Sheet-Pan Shrimp Fajitas with Peppers are an easy and flavorful meal that’s perfect for busy nights. The shrimp cook quickly alongside colorful bell peppers and onions, all seasoned with simple spices that bring a warm, zesty kick. Everything cooks together on one tray, making clean-up a breeze!
I love how quickly this comes together—it’s a great go-to when I want something tasty but don’t feel like spending a lot of time in the kitchen. I usually serve these with warm tortillas and a squeeze of fresh lime, plus a little dollop of sour cream or guacamole if I have it on hand. The shrimp stay juicy, and the peppers get slightly caramelized and sweet, which balances the spices nicely.
This dish always brings a little fiesta to our dinner table, and it’s a crowd-pleaser because the flavors are simple but really punchy. I find it’s a great way to get some veggies in without any fuss, and everyone loves piling their own fajitas with toppings. Plus, since it all cooks on one pan, I can spend more time enjoying my meal and less time washing dishes!
Key Ingredients & Substitutions
Shrimp: Fresh or frozen shrimp work well here. If frozen, thaw completely and pat dry for best results. You can swap shrimp for chicken strips or firm tofu if you prefer a different protein.
Bell Peppers: Red, yellow, and orange peppers add sweetness and color. You can use green bell peppers if that’s what you have, but they’re a bit more bitter. Mix and match to your taste!
Spices: Chili powder, smoked paprika, and cumin give this dish its classic fajita flavor. If you don’t have smoked paprika, regular paprika is fine. For less heat, skip or reduce the cayenne pepper.
Avocado and Lime: These fresh toppings balance the spices and add creaminess and brightness. You can substitute lime with lemon if needed, but lime is traditional in fajitas.
How Do You Get Perfectly Cooked Shrimp and Veggies on One Pan?
Since shrimp cooks faster than peppers and onions, keep these tips in mind:
- Cut peppers and onions into similar thin strips for even cooking.
- Spread veggies on one side of the pan, shrimp on the other, so you can remove the shrimp earlier if needed.
- Roast at 400°F for 8-10 minutes—shrimp turn pink and curl when done.
- If veggies aren’t quite tender, leave them a few minutes longer but watch shrimp closely to avoid overcooking.
- Stir veggies halfway through cooking for even roasting and slight char.
These simple steps help the shrimp stay juicy while the peppers and onions get tender and flavorful without burning. It’s a balanced, easy sheet-pan meal!
Equipment You’ll Need
- Large sheet pan – I like it because everything cooks evenly and makes cleanup quick.
- Mixing bowls – for tossing the vegetables and shrimp with spices and oil.
- Measuring spoons – to add precise amounts of spices and oil.
- Cutting board and knife – for slicing peppers, onions, and prepping the shrimp.
- Cooking spoons or tongs – for tossing and serving the ingredients.
Flavor Variations & Add-Ins
- Use sliced chicken breast or steak strips instead of shrimp for different protein options.
- Add sliced mushrooms or zucchini to the vegetables for extra veggies.
- Sprinkle with shredded cheese or crumbled queso for a cheesy twist.
- Mix in spices like cumin and coriander for a slightly different flavor profile.

How Much Time Will You Need?
This recipe takes about 10 minutes to prep and 8-10 minutes to roast in the oven. So in under 20 minutes, you’ll have a flavorful and colorful meal ready to enjoy!
Step-by-Step Instructions:
1. Prep the Oven and Vegetables
Preheat your oven to 400°F (200°C). Line a large sheet pan with parchment paper or lightly grease it to prevent sticking. In a large bowl, toss the sliced bell peppers and red onion with 2 tablespoons of olive oil, plus a pinch of salt and pepper. Spread these veggies evenly on one side of your sheet pan.
2. Season the Shrimp
Using the same bowl, combine the shrimp with the remaining 1 tablespoon of olive oil, chili powder, smoked paprika, cumin, garlic powder, cayenne pepper (if you like a little heat), salt, and pepper. Toss well so each shrimp is nicely coated.
3. Arrange and Roast
Place the shrimp on the empty side of the sheet pan, keeping them separate from the vegetables. Roast everything in the oven for 8 to 10 minutes. You’ll know the shrimp are done when they turn pink and curl up, and the peppers and onions will be tender with some nice charred edges.
4. Garnish and Serve
Remove the sheet pan from the oven. Sprinkle fresh cilantro over the shrimp and veggies. Serve immediately with lime wedges, sliced avocado, and warm tortillas. Each person can make their own fajita with all the tasty ingredients you prepared—enjoy!
Can I Use Frozen Shrimp for This Recipe?
Yes! Just make sure to fully thaw the shrimp before cooking. Thaw overnight in the fridge or quickly in a sealed bag submerged in cold water. Pat them dry to avoid excess moisture on the sheet pan.
Can I Make This Ahead of Time?
You can prep the vegetables and season the shrimp a few hours ahead and keep them covered in the fridge. Cook right before serving for the freshest texture and flavor.
How Should I Store Leftovers?
Store any leftover shrimp fajitas in an airtight container in the fridge for up to 2 days. Reheat gently in a pan or microwave to avoid overcooking the shrimp.
What Are Good Substitutions for Bell Peppers?
Try using zucchini or sliced mushrooms if you want to vary your veggies. Green bell peppers also work, though they have a slightly different flavor.
