Lentil Spaghetti in Instant Pot?

If you are thinking why Spaghetti in Instant Pot? Let us explain. If you think Instant Pot or pressure cookers are best for food with tough textures why make pasta in Instant Pot when it's already so simple to make it on the stove top. Well you are mistake here, my dear.  Instant Pot Spaghetti is way easier, faster, tastier and hassle free when made in the Instant Pot.

Honestly it's a one pot recipe. No washing and cleaning multiple pots and pans, isn't that golden? No continuous stirring or waiting for the water to boil. Just sautee the onion and garlic and toss in the remaining ingredients and the lentil spaghetti will be ready in 10 minutes. Best part unlike the traditional spaghetti where the spaghetti has to be boiled separately and then mixed in with the sauce. In the Instant Pot the Spaghetti is cooked along with the sauce which packs a lot of flavors into the Spaghetti. It's just a must-try.

If you are worried about gummy sticky noodles or uncooked lentils, don't be!!!Check out the video recipe, you can see how well the noodles and lentils are cooking without sticking to the bottom or burning. I don't know about you but I am never go back to making Spaghetti the traditional way. This is so much easier and tastier. Try it yourself.

How to make Lentil Spaghetti on Stove Top?

If you don't have an Instant Pot and would like to make this recipe, use cooked lentils for this recipe. Cook the spaghetti as per the instructions on the package.In a pan heat oil, sautee the garlic and onion, until it's fragrant then add tomato or our homemade marinara sauce, cooked lentils, salt and cooked spaghetti noodles and allow to cook for a couple mins. Garnish with parsley and serve it hot.

What Lentils can I pair with Instant Pot Spaghetti?

You can make this spaghetti with either, green, brown or even red lentils. The lentils and gluten-free spaghetti take the same amount of time to cook, 10 minutes so there can't be a better match than this. I personally haven't tried using red or brown lentils for this recipe, but typically when I want the lentil texture to be soft like for soups I cook my lentils for upto 8-10 minutes.

What can you serve with this Lentil Spaghetti?

  • Salad
  • Breadsticks
  • Roasted Vegetables

Packing Spaghetti for Lunch

We use a Thermos Lunch box that keeps food warm. We have a few different ones at home that we use. Thermos FuntainerVaya Tyffin, Stainless steel lunchbox with insulated bag.

Freezing or Left Overs

If you have left overs or would like to make some extra and freeze it. Divide it into the portions you want. Place individual portions of Spaghetti into freezer safe zip lock bags. The morning you want to pack Spaghetti for lunch, run warm water on then ziplock for 15 seconds. This will help separate the sides from the bags. Then toss the portion into a microwave safe container add a couple tablespoons of water and reheat in microwave. Adding water will prevent the spaghetti from drying.

Missing in recipe: how many teaspoons of Italian season??

Joy Beach Thomas

Thursday 2nd of April 2020

I have a question. How can I change the recipe for four people? I worry that doubling it might cause issues, because it's perfect as it is for two people.

Made this last night, but with whole wheat spaghetti instead of gluten free. The Ingredients list (which I used to shop) didn't reference Italian Seasoning, so I had no idea how much to use - so I didn't use any, thinking it was a mistake.

The written directions didn't mention when to add the garlic, onion or lentils. I didn't watch the video and was working off a print out. I ended up putting my lentils on top of my pasta, but I did swoosh things around to get most of the pasta off the bottom. Still somehow this novice in the kitchen managed to succeed in turning out an excellent meal with no burns.

I also added extra sauce when I put it into my containers. But I like extra sauce.

I would make this again, but might scope around for another recipe which provides quantities for all ingredients and/or mark up my print out with my lessons learned for next time.

Thanks!

I enjoyed this. Double the recipe fed the four of us with a side salad. We all agreed that we could adapt it with extra veggies or olives.
