A quick and easy green bean casserole with homemade crispy fried onions, creamy sauce, and tender green beans. Perfect for weeknights or holidays.
For the best texture, dry the blanched green beans thoroughly to avoid a watery sauce. The fried onions can be made up to 2 days ahead and stored at room temperature; re-crisp in a 350°F oven for 3-4 minutes before adding to the casserole. For a gluten-free version, use gluten-free all-purpose flour and gluten-free cream of mushroom soup. For dairy-free, use unsweetened oat milk and a dairy-free buttermilk substitute.
