Instant Pot Paleo Cauliflower Mushroom Risotto

Ever since I started learning about how therapeutic and healing mushrooms can be, I’ve been trying to incorporate it more and more into my diet. Mushrooms are high in vitamins, minerals, and antioxidants, and they are known for their cancer-fighting properties, as well as their ability to boost immunity. With the sudden change in temperature, I’m all about getting that immune boost and nutrient density in any form.

I’ve always loved risotto. It’s always the one thing in Italian restaurants that I can count on because it is naturally gluten free since it’s made of rice. However, I feel my best when I eat lower in carbs so I took on the challenge of making a Whole30-friendly and grain-free version, and I’m happy to report that this Cauliflower Mushroom Risotto turned out fantastic.

    Risotto used to be one of my favorite things back in my 17 years of vegetarian turned vegan days. I practically lived on it. This was before I knew grains are not so great for my body. I am SO excited about your version and can’t wait to try it! I love that you make this in the Instant Pot too, my favorite kitchen tool 🙂

    Hello, I am nervous about using the yeast in this recipe due to my autoimmune condition. What does the yeast do for this recipe? And how would it turn out without it?

    1. Jean Choi Post author

      Nutritional yeast isn’t really like other yeast. It gives a cheesy flavor to the recipe. You can make this recipe without it if it bothers you.

    Mushroom risotto was always one of my all time favourite dinners – love the look of this, am adding it to my list of things to make. Those photos also make me feel hungry!

    Can you use a different thickener other than tapioca starch? Like I have potato starch and arrowroot. Would either of these work? I just have them on hand is all

    I don’t remember how I stumbled on your recipe; but that doesn’t matter. I made it tonight and first, it’s so simple! I used Trader Joe’s cauliflower rice since I already had the bag in the freezer. When I opened the IP after cooking, it smelled like the real deal. Then I tasted it and oh my god!! It tastes like the real deal, too! Next time I may swap in truffle salt in lieu of plain sea salt.

      Thanks so much, Shaina. Makes me so happy that you enjoyed the recipe. And I may steal your truffle salt idea. That sounds awesome!

    2. ChapelHillBetsy

      I was going to ask if we could use frozen or fresh cauli rice. I have both. Can’t wait to make this recipe!

      I use TJ’s cauliflower rice too. The fresh one in the produce section. How many bags did you use for this recipe?

  6. ChapelHillBetsy

    Well I made this for lunch today. Only difference is I added some parmesan cheese before serving it. IT.WAS.AMAZING! I didn’t tell my husband it was made with cauliflower – he thought it was made the traditional way with rice. He raved about it! Thanks!

    I didn’t have many of these ingredients, so I had to modify quite a bit. Even so, this recipe turned out wonderfully well and so delicious! I only had 8 oz. of mushrooms, so I added 8 oz. canned chickpeas to make a pound. Instead of coconut aminos, I used soy sauce. I suffer from iron overload, so I added tea in place of the broth. No nutritional yeast — in place of that, I used parmesan cheese. Finally, I substituted wheat flour for the tapioca starch. Although it sounds as though I substituted this recipe to death, it just goes to show that a solid foundation makes all the difference. This recipe works even with all the modifications, and that means it’s a keeper!

    Do you have a recommendation for making this without an instapot? I don’t have one yet, but this sounds amazing.

    1. Jean Choi Post author

      I’ve never tried but you can saute the mushrooms and veggies on the stovetop, and then for the IP part, simmer everything in a saucepan over medium heat around 10 minutes or so. Once most of the liquid is absorbed, add tapioca starch to thicken. Let me know how it turns out!

  9. ChapelHillBetsy

    I was wondering if you have the nutritional breakdown of this recipe, specifically carbs. I’m on a low carb way of eating.

    LOVED this recipe! Mine came out with a little too much liquid, so I added some cornstarch to thicken it up a bit- worked well! I subbed almond flour for tapioca starch, used 1 bag of frozen TJs cauliflower rice, and a bag of frozen TJs mushroom medley. I think next time I’ll try less broth or add more cauliflower rice!

    1. Jean Choi Post author

      So glad you enjoyed it! Tapioca starch also absorbs more liquid than almond flour so that could be it. Thank you so much for trying it out!

  11. Allyson

    I too found there to be a lot of extra liquid after cooking. I used a ladle to take out the extra and used the starch to thicken which worked. If using homemade cauliflower rice, would you recommend drying out the cauliflower first to avoid this in the future?

    1. Jean Choi Post author

      I think moisture level of the cauliflower varies a lot. I didn’t find much liquid with mine. You can try drying it out, or just remove the extra liquid like you did.

    This tastes amazing! We added some shredded parmesan and it took it to the next level!!

    Thank you!
