Spinach Mushroom Frittata

Quick Answer

To make Spinach Mushroom Frittata, cook the fillings first, whisk together eggs and dairy, then bake until the center just sets and the edges puff lightly. It works because the fillings are cooked before the eggs ever have to carry them.

Jump to Recipe

This spinach mushroom frittata cooks the vegetables first, then bakes them right into the eggs until the center sets and the edges turn golden. It's a good way to use up whatever's left in the fridge.

It's a good weekend brunch dish or a light dinner with a salad. Cook your vegetables until any extra moisture cooks off before adding the eggs.

Ingredients

  • 8 large eggs
  • 1/2 cup cream or milk
  • 1 cup spinach
  • 1 cup mushrooms
  • 3/4 cup parmesan
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1 tablespoon olive oil or butter

Instructions

  1. 1Heat the oven to 375°F.
  2. 2Cook the spinach and mushrooms in a little oil until the moisture cooks off and the flavor wakes up.
  3. 3Whisk the eggs, cream, salt, and pepper until fully combined.
  4. 4Scatter the fillings into a skillet or crust, pour over the eggs, and top with the cheese or herbs.
  5. 5Bake until the center is just set and the edges look puffed, 20 to 35 minutes depending on the pan.
  6. 6Rest before slicing so the eggs firm up cleanly.

Pro Tips

  • Cook the vegetables first or they leak water into the eggs.
  • Pull the pan when the center still has a slight wobble because carryover heat finishes the job.
  • A little sharp cheese goes farther than a mountain of bland cheese.

Substitutions

Swap in roasted peppers, bacon, or broccoli if you want a different direction.
Half-and-half and milk both work; cream just tastes richer.
A gluten-free crust works fine if you are making the quiche version.
