Heat a cast iron skillet over medium high heat and add the chicken thighs. Brown on both sides, about 3 minutes per side, until skin is crisp and browned.
OPTION: Brown the chicken right in the Instant Pot. You'll want a non-stick insert for this though. Remove the thighs when done cooking and set aside.
Heat the olive oil in the pot on the sauté setting and add the onions and garlic.
Add the mushrooms and cook 2-3 minutes, until they start to release some liquid.
Add the brandy and cook 1-2 minutes, until liquid has cooked down.
Add all remaining ingredients (except cream and crumbled bacon) and set to cook on high pressure for 15 minutes.
Once done cooking, let the pressure release naturally for 10 minutes. Then use the quick release to release the remaining pressure..
Turn the Instant Pot back to the saute setting (normal) and bring to a simmer.
Add the cream and simmer for 5-10 minutes, until sauce is reduced to desired level. Sauce can be thickened with a cornstarch slurry if desired - see expert tips.
Season with additional salt to taste (optional), stir in bacon crumbles and serve over egg noodles (can also be served over mashed potatoes, polenta, spaghetti, etc.).
Notes
Brown the chicken thighs in a cast iron skillet or nonstick pan before them in the Instant Pot for the best results.
After it's done pressure cooking, simmer the chicken with the cream until it's been reduced to a creamy sauce.
If your sauce is too thin, you can thicken it with a cornstarch slurry. Add 2 teaspoons of cornstarch with 1 tablespoon of water and stir to combine. Slowly add the slurry to the instant pot, stirring until the desired thickness is reached.
Season with additional salt and pepper to taste if necessary.
