Steps to Make It
- Preheat your oven to 350°F. The anticipation will build as the temperature rises, filling your kitchen with warmth.
- In a large skillet, cook the breakfast sausage over medium heat until browned. The sizzling sound and savory smell will make your mouth water.
- Add the diced onion and red bell pepper to the skillet. Sauté until the vegetables are tender and fragrant, about 5 minutes.
- In a bowl, whisk together the eggs, milk, salt, and pepper until well combined. The mixture should look smooth and creamy.
- Cut the refrigerated biscuits into quarters and gently fold them into the egg mixture. This step adds a delightful fluffiness to your casserole.
- Spray a 9×13 inch baking dish with cooking spray. Pour the sausage and vegetable mixture evenly into the dish, then pour the egg and biscuit mixture on top.
- Sprinkle the shredded cheddar cheese over the top. The cheese will melt beautifully, creating a golden crust.
- Bake in the preheated oven for 30 minutes, or until the casserole is set and the top is golden brown. You’ll know it’s done when it puffs up and looks irresistible.
- Let it cool for a few minutes before serving. This will help the casserole set and make it easier to cut.
Make It Perfect
- For a creamier texture, add a splash of heavy cream to the egg mixture.
- Make sure to let the casserole rest before serving to avoid it falling apart.
- Experiment with different cheeses like mozzarella or feta for unique flavors.
- Add cooked spinach or mushrooms for extra veggies and nutrition.
- If you’re short on time, use pre-cooked sausage to speed up the process.
Mix It Up
- Add diced ham for a heartier dish.
- Incorporate fresh herbs like parsley or chives for a fresh flavor.
- Use different types of bread instead of biscuits, like croissants or sourdough.
Perfect Partners
- Serve with fresh fruit for a refreshing contrast.
- Pair with a warm cup of coffee or hot cocoa to complete the meal.
- Add a side of crispy bacon for a classic breakfast touch.
