Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Toss sweet potato cubes with 1 tbsp sesame oil, 1/4 tsp salt, and 1/4 tsp pepper; spread on a baking sheet and roast for 20 minutes until tender and slightly caramelized.
  2. Step 2: In a small bowl, whisk soy sauce, rice vinegar, honey, garlic, and remaining 1 tbsp sesame oil until combined. Set aside.
  3. Step 3: Heat a skillet over medium-high. Pat halibut dry and season with 1/4 tsp salt. Sear for 3-4 minutes per side until golden. Pour glaze over fish and cook for 1 more minute, basting occasionally, until sauce thickens and coats fish.

Frequently asked questions

How long does Sesame-Glazed Halibut with Roasted Sweet Potatoes take to make?

Total time is about 35 minutes (10 min prep + 25 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Sesame-Glazed Halibut with Roasted Sweet Potatoes?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish). Store any fresh salsa or citrus-based garnish in a separate container — it keeps for up to 2 days. Freeze cooked fish (without fresh garnishes) for up to 3 months; thaw overnight in the fridge and reheat gently at 275°F until just warmed through to preserve texture.

Can I substitute ingredients in Sesame-Glazed Halibut with Roasted Sweet Potatoes?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.
