Ingredients & Why They Matter

1 lb bulk pork sausage: The star of the dish. Provides rich, savory flavor and protein.
1 cup Monterey Jack cheese: Melts smoothly and adds creaminess.
1 cup sharp cheddar cheese: Offers a bold, tangy flavor and beautiful color.
1/2 cup chopped onion: Brings depth and sweetness when sautéed.
1/2 cup green bell pepper (optional): Adds mild crunch and color; optional for those who love veggies.
4 large eggs: The base of the custard that holds everything together.
2 cups half-and-half: Gives the egg mixture a creamy texture without being too heavy.
1 cup all-purpose flour: Helps set the casserole and gives it a light structure.
1/2 tsp baking powder: Adds a slight lift for fluffiness.
Salt and black pepper to taste: Essential for seasoning and flavor balance.
Green onions or chives (optional): For a fresh, herby garnish that looks as good as it tastes.

Step-by-Step Instructions

Preheat your oven to 350°F (175°C). Lightly grease a 9-inch pie dish or similar baking dish.
Cook the sausage: In a large skillet over medium heat, cook the pork sausage until fully browned and crumbly. Drain excess fat and set aside.
Sauté the vegetables: Using the same skillet, sauté the chopped onion and green bell pepper (if using) until softened, about 5 minutes. Let cool slightly.
Layer the base: Spread the sausage evenly in the prepared dish. Top with the sautéed veggies, then sprinkle both cheeses on top.
Prepare the custard: In a bowl, whisk together eggs, half-and-half, flour, baking powder, salt, and pepper until smooth.
Pour and bake: Pour the egg mixture evenly over the sausage and cheese layers. Bake uncovered for 45–50 minutes, or until the center is set and the top is golden brown.
Cool and garnish: Let the bake rest for 5–10 minutes. Garnish with sliced green onions or chives before serving.

Pro Tips for the Perfect Breakfast Bake

Drain sausage well: Excess grease can make the dish soggy.
Customize the veggies: Add mushrooms, spinach, or diced tomatoes if you like more variety.
Make it ahead: Assemble the night before, refrigerate, and bake in the morning.
Test for doneness: Insert a knife in the center—if it comes out clean, it’s done!
