Steps to Make It
- Preheat your oven to 350°F. The warmth will set the stage for a cozy breakfast.
- In a large skillet, brown the crumbled sausage over medium heat. Let it cook until it’s golden and fragrant, about 5-7 minutes.
- Add the diced onion and red bell pepper to the skillet. Sauté until the veggies are soft and the onion is translucent, around 3-4 minutes.
- In a large bowl, whisk together the eggs, milk, garlic powder, salt, and black pepper. This mixture should be smooth and creamy.
- Stir in the cubed bread and the sausage mixture into the egg mixture. Make sure everything is well combined and the bread is soaked.
- Fold in the shredded cheddar cheese, and then pour the entire mixture into a greased 9×13 inch baking dish. Spread it evenly.
- Bake in the preheated oven for 30-35 minutes. You’ll know it’s done when the top is golden and a toothpick comes out clean.
- Let it cool for a few minutes before slicing. The smell will be irresistible!
- Serve warm and watch your family dig in with smiles on their faces. Enjoy every magical bite!
- Store any leftovers in an airtight container in the fridge.
Make It Perfect
- Use stale bread for a better texture; it absorbs the egg mixture nicely.
- Feel free to add your favorite veggies like spinach or mushrooms for extra nutrition.
- For a spicy kick, add some diced jalapeños or hot sauce to the mixture.
- Make sure to grease your baking dish well to prevent sticking.
- Let the casserole rest for a few minutes before serving for easier slicing.
Mix It Up
- Add cooked bacon or ham for a meaty twist.
- Mix in some spinach and feta for a Mediterranean flair.
- Top with fresh herbs like parsley or chives for a pop of color and flavor.
Perfect Partners
