Creating your Tater Tot Casserole is straightforward with these simple steps:

1. Preheat the Oven: Set your oven to 375°F (190°C) to prepare for baking.

3. Add Vegetables: Mix in the frozen mixed vegetables and stir until heated through.
4. Combine Ingredients: Add the cream of mushroom soup and mix well. Season with salt, pepper, and any additional spices you prefer.

6. Top with Tater Tots: Position the frozen tater tots over the cheese layer. Arrange them in a single layer to ensure even cooking.
7. Bake: Place the casserole in the oven and bake for 35-40 minutes, or until the tater tots are golden brown and crispy.
8. Serve: Remove from the oven and allow it to cool for a few minutes before serving.
