Ingredients

4 salmon fillets (6 ounces each), skin-on or skinless
2 tablespoons olive oil
2 tablespoons fresh lemon juice
1 teaspoon lemon zest
2 cloves garlic, minced
1 teaspoon dried thyme
1 teaspoon dried rosemary
1 teaspoon dried parsley
Salt and freshly ground black pepper, to taste
1 small butternut squash, peeled and cubed
2 cups brussels sprouts, trimmed and halved
2 medium carrots, peeled and sliced into thin sticks
1 red bell pepper, sliced
1 small red onion, sliced
1 tablespoon balsamic vinegar
1 tablespoon honey or maple syrup (optional for sweetness)

Directions

1. Preheat the oven and prepare your baking sheet.
Begin by preheating your oven to 400°F (200°C). This temperature ensures that both the vegetables and salmon roast evenly, developing a rich, caramelized flavor while keeping the salmon tender and juicy. While the oven heats, line a large baking sheet with parchment paper to prevent sticking and make cleanup easy. If you prefer, you can lightly grease the baking sheet with a bit of olive oil. Using a sheet pan of sufficient size is important, as overcrowding can cause the vegetables to steam rather than roast, which would affect their texture and flavor.

2. Prepare the vegetables.
Next, focus on the seasonal vegetables. In a large mixing bowl, combine cubed butternut squash, halved brussels sprouts, sliced carrots, sliced red bell pepper, and thinly sliced red onion. Each vegetable brings a unique texture and flavor: the squash adds natural sweetness, brussels sprouts contribute a savory bite, carrots offer earthy tones, bell peppers bring vibrant color and mild sweetness, and red onion adds subtle sharpness. Drizzle the vegetables with one tablespoon of olive oil, followed by a tablespoon of balsamic vinegar, which enhances the natural sugars and adds a gentle tang. For a touch of autumnal sweetness, drizzle with honey or maple syrup if desired. Sprinkle generously with salt and freshly ground black pepper, then toss everything thoroughly to ensure each piece is evenly coated. This step is crucial for achieving consistent roasting and flavor throughout.

3. Roast the vegetables.
Once the vegetables are coated, spread them evenly on one side of the prepared baking sheet in a single layer. Make sure the vegetables have some space between them so they roast properly and develop a golden-brown exterior. Place the sheet in the preheated oven and roast for about 20 to 25 minutes. Halfway through, use a spatula to stir or flip the vegetables. This ensures even cooking and allows all surfaces to caramelize slightly, enhancing their natural sweetness and flavor. You’ll notice that the edges start to turn a rich golden-brown, and the vegetables become tender but not mushy, perfectly balancing texture and flavor.

4. Prepare the salmon fillets.
While the vegetables roast, turn your attention to the salmon. In a small bowl, mix one tablespoon of olive oil, two tablespoons of fresh lemon juice, one teaspoon of lemon zest, minced garlic, dried thyme, rosemary, parsley, and a pinch of salt and freshly ground black pepper. This herb and citrus mixture not only infuses the salmon with flavor but also helps keep it moist during cooking. Pat the salmon fillets dry with a paper towel, then gently rub the mixture evenly over each fillet, making sure every side is coated. If you’re using skin-on salmon, rub the seasoning on the flesh side, as the skin will protect the fish during roasting.

5. Add salmon to the oven.
After the vegetables have roasted for about 20 minutes, create space on the empty side of the baking sheet and place the salmon fillets there, skin-side down if applicable. Return the sheet pan to the oven and roast for an additional 12 to 15 minutes. The salmon is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C). During this time, the salmon absorbs the roasted aromas from the vegetables while retaining its moist and tender texture. The combination of citrus, herbs, and natural salmon oils creates a delicate, savory-sweet flavor profile that pairs beautifully with the roasted vegetables.

6. Serve immediately.
Once cooked, remove the baking sheet from the oven and carefully transfer the salmon and vegetables to a serving platter. Arrange the salmon fillets alongside the roasted vegetables for an appealing presentation. For a finishing touch, garnish with fresh lemon slices or additional fresh herbs, such as parsley or thyme. Serving immediately ensures that the salmon remains moist and the vegetables retain their perfect texture. This vibrant, colorful dish is perfect for a cozy family dinner, a weeknight meal, or entertaining guests, offering both nutritional benefits and seasonal flavors in every bite.

Frequently Asked Questions

Can I use frozen salmon?
Yes, you can use frozen salmon for this recipe, but it’s important to handle it properly to ensure the best results. First, fully thaw the salmon in the refrigerator overnight or under cold running water if you’re short on time. Once thawed, pat the fillets dry with paper towels to remove any excess moisture. This step is crucial because moisture on the surface can prevent the herb and lemon mixture from sticking properly and can cause the salmon to steam instead of roast. After drying, season and roast the salmon as directed. Using thawed salmon ensures even cooking, a flaky texture, and a flavorful finish.

Can I use other vegetables?
Absolutely! One of the great things about this sheet pan recipe is its flexibility. While butternut squash, brussels sprouts, carrots, bell peppers, and red onion are suggested, you can swap in other seasonal or favorite vegetables depending on availability and personal preference. Sweet potatoes, parsnips, cauliflower, broccoli, or even zucchini work beautifully. Just keep in mind that different vegetables may have slightly different cooking times. Denser vegetables like sweet potatoes and parsnips may need an extra 5–10 minutes to roast fully, while softer vegetables like zucchini may cook faster. Mixing textures and colors keeps the dish visually appealing and flavorful.

How do I know when salmon is done?
Salmon is perfectly cooked when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C). The flesh should be opaque, tender, and moist, not dry or rubbery. Overcooking can cause the salmon to lose its natural juices and become tough. To test for doneness, gently press the fillet with a fork at its thickest part—if it separates easily into flakes, it’s ready. Using a meat thermometer is the most accurate way to ensure the salmon is cooked safely while maintaining its delicate texture.

Can I prepare this ahead of time?
Yes, this recipe can be prepped in advance to make mealtime easier. You can chop the vegetables and store them in an airtight container in the refrigerator, and you can also prepare the salmon with the herb and lemon rub ahead of time. Keep the salmon separate from the vegetables until ready to roast. When it’s time to cook, simply spread the vegetables on the baking sheet, roast them partially, then add the salmon to finish cooking. This method saves time while keeping the flavors fresh and the textures perfect.
