There is something deeply comforting about a pot of lentil soup bubbling away on the stove. The kitchen fills with the smell of sweet onions, garlic and cumin, and the lentils soften into a thick, earthy, spoon-coating broth that feels far richer than the humble ingredients suggest.
This soup is built for the Daniel Fast, so everything in it is simple and whole: vegetables, legumes, herbs, olive oil and water. It works beautifully for a first day of the fast, a busy weeknight, or a big batch on Sunday that carries you through several lunches without any fuss.
SaveWhen I first tried the Daniel Fast, I worried I would miss flavor more than anything. A big pot of this soup changed my mind. A little smoked paprika, a squeeze of lemon at the end and a generous handful of parsley make every bowl taste bright and satisfying, and I never felt like I was going without.

Instructions
- Rinse the lentils
Place the lentils in a fine mesh strainer and rinse them under cold running water for about 30 seconds. Pick out any small stones or shriveled lentils, then set the strainer aside to drain while you prep the vegetables.
- Prep the vegetables
Dice the onion, carrots and celery into pieces about 1/2 inch in size so they cook evenly and become tender at the same pace as the lentils. Mince the garlic and keep it separate, since it cooks much faster than the other vegetables.
- Sauté the aromatics
Warm the olive oil in a large Dutch oven or soup pot over medium heat. Add the onion, carrots and celery with a pinch of the salt and cook for 7 to 8 minutes, stirring often, until the onion turns soft and translucent and just begins to pick up color.
- Add garlic and tomato paste
Stir in the garlic and tomato paste and cook for 1 minute, stirring constantly, until the paste darkens slightly and smells rich and fragrant. This short step deepens the flavor of the whole pot, so do not skip it.
- Toast the spices
Sprinkle in the cumin, smoked paprika and turmeric, then stir for 30 seconds so the spices bloom in the hot oil. Watch closely and lower the heat if anything starts to stick, because scorched spices turn bitter.
- Add lentils and liquid
Add the drained lentils, the diced tomatoes with their juices, the water or vegetable broth and the bay leaves. Scrape up any browned bits from the bottom of the pot with a wooden spoon, since they add plenty of savory depth to the broth.
- Bring to a simmer
Raise the heat to high and bring the soup to a boil, then reduce the heat to medium-low so it simmers gently. Partially cover the pot with the lid, leaving a small gap for steam to escape, and cook for 30 to 35 minutes, stirring every 10 minutes.
- Check the lentils
Taste a few lentils after 30 minutes. They should be completely tender with no chalky center but still hold their shape. If they are still firm, simmer for another 5 to 10 minutes, adding a splash of water if the soup looks too thick.
- Thicken the soup
Remove the bay leaves. For a creamier texture, use an immersion blender to pulse the soup 4 or 5 times, or scoop out about 2 cups, blend it in a regular blender until smooth and stir it back in. This thickens the broth without any flour or cream.
- Wilt the spinach
Stir in the spinach and the remaining salt and black pepper, then cook for 2 to 3 minutes just until the leaves wilt into the hot soup. Taste the broth and adjust the salt, since lentils soak up a lot of seasoning.
- Finish and serve
Turn off the heat and stir in the lemon juice and fresh parsley. The acidity brightens all the earthy flavors. Ladle the soup into warm bowls and serve right away.
Substitutions and variations
- Swap the carrots for diced sweet potato or butternut squash for a slightly sweeter, creamier soup.
- Use kale or Swiss chard instead of spinach, and simmer it for 5 minutes so the leaves turn tender.
- Red lentils work too, but they break down completely, so shorten the simmer to about 20 minutes for a smooth, thick soup.
- Replace the smoked paprika with 1/2 teaspoon dried thyme if you prefer a more herbal, less smoky flavor.
Chloe's tips
- Do not add the salt all at once at the start. Season lightly while sautéing, then finish at the end so you can balance the flavor once the lentils are tender.
- Check your canned tomatoes and vegetable broth labels carefully. Many brands add sugar, citric acid blends or flavorings that do not fit the Daniel Fast, so choose ones with only vegetables, water and salt.
- Always add the lemon juice at the end. Acid added early can keep lentils from softening properly.
- Lentils keep absorbing liquid as the soup rests, so thin leftovers with a splash of water when reheating.
How to store it
- Cool the soup completely, then refrigerate in an airtight container for up to 5 days.
- Freeze in portions for up to 3 months, leaving about an inch of space at the top of each container for expansion.
- Thaw overnight in the refrigerator and reheat gently on the stove over medium-low heat, stirring in a little water to loosen it.

Frequently asked questions
Is lentil soup allowed on the Daniel Fast?
Yes. Lentils are legumes, and legumes, vegetables, herbs, spices and olive oil are all part of the Daniel Fast. Just make sure your tomatoes and broth contain no added sugar, preservatives or animal products.
Do I need to soak the lentils first?
No. Brown and green lentils cook through in about 30 to 35 minutes without soaking. A quick rinse and a check for small stones is all they need.
How can I make the soup more filling?
Stir in a cup of cooked brown rice or diced sweet potato, or blend part of the soup for a thicker texture. A drizzle of olive oil on top also adds richness and satisfying fullness.
Can I make it in a slow cooker or Instant Pot?
Yes. Sauté the vegetables first, then cook everything except the spinach, lemon and parsley on low in a slow cooker for 7 to 8 hours, or pressure cook for 12 minutes with a natural release. Add the finishing ingredients at the end.
