Why This Version Wins
The All-New Green Bean Casserole keeps the soul of the classic while fixing everything that made it dull. Fresh ingredients, real technique, and thoughtful textures make this a dish people actually look forward to eating—not just tolerating for tradition’s sake.
Directions:
Preheat an oven to 350°F. Lightly butter a deep 2 1/2-quart baking dish. Trim the green beans and halve crosswise. Bring a saucepan of salted water to a boil over high heat. Add the green beans and cook until tender-crisp, about 4 minutes.
Drain and rinse under cold running water.
Pat dry with paper towels and set aside.
In a saucepan, melt the butter over medium heat.
Add the mushrooms and cook, stirring, until they give off their juices and are browned, 6 to 7 minutes. Stir in the 3 Tbs. minced shallots and cook until softened, 2 to 3 minutes.
Sprinkle with the 3 Tbs. flour and stir well. Slowly stir in the half-and-half, stock and soy sauce and then bring to a boil, stirring often.
Reduce the heat to low and simmer, stirring, until thickened, 4 to 5 minutes. Stir in the green beans, season with salt and pepper and transfer the mixture to the prepared baking dish. (The casserole can be prepared to this point up to 1 day ahead, covered and refrigerated.)
Bake until the liquid is bubbling, about 20 minutes (30 minutes if it has been refrigerated).
While the casserole is baking, pour oil to a depth of 2 inches into a heavy saucepan and heat over high heat to 350°F on a deep-frying thermometer.
Line a baking sheet with paper towels and place near the stove.
Cut the remaining 3 shallots crosswise into slices 1/8 inch thick and separate into rings. Place the remaining 1/3 cup flour in a small bowl.
Toss the shallot rings in the flour to coat evenly, shaking off the excess. In batches to avoid crowding, add the shallots to the hot oil and deep-fry until golden brown, about 30 seconds. Transfer to the paper towels to drain.
Remove the casserole from the oven, scatter the fried shallots on top and serve. Enjoy it!

GREEN BEAN CASSEROLE INSTRUCTIONS
First of all rinse the green beans well. Place them in a deep pot, cover with water and bring to a boil. Blanch them for no more than three minutes. Remove, strain and leave for later. You can do this step well ahead of time and then re-heat the green beans in a little water when ready to serve.
As soon as you put the green beans on the stove, add the milk to a saucepan with the whole nutmeg, bayleaf, onions and smashed garlic. Bring the milk to a simmer and be sure to keep stirring so that it doesn’t burn. This shouldn’t take more than two to three minutes. Turn off the flame and let it sit to infuse about 15 minutes. After 15 minutes, remove all the ingredients from the milk.
And then in a well buttered pan, add the mushrooms and cook on high flame for no more than a minute or so. Remove and strain.
Next is to add the butter (45g) in a heavy bottomed sauce pan and let it melt on medium-low flame.
Now add the flour (45g) and using a wooden spoon keep stirring till all is incorporated.
You are going to keep stirring for about 2-3 minutes till the roux starts to froth and most of the flour flavor is cooked off.
Now begin adding the strained warm milk a little at a time. About 1-2 tablespoons to start with and continuously stir.
And then switch to a whisk and keep adding the milk slowly, continuously whisking, adding more as the milk is incorporated.
Once you’ve added all the milk, let the sauce cook for a further ten to fifteen minutes on low heat and keep stirring very often. Now, if you wish you can make the sauce a couple of hours ahead of time then you will need to keep it warm in a bain-marie.
Add the sauce to a pyrex bowl and place over a pot filled with warm water.
The sauce will thicken so just before serving add more warmed milk to it while whisking till desired consistency is reached. Remember to add the milk little by little.
You can also cook the roux the night before, keep it in the fridge covered, then follow the rest of the steps about twenty to thirty minutes before serving. Make sure you start with a warmed roux.
Now add salt and freshly ground pepper.
The mushrooms. Be sure to warm them if you’re making this ahead.
Now, drizzle the vegetable oil into a sautee pan and when the oil is hot, add the onion rings. Cook, stirring very often, till they are golden and crispy.
Lather the hot green beans with the bechamel sauce. Sprinkle with some parmesan if you like.
And, then top with the crispy onions. Alternatively and if you are making certain bits ahead of time, you can add all the chilled ingredients in a casserole, add the bechamel sauce and then bake in a pre-heated oven 350F/160C/3G for about 10-15 minutes.
