Flavorful Fajita Ingredients

  • Shrimp: Larger shrimp make for a better presentation, but you can use any size you like. Frozen shrimp should be thawed first.
  • Veggies: Colorful bell peppers and sweet onions are classic fajita fillers, but you can use any keto-friendly veggie, even leftovers from the fridge. Leftover mushrooms or zucchini make great additions to sheet pan shrimp fajitas. You might need extra seasoning to properly coat any additional ingredients.
  • Fajita Seasonings: Buy or DIY? My homemade fajita seasoning in the recipe notes below is made with basic pantry ingredients that are likely already on hand. Adjust the amount of chili powder for milder or spicier fajitas. Feel free to swap out ingredients to make a signature blend.
  • Flavor Twists: Besides low-carb tortillas, pack on the protein and serve shrimp fajitas with cottage cheese flatbread or use butter lettuce leaves.

How To Make Sheet Pan Shrimp Fajitas

  1. Toss: Spread veggies on pan, season, and roast (full recipe below).
  2. Add: Add the seasoned shrimp to the center of the pan and continue roasting.
  3. Combine: Mix cooked shrimp and veggies before serving.
  4. Serve: Prepare a platter of toppings such as sour cream, guacamole, salsa, shredded cheese, and a little cilantro.

Speedy Sheet Pan Secrets

  • For crispy-edged shrimp, add ½ teaspoon of baking powder to the fajita seasoning mix.
  • Line the baking sheet with parchment paper for faster cleanup.
  • If necessary, use two sheet pans to avoid overcrowding.

  • Freeze portions in zippered bags for up to 3 months, and thaw overnight in the refrigerator before reheating. Scoop leftovers onto a bed of greens for a quick and wholesome workday lunch.
