biscuit dough I used canned, refrigerated biscuits, Pillsbury Grands. Store brand or another brand works fine too.

How To Make Breakfast Biscuit Casserole

Preheat the oven to 350 degrees. Spray a 9 x 13-inch baking dish with spray cooking oil.
Place a large skillet over medium-high heat. Add the breakfast sausage, breaking it into pieces and stirring it as it cooks. Brown until fully cooked and their is no more pink. Drain any excess fat and set the sausage to the side.

Let the casserole rest for a few minutes before cutting, then add sliced green onions as garnish if desired. Cut into squares, serve and enjoy hot!

Breakfast Casserole With Biscuits Variation Ideas

Swap The Meat – Crumbling cooked bacon in place of half or all of the sausage is the most obvious easy switch to me in the breakfast casserole. Diced ham, even if it’s thinly slice lunchmeat also works, but you may want to crisp it up in a pan before adding it. Leftover diced cooked chicken is another great way to clean out the fridge with this breakfast casserole recipe.

Chorizo is another delicious option, and is especially delicious with a few ounces of chopped of green chiles if that’s your style.

Add Vegetables – You can add vegetables like onion, bell pepper, asparagus sliced into 1 inch pieces, bite sized pieces of broccoli, sliced cherry tomatoes, or corn. Spinach, kale, or frozen veggies are fine to add but are more watery and need to be sauteed in the pan first to get the water out or they can make the casserole too watery. Adding between 1/2- 3/4 cup of vegetables total to this recipe usually works best to keep the bake time similar and not overwhelm the casserole with too many veggies.

Try Different Cheeses – Pretty much any shredded cheese works well in this recipe, try cheddar, provolone, pepper jack, or even a blend.
