Gathering Ingredients for Your Instant Pot Tomato Lentil Soup

Okay, let’s get our mise en place ready! Since we are relying on the speed of the IP, we need to make sure every ingredient is prepped and ready to drop right in. This recipe uses pantry staples, which is another reason I love it so much for those days when the fridge is looking a little bare. Remember, this entire batch is naturally vegan, which keeps things simple and incredibly healthy!

Here’s what you’ll need lined up on the counter:

• A good glug of olive oil—about 1 tablespoon to start in the pot.
• 1 large yellow onion, finely chopped. We want these soft and sweet, so chop them medium-small.
• 2 carrots and 2 celery stalks, both chopped nicely. These are the flavor backbone, so dice them small enough to vanish into the soup base eventually.
• 3 cloves of garlic, minced as fine as you can manage. Garlic wakes up right away, so we save it for later!
• We need our herbs: 1 teaspoon of dried thyme and 1/2 teaspoon of dried oregano. A tiny pinch of red pepper flakes goes in early if you like a little background warmth—totally optional!
• The star: 1 cup of red lentils. This is super important—you must rinse these thoroughly under cold water until the water runs mostly clear. It washes off the surface starch that can sometimes cause foaming in the pressure cooker.
• One big 28-ounce can of crushed tomatoes. Don’t grab diced; we want the crushed texture for that creamy base.
• 6 cups of vegetable broth. Use your favorite brand, but make sure it’s low sodium, so we can control the salt at the end.
• Finally, flavor boosters: 1 teaspoon of salt, 1/2 teaspoon of black pepper, and 1 tablespoon of tomato paste for an extra punch of depth.

Once everything is chopped and measured, cooking is seriously a breeze. If you’re looking for a different kind of hearty, check out my old-fashioned vegetable and beef soup for comparison!

Step-by-Step Instructions for Quick Tomato Lentil Soup IP

This is where the magic happens, and I promise, it’s so easy! We are using the Sauté function first, which is the secret sauce to any fantastic Instant Pot soup recipe that tastes like it took hours. Throwing those aromatics in the hot oil first builds a depth of flavor you just can’t skip, even when you’re trying to get dinner out fast!

Sautéing Aromatics and Building Flavor

First things first, set your Instant Pot to the Sauté function—medium heat is perfect. Drop in that tablespoon of olive oil. Once it shimmers a bit, toss in your chopped onion, carrots, and celery. Let them cook down, stirring occasionally, for about 5 minutes until they start looking soft. Don’t rush this part; you want them sweet! Then, add your minced garlic, thyme, oregano, and those optional red pepper flakes. You only need about 60 seconds here until that garlicky smell fills your kitchen. Wow, that’s the scent of a fantastic dinner coming together!

Pressure Cooking the Instant Pot Tomato Lentil Soup

Once the spices are fragrant, press Cancel to turn off the Sauté function. Now, dump everything else in: your rinsed red lentils, the can of crushed tomatoes, the vegetable broth, salt, pepper, and that little spoonful of tomato paste. Give it a good stir around the bottom, making sure nothing is sticking. Lock that lid on, make sure the valve is set to Sealing, and go hit Manual or Pressure Cook on High for exactly 10 minutes. That’s it! After the 10 minutes are up, resist the urge to open it right away. Let it sit for a **10-minute Natural Pressure Release (NPR)**. Then, very carefully, move the valve to Venting for the quick release of any last bit of steam. Always refer to my guides on pressure cooker tomato soup with lentils if you ever get confused on the release!

Achieving the Perfect Texture

When you open the lid (watch out for steam!), give the soup a good stir. The red lentils should have mostly dissolved, which is what gives us that lovely, creamy body without any actual cream. If you like yours a little smoother, now is the time! Grab your immersion blender and blend for just a few quick zaps—don’t make it totally puréed unless that’s your thing. I just like to smooth out the chunks of carrot a bit. Finally, the most important step: taste it! Does it need more salt? A pinch more pepper to wake it up? Adjust those seasonings right now before you serve it up!

