Creamy Mushroom Chicken Skillet
This dairy-free take on creamy mushroom chicken swaps the cream-of-mushroom base for a soaked-cashew sauce, simmered with seared chicken, mushrooms, garlic, and fresh thyme in one skillet.
Why You'll Love This Recipe
If you grew up on creamy mushroom chicken made with canned cream-of-mushroom soup, this version gives you the same savory, blanketed comfort without any dairy. Soaked cashews blend into a pourable cream that clings to seared chicken and mushrooms, while nutritional yeast adds the gentle, cheesy savoriness the dish is known for. Fresh thyme and garlic keep it tasting like a homemade pan sauce rather than something poured from a can.
The chicken breast is what makes a dinner like this feel satisfying and steady, and searing it from raw keeps it tender. The cashews bring a soft richness plus a little healthy fat, and the mushrooms add moisture and an earthy, meaty depth. Nutritional yeast layers in that savory note along with B vitamins, so the sauce tastes rich while staying grounded in real, recognizable ingredients.
The whole dinner comes together in one skillet, which means the browned bits left from searing the chicken become the backbone of your sauce. You sear, set the chicken aside, cook the mushrooms and aromatics in those same drippings, then pour in the blended cashew cream and let everything simmer back together. Cleanup stays simple, and the chicken finishes tender because it rests while the sauce builds its flavor.
Ingredients
- 2 lb boneless skinless chicken breasts (raw)
- 4 cups sliced mushrooms
- 1/2 cup raw cashews, soaked
- 1 onion, diced
- 4 cloves garlic
- 2 tbsp nutritional yeast
- 1 tbsp fresh thyme
- 2 tbsp olive oil
- 1/2 tsp salt
Instructions
- Prep the cashew cream: Soak the raw cashews in hot water for at least 15 minutes, since a soaked cashew blends to silk where a dry one stays gritty, then drain them and blend with the nutritional yeast, a pinch of the salt, and about 3/4 cup fresh water until completely smooth and pourable. Set the cream aside.
- Season and sear the chicken: Pat the raw chicken breasts dry and season both sides with the salt. Heat the olive oil in a large skillet over medium-high, then sear the breasts undisturbed for 4 to 5 minutes per side until golden and cooked to 165°F (74°C) internal. Transfer to a plate.
- Brown the mushrooms: Add the sliced mushrooms to the same skillet in a single layer. Let them sit without stirring for 2 to 3 minutes so they brown, because mushrooms moved early sit in their own water and never color, then stir and cook until the liquid has gone and they are deeply golden, about 6 minutes in total.
- Cook the aromatics: Stir in the diced onion and cook until soft and translucent, about 4 minutes. Add the garlic and fresh thyme and cook for one more minute, until fragrant, scraping up the browned bits from the bottom of the pan.
- Build the sauce: Pour in the blended cashew cream and stir to combine, loosening with a splash of water if it looks thick. Bring it to a gentle simmer and cook for 2 to 3 minutes until it thickens into a silky sauce that coats the mushrooms, keeping it below a boil, since cashew cream tightens and turns grainy over high heat.
- Return and serve: Slide the seared chicken and any resting juices back into the skillet, spooning the mushroom cream over each breast. Warm through for a minute, then serve, giving each plate one breast with a generous ladle of sauce.
Variations
- Boneless thighs: Swap the breasts for boneless, skinless thighs, which stay especially juicy and still reach a safe 165°F (74°C) internal in the sear-and-simmer method.
- Add greens: Stir a few handfuls of spinach or chopped kale into the sauce during the final simmer and let it wilt for extra color and fiber.
- Mixed mushrooms: Use a blend of cremini, shiitake, and oyster mushrooms in place of plain button mushrooms for a deeper, more layered earthy flavor.
- A splash of wine: Deglaze the pan with a quarter cup of dry white wine before adding the onion, letting it cook down to concentrate the pan flavor. Wine is alcohol, so this version is no longer Whole30.
- Herb swap: Trade the thyme for fresh rosemary or sage when you want a woodsier, more autumnal note in the mushroom cream.
Storage & Leftovers
Let the skillet cool, then store the chicken and sauce together in an airtight container in the refrigerator for up to four days. Keeping the breasts submerged in the cashew cream helps them stay moist, so try to spoon extra sauce over the top before you seal the lid.
Cashew sauces freeze better than dairy ones, so you can freeze portions for up to two months. Cool completely, pack into freezer-safe containers, and leave a little headspace. Thaw overnight in the fridge before reheating; the sauce may look separated at first but comes back together with a gentle stir.
Reheat gently over low heat on the stovetop, adding a splash of water or broth to loosen the cashew cream as it warms. Stir often and pull it off the heat as soon as the chicken is hot through, since high heat can make the sauce grainy and overcook the breast.
Notes & Tips
- Soak longer if you can: I like to soak the cashews for a couple of hours when I have time, since a longer soak gives me the smoothest, most pourable cream.
- Blend until silky: Run the blender a full minute and scrape down the sides, because any leftover cashew grit will stay slightly gritty in the finished sauce.
- Give mushrooms room: Spread the mushrooms out and resist stirring at first; crowding them steams the mushrooms instead of browning them, and browning is where the flavor lives.
- Trust a thermometer: I always check the thickest part of the breast for 165°F (74°C) rather than guessing, so the chicken stays juicy without any pink center.
- Dry the chicken first: Patting the breasts dry before searing helps them form a real golden crust instead of sticking or steaming in the pan.
- Even out the thickness: Pound thicker breasts to a more even thickness so they cook through at the same rate and none of the meat dries out.
Nutrition & Mindful Eating
- The chicken, the mushrooms and the cashew cream come together in one pan. The chicken leaves browned bits behind as it sears, the mushrooms give up their liquid and lift those bits back up, and the blended cashews turn all of it into sauce.
- Chicken breast is close-grained and mild, which is exactly what a sauce this savory wants under it, and the protein it carries is what makes the skillet eat like a full dinner.
- Mushrooms are worth crowding into the pan and then leaving alone until they squeak and brown. That browning is where the earthy, almost meaty flavor comes from, and the B vitamins they carry come along with it.
- Soaked cashews blend into a cream that stays smooth over heat and does not split, and the fat they bring is what gives the sauce its weight on the fork.
- Fresh thyme goes in near the end so the leaves stay perfumed rather than stewed, and the onion and garlic underneath have already melted into the sauce by then, sweet and barely there.
- As you eat, the thyme comes up with the steam before anything else does, so let that land first, and give the plate your attention for as long as it takes to finish it.
Frequently Asked Questions
Can I make this nut-free?
Yes. Swap the cashews for raw sunflower seeds or hemp seeds blended the same way, or use an unsweetened dairy-free cooking cream for a similar texture.
What should I serve with it?
The mushroom cream is lovely over mashed cauliflower, rice, or noodles, and a simple green salad or steamed broccoli rounds out the plate.
Can I make it ahead and reheat it?
Absolutely. Cook fully, refrigerate up to four days, and reheat gently over low heat with a splash of water or broth so the cashew cream stays smooth.
How much carbohydrate is in this?
The mushrooms and cashew sauce carry the body of this dish, so the side you serve with it is what rounds out the plate.
