Sheet Pan Shrimp Fajitas are an easy and tasty way to bring a little zest to your dinner table. Juicy shrimp, colorful bell peppers, and onions all roasted together on one pan, seasoned with a blend of smoky and spicy flavors that make every bite a little celebration.
I love how this recipe saves me time without skimping on flavor. Tossing everything on a sheet pan means less mess and more time to relax or get other things done. Plus, shrimp cooks so fast that dinner comes together in no time, which is perfect for busy weeknights.
My favorite way to enjoy these fajitas is wrapped in a warm tortilla with a squeeze of lime and a dollop of creamy guacamole or sour cream. It feels fresh and satisfying, and the bright, roasted veggies give a nice crunch that makes it all the more enjoyable. I promise, once you try this, it might become your go-to dinner too!
Key Ingredients & Substitutions
Shrimp: Fresh or frozen shrimp work great here. If frozen, just thaw and pat dry before cooking. For a twist, try using scallops or sliced chicken breast instead.
Bell Peppers: Red, yellow, and green peppers give a nice color and mix of sweetness. You can swap with poblano or Anaheim peppers for a bit more heat.
Onions: White onions add a sharp but mild flavor. Yellow or red onions are good substitutes if you like a sweeter or stronger taste.
Spices: Chili powder, cumin, and smoked paprika create the classic fajita flavor. Feel free to adjust the cayenne for less or more heat. If you don’t have smoked paprika, regular paprika works fine.
Tortillas: Flour tortillas are smooth and soft, but corn tortillas add a nice texture and are gluten-free. Both work equally well to wrap these fajitas.
How Do You Get the Shrimp and Veggies Cooked Perfectly Together?
This recipe is all about timing since shrimp cooks faster than veggies. Here’s how to nail it:
- Slice peppers and onions thinly so they cook evenly and quickly with the shrimp.
- Spread veggies out on the pan in a single layer for even roasting and some crispy edges.
- Add shrimp last and arrange them on top so they roast quickly without drying out.
- Keep the oven hot at 400°F to get a quick roast, so veggies stay tender-crisp and shrimp stays juicy.
- Check shrimp at 10 minutes and pull the pan out once they turn pink and curl slightly—overcooked shrimp become rubbery.
Following these tips helps you enjoy juicy shrimp and nicely roasted veggies at the same time with minimal fuss.

Equipment You’ll Need
- Large baking sheet – I use this because it fits everything in a single layer for even roasting.
- Mixing bowls – helpful for tossing spices and vegetables so everything gets coated evenly.
- Measuring spoons – to keep the spice mix just right without guessing.
- Oven mitts – safety first when handling hot sheets out of the oven!
- Sharp knife & cutting board – for slicing bell peppers and onions safely and evenly.
Flavor Variations & Add-Ins
- Protein swaps: Try sliced chicken or scallops instead of shrimp for a different flavor.
- Cheese: Sprinkle shredded cheese like Monterey Jack or queso fresco after roasting for a creamy touch.
- Veggie ideas: Add sliced zucchini, mushrooms, or cherry tomatoes for extra color and flavor.
- Spice tweaks: Use chipotle powder or add a dash of hot sauce before serving for more heat.

Step-by-Step Instructions:
1. Prepare the Oven and Pan:
Preheat your oven to 400°F (200°C). Line a large sheet pan with parchment paper or lightly grease it to prevent sticking.
2. Make the Spice Mix and Toss Veggies:
Mix olive oil, chili powder, smoked paprika, cumin, garlic powder, onion powder, cayenne pepper (if using), salt, and pepper in a large bowl. Add the sliced bell peppers and onion rings, then toss them well to coat evenly with the spices.

Evenly spread the spiced peppers and onions over the prepared sheet pan in a single layer for roasting.
4. Season and Arrange the Shrimp:
In the same bowl, add the shrimp and toss to coat with any remaining spice mix and oil. Arrange the shrimp evenly over the vegetables on the sheet pan.
5. Roast Everything:
Place the sheet pan in the oven and roast for 10-12 minutes, or until the shrimp are pink and cooked through, and the vegetables are tender with a bit of a char.
6. Finish and Serve:
Remove from the oven, squeeze fresh lime juice over the shrimp and veggies, and sprinkle with chopped cilantro. Serve immediately with warm tortillas and lime wedges. Add sour cream, guacamole, or salsa if you like!
Can I Use Frozen Shrimp for This Recipe?
Yes! Just make sure to fully thaw the shrimp before cooking. Thaw them overnight in the fridge or quickly under cold running water. Pat them dry to avoid extra moisture on the baking sheet.
How Can I Store Leftovers?
Store any leftover shrimp fajitas in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave to keep the shrimp tender and veggies flavorful.
Can I Make This Recipe Spicier or Milder?
Absolutely! Adjust the cayenne pepper to your heat preference or swap it for a milder paprika if you prefer less spice. You can also add fresh jalapeño slices for extra kick.
What Are Good Side Dishes to Serve with Sheet Pan Shrimp Fajitas?
Rice, black beans, or a fresh salad all pair beautifully. For a low-carb option, serve with cauliflower rice or extra guacamole and sliced avocado.
