Baked Cod with Olives, Lemon and Parsley Recipe

What Is Baked Cod with Olives, Lemon and Parsley?

Baking white fish with olives, lemon and herbs is a coastal cooking habit built around whatever came in fresh that morning. This version skips a heavy sauce, letting briny olives, capers and thin lemon slices baste the cod as it bakes in under twenty minutes. It is a light, mineral-rich dinner that never leaves you feeling heavy the way a fried or breaded fish dish can.

What Makes This Recipe Anti-Inflammatory?

Cod is lean, so it carries far less fat than salmon, but it still delivers EPA and DHA, the omega-3s most closely tied to a calmer inflammatory response, just in smaller amounts.

Olives contribute hydroxytyrosol and oleuropein, polyphenols linked to lower oxidative stress, and a good olive oil brings oleocanthal, a compound shown to act on some of the same pathways as over-the-counter pain relievers. The raw parsley adds apigenin, a flavonoid studied for its calming effect on inflammatory signaling.

Every ingredient is compliant with the AIP elimination phase. There are no grains, legumes, nightshades, dairy, eggs, nuts, seeds or seed-based spices, and unlike the classic Mediterranean version of this dish, which simmers in crushed tomatoes, the acidity here comes entirely from fresh lemon, with no breading anywhere near the fish.

Ingredients

• 4 cod fillets, about 6 ounces each, patted very dry
• 3/4 cup pitted black olives in brine, halved
• 1 lemon, half thinly sliced and half juiced
• 1/2 cup fresh parsley, roughly chopped
• 4 garlic cloves, thinly sliced
• 3 tablespoons olive oil
• 1 tablespoon capers, rinsed and drained
• 1 teaspoon fresh oregano leaves
• 1/2 teaspoon sea salt

Directions

Step 1

Preheat the oven to 400°F and lightly oil a baking dish large enough to hold the fillets in a single layer.

Step 2

Pat the cod dry again with paper towels, front and back. Surface water turns to steam in the oven, and steamed fish falls apart into loose flakes instead of holding together.

Step 3

Arrange the fillets in the dish, thicker pieces toward the center where the heat is steadiest and thinner tail pieces near the edges, since they cook faster and dry out first.

Step 4

Rinse the olives briefly if the brine tastes very salty, since the dish is already salted. Scatter the olives, capers, garlic and lemon slices over the cod, then drizzle with olive oil and sprinkle with oregano and salt.

Step 5

Bake uncovered, with no foil, so the top browns slightly instead of steaming. This takes 12 to 18 minutes depending on thickness, roughly 10 minutes per inch at the fillet’s thickest point. The cod is done when it turns opaque and flakes apart cleanly at the touch of a knife tip.

Step 6

Squeeze the reserved lemon half over the hot fish and scatter the parsley on raw, never baked, or it loses its color and flavor. Serve right away with the pan juices spooned over each fillet.

Q&A

Q1: Is this recipe suitable for the AIP elimination phase?
A1: Yes. Cod, olives, capers, lemon, garlic, parsley, oregano, olive oil and sea salt are all permitted during elimination. There is no black pepper in the ingredient list, and the tomatoes a classic version would use are left out since tomatoes are a nightshade. Read the label on your olives and capers too, since some brands add paprika, preservatives or unlisted flavorings.

Q2: Can I use frozen cod fillets for this recipe?
A2: Yes, thaw it fully in the refrigerator first, then pat it very dry before baking. Frozen fillets hold extra moisture, and skipping that drying step is the most common reason this dish turns out watery instead of firm and flaky.

Q3: What other white fish work in this recipe?
A3: Halibut, snapper, mahi mahi and tilapia all work well here. Pick fillets close to the same thickness as cod so the timing stays accurate, and check thinner pieces a few minutes early, since they cook faster than a thick center cut.

Q4: How do I keep the cod from drying out?
A4: Pat the fish dry before baking, watch it closely after the 12-minute mark, and pull it the moment it flakes with a knife tip. Cod overcooks fast once it turns opaque, so a couple of extra minutes is usually what dries it out.

Q5: What sides pair well with this baked cod?
A5: Roasted asparagus, a simple arugula salad or mashed sweet potato pair well with the briny pan juices. Sautéed greens with garlic also echo the flavors already on the plate without competing with the lemon and olives.
