How to Make Instant Pot Lentil Soup
Step 1: Sauté the Vegetables
Start by setting your Instant Pot to the sauté function. Add the olive oil and let it heat up before adding the onion, carrots, and celery.
This step builds a flavorful base by softening the vegetables and releasing their natural sweetness.
Step 2: Add Garlic and Spices
Once the vegetables are tender, stir in the garlic, cumin, smoked paprika, salt, and pepper. Sauté for another minute until fragrant.
This helps to awaken the spices, enhancing the overall flavor of the soup.
Step 3: Add Lentils and Broth
Next, stir in the dried lentils and pour in the vegetable broth. Make sure to scrape the bottom of the pot to avoid any burn warnings.
This ensures all the flavors meld together and prevents sticking during cooking.
Step 4: Incorporate Diced Tomatoes
Add the canned diced tomatoes, including their juices, to the pot. Stir everything together until well combined.
The tomatoes add acidity and depth, balancing the earthiness of the lentils.
Step 5: Pressure Cook the Soup
Seal the Instant Pot lid and set it to cook on high pressure for 15 minutes. Once done, allow for a natural pressure release for 10 minutes before releasing any remaining pressure.
This cooking method helps the lentils become tender without losing their shape.
Step 6: Stir in Greens
After releasing the pressure, open the lid and add the chopped spinach or kale. Stir until wilted and bright green.
This adds a pop of color and nutrients, making your soup even more wholesome.
Step 7: Adjust Seasoning
Taste the soup and adjust the seasoning if needed. A splash of lemon juice can brighten up the flavors.
This is your chance to make it just right for your taste buds!
Step 8: Serve and Enjoy
Finally, ladle the soup into bowls and serve hot. Pair it with crusty bread or a side salad for a complete meal.
This soup is perfect for lunch or dinner and makes great leftovers too!
Pro Tip: Let the soup sit for a few minutes before serving to allow the flavors to deepen.
