Directions

Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set aside.

Add the sliced mushrooms to the skillet and cook for 5-7 minutes until softened and most of the liquid has evaporated.

Mix in the frozen vegetables, cream of mushroom soup, sour cream, salt, black pepper, and dried thyme. Stir well to combine and allow the mixture to heat through for 2-3 minutes.

Step 6

Transfer the vegetable mixture to the prepared baking dish. Spread evenly across the dish.

Step 7

Sprinkle 1 cup of shredded cheddar cheese over the vegetable mixture.

Step 8

Arrange the frozen tater tots in a single layer on top of the cheese.

Bake in the preheated oven for 30-35 minutes, or until the tater tots are golden and crispy.
