How to Make Instant Pot Lentil Soup Recipe
Step 1: Sauté the Base Vegetables
Set your Instant Pot to the ‘Sauté’ function and pour in the olive oil. This heat is just right to soften your diced onion, carrots, and celery. Cook them gently for about 5 minutes until they start to become tender and fragrant. This step creates the flavor foundation, so take your time letting the vegetables develop their sweetness and complexity.
Step 2: Add Garlic and Stir
Once the veggies are soft and inviting, stir in the minced garlic and sauté for an additional minute. Garlic releases its wonderful aroma quickly and this brief cooking ensures it won’t burn but will add that unmistakable warmth to the soup’s base.
Step 3: Combine Lentils and Seasonings
Now, add your rinsed lentils, canned diced tomatoes with their juices, vegetable broth, dried thyme, oregano, bay leaves, salt, and black pepper. Give everything a good stir so the lentils mingle with the savory broth and herbs. This mixture is going to be the hearty core of your soup journey.
Step 4: Pressure Cook the Soup
Secure the Instant Pot lid and set the valve to ‘Sealing.’ Select ‘Pressure Cook’ or ‘Manual’ mode and set the cook time for 15 minutes on high pressure. This step is where the magic happens—lentils become tender, flavors marry, and the soup thickens beautifully in no time at all.
Step 5: Release Pressure and Finish
After cooking, let the pressure naturally release for 10 minutes to keep the lentils tender and intact. Then carefully turn the valve to ‘Venting’ to release any remaining pressure before opening the lid. Stir in your chopped spinach or kale until just wilted, add lemon juice if you’d like a zesty lift, and adjust seasoning to taste. This final step adds a fresh, bright color and zing that really wakes up the flavors.
How to Serve Instant Pot Lentil Soup Recipe
Garnishes
A sprinkle of freshly chopped parsley on top is all you need to elevate your soup into something feel-good pretty. The parsley adds a lovely green contrast and a subtle herbal freshness that balances the earthy lentils wonderfully.
Side Dishes
This soup pairs beautifully with crusty bread or warm pita for dipping, or a simple green salad for an extra vegetable boost. If you want something more filling, try serving alongside roasted potatoes or a grain salad for varied textures and tastes.
Creative Ways to Present
For a fun twist, serve this soup in hollowed-out mini pumpkins or bread bowls to impress guests effortlessly. You can also drizzle a little plain yogurt or a dollop of sour cream on top for creamy tanginess that complements the soup’s heartiness perfectly.
Make Ahead and Storage
Storing Leftovers
Once cooled, store any leftover Instant Pot Lentil Soup Recipe in an airtight container and keep it in the fridge for up to 3-4 days. This gives you plenty of time to enjoy it again without sacrificing freshness or flavor.
Freezing
This soup freezes beautifully—just pour it into freezer-safe containers or bags, leaving room for expansion, and freeze for up to 3 months. When you’re ready to enjoy, thaw overnight in the fridge before reheating.
Reheating
Reheat your soup gently on the stove over medium heat, stirring occasionally until warmed through. If the soup has thickened too much, add a splash of vegetable broth or water to reach your desired consistency. You can also reheat it in the microwave in short bursts, stirring in between.
FAQs
Can I use red lentils instead of brown or green?
Red lentils cook faster and tend to break down more, resulting in a creamier texture. If you prefer that consistency, red lentils work well, but reduce cook time to about 8-10 minutes to avoid mushiness.
Do I need to soak the lentils before cooking?
There’s no need to soak lentils for this Instant Pot Lentil Soup Recipe since the pressure cooking softens them quickly. Just be sure to rinse and drain them well before adding to the pot.
Can I make this soup vegan?
Absolutely! This recipe is already vegan, using vegetable broth and plant-based ingredients, making it a perfect meat-free meal option.
What can I substitute for fresh spinach or kale?
Feel free to swap in other greens like Swiss chard or collard greens. Just chop them finely and stir in at the end until wilted.
How spicy is this soup?
This soup has a mild warmth from black pepper and herbs but no added heat. If you like spicy, you can add red pepper flakes or a dash of hot sauce when serving.
