Ingredients
- 1 (16.3-ounce) can Grands Biscuits (8 count)
- 1 (8-ounce) package Jimmy Dean precooked sausage crumbles (or 1 cup crumbled cooked sausage)
- 1 cup shredded mozzarella cheese
- 1 cup shredded cheddar cheese (mild or sharp)
- 8 large eggs, beaten (room temperature)

Instructions
- Step 1: Preheat your oven to 375°F (190°C).

- Step 3: Open the can of biscuits and cut each biscuit into quarters.
- Step 4: Arrange the biscuit pieces evenly across the bottom of the greased casserole dish.
- Step 5: If using raw sausage, cook it in a skillet over medium heat until fully browned, breaking it into crumbles. Drain any excess grease.
- Step 6: Spread the precooked or freshly cooked sausage evenly over the biscuit layer.
- Step 7: Sprinkle the shredded mozzarella and cheddar cheese evenly over the sausage layer.

- Step 12: Bake the casserole in the preheated oven for 25–30 minutes, or until the eggs are set and the top is golden brown.
- Step 13: Check doneness by inserting a toothpick or knife into the center; it should come out clean.
- Step 14: Allow the casserole to rest for 5 minutes to set before slicing into squares.
- Step 15: Serve warm and add your favorite toppings like green onions, salsa, sour cream, or hot sauce.
Tips & Variations
- Use whole milk or 2% for a creamy texture, but skim milk works if you want a lighter dish.
- Add sautéed vegetables like spinach, mushrooms, or bell peppers to boost nutrition and flavor.
- Substitute sausage with cooked bacon or diced ham for a different take.
- Let the casserole sit for a few minutes after baking to make slicing easier and cleaner.

Notes
- You can substitute the Jimmy Dean sausage crumbles with any precooked sausage or homemade crumbled cooked sausage.
- For a vegetarian version, omit the sausage and add more sautéed vegetables like bell peppers, mushrooms, or zucchini.
- Allowing the egg mixture to come to room temperature prevents curdling and promotes even baking.
- Use full-fat milk or 2% milk for a richer texture; skim milk may result in a less creamy casserole.
- Leftovers store well in the refrigerator for 3-4 days and can be reheated in the oven or microwave.
- You can prepare the casserole the night before and refrigerate it, then bake it fresh in the morning.
