Tips for Making the Best Hearty Lentil Soup

Rinse Lentils Well – Removes any debris and prevents bitterness.
Don’t Skip the Acid – Lemon juice or vinegar brightens the flavors.
Add Umami Boosters – A Parmesan rind or splash of soy sauce deepens the taste.
Adjust Thickness – Add more broth for a thinner soup or simmer longer for a thicker stew.

For a smoky twist, add a pinch of smoked paprika or liquid smoke.

Common Mistakes to Avoid

Overcooking the Lentils – They should be tender but not mushy.
Underseasoning – Taste and adjust salt & spices at the end.
Skipping the Sauté Step – Building flavor with onions, carrots, and celery is key.
Using Old Lentils – Older lentils take longer to cook; check for freshness.

Avoid these pitfalls for a perfectly balanced, flavorful soup.
