Keto Steak Fajitas

We have made these several different ways, you choose which one is your favorite. If it is hot outside and you don’t want to use your oven for this version you can try our Instant Pot fajitas

BUT the “old fashioned” oven is still a fave among many so we wanted to offer this way too. All of them have lots of vegetables mixed in but this one has the most, including potatoes! You can leave those out to be more keto friendly if you like, or just let the kiddos enjoy them.

Beef Fajitas in the Oven

Low carb lunches such as this one are great. They’re packed with protein to keep you full, but not shy on flavor. 

There are many ways to season your meat. For a simple sprinkle you can just add a little salt and pepper. If you want to go beyond that we have a light dry rub for beef below. Then marinade overnight and then continue on to finish the recipe as directed.

With any of these options comes the heat factor. We prefer ours to be in the mild/medium range but you can really pack on the spices if you’re daring. 😉

Best Way to Cook Fajitas in the Oven

Pre-cook your potatoes, either by boiling them for 15 minutes, or by poking holes in the skins with a fork and microwaving for 7 – 10 minutes.

  1. Grease a large sheet pan sprayed with cooking spray. Slice cooked potatoes in half, place cut side down on sheet pan.
  2. In a large bowl, toss broccoli with 2 tbs soy sauce and 1 tbs olive oil. Lay them on top.
  3. Slice peppers and arrange on sheet pan. Spray lightly with oil. Arrange mushrooms on sheet pan, spray lightly with oil and then sprinkle with seasoned salt.
  4. Arrange onion slices on sheet pan, spray lightly with oil and season with chili powder, cumin, seasoned salt and any others you like.
  5. Slice your meat into small slices. (don’t use frozen steak for this) In a large bowl toss with 1 tbs olive oil, 1 tsp cumin, 1 tsp minced garlic (about 1 clove), 1/2 tsp oregano, 1/4 tsp salt.
  6. Spread onto your sheet pan in a single layer.
  7. Cook under a high broiler for 5-7 minutes, then flip steak and onions. Cook another 5-7 minutes or just until meat is cooked.
  8. Pay attention to where your broiler is mine is always hottest in the center, so I put more hearty items in the center of the pan.

If you want to make sheet pan chicken fajitas you could follow this recipe too, you just may need to adjust time to a bit less and ensure chicken is cooked through before consuming.

Just use boneless skinless chicken breasts and cut into thin strips, marinate and add chicken and vegetables to sheet pan as directed.

Oven Fajitas Chicken

You could add strips of chicken too alternatively. Either way warm tortillas on the stovetop or microwave and serve with meat and vegetables inside. Or just eat as is or served on top of a bed of Instant Pot white rice for a gluten free option. Total cook and prep time should be around 30 minutes from start to finish. 

What’s great about these sheet pan steak fajitas is there are so many options when it comes to a dry rub or beef marinade. Use your own secret recipe if you have one, or use ours. When you’re using beef you can also make it as “well done” or rare as you want.
