A cozy and classic French onion soup featuring sweet caramelized onions and bubbly Gruyere toast, perfect for comforting meals any time.
Cook onions low and slow to avoid burning and develop deep caramelized flavor. Stir gently and regularly. Watch the broiler carefully to prevent cheese from burning. Use day-old bread for best texture. For dairy-free, use vegan butter and plant-based cheese. For vegetarian, substitute beef broth with vegetable broth.
