If you think you don’t like green bean casserole, withhold judgment until you’ve tried this entirely from-scratch version. It has all the classic elements of the Thanksgiving favorite, but its base is a mushroom gravy amped up with red-wine vinegar, red-pepper flakes and fresh thyme rather than a can of soup. If you don’t want to fry the onions yourself (we understand), you can always substitute 1½ cups store-bought fried onions or even crispier fried shallots.

Preparation

Step 1
Make the onions: In a medium bowl, combine the onions with the flour, bread crumbs and salt, and toss to coat the onion pieces.
Step 2
In a heavy skillet with high sides, pour enough oil to reach ½-inch up the side. Heat over medium-high until the oil is hot — a drop of water should sizzle and sputter when flicked into the oil.
Step 3
Add the onions in batches, taking care not to overcrowd them. Fry until golden-brown (they don’t have to be deep brown, as they’ll continue cooking in the oven), about 5 to 6 minutes, then use a slotted spoon or a pair of tongs to transfer to paper towels. Sprinkle lightly with salt. Repeat until you’ve fried all of the onions.
Step 4
Butter a shallow 4-quart baking dish and heat the oven to 400 degrees.
Step 5
Blanch the green beans: Bring a large pot of water to a boil with an ice bath nearby. When boiling, salt the water generously, add the green beans, and cook for 4 to 5 minutes, until slightly tender and bright green. Immediately transfer beans to the ice bath. When beans are chilled, drain and set aside.
Step 6
Pour water out of the pot, wipe dry and return to the stovetop. Over medium-high heat, melt 3 tablespoons butter. When melted, add the red-pepper flakes and thyme, and stir until fragrant, about 1 minute. Add the sliced mushrooms and cook, stirring occasionally, until they start to brown significantly, 8 to 10 minutes. Add 1 teaspoon salt and sliced garlic and stir until fragrant, another 1 to 2 minutes.
Step 7
Sprinkle the flour all over and stir to coat the mushrooms. Gradually add the stock and milk, and bring to a simmer, stirring all the while. Turn the heat down to medium and continue to stir until the sauce is thick and creamy and coats the back of a spoon, 6 to 8 minutes. Remove from heat. Add nutmeg, black pepper, vinegar and Worcestershire, if using. Taste for salt, pepper and acidity.
Step 8
Add the green beans and half of the onions, stir to combine, and transfer to prepared baking dish. Top with remaining onions and bake for 15 to 20 minutes, until bubbling. Serve immediately.

Tip

You can make the onions a day in advance. Cover loosely with plastic wrap and store at room temperature. The beans can be blanched and mixed with the mushroom sauce a day in advance.

This is starting to sound like FN. How is smoked paprika and black pepper a comparable substitute for fresh thyme? What about dried thyme? I certainly understand not wanting to trek to the store for one item, but the point of comments on NYT cooking is to assess the recipe as is, so others can determine its quality/ranking and, in turn, decide whether or not to try the recipe. Sorry to sound so critical.

Wow!!! Yummy. Great way to use the abundance of green beans from the garden. The mushroom sauce is exquisite, I used soy sauce since we didn’t have Worcestershire Sauce. Fried onions were so eatable. Hard to not eat them all before assembling the dish!

This is excellent. Frying your own onions takes this dish to the next level.

This is seriously so so so good! This is NOT your mother’s green bean casserole with a can of soup and French fried onions from a can. I think these onions were the first things I have ever deep friend, and oh my goodness but are they delicious! I always double the amount called for because I have to snack on them while preparing the dish, and the casserole is only better with the more onions you add. It has a bit of a kick - add extra red pepper flakes if you want more, but I find the amount called for gives it just the right amount of heat.

I made this last year for Thanksgiving, and found that it tasted amazing but wasn't quite saucy enough. Increased the soup quantity by adding an extra tbsp of flour and an extra quarter-cup each of stock and milk. I like to grate some gruyere cheese into the casserole as well.

Really delicious and worth the effort to make from scratch! But took me more than 1 hour (and I make NYT recipes regularly, usually within the time prescribed)
