Instructions

  1. Step 1: Preheat the oven to 425°F. Toss 3 medium peeled and chopped carrots, 2 medium peeled and chopped parsnips, and 1 medium red onion cut into wedges with 2 tbsp olive oil, 2 tsp chopped fresh thyme, 1/2 tsp salt, and 1/4 tsp black pepper. Spread evenly on a baking sheet and roast for 25 minutes until golden and tender.
  2. Step 2: While vegetables roast, mix 3 tbsp maple syrup and 2 tbsp Dijon mustard in a small bowl to create the maple-Dijon glaze.
  3. Step 3: Heat 2 tbsp olive oil in a large skillet over medium-high heat. Season 4 Atlantic cod fillets (6 oz each) with 1/2 tsp salt and 1/4 tsp black pepper. Place fillets skin-side down and cook for 4 minutes until the skin is crispy and golden.
  4. Step 4: Flip the cod fillets and brush the maple-Dijon glaze generously over the top. Cook for an additional 3 minutes until the fish is opaque and flakes easily with a fork.
  5. Step 5: Serve the maple-Dijon glazed cod alongside the roasted root vegetables, garnished with lemon wedges for squeezing.

How do I store leftover Pan-Seared Atlantic Cod with Maple-Dijon Glaze and Roasted Root Vegetables?
