Ingredients You’ll Need

The ingredient list for Pan-Seared Cod with Wasabi Sweet Potato Mash and Miso Glaze is short, sweet, and supremely purposeful. Every component brings something special to your plate, whether it’s the fluffy sweet potatoes, punchy wasabi, or the irresistible miso glaze. Here’s what you’ll need, plus a few pro tips for each.

• Sweet potatoes (2, medium, peeled and cubed): These lend the mash its gorgeous color and natural, earthy sweetness.
• Wasabi paste (2 teaspoons): Wasabi adds bold heat and authentic Japanese flavor; start with less, then add more if you like it spicy!
• White miso paste (2 tablespoons): This forms the soul of the miso glaze, packing umami and depth.
• Brown sugar (1 tablespoon): A little sweetener balances the salty, fermented miso.
• Sake (2 tablespoons): This imparts a gentle, aromatic boost to the glaze; dry white wine can be swapped if needed.
• Cod fillets (2): Choose fillets that are firm, bright, and boneless for flawless searing.
• Nori seaweed (1 sheet, finely shredded): Nori gives a delicate sea essence—use kitchen scissors to cut it into thin shreds for the perfect finishing touch.
• Black sesame seeds (1 tablespoon): These add a lovely crunch and contrast—toast them lightly for extra flavor.
• Fennel bulb (1, for pickling): Thinly sliced fennel brings refreshing crunch and a subtle aniseed note.
• Rice vinegar (1/2 cup, for pickling): Essential for quick pickles, offering tang that lifts the entire dish.
• Beetroot juice (1/2 cup, for pickling): Not just for color; it lends earthiness and a gentle sweetness to your pickled fennel.
• Olive oil (2 tablespoons): One for roasting the sweet potatoes, the other for pan-searing your cod.
• Salt and pepper (to taste): The unsung heroes—season generously and taste as you go to balance flavors perfectly.

How to Make Pan-Seared Cod with Wasabi Sweet Potato Mash and Miso Glaze

Step 1: Roast the Sweet Potatoes

Preheat your oven to 400 F (200 C). Toss your peeled and cubed sweet potatoes in a tablespoon of olive oil and a generous pinch of salt. Spread them out on a baking tray so they’ll roast evenly, developing caramelized edges and a creamy interior. Roast them for 20 to 25 minutes until fork-tender, shaking the tray halfway to avoid sticking.

Step 2: Whip Up the Miso Glaze

While your sweet potatoes roast, combine the white miso paste, brown sugar, and sake in a small saucepan over medium heat. Whisk everything together and let it slowly simmer. After just a few minutes, it transforms into a sticky, glossy glaze that’s bursting with umami and just a hint of sweetness. Set it aside—you’ll use it to brush the fish later!

Step 3: Pickle the Fennel

For a crunchy, tangy side, thinly slice one fennel bulb. In a small pot, bring the rice vinegar and beetroot juice to a boil. Once bubbling, toss in the fennel, stir to coat, then immediately remove from the heat. Let it soak and turn pink—it’s ready to serve when the rest of your Pan-Seared Cod with Wasabi Sweet Potato Mash and Miso Glaze is done.

Step 4: Mash and Wasabi It Up

Take your roasted sweet potatoes and mash them while still hot, folding in the wasabi paste to taste (start slow unless you’re a heat enthusiast). The wasabi’s boldness marries with the sweet potatoes’ creaminess, creating an exciting mash you’ll want to eat with everything. Keep it warm, covered, until plating time.

Step 5: Sear and Glaze the Cod

Season your cod fillets with salt and pepper. Heat the remaining tablespoon of olive oil in a skillet over medium-high heat. When the pan is shimmering hot, add the fillets and sear for 3 to 4 minutes per side—don’t move them too much to get that golden crust. In the final minute, brush the miso glaze generously over the top of each fillet, letting it caramelize and infuse the fish.

