What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, and substitutions are easy if needed.

• For the Cod Fillets:
  • Cod fillets (about 1 pound / 450 g), skinless and boneless (look for fresh or thawed frozen fish)
  • All-purpose flour (about ½ cup / 65 g) for light coating
  • Garlic powder (1 teaspoon)
  • Salt and freshly ground black pepper (to taste)
  • Olive oil (2 tablespoons) for frying (I prefer Colavita for best flavor)
  • Unsalted butter (2 tablespoons) to enrich the pan sauce
  • Fresh lemon juice (from 1 large lemon) for brightness
  • Minced garlic (3 cloves) for that punch of flavor
  • Fresh parsley, chopped (2 tablespoons) for garnish and freshness
• For the Buttery Mashed Potatoes:
  • Russet potatoes (about 2 pounds / 900 g), peeled and diced
  • Unsalted butter (4 tablespoons), softened (adds richness)
  • Whole milk or cream (½ cup / 120 ml), warmed (use dairy-free milk if needed)
  • Salt and pepper (to taste)
  • Optional: garlic powder (½ teaspoon) for a subtle kick

Pro tip: For a creamier texture, I sometimes swap half the milk for sour cream or Greek yogurt. And if you want a gluten-free twist, almond flour works well as a coating substitute.

Equipment Needed

• Large non-stick skillet or cast-iron pan (for crispy frying)
• Medium saucepan (for boiling potatoes)
• Potato masher or fork (for mashing potatoes)
• Mixing bowls (for dredging and mixing)
• Measuring cups and spoons (for accuracy)
• Sharp knife and cutting board (for prepping lemon and parsley)

If you don’t have a cast-iron pan, a heavy-bottomed stainless steel skillet works fine. Just keep an eye on the heat to prevent sticking. For budget-friendly options, basic non-stick pans do the trick, though you might miss a bit of that intense crispiness. Keeping your pan well-seasoned makes a huge difference in frying success—rustic or fancy, it’s all about that hot, even surface.

Preparation Method

1. Prep the potatoes: Peel and dice 2 pounds (900 g) of russet potatoes into roughly 1-inch cubes. Place them in a large saucepan and cover with cold water by an inch. Add a pinch of salt. Bring to a boil over high heat, then reduce to medium and simmer for 15-20 minutes until fork-tender.
2. Drain and mash: Drain potatoes well and return them to the hot pot. Add 4 tablespoons softened unsalted butter and ½ cup (120 ml) warmed milk or cream. Mash using a potato masher or fork until smooth but still a bit rustic (don’t overwork!). Season with salt, pepper, and optional garlic powder. Keep warm on very low heat or cover.
3. Prepare the cod coating: In a shallow dish, combine ½ cup (65 g) all-purpose flour, 1 teaspoon garlic powder, salt, and pepper to taste. Mix well.
4. Pat dry the cod fillets: Using paper towels, gently pat 1 pound (450 g) of cod fillets dry to remove excess moisture. This helps achieve maximum crispiness.
5. Dredge the fillets: Lightly coat each fillet in the seasoned flour mixture, shaking off any excess.
6. Heat the pan: Warm 2 tablespoons olive oil over medium-high heat in your skillet until shimmering but not smoking.
7. Fry the cod: Carefully place fillets in the pan (don’t crowd!) and cook for about 3-4 minutes per side until golden brown and cooked through (internal temp about 145°F / 63°C). Adjust heat as needed to avoid burning. Remove fillets to a warm plate.
8. Make the lemon garlic sauce: Lower heat to medium and add 2 tablespoons unsalted butter to the pan. Once melted, add 3 cloves minced garlic and sauté for 30 seconds until fragrant (don’t let it burn!). Pour in fresh lemon juice from 1 lemon, stir, and let it simmer for a minute to marry flavors.
9. Finish and serve: Spoon the lemon garlic sauce over the crispy cod fillets. Garnish with chopped fresh parsley. Serve alongside buttery mashed potatoes. Enjoy immediately for best texture.

Pro tip: If you notice your coating isn’t as crispy as you’d like, make sure your fillets are well dried before dredging and your pan is hot enough before frying. Also, avoid flipping too early—patience pays off!

