Ingredients Needed
- 4 cod fillets, about 6 ounces each
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 cup almond flour
- 2 tablespoons olive oil
- 4 tablespoons unsalted butter
- 1/4 cup fresh lemon juice
- 1/2 cup chicken broth
- 1/4 cup capers, drained
- 2 tablespoons fresh parsley, chopped
- Lemon slices, for garnish
Ingredient Notes
Cod works beautifully here because it has a mild flavor and a tender, flaky texture that absorbs the lemon butter sauce well. Almond flour gives the fish a very light coating and helps it brown without adding many carbs. Fresh lemon juice is important because it gives the sauce its clean, bright flavor. Chicken broth adds savory depth and keeps the sauce balanced instead of overly sharp. Capers bring that classic piccata flavor, while parsley adds freshness right at the end.
- Use halibut, haddock, or tilapia if cod is not available.
- Swap almond flour with coconut flour, using a lighter amount since it absorbs more moisture.
- Replace chicken broth with vegetable broth if that is what you have on hand.
- Add a small splash of dry white wine to the sauce for deeper flavor.
- Use ghee instead of butter if you prefer.
- Finish with fresh dill instead of parsley for a different herbal note.
How to Make It
Step 1:
Pat the cod fillets dry with paper towels. This helps the coating stick better and also helps the fish sear properly instead of steaming.
Step 2:
Season both sides of the cod evenly with salt and black pepper.
Step 3:
Spread the almond flour onto a plate or shallow dish. Lightly dredge each fillet in the almond flour, then shake off any excess so the coating stays thin and delicate.
Step 4:
Heat the olive oil in a large skillet over medium-high heat until it looks hot and shimmery.
Step 5:
Place the cod fillets into the skillet in a single layer. Cook for 3 to 4 minutes on the first side, or until the bottom turns golden and releases easily from the pan.
Step 6:
Carefully flip the fillets with a spatula and cook for another 3 to 4 minutes, or until the fish is cooked through and flakes easily with a fork. Transfer the cod to a plate and set it aside.
Step 7:
Lower the heat to medium. Add the butter to the same skillet and let it melt while scraping up any browned bits from the bottom of the pan. Those bits add extra flavor to the sauce.
Step 8:
Stir in the fresh lemon juice and chicken broth. Bring the mixture to a gentle simmer and let it cook for about 3 minutes so the sauce reduces slightly and becomes more concentrated.
Step 9:
Add the drained capers and stir to combine. Taste the sauce and adjust with a little extra salt or pepper if needed.
Step 10:
Return the cod fillets to the skillet. Spoon the warm lemon butter sauce over the fish and let everything cook together for about 2 more minutes so the flavors meld.
Step 11:
Sprinkle the chopped parsley over the top and garnish with lemon slices.
Step 12:
Serve the Keto Cod Piccata with Capers and Lemon Butter right away while the fish is hot and flaky and the sauce is glossy.
- Dry the cod well before seasoning so it sears instead of steaming.
- Use a well-heated skillet to help the fish develop a golden crust and release more easily.
- Keep the almond flour coating light, because too much can turn gummy.
- Do not move the fish too early in the pan or it may break apart.
- Reduce the sauce gently instead of boiling it aggressively.
- Spoon the sauce over the fish at the end so every fillet stays moist and flavorful.
- Do not skip patting the fish dry, because excess moisture prevents a good sear.
- Do not overcrowd the skillet or the fillets may steam instead of brown.
- Do not overcook the cod, or it will turn dry and lose its delicate texture.
- Do not use bottled lemon juice if you can avoid it, because the sauce tastes best with fresh lemon.
- Do not add too much almond flour, or the coating can become heavy.
- Do not boil the butter sauce too hard, or it can separate.
Serving Suggestions + Easy Variations
This Keto Cod Piccata with Capers and Lemon Butter pairs beautifully with simple sides that soak up the extra sauce. Serve it with cauliflower mash, roasted asparagus, sautéed spinach, or zucchini noodles for a complete low-carb meal. If you want something a little heartier, try it with roasted broccoli or a crisp green salad dressed with olive oil and lemon.
For easy variations, add a splash of white wine to the sauce when you pour in the lemon juice and broth for deeper flavor. Stir in a little garlic powder or extra black pepper if you want a stronger savory edge. You can also add a few halved cherry tomatoes for freshness and color. If you enjoy richer sauces, swirl in one extra tablespoon of butter at the end right before serving.
- You can season and dredge the cod up to a few hours ahead and keep it refrigerated until cooking time.
- The lemon butter sauce can be made slightly ahead, then rewarmed gently in the skillet.
- Store leftovers in an airtight container in the refrigerator for up to 2 days.
- Reheat gently on the stovetop over low heat so the fish does not dry out.
- Spoon extra sauce over the cod while reheating to help keep it moist.
- This dish is best enjoyed fresh, because cod is most tender right after cooking.
