1 teaspoon Worcestershire sauce, or about 2 dashes
2 ½ cups frozen mixed vegetables, such as peas, carrots, corn, and green beans
1 pound frozen tater tots
¼ cup finely chopped parsley, for serving
Directions
Preheat the oven to 425 F.
In a cast-iron or oven-proof skillet, heat the oil over medium heat. Add the beef and cook, using a wooden spoon to crumble up the meat, until browned. Drain the grease.
Add the onions and garlic to the beef and cook until soft and fragrant.
Stir the tomato paste into the meat mixture. Once it begins to stick to the bottom of the skillet, add the red wine and stir, scraping up any browned bits off the skillet. Bring to a simmer and reduce until the liquid has mostly evaporated.
Add the beef broth, salt, pepper, fresh herbs, and Worcestershire sauce, and stir to combine. Stir in the frozen vegetables and bring the mixture to a simmer. Simmer until liquid is reduced slightly, about 10 minutes.
Once the mixture is thick enough to support the tater tot layer, turn off the heat and add the tots in a straight line across the skillet, working your way down to the other end. With the tater tots covering the casserole in an even layer, place the skillet in the oven and bake until the tots are golden brown and crispy, about 25 minutes.
Remove the casserole from the oven, sprinkle with parsley, and serve.
