Step-by-Step Instructions 👩🍳
Step 1: Caramelize the Onions
Heat olive oil and butter in a large pot over medium heat. Add sliced onions and cook for 20–25 minutes, stirring occasionally until golden brown and sweet. Don’t rush this step—caramelization is the secret to flavor.
Step 2: Season the Base
Sprinkle in thyme, salt, and pepper. Stir well so the onions soak up the herbs and spices.
Step 3: Add the Broth
Pour in the chicken broth. Bring to a gentle simmer and let it cook for 5–7 minutes to allow flavors to meld.
Step 4: Add the Chicken
Stir in shredded chicken and let it heat through. Your soup base is now hearty and satisfying.
Step 5: Prepare the Bowls
Preheat the oven broiler. Divide soup into oven-safe bowls, top with bread cubes, and cover generously with shredded Gruyère cheese.
Step 6: Broil Until Golden
Place bowls on a baking sheet and broil for 2–3 minutes until cheese is bubbly and golden brown. Keep an eye on them to avoid burning.
Step 7: Serve Hot & Cozy
Carefully remove from the oven. Garnish with fresh herbs like parsley and serve immediately.
