Equipment

Ingredients

  • 1 pound sweet potato peeled and diced into ½-inch cubes
  • 1 tablespoon olive oil
  • ¼ teaspoon garlic powder
  • ¼ teaspoon paprika
  • ¼ teaspoon cumin
  • kosher salt and freshly ground black pepper
  • 8 ounces bacon
  • 1 pound breakfast sausage mild, medium or spicy, your choice
  • ½ large onion diced
  • 1 green bell pepper deseeded and diced
  • 2 cloves garlic minced
  • 12 large eggs
  • cup milk (dairy or dairy-free)
  • optional: shredded cheese and sliced green onion for garnish

Instructions

  • Preheat your oven to 400°F (200°C) and get a 9x13-inch casserole pan out. On one baking sheet pan, toss the diced sweet potato with olive oil, garlic powder, paprika, cumin, salt, and pepper. Set aside.

  • On another sheet pan, add slices of bacon. Then place both the sweet potato and bacon in the oven and cook for 15 to 20 minutes, or until the bacon is crispy. The bacon will be done first, so keep an eye on it and remove it from the oven when it's done, then place it on a paper towel-lined plate. Stir the sweet potato and continue cooking it for another 15 minutes.

  • While the sweet potato is cooking, cook the breakfast sausage in a pan on medium-high heat. Once it's browned, remove it with a slotted spoon and place it in the casserole pan.

  • Drain off all but a tablespoon of grease from the pan, then saute the onion and bell pepper for 4 to 5 minutes. Add the minced garlic and saute for another minute. Transfer this mixture to the casserole pan.

Notes

  • One pound of sweet potatoes is usually one medium to large sized sweet potato. If it's slightly over, that's fine as well.
