Vegetable Lentil Soup is a warm, healthy dish made with tender lentils, carrots, celery, and tomatoes. It’s simple to make and perfect for cozy days when you want a nutritious meal.
I like to add a dash of lemon juice at the end—it brightens the flavors. Sometimes I sneak in a little spinach for extra greens!
For a quick option, I cook the soup in a pressure cooker. It saves time and makes the lentils super soft and delicious.
Ingredients & Substitutions
Red lentils: These cook quickly and become soft, giving the soup its hearty texture. I recommend rinsing them well to remove dirt. If you don’t have red lentils, yellow lentils are a good substitute—they cook similarly.
Carrots: They add natural sweetness and color. For a milder flavor, try parsnips instead. I like chopping them small for quicker cooking; larger pieces can be used for chunkier texture.
Celery: It provides a fresh, slightly bitter note. If you’re out, chopped fennel can add a similar aromatic touch. Always chop into small pieces so it softens in the simmering process.
Onion: Adds depth and flavor. Yellow or sweet onions are best, but shallots can be used for a milder taste. Add early so they soften nicely and dissolve into the broth.
Vegetable broth: It forms the soup’s liquid base. Use low-sodium broth to control salt or try chicken broth if you prefer a richer flavor. Homemade broth makes it even tastier!
How do I better chop vegetables evenly?
I keep my knife sharp and use a stable cutting board. Cut vegetables into uniform pieces for even cooking. Cut with a rocking motion and hold the veggie steadily with your fingertips tucked in. Practice makes perfect, so take your time.
- Make sure your knife is sharp for safety and control.
- Slice vegetables into similar-sized pieces, about ¼ to ½ inch thick.
- Keep the cutting motion steady, slicing down smoothly.
- Hold the veggie with your fingertips curled under to protect them.
