Side Dishes
This cod potatoes recipe delivers a perfect marriage of crispy, golden potato crowns with tender flaky cod—each bite balanced between crunchy exterior and fluffy pink centers.
The secret lies in a cornmeal crust that creates that signature texture while keeping the potatoes light and airy inside, paired with a simple pan-searing technique for the cod that ensures it stays moist and delicate.
I developed this dish after years of experimenting with seafood and potato combinations, and it's now a staple in my weekly rotation for its ability to transform simple ingredients into something restaurant-worthy.
The beauty of this recipe is its simplicity—just a handful of ingredients come together to create a dish that feels indulgent without requiring advanced techniques. You'll start with baby potatoes (their small size ensures even cooking), tossed in cornmeal and herbs before baking until crispy.

Ingredients for cod potato
Crispy potato crowns meet tender cod fillets—just eleven ingredients transform simple seafood into restaurant-worthy magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Baby Potatoes 🥔 | 2 lbs | Halved if larger than 1.5 inches |
| Fine Yellow Cornmeal 🌽 | ¾ cup | Bob's Red Mill preferred for texture |
| Fresh Dill 🌿 | ⅓ cup | Chopped, stems removed |
| Lemon Zest 🍋 | 1 tbsp | From 1 large organic lemon |
| Extra-Virgin Olive Oil 🫒 | ⅓ cup | Light, fruity variety |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Coarsely cracked peppercorns |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For seasoning and crust |
| Cod Fillets 🐟 | 2 pieces | 6-8 oz each, skin-on |

The potatoes are the star here, so baby potatoes are non-negotiable—their uniform size ensures perfect even cooking. Grab the smallest bag you can find at Whole Foods or your local market, as larger potatoes will take forever to crisp. The cornmeal? Bob's Red Mill fine yellow is my go-to for that signature crunch—it's worth the slight splurge over store-brand versions. Fresh dill is a must; Trader Joe's sells it in those little plastic containers, but if you're feeling fancy, hit the farmers market for the brightest green stems. And that lemon zest? Organic lemons have more vibrant flavor, but conventional works in a pinch. Just make sure it's freshly zested—pre-grated zest loses its magic fast.
No cod fillets? Haddock or halibut work perfectly—they have a similar delicate texture. The skin should be golden brown, not gray or slimy, and the flesh should be translucent with just a hint of pink. If you can't find fresh cod, frozen works too, just thaw it overnight in the fridge. Short on dill? Fresh parsley at double the amount gives a similar bright finish. The olive oil matters here—use something you'd drizzle on bread, not that cheap cooking oil. And that butter? European-style unsalted melts more cleanly, but regular butter works in a bind. Just make sure it's cold when you cube it for searing.
These potatoes reheat beautifully—just pop them in a 375°F oven for 10-12 minutes until crispy again. The cod should be eaten fresh, but if you have leftovers, store it in an airtight container with a paper towel to absorb moisture. Both keep for 2 days in the fridge, but the potatoes are even better the next day once they've had time to crisp up properly. For meal prep, I like to portion the potatoes and cod separately so they stay at their peak texture. And that lemon juice? Squeeze it fresh right before serving—it makes all the difference.

Step-by-step instructions for crispy cornmeal crowns with fluffy pink centers
Transform humble baby potatoes into golden, crunchy crowns with tender interiors—this method guarantees restaurant-quality texture every time.
Prepare the Potatoes for Perfect Crispiness
Preheat your oven to 425°F and line two baking sheets with parchment paper. Rinse the 2 lbs baby potatoes under cold water, then scrub them thoroughly with a vegetable brush to remove any dirt. Halve any potatoes larger than 1.5 inches—this ensures even cooking and maximum crispiness.
Place the potatoes in a large bowl and toss them with 0.33 cup extra-virgin olive oil until every surface glistens. Sprinkle with 1 tsp freshly ground black pepper and 1 tsp diamond crystal kosher salt, then toss again until evenly coated. The oil creates a barrier that prevents the potatoes from drying out while the seasoning penetrates the skin.
