A: Yes, absolutely! For a more complex and earthy flavor, the recipe suggests trying a mix of mushrooms like cremini and shiitake. Feel free to use your favorites.
Q: How can I make the flavor even richer
A: For a deeper, more savory flavor, use the SAUTE function on your Instant Pot to brown the chicken thighs and mushrooms before adding the liquids and pressure cooking. This step adds a wonderful depth to the final dish.
Q: Is this Instant Pot chicken recipe keto-friendly

Pro Tips
- Brown the chicken thighs and sliced portabella mushrooms on the Sauté function before adding the liquids and pressure cooking. Those extra few minutes build a deeper, more savory coconut sauce.
- For a lower-carb thickener than arrowroot starch, whisk in a pinch of xanthan gum at the end of the Sauté step. The sauce turns silky without adding carbs.
- No portabellas on hand? A mix of cremini and shiitake mushrooms works just as well and gives the sauce even earthier, more complex notes.
- If you swap in fresh herbs, use 1 tablespoon each of fresh thyme and parsley instead of the 1 teaspoon dried, and stir them in after pressure cooking to keep their bright flavor.
- Leftovers keep in an airtight container in the fridge for up to 3 days. Reheat gently with a splash of water to loosen the thickened sauce.
Frequently Asked Questions
Can I make Instant Pot Chicken and Portabella Mushroom ahead of time?
Yes. Cook it fully, cool it, and store it in an airtight container in the fridge for up to 3 days. The sauce thickens as it sits, so reheat it gently with a splash of water to bring it back to a creamy consistency.
Is this chicken and mushroom dish keto-friendly?
It is. Each serving comes in at 9 g of net carbs with 40 g of protein and 40 g of fat. Serve it over cauliflower rice or zucchini noodles instead of grains to keep the whole plate low-carb.
Can I use a different kind of mushroom?
Absolutely. A mix of cremini and shiitake works beautifully in place of portabella and brings deeper, earthier notes to the sauce. Keep the total around 1 lb / 450 g so the sauce stays balanced.
Can I use fresh herbs instead of dried?
Yes. Use 1 tablespoon each of fresh thyme and parsley in place of the dried herbs, and stir them in after pressure cooking to preserve their bright flavor.
