How To Make the Make Ahead Biscuit Breakfast Casserole

Step 1: Cook the Sausage

Brown the breakfast sausage in a skillet over medium heat until fully cooked, breaking it into crumbles as it cooks. Drain any excess grease and set aside to cool slightly.

Step 2: Prepare the Biscuit Base

Cut the refrigerated biscuit dough into bite sized pieces and spread them evenly in a greased baking dish. This creates the base layer that will absorb all the flavor.

Step 3: Mix the Egg Mixture

In a large bowl whisk together eggs, milk, salt, pepper, and garlic powder until smooth and well combined.

Step 4: Assemble the Casserole

Scatter the cooked sausage over the biscuit pieces, then sprinkle shredded cheddar cheese and green onions on top. Pour the egg mixture evenly over everything so it soaks into all the layers.

Step 5: Chill Overnight

Cover the dish tightly and refrigerate for at least 6 hours or overnight. This step allows the biscuits to absorb the liquid and ensures even baking.

Step 6: Bake Until Golden

Remove the casserole from the fridge while the oven preheats to 350°F. Bake uncovered for 35 to 45 minutes until the center is set and the top is lightly golden.
