Preheat your oven to 425°F (220°C) and lightly grease a baking sheet with non-stick cooking spray.

Spread the frozen tater tots evenly on the baking sheet and bake according to package instructions, typically about 20-25 minutes, until golden and crispy.

While the tater tots are baking, cook the bacon until crispy if not already prepared, then crumble into small pieces.

Remove the tater tots from the oven and arrange them closely together in a single layer on the baking sheet.

Sprinkle the shredded cheddar cheese evenly over the tater tots, followed by the crumbled bacon.

Return the baking sheet to the oven and bake for an additional 5-7 minutes, or until the cheese is melted and bubbly.

Carefully remove the tater tots from the oven and let them cool slightly before topping with dollops of sour cream and a sprinkle of chopped green onions.

Serve warm and enjoy your loaded tater tot appetizers!
