• I take pride in making this dish completely plant-based and wholesome.

My Inspiration Behind This Lentil Soup

• Growing up, lentil soup was a weekly staple in my family’s kitchen. I learned early on that it’s about patience—lettils need time to soften and develop flavor. Now, I find comfort in its slow simmer, knowing each ingredient has a moment to shine.
• It’s a humble dish, but one that’s adaptable to whatever’s in the fridge. I often toss in a handful of greens or a splash of coconut milk for richness, making it my own. It’s a reminder that simple ingredients, treated with care, can turn into something truly satisfying.

The Rich History and Fun Facts of Lentil Soup

• Lentils have been a staple in Middle Eastern and Mediterranean diets for thousands of years.
• This dish is a modern twist on traditional hearty pulses, adapted for vegan and plant-based eating.
• The name ‘lentil’ comes from Latin ‘lens,’ referring to the shape of the legume.
• In some cultures, lentil soup is believed to bring good luck and prosperity when eaten on New Year’s Day.

Ingredient Notes and Tweak Tips

• Lentils: I prefer green or brown—they hold shape but soften nicely. Rinse well to remove dust.
• Onions: They create a sweet base when sautéed. If you’re out, a dash of onion powder works.
• Carrots: Add sweetness and texture. Use parsnips or sweet potatoes as a swap for a different flavor.
• Garlic: It’s the aromatherapy of the dish. Use fresh for the best punch; garlic powder can substitute but loses aroma.
• Cumin: Its earthy, smoky scent is key. Try smoked paprika for a similar depth if you’re out.
• Tomatoes: They add acidity and brightness. Canned diced work, or fresh in season.
• Vegetable broth: The backbone of flavor. Water can be a substitute, but you’ll need more seasoning.

Spotlight on Lentils and Garlic

Lentils:

• They soften beautifully, releasing a nutty aroma. Keep an eye to prevent over-mushing.
• They tend to get mushy if overcooked—timing is everything.
• They absorb flavors and can be a bit gritty if not rinsed properly.

Garlic:

• It’s the fragrant heart of this soup. It transforms from raw sharpness to sweet, mellow goodness when sautéed.
• During cooking, it should turn golden, releasing a warm, inviting smell.
• Avoid burning garlic—the bitter taste will ruin your soup.

Smart Substitutions for Common Ingredients

• Broth: Water or mushroom stock can step in, though flavor will diminish slightly.
• Spices: Swap cumin for coriander or turmeric for different warm notes.
• Vegetables: Swap carrots for sweet potatoes or parsnips for a different sweetness.
• Herbs: Fresh cilantro or basil can replace parsley for varied freshness.
• Acid: Lemon juice or vinegar can replace or complement the lemon squeeze at the end.

Equipment & Tools

• Large soup pot: To cook the soup evenly
• Cutting board and knives: Chopping vegetables and herbs
• Wooden spoon or spatula: Stirring ingredients without damaging non-stick surfaces
• Immersion blender (optional): Pureeing for creaminess or texture adjustments
• Measuring spoons and cups: Accurate ingredient measurement

How to Make Vegan Lentil Soup: A Step-by-Step Guide

1. Heat a large pot over medium heat, add a splash of oil, and sauté chopped onions and carrots until translucent, about 5 minutes.
2. Add minced garlic, cumin, and smoked paprika. Cook for another minute until fragrant.
3. Pour in lentils, vegetable broth, and a can of diced tomatoes (with juices). Bring to a boil.
4. Reduce heat, cover, and simmer for 25-30 minutes. Check for tenderness—lentils should be soft but not mushy.
5. Uncover, taste and adjust salt and pepper. If it’s too thick, stir in a bit more broth; if too thin, simmer uncovered for 5-10 more minutes.
6. For a creamier texture, mash some lentils with the back of a spoon or use an immersion blender briefly.
7. Finish with a squeeze of lemon and chopped herbs. Serve hot, with crusty bread if you like.

Let the soup sit for 5 minutes before serving. Garnish with fresh herbs, a drizzle of olive oil, or lemon slices. Serve in warm bowls, paired with crusty bread.

How to Know It’s Done

• Lentils should be tender but hold their shape.
• The broth should be slightly thickened and fragrant.
• No raw garlic or spices should be detectable; they should be integrated into the aroma.

Cooking Tips & Tricks for Perfect Lentil Soup

• Sauté vegetables until sweet and fragrant—this builds flavor.
• Use hot broth to deglaze the pan—captures all those tasty bits.
• Keep an eye on the lentils—they cook quickly and turn mushy if overdone.
• Add acid at the end—lemon or vinegar brightens the entire dish.
• For extra richness, stir in a splash of coconut milk or olive oil just before serving.

Common Mistakes and How to Fix Them

• FORGOT TO RINSE LENTILS? Rinse again and simmer longer to avoid grit.
• DUMPED TOO MUCH SALT? Add a peeled potato to absorb excess salt, then discard.
• OVER-TORCHED SPICES? Rinse briefly with cold water, then start fresh with new spices.
• NO time to simmer? Use a pressure cooker to cut cooking time in half.

Quick Fixes for Common Lentil Soup Woes

• When too thick, splash in hot water or broth and stir.
• Splash a dash of vinegar if the soup tastes dull.
• Patch bland flavor with more garlic or spices.

• Add a squeeze of lemon for instant brightness.

Prepping and Storing Your Lentil Soup

• Chop vegetables a day ahead; store in airtight containers in the fridge for up to 24 hours.
• Cooked lentil soup keeps well in the fridge for 3-4 days. Reheat gently, stirring often.
• The flavors deepen overnight, making it even tastier the next day.
• Freeze in portions for up to 3 months. Thaw overnight in the fridge and reheat until steaming, watching for bubbling edges.
