  • 1 7-ounce package sausage links
  • 1 medium yellow onion, chopped
  • 3 garlic cloves, pressed or minced
  • 1 red bell pepper, seeded and chopped
  • 1 green bell pepper, seeded and chopped
  • 2 + 1/2 cups shredded cheddar cheese (hand shredded from a block of cheese*)
  • 1 32-ounce bag of frozen tater tots
  • 2 cups milk
  • 8 eggs
  • 1 teaspoon sea salt
  • 1/2 teaspoon black pepper, freshly ground
  • 8 slices of thick-cut bacon, cooked until crispy and crumbled
  • 2 green onions, thinly sliced

*WHY GRATE YOUR OWN CHEESE FOR THIS RECIPE? Pre-shredded cheese is covered in a coating to keep it from clumping together. Because it doesn’t melt as smoothly as hand-grated cheese, breakfast casseroles can end up oily on the top and sides.  


RECIPE PREP: Adjust oven rack to the middle position. Preheat oven to 350°F. Grease the bottom and sides of a 9 x 13 casserole dish or two 8 x 8 square bakers.

  1. Slide the sausage links out of their casings and into a large skillet. With a wooden spatula, roughly chopping the links into pieces while cooking. They’re done when the meat is no longer pink. Lift the cooked pieces out of the pan with a slotted spoon. Transfer them to an extra-large mixing bowl. Reserve the drippings for sautéing the veggies.
  2. Add onion, garlic and bell pepper to the pan. Cook until tender. Transfer veggies to the mixing bowl. Add shredded cheese and mix with a spatula until combined. Fold in the frozen tater tots.
  3. In a separate mixing bowl, whisk together the milk, eggs, salt and pepper. Pour the wet mixture over the tater tots, cheese and veggies. Fold everything together until well incorporated. With a spatula, transfer the breakfast casserole mixture into your greased baker(s).
  4. Bake for approximately 55-65 minutes, or until the egg mixture is completely set and the top is golden. Remove from the oven and allow it cool for 5 minutes.
  5. Sprinkle crispy bacon pieces and sliced green onions over the top of your tater tot casserole. Serve while toasty warm. Enjoy!
