Tips for the Best Soup

• Take your time caramelizing onions: Don’t rush — the deep flavor develops slowly.

• Use bone-in short ribs: Bones enrich the broth with collagen and depth.

• Toast bread well: Prevents it from becoming soggy under the cheese.

• Use high-quality cheese: Gruyère is traditional, but Comté is an excellent substitute.

• Make ahead: Soup base tastes even better the next day.

Variations to Try

• Mushroom addition: Add sautéed mushrooms for extra umami.

• Different proteins: Swap short ribs with chuck roast or even lamb shanks.

• Wine swap: Use white wine for a lighter broth.

• Cheese twist: Mix Gruyère with sharp cheddar for a bolder flavor.

• Low-carb option: Skip the bread and top with just cheese.

Perfect Pairings

Side Dishes

• Simple green salad – Lightens the richness.

• Roasted vegetables – Carrots, Brussels sprouts, or asparagus.

• Herbed rice or polenta – As a base for extra comfort.

Drinks

Storing and Reheating
