Ingredients Needed

This flavorful lemon garlic butter cod recipe relies on simple, fresh ingredients that come together for a seriously satisfying dinner. You won’t need any specialty items, and there’s plenty of room for substitutions if you’re missing something.

• Cod fillets (4 pieces, about 6 oz / 170g each): Fresh or frozen, just make sure to thaw thoroughly if frozen. I prefer wild-caught for the best texture and flavor.
• Salt (1/2 tsp / 3g): For seasoning the fish and enhancing flavors.
• Black pepper (1/4 tsp / 1g): Adds a gentle kick and balances the tang of the lemon.
• All-purpose flour (1/4 cup / 30g): For lightly dredging the cod and giving it a golden crust. You can use gluten-free flour if needed.
• Unsalted butter (4 tbsp / 56g): The hero of the sauce! Adds richness and helps carry the garlic and lemon flavors.
• Olive oil (2 tbsp / 30ml): For searing the fish and preventing sticking. I love using extra-virgin for flavor, but any mild oil works.
• Garlic cloves (4 large, minced): Fresh is best here—pre-minced just doesn’t pack the same punch.
• Lemon (1 large, juiced and zested): Both the juice and zest add brightness. If you love extra tang, use two lemons!
• Chicken or vegetable broth (1/3 cup / 80ml): Helps make a silky sauce. You can use water in a pinch, but broth adds depth.
• Fresh parsley (2 tbsp / 8g, chopped): For garnish and a pop of color/flavor. If you’re out, chives or dill work too.

Optional add-ins and swaps:

• Red pepper flakes (1/8 tsp): For a little heat in the sauce.
• Capers (1 tbsp): Toss these in for a briny punch—so good if you like bold flavors.
• Dairy-free butter: Works if you’re lactose-intolerant or vegan (just swap cod for tofu or tempeh).
• Other white fish: If cod isn’t available, haddock, halibut, or tilapia are great alternatives.

I’ve found that using high-quality butter (like Kerrygold) makes the sauce extra creamy. And, if you want a gluten-free dinner, simply swap the flour for a 1:1 gluten-free blend—no one will know the difference!

Equipment Needed

• Large skillet (preferably nonstick or stainless steel): Makes searing the cod easier and helps build a golden crust. I’ve used cast iron, too—it works, but can stick if you’re not careful.
• Fish spatula: Thin and flexible for flipping delicate fillets without breaking them. If you don’t have one, use a regular spatula, but go slow.
• Mixing bowls: For dredging the cod and mixing the sauce ingredients.
• Microplane or zester: For getting fine lemon zest—try the back of a box grater if you don’t own one.
• Cutting board and sharp knife: For prepping garlic, parsley, and lemons. I like a small paring knife for zesting.
• Measuring spoons and cups: For accurate quantities (I eyeball sometimes, but precision really helps with this recipe!).

If you’re just starting out, don’t worry about fancy gear. A sturdy pan and basic utensils work fine! I clean my fish spatula right after each use to prevent odors—works like a charm. Budget-friendly pans from stores like Target or IKEA do the trick just as well as pricey brands.

Preparation Method

Let’s get cooking! Here’s how I make lemon garlic butter cod step by step. I’ll throw in a few notes and tips I’ve learned from trial (and the occasional error).

1. Prep the cod: Pat cod fillets dry with paper towels. Sprinkle both sides evenly with salt and pepper. (Dry fish sears better—don’t skip this!)
2. Dredge the fillets: Place flour in a shallow bowl. Lightly coat each fillet in flour, shaking off excess. This helps create a golden crust and keeps the fish from sticking.
3. Sear the fish: Heat 2 tbsp olive oil in a large skillet over medium-high heat. When hot (shimmering but not smoking), add cod fillets. Cook for 2-3 minutes per side, until golden brown and just cooked through. (Cod is done when it flakes easily and turns opaque.) Transfer to a plate and cover loosely with foil.
4. Make the sauce: Reduce heat to medium. Add 4 tbsp butter to the pan. When melted, stir in minced garlic. Sauté for 1 minute until fragrant but not browned. Add lemon juice, zest, and broth. Simmer for 2-3 minutes, stirring to scrape up any browned bits. If the sauce looks thin, simmer another minute to thicken slightly.
5. Return cod to pan: Carefully place cod fillets back into the skillet, spooning sauce over the tops. Cook for 1 minute to warm through and let flavors meld.
6. Finish and serve: Sprinkle with chopped parsley. Taste the sauce and adjust lemon, salt, or pepper if needed. (I usually add a pinch more lemon for extra zing.) Serve hot, spooning extra sauce over each fillet.

