Although a traditional Cuban frittata recipe normally includes potatoes, I’ve opted to swap the potatoes for diced turnip! Potatoes are just too high in carbs and all that starch can cause sugar spikes.

Turnips make an excellent swap for potatoes because their texture and appearance are quite similar and their flavor is pretty mild. 

Growing up in a Latin household, we loved our frittatas for breakfast but we know them as Spanish tortilla or Cuban tortilla. I remember my parents making all sorts of variations of this staple. My dad didn’t cook often, but anything that involved eggs was his specialty.

When dad announced that he was going to make a Cuban tortilla, it always brought cheers from us kids. My Mom is a fantastic cook, so I think the excitement we had was more about seeing him in the kitchen and the banter between my parents.

My parents would make their frittatas on the stovetop and would flip them to cook on both sides. All that meant is most of the time the frittata wasn’t very pretty. However, that never stopped us from digging in.

Now I opt to make my low-carb Cuban tortilla in the oven to avoid having to flip it all. It’s easier and tastes just as delicious, that’s a win-win for me!

One of the best things about a great frittata recipe is how customizable they are. You can pack a lot of vegetables, protein, and fat in one delicious meal.

A frittata or crust-less quiche is an easy dish, that can be made low carb and keto-friendly rather effortlessly. Honestly, the sky’s the limit. The only non-negotiable item is the eggs.

Although I mentioned earlier that I prefer to have this dish in the morning or early afternoon. It does however make for an easy and satisfying dinner. 

You can even make this recipe in a well-greased muffin tin for an easy on-the-go breakfast option. 

To make this low-carb frittata you’ll start by cooking your diced turnips, onions, and peppers in an oven-safe skillet. Once the turnips are nice and tender add in your chorizo, this is where the magic starts to happen. 

The fat of the chorizo will start to cook down and your turnips will soak it all up! Then it’s just a matter of whisking your eggs and adding them to the skillet. You’ll toss the whole thing in the oven and let it bake for about 20 to 25 minutes. It’s really that easy!
