This is one of my favorite weeknight dinners because it comes together in under an hour with minimal fuss. Mahi mahi is such a delicious white fish that stays tender and flaky when roasted, and it's packed with lean protein and omega 3 fatty acids that are wonderful for your heart. What I love most is that everything cooks in one pan, so cleanup is a breeze. The bright lemon butter sauce with fresh green beans creates something restaurant quality that tastes far more complicated than it actually is. Your family will think you spent hours in the kitchen, but you'll know the truth.

Instructions
- 1
Preheat your oven to 425°F. Toss the trimmed green beans with 2 tablespoons of olive oil, 2 minced garlic cloves, half the salt, and a quarter teaspoon of black pepper on a large baking sheet, spreading them in a single layer.
Tip: Arrange beans in one layer so they roast evenly rather than steam.
- 2
Place the green beans in the oven and roast for 18-20 minutes until they develop light brown spots and are tender-crisp.
- 3
While the beans roast, season both sides of the mahi mahi fillets generously with the remaining salt and black pepper.
Tip: Season the fish just before cooking to prevent it from becoming too salty.
- 4
Heat the remaining 2 tablespoons of olive oil and 1 tablespoon of butter in a large skillet over medium-high heat until shimmering.
Tip: Use a skillet large enough to fit all four fillets without crowding.
- 5
Carefully place the mahi mahi fillets skin-side up into the hot skillet and sear for 4-5 minutes until the bottom is golden, then flip and cook for another 3-4 minutes until cooked through.
Tip: Don't move the fish around in the pan; let it develop a nice crust.
- 6
Transfer the cooked fish to a warm plate. In the same skillet, reduce heat to medium and add the remaining 2 tablespoons of butter with the remaining 3 minced garlic cloves, cooking until fragrant, about 1 minute.
- 7
Pour in the white wine and lemon juice, scraping up any browned bits from the pan bottom, and simmer for 2 minutes. Stir in the fresh thyme, lemon zest, and red pepper flakes.
Tip: The wine and lemon juice create a light, flavorful sauce that pairs beautifully with the delicate fish.

Divide the roasted green beans among four plates, top each with a mahi mahi fillet, and drizzle generously with the lemon butter sauce before serving immediately.

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.
