Step‑by‑Step Instructions for French Lentil Soup
Step 1: Soak Cashews
Begin by placing raw cashews in a bowl and covering them with water. Allow them to soak for 1-2 hours, or opt for a quick soak method by pouring boiling water over them for 30-60 minutes. After soaking, drain and rinse the cashews to ensure a smooth, creamy base for your French Lentil Soup.
Step 2: Blend Cashew Cream
In a blender, combine the soaked cashews with half a cup of water. Blend on high until the mixture is smooth and creamy with no lumps remaining. This cashew cream will add a rich texture to your soup, so set it aside while you prepare the flavorful base.
Step 3: Sauté Vegetables
In a large Dutch oven, heat 1 tablespoon of extra-virgin olive oil over medium heat. Add chopped onions and minced garlic, sautéing for 4-6 minutes until they become translucent and fragrant. This step builds the aromatic foundation of your French Lentil Soup, filling your kitchen with a delightful warmth.
Step 4: Add Carrots and Celery
Stir in the diced carrots and chopped celery into the pot, cooking for an additional 3-4 minutes until they begin to soften. The vibrant colors of the vegetables will brighten up the dish as they contribute both sweetness and texture to your hearty soup.
Step 5: Add Spices
Sprinkle in ground cumin, dried thyme, and ground turmeric, stirring continuously for about 1 minute until the spices become fragrant. This is where your French Lentil Soup truly starts to come alive with warm, earthy flavors that will enrich the overall experience.
Step 6: Simmer Soup
Pour in diced tomatoes and their juices, along with rinsed French green lentils and veggie broth. Add as much water as you need to cover the ingredients. Bring the mixture to a boil, then lower the heat to a gentle simmer. Cook uncovered for 30-35 minutes, stirring occasionally, until the lentils are tender but still hold their shape.
Step 7: Finish Soup
Once the lentils are cooked to perfection, stir in the prepared cashew cream and chopped Swiss chard. Season the soup with salt, freshly ground black pepper, and a splash of white wine vinegar to taste. Allow it to cook for an additional 2-3 minutes, until the greens are wilted and vibrant.
Step 8: Serve
Your creamy French Lentil Soup is ready to be enjoyed! Ladle the soothing soup into bowls and garnish as desired. Pair it with crusty bread or a simple salad for a complete meal that’s not only comforting but also bursting with flavors and nutrients.

French Lentil Soup Recipe FAQs
How do I select the best lentils for my soup?
Absolutely! When choosing French green lentils, look for ones that are firm and uniform in color. Avoid any that have dark spots or a faded appearance—these could indicate age or spoilage. Fresh lentils will hold their shape beautifully during cooking, creating that ideal texture.
How should I store my French lentil soup?
Very simply! Store your soup in an airtight container in the fridge for up to 5 days. To keep it fresher for longer, you can also freeze it. Just pour the cooled soup into freezer-safe containers, leaving some room at the top for expansion. It will be good for 1-2 months; just remember to label the containers!
Can I freeze French lentil soup?
Absolutely! To freeze, let the soup cool completely and then transfer it into freezer-friendly containers or resealable bags. For easier portioning, consider freezing it in individual servings. When ready to enjoy, thaw overnight in the fridge or use the defrost setting on your microwave.
What should I do if my soup is too thick?
No worries! If you find your French lentil soup too thick after cooking, simply add a bit of vegetable broth or water a little at a time while stirring. Heat on low until mixed well. This keeps the flavors intact while adjusting the soup to your preferred consistency.
Can my pets eat any ingredients from the soup?
It’s important to be cautious! While lentils and vegetables like carrots and celery are often safe for pets, keep in mind that garlic and onion can be toxic to many pets, especially dogs. If you’re sharing leftovers, ensure they are free from those ingredients for the safety of your furry friends.
Are there any allergens to be aware of in this recipe?
For sure! This recipe uses cashews, which can be a common allergen, so it’s important to substitute with sunflower seeds if you need a nut-free option. Additionally, always check your vegetable broth for allergens if you’re serving anyone with dietary restrictions since some brands may contain gluten or other allergens.
