Combine the olive oil, garlic, lime juice, salt, cayenne pepper, and half of the cilantro in a small bowl.(I used a lot more cilantro but will post as written)Stir to mix well.
Marinate the salmon with the mixture while he oven is preheating.
As soon as the oven is preheated, transfer the salmon to a baking sheet lined with aluminum foil or parchment paper, and bake until it’s cooked through, about 15 minutes.I didn’t use any foil or parchment paper and found it baked just fine in my pan without.
Remove from the oven, top with the remaining chopped cilantro and garnish with the lime.Serve immediately.
