High-Protein Sheet Pan Salmon with Roasted Seasonal Vegetables
Tender salmon, caramelized seasonal vegetables, and a simple lemon-herb dressing — all on one pan. Ready in 20 minutes, packed with protein, and minimal cleanup.
This is the dinner you’ll come back to again and again. Fresh salmon fillets are paired with a colorful mix of seasonal vegetables — think broccoli, bell peppers, zucchini, and red onion — all tossed in a simple lemon-herb marinade and roasted to perfection on a single sheet pan. The salmon stays moist and flaky, the veggies get beautifully caramelized, and cleanup is a breeze. Serve with quinoa, rice, or crusty bread to soak up every last bit of flavor.

Step-by-Step Instructions (20 minutes)
The key to success? Get your vegetables in the oven first, then add the salmon. Everything finishes at the same time.
- 1Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper for easy cleanup.
- 2Prepare the vegetables. Wash and chop your seasonal vegetables into bite-sized pieces (about 2-inch chunks). Place them on the prepared sheet pan.Tip: Keep vegetables similar in size for even roasting.
- 3Season the vegetables. Drizzle with 2 tablespoons of olive oil, add minced garlic (2 cloves), salt, pepper, and a pinch of dried oregano or thyme. Toss to coat evenly. Spread in an even layer.
- 4Roast the vegetables first. Place the sheet pan in the oven and roast for 8 minutes while you prepare the salmon.
- 5Prepare the salmon. Pat salmon fillets dry with paper towels. In a small bowl, mix 1 tablespoon olive oil, lemon zest, salt, pepper, and chopped fresh herbs (parsley or dill). Brush or rub this mixture over the salmon.
- 6Add salmon to the pan. After 8 minutes, remove the pan from the oven. Push the vegetables to the sides and place the salmon fillets in the center. Return to the oven and roast for another 10-12 minutes, until salmon is flaky and opaque and vegetables are tender and caramelized.7Finish and serve. Squeeze fresh lemon juice over everything. Garnish with additional fresh herbs. Serve immediately with quinoa, rice, or a slice of crusty bread.Pro tip: For extra-crispy salmon skin, pat the fillets very dry before seasoning and place them skin-side down. Don’t flip them — the skin will become deliciously crackly. If your vegetables are crowding the pan, use two pans or roast in batches for maximum caramelization.
Storage & Meal-Prep Tips
Refrigerator: Store leftovers in an airtight container for up to 3 days. The salmon is delicious cold flaked over a salad or gently reheated in a skillet.
Reheating: To keep salmon moist, reheat in a 300°F (150°C) oven for 5-8 minutes, or gently in a covered skillet with a splash of water. Avoid the microwave if possible — it can dry out the fish.
Meal-prep strategy: Roast a double batch of vegetables at the beginning of the week. Cook fresh salmon each night (it only takes 12 minutes!) or prep the salmon portioned and ready to go.

Frequently Asked Questions
How do I know when the salmon is perfectly cooked?Salmon is done when it flakes easily with a fork and is opaque throughout. For precise results, use an instant-read thermometer: 125°F (52°C) for medium, 135°F (57°C) for well-done. The fish will continue cooking slightly after you remove it from the oven.Can I use frozen salmon?Yes, but you’ll need to thaw it completely first. Pat it very dry before seasoning — excess moisture will prevent browning. You may need to add 2-3 minutes to the cooking time. Never cook frozen salmon directly on a sheet pan with vegetables, as it will steam instead of roast.What if my vegetables are cooking faster than the salmon?Cut vegetables larger if they’re roasting quickly, or add them to the pan later. Dense vegetables like carrots, potatoes, and Brussels sprouts take longer — cut them smaller. Tender vegetables like zucchini and bell peppers cook faster — cut them larger or add them when you add the salmon.Can I make this recipe with other fish?Absolutely! Trout, arctic char, halibut, or thick cod fillets work beautifully. Adjust cooking time based on thickness: thinner fillets need less time, thicker cuts need a few extra minutes. White fish like cod will cook faster (8-10 minutes total).How do I get crispy vegetables without burning them?Don’t overcrowd the pan — use two pans if needed. Spread vegetables in a single layer with space between pieces. Use high heat (425°F/220°C) and avoid flipping them too often. Parchment paper helps, but a bare pan gives the best browning (just add a little more oil).What readers are saying (3 reviews)MMichelle R.April 28, 2025★★★★★This has become our go-to weeknight dinner.
