Preheat and Prep

Start by heating your oven to 180ºC (355ºF). While the oven’s getting hot, grab a non-stick skillet and warm it up over medium-high heat.

Cook the Sausage

Add the pork sausage to the pan. Break it apart with a spoon or spatula as it cooks. You’re aiming for a nice, even browning all over.

Add Veggies and Season

Once the sausage is browned, toss in the diced onion, both red and green bell peppers, and garlic. Sprinkle in some salt and pepper for seasoning. Cook everything together for another 7-10 minutes.

Combine Ingredients

In a large mixing bowl, combine the browned sausage mixture with shredded Gruyere cheese, half of the cheddar cheese, and the eggs. Stir until everything is well mixed.

Bake

Grease a casserole dish and pour your egg mixture in. Spread it evenly, then sprinkle the rest of the cheddar cheese on top. Slide it into the oven and bake for 20 minutes. You’re looking for a bubbly, golden top and a set middle.

Serve and Enjoy

Let the casserole cool for a couple of minutes, then garnish with chopped chives and fresh parsley. Now, it’s ready to serve!

Recipe Notes and Expert Tips

Making a breakfast casserole is pretty straightforward, but here are a few tips and tricks to ensure yours turns out perfectly every time:

• Cheese: While this recipe uses Gruyere and cheddar, feel free to experiment with other cheeses. Pepper Jack cheese can add a nice kick, and Swiss cheese gives a lovely melt.
• Make-Ahead: You can assemble this casserole the night before and pop it in the oven in the morning. Just cover it and keep it in the fridge overnight.
• Can I use egg whites instead of whole eggs? Sure can! If you’re looking to lower the fat content, using egg whites is a great option. Just remember, you may need to adjust the quantity since egg whites are less voluminous than whole eggs.
• Leftover Veggies: This recipe is great for using up leftover veggies. Just about anything works—spinach, zucchini, bell peppers, you name it.
• Customizing Protein: Not a fan of pork sausage? Swap it out for breakfast sausage, bacon, ham, or even a vegetarian alternative for a different flavor profile.
• Egg Ratio: If you prefer a firmer casserole, you can add an extra egg or two. This will help bind the ingredients together more solidly.
• Vegetarian option: Swap the pork sausage for a vegetarian alternative or extra veggies. Mushrooms, spinach, and zucchini are great for adding bulk and flavor.
• Is this casserole keto-friendly? Yes! Just check the carb content of your sausage to make sure it’s keto-friendly too.

How to Store Leftover Breakfast Casserole

Sausage and egg casserole stores beautifully, making it a great option for meal prep or for enjoying a quick and delicious breakfast throughout the week.

• Cool Down: Allow the casserole to cool completely before you store it.
• Refrigerate: Transfer the cooled casserole to an airtight container and refrigerate. Properly stored, it will keep for 3 to 4 days.
• Freeze: If you want to extend its shelf life even further, you can freeze the casserole. Cut it into individual servings, wrap each piece tightly in plastic wrap, and then foil. Stored this way, it can last for up to 3 months. Just thaw overnight in the fridge before reheating.
• Reheating: To reheat, you can either use the oven or the microwave. If using the oven, cover the casserole with foil to prevent it from drying out and bake at 350°F until heated through. For the microwave, a couple of minutes on high should do the trick, but you might want to cover it with a microwave-safe lid or paper towel to keep the moisture in.

What to Serve with Breakfast Casserole

Here are a few ideas to complement the flavors and make your meal even more satisfying.

Fresh Fruit Salad

A colorful fruit salad is the perfect contrast to the rich and savory flavors of the casserole. Mix together seasonal fruits like berries, oranges, and melons. The freshness and slight acidity of the fruit will balance the meal and add a burst of color to your table.

Toast or Artisan Bread

Serving your casserole with a side of crusty bread or artisan toast can soak up all the lovely flavors. Plus, it adds a nice textural contrast to the soft and fluffy casserole. For a little extra indulgence, try a garlic or herbed butter on the bread.

Roasted Potatoes

For those who love a hearty breakfast, roasted potatoes make an excellent addition. Toss them with olive oil, garlic, rosemary, and a touch of paprika, then roast until crispy. This side dish adds a delicious crunch and satisfies even the biggest appetites.
