Recipe Information
Ingredients
- 1 tablespoon olive oil
- 1 medium onion, diced
- 2 cloves garlic, minced
- 3 cups mixed frozen vegetables (e.g., peas, carrots, corn, and green beans)
- 8 ounces baby bella mushrooms, sliced
- 1 can (10.5 ounces) cream of mushroom soup (vegetarian)
- 1 cup sour cream
- 2 cups shredded cheddar cheese
- 32 ounces tater tots (frozen, uncooked)
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 0.5 teaspoon dried thyme
- 0.25 teaspoon paprika (optional, for garnish)
Instructions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set aside.
Heat olive oil in a large skillet over medium heat. Add the diced onion and cook for 3-4 minutes until softened.
Stir in the minced garlic and cook for an additional 30 seconds until fragrant.
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.
Transfer the vegetable mixture to the prepared baking dish. Spread evenly across the dish.
Sprinkle 1 cup of shredded cheddar cheese over the vegetable mixture.
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.
Remove from the oven and sprinkle the remaining shredded cheddar cheese on top. If desired, garnish with a pinch of paprika.
Return to the oven for an additional 5 minutes, or until the cheese has melted.
Let the casserole cool for 5 minutes before serving. Enjoy your Easy Vegetarian Tater Tot Casserole!
