Combine flour, salt, and pepper in a mixing bowl. Toss the beef cubes in this mixture to coat them.
2 tablespoons white rice flour, ½ teaspoon fine sea salt, ½ teaspoon ground black pepper, 1 pound beef stew meat
Heat the oil in a Dutch oven or an Instant Pot set to Saute. Brown the floured beef cubes in the hot oil.
2 tablespoons avocado oil
Add a little of the broth to the hot Instant Pot and scrape the bits loose from the bottom to deglaze it. This should prevent the burn warning.
4 cups beef broth
Add the remaining broth and all of the other ingredients. Bring to a boil and then simmer for an hour or longer. If using an Instant Pot, set it to cook on high pressure for 20 minutes and then allow for natural release for at least 10 minutes.
1 large yellow onion, 2 large carrots, 1 pound potatoes, 8 ounces mushrooms, 1 14.5-oz can diced tomatoes, 1 teaspoon dried thyme
Before serving, taste your stew for seasoning and add more salt if necessary. The broth you use will determine the saltiness and each time you make this, it might be different.
