1 lb. Hempler’s Ground Breakfast Sausage
1 small yellow onion, diced small
1 red bell pepper, diced small
12 large eggs
1 cup milk
1 tablespoon Dijon mustard
1 teaspoon salt
½ teaspoon pepper
1 (30-oz) package hash brown potatoes (diced or shredded)
2 cups shredded cheddar cheese divided
Heat the oven to 350°F. Grease a 9x13 baking dish with nonstick cooking spray.
In a large skillet, brown the sausage over medium heat, breaking it up into small pieces with a wooden spoon, cooking over medium heat until it is fully cooked and no longer pink, 6-8 minutes. Transfer sausage with a slotted spoon to the 9x13 pan.
Drain the pan and sauté veggies for about 5 minutes, occasionally stirring, until softened. Transfer the vegetable mixture into the 9x13 pan with the sausage.
Add the thawed diced potatoes and 1 ½ cups cheese to the 9x13 pan with the sausage and veggies. Toss gently until evenly combined.
In a separate bowl, beat the eggs, milk, dijon mustard, salt & pepper. Add the egg mixture to the potato mixture and gently combine. Smooth out the top of the casserole and sprinkle with the remaining cheese.
Cover with aluminum foil and bake for 40 minutes. Remove the aluminum foil and bake for 10-15 minutes until the top is golden and the eggs are firm.
Let rest 10 minutes before cutting into squares and enjoying warm.
