Ingredients

  • 1 medium-large sweet potato peeled and cut into 1/2-inch cubes
  • 2 teaspoons olive oil
  • kosher salt and black pepper
  • 8 ounces ground Italian or pork sausage
  • 1/4 cup chopped red onion
  • 8 large eggs
  • 1/3 cup shredded cheddar Swiss, or mozzarella cheese
  • 1/4 cup heavy cream or half and half
  • 1 teaspoon dried thyme
  • 2 cups fresh baby spinach
  • 2 garlic cloves minced
  • fresh thyme or parsley optional garnish

Instructions

  • Preheat the oven to 425°F. Line a large rimmed baking sheet with parchment paper.
  • Spread the diced sweet potatoes out on the baking sheet. Drizzle with olive oil and sprinkle with 1/2 teaspoon kosher salt. Toss well, then roast for about 25 minutes, shaking the pan halfway through to give them a turn.

  • While the sweet potatoes roast, set a 10-inch cast-iron or other oven-safe skillet over medium-high heat. When hot, add the sausage and onion. Cook for 5-6 minutes, breaking up the sausage as it cooks.

  • While browning the sausage, crack eggs into a large bowl and whisk well. Add the cheese, cream or half and half, thyme, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Whisk again to combine, then set aside.

  • When the sausage is fully cooked, stir baby spinach and garlic into the skillet. Cook for about 1 minute, until the garlic is fragrant and the spinach is wilted. Remove from the heat and set aside.

  • When the sweet potatoes are finished roasting, stir them into the skillet along with the sausage. Reduce the oven temperature to 350°F.
  • Pour the egg mixture over the sausage and veggies. Gently swirl the pan to distribute evenly.
  • Place skillet in the oven and bake for 18-20 minutes, until the eggs are set and pull away very slightly from the edges of the pan. The frittata may puff up in places; this is normal and will subside as it cools.
  • After removing the frittata from the oven, garnish with fresh thyme, parsley, or extra black pepper as desired. Slice into pieces, serve, and enjoy!

Notes

  • Cream: You can substitute the cream with half and half, whole milk, Greek yogurt, or sour cream, but don’t skip this entirely - some type of dairy is key to help the eggs set up with a fluffy and rich texture.
  • Yield: This makes 4 pretty large servings, or 6 smaller ones, obviously just depending on how you slice it, what else you’re serving with it, etc. The nutrition estimate is based on dividing this frittata made in a 10″ skillet into 6 equal parts.
