Steps to Make It
- Preheat your oven to 350°F. The warm air will soon fill your kitchen with delicious aromas.
- In a large skillet, cook the sausage over medium heat until browned. Stir it occasionally and enjoy the savory smell wafting through your kitchen.
- Add the diced onion and bell pepper to the skillet. Sauté until the veggies are soft and the onion is translucent, about 5 minutes.
- In a large bowl, whisk together the eggs, milk, salt, pepper, and garlic powder. The mixture should be smooth and creamy.
- Add the cubed bread and cooked sausage mixture to the egg mixture. Stir gently until everything is well combined and the bread is soaked.
- Pour the entire mixture into a greased 9×13-inch baking dish. Spread it out evenly, and top with shredded cheddar cheese.
- Cover the dish with foil and bake for 30 minutes. Then, remove the foil and bake for an additional 15 minutes until the cheese is bubbly and golden brown.
- Let it cool for a few minutes before slicing. The casserole should be set and slightly firm to the touch.
- Serve warm and watch everyone dig in with big smiles!
Make It Perfect
- Use day-old bread for better texture; it soaks up the egg mixture perfectly.
- Feel free to add in any leftover veggies or meats you have on hand.
- Let the casserole sit for a few minutes after baking; it’ll slice better.
- For extra flavor, sprinkle some herbs like thyme or parsley on top before serving.
Mix It Up
- Swap out the cheddar for Swiss or feta cheese for a different flavor.
- Add cooked bacon or ham for a meat lover’s twist.
- Incorporate spinach or kale for a veggie-packed version.
Perfect Partners
- Serve with fresh fruit salad for a refreshing contrast.
- Pair with warm cinnamon rolls for a sweet treat.
- A hot cup of coffee or spiced apple cider makes the perfect beverage.
