Instructions
- 1
Preheat your grill to medium-high heat and oil the grates well to prevent sticking.
Tip: If using a gas grill, preheat for 10 minutes; for charcoal, wait until coals are evenly heated.
- 2
Boil the cubed turnips in salted water for 12-15 minutes until fork-tender. Drain and set aside.
Tip: Cut the turnips into uniform pieces so they cook evenly.
- 3
In a small skillet, melt 2 tablespoons of butter over medium heat. Add the sliced shallot and minced garlic, sautéing for 2 minutes until fragrant but not browned.
Tip: Keep the heat moderate to avoid burning the garlic, which will make it bitter.
- 4
Return the cooked turnips to the skillet with the shallot-garlic mixture. Pour in the vegetable broth and simmer for 3 minutes to infuse flavors.
Tip: The broth helps create a creamier texture for the puree.
- 5
Transfer the turnip mixture to a blender or use an immersion blender to puree until smooth. Season with half the salt and pepper.
Tip: For a chunkier texture, mash by hand with a potato masher instead of blending.
- 6
Pat the cod fillets dry with paper towels and brush both sides with olive oil. Season the skin side with remaining salt and pepper.
Tip: Drying the fish ensures a better sear and prevents the skin from sticking to the grill.
- 7
Place cod fillets skin-side down on the grill. Place a thyme sprig and a lemon half on each fillet. Grill for 4-5 minutes without moving, until the skin is crispy and releases easily.
Tip: Resist the urge to flip—the longer the skin stays on the grill, the crispier it becomes.
- 8
Carefully flip the fillets and grill for another 3-4 minutes until the flesh is opaque and flakes easily with a fork.
Tip: The internal temperature should reach 145°F for perfectly cooked cod.
- 9
In a small saucepan, melt the remaining 2 tablespoons of butter over medium heat until it turns golden brown and smells nutty, about 3-4 minutes. Add the sage leaves and fry for 30 seconds until crispy.
Tip: Watch the brown butter carefully—it can burn quickly once it begins to darken.
- 10
Spoon the turnip puree onto each plate. Top with a grilled cod fillet skin-side up, and drizzle with the brown butter and crispy sage. Serve immediately.
Tip: Serve with a squeeze of fresh lemon juice for brightness.

My go to drink for summer gatherings is this refreshing Beergarita, and let me tell you, it's a total crowd pleaser.

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.

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.

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