This is one of my favorite weeknight dinners because it comes together in under an hour and tastes like you spent way more effort than you actually did. Cod is such a lean, delicate fish that takes beautifully to grilling, and when you pair it with a silky lemon butter sauce and tender leeks, you've got something restaurant worthy on your plate. Leeks are packed with vitamins and fiber, so you're getting something genuinely nourishing alongside pure comfort. The whole thing feels fancy but honestly, it's so simple and straightforward that even if you're new to grilling fish, you'll nail it.

Instructions
- 1
Preheat your grill to medium-high heat. Brush the grill grates with oil to prevent sticking and allow them to heat for 5 minutes.
Tip: A hot grill prevents the fish from sticking and creates beautiful char marks.
- 2
While the grill heats, prepare the leeks by brushing them with 1 tablespoon of olive oil and seasoning generously with salt and pepper on both sides.
Tip: Halving the leeks lengthwise allows them to cook evenly and creates a nice flat surface for grilling.
- 3
Season the cod fillets on both sides with salt, pepper, and lemon zest. Lightly brush with remaining olive oil.
Tip: Don't over-season; the lemon butter sauce will add plenty of flavor.
- 4
Place the leek halves on the grill cut-side down and cook for 4-5 minutes until golden brown. Flip and cook another 3-4 minutes until tender. Transfer to a warm plate.
Tip: The leeks should have some caramelization but still maintain a slight firmness.
- 5
Lay the cod fillets skin-side up on the grill and cook for 5-6 minutes without moving them. Gently flip and cook for another 3-4 minutes until the flesh is opaque and flakes easily with a fork.
Tip: Resist the urge to move the fish; letting it sit creates a nice crust.
- 6
While the fish finishes cooking, melt 3 tablespoons of butter in a small saucepan over low heat. Add minced garlic and thyme sprigs, warming until fragrant, about 2 minutes.
Tip: Keep the heat low to avoid browning the butter too quickly.
- 7
Remove the pan from heat and stir in the white wine, lemon juice, and any pan drippings from the fish. Season with a pinch of salt and pepper to taste.
Tip: The acidity from the wine and lemon brightens the rich butter sauce.
- 8
Arrange the grilled leeks on serving plates, place a cod fillet on top, and spoon the lemon butter sauce over everything. Garnish with fresh parsley and a light squeeze of additional lemon.
Tip: Serve immediately while the fish is warm and the sauce is silky.

Beergarita
My go to drink for summer gatherings is this refreshing Beergarita, and let me tell you, it's a total crowd pleaser. The combination of tequila, triple sec, fresh lime juice, and a cold Corona creates something that tastes way more complicated than it actually is. Lime juice is packed with vitamin C, which is great for your immune system, and the whole thing takes just five minutes to throw together. Best part? It's incredibly budget friendly since you're probably already stocking most of these ingredients anyway.

Tropical Quinoa
This tropical quinoa bowl has become my go to weeknight dinner because it comes together in just forty minutes and tastes like a mini vacation on a plate. Quinoa is one of my favorite ingredients since it's a complete protein with all nine essential amino acids, making it so satisfying and perfect for keeping energy levels steady. The combination of papaya, red bell pepper, and fresh cilantro brings vibrant flavors and colors, while the rice wine vinegar and orange zest add just the right brightness. Best part is the ingredient list is simple and affordable, yet feels fancy enough to impress anyone at your table.

Crispy seabass with preserved lemon yogurt
This is one of my favorite quick weeknight dinners because it comes together in just ten minutes flat. Crispy seabass with preserved lemon yogurt is that perfect balance of impressive and effortless, with tangy Greek yogurt and zingy preserved lemon creating a sauce that feels restaurant quality but tastes like home. The seabass gets beautifully golden and flaky while the freekeh provides substantial whole grains packed with fiber and protein. It's the kind of meal that makes you feel like you're treating yourself without any fuss.
