This is one of my favorite weeknight dinners because it comes together in under an hour and tastes restaurant quality. Cod is such a mild, delicate fish that takes beautifully to roasting, and the nutty brown butter sauce with fresh dill brings everything to life. I love adding radishes here because most people only eat them raw, but when roasted they become sweet and tender while keeping all their nutritional benefits like vitamin C and potassium. The best part is how simple it all is, just a sheet pan and one sauce to make, leaving you more time to actually enjoy your meal.

Detail level
Instructions
- 1
Preheat oven to 425°F. On a large baking sheet, toss the halved radishes with 2 tablespoons of olive oil, half the salt, and a pinch of black pepper. Spread them in a single layer cut-side down.
Tip: Radishes become sweeter and less peppery when roasted, creating a lovely caramelized exterior.
- 2
Roast the radishes for 12-15 minutes until golden brown and tender on the cut side, stirring halfway through cooking.
- 3
While radishes roast, pat the cod fillets dry with paper towels and place them on a separate section of the baking sheet or a second sheet. Brush with remaining olive oil and season with remaining salt and pepper.
Tip: Drying the fish ensures better browning and prevents sticking.
- 4
Add the cod to the oven alongside the radishes (or on a second sheet) and bake for 10-12 minutes until the fish flakes easily with a fork and is opaque throughout.
- 5
While fish and radishes cook, melt butter in a small saucepan over medium heat. Add minced garlic and sliced shallots, cooking gently for 2-3 minutes until fragrant.
- 6
Pour in the white wine and let it reduce by half, about 2 minutes. Remove from heat and stir in the lemon juice, lemon zest, and fresh dill. Season with a pinch of salt and pepper.
Tip: The brown butter should smell nutty and toasted; watch carefully to prevent burning.
- 7
Divide the roasted radishes among four plates and top each with a cod fillet.
- 8
Drizzle the brown butter and dill sauce generously over the cod and radishes. Serve immediately with crusty bread or steamed greens if desired.
Tip: Serve immediately while the fish is still warm and flaky.

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.

The seabass gets beautifully golden and flaky while the freekeh provides substantial whole grains packed with fiber and protein.
