Cook Notes

Elevate your French Pearl Onion Soup to perfection with these expert tips:

  1. Peeling Pearl Onions: Blanch the pearl onions in boiling water for a minute, then transfer them to an ice bath. This will make peeling them a breeze.
  2. Choosing the Right Wine: Opt for a dry white wine like Sauvignon Blanc or Pinot Grigio to complement the savory richness of the broth.
  3. Homemade Beef Broth: For an extra layer of flavor, consider making your own beef broth using a combination of beef bones, vegetables, and herbs.
  4. Cheese Selection: While Gruyère is a classic choice, you can experiment with other melting cheeses like Swiss or Emmental for a unique twist.


Customize your French Pearl Onion Soup experience with these delightful variations:

Herb-Infused Broth:

Add a bouquet garni of fresh herbs, such as thyme, rosemary, and parsley, to the simmering broth for an aromatic infusion.

Caramelized Onion Topping:

Before serving, caramelize a handful of additional pearl onions and use them as a topping along with the Gruyère-covered croutons.

Vegetarian Twist:

Replace beef broth with vegetable broth and enhance the soup’s umami with a dash of soy sauce or Worcestershire sauce.

Keto Versions
