These stuffed mushrooms flip the classic green bean casserole into a handheld bite, with a creamy filling and crunchy fried onion topping. Perfect for picky eaters and family dinners.
For best results, choose mushroom caps about 2 inches wide. To prevent watery mushrooms, brush with oil and bake empty for 5 minutes before stuffing. The filling can be made up to 2 days ahead. For extra crunch, broil the topping for 1-2 minutes at the end, but watch closely to avoid burning.
