Turn Instant Pot on to sauté setting. Once hot, add the ground beef and break it up/stir to begin browning. Add the onion, garlic powder, salt and pepper. Cook, stirring frequently, until the beef is browned, about 5 minutes. Add Worcestershire sauce and stir.
1 pound ground beef, 1 medium onion, ½ teaspoon garlic powder, ¼ teaspoon salt, ¼ teaspoon black pepper, 2 teaspoons Worcestershire sauce
Add the beef broth and stir to ensure nothing is sticking to the bottom of the pot, then turn off the sauté setting.
¾ cup beef broth
Layer the green beans and corn on top of the meat, then layer the condensed soup on top. Do not stir.
12 ounces cut green beans, 1 cup corn, 10 ounce can cream of mushroom soup
Place the lid on the Instant pot and seal. Set the cycle to cook on high for 4 minutes. When the cycle is done, manually release the pressure, then remove the lid.
Add sour cream and half the cheese, then stir to incorporate.
¼ cup sour cream, 1-2 cups shredded cheese
Layer the frozen tater tots on top of the casserole mixture and sprinkle with the rest of the cheese.
16 ounces Tater Tots
Place Air Fryer Lid on top of the Instant pot and set cooking cycle to 10 minutes at 400F. No need to turn the food when the lid signals to do so.
Once air fryer cycle is complete, the casserole is ready to serve!
Notes
If you do not have an Air Fryer Lid, simply heat the tots using your oven or any other brand of air fryer, then add to the top of the cooked mixture and sprinkle with cheese.
