Ingredients
- ½ pound breakfast sausage
- 3 teaspoons minced garlic
- 12 large eggs
- 1 cup milk
- 2 cups frozen diced potatoes O'Brien (mixed with onions and peppers -you don't have to thaw or cook the potatoes)
- 1 cup chopped spinach , roughly chopped
- 1 ½ cups shredded pepper jack cheese , divided
- 1 ½ teaspoons salt
- ½ teaspoon black pepper
Instructions
- Prepare: Preheat the oven to 350°F. Grease a 9x13 baking dish with nonstick cooking spray.
- Cook sausage: In a large skillet, brown 1/2 pound sausage over medium heat until fully cooked and no longer pink. Add 3 teaspoons garlic and cook one more minute. Place sausage on a plate that has been lined with paper towels to drain the grease.
- Beat eggs and milk: In a large bowl, beat 12 eggs and 1 cup milk. Stir in the 2 cups frozen potatoes, 1 cup chopped spinach, 1/2 cup of the shredded cheese, and the cooked sausage. Add 1 1/2 teaspoons salt and 1/2 teaspoon pepper.
- Bake: Pour the mixture into a baking dish and top with remaining 1 cup cheese. Bake for 45 minutes or until the eggs are firm and the top is slightly golden brown. Cover with foil if browning before the center is set.
- Serve: Let rest for 10 minutes before cutting. Cut into 15-18 squares and serve warm.
Notes
Make ahead: This casserole can be made in advance. Pour the mixture into the pan and refrigerate for up to 24 hours until ready to bake. You can also bake and then allow to cool to room temp, refrigerate and reheat the casserole at 250°F.
Customize: This recipe is really easy to customize. You can swap sausage for leftover ham or bacon. You can also swap spinach for kale or leave out. It's also easy to sneak in extra veggies like mushrooms.
Storage: Store leftovers in a covered container in the refrigerator up to 4 days.
