Tater Tot Casserole layers seasoned ground beef, a creamy sauce, and cheese under crispy golden tots. A hearty weeknight dinner the whole family loves.
Place a large oven-safe cast iron skillet over medium heat and add the olive oil, chopped onion, and redpepper. Saute until onions are just translucent, about 4 minutes. Add the garlic and freshthyme and stir for 30 seconds. Remove to a bowl and set aside.
Add the groundbeef to the skillet and cook until browned and no longer pink inside, about 6 minutes.
Add the vegetables back to the skillet and sprinkle everything with flour. Add the chickenstock, worcestershiresauce, and soysauce. Stir well to combine and cook until the liquid mixture becomes slightly thick and bubbly. Stir in 1/2 of the cheese just to incorporate. Remove from the heat.
Arrange tatertots or tater coins on the top and bake for 16-18 minutes, until the mixture is bubbling and the tater coins are brown. Sprinkle with remaining cheese and bake for another 5 minutes, until the cheese melts. Remove and sprinkle with chives, if using, and serve immediately.
