Add the carrots to a sheet pan. If using petite carrots, leave whole. If using regular sized carrots, cut in half. Toss the carrots with the olive oil, honey and spices.
Bake for about 30-40 minutes, until tender, flipping halfway through baking.
While the carrots bake, finely chop the walnuts and pistachios and add them to a small bowl with the honey, cinnamon, cayenne and pinch of salt. Mix well to combine
Once the carrots are ready, plate over ricotta cheese and top with the honey nut mixture.
