About this dish
Snappy green beans, a soft mushroom cream sauce, and a crunchy fried onion topping give this American casserole three textures in one dish.

The beans get just three minutes in boiling water and a cold rinse, leaving the oven to finish them. The fried onions wait until near the end of baking, since at the start they would lose their crunch.
Ingredients
Instructions
- 1
Trim the 400 g green beans, then blanch them in boiling water for exactly 3 minutes.
Transfer them straight to cold water, drain well, and keep them crisp so they do not turn soft during baking.
- 2
Melt 2 tablespoons butter in a pan over medium heat, then saute the half onion first.
When it turns translucent, add 150 g mushrooms and cook until their moisture reduces and the mushroom flavor concentrates.
- 3
Sprinkle in 2 tablespoons flour and cook over medium-low heat for about 1 minute to remove the raw flour taste.
Stir constantly so the roux coats the vegetables without sticking or browning too fast.
- 4
Pour in 250 ml milk gradually while stirring, letting each addition loosen the roux before adding more.
Season with 1/2 teaspoon salt, then turn off the heat when the sauce flows thickly and smoothly.
- 5
Add the drained green beans to the cream sauce and fold until every piece is lightly coated.
Transfer to a baking dish in an even layer, spreading the sauce to the edges for steady heating.
- 6
Bake at 180C for 20 minutes, until the edges begin to bubble.
Remove the dish, scatter 1 cup fried onions over the top, and bake 5 minutes more so the topping crisps without burning.
