Ultimate Instant Pot Beef Stew is made in a fraction of the time a stovetop or slow cooker version would take. Tender beef and veggies, in a hearty sauce!
Add beef chunks to a large bowl, sprinkle flour, salt, and pepper onto it. Stir to combine.
Add the water to the IP to deglaze it, and using a wooden spoon scrape well the bottom of the pot to remove any bits that stuck to it, make sure you scrape it well to avoid burning during cooking.
Next, add the beef back to the pot, followed by chopped carrots, mushrooms, potatoes, and pearl onions if using.
If you want the sauce to be thicker, mix corn starch and water in a small bowl until fully combined.
With the IP on Saute, add the mixture to the pot and gently stir, trying not to crush the veggies. Cook for 2-3 minutes, until the sauce, thickens.
