Fajitas are a favorite at our house because they’re flavorful, forgiving, and easy to customize. This version uses salmon baked right on a sheet pan alongside bell peppers and red onion so everything cooks together and the flavors meld beautifully. The lime‑garlic spice mixture brightens the salmon while cumin, chili powder and paprika add classic fajita warmth.

Sheet Pan Salmon Fajitas

These sheet pan salmon fajitas are perfect for busy nights because they require minimal prep and just one pan to wash. The method is simple: arrange salmon filets on a baking sheet, scatter sliced bell peppers and red onion around the fish, whisk a lime‑based dressing with spices, drizzle everything, and roast until cooked through. You can serve the finished fajitas piled into flour tortillas for a traditional handheld meal or over a bed of rice to make a grain bowl.

Here are a few quick tips to get the best results:

• Trim and slice the peppers and onions into similar sizes so they cook evenly.
• If you prefer a bit more char on the vegetables, place the pan under the broiler for 1–2 minutes at the end—watch closely to avoid burning.
• Use fresh lime juice for the brightest flavor; bottled lime juice will work in a pinch but won’t be as vibrant.
• Leftovers keep well refrigerated for up to 2 days—store sauce and toppings separately for best texture.

Why this recipe works

Baking salmon and vegetables together on a single sheet pan concentrates flavors and makes cleanup quick. The spice blend is simple but balanced—cumin and chili powder lend warmth, paprika adds color and a mild smoky note, garlic brings depth, and lime juice pulls everything together with acidity. Toppings like avocado, cilantro and a splash of hot sauce give contrasting textures and extra brightness.

Ingredients

• 2 salmon filets (about 6 oz each)
• 2 cups bell pepper, sliced
• 1 cup red onion, sliced
• 1 tbsp olive oil
• 2 tbsp fresh lime juice (about 1 lime)
• 2 cloves garlic, crushed
• 1/2 tsp cumin
• 1/2 tsp chili powder
• 1/2 tsp paprika
• 1/2 tsp sea salt

Serve with

• Cooked white rice (about 2 cups) or fajita‑size flour tortillas

Optional toppings

• 2 tbsp fresh cilantro, chopped
• 1 avocado, sliced
• 1 tomato, chopped
• Hot sauce, to taste

Instructions

1. Preheat the oven to 400°F (204°C).
2. Line a baking sheet with foil for easy cleanup and place the salmon filets in the center of the pan.
3. Arrange the sliced bell peppers and red onion around the salmon so everything fits in a single layer.
4. In a small bowl, whisk together the olive oil, lime juice, crushed garlic, cumin, chili powder, paprika and sea salt.
5. Drizzle the spice mixture evenly over the salmon and the vegetables.
6. Bake for 20 minutes, or until the salmon is cooked through and flakes easily with a fork. If you like more color on the vegetables, broil for 1–2 minutes at the end—watch carefully to prevent burning.
7. Serve immediately over rice or spoon the salmon and peppers into warmed tortillas. Add optional toppings like cilantro, avocado, tomatoes and a splash of hot sauce.

Notes

• If you plan to serve the salmon fajitas as a rice bowl, start cooking the rice before you prepare the sheet pan so everything comes together at the same time.
• Nutritional values provided below do not include rice, tortillas, or optional toppings.
• To scale the recipe, increase salmon and vegetables proportionally and adjust baking time slightly if the pan becomes crowded.
