Turn the KitchenAid Multi-Cooker
on Sear. Add the oil and once the Multi-Cooker is preheated, add the onion, butternut squash, apples, celery roots and garlic. Sear and stir (by hand or with the KitchenAid Multicooker Stir Tower) until soft and slightly brown, about 15 minutes. Then add the vegetable broth until it reaches the max fill line. Stir in the herbes de provence, 1 1/2 teaspoons salt, and 1/2 teaspoon pepper.
