Ingredients:
- 30 oz Frozen Shredded Hash Browns
- 1 lb Breakfast Sausage (casings removed)
- 1 medium Yellow Onion, finely diced
- 1 medium Bell Pepper (Red or Green), finely diced
- 2 cloves Garlic, minced
- 12 Large Eggs
- 2 cups Whole Milk (or Half & Half)
- 1/4 cup All-Purpose Flour
- 1 teaspoon Dry Mustard Powder
- 1 teaspoon Salt (adjust based on sausage)
- 1/2 teaspoon Freshly Ground Black Pepper
- 2 cups Sharp Cheddar Cheese, shredded (divided)
- 2 tablespoons Fresh Chives or Parsley, chopped (for garnish)
Instructions:
- Grease the 9x13 inch baking dish generously. Preheat oven to 375°F (190°C).
- Brown the sausage in an oven-safe skillet over medium heat, breaking it up with a spoon. Drain off most of the fat, leaving about 1 tablespoon. Add onion, pepper, and garlic; sauté until softened (about 5 minutes). Set aside to cool slightly.
- Spread the slightly thawed hash browns evenly across the bottom of the prepared baking dish. Sprinkle half of the shredded cheddar over the top of the potatoes.
- Scatter the cooked sausage and vegetable mixture evenly over the cheese and potatoes. Sprinkle the remaining half of the cheddar on top.
- In a large mixing bowl, whisk together the eggs, milk, flour, mustard powder, salt, and pepper until completely smooth and homogenous.
- Slowly and evenly pour the egg custard mixture over the layered ingredients in the baking dish. Gently press down with a spatula to ensure the liquid seeps down to the potatoes. For best results, cover and refrigerate for at least 2 hours, or overnight.
- Remove the casserole from the fridge 30 minutes before baking (if refrigerated). Bake uncovered for 50–60 minutes.
- The casserole is done when the centre is set (no jiggle when gently shaken) and an internal temperature reads 165°F (74°C). The top should be nicely golden brown.
- Let the casserole rest for 10 minutes before slicing and garnishing with fresh chopped chives or parsley.
