Ingredients

individual ingredients for 6 ingredient beef fajitas without marinade laid out against a white background.
  • Fajita Meat: I use organic pasture raised fajita meat, I love that it is precut which makes it incredibly easy.
  • Taco Seasoning: I use my Organic Homemade Taco Seasoning, but store bought also works. I do this in place of marinating for a quick and easy way to get lots of flavor.
  • Bell Peppers: You can use any color bell peppers for this.
  • Onion: I use organic yellow onion, but white also works.
  • Avocado Oil: I love using this oil for flavor! But, EVOO also works too.

Tips

  • You can use skirt steak or flank steak if you can't find precut fajita meat. Slicing it into thin strips before cooking will let it cook quickly, keeping it tender and juicy.
  • Use any color bell peppers you have on hand.
  • Yellow or white onion is fine, either works and you'll get a similar flavor.
  • Serve over Easy Bone Broth Rice with a squeeze of lime for more protein if you prefer!

Beef Fajitas Without Marinade FAQ's

What's the difference between fajitas and tacos?

Fajita meat is grilled or sautéed with bell peppers and onions, where taco meat is not. Fajitas usually have more simple or plain toppings, as opposed to tacos which can have many options. But, you can also add taco toppings like avocado, salsa, and cilantro on fajitas (which I love doing!).

Can I use different tortillas?

Yes, while I use corn tortillas here, you could also use flour tortillas as well! You could also serve this fajita meat and veggies with rice and beans if you are gluten free too.

Can I use another kind of meat?

Yes, you can also make this with chicken or pork too.

How should I store leftovers?

Store leftovers in an airtight container in the fridge. You can easily reheat for a quick and easy meal.
