Casserole Preparation

Preparing the Overnight Bisquick Breakfast Casserole is simple and straightforward, with just a few steps to bring everything together. The key to this recipe is assembling it the night before, allowing the flavors to meld and making your morning routine that much easier.

Step 1: Cook the Sausage and Bacon

Start by spraying a 9 x 13-inch baking dish with nonstick cooking spray, then set it aside. In a large skillet over medium-high heat, brown the ground sausage until it’s no longer pink. Once cooked, drain off any excess grease and transfer the sausage to the prepared baking dish.

Next, use the same skillet to cook the bacon over medium heat until it’s crispy. Remove the bacon from the skillet and place it on a paper towel-lined plate to drain. Once cooled, chop or crumble the bacon into small pieces, ready to be added to the casserole.

Step 2: Add Vegetables and Cheese

To the sausage in the baking dish, add the cooked bacon, finely-diced green bell pepper, onion, and grated sharp cheddar cheese. Stir everything together to evenly distribute the ingredients, ensuring that every bite will be packed with flavor.

Step 3: Prepare the Egg Mixture

In a large mixing bowl, whisk together the eggs, whole milk (or heavy cream), Bisquick, and melted butter. Continue whisking until the mixture is smooth and all ingredients are fully combined. This will form the base of your casserole, providing a fluffy and creamy texture once baked.

Step 4: Assemble the Casserole

Pour the egg mixture evenly over the sausage, bacon, vegetables, and cheese in the baking dish. Be sure that all ingredients are well-covered with the egg mixture to ensure even cooking. Once assembled, cover the baking dish with plastic wrap or aluminum foil and refrigerate it overnight. This allows the flavors to meld together and ensures the casserole is ready to be baked the next morning.

Baking and Serving the Casserole

The morning has arrived, and your Overnight Bisquick Breakfast Casserole is ready to be baked! This step is simple and results in a golden, bubbly casserole that’s perfect for breakfast.

Step 5: Let the Casserole Come to Room Temperature

Before you start baking, take the casserole out of the refrigerator and allow it to sit on the counter for about 30-60 minutes. This helps it come to room temperature, ensuring even baking. Preheat your oven to 350°F (175°C) while the casserole is resting.

Step 6: Bake the Casserole

Place the baking dish in the preheated oven and bake uncovered for 50-60 minutes. Keep an eye on the casserole as it bakes—when the top is browned and the eggs are set in the center, it’s ready! The casserole should be slightly puffed up and golden brown on top. You can check for doneness by inserting a toothpick in the center; if it comes out clean, your casserole is perfectly baked.

Step 7: Let It Rest

After removing the casserole from the oven, let it rest for at least 10 minutes before slicing. This allows the casserole to set, making it easier to serve without falling apart.

Garnish and Serve

Just before serving, garnish the casserole with sliced green onions or fresh herbs like parsley or chives for a burst of color and freshness. Serve it warm and enjoy the savory flavors in every bite. This casserole is perfect on its own or served with a side of fruit or toast for a complete breakfast.

Storage Instructions

After enjoying your delicious Overnight Bisquick Breakfast Casserole, you’ll want to know how to keep any leftovers fresh. Proper storage ensures you can enjoy this comforting dish for a few more days or even reheat it for a quick breakfast.

How to Keep the Casserole Fresh

If you have leftovers, store them in an airtight container in the refrigerator. The casserole will stay fresh for up to 3 days. To reheat, simply place a slice in the microwave for 30-60 seconds, or warm it up in the oven at 350°F (175°C) for about 10 minutes until heated through.

Freezing the Casserole

If you want to keep your casserole for a longer period, you can freeze it! First, allow the casserole to cool completely. Then, wrap it tightly in plastic wrap and foil or place it in a freezer-safe container. This casserole can be frozen for up to 1-2 months. When you’re ready to enjoy it, thaw it overnight in the refrigerator and reheat as desired.
