How to Make Italian Sausage Biscuit Casserole
Making this casserole is simple and easy.
First, cook the sausage, bell peppers, and carrots in a skillet over medium heat. Break the sausage up using a spatula or my favorite meat chopper (if you don’t have one you need it!) and cook it through. Remove any excess grease from the pan by blotting the pan with a paper towel.
Next, add the diced tomatoes, tomato sauce, cheese, and salt and pepper to the meat mixture and stir. Let that simmer away for five minutes, stirring occasionally.
Prepare a 9×13 baking dish by spraying it with nonstick spray. Pour the casserole mixture into the baking dish and spread it out.

Open the biscuits and peel each biscuit into two to create twice as many biscuits. This will make them quite a bit thinner. Place the biscuits on top of the casserole next to each other, overlapping a bit. Drizzle the butter over the top then sprinkle the garlic salt and oregano on top as well.
Bake for about half an hour, or until the biscuits are all the way cooked through and golden brown on top. Serve and enjoy!

Recipe Notes
- If you want to half this recipe, you can bake it in an 8×8 pan. Just divide all the ingredients by half, including the biscuits. If you only use half of the biscuits, turn the other half into delicious Cinnamon Roll Biscuits!
- Use your favorite brand of canned biscuits. I always use Pillsbury Grands because I like the buttery flavor and how light and airy they bake up.
- Use any other ground meat in place of the Italian sausage. You might just need to add a little extra salt and pepper.
