Key Ingredients
Mushrooms (12 large fresh mushrooms)
Fresh mushrooms bring a meaty texture and earthy flavor to any dish, making them an indispensable ingredient here. I love using white or cremini mushrooms because they add depth without overpowering other ingredients.
Onions (2 large yellow onions, thinly sliced)
Onions are the star of this soup, slowly cooked until they caramelize into a sweet, golden-brown delight that mingles beautifully with the umami-rich mushrooms. A good tip is to slice your onions as thinly and evenly as possible for consistent cooking.

Garlic (3 cloves garlic, minced)
Garlic adds a subtle yet essential layer of flavor. Mincing it finely ensures its essence infuses throughout the soup without overpowering the delicate balance created by the onions and mushrooms.
Butter and Olive Oil
A combination of 2 tablespoons butter and 1 tablespoon olive oil helps to create a rich, flavorful base for the soup. The butter adds richness while the olive oil enhances the overall texture.
