Instant Pot Lentils with Smoked Sausage

Book Club Casserole

“Casseroles are my go-to food when I’m cooking for a crowd and I don’t want to spend a lot of time on it. Here’s a recipe that’s easy to make as well as tasty, a hard combination to beat.” –MotherDaughterBookClub.com

This recipe is surprisingly super delicious. I know you’re thinking that lentils are boring and indeed they can be. But this recipe is not boring. It is full of flavor with just a handful of ingredients and a few minutes of prep time. This will give you more time to tidy the house before your book club friends arrive.

The lentils are flavored by the smoked sausage (so get a brand you love) and the seasonings. Lentils cook much quicker than dried beans and there is no soaking. The lentils turn out almost creamy. Legumes are such a healthy food, we all need to eat more of them, I am told. So try out this recipe soon!

Ingredients/Substitution Ideas

  • Olive oil
  • Beef smoked sausage–or andouille sausage, ham, kielbasa
  • Onion
  • Chicken broth–or water and Better than Bouillon chicken base
  • Brown/green lentils–if you use red lentils use a 3 minute pressure cook time instead
  • Petite diced tomatoes–or crushed tomatoes
  • Sugar
  • Black pepper
  • Garlic powder
  • Red pepper flakes
  • Cornstarch
  • Mozzarella cheese

Steps

Turn Instant Pot to saute setting. When display says hot add in the oil and swirl it around. Add in the smoked sausage and brown for about 4 minutes.

Add in the onion and saute for 3 minutes. 

Pour in the broth and scrape bottom of pot so that nothing is sticking. Turn off Instant Pot. Sprinkle in the lentils. Dump in the tomatoes, sugar, pepper, garlic powder and red pepper flakes. Don’t stir. 

Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 5 minutes for al dente lentils or 7 minutes for soft lentils. Let pot sit for 5 minutes and then move valve to venting and remove the lid.

Stir. If it needs to be thickened stir cornstarch together with equal parts cold water and stir it into the pot on the saute setting until sauce thickens. 

Sprinkle cheese on top and let it melt. Serve and enjoy!

  • Serve with a charcuterie board full of crackers, cheese, pretzels, olives, fruits, vegetables and dips.
  • This recipe is gluten free. It can be dairy free if you leave out the mozzarella.

  • I used my 6 quart Instant Pot*. You can also make this in a 3 or 8 quart pot. This recipe can easily be doubled or tripled for a crowd.
  • Store leftovers in an airtight container* in the refrigerator for up to 5 days or in the freezer for up to 3 months.

    any chance someone has made this with chicken or any other lean protein??

    we’ve made it frequently as written and it’s amazing (I don’t even need the cheese…….sometimes my husband will put grated Parmesan on top)

    I crave lentils when the weather turns cooler. I made this in the slow cooker. A delicious bowl of hearty, yummy goodness and super easy to put together. Loved it.

    Oooohhhh! This one just jumped to the top of the “list”! We love lentils at this house. I just read the ingredients out loud to my hubby & told him if he was a ‘good boy’ tomorrow I’d make this for dinner. He thought about it for about 10 seconds & said “if you make cornbread too, it’s a deal!” Plz don’t tell him I’m making it anyway. Sorry, not sorry. Will be back with stars.

    Not a comment, but a question.
    This sounds interesting.
    I don’t have an instant pot, or pressure cooker.
    Can I cook this on top of the stove or in the oven?
    Thank you,

      Yes I’m sure you could. I would use a dutch oven on the stove and do the first part with the sauteeing then add the liquid and lentils and simmer until lentils are cooked through…it’ll probably take 20 minutes or so
