Tender Baked Cod Loin

I was never really confident baking fish until a neighbor brought over cod loins from the market and showed me how simple it could be. The smell of garlic and paprika filling the kitchen that evening made me realize I'd been overthinking it for years. Now this is one of those recipes I turn to when I want something healthy but don't want to fuss. It's become my quiet weeknight win.

I made this for my sister when she was trying to eat lighter after the holidays, and she couldn't believe something so simple tasted this good. We sat at the table with lemon wedges in hand, squeezing them over the fillets and talking about how we used to think cooking fish was intimidating. That night reminded me that the best meals don't have to be complicated.

Ingredients

• Cod loin fillets: Look for thick, firm fillets that are opaque white and smell clean, not fishy, because fresh fish makes all the difference in texture and flavor.
• Olive oil: This keeps the fish moist during baking and helps the seasonings stick, so don't skimp on it.
• Lemon juice: Freshly squeezed is worth it here because it brightens the whole dish and cuts through the richness of the fish.
• Garlic cloves: Minced finely so it melts into the marinade and gives that savory depth without overpowering the delicate cod.
• Sea salt: I prefer sea salt because it has a cleaner taste and doesn't make the fish taste overly salty.
• Black pepper: Just enough to add a subtle warmth without making it spicy.
• Sweet paprika: This gives a gentle color and a hint of sweetness that complements the fish beautifully.
• Dried thyme: It adds an earthy note that pairs wonderfully with seafood and makes the kitchen smell amazing.
• Fresh parsley: Chopped at the last minute for a burst of color and freshness right before serving.
• Lemon wedges: For squeezing over the top at the table because that extra hit of citrus really brings everything together.

Instructions

Preheat and Prep:

Set your oven to 200 degrees Celsius and line a baking tray with parchment paper so nothing sticks. This also makes cleanup a breeze later.

Dry the Fish:

Use paper towels to pat the cod loins completely dry, then lay them out in a single layer on the tray. Drying them helps the marinade cling better and prevents steaming in the oven.

Make the Marinade:

In a small bowl, whisk together the olive oil, lemon juice, garlic, salt, pepper, paprika, and thyme until it's smooth and fragrant. Taste it if you want to adjust the seasoning before it goes on the fish.

Coat the Fillets:

Use a pastry brush to coat each fillet evenly with the marinade, making sure every surface gets some love. The more evenly you brush, the more evenly it will cook and taste.

Bake Until Flaky:

Slide the tray into the oven and bake for 15 to 18 minutes, checking at the 15 minute mark by gently pressing with a fork to see if it flakes. The fish should be opaque all the way through and reach an internal temperature of 63 degrees Celsius.

Garnish and Serve:

Take the tray out, sprinkle fresh parsley over the top, and serve right away with lemon wedges on the side. The parsley adds a pop of color and the lemon wedges let everyone customize their own plate.

One evening I served this with roasted potatoes and a simple green salad, and my partner said it felt like we were at a seaside restaurant. It's funny how a little lemon and garlic can turn a weeknight dinner into something that feels special and memorable.

Serving Suggestions

This cod pairs beautifully with steamed broccoli, roasted asparagus, or a handful of cherry tomatoes tossed in olive oil. I also love serving it over a bed of quinoa or alongside buttery mashed potatoes when I want something a bit heartier. A crisp white wine or sparkling water with lemon makes it feel like a proper occasion.

Substitutions and Variations

If you can't find cod, haddock or halibut work just as well and have a similar texture. For a bit more punch, try adding a sprinkle of capers or a pinch of red pepper flakes to the marinade. You can also swap the thyme for dill or oregano if that's what you have on hand.

Storage and Reheating

Leftover cod keeps well in an airtight container in the fridge for up to two days, though it's best enjoyed fresh. When reheating, use a low oven or microwave on reduced power to avoid drying it out. I sometimes flake the leftovers into a salad or toss them with pasta for a quick lunch the next day.

• Store in an airtight container in the fridge for up to two days.
• Reheat gently in a low oven or microwave to keep it from drying out.
• Flake leftovers into salads, grain bowls, or pasta for an easy next day meal.
