This cheesy sausage breakfast casserole is a warm and hearty dish that’s perfect for starting your day right! With layers of sausages, eggs, and plenty of melted cheese, it’s breakfast bliss.
Making this casserole is super easy—just mix everything up, pour it in a dish, and let the oven do the work. I love serving it with some fruit on the side for a little sweetness!
Key Ingredients & Substitutions
Breakfast Sausage: The star of this dish! If you’re looking for a lighter option, turkey or chicken sausage works well as a substitute. If you prefer a vegetarian twist, try using plant-based sausage or mushrooms for flavor.
Red Bell Pepper: Adds sweetness and color. You can substitute with any bell pepper, or even zucchini or spinach if you want to sneak in some greens!
Onion: I used a small onion here, but you can easily swap for shallots for a milder taste or green onions for a fresh kick.
Cheese: Cheddar is a classic choice. For a different flavor, try using Monterey Jack or Pepper Jack for some spice. Vegan cheese also works if you’re looking for dairy-free options!
Milk: Whole milk gives richness, but you can substitute with low-fat milk, almond milk, or any non-dairy milk you prefer.
How Do I Ensure My Casserole Is Perfectly Cooked?
Cooking time is crucial. To make sure your casserole is cooked through, look for these signs:
- The edges should be firm, and there should be no jiggling in the center.
- The top should be golden brown and slightly crispy.
- Letting it cool for 5-10 minutes before slicing allows it to firm up further, making serving easier.
Using an oven thermometer can help ensure your oven is at the right temperature, avoiding undercooked or overcooked spots! Enjoy your delicious breakfast casserole!
Cheesy Sausage Breakfast Casserole
Ingredients:
- 1 pound breakfast sausage (bulk or removed from casings)
- 1 small red bell pepper, diced
- 1/2 small onion, diced
- 8 large eggs
- 1 cup whole milk
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 2 cups shredded cheddar cheese
- 1/4 cup chopped fresh parsley (optional, for garnish)
- Cooking spray or butter (for greasing the baking dish)
Time Needed:
This delicious breakfast casserole requires about 10 minutes to prepare and 35 to 40 minutes to bake. In total, you’re looking at around 50 minutes from start to finish, making it a great option for a hearty morning meal or brunch gathering!
Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This ensures that your casserole cooks evenly and thoroughly. While it’s heating, lightly grease a 9×13 inch baking dish with cooking spray or butter to prevent sticking.
2. Cook the Sausage:
In a skillet over medium heat, add the breakfast sausage. Cook it until browned and fully cooked through, breaking it up into small pieces. If there’s excess fat, drain it off so your casserole isn’t greasy.
3. Add Vegetables:
Now, toss the diced red bell pepper and onion into the skillet with the sausage. Cook them together for about 3-4 minutes until the veggies are softened. Once done, remove the skillet from the heat and set aside.
4. Prepare the Egg Mixture:
In a large mixing bowl, whisk together the eggs, milk, salt, and black pepper until everything is well combined. This mix will form the base of your casserole.
5. Combine Mixtures:
Next, stir the cooked sausage and vegetable mixture into the egg mixture, ensuring everything is evenly distributed and coated.
6. Layer the Casserole:
Pour half of the sausage and egg mixture into the prepared baking dish. Then, sprinkle 1 cup of shredded cheddar cheese evenly over this layer. Pour the remaining sausage and egg mixture on top, spreading it out gently. Finally, top it off with the last cup of cheddar cheese.
7. Bake the Casserole:
Place the casserole in the preheated oven and bake uncovered for 35 to 40 minutes. You’ll know it’s ready when the center is set (no jiggle) and the top is golden brown and bubbly.
8. Cool and Garnish:
Once baked, remove the casserole from the oven and let it cool for about 5-10 minutes. This cooling time helps it firm up a bit, making it easier to slice. If desired, sprinkle with chopped fresh parsley for a pop of color and flavor!
9. Serve Warm:
Slice the casserole into squares and serve warm. It pairs wonderfully with fresh fruit or a light salad for a complete meal!
This hearty casserole delivers a wonderful blend of flavors and textures, making it an ideal dish for any breakfast or brunch occasion!
Can I Use Different Types of Sausage?
Absolutely! You can use turkey sausage for a leaner option, or even chicken sausage if you prefer. For a vegetarian version, swap out the sausage for veggies or a plant-based sausage alternative.
Can I Make This Casserole Ahead of Time?
Yes, you can prepare the casserole the night before! Just assemble it without baking, cover it tightly in the fridge, and bake it the next morning. You might need to add a few extra minutes to the baking time if it’s cold from the fridge.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, simply warm it up in the microwave or pop it back in the oven at 350°F (175°C) until heated through.
Can I Freeze This Casserole?
Yes, you can freeze the unbaked casserole! Just cover it tightly with plastic wrap and foil, or place it in a freezer-safe container. When you’re ready to bake, let it thaw overnight in the fridge and then bake as directed. It can also be frozen after baking, but be sure to let it cool completely before freezing!
