Step-by-Step Instructions

Creating this easy sausage biscuit breakfast casserole is simple and beginner-friendly. Whether you’re prepping it for a family brunch or your weekly meal prep, follow these straightforward steps for a perfect bake every time.

1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter, oil, or non-stick spray to prevent sticking.
2. Prepare the biscuit base
   • Open the refrigerated biscuit dough and cut each biscuit into quarters.
   • Spread the biscuit pieces evenly across the bottom of your greased baking dish.
   • These biscuits will puff up and form a fluffy base as they bake. You can learn more about the science of baking by checking out these oven baking tips.
3. Layer the sausage
   • Crumble and cook your beef sausage in a skillet until browned. Drain any excess grease.
   • Spread the cooked sausage evenly over the biscuit pieces. This step ensures every bite gets that savory, meaty flavor.
4. Whisk the egg mixture
   • In a medium bowl, combine the eggs, milk, garlic powder, salt, and pepper.
   • Whisk until fully blended. This mixture will set into a creamy, custard-like layer during baking.
5. Pour over the biscuit and sausage layers
   • Pour the egg mixture evenly over the dish, covering all the biscuit and sausage pieces. Let it sit for a couple of minutes so the biscuit dough begins to soak up the liquid.
6. Add cheese and toppings
   • Sprinkle the shredded cheddar and mozzarella cheeses over the top.
   • Add the chopped green onions, if using, for an extra pop of flavor and color.
7. Bake for 30–35 minutes
   • Bake until the eggs are set and the top is golden brown.
   • Check for doneness by inserting a knife or toothpick in the center—it should come out clean.
8. Cool and serve
   • Let the casserole rest for about 5 minutes before slicing. This helps it set and makes serving cleaner and easier.
