What You’ll Need for Keto Cod

- 1 lb. cod (about 4 pieces, fresh or thawed)
- Salt and pepper (to taste, for seasoning)
- 2 teaspoons minced garlic (fresh or jarred)
- 1 tablespoon capers (or more if you love their tangy flavor)
- 2 tablespoons butter (unsalted, or substitute with ghee for a richer taste)
- Juice from 1 small lemon (about 2 tablespoons, fresh is best)
How to Make Keto Cod
- Heat the skillet: Place a nonstick skillet over medium heat and let it warm up.
- Season the cod: Pat the cod dry with a paper towel, then generously season both sides with salt and pepper.
- Cook the cod: Add the cod to the skillet and cook for 5-6 minutes per side, or until the fish is opaque and flakes easily with a fork. Transfer the cooked cod to a plate and set aside.
- Make the sauce: In the same skillet, add the minced garlic, capers, butter, and lemon juice. Cook for 2-3 minutes, stirring occasionally, until the sauce thickens slightly.
- Finish and serve: Remove the skillet from heat. Spoon the lemon caper sauce over the cooked cod. Serve warm with your favorite keto-friendly sides, like roasted vegetables or a fresh salad.
Perfect Pairings: Keto-Friendly Sides to Serve with Cod
This keto cod recipe pairs beautifully with low-carb sides to keep your meal light and satisfying. Try serving it with zucchini noodles tossed in olive oil, roasted asparagus sprinkled with Parmesan, or a fresh avocado salad. For a heartier option, cauliflower rice sautéed with garlic and herbs makes a great base to soak up the lemon caper sauce.
Quick Storage and Reheating Tips
Store leftover cod in an airtight container in the fridge for up to 2 days. To reheat, gently warm it in a skillet over low heat to prevent overcooking. If the sauce thickens too much, add a splash of water or lemon juice to bring it back to life. Avoid microwaving, as it can make the fish rubbery.
Easy Recipe Variations to Mix It Up
Customize this dish to suit your taste! Swap cod for halibut or salmon for a richer flavor. If you’re not a fan of capers, try chopped olives or sun-dried tomatoes for a tangy twist. For a creamier sauce, stir in a tablespoon of heavy cream or cream cheese at the end.
Time-Saving Tips for Busy Cooks
To save time, prep your ingredients ahead of time. Mince the garlic and juice the lemon in advance, and store them in the fridge. If you’re cooking for a crowd, use a large skillet or cook the cod in batches to avoid overcrowding the pan, which can slow down the cooking process.
Essential Equipment for Perfect Cod
A nonstick skillet is key for this recipe to ensure the cod doesn’t stick and cooks evenly. If you don’t have one, use a well-seasoned cast iron pan or stainless steel skillet with a bit of extra butter. A fish spatula is also handy for flipping the delicate fillets without breaking them.
