Key Ingredients & Substitutions
Breakfast Sausage: You can go for mild or spicy sausage based on your taste buds! If you’re looking for a lighter option, turkey sausage works well as a substitute, or even plant-based sausage for a vegetarian twist.
Eggs: Large eggs are best here, but if you need an egg substitute, use 1/4 cup of unsweetened applesauce or 1/4 cup of silken tofu per egg. Keep in mind this may change the texture a bit.
Milk: Whole milk provides creaminess, but you can use 2% milk or even almond milk to make it lighter. Just ensure the almond milk is unsweetened to avoid any odd flavors.
Bread Cubes: Day-old bread is ideal because it’s drier and soaks up the egg mixture better. Any bread works including sourdough, whole grain, or even croissants for a rich taste. Just make sure it’s cut into cubes!
Cheddar Cheese: Sharp cheddar adds a strong flavor, but you can mix it up with Monterey Jack, Gruyère, or even a blend of cheeses if you like. For a dairy-free option, there are some great plant-based cheeses available.
How Do You Ensure the Perfect Casserole Texture?
The key to a fluffy and well-set casserole lies in how you prepare and layer your ingredients. Here’s how to do it right:
- Cook the sausage: Make sure it’s fully cooked and crumbled small, so it mixes well with the bread.
- Soak the bread: Let the bread cubes sit in the egg mixture for a few minutes. This ensures they absorb enough liquid.
- Watch the bake time: Start with the cover to let it cook through, then remove it to brown the top. Keep an eye on it to prevent burning.
- Let it rest: Allow the casserole to sit after baking. This helps it firm up a bit, making it easier to cut into squares.
If you follow these tips, you’ll have a delicious casserole that’s crispy on top and soft inside!
How to Make Cheesy Sausage Breakfast Casserole
Ingredients You’ll Need:
For the Casserole:
- 1 lb breakfast sausage (mild or spicy, according to preference)
- 8 large eggs
- 2 cups whole milk
- 6 cups bread cubes (preferably day-old or slightly toasted)
- 2 cups shredded sharp cheddar cheese (divided)
- 1 small red bell pepper, finely diced (optional, for color and flavor)
- 1/4 cup green onions, chopped (optional)
- 1 tsp salt
- 1/2 tsp black pepper
- 1 tsp garlic powder
- 1/2 tsp dried oregano or Italian seasoning
- Fresh parsley, chopped (for garnish)
How Much Time Will You Need?
This cheesy breakfast casserole will take about 15 minutes of prep time and 50 minutes of baking time, bringing your total to about 1 hour and 5 minutes. Perfect for a delicious brunch or make-ahead breakfast for busy weekdays!
Step-by-Step Instructions:
1. Preheat the Oven:
First, set your oven to preheat at 350°F (175°C). While it warms up, take a moment to lightly grease a 9×13-inch baking dish so nothing sticks later.
2. Cook the Sausage:
In a large skillet over medium heat, add the breakfast sausage. Cook it until it’s browned and fully cooked through, breaking it into small crumbles as it cooks. Once done, drain any excess grease and set the sausage aside.
3. Sauté the Bell Pepper:
If you’ve decided to add the bell pepper, toss the diced pieces into the same skillet with the sausage drippings. Sauté them for about 2-3 minutes, until they soften a bit. Remove from heat and set aside.
4. Prepare the Egg Mixture:
In a large mixing bowl, whisk together the eggs, whole milk, salt, black pepper, garlic powder, and oregano until everything is well combined and smooth.
5. Combine Ingredients:
Add the bread cubes, cooked sausage, sautéed bell pepper (if you’re using it), 1 1/2 cups of the shredded cheddar cheese, and chopped green onions (if using) into the egg mixture. Gently stir everything together, making sure the bread absorbs some of that lovely egg mixture.
6. Transfer to Baking Dish:
Pour the mixed ingredients into the prepared baking dish and spread them evenly. Don’t worry if it looks a bit lumpy; that’s how it should be!
7. Add Cheese on Top:
Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top of the casserole.
8. Bake Initially Covered:
Cover the baking dish with aluminum foil and pop it into the oven. Bake for 30 minutes for the casserole to cook through and set.
9. Finish Baking:
After 30 minutes, take off the foil and bake for an additional 15-20 minutes until the top is golden brown and set—poke a knife in to check; it should come out clean!
10. Let It Rest:
Once it’s done, remove the casserole from the oven and let it sit for about 5-10 minutes before cutting it into squares. This resting time helps it firm up a bit.
11. Garnish and Serve:
Before serving, sprinkle some chopped fresh parsley on top to add a touch of color and flavor. Enjoy your hearty and cheesy breakfast casserole!
This dish is perfect for brunch gatherings or as a make-ahead breakfast option to brighten your mornings. Serve it warm and watch everyone go back for seconds!
Can I Use Different Types of Sausage in This Recipe?
Absolutely! You can use any type of breakfast sausage that you prefer, such as turkey, chicken, or even plant-based sausage for a vegetarian option. Just cook it the same way as described.
Can I Prepare This Casserole the Night Before?
Yes, you can prepare the casserole the night before! Just follow all the steps up until pouring it into the baking dish. Cover and refrigerate overnight, and bake it in the morning. You may need to add a few extra minutes to the baking time since it will be chilled.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, you can warm individual portions in the microwave or reheat the whole casserole in the oven at 350°F (175°C) until heated through.
Can I Add Other Vegetables?
Definitely! You can add other vegetables like spinach, mushrooms, or zucchini for extra flavor and nutrition. Just sauté them as you would the bell pepper before mixing them into the casserole.
