Step‑by‑Step Instructions for Bisquick Breakfast Casserole
Step 1: Preheat & Prepare
Begin by preheating your oven to 375°F (190°C). While the oven warms up, take a 9×13-inch baking dish and generously grease it with cooking spray or butter. This ensures your Bisquick Breakfast Casserole slides out smoothly after baking, keeping that perfect golden exterior intact.
Step 2: Cook the Sausage
Next, heat a skillet over medium heat and add your breakfast sausage. Cook the sausage for about 8-10 minutes, stirring occasionally until it turns golden brown and crumbles easily. Once cooked, drain the excess grease and set the sausage aside to cool slightly while you prepare the batter.
Step 3: Mix the Batter
In a large mixing bowl, whisk together 6 large eggs, 1 cup of milk, 1 cup of Bisquick mix, and a pinch of salt and pepper until the mixture is completely smooth. This step is crucial for creating that fluffy texture in your Bisquick Breakfast Casserole, so take your time to ensure there are no lumps.
Step 4: Assemble the Casserole
Spread the cooked sausage evenly across the bottom of the greased baking dish. Sprinkle your favorite shredded cheese, along with diced bell peppers and onions if using, over the sausage. Finally, pour the Bisquick mixture evenly over the top, making sure it covers all the ingredients underneath for a delicious layer of flavor.
Step 5: Bake & Serve
Place the assembled casserole in the preheated oven and bake it for 35-40 minutes. You’ll know it’s ready when the center is set and the top is beautifully golden brown. Once baked, let the casserole cool for about 5 minutes before slicing, allowing the flavors to meld and making it easier to serve.

Storage Tips for Bisquick Breakfast Casserole
Fridge: Store any leftovers in an airtight container for up to 4 days to maintain freshness and flavor.
Freezer: You can freeze the casserole for up to 2 months. Slice it into portions and wrap each piece tightly in plastic wrap before putting it in a freezer-safe bag.
Reheating: To reheat, simply place slices in the oven at 350°F (175°C) for about 15-20 minutes, or until heated through. This helps keep your Bisquick Breakfast Casserole fluffy and delicious!
Make-Ahead: If you’re planning ahead, assemble the casserole the night before and keep it in the fridge until you’re ready to bake, ensuring a hassle-free morning.
Make Ahead Options
These Bisquick Breakfast Casserole is perfect for busy home cooks looking to save time during their mornings! You can prepare the entire casserole up to 24 hours in advance by mixing the batter and assembling all the components—just be sure to keep it covered in the refrigerator to maintain freshness. If you want to prep specific components, you can cook the sausage and chop the veggies up to 3 days ahead, storing them in airtight containers. When you’re ready to bake, simply pour the Bisquick mixture over the prepped ingredients and pop it in the oven. This way, you’ll enjoy a hearty meal without the morning stress, all while keeping that delightful flavor just as delicious as fresh!
