Fresh Green Bean Casserole (Made From Scratch & Full of Flavor)
Nothing beats a Fresh Green Bean Casserole made from scratch. This classic comfort dish has long been a holiday favorite, but once you try it with fresh green beans instead of canned, it quickly becomes an everyday side dish you’ll crave all year. Crisp-tender beans, a creamy homemade mushroom sauce, and a golden, crunchy topping come together for a casserole that’s rich, satisfying, and far more flavorful than any shortcut version.
As a professional chef, I love this recipe because it balances nostalgia with freshness — perfect for Thanksgiving, family dinners, or special occasions when you want something comforting yet elevated.
Ingredients (Serves 6)
For the Casserole:
- 1½ lbs fresh green beans, trimmed and halved
- 2 tbsp olive oil or butter

- 3 cloves garlic, minced