Time estimates: Prep: 10 minutes, Cook: 15-20 minutes, Total: ~30 minutes

Troubleshooting: If the fish sticks, make sure the pan and oil are hot before adding cod. If the sauce breaks (looks oily), whisk in a splash of broth or water to bring it back together. Cod can overcook fast—look for flakes and opaque flesh, not dry edges.

My personal tip: I zest the lemon before juicing—it’s way easier! And if you’re multitasking, prep the parsley while the fish cooks. The key is not to rush the sear—patience pays off with a crispy, flavorful crust.

Cooking Tips & Techniques

Cooking cod isn’t tricky, but a few small moves make a big difference. Here’s what I’ve learned along the way (sometimes the hard way!).

• Don’t overcrowd the pan: Sear cod in batches if needed. Crowding leads to steaming, not crisping, and you’ll miss out on that golden crust.
• Use room temperature butter: It melts more evenly and prevents the sauce from splitting. If you’re short on time, microwave cold butter for 10 seconds.
• Go low and slow with garlic: Garlic burns fast. Add it after the butter melts, and stir constantly for the best flavor.
• Fish flakes, not falls apart: Cod is delicate. Use a thin spatula and flip gently. If it breaks, don’t worry—broken pieces are just as tasty!
• Multitasking tip: While the fish cooks, prep your sides—rice, veggies, or salad. The sauce comes together in minutes, so you’ll have time to finish everything at once.
• Consistency matters: Pat the cod dry! Wet fish won’t crisp up. Also, taste the sauce before serving—sometimes lemons are more tart, so adjust as needed.

Once, I burned the garlic by cranking the heat too high—let’s just say, bitter sauce isn’t the move. Now, I always drop the heat after searing the fish. And if the butter starts to brown, I swirl in a splash of broth for a silky finish.

Short on time? Skip the flour dredge for a lighter feel—just know the crust will be softer. These little tweaks make the lemon garlic butter cod recipe flexible for any cook.

Variations & Adaptations

This lemon garlic butter cod recipe is a blank canvas for your creativity! Here are some ways to switch things up:

• Gluten-Free: Swap all-purpose flour for a gluten-free flour blend or almond flour. The crust will be just as crispy.
• Dairy-Free: Substitute vegan butter and skip the flour dredge (or use a dairy-free alternative). The sauce will be lighter but still full of flavor.
• Spicy Twist: Add 1/4 tsp red pepper flakes to the butter sauce for a gentle kick. My husband loves this version for an extra punch.
• Herb Swap: Try dill or thyme instead of parsley, especially if you’re serving with potatoes or grains. It changes the flavor profile in a fun way.
• Alternative Fish: Use haddock, halibut, or tilapia if cod isn’t available. Cooking time may vary slightly—thicker fillets need a minute or two longer.

Allergen note: You can use gluten-free flour and dairy-free butter for most dietary needs. If you have lemon allergies, try lime for a different zing. Personally, I love adding capers when I want a briny, Mediterranean vibe—just toss them into the sauce with the garlic.

Roasting method: Instead of pan-searing, bake the dredged cod at 400°F (200°C) for 12-15 minutes, then pour the warm butter sauce over before serving. It’s hands-off and perfect for larger batches!

Serving & Storage Suggestions

This cod is best served hot, straight from the skillet, when the butter sauce is glistening and the fish is flaky. I love to plate it on a warm serving platter, sprinkle with fresh parsley, and add a few lemon slices for color.

• Serving ideas: Pair with steamed rice, roasted potatoes, or a crisp green salad. A side of sautéed asparagus or green beans works beautifully. For a cozy dinner, serve with garlic bread to soak up the sauce.
• Beverage pairings: A chilled sauvignon blanc or sparkling water with lemon rounds out the meal.
• Storage: Leftovers keep in an airtight container in the fridge for up to 2 days. The sauce may solidify—just reheat gently in a skillet over low heat with a splash of broth.
• Freezing: I don’t recommend freezing cooked cod—texture changes and it gets watery. If you must, freeze the fillets separately and make fresh sauce when ready.
• Reheating: Warm in a skillet on low, spooning sauce over the top to keep the fish moist. Avoid microwaving—it can dry out the cod.

Flavors actually deepen overnight, so leftovers taste great the next day. Just don’t forget a little extra lemon before serving!
