How to Make Instant Pot Lentil Soup
The Ingredients You’ll Need
Gather these simple ingredients:
- 2 tablespoons extra-virgin olive oil
- 1 medium yellow onion, small diced
- 4 medium carrots, diced
- 3 stalks celery, diced
- 4 sprigs fresh thyme
- 1 teaspoon kosher salt
- ¾ teaspoon smoked paprika
- ½ teaspoon ground black pepper
- 1 ½ cups French green lentils
- 4 cloves garlic, minced (about 4 teaspoons)
- 1 can fire-roasted diced tomatoes (15 ounces)
- 1 can crushed tomatoes (15 ounces)
- 4 cups low-sodium vegetable broth
- Chopped fresh parsley (for serving)
- Freshly grated Parmesan cheese (optional for serving)
- Crusty bread (optional for serving)
Step-by-Step Cooking Instructions
Let’s get cooking! Start by heating olive oil in your instant pot using the sauté setting. Add the diced onion and cook until it becomes soft and begins to brown, about 8 minutes.
Meanwhile, prepare the carrots and celery. Add them to the pot, along with thyme, salt, smoked paprika, and black pepper. Sauté for around 2 minutes until these vegetables soften slightly.
Next, stir in the lentils and minced garlic, cooking for another 30 seconds until fragrant. Then, pour in the fire-roasted diced tomatoes, crushed tomatoes, and vegetable broth.
Seal the instant pot and cook on HIGH pressure for 15 minutes. After cooking, allow the pressure to release naturally for 10 to 15 minutes before opening the lid. Give the soup a good stir, remove the thyme stems, and adjust the consistency with water or broth if desired. Season to taste and serve hot, garnished with parsley, Parmesan, and crusty bread if you’d like.
Tips for Perfecting Your Soup
For best results, always rinse your lentils before using them. This removes any debris and ensures a clean flavor. Also, feel free to adjust the seasonings to match your personal taste. Enjoy experimenting with different herbs and spices!
Variations and Customizations
Adding Proteins: Sausage, Bacon, or Ham
You can easily add protein to your instant pot lentil soup. Sausage, bacon, or ham can bring a savory depth to the dish. Just sauté them along with the onions for a rich flavor.
Vegan Alternatives and Ingredient Swaps
If you’re looking for vegan alternatives, consider adding mushrooms or kale for a hearty texture. You can also swap out the vegetable broth for mushroom broth for an enhanced umami flavor.
Cooking on the Stovetop
If you prefer the stovetop method, follow the same steps up to adding the broth. Bring to a boil, cover, and simmer until the lentils are tender, about 25 minutes. You’ll still enjoy a delightful, comforting soup!
Storing and Reheating Your Lentil Soup
Best Practices for Storing Leftovers
To store your leftover soup, place it in an airtight container in the refrigerator. It can last up to 5 days, allowing you to enjoy this comforting dish several times!
How to Reheat for Optimal Flavor
When reheating, warm the soup gently on the stove over medium-low heat or in the microwave. This helps maintain its rich flavors and texture.
Freezing Lentil Soup for Future Meals
To freeze your soup, store it in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating, so it tastes just as delightful as the first time.