Step 6: Assemble and Garnish

Spoon a hearty scoop of wasabi sweet potato mash onto each plate. Place the glistening miso-glazed cod fillet on top. Drizzle with any leftover glaze, then sprinkle over the shredded nori and black sesame seeds for dramatic flair. Add the vibrant pickled fennel on the side for a pop of color and zingy crunch. Your Pan-Seared Cod with Wasabi Sweet Potato Mash and Miso Glaze is now ready to wow!

Garnishes

The finishing touches make this dish feel restaurant-worthy. A shower of finely shredded nori gives oceanic depth, while toasted black sesame seeds bring gorgeous contrast and nutty flavor. For an extra sparkle, a bit of microgreen or extra wasabi paste dotted on top sets each plate off beautifully. The pickled fennel not only adds a crisp crunch but its beetroot-stained hue looks stunning next to the golden fish and orange mash.

Side Dishes

You hardly need anything else, but if you’re feeling fancy or feeding a crowd, a crisp green salad with a zesty yuzu or ponzu dressing is perfect. Steamed jasmine rice or a bowl of miso soup makes a comforting accompaniment to the Pan-Seared Cod with Wasabi Sweet Potato Mash and Miso Glaze, while a chilled sake or citrusy white wine turns dinner into a celebration.

Creative Ways to Present

For an elegant dinner party, try serving the cod fillets over a bed of mash in small, wide bowls with the pickled fennel artfully fanned to the side. For a more casual meal, build a vibrant “bowl” by layering all the components and letting everyone help themselves. Or go tapas-style: plate miniature bites on Asian soup spoons for an impressive appetizer version that will tantalize your guests. However you present it, Pan-Seared Cod with Wasabi Sweet Potato Mash and Miso Glaze brings the wow every time.

Make Ahead and Storage

Storing Leftovers

If you find yourself with extra Pan-Seared Cod with Wasabi Sweet Potato Mash and Miso Glaze, lucky you! Store each component separately for best results. The sweet potato mash and miso-glazed cod keep well in airtight containers in the refrigerator for up to two days, while any leftover pickled fennel will stay crisp and flavorful for up to a week.

Freezing

While the sweet potato mash can be frozen (cool it thoroughly, then pack into airtight containers), the cod is best enjoyed fresh for peak texture. If you must freeze the fish, be aware the glaze may look a little different when thawed, but flavor-wise you’re still golden. The pickled fennel is not ideal for freezing, as it can lose the crunch you want.

Reheating

Gently reheat the sweet potato mash in the microwave or on the stove, adding a splash of water or milk to restore its creaminess. For the cod, use a very low oven (275 F) and cover loosely with foil to avoid drying it out—just 8 to 10 minutes should do it. The pickled fennel is best enjoyed cold or at room temperature, ready to perk up your leftovers straight from the fridge.

FAQs

Can I swap the cod for another fish?

Absolutely! Halibut, sea bass, or even salmon work beautifully with this recipe—just adjust cooking times depending on thickness. The miso glaze and wasabi mash are universally delicious alongside many types of mild white fish.

Is the wasabi flavor overpowering?

Not at all! The wasabi brings a gentle kick that warms your palate without overwhelming the subtle sweetness of the potatoes or the delicate fish. You can always start with half the amount and add more to taste.

How do I make this vegetarian?

For a knockout vegetarian version of Pan-Seared Cod with Wasabi Sweet Potato Mash and Miso Glaze, simply swap out the cod for slabs of firm tofu. Sear them just as you would the fish, and generously brush with the miso glaze towards the end.

Can kids enjoy this meal?

Definitely! Kids love the soft, naturally sweet potatoes and mild fish. Just go easy on the wasabi for little ones, and let them help with mashing or plating—the colorful components make it a fun and interactive meal.

What’s a good beverage pairing?

A crisp, chilled white wine (think Sauvignon Blanc or dry Riesling) or a gently sparkling sake pairs fantastically with the umami-rich fish and punchy pickled veggies. For a kid-friendly option, a sparkling water with a splash of yuzu or lime is bright and refreshing.
