This is one of my favorite weeknight dinners because it comes together in just 40 minutes and feels fancy enough for company. Tilapia is such a mild, delicate fish that pairs beautifully with roasted parsnips and a fragrant herb butter. I love that parsnips are packed with fiber and vitamins, making this dish as nourishing as it is delicious. The best part? Everything roasts on one pan, which means minimal cleanup and maximum flavor. Fresh thyme and parsley brighten up the whole meal, while a splash of white wine adds elegance without any fuss.

Instructions
- 1
Preheat your oven to 400°F (200°C). Toss the parsnip batons with 2 tablespoons of olive oil, half the salt, and a quarter teaspoon of pepper on a large baking sheet. Spread in a single layer and roast for 15 minutes until they begin to soften and develop golden edges.
Tip: Cut parsnips to uniform size so they cook evenly
- 2
While parsnips roast, prepare the herb butter by mixing softened butter with chopped parsley, thyme, minced garlic, lemon zest, and remaining salt and pepper in a small bowl.
Tip: Make herb butter ahead of time and refrigerate until needed
- 3
Pat the tilapia fillets dry with paper towels and brush both sides with the remaining 1 tablespoon of olive oil. Season with salt and pepper.
Tip: Dry fish ensures better browning and prevents sticking
- 4
Remove the baking sheet from the oven and nestle the seasoned tilapia fillets among the partially cooked parsnips. Drizzle the wine around the pan if using.
Tip: Arrange fish skin-side up for better presentation
- 5
Return the baking sheet to the oven and roast for 10-12 minutes until the tilapia is opaque and flakes easily with a fork.
Tip: Don't overcook tilapia as it becomes dry; check at the 10-minute mark
- 6
Remove from the oven and immediately top each tilapia fillet with a generous dollop of herb butter, allowing it to melt over the warm fish. Squeeze fresh lemon juice over everything.
Tip: The residual heat will melt the butter perfectly without further cooking
