Sheet Pan Shrimp Fajitas are a quick and tasty way to enjoy all the flavors of classic fajitas without a lot of fuss. Juicy shrimp, colorful bell peppers, and onions all roast together on one pan, making cleanup a breeze and the cooking process super straightforward. The mix of spices adds a zesty kick that really brings everything alive.
I love making these fajitas when I want something easy but still packed with flavor. The shrimp cook so fast on the sheet pan, which means dinner comes together in no time. Plus, the smell of the sizzling peppers and onions always makes the kitchen feel cozy and inviting. I usually toss everything in some lime juice at the end to brighten up the flavors even more.
One of my favorite ways to eat these fajitas is wrapped in warm tortillas with a dollop of sour cream or a sprinkle of cheese. Sometimes I add a little guacamole or fresh cilantro for a fresh touch. It’s perfect for a simple weeknight dinner or even a fun weekend meal with friends. I’m pretty sure this dish will quickly become a go-to in your kitchen like it is in mine!
Key Ingredients & Substitutions
Shrimp: Fresh or frozen shrimp work well, but thaw frozen shrimp first. If you prefer, use peeled and deveined chicken strips as a tasty swap.
Bell Peppers: The mix of red, yellow, and green peppers gives great color and mild sweetness. Feel free to use only one or two colors or add poblano peppers for a bit more heat.
Spices: Chili powder, smoked paprika, and cumin create the fajita flavor. If you don’t have smoked paprika, regular paprika or chipotle powder are good alternatives.
Lime & Cilantro: Lime adds fresh brightness, and cilantro gives an herbal kick. You can skip cilantro if you’re not a fan or substitute fresh parsley.
How Do I Get Perfectly Cooked Shrimp and Veggies on One Sheet Pan?
The key to success is even slicing and timing. Cut peppers and onions into strips of similar thickness so they cook evenly with the shrimp.
- Spread everything in a single layer on the pan so the shrimp don’t steam but roast nicely.
- Watch the shrimp closely—12 to 15 minutes at 400°F usually cooks them just right. Overcooked shrimp turn tough quickly.
- After baking, squeeze fresh lime juice right away to uplift the flavors before serving.
This method keeps your shrimp juicy and your vegetables tender-crisp, making every bite delicious!

Step-by-Step Instructions:
1. Prepare Your Oven and Sheet Pan:
Preheat your oven to 400°F (200°C). Lightly grease a large sheet pan or line it with parchment paper to keep things from sticking and to make clean-up easier.

In a large bowl, combine the shrimp, red, yellow, and green bell peppers, and sliced onion. Make sure they’re all sliced similarly for even cooking.
3. Add the Seasoning:
In a smaller bowl, mix olive oil with chili powder, smoked paprika, ground cumin, garlic powder, onion powder, cayenne pepper (if using), salt, and pepper. Pour this mixture over the shrimp and vegetables, then toss gently but well so everything is evenly coated with the spices.
