a couple hours before ready to bake if possible. Having the dish more room temperature will keep cook time the same as recipe states.
• Longer Cook Time If Cooking Straight From Refrigerator. If dish comes right out of the refrigerator to the oven, you may need to bake longer.

How To Store Leftovers

• Refrigerate. Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat as needed.
• Freezing Instructions. If you are freezing the breakfast casserole, cover very tightly with aluminum foil or scoop cooked casserole into an airtight container or freezer safe bag. Freezer for up to 3 months.
• Reheating Instructions. Reheat refrigerated breakfast casserole on a heat proof plate in the microwave, covered lightly for about 60 seconds or until hot. If reheating frozen casserole, thaw before reheating. Same instructions as refrigerated.
