Heat the oven to 425°F (220°C). In a small bowl, mix the butter, olive oil, basil, garlic powder, paprika, salt, and pepper.
Place the salmon skin-side down on a foil-lined baking sheet. Spread the butter mixture evenly over the top.
Bake for 12–15 minutes, until the salmon flakes easily with a fork. Cover to keep warm.Note: For accuracy, check with an instant-read thermometer. The FDA recommends 145°F, but I prefer 135°F. Cook’s Illustrated suggests 120°F for wild salmon and 125°F for farmed.
Make the Salsa
In a medium bowl, combine cucumbers, red onions, red peppers, garlic, jalapeños, and cilantro.
In a small bowl, whisk lime juice, olive oil, salt, and pepper, then pour over the vegetables and toss.
Assemble
Add rice to a serving bowl. Top with salmon and spoon the cucumber salsa over the top.
Notes
Use a Meat Thermometer: An inexpensive thermometer helps ensure salmon (and other proteins) are cooked to the right temperature without overcooking.
White Substance on Salmon: Don’t worry if you see a white layer on the fish, it’s a harmless protein called albumin that appears when salmon is heated.
Avoid Waste: Check the “Ways To Use Leftover Ingredients” section below for more recipes that use the same ingredients.
Make Ahead: The cucumber salsa can be prepared in advance and stored in the refrigerator.
