How to Make It
Preheat oven to 425°F. Stir together harissa, olive oil, maple syrup, garlic, and salt together in a large bowl. Add carrots; toss until well coated.
Spread carrots in an even layer in a roasting pan, cover with aluminum foil, and roast at 425°F until tender, about 20 minutes. Remove foil, and cook until caramelized, 5 to 10 more minutes. Sprinkle with pistachios; serve immediately.