Create the Crispy Cornmeal Crust
In a shallow bowl, combine 0.75 cup fine yellow cornmeal with 0.5 tsp diamond crystal kosher salt (reserving the remaining 1 tsp for later). The cornmeal will form the irresistible crunchy exterior that sets this dish apart. Toss each potato half in the cornmeal mixture until fully coated, pressing gently to adhere the cornmeal to the skin.
Arrange the cornmeal-coated potatoes on the prepared baking sheets in a single layer, leaving about 1 inch between each piece. This spacing allows hot air to circulate freely, ensuring even browning. For extra flavor, sprinkle the remaining 1 tsp diamond crystal kosher salt over the top of the potatoes.
Roast Until Golden and Crisp
Roast the potatoes in the preheated oven for 30-35 minutes, flipping them halfway through cooking at the 15-minute mark. You'll know they're ready when the edges are deep golden brown and the cornmeal crust is crisp to the touch. The internal temperature should reach 205°F—this ensures the potatoes are tender all the way through.
Here's where attention to detail pays off: If you see any potatoes browning too quickly, rotate the baking sheets and continue cooking. The cornmeal crust should be uniformly crispy, not burnt. Remove the potatoes from the oven and let them rest on the baking sheets for 5 minutes—this resting period allows the juices to redistribute, preventing them from leaking out when sliced.
Sear the Cod Fillets for Flaky Perfection
While the potatoes roast, heat a large skillet over medium heat until it's hot but not smoking. Add the 2 tbsp unsalted butter and allow it to melt completely, then add the 2 pieces cod fillets, skin-side down. Cook for 3-4 minutes until the skin is golden brown and crispy, then carefully flip the fillets and cook for another 2-3 minutes until they're opaque and flaky.
Remove the cod from the skillet and set it aside to rest. In the same skillet, add 4 cloves sliced garlic cloves and sauté for 30 seconds until fragrant. Stir in 2 tbsp fresh lemon juice and 1 tbsp lemon zest, then pour the mixture over the cod. The bright citrus notes will cut through the richness of the butter and complement the crispy potatoes beautifully.
Assemble and Garnish for Maximum Impact
Slice the rested potatoes into wedges and arrange them on a large serving platter. Place the seared cod fillets on top of the potatoes, skin-side up, and drizzle any remaining pan juices over the top. Sprinkle the 0.33 cup chopped fresh dill evenly over the potatoes and cod, adding a fresh, herbal note that ties everything together.
Serve immediately while the potatoes are still crisp and the cod is flaky. The contrast of the crunchy cornmeal crust with the fluffy, pink centers of the potatoes creates an unforgettable texture experience. Pair with a simple arugula salad dressed with a touch of extra-virgin olive oil and lemon juice for a complete, balanced meal.
Pro Tips For Making Cod Potato
- CRISP THE POTATOES FIRST: Toss the baby potatoes in cornmeal before roasting, not after—this isn’t just for coating. After boiling or parboiling, spread them on a baking sheet in a single layer and roast at 425°F (220°C) for 15 minutes. The extra dryness from the oven makes them absorb the olive oil and lemon zest better later. I used to skip this, and the potatoes always tasted damp no matter how much I seasoned them afterward.
- STORE-BOUGHT DILL? CHOP IT FINE: Fresh dill loses its punch fast, so if you’re not using it all, chop it finely and freeze it in olive oil in an ice cube tray. When you need it, just grab a cube—it’ll thaw quickly and keep that bright flavor. I learned this the hard way after letting a bunch of dill wilt in the fridge, only to realize I’d overestimated how much I’d use.
- DON’T OVERMIX THE CORNMEAL: When coating the potatoes, use just enough cornmeal to lightly adhere—think dusting, not gluing. Overmixing makes the coating gummy, and the potatoes won’t get that perfect crunch. Pat them dry first with a kitchen towel, then toss gently in a bowl with the cornmeal. This isn’t a batter; it’s a whisper of texture.
- LEMON ZEST NEEDS TIME: Zest the lemon right before tossing it with the olive oil—fresh zest oxidizes fast, turning bitter within minutes. If you’re prepping ahead, zest the lemon and store it in the freezer in a tiny container, then add it just before serving. I was skeptical until I tried it; the difference in brightness is noticeable.
