Ingredients

For the Sheet Pan Shrimp Fajitas:

1 pound mini bell peppers, stem removed and thinly sliced into rounds
1 cup halved and thinly sliced red onion (½ large onion)
1 serrano pepper, stem removed and thinly sliced into rounds (optional)
4 tablespoons avocado oil, divided
2 teaspoons Kosher salt, divided
1 teaspoon freshly ground black pepper, divided
1 ½ pounds peeled, deveined, and tail-off shrimp (36/40)
2 teaspoons chili powder
1 teaspoon garlic powder
1 teaspoon smoked paprika
½ teaspoon ground cumin
1 tablespoon finely chopped fresh oregano leaves
Zest of ½ lime

For Serving:

10 flour tortillas
2 avocados, mashed
¼ cup freshly chopped cilantro leaves
Salsa, for topping
1 lime, cut into wedges

Directions

Make the Shrimp Fajitas:

Preheat the oven to 425°F. Line a sheet pan with parchment paper.
Place the sliced bell peppers, onion, and serrano pepper on the prepared sheet pan. Drizzle with 2 tablespoons of avocado oil, ½ teaspoon Kosher salt, and ½ teaspoon black pepper. Toss until well combined, then spread into an even layer. Par cook in the oven for 10 minutes until softened.
Meanwhile, pat the shrimp very dry and place in a bowl. Add the remaining 2 tablespoons avocado oil, 1 ½ teaspoons Kosher salt, ½ teaspoon black pepper, chili powder, garlic powder, smoked paprika, cumin, fresh oregano, and lime zest. Toss until well combined and the shrimp is evenly coated. Set aside.
Remove the veggies from the oven and add the shrimp to the pan. Toss everything together and spread into an even layer. Return to the oven and roast for 10 more minutes, until the shrimp is cooked through.

Assemble the Tacos:

Heat a dry stainless steel skillet over medium heat. One at a time, warm the tortillas for about 30 seconds per side. Alternatively, char the tortillas directly over a gas flame using tongs for a few seconds.
To serve, spread mashed avocado on a tortilla, then top with shrimp fajitas. Garnish with cilantro, salsa, and a squeeze of lime juice. Enjoy!

The Secret to Perfect Shrimp Fajitas

For the best shrimp fajitas, a few key techniques help maximize flavor and texture:

Use fresh shrimp: Fresh or high-quality frozen shrimp make a big difference in taste and texture. Look for peeled, deveined shrimp with tails removed for easy eating.
Dry the shrimp well: Patting the shrimp dry before seasoning helps them roast properly instead of steaming.
Season generously: A blend of chili powder, smoked paprika, cumin, garlic powder, and fresh oregano ensures deep, rich flavors in every bite.
Roast at high heat: Cooking the shrimp and vegetables at 425°F allows them to caramelize and develop a slightly charred, smoky flavor.
Use lime zest instead of just juice: Lime zest adds a more concentrated citrus flavor that enhances the shrimp without making them watery.

The Best Vegetables for Shrimp Fajitas

The combination of bell peppers and onions is a classic choice for fajitas, but you can easily switch things up to suit your preferences. Here’s what each vegetable brings to the dish:

Bell peppers: Sweet and slightly crisp, bell peppers balance out the smoky, spicy flavors of the shrimp. Mini bell peppers are ideal for quick roasting.
Red onion: Adds a mild sharpness and caramelizes beautifully when roasted.
Serrano pepper: Brings a little heat to the dish. If you prefer milder fajitas, you can omit it or substitute with a mild poblano pepper.
Zucchini or mushrooms: If you want to add more variety, zucchini or mushrooms roast well and complement the other ingredients.

Choosing the Best Tortillas

Tortillas are an essential part of any taco, and the type you choose can influence the texture and flavor of the final dish.

Flour tortillas: Soft and flexible, these are great for holding all the juicy fillings. They also crisp up nicely when lightly toasted.
Corn tortillas: More traditional and slightly firmer, corn tortillas provide a slightly earthy flavor that complements the roasted shrimp and peppers.
Low-carb or whole wheat tortillas: A great option for those looking to make the dish a little healthier.

For the best results, warm the tortillas before serving—either by toasting them in a dry skillet or charring them directly over a gas flame for extra smokiness.

Toppings to Elevate Your Shrimp Fajita Tacos

Toppings add freshness, creaminess, and extra layers of flavor. Here are some of the best options:

Mashed avocado: Provides a creamy contrast to the smoky shrimp and veggies.
Fresh cilantro: Adds brightness and a fresh, herby finish.
Salsa: A spoonful of homemade or store-bought salsa brings a juicy, tangy kick.
Sour cream or Greek yogurt: A cooling element that balances the spice.
Pickled red onions: Adds a bit of acidity and crunch.
Lime wedges: A squeeze of fresh lime juice ties everything together.
Cotija cheese or queso fresco: A salty, crumbly cheese that enhances the flavors.

How to Store and Reheat Leftovers

If you have leftovers, don’t worry—these fajitas reheat beautifully.

Refrigeration: Store cooked shrimp and vegetables in an airtight container in the refrigerator for up to 3 days.
Freezing: While shrimp is best enjoyed fresh, you can freeze the roasted vegetables for up to 2 months. Thaw in the refrigerator before reheating.
Reheating: Warm leftovers in a skillet over medium heat for 3-4 minutes or in the oven at 350°F for 10 minutes. Avoid microwaving shrimp for too long, as it can become rubbery.

Customizing Your Shrimp Fajita Tacos

These tacos are incredibly flexible, so you can easily adapt them to your dietary needs and preferences.

Make it spicier: Add extra serrano peppers, cayenne pepper, or a drizzle of hot sauce.
Try a different protein: Swap out the shrimp for chicken, steak, tofu, or even roasted chickpeas for a vegetarian option.
Go low-carb: Serve the shrimp and vegetables in lettuce wraps instead of tortillas.
Add more veggies: Roasted zucchini, mushrooms, or sweet corn can add extra depth and texture.
Use different cheeses: Instead of cotija, try shredded Monterey Jack, cheddar, or a melty cheese blend.

Why These Tacos Are Great for Meal Prep

If you’re looking for an easy meal prep recipe, these shrimp fajitas are a fantastic choice.

Prep ahead: Slice the peppers and onions, and marinate the shrimp a day in advance for quicker cooking.
Portion out meals: Store in meal prep containers with rice or tortillas for grab-and-go lunches.
Reheat-friendly: Shrimp reheats quickly, making it a convenient protein option for busy schedules.

Perfect Side Dishes for Shrimp Fajita Tacos

While these tacos are a complete meal on their own, pairing them with a side dish can make the meal even more satisfying. Here are some great options:

Mexican rice: A classic side that complements the smoky, spicy flavors.
Black beans or refried beans: Adds extra protein and a creamy texture.
Grilled corn (elote): Sweet, smoky, and slightly charred corn on the cob pairs beautifully.
Chips and guacamole: A simple, crowd-pleasing side dish.
Mexican slaw: A crunchy cabbage slaw with lime dressing adds freshness.
