Step-by-step Preparation of Creamy French Onion and Mushroom Soup
Making creamy French onion and mushroom soup at home is not only satisfying, but it also fills your kitchen with an irresistible aroma that’s perfect for any chilly evening. Let’s dive into the steps to create this rich and decadent soup.
Sauté the onions and honey
Begin by melting 6 tablespoons of salted butter in a large Dutch oven over medium-high heat. Once the butter is bubbling, add in 4 medium yellow onions, thinly sliced, along with 1 teaspoon of honey. The honey helps to enhance the natural sweetness of the onions. Stir occasionally for about 10 minutes until they become soft. This step is crucial, as the onions should be tender but not browned yet.
Caramelize and add the mushrooms
Next, it’s time to deepen those flavors! Continue to cook the onions, stirring occasionally, for another 10-15 minutes until they caramelize to a golden brown. Now, add 3 cloves of minced garlic and 2 cups of sliced cremini or wild mushrooms to the pot, along with 2 tablespoons of fresh thyme leaves and 2 tablespoons of chopped fresh sage. Don’t forget to season with salt and pepper; these will add to the soup's depth. Sauté everything together for about 3-4 minutes until the mushrooms are tender.
Incorporate the broth and herbs
Now comes the important part: adding the liquids. Pour in 6-8 cups of low-sodium chicken or vegetable broth and toss in 2 bay leaves and 2 teaspoons of Worcestershire sauce for that extra umami kick. Bring the mixture to a simmer and let it cook for about 10 minutes. This allows the flavors to meld beautifully.
Stir in the cream
After the broth has simmered, it’s time to introduce the rich creaminess. Remove the bay leaves from your soup and stir in ½ cup of heavy cream. Allow it to simmer for an additional 5-10 minutes, and season with salt and pepper to taste. At this point, take a moment to savor that delicious aroma wafting through your kitchen.
Prepare and toast the bread
While the soup is bubbling away, preheat your oven to 400°F. Slice 6 pieces of French bread and arrange them on a baking sheet. Toast them in the oven for about 10-15 minutes until they’re very dry but not burnt. This crunchy topping is crucial for textural contrast in your soup.
Assemble and broil the soup
For the grand finale, ladle your delicious soup into oven-safe bowls. Add a toast slice on top of each bowl and generously sprinkle with 2 cups of shredded Gruyère cheese. Place the bowls on a baking sheet and broil them in the oven for about 3-5 minutes, or until bubbly and golden brown. Finally, sprinkle with a bit of fresh thyme for a delightful garnish before serving.
And there you have it! A cozy bowl of creamy French onion and mushroom soup that’s sure to impress everyone. Enjoy!
