Ingredients You’ll Need

For the Roasted Brussels Sprouts

• Brussels sprouts: One pound, trimmed and halved to ensure maximum surface area for browning.
• Olive oil: Use a high-quality extra virgin olive oil for the best flavor.
• Salt and Black pepper: To bring out the natural nuttiness of the sprouts.
• Garlic powder (Optional): Adds a layer of savory depth.
• Red pepper flakes (Optional): For a subtle Mediterranean heat.

Roasting Brussels sprouts is a game-changer. Unlike steaming, roasting at high heat caramelizes the natural sugars in the vegetable, turning a polarizing green into a crispy, sweet, and savory side dish that even skeptics will enjoy.

For the Lemon Garlic Butter Cod

• Cod fillets: Four 6-ounce fillets. Look for thick, firm pieces.
• Butter & Olive oil: We use a blend for searing—butter for flavor and olive oil for a higher smoke point.
• Garlic: Freshly minced is non-negotiable here.
• Lemon juice & zest: Provides the essential “zing” that defines Mediterranean seafood.
• Heavy cream: This creates the “velvety” finish seen in the recipe photo.
• Paprika: Adds a beautiful golden color and a hint of smokiness.
• Salt and pepper: To season the fish thoroughly.

In Mediterranean cooking, the lemon garlic butter sauce serves as a bridge. It moistens the lean fish while adding enough fat to keep you satisfied, making it a staple technique for everything from baked cod recipe to shrimp and scallops.

How to Make Lemon Garlic Butter Cod with Roasted Brussels Sprouts

Step 1: Roast the Brussels Sprouts

Preheat your oven to 400°F (200°C). After trimming the woody ends and halving the sprouts, toss them directly on a sheet pan with olive oil, salt, pepper, and your optional spices. Spread them out in a single layer—crowding the pan will cause them to steam rather than roast. Bake for 20–25 minutes until the edges are charred and crispy.

Step 2: Prepare the Cod Fillets

While the sprouts are in the oven, take your cod fillets and pat them very dry with paper towels. This is the secret to a good sear. If the fish is damp, it will boil in the pan. Once dry, season both sides generously with salt, pepper, and a dusting of paprika.

Step 3: Sear the Cod

Heat a large skillet over medium-high heat with a tablespoon each of olive oil and butter. Once the butter foams, place the cod fillets in the pan. Cook for 3–4 minutes per side. The cod is done when the internal temperature reaches 145°F (63°C) and the flesh flakes easily with a fork. Remove the fish and set aside on a plate.

Step 4: Make the Lemon Garlic Cream Sauce

In the same skillet (don’t wash it!), reduce heat to medium. Add the remaining butter and the minced garlic. Sauté for about 30–60 seconds until fragrant but not brown. Pour in the heavy cream, lemon juice, and zest. Simmer for 2–3 minutes, stirring constantly, until the sauce thickens slightly into a luxurious glaze.

Step 5: Assemble the Dish

Place a generous portion of roasted Brussels sprouts into a shallow bowl or plate. Nestling the seared cod on top, spoon the warm lemon garlic butter sauce over the fish and the sprouts, allowing the sauce to pool slightly at the bottom.

Tips for Perfect Cod Every Time

• Fresh vs. Frozen: Use fresh cod if possible. If using frozen, thaw it completely in the fridge and pat it extremely dry.
• The Sizzle Factor: Ensure your pan is hot before adding the fish to get that beautiful golden crust.
• Don’t Overcook: Cod can go from perfect to rubbery in a minute. Watch for the flakes to just begin to separate.
• Zest First: Always zest your lemon before juicing it. The zest contains the essential oils that provide the most “lemon” flavor without the extra acid.

What to Serve with Cod and Brussels Sprouts

While this dish is a complete meal on its own, you can round it out with these Mediterranean favorites:

• Mediterranean quinoa: For a nutty, protein-packed grain.
• Lemon rice: To soak up every drop of that garlic cream sauce.
• Garlic roasted potatoes: If you want a heartier, starch-heavy meal.
• Simple cucumber salad: To provide a cool, crisp contrast to the warm fish.
• Warm pita bread: Perfect for dipping into the leftover sauce.

Variations of This Recipe

Sheet Pan Version

If you prefer a hands-off approach, you can make this a one pan cod dinner. Roast the sprouts for 15 minutes, then nestle the seasoned cod fillets onto the same pan and bake for another 10–12 minutes. Pour the sauce (made separately) over the top before serving.

Dairy-Free Version

To keep this Mediterranean fish recipe dairy-free, replace the butter with more olive oil or a vegan butter substitute. Instead of heavy cream, use full-fat coconut cream or simply omit the cream for a lighter “Agliata” style sauce.

Spicy Version

Add a teaspoon of crushed red pepper flakes to the roasting sprouts and a pinch of cayenne pepper to the cod seasoning for a spicy Mediterranean kick.

Storage and Reheating Tips

• Store: Keep leftovers in an airtight container in the refrigerator for up to 3 days.
• Reheat: Avoid the microwave, which can make the cod rubbery. Instead, reheat gently in a skillet over low heat with a splash of water or broth to loosen the sauce.

Health Benefits of Cod and Brussels Sprouts

This meal is a nutritional powerhouse. Cod is an excellent source of lean protein and heart-healthy omega-3 fatty acids, which are essential for brain health. It’s also rich in Vitamin B12. Brussels sprouts provide a massive hit of fiber, Vitamin C, and Vitamin K, acting as a powerful antioxidant. Together, they represent the core of the Mediterranean lifestyle: simple, unprocessed, and nutrient-dense.
