Sheet Pan Shrimp Fajitas
These Sheet Pan Shrimp Fajitas are a fast, healthy weeknight dinner loaded with juicy seasoned shrimp, colorful peppers, and bold fajita flavor, all roasted to perfection on a single pan in under 30 minutes.
The Easiest Weeknight Dinner You Will Make All Year
If your weeknights feel like a constant negotiation between time, energy, and actually wanting to eat something good, these Sheet Pan Shrimp Fajitas are about to become your new best friend. Everything roasts together on a single pan, the cleanup is minimal, and the flavor? Bold, smoky, citrusy, and genuinely satisfying. We are talking tender shrimp, caramelized peppers, and a well-balanced homemade spice blend that tastes like it came from your favorite Mexican restaurant.
This recipe checks every box. It is naturally low carb and easy to make keto-friendly by swapping tortillas for lettuce wraps or cauliflower rice. It is lower in sodium than takeout versions. And it is ready from fridge to table in about 25 minutes, which means it wins on busy Tuesday nights without question.
Why the Sheet Pan Method Is a Game Changer
Traditional fajitas are made in a screaming-hot cast iron skillet, which is delicious but requires attention, good ventilation, and some confidence at the stove. The sheet pan method flips that entirely. By roasting everything in a high-heat oven, you get beautiful caramelization on the vegetables and perfectly cooked shrimp without standing over the stove or timing multiple batches.
The key is sequencing. The peppers and onions go in first for a head start since they need more time to soften and develop those slightly charred, sweet edges. The shrimp follow for just 6 to 8 minutes at the end. Timing them separately on the same pan is the small trick that makes every component shine.
Chef's Tip: Always pat your shrimp completely dry before seasoning. Moisture on the surface steams the shrimp instead of roasting them, and you lose the slightly crisp, caramelized edges that make baked shrimp fajitas so satisfying.
The Spice Blend: Bold, Balanced, and Built From Scratch
Forget the seasoning packets. This homemade fajita spice blend uses pantry staples you almost certainly already have, and it lets you control exactly what goes into the dish. For anyone following a low sodium shrimp fajitas approach, the salt is easy to reduce or swap for a salt-free alternative without sacrificing any of the flavor depth.
Here is what makes the blend work:
- Smoked paprika adds a subtle depth that plain paprika simply cannot match
- Cumin brings that warm, earthy backbone classic to Tex-Mex cooking
- Chili powder provides color and mild heat without overwhelming the shrimp
- Garlic and onion powder round everything out and make the seasoning stick beautifully
- A pinch of cayenne is optional but highly recommended if you enjoy a little fire
Fresh minced garlic and a generous squeeze of lime juice go directly onto the shrimp for a bright, aromatic finish that ties the whole dish together.
Choosing the Right Shrimp and Tools
For sheet pan baked shrimp fajitas, large shrimp (26 to 30 per pound) work best. They are substantial enough to hold up to the heat without overcooking in the time it takes the rest of the filling to finish. Frozen shrimp are completely fine here: thaw them under cold running water and dry them very well.
Having a proper large rimmed sheet pan makes a real difference in this recipe. A pan that is too small crowds the ingredients, causing them to steam rather than roast. The right tools and quality ingredients are genuinely what separate good fajitas from great ones.
How To Make These Fajitas Keto and Zero Point Friendly
One of the best things about this recipe is how naturally it adapts to different dietary goals. The filling itself, shrimp, peppers, onion, and that homemade spice blend, contains no added sugar and is very low in carbohydrates.
To make keto shrimp fajitas or zero point sheet pan shrimp fajitas:
- Skip the tortillas entirely and serve the filling over cauliflower rice or shredded romaine
- Use corn tortillas instead of flour if you prefer a gluten-free option with fewer carbs
- Add avocado or guacamole for healthy fats that keep the meal filling
- Top with fresh pico de gallo instead of jarred salsa to keep sodium low
You are getting a genuinely complete, satisfying meal with excellent protein from the shrimp and plenty of fiber and vitamins from all those colorful peppers.
What To Serve With Sheet Pan Shrimp Fajitas
The filling is the star, but the right accompaniments make this a full spread. A few favorites:
- Warm flour or corn tortillas wrapped in a clean towel to keep them soft
- Fresh guacamole or sliced avocado
- Sour cream or plain Greek yogurt for a lighter, protein-rich swap
- Pico de gallo or a chunky fresh salsa
- Shredded cabbage or lettuce for crunch and freshness
- Extra lime wedges, always
For a low carb shrimp fajitas plate, pile the filling into butter lettuce cups with a dollop of guacamole and a sprinkle of cotija cheese. It is every bit as satisfying as the tortilla version.

Sheet Pan Shrimp Fajitas
These Sheet Pan Shrimp Fajitas are a fast, healthy weeknight dinner loaded with juicy seasoned shrimp, colorful peppers, and bold fajita flavor, all roasted to perfection on a single pan in under 30 minutes.
Ingredients
- 1 1/2 lb large shrimp, peeled and deveined, tails removed
- 1 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 ground cumin
- 1 tsp smoked paprika
- 3/4 tsp garlic powder
- 1/2 tsp onion powder
- 1/2 tsp kosher salt, adjust to taste
- 1/4 tsp black pepper, freshly ground
- 1/4 tsp cayenne pepper, optional, for extra heat
- 2 lime, 1 juiced for marinade, 1 cut into wedges for serving
- 3 garlic cloves, minced
- 1/4 cup fresh cilantro, roughly chopped, for garnish
- 8 small flour or corn tortillas, warmed, for serving; use corn tortillas to keep it gluten-free
Instruction
Preheat your oven to 425 degrees F (220 degrees C). Line a large rimmed sheet pan with foil or parchment paper and set aside.
In a small bowl, combine the chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, black pepper, and cayenne (if using). Stir until evenly mixed.
Place the sliced bell peppers and onion on the sheet pan. Drizzle with 2 tablespoons of olive oil, sprinkle with half the spice blend, and toss to coat. Spread everything into a single layer.
Roast the vegetables in the preheated oven for 8 minutes, until they begin to soften and caramelize at the edges.
While the vegetables roast, pat the shrimp completely dry with paper towels. In a bowl, toss the shrimp with the remaining 1 tablespoon of olive oil, the minced garlic, the juice of 1 lime, and the remaining spice blend until every shrimp is well coated.
Remove the sheet pan from the oven and push the vegetables to the edges. Arrange the shrimp in a single layer in the center of the pan.
Return the pan to the oven and roast for 6 to 8 minutes, until the shrimp are pink, opaque, and lightly curled. Be careful not to overcook.
Remove from the oven and immediately squeeze the remaining lime wedges over everything. Scatter with fresh cilantro.
Serve straight from the pan with warm tortillas and your favorite toppings such as avocado, sour cream, or pico de gallo.

Notes
Storing and Reheating Leftovers
Leftovers keep beautifully in the refrigerator for up to 3 days in an airtight container. Store the shrimp and vegetable filling separately from your tortillas to prevent sogginess.
To reheat, skip the microwave. A hot skillet over medium-high heat for 2 to 3 minutes brings everything back to life without turning the shrimp rubbery. A fresh squeeze of lime right before serving wakes the flavors back up.
For meal prep, slice the peppers and onions and mix the spice blend up to 2 days in advance. When dinner time comes, assembly and cooking take under 30 minutes. It is genuinely one of the most practical healthy sheet pan fish and shrimp fajita recipes to have in your regular rotation.
