Ingredients needed
Bisquick – You can typically find a box of Originial Bisquick mix in the baking aisle of the grocery store.
Sausage – Breakfast sausage is used for this recipe. We are using a pound of original Jimmy Dean sausage but sage, spicy sausage, or even the maple flavored would also be delicious.
Eggs – 4 large eggs.
Milk – You can use 2% or whole milk for this recipe. Whole milk will give it a richer flavor.
Bell Peppers – This ingredient is optional but it adds nice color and flavor. We are using red bell pepper but feel free to use your favorite color.
Onion – White or sweet Vadalia onion.
Hash Browns – Frozen shredded hash browns are needed. They don’t need to be thawed.
Shredded Cheese – I am using a mild cheddar cheese. Sharp cheddar, cheddar blend, or even Colby Jack will work great.
Seasonings – Salt and ground black pepper
How to make Bisquick Breakfast Casserole
Step one: Preheat oven to 375 degrees F. Start by cooking the breakfast sausage in a large skillet. You will want to crumble it up and cook until browned. Discard the excess grease and then add pepper and onion. Cook another 2-3 minutes to soften.
Step two: Spray a 9 x 13 casserole dish with nonstick cooking spray. Add cooked sausage mixture, hash browns, and half of the cheese into the prepared baking dish. Stir the ingredients.
Step three: In a large bowl, whisk together eggs, milk, Bisquick, salt and pepper. Pour the egg mixture over the sausage mixture. Bake for 40-45 minutes or until the top starts to turn golden brown.
Step four: Top the casserole with remaining cheese. Bake for another 2-3 minutes or until cheese melts. Make sure to let it sit for about 5 minutes before slicing into pieces.
