Sheet Pan Shrimp Fajitas
These Sheet Pan Shrimp Fajitas are a quick, healthy weeknight dinner packed with juicy shrimp, colorful peppers, and bold fajita spices, all roasted together on one pan in under 30 minutes.
The Easiest Weeknight Dinner You Will Make All Year
If you have ever stood in the kitchen at 6pm wondering what is fast, healthy, and actually exciting to eat, these Sheet Pan Shrimp Fajitas are your answer. One pan, bold smoky spices, colorful roasted peppers and onions, and perfectly juicy shrimp, all ready in under 30 minutes with barely any cleanup. It is the kind of dinner that feels like a treat but fits right into a busy week.
Whether you are looking for keto shrimp fajitas, a lighter take on a restaurant favorite, or just a reliable sheet pan baked shrimp fajitas recipe you can come back to again and again, this one checks every box. It is naturally gluten-free with a simple swap, low in sodium compared to most fajita seasonings, and genuinely packed with flavor.
Why This Recipe Just Works
The magic here is all about high heat and a single layer. Roasting everything at 425 degrees F on a large sheet pan lets the vegetables caramelize at the edges while the shrimp cook through in just minutes. You get that smoky, slightly charred fajita flavor you love from a restaurant without standing over a screaming hot skillet.
A few things that make this recipe stand out:
- The spice blend is homemade. No packets, no mystery ingredients, and easy to adjust for low sodium shrimp fajitas by simply using less salt.
- The vegetables go in first. Peppers and onions need more time than shrimp. Staggering the cook time means nothing gets overdone.
- Pat the shrimp dry. This one small step makes a huge difference. Dry shrimp roast beautifully. Wet shrimp steam and turn rubbery.
- Fresh lime at the end. A squeeze of lime right out of the oven brightens every single flavor on that pan.
Chef's Tip: Do not crowd the pan. If your sheet pan is on the smaller side, use two pans rather than piling everything in. Crowding creates steam, and steam is the enemy of caramelization.
The Right Tools Make It Even Easier
For sheet pan cooking, the pan itself genuinely matters. A heavy rimmed 18x13 inch sheet pan distributes heat evenly and gives everything enough room to roast rather than steam. Using a good quality pan and lining it with foil also means cleanup takes about 30 seconds.
How To Make Shrimp Fajitas Keto or Low Carb
One of the best things about this recipe is how naturally it adapts to a low carb or keto lifestyle. The shrimp and roasted vegetable base is already lean, protein-rich, and low in sugar. To make it fully keto, simply skip the tortillas and serve the filling in one of these ways:
- Over cauliflower rice for a satisfying fajita bowl
- Inside large romaine or butter lettuce cups for a fresh, crunchy wrap
- On its own topped with avocado slices, a dollop of sour cream, and fresh salsa
You will not miss the tortillas one bit when the filling is this good. These zero point sheet pan shrimp fajitas are also a great fit for Weight Watchers plans depending on your serving setup.
Tips for the Best Results Every Time
Use large shrimp if you can. Smaller shrimp cook faster and can go from perfect to overdone very quickly in a hot oven. Large or jumbo shrimp give you a little more buffer and a meatier bite.
Slice your vegetables thin and uniform. About a quarter inch thick is ideal. Too thick and they will not soften enough in the time the shrimp need. Thin, even slices mean everything finishes cooking together.
Do not skip the lime. You can use it in the marinade, squeeze it over at the end, and serve extra wedges on the side. Lime is what ties all the smoky, savory spices together and makes the whole dish feel alive.
Quick Note on Sodium: The homemade spice blend in this recipe keeps sodium significantly lower than store-bought fajita packets. If you are specifically watching your intake for low sodium shrimp fajitas, start with half the salt listed and taste as you go. The spices carry plenty of flavor on their own.
What To Serve With Sheet Pan Shrimp Fajitas
This recipe is flexible and pairs well with so many sides and toppings:
- Warm flour or corn tortillas (or lettuce cups for low carb)
- Guacamole or sliced avocado
- Fresh pico de gallo or your favorite jarred salsa
- A dollop of Greek yogurt or sour cream
- Shredded Mexican cheese blend
- Cilantro lime rice or cauliflower rice on the side
For a full spread, a simple black bean salad or elote-style corn alongside makes this feel like a proper fajita night.

Sheet Pan Shrimp Fajitas
These Sheet Pan Shrimp Fajitas are a quick, healthy weeknight dinner packed with juicy shrimp, colorful peppers, and bold fajita spices, all roasted together on one pan in under 30 minutes.
Ingredients
- 1 1/2 lb large shrimp, peeled and deveined, tails on or off
- 2 red bell pepper, thinly sliced
- 1 yellow bell pepper, thinly sliced
- 1 green bell pepper, thinly sliced
- 1 yellow onion, thinly sliced into half-moons
- 3 tbsp olive oil, extra virgin
- 1 1/2 tsp chili powder
- 1 tsp cumin, ground
- 1/2 tsp smoked paprika
- 1/2 tsp garlic powder
- 1/4 tsp onion powder
- 1/2 tsp salt, or to taste
- 1/4 tsp black pepper, freshly ground
- 2 lime, 1 juiced for the marinade, 1 cut into wedges for serving
- 1/4 cup fresh cilantro, roughly chopped, for garnish
- 8 small flour or corn tortillas, warmed, for serving (omit for low-carb or keto)
Instruction
Preheat your oven to 425 degrees F (220 degrees C) and line a large rimmed sheet pan with foil or parchment paper for easy cleanup.
In a small bowl, combine the chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and black pepper. Stir until fully mixed.
Add the sliced bell peppers and onion to the sheet pan. Drizzle with 2 tablespoons of olive oil, sprinkle with half of the spice blend, and toss well to coat. Spread into an even single layer.
Roast the peppers and onions for 8 to 10 minutes, until they begin to soften and develop slight color at the edges.
While the vegetables roast, pat the shrimp completely dry with paper towels. This step is important for good browning. Place them in a bowl and toss with the remaining 1 tablespoon of olive oil, the remaining spice blend, and the juice of 1 lime.
Remove the pan from the oven. Push the vegetables to the sides and scatter the seasoned shrimp across the center of the pan in a single layer.
Return the pan to the oven and roast for 5 to 7 minutes, until the shrimp are pink, opaque, and just curled. Do not overcook.
Remove from the oven and squeeze extra lime juice over the top. Garnish with fresh cilantro.
Serve immediately in warm tortillas with your favorite toppings such as avocado, sour cream, salsa, or shredded cheese.

Notes
Storing and Reheating Leftovers
Leftovers keep well in an airtight container in the refrigerator for up to 3 days. Store the shrimp and vegetable mixture on its own, separate from any tortillas, to keep things from getting soggy.
To reheat, warm the filling in a skillet over medium heat for 2 to 3 minutes. The stovetop is far kinder to shrimp than the microwave, which tends to keep cooking them and can make them tough. A splash of lime juice while reheating brings everything back to life.
If you are meal prepping for the week, you can slice all the vegetables and mix the dry spice blend up to 2 days in advance. When dinnertime comes, everything goes on the pan and into the oven with almost zero effort.
