Key Ingredients & Substitutions
Bisquick Baking Mix: This is the base of our casserole. If you don’t have it, you can substitute with an equal amount of all-purpose flour, baking powder, and a pinch of salt. Mix 1 cup of flour with 1.5 teaspoons of baking powder and a little salt for a homemade version.
Cheddar Cheese: While sharp cheddar is delicious, feel free to mix it up! Use pepper jack for some heat or mozzarella for a milder taste. Don’t hesitate to experiment with a blend of your favorite cheeses!
Breakfast Sausage: If you prefer a leaner option, turkey sausage works great. For a vegetarian version, try adding sautéed vegetables like bell peppers and spinach instead, or use meat alternatives available in stores.
Bacon: Use turkey bacon or skip it altogether for a lighter option. For a twist, try using cooked ham or crumbled cooked chorizo to add a different flavor profile!
How Do I Ensure My Casserole is Perfectly Cooked?
The baking time is crucial for a well-cooked casserole. Start by preheating your oven fully to ensure even baking. Here’s what to keep in mind:
- Check the casserole at around 40 minutes. If it’s golden brown on top and a toothpick comes out clean, it’s ready to go!
- Let it cool for about 5-10 minutes before cutting. This helps it set up a bit more and makes serving easier.
- If it’s still jiggly in the center, pop it back in the oven for a few more minutes, checking often.
These tips will help you achieve a delicious and satisfying Bisquick Breakfast Casserole. Happy cooking!

7. Cool and Cut:
Once out of the oven, allow the casserole to cool slightly for about 5-10 minutes. This will make it easier to cut into squares.

Can I Use Frozen Ingredients in This Recipe?
Yes, you can use frozen ingredients! If you want to add frozen vegetables, just make sure to thaw and drain them before mixing them in. For the breakfast sausage, cook it from frozen, but it may require a few extra minutes to ensure it’s completely cooked through.
Can I Make This Casserole Ahead of Time?
Absolutely! You can prepare the casserole the night before. Simply assemble it, cover it tightly with plastic wrap, and place it in the fridge. When you’re ready to bake, remove it from the fridge and let it sit at room temperature for about 20 minutes before baking as instructed.
How Should I Store Leftovers?
Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. To reheat, simply pop individual portions in the microwave for a quick breakfast, or warm it up in the oven at 350°F (175°C) until heated through.
Can I Customize the Ingredients?
Yes, feel free to customize the casserole! You can substitute different cheeses, add veggies like spinach or bell peppers, or use ham instead of sausage. Just keep the proportions similar to maintain the casserole consistency!
