To create Sheet Pan Steak and Shrimp Fajitas, gather the following ingredients:

  • 1 pound flank steak, thinly sliced
  • 1 pound large shrimp, peeled and deveined
  • 3 bell peppers (red, yellow, and green), sliced
  • 1 red onion, thinly sliced
  • 3 cloves garlic, minced
  • 2 tablespoons fajita seasoning
  • 3 tablespoons olive oil
  • Juice of 1 lime
  • Flour or low-carb tortillas (for serving)
  • Fresh cilantro, sliced jalapeños, and lime wedges (for garnish)


1. Preheat and Prepare:

  • Preheat your oven to 400°F (200°C) and line a large sheet pan with aluminum foil or parchment paper for easy cleanup.

2. Marinate the Steak and Shrimp:

  • In a large mixing bowl, combine the thinly sliced flank steak and peeled shrimp.
  • Add minced garlic, fajita seasoning, olive oil, and the juice of one lime to the bowl.
  • Toss the ingredients to ensure the steak and shrimp are well coated with the marinade.
  • Allow the mixture to marinate for 15-30 minutes while you prepare the vegetables.

3. Slice the Vegetables:

  • Slice the bell peppers and red onion into thin strips. These vibrant vegetables will add both color and flavor to your fajitas.

4. Arrange on the Sheet Pan:

  • Spread the marinated steak and shrimp, along with the sliced bell peppers and red onions, evenly on the prepared sheet pan. Make sure everything is spread out to allow for even cooking.

5. Roast to Perfection:

  • Roast the ingredients in the preheated oven for about 10-12 minutes or until the steak is cooked to your desired level of doneness, and the shrimp turns pink and opaque.

6. Serve with Tortillas:

  • Warm the tortillas according to the package instructions.
  • Serve the cooked fajita mixture on the tortillas and garnish with fresh cilantro, sliced jalapeños, and lime wedges.

Cooking Notes

  • To ensure the steak and shrimp cook evenly, it’s essential to spread them out on the sheet pan without overcrowding.
  • You can adjust the level of spiciness by adding more or less fajita seasoning or jalapeños to suit your taste.


  • Get creative with your fajita toppings by adding grated cheese, diced tomatoes, or a dollop of sour cream for extra creaminess.
  • Experiment with different protein options like chicken or tofu for a unique twist on traditional fajitas.
