Sheet-Pan Shrimp Fajitas with Peppers is a simple, colorful dish that brings together juicy shrimp, sweet bell peppers, and zesty spices all cooked on one pan. The shrimp get perfectly tender while the peppers turn soft and slightly caramelized, making every bite full of bold flavors and great textures. It’s a quick and easy meal that feels like a little fiesta on your plate.
I love making this recipe when I want something fresh and fast, but still satisfying. The best part is how everything roasts together on the sheet pan, so there’s barely any cleanup afterward. I usually sprinkle some fresh lime juice and chopped cilantro on top right before serving — it brightens up the whole dish and makes it taste even better. Plus, the smell while it’s cooking is amazing and always makes me hungry.
My favorite way to eat these shrimp fajitas is wrapped in warm tortillas with a spoonful of sour cream or guacamole, but they’re just as tasty over a bed of rice or alongside a simple salad. Whenever I make them for friends, everyone asks for the recipe because it’s so easy and delicious. It’s definitely one of those meals I keep coming back to when I want good food without a lot of fuss.
Key Ingredients & Substitutions
Shrimp: Large shrimp work best here since they cook quickly and stay juicy. If you prefer, you can swap in scallops or firm white fish like cod for a tasty change.
Bell Peppers: Red and yellow peppers add sweetness and color. Feel free to add green peppers or use any color you enjoy. If peppers aren’t your thing, zucchini or sliced mushrooms make great alternatives.
Spices: Chili powder, paprika, cumingive this fajita the classic smoky flavor. If you don’t have all these spices, a pre-made fajita or taco seasoning blend also works well.
Lime and Cilantro: These fresh touches brighten the dish. If you aren’t a fan of cilantro, parsley is a nice substitute. Lime juice is key but lemon juice can be used if needed.
How Do You Make Sure the Shrimp Stay Tender and Don’t Overcook?
Shrimp cook very quickly, so it’s important to keep an eye on them in the oven. Here’s what helps:
- Cut shrimp tails if needed and toss shrimp with oil and seasoning first—this protects them from drying out.
- Slice peppers and onions thinly so everything roasts evenly.
- Spread all ingredients out in a single layer on the pan to allow even cooking and caramelization.
- Roast at a hot temperature (425°F) but only for 10-12 minutes to keep shrimp juicy.
- Watch the shrimp—they should turn pink and curl into a loose “C” shape. Overcooked shrimp curl tightly and become rubbery.
- Finish with lime juice and fresh herbs after baking to keep flavors bright and fresh.
With these steps, your shrimp fajitas will be tender, flavorful, and perfectly cooked every time.
Equipment You’ll Need
- Large baking sheet – I like this because it allows everything to roast evenly and makes cleanup easy.
- Mixing bowls – helps you toss the shrimp and peppers with the seasoning smoothly.
- Measuring spoons – keeps your spices just right for the perfect flavor.
- Sharp knife and cutting board – for slicing peppers and onions safely and neatly.
- Cooking tongs – great for spreading and serving the roasted ingredients without breaking them apart.
Flavor Variations & Add-Ins
- Use chicken or beef strips instead of shrimp for a different protein twist.
- Add sliced mushrooms or zucchini for more veggies and texture.
- Sprinkle shredded cheese like Monterey Jack or cheddar on top after roasting for extra creaminess.
- Mix in a teaspoon of smoked paprika or chipotle powder for a smoky, spicy flavor boost.

Step-by-Step Instructions:
1. Prepare Your Oven and Pan:
Preheat your oven to 425°F (220°C). Line a large sheet pan with parchment paper or lightly grease it to prevent sticking.
2. Mix the Seasoning:
In a large mixing bowl, combine the olive oil, chili powder, paprika, cumin, garlic powder, cayenne pepper (if using), salt, and black pepper. Stir well to make a flavorful spice mix.
3. Toss Shrimp and Veggies:
Add the peeled shrimp, sliced red, yellow (and green if using) bell peppers, and sliced red onion to the bowl. Toss everything together until all pieces are evenly coated with the seasoning mixture.
4. Arrange on the Sheet Pan:
Spread the shrimp and vegetable mix in an even, single layer on your prepared sheet pan. This helps everything cook evenly and get nice caramelization.

Can I Use Frozen Shrimp for This Recipe?
Yes, you can! Just be sure to thaw the shrimp completely before cooking. The best way is to leave them in the fridge overnight or place them in a sealed bag and submerge in cold water for about 20 minutes. Pat dry before seasoning to avoid excess moisture.
Can I Make This Ahead of Time?
Absolutely! You can prep and season the shrimp and veggies a few hours ahead, then keep them covered in the fridge until ready to roast. Cook just before serving for the best texture and flavor.
How Do I Store and Reheat Leftovers?
Store leftover fajita mixture in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over medium heat or in the microwave until warmed through. Add a splash of lime juice or oil to refresh the flavors.
Can I Add Other Vegetables?
Definitely! Feel free to add mushrooms, zucchini, or cherry tomatoes to the sheet pan for extra variety. Just slice them similarly to the peppers so everything cooks evenly.
