Easy Cowboy Breakfast Casserole with Sausage and Peppers Tips, FAQ & printable recipe

Tips for success

For a more vibrant flavor, add finely chopped fresh herbs like chives or parsley to the egg mixture before pouring it over the base. These herbs add a fresh note that cuts through the richness of the sausage and cheese.

If you enjoy a bit more heat, a dash of hot sauce stirred into the eggs can elevate the overall profile of the dish without overpowering the other ingredients.

If you find the top of the casserole is browning too quickly before the center is fully cooked, cover the dish loosely with a piece of aluminum foil. This allows the potatoes and eggs to finish cooking without burning the cheese. Always ensure the foil is removed during the final few minutes of baking to allow the cheese to achieve a perfect, golden finish.

Variations

• Vegetarian Option: Replace the breakfast sausage with extra diced bell peppers, mushrooms, and zucchini. Sauté the vegetables briefly in a pan before adding them to the dish to ensure they are tender and have lost excess moisture before baking.
• Spicy Kick: Incorporate diced jalapeños and a teaspoon of crushed red pepper flakes into the egg mixture. Use a spicy sausage blend and extra pepper jack cheese to intensify the heat and create a bolder breakfast profile.

Storage and make-ahead

Fridge

Store in an airtight container in the refrigerator for up to 3 days. Allow the casserole to cool for no more than 2 hours before refrigerating.

Freezer

Wrap individual portions tightly in plastic wrap and store in a freezer-safe bag for up to 1 month. Thaw overnight in the refrigerator before reheating.

Reheat

Reheat portions in the microwave on medium power until heated through, or place in a 350°F oven until warmed to an internal temperature of 160°F (71°C).

Store any leftovers in an airtight container or wrap the baking dish tightly with plastic wrap. Keeping the casserole properly sealed prevents it from absorbing other odors in the refrigerator and helps maintain its moisture.

Properly stored, the leftovers will remain safe and flavorful for several days, making them an excellent option for quick, pre-portioned breakfasts throughout the busy work week.

This dish can be prepared in advance by assembling the base and the egg mixture the night before. Keep the assembled dish, covered, in the refrigerator until you are ready to bake it the next morning. If baking directly from the refrigerator, you may need to add five to ten minutes to the total baking time to ensure the center reaches the required temperature of 160°F (71°C).

Serving ideas

Serve the casserole warm, directly from the baking dish. It pairs exceptionally well with a side of fresh fruit or a simple green salad to balance the richness of the sausage and cheese.

Because it is a complete meal, it requires very little accompaniment, making it an ideal centerpiece for a relaxed weekend brunch or a quick family breakfast where efficiency and comfort are the top priorities.

When slicing, use a sharp knife to cut through the crust and the firm egg base to ensure clean squares. If serving to a group, place the dish on a heat-proof mat in the center of the table and allow guests to serve themselves.

The casserole holds its heat well, so it will remain warm and satisfying even as the meal progresses, ensuring everyone enjoys a comforting, hearty breakfast.

Ingredients

• 4 cups diced potatoes
• 1 cup diced red and green peppers
• 1 lb cooked crumbled breakfast sausage
• 8 large beaten eggs
• 2 cups shredded pepper jack cheese

Instructions

1. In a large 9x13 inch ceramic baking dish, spread the diced potatoes evenly across the bottom. Scatter the diced red and green peppers over the potatoes, then top with the cooked crumbled breakfast sausage, ensuring a balanced distribution of ingredients throughout the dish.
2. Pour the beaten eggs evenly over the potato and sausage mixture until the ingredients are just covered. Sprinkle the shredded pepper jack cheese generously over the top of the egg mixture to create an even, cheesy layer.
3. Place the baking dish into a preheated 375°F oven and bake until the edges are golden brown and bubbling. To cook the eggs through to a safe internal temperature of 160°F (71°C), continue baking until the center is firm. Let the casserole rest for five minutes after removing it from the oven to allow the layers to settle, making it easier to slice neatly.
