I’m always on the lookout for ways to eat more pasta while still keeping my nutrition a bit on track too… That’s because I could seriously eat pasta every single day of my life…

I recently passed by a question on Facebook where someone asked: “If you could only eat three foods for the rest of your life, what would they be?”

I started off on the right foot:

  1. Poke
  2. Ceviche

And then, my carb-loving, half Italian-blooded self came through:

3.   Pasta 

Seriously, I think I lived my entire high-school life eating pasta every day… My nana lived next door, and every day after school she would walk us over some of her pasta with sauce. So it’s only habit…

Here’s a pasta recipe that makes me feel a little better about things. It’s vegetarian, packed with fiber and nutrients. And, I made it all with the help of my Instant Pot. It seems whenever I’m cooking bean-based dishes lately, I always use the Instant Pot – It saves so much time, and I love how hands-free it makes the cooking process.

Instant Pot Lentil Bolognese Sauce can be made in no time with the help of your electric pressure cooker. It's vegetarian and packed with protein & fiber.

This Instant Pot Lentil Bolognese is loaded with veggies – Crimini mushrooms, carrots, celery, and tomatoes… And of course, I had to a glug or two of red wine…

Even though the Instant Pot makes things quicker, this lentil bolognese sauce will still take about 40 minutes from start to finish… Leaving you plenty of time to drink remaining red wine and start your pasta…

I like to serve this Instant Pot Lentil Bolognese over the pasta in big bowls topped with plenty of fresh grated Pecorino Romano cheese and a sprinkling of fresh basil. Highly suggested for not only Meatless Monday, but any day of the week.

Prep Time: 15 minutes mins
Cook Time: 20 minutes mins
Total Time: 45 minutes mins

Equipment

  • Instant Pot

Ingredients

  • 2 Tbsp. extra-virgin olive oil
  • 1 cup onion (minced)
  • 1 stalk celery (finely chopped)
  • 2 carrots (finely chopped)
  • 1 cup crimini mushrooms (finely chopped )
  • 4 cloves garlic (minced)
  • 2 Tbsp. tomato paste
  • 1/3 cup red wine
  • 1 cup dried lentils (rinsed)
  • 1 28-ounce can crushed tomatoes
  • 3/4 cup water
  • 1 bay leaf
  • 1 tsp dried thyme
  • 2 tsp dried oregano
  • Dash red pepper flakes
  • 1 Tbsp. balsamic vinegar
  • Coarse salt and black pepper (to taste)
  • 1 pound penne pasta (cooked)
  • Pecorino Romano cheese (grated or shaved)
  • Fresh basil (chopped (optional))

Instructions

  • Press the Sauté function key on your Instant Pot and heat the olive oil. Add the onion, celery, and carrots and season with salt and pepper. Keep the lid off and sauté for 5 minutes, or until the onions are clear and the vegetables are soft.
  • Add the mushrooms and garlic. Cook for 4 to 5 minutes, or until the mushrooms are soft and have released some liquid and the garlic is fragrant. Add the tomato paste and stir to incorporate, let brown for 2-3 minutes. Add the red wine and stir, scraping any browned bits from the bottom of the pot, let evaporate.
  • Add the lentils, tomatoes, water, and spices to the Instant Pot, close the steam release knob and set to manual for 20 minutes. Now is a good time to cook your pasta. When the Lentil Bolognese sauce is done cooking, allow the pressure to release naturally for 10 minutes. Stir in the balsamic vinegar, taste and adjust seasoning with salt and pepper. Serve over cooked pasta and top with grated cheese and fresh basil.

    As a mostly vegetarian, I like lentils, though 95% of the time I use them in soup. I should mix it up and try this – sounds like a delicious sauce!

      Thanks Catherine – I’m a huge fan of lentils and have noticed that this blog is become overwhelmed with all the lentil recipes lately!!! Do you have any favorite soup recipes that you enjoy with them?

    This makes me want to get an Instant Pot! Love the idea of a bolognese made with lentils – such a great vegetarian option. I’m going to keep this in mind for the future.

      Go for it! I had decided getting one was superfluous – until I was gifted one. Even so, I let it sit for months before I finally attempted to use it. Now I don’t think a day goes by that it isn’t used and appreciated, be it for batch cooking dried beans,(so much better than canned!) grains, porridge, potatoes, etc.; soups and stews; making plant based yogurt; desserts; tempeh, natto… you name it! My favorite attribute isn’t so much the time saved (varies) but the fact that I don’t have to stand over a hot stove babysitting recipes or burning pots here in FL!

