Ingredients

Fajita Ingredients

• Shrimp: Use fresh shrimp or thawed frozen shrimp, peeled and deveined, for the easiest prep. Shrimp is a lean, protein-rich seafood that cooks quickly and pairs perfectly with bold fajita seasoning. 

• Bell peppers: Red, yellow, or orange bell peppers work best here as they’re sweeter and hold up well in the oven, but a green pepper works too if that’s what you have on hand! Sliced thin so they cook evenly alongside the shrimp.

• Red onion: Adds a savory, slightly sweet flavor and a pop of color. Sliced thin as well, so it softens nicely in the oven.

• Extra virgin olive oil: Helps everything roast evenly and adds heart-healthy fats to the mix. Use extra virgin olive oil for the highest quality!

Fajita Seasoning

• Salt and black pepper: The base of any good seasoning blend.
• Chili powder: Brings warmth and that classic fajita flavor.
• Garlic powder: Adds savory depth without the need to mince fresh garlic.
• Onion powder: Rounds out the savory notes in the seasoning blend.
• Ground cumin: Earthy and warm, a key player in that signature fajita taste.
• Smoked paprika: Adds a subtle smoky flavor that takes these fajitas to the next level.

Note: you can use a pre-made fajita seasoning mix if you’re short on time! My favorite is the Siete brand.

How to Make It

Step One: Preheat and Prep.

Preheat your oven to 450°F. Prep time is minimal here! Slice the bell peppers and red onion thin and add them to a large mixing bowl along with the peeled and deveined shrimp.

Step Two: Season Everything.

Drizzle the olive oil over the shrimp and veggies, then add all of the seasoning ingredients: salt, black pepper, chili powder, garlic powder, onion powder, cumin, and smoked paprika. Toss everything together until the shrimp and vegetables are evenly coated.

Step Three: Spread and Bake.

Spread the mixture out in a single layer on a greased or parchment paper lined baking sheet. Bake for 8 minutes, then switch the oven to broil and broil for an additional 2 minutes, or until the shrimp are cooked through and the edges of the peppers are slightly charred.

Tip: Make sure the shrimp and veggies are spread in a single layer without too much overlap. Crowding the pan can cause them to steam rather than roast during the cooking process, which means less caramelization and flavor.

Step Four: Garnish and Serve.

This shrimp fajita recipe comes together so quickly- just remove from the oven, pile the fajita veggies and juicy shrimp onto warm tortillas, and finish with a squeeze of fresh lime juice and a handful of fresh cilantro.

Tips, Variations, and Substitutions

• Not a shrimp fan? This recipe works great with sliced chicken breast or steak. Just note that cooking times will be longer: chicken should reach an internal temperature of 165°F.
• Add a pinch of cayenne pepper or red pepper flakes to the seasoning mix for extra heat.
• Frozen shrimp works perfectly here. Just make sure to thaw completely and pat dry before seasoning, excess moisture will prevent them from roasting properly.
• Want a low-carb version? Skip the tortillas and serve the fajita mixture over cauliflower rice or in lettuce cups for a lighter option.
• Add more veggies such as zucchini, corn, or jalapeño slices, which are great additions that roast well at the same temperature.
• This recipe is naturally gluten-free, just double-check your seasoning ingredients and serve with certified gluten-free tortillas if needed.
• Hosting a crowd? Sheet pan fajitas are easy to scale up; just use two baking sheets and rotate them halfway through baking to ensure even roasting.
• Meal prep tip: Store the cooked shrimp and veggies separately from your tortillas or rice to keep everything fresh throughout the week.

How to Store It

Store leftover shrimp fajita filling in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet over medium heat for best results, or microwave in short intervals until warmed through.

Shrimp does not freeze well once cooked, as the texture can become rubbery after thawing. For best results, enjoy this one fresh or within a few days of making it.

How to Serve It

Sheet pan shrimp fajitas make a delicious dinner no matter how you serve them. Load them up with your favorite fajita toppings and enjoy any of these easy serving ideas:

• Classic fajitas: Serve in warm flour or corn tortillas topped with sour cream, guacamole, salsa, or shredded cheese.
• Fajita bowl: Spoon over cilantro lime rice or brown rice  with a side of black beans for a filling, balanced bowl.
• Nachos: Layer over tortilla chips with shredded cheese and broil for a few minutes for sheet pan shrimp nachos — great for a crowd.
• Burrito: Wrap it all up in a large flour tortilla with rice, beans, and your favorite toppings for a hearty burrito.
• Low carb option: Serve over cauliflower rice or in romaine lettuce cups to keep it lighter without sacrificing flavor.
