Steak Frittata

When all else fails, clean your house and make a frittata. It really is game changer when you are needing some peace of mind. My new Steak and Caramelized Onion Frittata is so simple and only involves minimal ingredients.

It’s true that anytime I am feeling overwhelmed, I’ll throw a frittata in the oven and clean my house. Wouldn’t you agree that there is something so magical about having both a clean house and something in the oven cooking? Having a clean space and meal prepped for the week is sure to make anyone do a little dance.

Steak and Caramelized Onion Frittata

One of my favorite ways to make a frittata is using leftovers or ingredients that are about to go bad. Instead of throwing things out, I love tossing everything in a bowl with some eggs and creating something delicious. Sometimes just a recipe that is thrown together using random ingredients can turn out to be pretty delicious. If you don’t have everything in your fridge that goes along with this recipe, get creative and make your own version.

What leftovers can you use for a Frittata?

  • Chicken & Fajita Peppers
  • Steak & Asparagus
  • Pot Roast & Sweet Potatoes
  • Sausage & Tomatoes
  • Bacon and Zucchini
  • Chicken and Broccoli
  • There are many more options that you can throw together. This is just a few that I have done in the past that have worked out really well together. My family always loves a good frittata.

Tips for making the perfect Frittata:

  • Use a cast iron skillet coated with olive oil.
  • Incorporate coconut milk or Mac’s Sauce to your egg mixture to give it a creamy texture.
  • Use any protein leftovers along with some veggies to make different versions. These can be so versatile and save you from throwing out and wasting leftovers.
  • Make sure to over-bake. Bake on 350F for 25-30 minutes for the perfect texture.
