What Ingredients You Will Need for Easy Baked Lemon Garlic Cod with Crispy Brussels Sprouts

This recipe uses straightforward, wholesome ingredients that work together to create bold flavor and satisfying textures without any fuss. Most of these are pantry staples or easy to find fresh at your market.

• Cod Fillets: About 4 pieces (6 oz / 170 g each), fresh or thawed. Firm white fish like cod is perfect for baking with a flaky texture.
• Brussels Sprouts: 1 pound (450 g), trimmed and halved. Look for firm, bright green sprouts without yellowing leaves.
• Lemon: 1 large, juiced and zested (adds brightness and tang).
• Garlic: 3 cloves, minced (fresh is best for that punchy flavor).
• Olive Oil: 3 tablespoons, good quality like Colavita or California Olive Ranch (for roasting and flavor).
• Salt & Black Pepper: To taste, preferably kosher salt for even seasoning.
• Smoked Paprika: 1 teaspoon for a subtle smoky warmth on the sprouts.
• Dried Thyme or Fresh: 1 teaspoon dried or 1 tablespoon fresh, optional, adds herby notes.
• Butter: 1 tablespoon, melted, adds richness to the cod (feel free to swap with dairy-free alternative).
• Parmesan Cheese: Optional, 2 tablespoons grated for sprinkling on sprouts before roasting (adds a savory crisp crust).

If you want to customize, you can swap cod for other flaky white fish like haddock or pollock. For a gluten-free twist, this recipe is naturally free of gluten. If garlic isn’t your thing, a pinch of onion powder can fill in nicely. And yes, frozen Brussels sprouts will work in a pinch, though fresh delivers the best crispiness.

Equipment Needed

• Baking Sheet: A rimmed baking sheet works best for roasting the cod and Brussels sprouts together without mess.
• Parchment Paper or Silicone Baking Mat: For easy cleanup and to prevent sticking.
• Mixing Bowl: To toss Brussels sprouts with oil and seasoning.
• Small Bowl or Measuring Cup: For mixing lemon garlic sauce.
• Sharp Knife: For trimming and halving Brussels sprouts and prepping fish.
• Tongs or Spatula: To turn the sprouts halfway through roasting for even crisping.

If you don’t have a rimmed baking sheet, a large oven-safe skillet will do. I personally like using a silicone mat because it saves a lot of scrubbing, but parchment paper is a great budget-friendly option. Keeping your knives sharp helps with clean cuts and safer handling, something I learned the hard way.

Preparation Method

1. Preheat your oven to 425°F (220°C). This high heat is key for getting the Brussels sprouts crispy and the cod perfectly baked.
2. Prepare the Brussels sprouts: Trim off the ends and halve them lengthwise. Toss in a mixing bowl with 2 tablespoons olive oil, smoked paprika, salt, and pepper. If you’re using Parmesan, sprinkle it in now. Spread them cut side down on your baking sheet lined with parchment.
3. Roast the Brussels sprouts: Place in the oven for about 15 minutes. Halfway through, use tongs to flip them so both sides get golden and crispy.
4. Make the lemon garlic sauce: While sprouts roast, mix lemon juice, zest, minced garlic, melted butter, 1 tablespoon olive oil, thyme, salt, and pepper in a small bowl. This sauce brightens and flavors the cod beautifully.
5. Prepare the cod: Pat the fillets dry with paper towels. Place them on the baking sheet next to the Brussels sprouts after the first 15 minutes of roasting. Brush the lemon garlic sauce generously over each fillet.
6. Bake everything together: Return the sheet to the oven and bake for another 12-15 minutes, or until the fish flakes easily with a fork and the Brussels sprouts edges are crisp and caramelized.
7. Final touches: Optional fresh lemon wedges for squeezing over at the table and a sprinkle of fresh herbs like parsley or dill for color and aroma.

Keep an eye on the fish towards the end—overcooking can dry it out. The cod should be opaque and flake apart easily when tested with a fork. If your Brussels sprouts start browning too fast, tent loosely with foil. This method balances roasting the veggies and fish in one pan, cutting down cleanup without sacrificing flavor.

Cooking Tips & Techniques

One thing I learned early on is that Brussels sprouts can be tricky—they go from perfectly crispy to burnt in a blink. That’s why I recommend tossing them cut side down; it helps them caramelize without drying out. Also, don’t overcrowd the pan. Give them space to crisp instead of steam.

For the cod, drying the fillets before seasoning is a small but game-changing step. Moisture on the surface hinders browning and causes sogginess. Brushing the lemon garlic sauce right before baking locks in moisture and flavor but avoid marinating for hours — fresh is best here.

Timing is everything. Start the Brussels sprouts first because they take longer to roast. Adding the fish halfway through ensures both finish together, and you won’t have a cold or overcooked component on your plate.

When multitasking, prep the lemon garlic sauce early so it’s ready when the sprouts come out. Checking the fish gently with a fork at the 12-minute mark helps avoid dry, tough results. If you want to experiment, sprinkling a little chili flakes into the sauce adds a nice kick.

Variations & Adaptations

• Herb Swaps: Instead of thyme, try fresh dill or rosemary for a different herbal note that complements the lemon and garlic.
• Spice it Up: Add red pepper flakes or a dash of cayenne to the lemon garlic marinade for a spicy twist.
• Different Veggies: Swap Brussels sprouts for asparagus or green beans if you want a lighter, quicker roasting side.
• Low-Carb Option: Serve the cod and sprouts over cauliflower rice for a filling but lighter meal.
• Dairy-Free: Use olive oil instead of butter in the lemon garlic sauce to keep it fully dairy-free without sacrificing flavor.

One personal favorite variation includes topping the Brussels sprouts with a handful of toasted pine nuts right after roasting for a nutty crunch. Another time, I lightly dusted the cod with a bit of cornstarch before baking to get an almost crispy crust — that one’s a keeper for sure.

Serving & Storage Suggestions

This dish is best served fresh and warm, straight from the oven to your plate. A squeeze of fresh lemon over the top before eating brightens every bite. I like to plate the cod alongside the crispy Brussels sprouts with a simple green salad or some roasted baby potatoes, like the garlic mashed make-ahead mashed potatoes for a more hearty dinner.

For storage, keep leftovers in an airtight container in the refrigerator for up to 2 days. Reheat the cod gently in a low oven (around 300°F / 150°C) to avoid drying it out, and pop the Brussels sprouts under the broiler for a minute or two to re-crisp.

Flavors meld nicely after a day, especially the lemon garlic notes, making this a great meal prep option. Just be mindful that Brussels sprouts may soften a bit in the fridge, so reheating with some extra olive oil can bring back that roasted crispness.
