Baked Cod Buttery Cracker Crumbs

There's something about the smell of butter hitting a hot oven that makes me feel like I'm finally doing something right in the kitchen. One weeknight, I had four cod fillets sitting in the fridge and about twenty minutes before hungry people would arrive at my door, and I remembered my neighbor casually mentioning how she tops her fish with crushed crackers. I was skeptical—it sounded too simple—but I melted some butter, crushed up what I had in the pantry, and threw it all together. When it came out of the oven, golden and crispy, I realized I'd stumbled onto something that would become a regular rotation in my house.

I made this for my sister's family last summer, and her youngest, who claims to hate fish, asked for seconds. She sat there picking at the crumbs and eating every flaky piece, and I watched my brother-in-law try not to laugh at her sudden change of heart. That's when I knew this recipe had staying power—it converts people who think they don't like fish.

Ingredients

• Cod fillets: Look for thick, evenly-sized fillets so everything bakes at the same pace; if one piece is twice as thick as another, it won't cook evenly.
• Kosher salt and fresh black pepper: These season the fish itself, so don't skip them or the whole dish tastes flat.
• Lemon juice: Brightens the fish and cuts through the richness of the butter topping.
• Buttery crackers: Ritz crackers work beautifully, but any salted, buttery cracker will do; the butter in the cracker itself is part of what makes the topping golden and crispy.
• Unsalted butter, melted: This is what binds everything together and creates that golden crust.
• Fresh parsley: Adds a grassy note that keeps the topping from tasting one-dimensional.
• Garlic powder: Gives depth without overpowering the delicate fish flavor.
• Lemon zest: One of those small touches that people taste but can't quite identify, which makes them come back for more.

Instructions

Get your oven ready:

Preheat to 400°F and line your baking sheet with parchment paper or give a baking dish a light coating of oil. This prevents sticking and makes cleanup feel like less of a chore afterward.

Dry and season the fish:

Pat those fillets completely dry with paper towels—moisture is the enemy of a crispy topping. Arrange them on your prepared sheet, drizzle with lemon juice, then season evenly with salt and pepper, making sure to hit every edge.

Make the topping:

In a bowl, combine your crushed crackers, melted butter, parsley, garlic powder, and lemon zest, stirring until the crumbs are evenly moistened and start clumping together slightly. It should feel a bit like wet sand.

Top the fillets:

Spoon the crumb mixture generously over each fillet, then press gently with the back of a spoon so it sticks. Don't pack it down too hard or it becomes dense; you want it to stay light and crunchy.

Bake until golden:

Slide everything into the oven for 15 to 20 minutes—the exact time depends on fillet thickness. The fish is done when it flakes easily with a fork and the topping is golden brown and looks like it might crunch when you bite into it.

Plate and serve:

Transfer to serving plates while everything is still warm, add a lemon wedge and a scatter of fresh parsley if you want it to look pretty, and eat it before it gets cold.

Save

I remember plating this for a friend who'd been having a rough week, and watching her take that first bite and just close her eyes for a second made me realize how food does that—it gives you a moment to step out of whatever's weighing on you. That's what this dish is to me now: a small kindness you can make for someone, including yourself.

Why This Topping Works

The butter in the crackers and the melted butter you add create a double layer of richness that sounds heavy but isn't, because the fish underneath is so lean and flaky. The garlic powder adds umami without being loud about it, and the parsley keeps everything tasting fresh instead of fried. It's the kind of topping that sounds simple until you realize it's the reason people ask for the recipe.

Variations and Swaps

I've made this with crushed saltines when I didn't have Ritz, and it was great but a little less rich. I've also tried panko breadcrumbs mixed with melted butter and a pinch of Old Bay, which pushes it in a more seafood-forward direction. The formula stays the same: dry your fish, season it, top it with buttery breadcrumbs mixed with seasonings, and bake. You can swap the fish too—haddock, halibut, or even tilapia all work; just pay attention to thickness so you're not guessing on bake time.

Serving and Pairing Ideas

This dish is flexible enough to fit into almost any meal plan. Steamed broccoli or green beans alongside it feel like the move, or you could do a simple arugula salad with lemon vinaigrette to keep things bright. Rice absorbs any pan juices beautifully, or you could skip the starch entirely and just load up on vegetables. A crisp white wine like Sauvignon Blanc or Pinot Grigio cuts through the butter and complements the lemon without competing for attention.

• Serve with crusty bread to soak up any butter that pools on the plate.
• Add a sprinkle of grated Parmesan to the crumb topping if you want it richer.
• Lemon wedges on the side let people squeeze fresh juice over everything right before eating.

Save

This is the kind of recipe that reminds you why cooking at home matters—it's fast, it's real, and it tastes like someone cared enough to make it. Keep it in your back pocket for those nights when you want something that feels special but doesn't ask much of you.
