One Skillet French Onion Tater Tot Casserole

Preheat the oven to 425 degrees F.In a large oven safe skillet, melt the butter, olive oil, and onions together. Cook, stirring occasionally until softened, about 5 minutes. At this point, you want to slowly add 1/2 cup of the wine, 1/4 cup at a time, until the wine cooks into the onions. Continue to cook another 8-10 minutes until you've used the 1/2 cup of wine and the onions are deeply caramelized. Push the onions to the side of the pan and stir in the meat, bell pepper, garlic, thyme, parsley, cayenne, and season with salt and pepper. Cook, breaking up the meat as it cooks, another 5 minutes until the meat is browned. Stir in the flour and cook another minute. Add the remaining 1/2 cup wine, soy sauce, Worcestershire sauce, and 1 cup of water. Bring to a boil and simmer until thickened 3-5 minutes. Remove from the heat and sprinkle the Gruyere cheese overtop the meat. Arrange the tater tots on top of the cheese. Transfer to the oven and bake 20 minutes, until the tots are golden. Sprinkle the cheddar over the tater tots, return to the oven. Bake another 10-15 minutes, until the cheese is melted.Serve topped as desired with fresh thyme and chives.