Expert Tips for the Best Instant Pot Lentil Soup Recipe

You know, even with a simple recipe like this, those little details make a huge difference between a good soup and an absolutely incredible bowl of comfort. I went through my notes section for the Instant Pot Lentil Soup recipe, and these are the things I swear by. First, let’s talk about that rinsing step again! I know it seems fussy, but washing those red lentils until the water is clear really helps keep the pressure cooking smooth, trust me on that one.

Now, for the creaminess—since we are keeping this vegan, we have some fun options. If you want it truly luxurious, you can blend in 1/2 cup of raw cashews that you soaked in hot water for 30 minutes, or just swirl in 1/2 cup of full-fat coconut milk right at the end. Wow, that turns it into something restaurant-worthy!

My personal favorite tip? I always make a double batch. After the first day, the flavors in this Healthy Red Lentil Tomato Soup IP settle in and get even deeper. I use the leftovers the next day as the base for a totally different meal—maybe thinning it slightly and adding some cooked pasta, or blending it down even further into a dip for crackers. It saves me from thinking about dinner the next day!

Serving Suggestions for Hearty Tomato and Lentil Stew Instant Pot

Even though this Hearty Tomato and Lentil Stew Instant Pot is robust enough to stand alone, serving it up with the right accompaniment just elevates the whole experience, doesn’t it? Since it’s savory and slightly tangy from those tomatoes, you want something simple to go with it.

My number one suggestion, always, is bread. You need something crusty to soak up every last drop of that flavorful broth. I’m talking about a fantastic, crusty sourdough loaf. Or, if you’re feeling a little fancier but still keeping it easy, you absolutely must try making my easy homemade garlic breadsticks to dip!

If you want to lean into the freshness, a simple side salad with a bright lemon vinaigrette cuts through the richness of the stew beautifully. And for those nights when you want pure comfort food vibes? This soup is incredible paired with a gooey (and totally vegan, if you need it to be!) grilled cheese sandwich for dipping. Seriously, it’s the perfect match!

Storage and Reheating Your Vegan Lentil Soup Instant Pot Instructions

Lentil soup is honestly one of those magical things that tastes even better the next day, so I always try to make extra! Just remember what I mentioned earlier: this Vegan Lentil Soup Instant Pot instructions soup thickens up a *ton* overnight as those lentils just keep absorbing liquid. If you pack it up straight away, it might feel like stew the next morning!

For storage, pop any leftovers into an airtight container—I love using glass mason jars for this—and keep it in the fridge for up to four days. If you’re looking further ahead, this freezes like a dream! Freeze individual portions in freezer bags flat on a baking sheet for easy stacking later. When you reheat it, just add a splash of extra broth or water to bring it back to that perfect, dippable consistency. So simple for meal prepping!

Frequently Asked Questions About This Quick Tomato Lentil Soup IP

I always get so many questions when I post a recipe that’s this simple, because people worry that easy means compromises—but not here! I gathered some of the most common queries I hear about making this Quick Tomato Lentil Soup IP.

If you’ve got a question, chances are someone else is wondering too. I’ve tried to make sure this Easy Vegetarian Pressure Cooker Soup works for everyone, whether you’re a total beginner or you practically live in your Instant Pot!

Can I use brown or green lentils instead of red for this Instant Pot Tomato Lentil Soup?

That’s a super common question! I really recommend sticking to the red lentils for this specific recipe. See, red lentils are meant to completely break down during cooking. That breakdown is what gives us that creamy, velvety texture without having to add any dairy or nuts. If you swap in brown or green lentils, they hold their shape way better—you’ll end up with more of a chunky stew consistency rather than the smooth soup we’re going for here.

If you absolutely can’t find red lentils and have to use the others, you’ll need to adjust your pressure time. I’d suggest cooking them for about 12 to 15 minutes on High Pressure instead of 10, and you might want to give it a longer Natural Pressure Release to help them soften up a bit more. But for the absolute best result matching my recipe, go red!

How do I make this recipe gluten-free?

Good news! This recipe is naturally gluten-free, which is fantastic for keeping things simple! The lentils, the tomatoes, the vegetables—they are all naturally free of gluten. My main piece of advice here, and this goes for any recipe, is to double-check your vegetable broth. Sometimes broth concentrates or bouillon cubes can have sneaky additives, so just look for a brand that specifically states it’s certified gluten-free. Everything else you’re using is completely safe for a celiac-friendly meal!