Regional styles of this cod potato
New England Style
In coastal New England, cod and potatoes are a match made in heaven, often served with a buttery, herbed crust. Here, I replace the cornmeal with a mix of panko breadcrumbs and grated Parmesan cheese for extra richness.
Toss the potatoes in this mixture before roasting at 400°F for 25 minutes until golden.
The cod is traditionally baked with a lemon-herb butter sauce—mix 2 tbsp melted butter, 1 tbsp lemon juice, and 1 tsp chopped parsley—poured over the fillets before baking at 375°F for 12-15 minutes. 🍋
Scottish Crispy Tatties
Scotland’s answer to crispy potatoes is tatties, often served with haddock or cod. For this version, I use Yukon Gold potatoes (instead of baby potatoes) and coat them in a mix of flour, salt, and a pinch of smoked paprika for a subtle smoky depth.
Roast at 425°F for 40 minutes, flipping halfway, until deeply caramelized. The cod is pan-fried in lard or beef fat—traditional for a richer flavor—until the skin is crispy. Serve with a side of creamy mashed neeps (turnips) for a true Scottish-inspired plate. 🏴
Mediterranean Lemon-Herb Twist
In Mediterranean coastal regions, cod and potatoes are often elevated with bright citrus and aromatic herbs. Here, I toss the potatoes in a mix of cornmeal and dried oregano before roasting, then finish with a sprinkle of feta cheese—about 2 tbsp crumbled—while still hot.
The cod is marinated in lemon juice, olive oil, and fresh oregano for 30 minutes before pan-searing. A drizzle of chili-infused olive oil (mix 1 tbsp olive oil with ½ tsp red pepper flakes) ties it all together. 🌿
Southern U.S. Smoky Version
For a Southern-inspired take, I swap the cornmeal for a mix of crushed pork rinds—about ½ cup—and smoked paprika to add a crispy, smoky crust. Roast the potatoes at 450°F for 30 minutes until extra crispy.
The cod is seasoned with Cajun spices—a mix of paprika, garlic powder, and cayenne—before pan-searing. Serve with a side of collard greens for a full Southern feast. 🌶️
Nordic Dill & Mustard
In Nordic cuisine, dill and mustard shine in seafood dishes. Here, I toss the potatoes in a mix of cornmeal and Dijon mustard—about 1 tbsp—for a tangy twist. Roast as usual, then finish with a sprinkle of fresh dill.
The cod is marinated in a mix of Dijon mustard, white wine, and fresh dill for 20 minutes before searing. Serve with a side of lingonberry jam for a sweet-tart contrast. 🇸🇪

Frequently asked questions
Can I use regular potatoes instead of baby potatoes?
Baby potatoes are ideal because their small size ensures even cooking and maximum crispiness. For larger potatoes, cut them into 1-inch chunks and increase roasting time by 5-10 minutes to achieve the same texture. The cornmeal crust will still work, but the internal fluffiness may vary.
How do I prevent the cod from drying out?
Never overcook the cod! It's done at 145°F internal temperature (about 3-4 minutes per side). Pat it dry before cooking and use a light pan-sear with butter—not oil—to keep it moist. Let it rest 2-3 minutes after cooking to redistribute juices.
Can I make this ahead of time?
The potatoes reheat beautifully at 375°F for 10-12 minutes until crispy again. Store them separately from the cod (which is best fresh) in an airtight container. The flavors actually improve overnight as the cornmeal crust firms up.
What if I don't have cornmeal?
Use crushed pork rinds (½ cup) or panko breadcrumbs for a crispy alternative. For a softer texture, try semolina or fine breadcrumbs. Just note the flavor will differ slightly—cornmeal gives that signature nutty crunch.
How do I know when the potatoes are perfectly crispy?
Look for deep golden brown edges and a crisp sound when tapping them. The internal temperature should reach 205°F. If they're browning too fast, rotate the tray and cover loosely with foil for the last 5 minutes.
