Ingredients for This Instant Pot Lentil Soup

To make this hearty and flavorful Instant Pot Lentil Soup, you’ll need the following ingredients:

Main Ingredients:

1 lb ground beef (or substitute with ground turkey for a leaner option)
1 cup lentils (green or brown, rinsed and drained)
1 medium onion, diced
3 carrots, chopped
2 celery stalks, chopped
3 cloves garlic, minced
1 can (15 oz) diced tomatoes (with juice)
1 can (15 oz) kidney beans or pinto beans, drained and rinsed
4 cups beef or vegetable broth (low-sodium preferred)
1 cup water
1 teaspoon salt (adjust to taste)
½ teaspoon black pepper
1 teaspoon smoked paprika (adds a rich, smoky flavor)
1 teaspoon cumin (for warmth and depth)
1 teaspoon dried oregano
½ teaspoon red pepper flakes (optional, for heat)
1 bay leaf

Optional Garnishes:

Fresh parsley, chopped
A squeeze of lemon juice for added brightness
Grated Parmesan cheese

These ingredients work together to create a well-balanced and nourishing soup, packed with protein, fiber, and bold flavors.

Notes

Lentil Variety Matters: Green or brown lentils work best as they hold their shape well during cooking. Red lentils tend to break down, making the soup thicker.
Adjust the Thickness: If you prefer a thicker soup, let it sit for 10–15 minutes after cooking. For a thinner consistency, add more broth or water.
Make It Vegetarian: Simply omit the ground beef and use vegetable broth instead of beef broth. Adding extra beans or mushrooms can boost the texture and protein content.
Flavor Boost: A splash of lemon juice or a dash of balsamic vinegar at the end enhances the flavors beautifully.
Spice It Up: If you love heat, increase the red pepper flakes or add a dash of hot sauce before serving.

Watch Out for These Mistakes While Cooking

Not Rinsing the Lentils: Lentils often have dust or small debris, so rinsing them thoroughly is essential.
Skipping the Sauté Step: Browning the beef and sautéing the vegetables before pressure cooking enhances the overall flavor.
Forgetting to Deglaze the Pot: After sautéing, always scrape up any browned bits with broth to prevent the dreaded “burn” warning on your Instant Pot.
Overfilling the Instant Pot: Lentils and beans expand while cooking, so ensure there’s enough room for everything to cook evenly.
Releasing Pressure Too Soon: Allowing a natural release for at least 10 minutes prevents liquid from splattering and ensures the lentils are fully cooked.

Avoiding these common mistakes will ensure your Instant Pot Lentil Soup turns out flavorful, hearty, and perfectly cooked every time!

Frequently Asked Questions

1. Can I use a different type of lentils?

Yes! Green and brown lentils hold their shape best. Red lentils will break down more, creating a thicker, stew-like consistency.

2. How can I make this soup vegetarian?

Simply omit the ground beef and use vegetable broth instead of beef broth. You can add extra beans, mushrooms, or even diced sweet potatoes for added texture and protein.

3. Can I cook this soup on the stovetop instead of an Instant Pot?

Absolutely! Sauté the vegetables and beef in a large pot, then add the remaining ingredients. Simmer for about 35–40 minutes or until the lentils are tender.

Make sure to deglaze the pot after sautéing by adding a little broth and scraping up any browned bits before pressure cooking.

A splash of lemon juice, a dash of balsamic vinegar, or even a pinch of smoked paprika can enhance the depth of flavor.

7. What can I do if my soup is too thick?

Simply add more broth or water and stir well until you reach your desired consistency.
