This is a great combination for a quick, flavorful dinner! Chimichurri sauce is like a burst of summer color and flavor.
Preheat oven to 425°F. Line a rimmed baking sheet with foil or parchment paper and spray with cooking spray.
To prepare salmon: Place salmon skin-side down on the prepared baking sheet. Rub with oil and sprinkle with salt and pepper. Roast until it flakes easily with a fork in the thickest part, 8 to 10 minutes per inch of thickness.
To serve, slide a thin spatula under each piece of fish, separating it from the skin, and place on a plate. Serve with about 2 tablespoons sauce each.
Serve with mashed potatoes, as shown here, or with roasted root vegetables!
