Traditional Lentil Soup Recipe (Easy!)

I always come back to this Traditional Lentil Soup Recipe when I want something hearty, comforting, and made with simple pantry staples. It's an easy lentil soup recipe that tastes like it's been simmering all day, even though it's ready in less than an hour.

Tender green lentils, smoky bacon, vegetables, and warm spices come together to create a rich homemade soup that's filling without being heavy. Every spoonful is packed with cozy flavors that make it perfect for chilly evenings or easy family dinners.

It reminds me of the kind of soup Grandma would keep bubbling on the stove, ready whenever someone walked through the door hungry.

What You Need to Know

• This old fashioned lentil soup is thick, hearty, and loaded with tender vegetables and green lentils.
• The soup tastes even better the next day, making it perfect for meal prep or leftovers.
• You can easily make it ahead and freeze individual portions for quick lunches.
• For a lighter version, skip the bacon and use vegetable broth with a drizzle of olive oil before serving.

Ingredients Overview

• Bacon: Thick-cut or regular bacon both work well. Turkey bacon can be substituted for a lighter option.
• Olive oil: If your bacon releases plenty of fat, you can reduce or skip the olive oil.
• Onion: Yellow onions are traditional, but sweet onions or white onions work just as well.
• Carrots: Regular carrots add classic flavor, though baby carrots diced into small pieces can be used.
• Celery: If you're out of celery, extra carrots or diced fennel make a good substitute.
• Garlic: Fresh garlic gives the best flavor, but 1 teaspoon of garlic powder works in a pinch.
• Brown or green lentils: These hold their shape beautifully. Avoid red lentils since they become much softer.
• Diced tomatoes: Fire roasted tomatoes add extra depth if you enjoy a richer flavor.
• Vegetable or chicken broth: Vegetable broth keeps the soup vegetarian if you omit the bacon, while chicken broth adds a richer taste.
• Cumin and paprika: Smoked paprika adds an extra hint of smoky flavor if you have it.
• Bay leaves: Fresh or dried both work. Just remember to remove them before serving.
• Red or white wine vinegar: A splash at the end brightens the soup. Lemon juice also works well.
• Fresh parsley or cilantro: Adds freshness just before serving.

How to Make Traditional Lentil Soup Recipe

Step 1: Cook the chopped bacon in a large Dutch oven or soup pot over medium heat until crisp. Remove the bacon with a slotted spoon and set it aside, leaving about 1 tablespoon of bacon drippings in the pot. Add the olive oil if needed.

Step 2: Add the diced onion, carrots, and celery. Cook for 5 to 7 minutes until the vegetables begin to soften. Stir in the minced garlic and cook for another 30 seconds until fragrant.

Step 3: Stir in the rinsed lentils, diced tomatoes, broth, cumin, paprika, bay leaves, salt, and pepper. Return most of the cooked bacon to the pot, saving a little for garnish if desired.

Step 4: Bring the soup to a gentle boil, then reduce the heat to low. Cover and simmer for 30 to 35 minutes until the lentils are tender. Remove the bay leaves and stir in the vinegar. Taste and adjust the seasoning before serving with fresh parsley or cilantro.

Grandma's Tips

• Always rinse your lentils before cooking to remove any small bits of debris.
• Let the soup rest for 10 minutes before serving. The flavors continue to develop as it sits.
• If your soup becomes too thick, simply stir in a little extra broth until it reaches your favorite consistency.

Modern Updates

• Add chopped kale or fresh spinach during the last few minutes of cooking for extra vegetables.
• Use turkey bacon or leave the bacon out entirely for a lighter homemade lentil soup.
• Blend one or two cups of the soup and stir it back in for a creamier texture without adding dairy.

FAQs

What is the best type of lentil for traditional lentil soup?

Brown or green lentils are the best choice because they hold their shape while becoming tender during cooking. Red lentils cook much faster and create a softer, creamier soup.

Do you need to soak lentils before making soup?

No. Lentils cook quickly and do not need to be soaked beforehand. Simply rinse them well before adding them to the pot.

Why does lentil soup taste better the next day?

As the soup rests, the lentils absorb more of the broth and the flavors continue to blend together, making leftovers even more flavorful.

How do you make lentil soup thicker?

For a thicker soup, mash some of the cooked lentils with a spoon or blend one or two cups of the soup before stirring it back into the pot. This creates a naturally creamy texture without adding cream.
