Jake said it tasted like “real food,” which from an 11-year-old is basically a Michelin star. Let’s talk ingredients.
What You Need for This Savory Lentil Stew
The best part? You probably have most of this stuff already. Brown or green lentils work great here, they hold their shape better than red ones and give you that hearty bite.
✔ Avocado oil : high smoke point, doesn’t overpower the flavors
✔ Fire-roasted tomatoes : adds a subtle smokiness regular diced tomatoes can’t match
✔ Russet potato : breaks down just enough to thicken the stew naturally
✔ Brown or green lentils : stay firm, don’t turn to mush
✔ Chicken broth : use veggie broth if you want to keep it vegetarian (think Instant Pot chicken breast soup base)
The tomato paste deepens everything. Don’t skip it.
Alright, now let’s actually make this thing.
How to Make This Rich and Thick Lentil Stew
First time I made this, I forgot to rinse the lentils. Worked fine, but the broth was cloudier than I wanted.
Here’s how it goes:
- Turn the Instant Pot to sauté and heat the avocado oil until it shimmers.
- Toss in the carrot, celery, and onion, let them soften for about 4 minutes.
- Add the garlic and cook until fragrant, maybe 30 seconds.
- Stir in the lentils, fire-roasted tomatoes, chicken broth, and all the spices.
- Lock the lid, set to high pressure for 15 minutes.
- Let it naturally release for 10 minutes, then quick-release the rest.
- Stir in the cubed potato and Parmesan if you’re using it.
That’s the core of it. But you can mess around with the recipe if you want.
Ways to Switch Up Your Instant Pot Lentil Stew
Honestly, this stew is pretty forgiving. I’ve made it a dozen ways.
Smoky Version
Add a teaspoon of smoked paprika and a pinch of cumin when you sauté the aromatics. The fire-roasted tomatoes already give you some depth, but this takes it further. Sarah likes it spicy, so sometimes I throw in red pepper flakes too. The whole kitchen smells like a Texas barbecue joint.
Creamy Comfort
Stir in half a cup of heavy cream or coconut milk right before serving. It turns the stew into this velvety, stick-to-your-ribs kind of meal. Sophie asks for this version on repeat. The thyme and rosemary still shine through, just with a richer backdrop.
If you’re feeling wild, throw in some sausage or bacon. Not traditional, but it works.
What to Serve with This Bean Stew
At home, we always serve it with crusty sourdough. The kind you tear apart and dip straight into the bowl.
Garlic Bread
Toast some slices with butter, garlic powder, and a sprinkle of Parmesan. Jake could eat an entire loaf by himself. The crunch against the thick texture of the stew is unbeatable.
Simple Green Salad
Arugula, lemon juice, olive oil, salt. That’s it. Cuts through the richness and makes you feel like you’re eating something virtuous. Even when you’re on your second bowl of stew.
Roasted Root Vegetables
Carrots, parsnips, sweet potatoes, toss them with olive oil and roast at 425°F until caramelized. The sweetness plays well with the savory lentil stew. I usually make extra and throw them in the stew the next day.
Sometimes we skip sides entirely. This stew is hearty enough on its own. Or go veg with Instant Pot Minestrone Soup.
Keeping Your Lentil Stew Fresh
This instant pot stew gets better the next day. The flavors meld, the potatoes soak up the broth, and everything just tastes richer.
Storage
- At room temperature: Not recommended, lentils can go off pretty fast.
- In the fridge: Up to 5 days in an airtight container.
- In the freezer: About 3 months. Let it cool completely before freezing, and leave some headspace in the container.
Reheating
Microwave works fine for a single serving, cover it and stir halfway through. For bigger portions, reheat on the stove over medium heat. Add a splash of broth or water if it’s too thick. The Instant Pot’s sauté function also works if you’ve got leftovers in the pot already.
Anti-waste tip
Blend leftover stew with some extra broth and turn it into a creamy soup. Or spread it over toast with a fried egg on top. Sounds weird, tastes incredible.
Still got questions? I figured you might.
Questions About This Hearty Instant Pot Lentil Stew
I had the same doubts the first time I made this. Lentils seemed tricky, and I wasn’t sure about the slow pressure release.
Can I use red lentils instead of brown or green lentils?
Red lentils break down fast and turn mushy. Stick with brown or green if you want that hearty texture.
How do I make lentil stew thicker?
Mash some of the potatoes against the side of the pot. Happened to me too, instant fix.
Can I add more vegetables to this instant pot lentil stew?
Absolutely. I found that if you toss in kale or spinach at the end, it wilts perfectly without getting slimy.
Why did my lentil stew turn out watery?
You might’ve used too much broth or skipped the natural release. Let it sit sealed for 10 minutes, it thickens up.
The Complete Instant Pot Sweet Potato Mash Recipe
Instant Pot Lentil Stew
Equipment
- Instant Pot (6-quart or larger)
- Cutting board
- chef’s knife
- Measuring cups and spoons
Ingredients
- 1 tablespoon avocado oil
- 1 carrot peeled and diced
- 2 celery stalks diced
- 1 small yellow onion finely chopped
- 1 russet potato peeled and cubed
- 3 garlic cloves minced
- 1½ cups brown or green lentils
- 1 can (14.5 oz) diced fire-roasted tomatoes
- 4 cups chicken broth
- 2 bay leaves
- 1½ teaspoons salt
- ½ teaspoon freshly ground black pepper
- 1 teaspoon dried oregano
- ½ teaspoon paprika
- ¼ teaspoon ground cumin
- ¼ cup grated Parmesan cheese optional
Instructions
- Turn the Instant Pot to sauté mode and add the avocado oil.
- Once the oil shimmers, add the diced carrot, celery, and onion. Cook for 4 minutes, stirring occasionally, until softened.
- Add the minced garlic and cook for 30 seconds until fragrant.
- Stir in the lentils, fire-roasted tomatoes, chicken broth, bay leaves, salt, pepper, oregano, paprika, and cumin.
- Lock the lid, set the valve to sealing, and cook on high pressure for 15 minutes.
- When the timer goes off, let the pressure release naturally for 10 minutes, then quick-release the remaining pressure.
- Remove the bay leaves. Stir in the cubed potato and Parmesan if using. The potatoes will soften from the residual heat in about 5 minutes.
- Taste and adjust seasoning if needed. Serve hot.
Notes
- If you want a vegetarian version, swap the chicken broth for vegetable broth. Works just as well. The stew thickens as it sits, so if you’re reheating leftovers, add a splash of broth or water to loosen it up. I’ve tried this with sweet potatoes instead of russets — it adds a subtle sweetness that some might love. Top it with a dollop of sour cream and fresh parsley for added flavor.
