I recently shared three Budget-Friendly Easy Vegan Instant Pot recipes over on Youtube, and one of them is for Vegan Instant Pot Peanut Butter Banana Oatmeal. It couldn’t be easier and is a great way to get breakfast on the table with minimal work.

This vegan Instant Pot oatmeal recipe is not only budget-friendly but also incredibly easy to make. All you need to do is toss four ingredients (plus water and salt) into the Instant Pot. Set the Instant Pot to the pressure cook setting, and you’ll come back to creamy, delicious oatmeal.

I always use steel-cut oats for the Instant Pot because they get nice and creamy but retain a chewy bite (rolled oats get mushy in the Instant Pot; and definitely steer clear of quick cooking oats). Like most of my dried goods, I buy my oats in bulk to save money. The only thing to remember is you need to grease the inner pot a bit with some oil or cooking spray when cooking oats in the Instant Pot. Otherwise, oats have a tendency to stick to the bottom of the pot and trigger that burn function.

In addition to being budget-friendly and easy to make, this oatmeal is also really wholesome! It has slow-digesting fiber from oats, healthy fats to keep you satiated from the peanut butter and light coconut milk, and is completely free of added sugars. The only source of sugar comes from the bananas.

This Vegan Instant Pot Peanut Butter Banana Oatmeal is also a great option for meal prep because the leftovers will stay good in the fridge for several days!

Keyword: gluten-free, instant pot, oatmeal, peanut butter, refined sugar free, soy-free, vegan
Serving size: 4


  • 1 cup steel-cut oats (certified gluten-free if needed)
  • 1 (13.5 ounce) can “lite” coconut milk, or equivalent amount of oat milk, cashew milk, or soy milk
  • 1 1/4 cups water
  • Pinch of sea salt
  • ½ teaspoon ground cinnamon
  • 2 medium ripe bananas, mashed
  • 3 tablespoons natural, no-sugar-added peanut butter


  • Coat the inner pot of the Instant Pot with cooking spray or oil to prevent the oats from sticking to the bottom. Then add the oats, coconut milk, water, salt, and cinnamon to the Instant Pot and stir well. Scoop the mashed bananas on top of the oat mixture, but don’t stir in.
  • Secure the lid and set the Pressure Release to Sealing. Select the Pressure Cook setting at high pressure and set the cook time to 12 minutes.
  • Once the 12-minute timer has completed and beeps, allow a natural pressure release for 20 minutes and then switch the Pressure Release knob from Sealing to Venting to release any remaining steam.
  • Open the pot and stir the oatmeal thoroughly. There may be some liquid or foam on top, but once you stir it, the liquid will incorporate into the oatmeal and thicken up.
  • Stir in the peanut butter and serve warm. Once cool, store leftovers in an airtight container in the fridge for up to 5 days.

    Hi Nisha,
    Thanks for sharing. I love your recipes! I’m having some trouble with this one because it triggers the burn warning in the instant pot, even when I spray oil in the pot. Any advice?

    1. Nisha

      Hi Louis,

      Sorry to hear that! The burn error is certainly annoying.

      What I’m coming to learn is that there must be some subtle yet significant differences in (1) instant pot models and (2) the thickness of certain ingredients, dependent on brand. I have plenty of people who’ve made certain recipes without a hitch, and then a few who have trouble with those same recipes. For instance, some brands of plant milks, nut butters, etc. might be more viscous/thick than others.

      So, for oatmeal, I’d recommend using a bit more water than the recipe calls for so that the oats are less likely to stick (they’re more likely to stick when mixed with a thick liquid).

    Nisha, I stumbled across you on youtube…and now I’ve bought your cookbook on my kindle and I’ve been trying all your recipes. I’m not a vegan (yet), but you make it easy for me to see myself one day heading down that road. I mostly eat fish and chicken, but I’ve been looking for a way to incorporate more veggies in my diet and you have made it so easy! This recipe is no different. My instant pot was still dirty from last night, but I made this in my rice cooker and it tastes amazing! Thank you for sharing your delicious and nutritious noms with the world!

    Hi there! Awesome recipe, so delicious! I also have some quick or rolled oats at home, what time would you suggest for the instant pot? I would assume a bit less for the quick oats ..
    Thank you so much for your blog and video! Really good job ~

      Hi Ophelie! Thank you for your comment and support! I have never tried quick rolled oats in the Instant Pot (since they’re so quick, I just make them on the stove). If you have traditional rolled oats, you can set the cook time to 3 minutes instead!

      Hi Ophelie,

      I just tried it with quick oats ( good old Quaker Oats) and here are some of my modifications / non-vegan faux pas.

      First, I melted butter in my Instantpot…and my oatmeal still stuck.

      I made about 1 cup of quick oats to 1 cup of liquid ratio. I used about 4 oz of coconut cream ( which comes in a can and is thicker and richer than ordinary coconut milk). I measured them both in the same liquid measuring cup ( and gave it a little swish of water to get all the leftover coconut cream)

      I mashed only one banana ( the only one I had on hand) and added some pumpkin-spice spices, salt, and maple syrup.

      I gave it a stir and then I set it on “normal” pressure for 2 mins. It definitely came out creamier than my normal stove stop cooking, which I find always come out sooooo mushy/gloopy. The best part about setting it up was that it was so simple, and while it was cooking, I was able to prep and make my pot of coffee.

      When it was done, I scooped it in a bowl and I topped it with a dollop of Trader Joe’s Chia and Flax Seed peanut butter, along with some TJ’s apricot Preserves.

      Soooo to answer your question – Yes LOL
