How to Make Creamy French Onion and Mushroom Soup

Follow these simple steps to prepare this delicious dish:

Step 1: Caramelize the Onions

Start by slicing your onions thinly. In a large pot over medium heat, melt your butter. Add the sliced onions and cook them slowly until they turn golden brown, stirring occasionally. This should take about 20-25 minutes—be patient!

Step 2: Sauté the Mushrooms

Once your onions are perfectly caramelized, throw in the sliced mushrooms along with minced garlic. Cook until the mushrooms release their moisture and become tender—around another 5-7 minutes will do nicely.

Step 3: Add Broth and Season

Pour in your broth of choice (vegetable or chicken), add thyme leaves, salt, and pepper. Give everything a good stir and let it simmer for about 15 minutes so those flavors can mingle.

Step 4: Blend It Up

This step is optional but highly recommended for extra creaminess! Use an immersion blender directly in the pot to puree some of the soup for a smoother texture while keeping some chunks for added bite.

Step 5: Finish with Cream

Stir in heavy cream slowly while heating on low until warmed through. Taste again for seasoning adjustments—it’s all about making it perfect!

Step 6: Serve It Up

Ladle into bowls and garnish with fresh herbs if desired. Pair it with crusty bread for dunking joy—the ultimate comfort meal experience!

Serve hot, savoring each creamy spoonful as you slip into relaxation mode—because who doesn’t love feeling pampered at home?

Perfecting the Cooking Process

Start by caramelizing the onions until golden brown for that sweet flavor. While they cook, sauté the mushrooms separately to enhance their earthiness. Combine both, add garlic, then stir in broth and cream for delicious results.

Add Your Touch

Feel free to swap in different mushrooms like shiitake or portobello for varied flavors. You can also sprinkle in some thyme or nutmeg for an aromatic twist. Want it cheesy? Top with gruyere before broiling.

Storing & Reheating

Store any leftovers in an airtight container in the fridge for up to three days. Reheat gently on the stove over low heat, adding a splash of broth if needed to maintain creaminess.
