Pressure Cooker French Onion Soup

Introduction

What is French Onion Soup?

Pressure Cooker French Onion Soup is a traditional dish that features caramelized onions, savory broth, and a layer of melted cheese atop crusty bread. It’s known for its rich, comforting flavors and luxurious texture, making it a staple in classic French cuisine.

The History of French Onion Soup and Its Place in Classic French Cuisine

Dating back to ancient Roman times, French onion soup became a culinary icon in France during the 18th century. Initially considered a humble dish due to its inexpensive ingredients, it rose to fame as chefs elevated it with high-quality broth, cheese, and artisan bread.
