Ingredients

Scale

Salmon and Marinade

  • 4 salmon fillets (5 oz each)
  • 2 tablespoons fajita seasoning
  • 1/4 teaspoon sea salt
  • 1/4 teaspoon cayenne pepper
  • 2 tablespoons fresh lime juice
  • 2 tablespoons fresh orange juice
  • 2 tablespoons coconut aminos (or liquid aminos or low sodium soy sauce)
  • 2 fresh garlic cloves, minced
  • 2 tablespoons olive oil (or avocado or coconut oil)

Vegetables

  • 3 bell peppers, sliced (any color combination)
  • 1 large white onion, sliced
  • 1 tablespoon avocado oil (or olive oil)

Garnish and Serving

  • 2 tablespoons fresh chopped cilantro or parsley
  • Fresh lime wedges, for serving
  • Cooked browned rice, to serve alongside (optional)

Instructions

  1. Prepare Seasoning Mix: Whisk together the fajita seasoning, 1/4 teaspoon salt, and 1/4 teaspoon cayenne pepper in a small bowl and set aside.
  2. Make Marinade: In a shallow large bowl or dish, combine the lime juice, orange juice, coconut aminos, minced garlic, olive oil, and half of the fajita seasoning mixture. Whisk well to create the marinade.
  3. Marinate Salmon: Remove 1 tablespoon of the marinade and set it aside for the vegetables. Add salmon fillets to the remaining marinade, coating well. Let the salmon marinate at room temperature for 30 minutes to absorb the flavors.
  4. Preheat Oven: Preheat your oven to 400°F (200°C). Line a baking sheet with foil or parchment paper and lightly spray with cooking spray to prevent sticking.
  5. Prepare Vegetables: Spread the sliced onions and bell peppers on the prepared baking sheet. Sprinkle with 1 tablespoon of fajita seasoning and 1/4 teaspoon sea salt. Drizzle with 1 tablespoon avocado oil and the reserved marinade. Toss everything together until the vegetables are evenly coated and then spread them out evenly on the sheet.
  6. Season and Add Salmon: Remove the salmon from the marinade and rub the remaining fajita seasoning all over the fillets. Place the salmon fillets on the baking sheet alongside the vegetables.
  7. Bake: Place the baking sheet in the preheated oven and bake for 12 to 16 minutes, or until the salmon is fully cooked through and flakes easily with a fork.
  8. Garnish and Serve: Once baked, sprinkle the salmon and vegetables with fresh chopped cilantro or parsley. Serve immediately with cooked browned rice and fresh lime wedges on the side for an extra burst of flavor.

Notes

  • Marinate salmon at room temperature for better absorption of flavors and even cooking.
  • Use any combination of bell peppers for a colorful presentation and variety of flavors.
  • If you prefer less heat, reduce or omit the cayenne pepper in the seasoning.
  • Line the baking sheet with foil or parchment paper to make cleanup easier.
  • Serve with warm tortillas if you want to make traditional fajitas.
  • Cooked browned rice pairs well with this dish for a complete meal, but you can substitute with quinoa or cauliflower rice for a low-carb option.
