Ingredients
To make the Bisquick Breakfast Casserole, gather the following ingredients:
- 1 pound (450 g) beef breakfast sausage or chicken/turkey sausage
- 1 bell pepper (red, yellow, or orange), diced
- 1 small yellow onion, diced
- 1 ½ cups frozen shredded hash browns
- 2 cups shredded cheddar cheese, divided
- 1 ½ cups Bisquick baking mix
- 4 large eggs
- 2 cups (480 ml) whole milk
- ¼ teaspoon ground black pepper
- Salt to taste
How To Make Bisquick Breakfast Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C).
This ensures that the casserole will cook evenly and achieve that golden-brown top we all love.
Step 2: Cook the Sausage
In a large skillet over medium heat, cook the sausage until it’s browned and fully cooked, breaking it up into small pieces as it cooks.
If you’re using a leaner turkey or chicken sausage, make sure it’s properly browned for the best flavor.
Step 3: Add the Vegetables
Once the sausage is cooked, stir in the diced bell pepper and onion.
Sauté for about 3-4 minutes, until the vegetables are slightly softened and fragrant.
Step 4: Combine the Ingredients
In a large bowl, whisk together the Bisquick baking mix, milk, and eggs until smooth.
Stir in the cooked sausage mixture, frozen hash browns, and 1 cup of the shredded cheddar cheese.
Season with ground black pepper and salt to taste.
Step 5: Pour into Baking Dish
Grease a 9×13-inch baking dish and pour the mixture into it evenly.
Sprinkle the remaining 1 cup of shredded cheddar cheese on top for that irresistible cheesy layer.
Step 6: Bake
Bake in the preheated oven for 35-40 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Step 7: Cool and Serve
Once baked, let the casserole cool for about 5-10 minutes before slicing.
Serve warm and enjoy a delicious breakfast that will keep you satisfied!
Expert Tips
- For extra flavor, consider adding spices like paprika or cayenne pepper to the sausage while cooking.

Variations and Customizations
- Swap the cheddar cheese for other varieties like Monterey Jack, mozzarella, or pepper jack for a twist.
