Aligot is a comforting dish of cheesy whipped potatoes that originated in the L'Aubrac region of central France. Traditional aligot is made with Tomme d'Auvergne, a creamy young cheese that's nutty and stretchy when melted. We opted for a more accessible combination of shredded Gruyere and fresh mozzarella, resulting in similar texture and flavor. We also added roasted garlic to our version. Top with finely chopped chives and serve right off the stove for a hearty side dish.
