Healthy, gluten-free Tex Mex with Sheet Pan Salmon Fajitas
Fajitas are a popular dish in Mexican cuisine. Fajitas are versatile, simple, and flavorful - everything we love in a meal prep recipe! As you know, we make delicious meals more nutritious and diet-inclusive. Today, we're doing that with fajitas -- presenting you with Sheet Pan Salmon Fajitas!
The fajitas dish history dates back to the 1930s and 40s when cowboys led the wild west of Texas. However, credit for the creation of fajitas goes to the Mexican ranch workers along the Rio Grande. Ranch workers received partial payment for their work in the form of food. After a day's work, ranchers received skirt steak - the toughest and least desirable part of a butchered steer. The workers made the best of the meat by cooking it up and serving it on a flour tortilla with onions and peppers. The term "fajita" comes from "faja," meaning belt or girdle - in this case, skirt. As time went on, fajitas turned into anything with meat and peppers stuffed in a flour tortilla. But today's fajitas sheet pan meal prep idea is gluten-free, so no flour tortillas here. We also swapped skirt steak for a juicy cut of salmon. Technically, these aren't fajitas -- but we won't tell if you don't.
This sheet pan style fajita recipe adds a dose of healthy fats thanks to salmon along with antioxidant-rich veggies for a complete meal with easy cleanup!
How long will Sheet Pan Salmon Fajitas last for?
When properly stored, Sheet Pan Salmon Fajitas will last for 3 to 4 days. Both the cooked salmon and vegetables will last at least 3 days in the refrigerator, so you can store them together. Store cooked salmon and vegetables in a shallow plastic airtight container. You can also portion the salmon and veggies to wrap in aluminum foil packets.
Can Sheet Pan Salmon Fajitas be frozen?
Yes, you can freeze this sheet pan meal prep idea. Cooked salmon will last for 6-9 months in the freezer, no problem. If you plan on freezing this recipe, don't cook the vegetables all the way; you want them to still have their crunch when freezing. Since this is a sheet pan recipe and everything is cooked together, it's best if you only freeze the cooked salmon. Wrap each piece of salmon on parchment paper and store them in a freezer bag.

Other tips for making Sheet Pan Salmon Fajitas:
- As with any sheet pan recipe, do not overcrowd the pan. Doing so results in unevenly cooked food.
- If you want to char your vegetables, check the salmon first. Thoroughly cooked salmon is flaky with an internal temperature of 145 degrees.
- If you plan on freezing this recipe, make sure the salmon is completely cooled - no steam should be coming from it. Steam evaporating from the fish creates moisture, leading to bacteria. Thaw frozen salmon in the refrigerator for a few hours to overnight when you're ready to eat.
