Ingredients

  • 12 large eggs
  • 1/2 cup heavy cream
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon freshly ground black pepper
  • 1/2 cup shredded Gruyere cheese
  • 1/2 cup shredded fontina cheese
  • 2 1/2 oz about 1/2 cup feta cheese crumbled
  • 1/4 cup grated Parmesan cheese
  • 2 tablespoons olive oil
  • 2 cups cherry or grape tomatoes halved (about 10 oz)
  • 1 cup fresh basil thinly sliced
  • 1 teaspoon red pepper flakes
  • 1 teaspoon dried Italian seasoning
  • 1/3 cup scallions minced
  • 2 tablespoons shallots minced
  • 1 1/2 teaspoons garlic minced
  • 4 cups fresh baby spinach

Instructions

  • Preheat the oven to 350°F (175°C).
  • In a large mixing bowl, whisk together the eggs, heavy cream, salt, and black pepper until fully combined. Gently fold in the Gruyere, fontina, feta, and Parmesan cheeses. Set aside.
  • Heat the olive oil in a 10-inch oven-safe skillet over medium heat. Add the halved tomatoes, basil, red pepper flakes, and Italian seasoning. Cook for 4 to 5 minutes, stirring occasionally, until the tomatoes soften and release their juices.
  • Add the scallions and shallots to the skillet and cook for 2 minutes, until fragrant and softened. Stir in the garlic and cook for an additional 1 minute.
  • Add the spinach and sauté for 1 to 2 minutes, until just wilted. Season lightly with additional salt and pepper if desired. Reduce heat to medium-low.
  • Pour the egg and cheese mixture into the skillet. Gently stir once or twice to evenly distribute the vegetables. Cook for 3 to 5 minutes, until the edges begin to set.
  • Transfer the skillet to the preheated oven and bake for 15 to 20 minutes, or until the center of the frittata is set.
  • Remove from the oven and allow the frittata to rest in the skillet for 5 minutes. Loosen the edges with a spatula, unmold if desired, and serve warm.
