Easiest Instant Pot Vegan Pasta

The answer to “What time is it?” is always “pasta time”.

I jumped on the Instant Pot bandwagon in 2016. And I pretty much wanted one to avoid soaking dried beans overnight (because I never remember).

But, beyond that feature, I had no idea what a pressure cooker could or could not do. Eventually, I tried some recipes but for the most part I used it to prep beans, chickpeas and lentils. Making an easy and tasty Vegan Pasta in my Instant Pot certainly never crossed my mind.

Then at a Tollycraft Boating Club event, a Tolly friend made spaghetti bolognese in her Instant Pot for our potluck dinner. And my mind was blown!!!

Making Instant Pot Vegan Pasta on a boat

Now that we live full-time on the boat, my Instant Pot One-Pot Veggie Pasta is one of my go-tos. Why?

  1. It’s perfect when my handsome hubby is working late as it takes 30 minutes from start to finish.
  2. Some days I really don’t feel like cooking, and this is so easy it keeps us from take-out or the pub (well usually…).
  3. And it’s a great use for vegetables nearing their best before date.

Try this recipe with your favourite marinara sauce, veggies and whatever spices you like. I love adding a Field Roast sausage and I almost always use up the last of my spinach.

Boat Tested and Tasted
