Easy Fajita Frittata Recipe 🥘

Sharing is caring!

Wondering what to do with leftover fajita meat? Make my Fajita Frittata Recipe. (Isn't it fun to say fajita frittata? Well, at least I think so. I woke up this morning with fajita frittata on the brain. Then I said fajita frittata at least twenty times in a row, laughing the whole time. For some reason, it tickles me.)

You can easily make this fajita frittata recipe from scratch. All you need to do is sauté some sliced peppers and onions, then chop up some leftover steak or chicken. Mix this up well, and you're ready to roll. We typically have chorizo around the house, which we heat, crumble, and toss on top of the frittata for a little extra zing. Let's see what it takes to create delicious Mexican-inspired fajita frittata flavors!

5 Reasons to Love This Recipe

I have a soft spot for Mexican cuisine, and this delicious egg fajita recipe is among my top favorites for all the right reasons:

  1. A quick and easy delicious breakfast recipe.
  2. Simple ingredients and straightforward instructions.
  3. Easy to customize with any Mexican-style ingredients.
  4. Low-carb, protein-packed breakfast.
  5. One of the most creative and tastiest recipes with leftover fajita meat.

Is Fajita Frittata Low-Carb?

Yes, fajita frittata is made with simple low-carb ingredients like eggs,bell peppers, and onions; spices like cumin and chili powder; and (optionally) meat like chicken. All of which is low-carb-friendly.

This leftover fajita recipe is low-carb at 3 g net carbs per serving. Remember that peppers and onions (the traditional mix for fajitas) have a higher carb count. I typically add more peppers than onions to lower the frittata's net carb count.

Fajita Frittata Recipe Ingredient List

For this delicious egg fajita recipe, you need just a handful of simple ingredients:

  • 3 large eggs
  • ½ cup fajita leftovers
  • 2 tablespoons cooked chorizo (optional)
  • 2 tablespoons organic heavy whipping cream
  • ½ tablespoon grass-fed butter
  • 1 pinch kosher salt
  • 3-4 cranks of fresh cracked black pepper

Ingredients Substitutions

Some excellent swaps to the ingredients listed above are:

  • Fajita leftovers: Sauté some bell peppers and onions, tossing in whatever proteins you might have on hand. My favorites are chicken or steak frittata. Ensure all the additions are well-cooked, as the frittata does not get hot enough to cook the ingredients.
  • Butter: Use ghee or clarified butter.
  • Chorizo: Use cooked breakfast sausage, homemade bacon bits, or cooked Italian sausage.

Additional Ingredients

I often jazz up the fajita eggs recipe with these optional ingredients:

  • Veggies: The recipe loves diced tomatoes, spinach, or sautéed mushrooms.
  • Cheese: Add some shredded cheddar, Monterey Jack, jalapeño Havarti, or some queso fresco.
  • Spices: This Mexican-style meal pairs well with chili powder, red pepper flakes, chipotle powder, and more.
  • Sauces: Did somebody say HOT SAUCE? Pull out your favorite sugar-free hot sauce and load it on the frittata. This is one of my favorite additions to this recipe.
  • Sour cream: If you put hot sauce on the frittata, add a dollop of sour cream to round out the heat.
  • Avocado: Like sour cream, avocado adds a cooling effect to the spiciness. PLUS, it adds a ton of healthy fats… a keto lover's delight!
  • Salsa: Whether you're buying pico de gallo, salsa verde, or any store-bought masterpiece, always check the ingredients for hidden sugars.

Note: These ingredients are optional and not part of the recipe. Use them only to punch up the frittata's flavors.

