Spinach-Pepper Frittata {Recipe}

spinach frittata recipe

I’ve never been really into eggs, but ever since I had the girls I’ve been making them a lot more often. They are super easy to make, a great source of protein, and an excellent way to add in other nutritious and delicious foods like vegetables and cheese. Although eggs are typically thought of as a breakfast food, when I make eggs it’s usually for dinner. As usual, I try to make my meals using seasonal produce (like the Tomato-Basil Mozzarella Frittata I made over the summer), so a couple of weeks ago (before Sandy visited) I made a frittata using spinach, red peppers, and onions. I had shredded mozzarella cheese left from homemade pizza the week before, and fresh thyme, which has become a staple in my fridge since it goes with so many foods I make for the girls.

Frittata’s are traditionally started in a skillet on the stove and finished in the oven, but I recently found it easier to bake it in the oven after I sauté the vegetables – like a quiche without the crust. The perfect balanced meal with a side salad and a whole grain roll.

  • 1-2 teaspoons olive oil
  • 1 yellow onion thinly sliced into half moons
  • 1 red pepper thinly sliced
  • 5 ounces baby spinach
  • 1 tablespoon grainy Dijon mustard
  • 4 whole eggs
  • 4 egg whites
  • 1/3 cup nonfat milk
  • Fresh thyme
  • Kosher salt & freshly ground pepper to taste
  • Cooking spray
  • 1 cup part-skim shredded mozzarella cheese


  1. Preheat oven to 350 F.
  2. Heat olive oil in a skillet over medium heat. Add onion and saute 3 minutes. Add pepper slices and continue to saute 3-5 minutes more until softened. Add spinach and saute until wilted. Mix in mustard and set aside.
  3. In a medium bowl, whisk together eggs, egg whites, milk, thyme, and salt and pepper to taste.
  4. Spray an 8-9" round baking dish with cooking spray. Spread 1/3 of the cheese on the bottom of the baking dish. Top with the sauteed vegetables. Pour egg mixture on top and sprinkle with 1/3 of the cheese. Bake for 20 minutes.
  5. Remove frittata and sprinkle with remaining 1/3 of the cheese. Bake another 10 minutes until frittata is fully cooked and cheese is beginning to bubble and brown.
