Chicken Marsala Instant Pot Recipe: Wine-Infused Mushroom Sauce

This Instant Pot method delivers classic chicken marsala with rich, wine-infused flavor in a fraction of the traditional time. The pressure cooker transforms simple ingredients into a deeply savory dish with tender chicken and a velvety mushroom sauce.

By searing the chicken first, you build layers of flavor before pressure cooking locks in moisture. Marsala wine adds its signature sweetness and depth, while mushrooms absorb the liquid to create a luxuriously thick sauce.

The result is fall-off-the-bone chicken in a sauce so restaurant-quality you’ll forget it came from your kitchen. Serve over pasta or mashed potatoes to soak up every last drop of that incredible sauce.

Ready in 30 minutes, this proves gourmet meals don’t require hours.

Ingredients for Chicken Marsala Instant Pot

Rich wine, tender chicken, and velvety mushrooms come together perfectly in this dish.

The chicken is key here—thighs stay juicier than breasts under pressure. Costco has great pre-trimmed ones, or grab bone-in at the regular supermarket and debone yourself (saves money). Marsala wine is non-negotiable for that signature flavor. Trader Joe’s carries a solid dry version for under $10. For mushrooms, creminis have more depth than white buttons, but either works in a pinch.

No Marsala? Dry sherry at a 1:1 ratio is the closest swap. Skip the cream? Stir in 2 tbsp cream cheese at the end for similar richness. Fresh out of thyme? Dried thyme at one-third the amount works, but add it with the flour. The chicken broth can be subbed with water plus bouillon, but the wine flavor will be more pronounced. Baby portobellos can stand in for creminis with no other changes needed.

This sauce thickens as it cools. Leftovers keep 4-5 days in the fridge, but the mushrooms will soak up more liquid—stir in a splash of broth when reheating. Freezes beautifully for 3 months (the cream might separate slightly, but it comes back together). Always serve over something to catch that sauce—pasta, mashed potatoes, or crusty bread.

Step-by-Step Instructions for Chicken Marsala Instant Pot

Here’s the method I swear by for restaurant-quality results without the fuss.

Step 1: Sear the Chicken Thighs

Set your Instant Pot to the Sauté function on normal heat. Add the 1 tbsp olive oil and 1 tbsp unsalted butter and let it melt. Pat the 1.5 lb boneless skinless chicken thighs dry, then season both sides with the 1 tsp kosher salt and 0.5 tsp freshly ground black pepper.

Working in batches if needed, add the chicken to the pot and sear for 3-4 minutes per side until golden brown. The chicken should release easily from the bottom when it’s ready to flip. Transfer the seared chicken to a plate and set aside.

Step 2: Build the Sauce Base

In the same pot, add the remaining 1 tbsp unsalted butter. Once melted, add the 10 oz cremini mushrooms, 1 whole shallot, and 3 cloves garlic cloves. Sauté for 4-5 minutes until the mushrooms release their moisture and begin to turn golden brown.

Stir in the 3 pieces fresh thyme sprigs and 1 tsp Dijon mustard, cooking for an additional 30 seconds until the aroma fills the air. This step ensures the flavors meld beautifully before pressure cooking.

Step 3: Deglaze and Pressure Cook

Pour in the 0.75 cup Marsala wine and use a wooden spoon to scrape up any browned bits from the bottom of the pot. Let it simmer for 2 minutes to reduce slightly. Stir in the 0.5 cup chicken broth, then return the seared chicken to the pot, nestling it into the liquid.

Secure the lid, set the valve to Sealing, and pressure cook on high for 8 minutes. The Instant Pot will take about 10-15 minutes to come to pressure before the timer begins. Once done, allow a natural pressure release for 5 minutes, then quick-release any remaining pressure.

Step 4: Finish with Cream and Thicken

Carefully remove the lid and transfer the chicken to a serving platter. Switch the Instant Pot back to Sauté mode on low. Stir in the 0.5 cup heavy cream and simmer for 3-4 minutes until the sauce thickens slightly.

In a small bowl, whisk the 0.25 cup all-purpose flour with 2 tablespoons of cold water to create a slurry. Stir the slurry into the sauce and cook for an additional 1-2 minutes until it reaches your desired consistency. The sauce should coat the back of a spoon.

Return the chicken to the pot, spooning the sauce over it to coat evenly. Let it warm through for 1-2 minutes before serving.

Make-Ahead Tips for This chicken marsala instant pot

Prep Ahead Strategy

You can prep all ingredients the night before—slice 10 oz cremini mushrooms, mince 1 shallot and 3 garlic cloves, and measure out all wet and dry ingredients. Store them in separate containers in the fridge. This cuts morning prep to just 5 minutes. 💡

Par-Cook Chicken

For even faster assembly, sear the 1.5 lb chicken thighs the night before and refrigerate them in an airtight container. In the morning, just deglaze and pressure cook as usual. The seared crust holds up beautifully overnight.

Sauce Base Shortcut

Make the entire sauce base (mushrooms, shallots, garlic, wine) up to 2 days ahead. Store it in the fridge, then just add chicken and broth when ready to pressure cook. The flavors deepen with time.

Freezer Meal Prep

Combine raw chicken, mushrooms, shallots, and garlic in a freezer bag. Freeze flat for up to 3 months. Thaw overnight in the fridge, then sear and cook as directed. Add wine and broth fresh for best results. ❄️

Reheating Tips

Leftovers keep 4-5 days in the fridge. Reheat gently on the stovetop over low heat with a splash of broth to loosen the sauce. Avoid microwaving, as it can cause the cream to separate.

Serving Suggestions

This dish tastes even better the next day. I love serving it over fettuccine or creamy polenta to soak up that incredible sauce. Garnish with fresh thyme leaves for a restaurant-worthy finish.