    I don’t have an instant pot, so I made this recipe on the stove. The flavor was right on, but for some reason, my lentils never became fully tender ( I bought the lentils today and ended up simmering the sauce for an hour). When I make this recipe again, I will increase the amount of mushrooms and minimize or eliminate the lentils.. I enjoyed the excuse to open a bottle of wine when the recipe only called for 1/3 cup 😉

      This was absolutely because you didn’t use the Instant Pot. Her timing on the recipes are because of the pressure cooker.

        You can also soak the lentils overnight before cooking with them the next day, this will drastically reduce cooking time (though to what extent, I am unsure).

    This looks amazing! I was curious if you had any suggestions for a mushroom substitute? Thank you!

    I was very disappointed, I took all the time to prepare the meal and then got the “burn” error message on my instant pot. Thought maybe it was b/c I didn’t quite scrape everything off the bottom initially. Scraped it, added 1 cup broth to make sure there was enough liquid, tried again, and got the “burn” error message again. What a waste of 90 minutes.

      I’m so sorry to hear that Christina! I’ve never gotten a “burn” message on my Instant Pot… I’ve heard of others having this problem too though. No idea what might be causing it… I’m going to do some research!

        Exact same thing happened to me yesterday, and I was cooking for 15 people at a team retreat. Dinner was delayed by over an hour as I got the burn notice three times, and then eventually just simmered for 20minutes. Very frustrating. Flavours were amazing, but proportions did not work in the instant pot.

          I’m so sorry to hear that you and others are having this issue Katelynn. I’ve made this recipe several times and have had no issues. I’m going to test this out again very soon and see if I can figure out what may be happening. Thank you for the feedback.

            I got a burn notice too, scrapped the bottom and added a little vegetable broth. It worked great after that and the recipe was delicious! I think you just need to practice with the instant pot more if you keep getting burn notices.

      Just a thought but are you turning your Instant Pot off completely in between functions? I used to get the “burn” error. But I decided to turn off and actually unplug (perhaps overkill?!) in between sauté, and then setting the pressure part of recipe. This has totally fixed my problem. Have never gotten the burn indicator again.

      Hi Christina this happens to me all the time since I switched from a Crockpot brand electric pressure cooker to the IP (I NEVER had to seglaze anything in the Crockpot one and never had a problem! )
      Very disappointing. I hate the extra deglazing step (because it doesn’t work most times anyway!). I work around it now by doing any sauteeing in a seperate pan before putting it in the pot. It’s the only fail-safe way I’ve found to prevent that annoying burn error. Bummer to have to dirty an.extra pan for what should be a one pot recipe, but beats spending hours having several goes at cooking something only for it to end up failing.
      I have seen you can now order a non-stick pot for the IP to use instead of the standard one. I think that m8ght help. I’m going to order it and give it a try 🤞

    Delicioso! I didn’t have any celery, tomato paste or basil (used dried oregano), but this still turned out very well. (No burning. I have the impression that Instant Pots may not all be calibrated equally.) I will certainly check out your other IP recipes.

        Pretty late to the party here but this is often a problem for me too. I highly recommend either waiting to add canned tomatoes until after the lentils and veg. are done cooking, then heat again until simmering. Or else – after adding and stirring together the rest of the ingredients, gently pour the tomatoes over the top and DO NOT MIX, just seal and cook.

    I’m also frustrated. I have a brand new pressure cooker and I got a burn warning as well. It made a huge mess and I had to cook it on the stove. What kind of lentils did you use? They are many kinds maybe that’s the error?

      I’m so sorry Jacqueline – I used brown lentils. I’m definitely going to re-test this recipe. I’m so sorry that so many people are having issues with it.

        Hi Erin! I don’t have a pressure cooker but would love to try & make this on the stove. I know it will take a bit longer but that’s fine. Could you please give some insight on how to cook on the stove? Not too familiar with cooking with lentils but would love to start.

          Hi Jordan – I would bring it to a boil on the stove, and then allow the lentils to simmer for about 40 minutes. You may need to add in a bit more cooking liquid, as the instant pot cooking retains more liquid. Hope that helps!

    This was so good! I did get the burn notice once but opened the lid, really scraped the bottom well and pushed the bay leaf to the top so it wasn’t touching, it came right to presssure after that and cooked with no issues. Served with grated cheese over zucchini noodles. Will definitely go in the regular weekly dinner rotation!

      I’m so happy to hear that it worked out for you Libby! I’m still a bit confused by the burn error though. That shouldn’t be happening. I will be giving it another test out soon!
