Step-by-Step Instructions
Prepping the Oven and Dish
– Preheat your oven to 350°F (175°C).
– Grease a 9×13 inch baking dish with cooking spray or butter. This keeps the casserole from sticking.
Cooking the Sausage
– In a large skillet over medium heat, cook the crumbled sausage until it is browned and hot. This usually takes about 5-7 minutes.
– Once browned, remove the sausage from the heat and set it aside.
Mixing the Egg Mixture
– In a mixing bowl, whisk together 6 large eggs and 2 cups of milk.
– Add in 1 teaspoon each of garlic powder, onion powder, and dried oregano.
– Lastly, mix in 1 teaspoon of salt and ½ teaspoon of black pepper. Whisk until everything is well combined.
Assembling the Casserole
– Spread 4 cups of cubed bread evenly across the bottom of the greased dish.
– Layer the cooked sausage over the bread, followed by 1 cup of diced bell peppers.
– Pour the egg mixture over the layers, making sure it seeps through the bread and covers everything well.
– Sprinkle 2 cups of shredded cheddar cheese on top of the egg mixture.
Baking the Casserole
– Bake in the preheated oven for 30-35 minutes.
– Check for doneness when the egg is set, and the top is golden and bubbly.
Tips & Tricks
Perfecting the Casserole
To get the best texture, choose fresh bread. Stale bread soaks up the egg mixture better. This gives you a soft and fluffy base. Cook the sausage until it’s nicely browned. This adds a deep flavor. Be sure to layer the sausage evenly. It helps every bite taste great.
For even cooking, mix the egg mixture well. Make sure the spices blend fully. Pour it over the layers slowly. This allows the bread to soak up the flavors. Bake until the top is golden and bubbly. This shows the casserole is ready to enjoy.
Ingredient Substitutions
If you want a different flavor, try turkey or chicken sausage. These options are leaner but still tasty. You can also use plant-based sausage for a vegetarian dish. It works well and keeps the meal hearty.
For a dairy-free version, use almond or oat milk. These choices keep the creaminess without dairy. You can also swap out cheese for a nut-based alternative. It adds a nice creaminess without the milk.
Serving Suggestions
This casserole pairs well with fresh fruit. Sliced oranges or berries add a bright touch. You can also serve it with hash browns for a filling breakfast.
For garnishing, sprinkle chopped green onions on top. They add a nice crunch and color. You can also add hot sauce for a spicy kick. This gives an extra layer of flavor.
Pro Tips
- Use Day-Old Bread: Stale bread absorbs the egg mixture better, yielding a firmer texture and preventing sogginess.
- Customize Your Veggies: Feel free to mix in your favorite vegetables like spinach, mushrooms, or zucchini for added flavor and nutrition.
- Make Ahead: Assemble the casserole the night before and refrigerate it. Just pop it in the oven in the morning for an easy breakfast.
- Check for Doneness: Use a toothpick to check the center of the casserole; it should come out clean when fully cooked.
Variations
Different Cheeses
Using different cheeses can change the flavor of your casserole. Cheddar is popular for its sharp taste and meltability. You can try Monterey Jack for a milder flavor or even a blend of cheeses. Mixing cheeses adds depth. For instance, combining cheddar and mozzarella gives a creamy texture and a rich taste. Experiment with your favorites to find the perfect mix.
Seasonal Ingredients
You can enhance your casserole with seasonal veggies. Try adding spinach in spring or zucchini in summer. These vegetables not only add color but also healthy nutrients. For holiday variations, think of adding roasted butternut squash in autumn or festive herbs like sage for Thanksgiving. These small changes can make your casserole feel special for any occasion.
Cooking Methods
If you’re short on time, you can use a slow cooker. Just layer the ingredients and cook on low for 6-8 hours. This method allows the flavors to meld beautifully. You can also use an Instant Pot for quick results. Cook on high pressure for about 20 minutes, then let it naturally release for 10 minutes. Both methods yield tasty casseroles, making it easy to enjoy this dish any time.
Storage Info
Refrigeration
After your cheesy sausage breakfast casserole cools, store it in an airtight container. This keeps it fresh and safe. Place it in the fridge within two hours of baking. Proper cooling helps avoid bacteria growth.
Freezing Guidelines
To freeze leftovers, cut the casserole into portions. Wrap each piece in plastic wrap and place it in a freezer bag. Use a marker to label it with the date. This way, you know when to eat it. For reheating, thaw the casserole overnight in the fridge. Then, bake at 350°F (175°C) for about 20 minutes. This warms it through and keeps it tasty.
Shelf Life
In the fridge, your casserole lasts about three to four days. Check for signs of spoilage before eating. If it looks dry or has an off smell, it’s best to toss it. Always trust your senses; they guide you well.
