Starting your day with a hearty breakfast sets a positive tone for the hours ahead. This breakfast casserole recipe is perfect for an 8-inch pan, offering a satisfying, easy-to-make dish that can be prepared ahead of time and baked fresh in the morning. Its versatile ingredients and straightforward steps make it ideal for weekend brunches, holiday mornings, or a quick family breakfast.
Ingredients
- 6 large eggs
- 1 cup whole milk (or 2%)
- 1 cup shredded cheddar cheese
- 1 cup cooked breakfast sausage, crumbled or sliced
- 1 cup diced cooked potatoes or hash browns
- ½ cup chopped bell peppers (any color)
- ½ cup chopped onions
- ½ teaspoon salt
- ¼ teaspoon black pepper
- Optional: ¼ teaspoon paprika or hot sauce for added flavor
Instructions
- Preheat your oven to 375°F (190°C). Grease your 8-inch square baking dish with butter or non-stick spray to prevent sticking.
- In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, and optional seasonings until well combined.
- Add the shredded cheese, cooked sausage, diced potatoes, chopped bell peppers, and onions to the egg mixture. Stir gently to evenly distribute all ingredients.
- Pour the mixture into the prepared baking dish, spreading it out evenly with a spatula.
- Place the dish in the preheated oven and bake for 35-40 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
- Remove from the oven and let it rest for 5 minutes before slicing. Serve warm, garnished with additional cheese or herbs if desired.
Tips
- Substitutions: Feel free to swap the sausage for cooked bacon, ham, or a vegetarian option like sautéed mushrooms and spinach.
- Make ahead: Prepare the casserole the night before, cover, and refrigerate. Bake it straight from the fridge, adding an extra 5-10 minutes to the baking time.
- Prevent sogginess: Drain excess moisture from cooked vegetables or potatoes before adding to avoid a watery casserole.
- Cheese variations: Use Monterey Jack, mozzarella, or a blend of your favorite cheeses for different flavors.
Serving Suggestions
This breakfast casserole pairs well with fresh fruit, a side of toasted bread or English muffins, or a light green salad. For a more substantial meal, add crispy bacon or a dollop of sour cream on top.
Variations
To customize this casserole, try adding sautéed spinach and feta for a Mediterranean twist, or incorporate cooked quinoa for extra protein. You can also layer sliced tomatoes or avocado on top after baking for added freshness.
Storage and Reheating
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual portions for 1-2 minutes or reheat the entire casserole in a 350°F (175°C) oven for about 15 minutes until warmed through. For best results, cover with foil to prevent drying out.
Frequently Asked Questions

What if I don’t have an 8-inch pan?

Is it suitable for gluten-free diets?
All ingredients in this recipe are naturally gluten-free. Just ensure any processed ingredients like sausage or cheese do not contain gluten additives. Always check labels if you are sensitive.
