Sheet Pan Shrimp Fajita Tacos Recipe

Sheet pan shrimp fajita tacos roast large shrimp with bell peppers and onion on a single sheet pan at 425 °F for 12 minutes, then fold the mixture into warm corn tortillas with lime crema and cilantro. The dish reduces a multi-pan fajita prep to one sheet — 1 cleanup, 25 minutes total, 4 servings.

A single batch yields 12 tacos in 25 minutes total time, with 10 minutes of prep and 12 minutes of roasting. The shrimp-to-vegetable ratio runs 1.5 lb shrimp to 4 cups sliced peppers and onion at 1.5 oz shrimp + 1/3 cup vegetables per taco.

What Are Sheet Pan Shrimp Fajita Tacos

Sheet pan shrimp fajita tacos are a one-pan adaptation of traditional fajitas, with shrimp and vegetables roasted together at high heat instead of pan-seared in batches. The defining attributes are single-sheet-pan cook, 12-minute roast, fajita-vegetable base (peppers + onion), and a corn tortilla service format.

The "sheet pan" recipe format reached US food-blog popularity around 2015 as an answer to weeknight time pressure. The fajita variant adapts traditional 1980s Tex-Mex fajitas (which originated in Texas border-region restaurants) into the one-pan format. The shrimp version was popularized by Half Baked Harvest, The Defined Dish, and Pinch of Yum starting around 2018.

Sheet pan shrimp fajita tacos retain four traits: 21/25-count shrimp, bell-pepper-and-onion vegetable base, high-heat roast (425 °F), and corn tortilla service.

Ingredients

The recipe uses 1.5 lb shrimp, 4 cups vegetables, and a fajita spice blend. The list below covers exact quantities for 12 tacos.

For the sheet pan

• 1.5 lb large shrimp (21/25 count, peeled and deveined)

• 1 red bell pepper (sliced thin)

• 1 yellow bell pepper (sliced thin)

• 1 green bell pepper (sliced thin)

• 1 large red onion (sliced thin)

• 3 garlic cloves (minced)

• 3 tablespoons olive oil

• 2 tablespoons lime juice

For the fajita spice blend

• 1 tablespoon chili powder

• 1 teaspoon ground cumin

• 1 teaspoon smoked paprika

• 1 teaspoon garlic powder

• 1 teaspoon kosher salt

• 1/2 teaspoon black pepper

• 1/4 teaspoon cayenne pepper

For the lime crema

• 1/2 cup Mexican crema or sour cream

• 1 tablespoon lime juice

• 1/2 teaspoon lime zest

• 1/4 teaspoon kosher salt

For assembly (12 tacos)

• 12 corn tortillas (6-inch)

• 1 avocado (sliced)

• 1/2 cup fresh cilantro (chopped)

• 4 limes (cut in wedges)

• 1/2 cup pico de gallo (optional)

The 425 °F oven temperature is non-negotiable. Lower temperatures produce limp peppers and rubbery shrimp; higher burns the spice rub before the shrimp cook through.

Equipment

The recipe needs 3 pieces of equipment, all standard.

• 1 large rimmed sheet pan (13×18-inch, half-sheet)

• 1 small bowl for the lime crema

• 1 sharp knife and cutting board

A convection oven at 400 °F substitutes for the standard 425 °F. The convection circulation accelerates roasting by 15%.

How to Make Sheet Pan Shrimp Fajita Tacos

The method runs in 3 stages: prep and arrange, roast, assemble. Total active time is 15 minutes.

Stage 1 — Prep and arrange the sheet pan (10 minutes)

Preheat oven to 425 °F. On a large rimmed sheet pan, combine sliced peppers, sliced onion, and 3 minced garlic cloves. Drizzle with 2 tablespoons olive oil. Sprinkle half the spice blend. Toss to coat. Spread in a single layer.

Pat the shrimp dry. In a separate bowl, toss the shrimp with the remaining 1 tablespoon olive oil, the remaining spice blend, and 2 tablespoons lime juice. Set aside.

The vegetables go in first because they need 12 minutes; the shrimp needs only 6 minutes total. Adding shrimp at the start would overcook them.

Stage 2 — Roast (12 minutes)

Roast the vegetables alone for 6 minutes. Remove the pan from the oven. Add the seasoned shrimp on top of the partly-roasted vegetables. Roast 6 more minutes until the shrimp turn opaque and curl into a C-shape.

The two-stage timing prevents shrimp overcooking. Shrimp pass 145 °F internal at 6 minutes in a 425 °F oven; vegetables need 12 minutes for caramelization.

Stage 3 — Mix lime crema and assemble (3 minutes)

Whisk crema, lime juice, lime zest, and 1/4 teaspoon salt in a small bowl. Warm 12 corn tortillas on a comal for 20 seconds per side. Fill each with 1.5 oz shrimp + 1/3 cup roasted vegetables, drizzle with 1 tablespoon lime crema, top with 1 avocado slice, and a pinch of cilantro. Serve with lime wedges.

How to Serve

Serve 3 tacos per person with 1 lime wedge, 1 tablespoon extra lime crema, 2 avocado slices, and 1 tablespoon pico de gallo per plate. The sheet pan can go directly to the table on a trivet — diners assemble their own tacos.

Variations

Three documented variations alter the recipe meaningfully.

• Sheet pan chicken fajita tacos — replaces shrimp with 1.5 lb chicken thigh strips. Cook time extends to 18 minutes total.

• Sheet pan steak fajita tacos — uses 1.5 lb skirt steak strips. Cook time stays 12 minutes; pull at 130 °F internal for medium-rare.

• Sheet pan vegan fajita tacos — replaces shrimp with portobello mushrooms and adds black beans. Heart-of-palm or cauliflower also substitute.

Storage and Reheating

Store cooked vegetables and shrimp separately for 2 days refrigerated. Never freeze cooked shrimp. Reheat shrimp in a skillet for 60 seconds with 1 teaspoon water; vegetables in a 400 °F oven for 4 minutes.

Pre-sliced raw vegetables keep 3 days refrigerated; pre-mixed spice rub keeps 6 months in an airtight jar.
