Sheet Pan Shrimp Fajitas

The Weeknight Dinner That Does All the Work for You

There are weeknights when the last thing you want to do is stand over a hot stove juggling multiple pans. That is exactly why these Sheet Pan Shrimp Fajitas have earned a permanent spot in my dinner rotation. One pan, bold seasoning, juicy shrimp, and sweet charred peppers, all ready in about 30 minutes flat. It is the kind of meal that feels festive and special without asking anything complicated of you.

Whether you are keeping things keto, looking for a low carb shrimp fajitas option, or just need a fast and satisfying family dinner, this recipe delivers every single time. And because everything roasts together at high heat, you get that gorgeous caramelization on the vegetables that you just cannot achieve from a quick stovetop saute.

Why the Oven Is Your Best Friend for Fajitas

Most fajita recipes call for a screaming hot cast iron skillet or a grill. Both are great, but sheet pan baked shrimp fajitas have a few advantages that make them ideal for busy home cooks.

• Hands-off cooking. You prep, toss, and let the oven do the heavy lifting.
• Even cooking. High heat from all sides means the peppers soften perfectly without going mushy.
• No babysitting. Unlike stovetop fajitas, there is no constant stirring or monitoring.
• Easy cleanup. Foil-lined pan means you are basically done before you start.

The key is getting your oven up to 425 degrees F so things roast rather than steam. That high heat is what gives you those slightly charred, caramelized edges on the peppers and onions that make fajitas so irresistible.

Chef's Tip: Always pat your shrimp completely dry before seasoning. Moisture on the surface prevents browning and causes the shrimp to steam in the oven instead of roasting. A few seconds with a paper towel makes a real difference.

Building the Perfect Fajita Seasoning

You could reach for a store-bought packet, but a homemade fajita spice blend takes about 60 seconds to mix and tastes dramatically better. Here is what goes into ours:

• Chili powder for warmth and depth
• Smoked paprika for that subtle, almost smoky char flavor
• Cumin because it is simply non-negotiable in any fajita recipe
• Garlic powder and onion powder for savory backbone
• Cayenne if you like a little kick
• Fresh lime juice to brighten everything at the end

This blend is also what makes these work beautifully as low sodium shrimp fajitas compared to most restaurant versions. You are in full control of the salt, and a little goes a long way when the other spices are this fragrant.

Using good quality spices and the right equipment makes a noticeable difference in how this recipe turns out. A sturdy large rimmed baking sheet ensures even heat distribution and prevents drips, while a quality citrus juicer gets every drop of lime juice without seeds or effort.

Tips for Getting This Recipe Just Right

If you want to know how long to cook shrimp fajitas in the oven, the short answer is: not long. Shrimp are one of the fastest proteins you can cook, and at 425 degrees F they need only 8 to 10 minutes. The trick with this sheet pan method is to roast your vegetables first, then add the shrimp partway through so nothing gets overcooked.

Here is the simple two-stage approach:

1. Roast the peppers and onions first for about 10 minutes, until they start to soften and pick up a little color.
2. Add the shrimp to the pan and return it to the oven for 8 to 10 more minutes.

This timing is what separates a great result from rubbery, overcooked shrimp sitting on top of still-crunchy vegetables. Trust the process.

Watch for the curl. Properly cooked shrimp curl into a loose C shape. If they tighten into a full O, they have gone a minute too long. Pull the pan the moment they turn fully pink and opaque.

Making It Low Carb and Keto

One of the things people love most about this recipe is how naturally it adapts to different eating styles. The shrimp and vegetable filling itself is already keto shrimp fajitas territory, coming in at around 14 grams of carbs per serving before any tortillas. To make shrimp fajitas keto, simply swap the tortillas for:

• Butter lettuce cups for a fresh, crunchy wrap
• Cauliflower rice served as a bowl
• Shredded cabbage as a base for a fajita slaw situation
• Low carb tortillas if you still want the wrap experience

For anyone tracking points, these are also essentially zero point sheet pan shrimp fajitas on most plans when you skip the tortillas and use a light cooking spray instead of olive oil. The filling alone is protein-packed, fiber-rich, and deeply satisfying.

Scale

1x2x3x

• 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 large 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
• 1/2 tsp garlic powder
• 1/2 tsp onion powder
• 3/4 tsp kosher salt, adjust to taste
• 1/4 tsp black pepper, freshly ground
• 1/4 tsp cayenne pepper, optional, for extra heat
• 2 fresh lime, 1 juiced for marinade, 1 cut into wedges for serving
• 8 small flour or corn tortillas, warmed, for serving; use corn tortillas for gluten-free
• 1/4 cup fresh cilantro, roughly chopped, for garnish

Instruction

1

Preheat your oven to 425 degrees F (220 degrees C). Line a large rimmed baking sheet with foil and lightly coat with cooking spray or a drizzle of oil.

2

In a small bowl, combine the chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, black pepper, and cayenne (if using). Stir until well mixed.

3

Spread the sliced bell peppers and onions onto the prepared baking sheet. Drizzle with 2 tablespoons of the olive oil and sprinkle with half the seasoning blend. Toss everything directly on the pan to coat evenly.

4

Roast the peppers and onions for 10 minutes, until they begin to soften and get a little color on the edges.

5

While the vegetables roast, pat the shrimp dry with paper towels and place them in a bowl. Add the remaining 1 tablespoon of olive oil, the rest of the seasoning blend, and the juice of 1 lime. Toss well to coat every shrimp.

6

Remove the pan from the oven and push the vegetables to the sides to create space in the center. Spread the seasoned shrimp out in a single layer on the pan.

7

Return the pan to the oven and roast for 8 to 10 minutes, until the shrimp are pink, opaque, and just cooked through. Do not overcook.

8

Remove from the oven and squeeze a little extra lime juice over everything. Serve immediately in warm tortillas topped with fresh cilantro, and any desired toppings.

Equipment

• Large rimmed baking sheet (18x13 inch)
• Aluminum foil
• Small mixing bowl
• Large mixing bowl
• Paper towels
• Sharp chef's knife
• Cutting board
• Citrus juicer

Notes

For the best results, do not skip patting the shrimp dry before seasoning. Excess moisture is the enemy of a good roast and can cause the shrimp to steam rather than caramelize. Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over medium heat or in the oven at 300 degrees F. To keep this recipe keto or low carb, skip the tortillas and serve over cauliflower rice or a bed of shredded cabbage with your favorite toppings.

Serving Suggestions and Topping Ideas

Once your fajitas come out of the oven, the fun part begins. Load up your warm tortillas with the shrimp and pepper mixture, then pile on any combination of these toppings:

• Fresh cilantro and lime wedges (non-negotiable in my book)
• Sliced avocado or a scoop of guacamole
• A dollop of Greek yogurt or sour cream
• Pico de gallo or your favorite salsa
• Crumbled cotija cheese for a salty, creamy finish
• Pickled jalapeños for extra heat

Serve these alongside a simple green salad, Mexican street corn, or a pot of cilantro lime rice for a complete dinner spread. They are also incredible the next day stuffed into a burrito or tossed into scrambled eggs for a next-level fajita breakfast hash.

However you serve them, these sheet pan shrimp fajitas are the kind of recipe you will find yourself coming back to again and again, weeknight after weeknight, because they are just that good.
