How to Make Breakfast Casserole

Step 1: Preheat the Oven

• Preheat your oven to 375°F (190°C).
• Lightly grease a 9×13-inch casserole dish with cooking spray or butter to prevent sticking.

Step 2: Prepare the Biscuit Base

1. Open the can of Grands Biscuits and separate the biscuits. Cut each biscuit into quarters for easier layering.
2. Arrange the biscuit pieces evenly across the bottom of the greased casserole dish.

Step 3: Add the Sausage

1. If using precooked sausage crumbles, skip ahead to step 2. Otherwise, cook the sausage in a skillet over medium heat, breaking it into crumbles with a spoon, until no longer pink. Drain any excess grease.
2. Evenly sprinkle the sausage crumbles over the biscuit layer in the casserole dish.

Step 4: Add the Cheese

1. Sprinkle the shredded mozzarella and cheddar cheese over the sausage layer, spreading it evenly.
2. Feel free to use more cheese if you like your casserole extra cheesy.

Step 5: Mix the Egg Mixture

1. In a medium mixing bowl, whisk together the beaten eggs, milk, salt, and pepper.
2. If using optional veggies (like sautéed spinach, mushrooms, or red peppers), fold them into the egg mixture.

Step 6: Pour the Egg Mixture

1. Slowly pour the egg mixture evenly over the layered biscuits, sausage, and cheese.
2. Use a spatula or spoon to gently press down on the layers, ensuring everything is coated.

Step 7: Bake the Casserole

1. Place the casserole in the preheated oven and bake for 25–30 minutes, or until the eggs are fully set and the top is golden brown.
2. To check doneness, insert a knife or toothpick into the center—it should come out clean.

Step 8: Cool and Serve

1. Allow the casserole to cool for about 5 minutes before slicing into squares.
2. Serve warm with your favorite toppings like green onions, salsa, sour cream, or hot sauce.

Tips for the Best Breakfast Casserole

1. Room Temperature Ingredients: Using room-temperature eggs and milk ensures even mixing and cooking.
2. Partially Cook Biscuits: To prevent undercooked dough, partially bake the biscuits before adding the toppings.
3. Add Veggies: Sautéed spinach, mushrooms, or red peppers make great additions for extra nutrients.
4. Customize the Cheese: Use Pepper Jack, Colby Jack, or your favorite cheese blend for added flavor.
5. Check for Doneness: Test the center of the casserole to ensure the eggs are fully set before removing from the oven.

Flavor Variations and Substitutions

• Meat Options: Swap the sausage for turkey sausage, chicken sausage, bacon, or even chorizo for a spicy kick.
• Vegetarian: Skip the meat and load up on veggies like zucchini, tomatoes, or kale.
• Spicy Kick: Add diced jalapeños, a sprinkle of cayenne, or a drizzle of hot sauce for heat.
• Gluten-Free: Use gluten-free biscuits or omit the biscuit layer entirely for a crustless version.
• Extra Toppings: Add crushed tortilla chips, avocado slices, or fresh pico de gallo for a Tex-Mex twist.

5. Overcooking: Check the casserole at the 25-minute mark to prevent dry or overcooked eggs.
