Preheat your oven to 450F.
Place a large baking sheet into the oven while it heats up.
With a sharp knife, cut your carrots into 4 inch chunks. Place in a bowl and season with 1 tbsp of olive oil and 1 tsp of kosher salt.
Once your oven and pan is heated, add your carrots to the hot pan and roast for 20-25 min. Once tender and roasted, pull and set aside.
While your carrots are roasting, brown ⅓ cup of butter. Once browned add ½ cup of honey and ½ a juiced orange. Mix well. Make sure you let your butter cool before you add your honey and orange juice, it might bubble up!
Drizzle your brown butter-honey onto the carrots, mix around and bake for another 5 min.
Pull from the oven, place in your serving dish and sprinkle on 1 cup of chopped pistachio.
