This Bisquick Breakfast Casserole is a warm and hearty dish that brings together fluffy eggs, tasty sausage, and cheesy goodness all in one pan. Perfect for breakfast or brunch!
What I love most is how easy it is to whip up—all you do is mix, pour, and bake! It’s a great way to feed a group without spending all morning in the kitchen. 🥳
Key Ingredients & Substitutions
Bisquick Mix: This is the base of our casserole and gives it that fluffy texture. If you don’t have Bisquick, you can make your own with flour, baking powder, and salt, or use another baking mix if you prefer.
Breakfast Sausage: I like using pork sausage for its flavor, but turkey sausage works great if you want a lighter option. For a vegetarian twist, try substituting with cooked veggies or plant-based sausage.
Cheddar Cheese: Cheddar adds a nice sharpness. I prefer using sharp cheddar for more flavor, but feel free to mix it up with mozzarella or pepper jack for some spice. Any shredded cheese will do, so use what you have!
Green Onions: These are optional, but I think they brighten up the dish. If you don’t have them, try parsley or just skip garnishing altogether!
How Do I Ensure My Casserole Is Fluffy and Not Dense?
Getting the right texture in a casserole is all about the mixing and layering!
- Mix your Bisquick, milk, and eggs until just combined—over mixing can make it dense.
- Spread batter evenly in your dish, and then layer your sausage and cheese gently. This keeps everything from sinking.
- Letting it cool for a few minutes after baking before slicing helps it set up nicely.
Take care with your oven time too! Baking just until the middle is set helps ensure a light texture.
Bisquick Breakfast Casserole
Ingredients You’ll Need:
Base Ingredients:
- 3 cups Bisquick mix
- 1 cup milk
- 6 large eggs
- Salt and pepper, to taste
- Butter or cooking spray, for greasing the baking dish
Protein and Cheese:
- 1 pound breakfast sausage (pork or turkey), cooked and crumbled
- 2 cups shredded cheddar cheese
Optional Garnish:
- 1/4 cup chopped chives or green onions
Time Needed:
This comforting casserole takes about 10 minutes to prepare and around 45 minutes to bake, giving you around 55 minutes total from start to delicious finish! It’s perfect for a leisurely weekend brunch or breakfast for a crowd.
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). While it heats, grab a 9×13-inch baking dish and grease it generously with butter or cooking spray to prevent sticking.
2. Mix the Batter:
In a large bowl, whisk together the Bisquick mix, milk, eggs, salt, and pepper until everything is smooth and combined. No lumps please! This will be your base for the casserole.
3. Layer the Ingredients:
Pour half of the batter into the prepared baking dish and spread it out evenly with a spatula. Then, sprinkle the cooked, crumbled sausage over this first layer. Next, sprinkle 1 cup of the shredded cheddar cheese over the sausage to create a cheesy goodness layer!
4. Complete the Casserole Layers:
Now, pour the remaining half of the batter over the sausage and cheese layers, spreading gently to cover everything. Finally, top it all off with the last cup of cheddar cheese for an extra melty and delicious finish!
5. Bake Your Casserole:
Place the baking dish in your preheated oven and let it bake for about 45 minutes. You’ll know it’s ready when the casserole is set in the middle and the cheese is golden and bubbly. It’s going to smell amazing!
6. Let It Cool and Serve:
Once baked, remove the casserole from the oven and let it cool for about 5 minutes before slicing. This allows it to firm up a bit, making it easier to serve. If you’re feeling fancy, garnish with chopped chives or green onions for a pop of color.
7. Enjoy!
Serve warm and enjoy this rich, cheesy breakfast casserole with your favorite sides. It’s perfect on its own or with a light salad or some fresh fruit!
This Bisquick Breakfast Casserole can also be prepped the night before. Just refrigerate it overnight and bake it in the morning for a stress-free breakfast!
Can I Use a Different Type of Cheese?
Absolutely! While cheddar is a classic choice, you can substitute it with mozzarella, pepper jack for some heat, or even a blend of your favorites. Just ensure it’s shredded for easy melting.
Can I Add Vegetables?
Definitely! Feel free to add cooked vegetables like bell peppers, spinach, or mushrooms to the sausage layer for added flavor and nutrition. Just make sure they are cooked and drained before adding, so they don’t release too much moisture into the casserole.
How Can I Make This Vegetarian?
For a vegetarian version, you can substitute the sausage with cooked veggies or vegetarian sausage. You could also add extra cheeses like feta or mozzarella for more flavor!
Can I Freeze Leftover Casserole?
Yes, you can freeze leftovers! Just let the casserole cool completely, then wrap it tightly in foil or plastic wrap and store it in an airtight container. It will keep well for up to 2 months. To reheat, thaw in the fridge overnight and warm it in the oven or microwave.
