Ingredient checklist

Use the ingredient names and amounts exactly as listed below for best results.

▢ 1 1/2 – 2lbs (750g-1kg) chicken thighs, or chicken breasts
▢ salt
▢ ground black pepper
▢ 1 tablespoon olive oil
▢ 3 cloves garlic, minced
▢ 6 oz (175g) cremini mushrooms, or white mushrooms, stems trimmed
▢ 1/2 cup chicken broth
▢ 1/2 cup whipping cream, or heavy whipping cream
▢ 1/4 teaspoon salt, or to taste
▢ 3 dashes cayenne pepper
▢ 1 tablespoon lemon juice
▢ 1 tablespoon chopped parsley

Notes on ingredients and swaps

Chicken thighs are my go-to: they stay moist and tolerate the Instant Pot’s heat well. If you use chicken breasts, check texture carefully—breasts can dry out faster but still work. Cremini mushrooms bring a deeper, earthier flavor; white mushrooms are a fine substitute and will make the sauce a touch lighter in color. Use the specified amounts exactly for consistent results.

Equipment

Instant Pot or similar electric pressure cooker
Spoon or tongs for flipping the chicken
Measuring cups and spoons
Small bowl for mixing the finishing ingredients

Step-by-step directions

The directions below are rewritten and clarified step-by-step to match the ingredient list and to make the process straightforward.

Prepare the chicken: Pat 1 1/2 – 2lbs (750g-1kg) chicken thighs or chicken breasts dry with paper towels. Season both sides evenly with salt and ground black pepper. Place the chicken pieces on a plate while you prepare the other ingredients.
Set up the Instant Pot: Turn the Instant Pot to the “Sauté” setting and allow it to heat. When the display shows “Hot,” pour in 1 tablespoon olive oil and swirl to coat the bottom of the inner pot.
Sear the chicken: Working in batches if necessary to avoid crowding, add the seasoned chicken pieces to the hot oil. Sear each piece for about 2–3 minutes per side, until both sides develop a golden-brown color. Use tongs to flip the chicken gently. You do not need the chicken to be fully cooked at this stage—just browned.
Remove and set aside: Transfer the seared chicken to a clean plate and set aside while you cook the aromatics and mushrooms.
Sauté the garlic: Add the minced garlic (3 cloves) to the Instant Pot and sauté for about 30 seconds to 1 minute, stirring constantly. Watch carefully so the garlic does not burn; it should become fragrant.
Cook the mushrooms: Add 6 oz (175g) cremini mushrooms (or white mushrooms), stems trimmed, directly into the pot with the garlic. Sauté the mushrooms for 3–4 minutes, stirring occasionally, until they release some of their liquid and begin to brown around the edges.
Deglaze with broth: Pour in 1/2 cup chicken broth and use a wooden spoon or spatula to scrape up any browned bits from the bottom of the pot. These bits add flavor and help prevent a burn notice. Make sure the bottom is clean of stuck-on food before proceeding.
Return the chicken to the pot: Nestle the seared chicken pieces back into the Instant Pot on top of the mushrooms and garlic. Arrange them in a single layer as much as possible so they cook evenly.
Pressure cook the chicken: Close the Instant Pot lid and set the valve to the sealing position. Select the pressure cooking function and set it to cook at High pressure. For chicken thighs, set the cook time for 8 minutes. For chicken breasts, set the cook time for 7 minutes. Once the time finishes, allow the pressure to release naturally for 5 minutes, then carefully perform a quick release to release any remaining pressure. When the pin drops, open the lid.
Prepare the cream finishing mixture: While the chicken rests for a moment in the hot pot, stir together 1/2 cup whipping cream (or heavy whipping cream), 1/4 teaspoon salt (or to taste), 3 dashes cayenne pepper, and 1 tablespoon lemon juice in a small bowl. Mix until uniform.
Thicken and finish the sauce: Switch the Instant Pot back to the “Sauté” setting and reduce the sauce gently for 1–2 minutes if it looks watery. Pour the cream mixture into the pot and stir to combine. Allow the sauce to simmer for 2–3 minutes, stirring frequently, until the sauce thickens slightly and becomes glossy. Taste and adjust seasoning with additional salt or black pepper as desired.
Add the parsley and serve: Stir in 1 tablespoon chopped parsley just before serving. Spoon the creamy garlic mushroom sauce over the chicken and serve immediately with your preferred side—rice, pasta, or potatoes all make excellent choices.

