I love the idea of the simplicity of a frittata. Doesn’t it sounds great? A nice warm breakfast on the weekend before the hustle starts: running around between plans, church, family time, or whatever else we have going on that day.

I like the idea… because in reality, my oldest hates eggs, and even if we give them to her every day, she will refuse to eat them. Trust me, we have tried a million and two times to get her to like them in every way possible. She does find that she likes them in cake and cookies, though. Me too, kid.

I might get that easy, warm weekend breakfast after all, because the flavor of this spinach frittata is so good that she gobbled it right up, and just kept saying “Wow Mom, this is amazing! Gosh, this is tasty!”

That is a total parenting win. One, I’ve taught her to compliment well… but to get your child to try something they don’t like, that is also packed full of healthy veggies, is a serious win. Thankfully, she is pretty willing to try new things and rarely do we have to enforce the one bite rule.

We always want to encourage trying food, so the rule is they have to at least take one bite, and if they don’t like it, then they don’t have to eat it. This has taken a lot of pressure off of everyone, and more than likely, when they try the bite, they love it. Who would have thought? Oh yea, me!

By the way I talk on here, you would think that she is a picky eater. Truth be told, there are only three foods she refuses to eat. Eggs, mushrooms, and yogurt. Although with this berry frozen yogurt, she has changed her opinion. So now with this frittata, I guess it’s only one. Spinach frittata for the win.

Tips for Making Spinach Frittata

  • To get the best flavor, caramelize the onions. This takes a little bit of time, but trust me, it’s worth it.
  • If the frittata puffs up really big, just poke a few holes in it and the steam will release. 
  • To get the eggs a little brown without overcooking them, put it under the broiler for a few minutes.
  • Pick your favorite type of hard shredded cheese. We use goats milk cheddar.
  • Use an oven-safe skillet so you can easily pop this baby in the oven.

  • salt and pepper
  • 1/2 cup shredded cheese I used a white cheddar. You can always add more

Instructions

  • In a large skillet (mine is a 12 inch cast iron), place butter, onions, and a dash of salt on low to medium heat. We are trying to caramelize the onions so this takes quit awhile. This also gives it a much richer flavor. If you don't have a ton of time than just saute until soft.
