Lentil Soup Ingredients
Unlock the savory secrets of this hearty dish!
For the Soup Base
• Extra-virgin olive oil – Adds richness and depth; try avocado oil for a different flavor profile.
• Onion (1 medium, chopped) – Base flavor for the soup; you can omit for a milder taste.
• Carrots (4 medium, chopped) – Provides sweetness and color; parsnips or sweet potatoes work well as replacements.
• Celery (2 stalks, chopped) – Adds a lovely crunch; diced fennel can be used for an aromatic twist.
• Garlic (4 cloves, grated) – Infuses the soup with aromatic depth; fresh is preferred but garlic powder can be used in a pinch.
For the Lentil Mixture
• Green lentils (¾ cup, rinsed) – A powerhouse of protein; avoid red lentils since they become mushy.
• Fire-roasted diced tomatoes (1 can, 14 ounces) – Adds a smoky sweetness; regular diced tomatoes can be used for a less pronounced flavor.
• Ground cumin (heaping ½ teaspoon) – Enhances earthiness; coriander is a good substitute for a different spice profile.
• Sea salt (1½ teaspoons) – Essential for flavor enhancement; adjust based on your taste preference.
• Black pepper – Adds mild heat; opt for freshly ground for maximum impact.
For the Finishing Touches
• Kale (6 small or 3 large leaves, chopped) – Nutritional powerhouse; swap for spinach or Swiss chard if desired.
• Fresh thyme sprigs (12, bundled) – Imparts fragrant herbal notes; use 1 teaspoon of dried thyme if fresh isn't available.
• White wine vinegar (2 tablespoons) – Adds brightness; lemon juice can be a great substitute for a zesty kick.
• Vegetable broth (6 cups) – Enhances flavor and keeps the soup light; chicken broth can be used for non-vegetarian options.
• Fresh parsley (½ cup, chopped) – For garnish and added freshness; optional if you prefer a simpler presentation.
• Red pepper flakes – Optional for a touch of heat; adjust according to your preference.
• Grated Parmesan cheese – Optional topping for a richer flavor; omit for a fully vegan soup.
This nourishing Lentil Soup is ready for you to create a warm, comforting meal that you'll love!
Step‑by‑Step Instructions for Hearty Vegan Lentil Soup with Kale
Step 1: Heat the Oil
In a large pot, pour in 2 tablespoons of extra-virgin olive oil and heat over medium heat. Allow the oil to shimmer but not smoke, indicating it's ready. This will be the base for your Hearty Vegan Lentil Soup, so let the richness begin to build!
Step 2: Sauté the Vegetables
Add 1 medium chopped onion, 4 chopped carrots, 2 chopped celery stalks, chopped kale stems, ½ teaspoon ground cumin, 1½ teaspoons sea salt, and freshly ground black pepper to the hot oil. Stir well, cooking for about 8 minutes until the vegetables are softened and fragrant, creating a beautiful medley of colors.
Step 3: Add the Aromatics
Stir in 4 grated garlic cloves, cooking for an additional 1-2 minutes until fragrant. You’ll know it’s time to move on when the aroma fills your kitchen, enticing everyone to gather around for this delicious Hearty Vegan Lentil Soup.
Step 4: Combine the Main Ingredients
Pour in 1 can of fire-roasted diced tomatoes (14 ounces), ¾ cup rinsed green lentils, 2 tablespoons white wine vinegar, and the bundled fresh thyme sprigs. Follow with 6 cups of vegetable broth, stirring everything together. This combination will bring depth and flavor, so bring the mixture to a gentle simmer.
Step 5: Simmer for the Perfect Texture
Cover the pot and let the soup simmer for 25-30 minutes over low heat. Keep an eye on it; the lentils should become tender but still maintain their shape. Stir occasionally, enjoying the comforting scent that fills your home.
Step 6: Incorporate the Greens
After the lentils are cooked, add in the chopped leaves (6 small or 3 large) of kale. Cook for another 5 minutes until the kale is wilted and vibrant, enhancing the colorful look of your Hearty Vegan Lentil Soup.
Step 7: Final Touches
Remove the thyme bundle from the pot and taste the soup, adjusting the seasoning as needed. If you desire, serve your soup hot, garnished with chopped fresh parsley, a sprinkle of red pepper flakes for heat, and optional grated Parmesan cheese for added richness. A slice of crusty bread on the side is perfect for dipping!