Troubleshooting and tips

If you get a “burn” notice on the Instant Pot, stop, remove the lid, and scrape the bottom of the pot to free any stuck-on bits. Add a splash more chicken broth, then reseal and continue.
To deepen flavor, sear the chicken a bit longer at step 3—an extra minute per side will yield a richer fond to deglaze.
For a thicker sauce, simmer a few minutes longer on “Sauté,” or remove a few tablespoons of the sauce, whisk it with a small amount of cream or cornstarch slurry, then stir it back in and simmer until thickened.
If you prefer a brighter lemon flavor, add an extra 1/2 teaspoon lemon juice at the end and taste again before serving.

Serving suggestions

This Creamy Garlic Mushroom Chicken (Instant Pot) shines over:

Buttery mashed potatoes to soak up every drop of sauce.
A bed of fluffy long-grain rice or creamy risotto for an elegant plate.
Fresh pasta tossed in the sauce with a sprinkle of grated Parmesan and cracked black pepper.
Steamed vegetables or a crisp green salad to balance the richness.

Make-ahead and storage

Leftovers keep well: cool completely, transfer to an airtight container, and refrigerate for up to 3 days. Reheat gently on the stove over low heat, stirring frequently, or in short bursts in the microwave so the cream doesn’t separate. If the sauce looks a bit thick after chilling, stir in a splash of chicken broth or water while reheating to loosen it.

Final thoughts

This Creamy Garlic Mushroom Chicken (Instant Pot) is a weeknight champion: minimal hands-on time, bold flavor, and a comforting sauce that dresses up any simple side. Follow the steps in order, use the ingredient amounts listed, and the Instant Pot will reward you with juicy chicken and a luscious mushroom-cream sauce every time.

Happy cooking—enjoy a cozy, satisfying dinner tonight!

ground black pepper to taste
1 tablespoon olive oil divided (use 1/2 tbsp to sear and remaining for sauce)
3 cloves garlic minced
6 oz cremini or white mushrooms 175 g, stems trimmed
1/2 cup chicken broth
1/2 cup whipping cream or heavy whipping cream

3 dashes cayenne pepper
1 tablespoon lemon juice
1 tablespoon parsley chopped

Equipment

Instant Pot or electric pressure cooker
Tongs or spatula

Knife and cutting board
Wooden spoon or silicone spatula

Method

Rinse the chicken and pat dry with paper towels. Trim excess skin and fat, then season both sides with salt and ground black pepper; set aside.
Set the Instant Pot to Sauté and let it heat. Add 1/2 tablespoon olive oil.
Sear the chicken in the pot, skin-side down first, until browned on both sides; remove and set aside. Spoon out and discard excess rendered fat if needed.
Add the remaining olive oil to the pot, then sauté the minced garlic briefly until fragrant (about 30 seconds).
Add the mushrooms and pour in the chicken broth, scraping any browned bits from the bottom.
Return the seared chicken to the pot. Stir in the whipping cream, 1/4 teaspoon salt (or to taste), and cayenne pepper.
Close the lid, set the valve to sealing, select Manual/High Pressure, and cook for 10 minutes.
When the cook time ends, perform a quick release. Once the valve drops, remove the lid and stir in the lemon juice and chopped parsley.
Switch to Sauté mode and simmer a few minutes to reduce and thicken the sauce if desired; adjust seasoning with more salt or lemon juice to taste.
Serve immediately, for example over plain spaghetti if desired.

Notes

I used a 6-quart Instant Pot.
If using frozen chicken, increase pressure cooking time by 10 minutes.
You can add the whipping cream after pressure cooking if preferred.
If you don't have an Instant Pot, pan-fry the chicken and simmer the sauce on the stovetop until cooked through.
