Preheat the oven to 425°F and line a sheet pan with parchment paper.
Whisk the honey, minced garlic, 2 tablespoons of sherry vinegar, and 3 tablespoons of olive oil together in a large bowl.
¼ cup honey, 2 cloves garlic, 3 tablespoons sherry vinegar, 5 tablespoons extra virgin olive oil
Add the carrots, a generous pinch of kosher salt, a few cracks of pepper, and 1 teaspoon of the thyme, then toss until evenly coated.
2 pounds carrots, kosher salt, freshly cracked black pepper, 2 teaspoons fresh thyme leaves
Spread the carrots and garlic in a single layer on the prepared sheet pan, arranging the carrots cut-side down. Pour any remaining glaze from the bowl over the top.
Roast until the bottoms are caramelized, about 20 minutes. Turn the carrots and toss them in the glaze, then lower the oven to 400°F and continue roasting until tender and caramelized around the edges, about 15-20 minutes longer, depending on their thickness.
While the carrots roast, make the whipped ricotta. Add the ricotta, remaining 2 tablespoons of olive oil, lemon zest, lemon juice, and a pinch of salt to a food processor.
15 ounce container whole-milk ricotta, zest of 1 lemon, 1 tablespoon fresh lemon juice
Process until light and creamy, scraping down the sides as needed, about 1-2 minutes. Taste and adjust the salt and lemon as needed.
Remove the carrots from the oven and drizzle with the remaining 1 tablespoon of sherry vinegar. Toss gently, then set aside to cool slightly.
Add the hazelnuts to a dry skillet over medium heat. Toss them around for a minute or two until they just barely start to take on a slightly darker color. Add the butter and continue cooking until it melts, foams, and the milk solids turn golden brown along with the hazelnuts.
½ cup hazelnuts, 4 tablespoons unsalted butter
Remove from the heat, then add the remaining 1 teaspoon of thyme leaves, and toss to combine. Be careful, as they may pop and spatter as they hit the hot fat.
Spread the whipped ricotta generously over a serving platter. Arrange the warm roasted carrots on top, then spoon the brown butter hazelnuts over the carrots. Finish with flaky salt, black pepper, and additional thyme.
