Ingredients
  

  • 2 tablespoons butter
  • 2 tablespoons olive oil
  • 2-3 medium yellow onions thinly sliced
  • 1 cup dry white wine divided
  • 1 pound ground beef
  • 2 cloves garlic minced
  • 16 oz mixed frozen veggies thawed
  • 2 teaspoons dried thyme
  • 2 teaspoons dried parsley
  • 2 tablespoons flour
  • 1/4 cup soy sauce
  • 1 tablespoon Worcestershire sauce
  • 1/4 teaspoon cayenne pepper
  • 1 cup water
  • 1 cup shredded Gruyere cheese
  • 2 pounds frozen tater tots
  • 1 cup shredded cheddar cheese
  • fresh chives for topping, optional
  • salt and pepper to taste

Instructions
 

  • Preheat oven to 425°F.
  • In a large oven-safe skillet, melt butter and olive oil with onions. Cook about 5 minutes until softened.
  • Add half of the white wine a little at a time and cook for 8–10 minutes until onions are caramelized.
  • Push onions to one side of the skillet and add ground beef, veggies, garlic, thyme, parsley, salt, pepper, and cayenne. Cook 5 minutes, breaking up the meat as it browns.
  • Stir in flour and cook for 1 minute. Add the remaining wine, soy sauce, Worcestershire, and water. Bring to a simmer and cook 3–5 minutes until thickened.
  • Remove from heat and sprinkle with Gruyere cheese. Top with an even layer of frozen tater tots.
  • Bake for 20 minutes until tater tots are golden. Remove and sprinkle with cheddar cheese. Return to oven and bake 10–15 more minutes until cheese is melted.
  • Top with fresh chives if desired and serve hot.

Notes

You can use a cast iron skillet or transfer everything to a 9x13 baking dish before topping with tater tots if you don’t have an oven-safe skillet. Add a splash more wine or broth if you prefer a saucier filling.
