Cod Sweet Potato with Garlic Herb Sauce
Tender, flaky white fish pairs naturally with earthy, caramelized roasted sweet potatoes, but the real key to tying this plate together is the pungent, herby garlic oil spooned over the top just before serving. Because the components finish around the same time, it makes for a straightforward, satisfying seafood dinner.
Why this one works
- Golden pan-seared cod stays moist and flaky while developing light browning.
- Roasted sweet potato cubes offer natural sweetness and tender texture.
- Whisked fresh garlic and parsley oil adds bright, savory contrast.
- Straightforward workflow with minimal active prep required.
What you’ll need
- 2 fillets (340g) cod Look for evenly thick fillets so they cook through consistently without drying out at the edges.
- 2 large (400g) sweet potatoes Cut into uniform, bite-sized cubes so every piece roasts evenly in the oven.
- 3 tablespoons (45g) olive oil Divided between roasting the potatoes, searing the fish, and mixing the sauce.
- 4 cloves (20g) minced garlic Mince finely so the raw garlic distributes evenly throughout the finishing sauce.
- 1 tablespoon (5g) chopped fresh parsley Adds clean herbal color and brightness to balance the richness of the oil.
- 1/2 teaspoon (3g) fine salt
- 1/4 teaspoon (1g) ground black pepper

A few things worth knowing
- Pat the cod fillets dry with paper towels before seasoning to help achieve a cleaner sear in the skillet.
- Spread the sweet potato cubes in a single layer on the baking sheet to ensure they roast rather than steam.
- Let the skillet get properly hot before adding the fish so it browns nicely without sticking.
Ways to make it your own
- Garnish with an extra pinch of chopped flat-leaf parsley or cracked black pepper.
- Serve with fresh lemon wedges alongside to squeeze over the fish at the table.
Serving suggestions
Plated together, the fish and sweet potatoes form a balanced main dish. A simple side of steamed greens, sauteed spinach, or a light cucumber and leafy green salad complements the rich garlic sauce nicely.
Storage & reheating
Store leftover cod and sweet potatoes in airtight containers in the refrigerator. Reheat gently on the stovetop or in a moderate oven until warmed through, taking care not to overheat the fish to preserve its flaky texture.
