French Onion Soup- Catering

This is French onion soup scaled up for a crowd. Nearly five pounds of onions simmer in shortening until light brown, then cook in water and beef stock to build a rich, deeply savory broth. The catering-size batch makes it practical for parties, buffets, or meal prep.

Browning the onions to light golden (not dark caramel) keeps the soup approachable. A lighter color means a sweeter, milder onion flavor compared to the deeply caramelized versions that can taste almost bitter.

Toasted bread cut into decorative shapes goes in each bowl before the hot soup is ladled over. The bread softens on the bottom where it meets the broth while staying crispy on top. A generous sprinkle of grated Parmesan finishes each serving.

The recipe suggests veal stock if available. Veal stock has more natural gelatin than beef stock and gives the broth a silkier body.

Chef Tips

• Cook the onions covered after adding water. The steam helps break them down faster and distributes heat evenly.
• Use a good, dark beef stock for the richest flavor. Bouillon cubes taste thin at this volume.
• Cut the toast into rounds or triangles that fit neatly in the soup bowl. Oversized bread gets soggy and falls apart.
• For a more traditional presentation, top with Gruyère instead of Parmesan and broil until bubbly.

Variations

• Classic gratinée: Use ovenproof bowls, top with Gruyère, and broil for a melted cheese cap.
• Half batch: Cut all ingredients in half for a family-sized pot of about 12 servings.
