1-Getting this Shepherds Pie Tater Tot Casserole just right involves a few straightforward steps that even beginners can master. Start by preheating your oven to 400 degrees Fahrenheit and spraying a 9×13 baking dish with cooking spray for easy cleanup. This simple prep sets the stage for a smooth cooking process.

2-In a large skillet over medium-high heat, cook and crumble 1 lb of ground beef until it’s no longer pink, which takes about 6-8 minutes. Once done, add 1 finely diced yellow onion and 2 cloves of minced garlic, cooking until the onions are soft and translucent, around 5 minutes; remember to drain any excess fat to keep the dish lighter.

3-Next, stir in 2 cups of frozen mixed peas and carrots, 1 cup of beef broth, 2 tablespoons of Worcestershire sauce, 1 teaspoon of dried thyme, 1 teaspoon of kosher salt, and 1/4 teaspoon of black pepper. Bring this mixture to a simmer, then sprinkle in 2 tablespoons of all-purpose flour, stirring well to thicken it over 1-2 minutes. This step ensures a hearty base for your casserole.

4-Transfer the mixture evenly into your prepared baking dish and arrange 1 bag (32 oz) of frozen potato tots in a single layer on top. Sprinkle 1 1/2 cups of shredded cheddar cheese evenly over everything, then bake for 30-35 minutes until the tots are golden and crispy, and the cheese is melted and bubbly. Let it cool for 5-10 minutes before serving to allow flavors to settle.
