It might be because we live in Tucson where it’s easier to grill outside than heat up the house, but we love grilling and I love the super easy prep that fajitas need. I added zoodles (zucchini noodles) to my fajitas instead of tortillas a few weeks ago, and… YUM. This recipe makes the best steak fajitas we have had!

To make the zoodles, I use my food processor or a spiralizer.

This recipe for Fajita Zoodles combines my love of Zoodles with my husband’s amazing fajita recipe that we have been making for years. The marinade ingredients might surprise you, but the ingredients are SO delicious together. Trust me on this one.

What kind of meat is best for fajitas?

Something with a bit of fat but not a ton–we love a cut that we get from Costco called loin flap. Other great cuts are flank steak and skirt steak.

I cut the fat off the underside of whatever steak we use. I’ve never thought it was dry or unflavored by doing this, and would much rather trim the fat before we cook it than after it’s cooked.

Ingredients in the Best Steak Fajitas with zoodles: 

  • Steak (we use loin flap, flank steak, or skirt steak from Costco), about 1 pound
  • Like I said, we use different veggies–whatever you love. But our staples are: 1-2 multi-colored bell peppers, an onion, a zucchini, and a package of mushrooms, sliced.
  • Teriyaki Coconut Aminos (you can absolutely use regular teriyaki sauce here, but I highly recommend this coconut one!)
  • pineapple chunks
  • Worcestershire Sauce
  • Montreal Steak Seasoning for the veggies
  • About two tablespoons olive oil for the veggies


As I mentioned, I think this steak fajita recipe is pretty darn perfect–but if you’re wanting more…

  • onion and garlic powder
  • freshly squeezed lime juice
  • cilantro

Instructions for our Steak Fajita Zoodles Recipe:

  1. Mix together pineapple chunks with the teriyaki coconut aminos. If you want to be extra (you do), you’ll want to add in some Worcestershire sauce with your marinade. Mix these ingredients in a small bowl or pour them right into a zipper bag and add the steak in.

2. Slice the veggies that you’re not going to spiralize, then spiralize the veggies you need.

3. Add veggies and a bit of olive oil to a plastic bag. Again–you get extra points if you sprinkle some Montreal steak seasoning in with the veggies. Not sure why these tastes are so perfect together, but they are. Trust me on this one.

4. Grill your veggies for 8-10 minutes on high. Grill your steak on medium high heat for 3-5 minutes per side, or until it’s done.

5. While the grill is going, saute your spiralized veggies in a large skillet over medium heat for 5-10 minutes, being very careful to not overcook them. Watch them while they cook, stirring often.

6. Slice the steak into thin slices, cutting into strips that go against the grain, and serve immediately.

You have some options here for everyone in your family. Another reason why this is the best steak fajita recipe is that you can make fajitas with it (served in small flour tortillas), fajita zoodle bowls (served with zoodles, veggies, and steak fajita meat), burritos (large flour tortillas with veggies and steak), or a steak fajita salad!

Need to cook these steak fajitas on the stove?

No worries! Cook both the steak and veggies in separate skillets over medium high heat. As the veggies are finishing, move them to the side of your pan and add your zoodles in.

Pro cooking tips:

  • On the day that you buy the steak, cut it up and marinate it, then stick it in the freezer. Your steak will be ready to cook in an hour or so after removing it from the freezer and placing it in a sink full of cold water.
  • Spiralizing onions is delicious and I swear it makes the entire meal taste better.
  • If you’re cooking this on the stove, I’d cut your steak in even smaller slices.

Top these fajitas with:

  • sour cream or plain greek yogurt
  • salsa
  • guacamole
  • queso

This one is easy! Fill each container with what you’d like and count accordingly. I add a teaspoon because of the oil I use. My usual container count for this recipe is 2G (one for zoodles, one for fajita veggies), 1R (for meat) and 1 tsp for oil.

  1. Hi Jamie,

    It looks like my formatting is off for some reason… I need to fix it.

    The measurements are AFTER the ingredient. 1 C marinade, 2T Worcestershire sauce, 1T or to taste of Montreal steak seasoning ;) Sorry about that!
