Equipment

  • 10-inch oven-safe skillet
  • Mixing Bowl
  • Whisk

Ingredients
  

  • 2 tbsp olive oil
  • 1 1/2 cups cremini mushrooms sliced (about 4 oz)
  • 1 cup red bell pepper thin 1-inch strips (about 4 oz)
  • 1 clove garlic minced
  • 3 cups baby spinach loosely packed (about 3 oz)
  • 8 large eggs
  • 1/4 cup heavy cream
  • 1/2 tsp sea salt
  • 1/4 tsp black pepper
  • 1/2 cup feta cheese crumbled (about 2 1/2 oz)
  • 1 tbsp fresh parsley chopped, for serving

Instructions
 

  • Eggs: Heat the oven to 350°F. Whisk the eggs, heavy cream, sea salt and black pepper until even in color.
  • Vegetables: Heat the olive oil in a 10-inch oven-safe skillet over medium heat. Cook the mushrooms and red bell pepper 7 to 8 minutes, until their liquid has cooked off and the mushrooms are browning.
  • Spinach: Stir in the garlic for 30 seconds, then add the spinach in handfuls and cook 1 to 2 minutes until wilted and the pan is dry.
  • Assemble: Spread the vegetables evenly, pour the eggs over, scatter the feta cheese on top and stir once gently. Move the pan to the oven right away.
  • Bake: Bake 15 to 20 minutes, until puffed and set at the edges with a slight jiggle in the center.
  • Rest: Rest 5 minutes in the pan, sprinkle with the parsley and cut into 6 wedges.

Notes

Cook the vegetables dry: any liquid left in the pan ends up as a watery frittata.
Pull it early: take it out while the center still jiggles slightly. It finishes setting as it rests.
Other cheeses: cheddar, mozzarella or Gruyere can replace the feta; add a pinch more salt.
Nutrition is for 1 of 6 slices.
Storage: up to 4 days in the fridge, or 2 months in the freezer, wrapped by the slice.
