Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
- 1 lb breakfast sausage (turkey or halal sausage)
- 1 can (16 oz) refrigerated biscuit dough
- 6 large eggs
- 1/2 cup milk
- 1 1/2 cups shredded cheddar cheese
- Salt and pepper to taste
- Optional: chopped green onions or parsley for garnish
How to Make It Step-by-Step
Making this Sausage Egg Biscuit Casserole is a breeze, and the result is a rich, cheesy masterpiece that will have everyone asking for seconds.
- Preheat the Oven: Start by preheating your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish, or use non-stick spray for an easy cleanup.
- Cook the Sausage: In a large skillet over medium heat, crumble and cook your breakfast sausage until it’s fully browned and cooked through. If you’re using turkey sausage or halal sausage, it will still give you that hearty, savory flavor you love. Drain any excess grease and set the sausage aside.
- Cut and Layer the Biscuits: Take your refrigerated biscuit dough and cut each biscuit into quarters. Spread the pieces evenly across the bottom of the greased baking dish. No need to pre-cook the biscuits—they’ll bake right into the casserole!
- Add the Sausage and Cheese: Sprinkle the cooked sausage over the biscuit pieces, followed by a generous layer of shredded cheddar cheese.
- Whisk the Eggs: In a mixing bowl, whisk together the eggs, milk, salt, and pepper. Pour this egg mixture evenly over the sausage and biscuit layers in the baking dish. The eggs will soak into the biscuits, creating a soft, fluffy base.
- Bake the Casserole: Place the dish in the preheated oven and bake for 35–40 minutes, or until the eggs are fully set and the top is golden brown. You can test for doneness by inserting a knife into the center—it should come out clean when the casserole is done.
- Cool and Serve: Once it’s baked to perfection, let the casserole rest for a few minutes before slicing. If you want to add a fresh touch, sprinkle with chopped green onions or parsley for a pop of color and flavor.
Tips for Best Results
- Use Quality Sausage: Whether you’re using turkey sausage, halal sausage, or pork sausage, make sure it’s flavorful and high-quality. The sausage is the star of the dish, so you want to get it just right.
- Add a Kick: If you like a bit of heat, opt for spicy sausage or sprinkle some crushed red pepper flakes or fresh jalapeños into the mix.
- Don’t Overbake: Keep an eye on your casserole as it bakes. If you overbake it, the eggs can become dry, so check for doneness during the last 5–10 minutes of baking.
- Keep it Moist: If you’re worried about the casserole drying out, you can cover it loosely with foil for the first 20 minutes of baking and then uncover it for the rest of the time.
Ingredient Substitutions & Variations
This casserole is super adaptable, and you can easily make it your own based on your dietary preferences or what you have available. Here are some ideas:
- Spicy Version: Use hot sausage, or add a sprinkle of red pepper flakes or diced jalapeños for some extra spice.
- Veggie Add-In: Toss in sautéed bell peppers, spinach, or mushrooms for added veggies. You could even throw in a few chopped tomatoes for extra freshness.
- Different Cheese: While cheddar is classic, feel free to experiment with different cheeses like mozzarella, pepper jack, or Colby cheese for a unique twist.
- Gravy Topping: For a more indulgent dish, serve the casserole with a drizzle of homemade sausage gravy.
- Mini Casseroles: If you’re serving a crowd or need a portable option, bake this casserole in muffin tins for individual servings.
Serving Suggestions
This Sausage Egg Biscuit Casserole is a meal on its own, but it’s also great paired with a few simple sides. Here are some ideas to round out your breakfast:
- Fresh Fruit: Serve with a side of fresh fruit like berries, sliced melon, or citrus slices to balance the richness of the casserole.
- Coffee or Fresh Juice: Pair this hearty breakfast with a cup of coffee, or for a lighter touch, serve with freshly squeezed orange juice or a smoothie.
- Crispy Hash Browns: If you’re craving something extra crispy, add a side of crispy hash browns or roasted potatoes.
- Avocado Toast: For a healthy and trendy addition, serve with avocado toast for a creamy, nutritious side.
How to Store and Reheat Leftovers
This casserole is a great high-protein pre-made meal for the week ahead! Here’s how to store and reheat leftovers:
- Storage: Store any leftovers in an airtight container in the refrigerator for up to 4 days.
- Reheating: Reheat individual servings in the microwave for 30–60 seconds, or place them in the oven at 325°F until warmed through. The casserole stays moist and flavorful, even when reheated!
Make-Ahead and Freezer Tips
- Make-Ahead: You can assemble the casserole the night before and refrigerate it overnight. Just bake it fresh in the morning for an easy, no-hassle breakfast.
- Freezer-Friendly: To freeze, bake the casserole, let it cool completely, and then slice and store it in freezer-safe containers. It will keep in the freezer for up to 3 months. Reheat in the oven or microwave for a quick breakfast.
Common Mistakes to Avoid
- Overbaking: The biggest mistake you can make is overbaking the casserole. Keep an eye on it to ensure the eggs don’t dry out.
- Using Too Much Sausage: Sausage is flavorful, but too much can overwhelm the other ingredients. Stick to the recommended amount for the best balance.
- Skipping the Resting Time: Let the casserole rest for a few minutes after baking before slicing. This helps the layers set and prevents it from falling apart.