How to Cook Fajita Frittata: Complete Cooking Guide

Cooking Method

  • Baking

Preparation Steps

  1. Gather the tools and ingredients.
  2. Preheat oven to 375°F (190°C).

Cooking Instructions

  1. Reheat fajita leftovers in a non-stick skillet. When hot, set aside.
  2. In a bowl, crack 3 eggs and beat well.
  3. Add whipping cream, salt, pepper, and heated fajita leftovers. Mix to incorporate.
  4. Heat your cast iron breakfast skillet over medium heat. Melt butter.
  5. Coat the pan with the melted butter.
  6. Add the egg mixture and place in the oven.
  7. Cook for 12 minutes or until lightly set.
  8. Change the oven from bake to broil. Add chorizo to the top of fajita (optional).
  9. Broil for 2-3 minutes or until golden brown.
  10. Remove from oven, serve hot and enjoy!

💡 My Pro Tip

To prevent the egg from sticking to the cast iron, use a little more butter than you would if you were cooking plain eggs. If using a mini pan like the one in this recipe, melt ½ tablespoon of grass-fed butter first. Next, take the pan off the heat and coat the entire bottom and sides with the butter. There will be extra butter at the bottom of the pan. When you add the egg mixture, the melted butter will sear the eggs nicely, so your fajita frittata will slide right out of the pan!

Remember, the center of the frittata needs to be set (meaning it doesn't jiggle when you shake the pan). The last thing you want to do is cut into a soupy frittata… if you are unsure, just use a fork and gently poke through the top, pulling a little to one side. You will quickly see if the eggs are cooked or not.

⏲️ Time-Saving Tips

  • Use leftover fajitas! Cooking from scratch takes a lot more time.

What to Serve with Fajita Frittata?

Some great sides and condiments that complement fajita frittata's flavors and texture include:

  • Guacamole: For a full Mexican experience, pair the frittata with a side of guacamole. It will add rich flavors and a creamy texture to the frittata.
  • Cucumber Feta Salad: The cucumber salad adds freshness and rich contrast to the fajita frittata. The cheese in the salad rounds out the frittata's spiciness well.
  • Sweet Fennel Sausage: Pair the savory sausage with the fajita frittata for a delightful breakfast or brunch meal.
  • Lardon: The crispy, savory bacon tastes fantastic with the fajita frittata for breakfast.
  • Grilled Asparagus: The asparagus adds a good crunch and flavor contrast to the frittata.

Storage and Reheating Instructions

Storage

  • Stores for 2-3 days in an airtight container in the fridge. After that, the egg consistency is a bit off.

Reheating

  • Reheat in a pan in the oven at 350°F (180°C) until heated through. This is my preferred method. You could also slice the frittata and add it to a nonstick pan over medium heat with some melted butter in the pan. It will heat faster with a cover on the pan. The third method would be in the microwave, but the chicken will get tough, and the eggs will take on a strange texture.

Recipe Conclusion

Sometimes, you have to be creative with what you have on hand to make a delicious breakfast. Whether you have made steak fajitas at home or enjoyed some out at a restaurant, save a little bit for this tasty Fajita Frittata Recipe the next morning. I thoroughly enjoyed this breakfast recipe (with a bit of chipotle sauce to crank up the heat!) this morning. It was a win all around!

The fajita frittata recipe doesn't fall into the paleo world because of the cream used. It could be made without the cream, but I like the consistency that cream adds to the frittata. For 2 tablespoons of cream, I'm okay bending the rules just a bit. If you're not paleo, add a handful of cheddar cheese right before the broiler is turned on for a delicious cheesy fajita frittata! I hope you enjoy the Mexican flavors in this recipe as much as we do. Drop your questions and other leftover fajita ideas in the comments.

FAQs

You will know your frittata is done if the eggs are fully set and no longer runny. A golden brown edge and firm texture are also good indicators of doneness. Alternatively, use an instant-read thermometer to check for doneness. Eggs are fully cooked and safe to eat at 160°F (71°C).

The longevity of a frittata depends on the type of ingredients used and the storage method. It can remain fresh in the fridge for 3-4 days.

The frittata's internal temperature should reach 160°F (71°C) to ensure that the eggs are fully cooked and safe to eat.
