Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking and make clean-up easier.

Step 2: Cook the Beef and Onions

In a large skillet over medium heat, cook the ground beef and diced onion until the meat is browned and the onions are translucent. Drain excess grease.

Step 3: Mix in Vegetables and Sauce

To the cooked beef and onion, add the frozen mixed vegetables, cream of mushroom soup, sour cream, and half of the shredded cheddar cheese. Stir until everything is evenly combined. Season with salt, pepper, and a pinch of garlic powder or paprika if using.

Step 4: Assemble the Casserole

Transfer the beef mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining cheese over the top, then layer the tater tots in a single layer to cover the entire surface.

Step 5: Bake

Place the dish in the preheated oven and bake uncovered for 35–40 minutes, or until the tater tots are golden and crispy and the casserole is bubbly.

Step 6: Serve and Enjoy

Let the casserole sit for 5 minutes before serving. Optionally garnish with sliced green onions for a pop of color and extra flavor.
