A cozy potluck casserole of mixed vegetables baked in a creamy Swiss cheese sauce under crispy fried onions.
5 steps, about 35 minutes start to finish.
Preheat oven to 350°F.
In a large bowl, combine thawed vegetables, cream of mushroom soup, 1/2 cup Swiss cheese, sour cream, black pepper, pimientos, and 1/2 cup crispy fried onions. Mix until evenly combined.
Pour mixture into a 1-quart casserole dish.
Bake uncovered at 350°F for 30 minutes.
Top with remaining Swiss cheese and remaining crispy fried onions. Bake uncovered for 5 minutes longer, until cheese is melted and onions are golden.
“Make sure to thoroughly drain the thawed vegetables: excess water makes the casserole soupy. The crispy onion and cheese topping goes on at the very end so it stays crunchy.”
