WP. They tested it in the 6-quart Instant Pot. This actually sounds really good.
Ingredients
2 tablespoons ghee, avocado oil or another neutral oil
1 small yellow onion (5 ounces), diced
1 1/2 teaspoons fine salt, divided
3 pounds beef stew meat, cut into 1-inch cubes
1/2 teaspoon freshly ground black pepper
8 ounces white button mushrooms, chopped
1/2 cup no-salt-added beef broth, plus more as needed
4 cloves garlic, minced or finely grated
3 tablespoons soy sauce
1/2 teaspoon dried thyme
1/2 cup sour cream
1 tablespoon arrowroot powder or cornstarch
1 tablespoon water
Cooked egg noodles, cauliflower rice, rice or boiled potatoes, for serving
Instructions
1. Set a programmable multicooker (such as an Instant Pot) to SAUTE. Let the pot heat for 2 minutes, then add the ghee or oil, onion and 1/2 teaspoon of the salt and saute until the onion begins to soften, 3 to 4 minutes.
2. Season the beef all over with the remaining salt and the pepper. Working in batches, add the meat to the pot and cook, stirring occasionally, until evenly browned on all sides, about 2 minutes. As each batch browns, transfer it to a clean plate. When all the meat is browned, press the CANCEL button.
3. Return the browned meat and any accumulated juices to the pot and add the mushrooms, broth, garlic, soy sauce, and thyme, and stir until combined. Make sure the steam valve is sealed. Select PRESSURE (HIGH) and set to 20 minutes. (It may take about 5 minutes for the appliance to come to pressure before cooking begins.) Meanwhile, in a small bowl, whisk together the sour cream, arrowroot or cornstarch, and water.
4. After 20 minutes, release the pressure manually by moving the pressure-release handle to vent, covering your hand with a towel or oven mitt. Never put your hands or face near the vent when releasing steam. Stir in the sour cream mixture, return the pot to SAUTE and bring the sauce to a boil. Cook, stirring frequently, until the sauce thickens and is creamy, adding more broth if desired, 2 to 3 minutes. Turn the appliance off and serve over the desired grain or starch.
