Sweet Potatoes with Thai Peanut Butter Sauce

If you read our last post, you’ll know: Alex and I were very skeptical of the Instant Pot. Anything that’s trendy turns on our skeptic meter, so we avoided anything Instant Pot or electric pressure cooker for years. We finally decided to give it a try when we found a friend who cooked sweet potatoes in it religiously: and turns out it cooks rice and dried beans too. Perhaps it would give our rice cooker a run for its money?

After trying it several times, we found the Instant Pot cooks sweet potatoes in less time than baking and it’s totally hands off. This healthy sweet potatoes recipe with Thai peanut butter sauce is our idea on how to use those Instant Pot sweet potatoes! And don’t worry: if you don’t have any Instant Pot, there’s a baked version as well. Keep reading for the recipe.

How to cook sweet potatoes?

Here’s our method for how to cook sweet potatoes in an Instant Pot! They come out with a moist and velvety interior. If you don’t have a pressure cooker, make our Steamed Sweet Potatoes or Quick Baked Sweet Potato method. (The steamed potatoes are closest in moistness to the Instant Pot method!)

How long to cook sweet potatoes? Our method for Instant Pot sweet potatoes takes 35 minutes total, including preheat time and natural release time. Just throw them in the pot, cook on high pressure for 16 minutes, and natural release for 10 minutes. If you’re baking the sweet potatoes, a tip is to cut them in half, which shortens the cooking time! This way, you can bake them for just 25 to 30 minutes at 400F.

This Thai peanut butter sauce recipe

This recipe is simply Thai inspired: there’s nothing authentic Thai about it! You can make the slaw and Thai peanut butter sauce in the time it takes to cook the sweet potatoes. The slaw and Thai peanut butter sauce are a loose inspiration from the flavors of Thai food: cilantro, lime, soy balanced with a touch of sweet (here maple syrup), green onion, and peanut.

This recipe is vegetarian, and naturally gluten free and vegan (plant based) as well. It’s healthy, colorful, and delicious — we served it to our neighbors and they couldn’t believe how flavorful it was. This one’s also a great Back to School recipe, since school will be starting up in a few weeks!

What are other vegetarian Instant Pot recipes?

Another hangup about the Instant Pot for us was that we thought it was mainly helpful for cooking meat quickly. Since we eat mainly vegetarian on a daily basis, we were interested in vegetarian Instant Pot recipes. This Instant Pot sweet potatoes with Thai peanut butter sauce recipe is one of our favorite Instant Pot vegetarian recipes — here are a few more of our favorites!

  1. I would never have thought to cook sweet potatoes in an Instant Pot, what a great idea! I haven’t got an Instant Pot but I’ve seen so many recipes that use them, I’m definitely tempted.

    I love Thai flavours as well, so this looks great!

  2. This is a super easy recipe and surprisingly packed with flavor! It also took barely any time to prepare and was so healthy, I think this is going to become a staple recipe for my boyfriend and I. I couldn’t get enough of that slaw, I was just sitting there eating the slaw on it’s own afterwards and might just make the slaw without the potatoes in the future ? Thanks for sharing this!

  3. Thanks for a great recipe! Made this meal for dinner tonight and it was super filling, satisfying and delicious! We had a spinach salad topped with some pineapple slices that I roasted alongside the sweet potatoes. This will definitely be added to the “go-to” meal list!

  4. Loved the recipe! I would have never thought to use sweet potato. I added a clove of garlic, knob of ginger and a bit of red curry paste to the peanut sauce and it was amazing.

  5. This was great! I had some lentils in the fridge that I dressed with lime and cilantro to add more protein. I think next time we may actually skip the sweet potato and serve the slaw and sauce over lentils!

  6. I made this today and it was DELICIOUS. I did without the bell peppers because I don’t like them, and it was still amazing. YUM

  7. This was very good. I was serving 2, so I only used 2 sweet potatoes, but I made the full dressing and slaw quantities because of all the replies saying they were so good. We agree. I did make one small modification. Using the recipe for the sauce, it said to “drizzle” it over the slaw, but mine was too thick for that. I added 1 more tablespoon of water and that worked great and didn’t adversely affect the flavor. This recipe is definitely a keeper, and the slaw/sauce combo could easily have other applications. Thanks.

  8. Fed this to my meat-eating family. There were no leftovers. I served it with grilled pineapple. The peanut sauce recipe is no good turning out thick & not sweet enough. Use your favorite peanut sauce. Also, I used 3X the ammount of cilantro.
