A quick and easy green bean casserole that comes together in under 30 minutes, featuring tender green beans, a creamy mushroom sauce, and crispy shallots. Perfect for busy weeknights or holiday dinners.
For best results, use regular condensed cream of mushroom soup (not low-fat). The crispy shallots can be made up to 3 days in advance and stored in an airtight container at room temperature. To make ahead, assemble the casserole (without shallots) up to 24 hours in advance and refrigerate; add 10 minutes to baking time. The casserole tastes even better the next day.
