Ingredients

Servings 4
  • 4 salmon fillets (6 oz each), skin on
  • 2 medium sweet potatoes, peeled and cut into 1-inch cubes
  • 2 small fennel bulbs, trimmed and sliced
  • 2 tablespoons olive oil, divided
  • Salt and freshly ground black pepper, to taste
  • 1/4 cup Dijon mustard
  • 3 tablespoons honey
  • 1 tablespoon apple cider vinegar
  • 1 teaspoon smoked paprika
  • 1 teaspoon dried thyme
  • 1 lemon, sliced (optional, for garnish)
  • Fresh parsley, chopped (optional, for garnish)

Instructions

  1. Preheat oven to 425°F (220°C). Line a large rimmed baking sheet with parchment paper or a silicone baking mat.
  2. In a large bowl, toss the sweet potatoes and fennel with 1 tablespoon olive oil, salt, black pepper, smoked paprika, and dried thyme until evenly coated.
  3. Spread the vegetables in a single layer on the prepared baking sheet. Roast for 15 minutes, stirring once halfway through, until they begin to soften.
  4. Meanwhile, whisk together Dijon mustard, honey, apple cider vinegar, and remaining 1 tablespoon olive oil in a small bowl until smooth.
  5. Remove the baking sheet from the oven and push the roasted vegetables toward the edges, creating space in the center for the salmon fillets.
  6. Place the salmon fillets skin-side down in the center of the baking sheet. Generously brush each fillet with the honey-mustard glaze, reserving any extra for serving.
  7. Return the baking sheet to the oven and roast for an additional 10-12 minutes, or until the salmon is cooked through and flakes easily with a fork, and the vegetables are tender.
  8. Remove from oven and let rest for 2 minutes. Garnish with lemon slices and chopped parsley if desired.
  9. Serve warm, drizzling any remaining glaze over the salmon and vegetables.

Pan Or Pot Required

For this vibrant and healthy Mediterranean-inspired sheet pan dinner, a large rimmed baking sheet (sheet pan) is the essential cookware. It allows even roasting of salmon fillets, sweet potatoes, and fennel all together with minimal cleanup.

This setup perfectly matches our Sheet Pan Dinners category and tags like easy, quick, healthy, and onepan. Cooking everything in one pan saves time and effort for busy weeknight meal prep.

Ensure your baking sheet is large enough to arrange vegetables and salmon in a single layer without overcrowding. This promotes caramelization and prevents steaming, resulting in tender, flavorful ingredients.

Lining the pan with parchment paper or a silicone baking mat helps avoid sticking and simplifies cleanup.

No other pots or pans are needed, making this meal prep efficient while delivering delicious textures and flavors.

Cookware Size Guidance

For 4 servings of this Mediterranean sheet pan dinner, use a large rimmed baking sheet around 13 x 18 inches (half-sheet size). This size provides optimal space for roasting cubed sweet potatoes and sliced fennel alongside salmon fillets without overcrowding.

Smaller pans risk overcrowding ingredients, which can cause steaming instead of roasting, negatively impacting texture and flavor. The rim helps contain juices and glaze, reducing oven mess.

If a half-sheet pan is unavailable, use a similar-sized rimmed baking dish, but avoid deep pans that restrict airflow needed for even roasting.

This pan size supports quick, healthy, and family-friendly meal prep with consistent, delicious results.

Cookware Swap Guidance

This easy and flavorful sheet pan meal is designed for simplicity with a large baking sheet or rimmed sheet pan to roast salmon and vegetables together evenly. If you don’t have a sheet pan, consider these alternatives compatible with the recipe’s easy, onepan, family-friendly, and healthy style:

  • Roasting Pan with Rack: Separates salmon from vegetables while maintaining one-pan convenience; line with foil or parchment for easier cleanup.
  • Oven-Safe Casserole Dish: Large dishes can be used but keep ingredients in a single layer to encourage caramelization.
  • Cast Iron Skillet: Great for smaller portions or if you prefer searing; adjust ingredient amounts to avoid crowding and ensure even cooking.
  • Grill Pan or Grill Basket: Provides a grilled flavor indoors or on outdoor grills; requires close monitoring to ensure even cooking.

Note that pans with smaller surface area may increase cooking time or change texture, so watch carefully. The hallmark of this recipe remains simple cleanup and melded flavors from roasting on a flat sheet pan.

Leftovers Quality

This Sheet Pan Honey-Mustard Glazed Salmon with Roasted Fennel and Sweet Potatoes makes delicious and convenient leftovers. Store salmon and vegetables separately in airtight containers in the refrigerator for up to 2 days to preserve freshness and texture, especially important for seafood.

Reheat gently in a 275°F (135°C) oven for about 10 minutes until warmed through to maintain salmon’s moist, flaky texture and keep vegetables from drying out. Alternatively, microwave on medium power in short intervals, stirring vegetables occasionally to avoid overcooking.

Freezing cooked salmon and vegetables is not recommended due to texture changes, but you can freeze leftover honey-mustard glaze in a small container for up to 1 month to brighten future meals.

These storage and reheating tips help keep leftovers just as flavorful, healthy, and satisfying as the original meal.
