Line a large baking sheet with aluminum foil. Place the salmon in the center of the foil, skin-side down. Rub the minced garlic evenly all over the fillet and season the salmon with salt and pepper. Spread the pesto all over the top. Set aside.
In a bowl, toss the tomatoes with olive oil and season with salt and pepper.
Arrange the tomatoes around the salmon filet.
Bake for 22 to 25 minutes, or until the salmon is flaky and the internal temperature of the salmon registers at 145˚F. Use an Instant Read Thermometer to check for doneness.
Remove from oven and let it rest for 4 minutes.
Cut the salmon into individual-sized filets.
Serve with the cooked tomatoes and a side of lemon wedges.
Notes
Salmon options: In this delicious recipe I used a whole salmon fillet, but if you have individual salmon fillets that you'd like to use up, that will also work. For individual sized fillets, you may want to start checking for doneness around the 16-minute mark.
Cooking Time: Salmon cooks fairly quickly, and in general, most fish are done in under 25 minutes. However, the timing will vary depending on the size and thickness of the fillet(s). To make sure that it's cooked through, always use an Instant Read Meat Thermometer.
Tomatoes and Veggies: Feel free to add any other veggies that you like or have on hand. Slices of zucchini, onions, strips of bell peppers, broccoli, and so on are all great options.
Basil Pesto: I recommend using about 3/4-cup pesto, but if you want to use more or less, that is up to you and totally OK to do.
