Ingredients

• 1 pound ground sausage
• 1 medium yellow onion, chopped
• 1 small green bell pepper, chopped
• 2 cloves garlic, minced
• 1 teaspoon dried thyme
• 1 teaspoon dried marjoram
• ½ teaspoon crushed rosemary
• ¼ teaspoon red pepper flakes
• 10 large eggs
• 1 cup milk (whole or 2%)
• ½ teaspoon salt
• ½ teaspoon freshly ground black pepper
• 1 cup shredded cheddar cheese
• 1 cup shredded pepper jack cheese

Instructions

Step 1: Prepare the Oven and Baking Dish

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or butter.

Step 2: Cook the Sausage and Vegetables

In a large skillet over medium heat, cook the ground sausage. Once the sausage is about halfway browned, add the chopped onion and cook for 2 minutes. Stir in the chopped green bell pepper and continue cooking until the vegetables are softened.

Step 3: Add Seasonings

Reduce the heat to low. Add the minced garlic, dried thyme, marjoram, crushed rosemary, and red pepper flakes. Stir well and cook for 1 minute until fragrant. Transfer the sausage mixture evenly into the prepared baking dish.

Step 4: Prepare the Egg Mixture

In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, and ½ cup each of the cheddar and pepper jack cheeses until well combined.

Step 5: Assemble the Casserole

Pour the egg mixture evenly over the sausage and vegetable mixture in the baking dish. Sprinkle the remaining cheddar and pepper jack cheeses over the top.

Step 6: Bake

Bake for 35–40 minutes, or until the center is fully set and the top is lightly golden brown. A knife inserted into the center should come out clean.

Step 7: Serve

Allow the casserole to rest for 5–10 minutes before slicing. Serve warm and enjoy.
