Slow Cooker Christmas Morning Breakfast Casserole (Print version)

A cozy overnight slow cooker breakfast casserole with sausage, hash browns, eggs, peppers, and cheddar for a low-stress Christmas morning.

# Ingredients:

For the casserole

01 - 1 lb (450 g) breakfast sausage, preferably gluten-free if needed
02 - 1 tablespoon unsalted butter or cooking spray, for greasing
03 - 1 bag (30 oz / 850 g) frozen shredded hash browns
04 - 1 red bell pepper, diced
05 - 1 green bell pepper, diced
06 - 1/2 cup (75 g) finely diced yellow onion
07 - 2 1/2 cups (280 g) shredded sharp cheddar cheese

For the egg mixture

08 - 12 large eggs
09 - 1 cup (240 ml) whole milk
10 - 1/2 cup (120 g) sour cream
11 - 1 teaspoon dry mustard
12 - 1 teaspoon garlic powder
13 - 1 teaspoon kosher salt
14 - 1/2 teaspoon black pepper
15 - 2 tablespoons sliced green onions, for serving

# Instructions:

01 - Cook the sausage in a large skillet over medium-high heat for 6-8 minutes, breaking it into small crumbles, until no pink remains. Drain off excess grease and let it cool slightly.
02 - In a large bowl, whisk the eggs, milk, sour cream, dry mustard, garlic powder, salt, and black pepper until mostly smooth.
03 - Coat a 6-quart slow cooker insert with butter or cooking spray, covering the bottom and sides well.
04 - Add half the frozen hash browns, half the sausage, half the bell peppers, half the onion, and half the cheddar. Repeat the layers with the remaining hash browns, sausage, vegetables, and cheese.
05 - Pour the egg mixture evenly over the layered ingredients. Press lightly with a spoon so the custard sinks through the potatoes.
06 - Cover and cook on low for 7-8 hours, or on high for 3-4 hours, until the center is set and an instant-read thermometer registers 160°F.
07 - Turn off the slow cooker and let the casserole rest for 10 minutes. Sprinkle with green onions, then scoop or slice into portions.

# Good to know:

01 - Use a 6-quart slow cooker for the best depth and even cooking.
02 - If assembling the night before, refrigerate the filled insert until ready to cook.
03 - Check early if your slow cooker tends to run hot.
