1-Preheat your oven: Creating Bubble Up Breakfast Casserole is straightforward and fun, perfect for home cooks and students alike. Start by preheating your oven to 350°F (175°C) and lightly greasing a 9×13-inch baking pan to avoid any sticking. This easy process takes about 10 minutes of prep, leading to a delicious meal ready in under 45 minutes total.

2-Prepare the biscuit layer: Next, quarter the refrigerated biscuits without flattening them and spread them evenly in the prepared pan. Layer on the cooked sausage, cubed processed cheese, and shredded mozzarella for a hearty base. In a separate bowl, whisk together the eggs, milk, garlic powder, salt, and pepper until well combined, then pour this mixture over the layers to let it soak in.

3-Bake the casserole: Bake the casserole uncovered for 30 to 45 minutes until it’s golden brown and set. Let it cool for 5 to 10 minutes before serving to make slicing easier.
