To make the carrots: Preheat the oven to 425 degrees with a rack in the center. Pour 2 tablespoons oil into an ovenproof pan large enough to hold the carrots in a single layer (or do this step in 2 pans). Let the oil come to barely smoking over high heat, then add the carrots and stir to coat them in the oil. Sprinkle with 1 teaspoon salt. Cook, turning occasionally, until the carrots are browning in spots — about 6 to 8 minutes, but not yet cooked through. Once they're nicely browned in spots, place the whole pan in the hot oven and roast, stirring occasionally, until carrots are tender and cooked through, about 8 to 12 minutes. Remove from oven and let cool slightly.
Toss the cooked carrots very gently, as they'll be soft, with the 3 tablespoons prepared pesto, using more or less based on your taste. Transfer the coated carrots to a platter, and top with the burrata. (You may want to halve or quarter your burrata, depending on its size.) Add a few more dollops of pesto to the carrots, and sprinkle each piece of burrata with a bit of flaky salt.
Dress the reserved handful of carrot top sprigs and basil with a squeeze of lemon, a drizzle of olive oil and a small pinch of salt. Top the carrots and burrata with the carrot tops and basil.
Note: This is the salad to make when you have a bunch of radish and beet tops or any other greens and any other vegetables you need to use up. From the Detroit Free Press.