Cooking Tips & Techniques

Getting that perfect crunch on cod fillets is all about temperature and timing. I learned this the hard way after a few soggy attempts! Make sure your pan is properly heated before adding the fish. Too low, and you’ll end up steaming instead of frying; too high, and the coating burns before the inside cooks.

Use a light hand when coating the fish in flour—too thick and it gets gummy. Also, patting the fish dry is a small step that makes a huge difference in crispiness.

When making mashed potatoes, warm your dairy before adding. Cold milk or butter cools the potatoes and makes the mash gluey. And don’t overmix! Overworking potatoes releases starch and leads to a gluey texture.

Timing is key: start boiling your potatoes first since they take the longest, then prep the fish while they cook. That way, everything finishes around the same time without stress.

Variations & Adaptations

This recipe is super flexible, so you can customize it to your liking or dietary needs.

• Gluten-free option: Swap all-purpose flour with almond flour or rice flour for dredging. The coating will be slightly different but still deliciously crispy.
• Spicy twist: Add a pinch of cayenne or smoked paprika to the flour mix for a subtle heat that pairs beautifully with lemon.
• Herb swap: Instead of parsley, try fresh dill or thyme for a different flavor profile that complements the cod.
• Garlic mashed potatoes: Roast garlic cloves and mash them into the potatoes for a deeper, sweeter garlic flavor.
• Alternative cooking methods: If you prefer oven-baking, coat the fillets and bake at 425°F (220°C) on a parchment-lined tray for about 12-15 minutes, flipping halfway. Finish with lemon garlic butter drizzled on top.

I once tried this recipe using sweet potatoes for the mash and added a bit of honey to the lemon butter. It was unexpectedly delightful—sweet and savory in a harmonious dance.

Serving & Storage Suggestions

Serve the cod fillets hot and fresh from the pan, drizzled generously with the lemon garlic butter. The buttery mashed potatoes should be creamy and warm, offering the perfect base for those crispy fillets. Garnish with extra parsley or lemon wedges for a pop of color and freshness.

This dish pairs beautifully with a crisp green salad or roasted asparagus and a chilled glass of white wine, like Sauvignon Blanc or Chardonnay.

For leftovers, store fish and potatoes separately in airtight containers in the refrigerator for up to 2 days. Reheat mashed potatoes gently in the microwave or on the stove with a splash of milk to loosen them up. Reheat cod in a low oven (around 300°F / 150°C) for 10 minutes to keep the coating crisp—microwaving tends to make it soggy.

Flavors in the mashed potatoes tend to mellow and deepen after a day, so leftovers can taste even better the next day if reheated carefully.

Nutritional Information & Benefits

This meal offers a balanced combination of lean protein and comforting carbs. Cod is a fantastic source of low-fat protein, rich in vitamins B6 and B12, and provides essential omega-3 fatty acids that support heart and brain health.

The mashed potatoes provide potassium and vitamin C, especially if you keep the skins on (if you like). Using unsalted butter and controlling salt keeps sodium levels in check, and you can always substitute dairy-free options to suit dietary needs.

This recipe is naturally gluten-free if you swap the flour and is relatively low-carb if you adjust the potato portion or substitute cauliflower mash. It’s a wholesome, satisfying dinner that’s kid-friendly and adult-approved.

Conclusion

FAQs

Can I use other types of fish for this recipe?

Absolutely! White, flaky fish like haddock, tilapia, or pollock work well. Just adjust cooking times slightly based on thickness.

How do I prevent the cod from sticking to the pan?

Make sure your pan is hot before adding the fish and use enough oil. Patting the fillets dry and not moving them too early helps form a crust that naturally releases.

Can I make the mashed potatoes ahead of time?

Yes, you can make them a few hours before serving. Keep them warm in a covered dish or reheat gently with some milk to restore creaminess.

Is it okay to bake the cod instead of frying?

Yes, baking at 425°F (220°C) for 12-15 minutes works well for a lighter version. Just remember to add the lemon garlic butter after baking for best flavor.

What can I serve alongside this dish?

Roasted or steamed vegetables, a fresh green salad, or even a light quinoa salad complement this dish nicely. A crisp white wine also pairs beautifully.
