Eating this dish has us asking why on earth we save green bean casserole for ONE time a year?! Sure there are lots of variations of this classic Thanksgiving dish, but we would venture to say that most people want to experience some nostalgia when eating a green bean casserole alongside their turkey. This recipe is the best “from scratch” version we’ve made thus far: the fried red onions are FANTASTIC and deliver the perfect amount of needed tangy saltiness, and what’s underneath is exactly what one tends to want in this traditional dish.
Now, let’s be honest and point out that this might not be the right option for you if you have multiple things going on come Thanksgiving morning, as it takes much more time and effort than does the canned version. If green bean casserole is more of a novelty item on the table at your Thanksgiving dinner and no one cares too much about it, go for the canned variety and skip the bother. BUT if your party does appreciate a great casserole and this is your only assignment (plus maybe a pie or something else that can be made ahead of time), this is a total winner. This is how a green bean casserole was meant to taste, with fresh beans, mushrooms, thyme, garlic and onions (and not so many ingredients you can’t pronounce).
Tip: The temperature of your oil will drop some when you add your onions. We began frying our onions when the deep-fry thermometer registered 360 degrees and fried at 300 degrees for four and a half minutes (the temperature dropped to 300 on it’s own). To make sure you aren’t scrambling at the last minute, you can cover and refrigerate the casserole for up to 4 hours, but keep the topping at room temperature.
Have your kids help you remove the thyme leaves from their sprigs (if the sprigs aren’t soft) and dump ingredients. As you prepare and enjoy this meal with your family, teach them about some of the health benefits of some of the ingredients:
- Fresh green beans provide your body with folic acid, which can help with depression by making sure that feel-good hormones do their jobs.
- White mushrooms are good for your heart because they can help keep plaque from hardening your arteries.
- Eating red onions can help keep your blood sugar balanced.
A few interesting (?) facts:
- The green bean casserole was invented in a Campbell’s Soup Company test kitchen in the 1950’s.
- So, unlike many dishes where a “from scratch” classic is made easier over time using canned & frozen ingredients, here we have a recipe where the original is a canned version and is devised to be made “from scratch.”
- Almost half of the cans of cream of mushroom soup purchased today are used to make green bean casseroles.
Adapted slightly from:Classic Green Bean Casserole
- For the topping:
- 1 large red onion, thinly sliced lengthwise
- 1 cup buttermilk
- Vegetable oil, for frying
- 1 cup all-purpose flour
- 1 cup panko breadcrumbs
- 2 tablespoons finely chopped fresh parsley
- Kosher salt
- For the casserole:
- Kosher salt
- 2 pounds green beans, trimmed and halved
- 3 tablespoons unsalted butter
- 1 pound white button mushrooms, quartered
- 2 cloves garlic, minced
- 2 teaspoons fresh thyme
- 2 tablespoons all-purpose flour
- 1 cup half-and-half
- 1 cup chicken STOCK
- Pinch of cayenne pepper
- ½ cup grated parmesan cheese (about 1 ounce)
- Make the topping: Separate the onion strips and soak in the buttermilk at least 10 minutes. Heat 2 inches of vegetable oil in a large pot or Dutch oven over medium heat until a deep-fry thermometer registers 360 degrees F. Combine the flour, panko, parsley and 1 teaspoon salt in a medium bowl. Working in batches, remove the onion strips from the buttermilk, dip in the flour mixture and fry until golden brown and crisp, about 3 minutes. Transfer to a paper towel-lined plate; season with salt.
- Make the casserole: Bring a large pot of salted water to a boil. Add the green beans; cook until crisp-tender, about 6 minutes. Drain, rinse under cold water and blot dry with paper towels.
- Preheat the oven to 375 degrees F. Melt the butter in a large pot over medium-high heat. Add the mushrooms, season with salt and cook, stirring occasionally, until lightly browned and tender, about 7 minutes. Add the garlic and thyme; cook 1 minute. Add the flour and stir to coat, 1 minute.
- Whisk in the half-and-half, chicken stock, cayenne and ½ teaspoon salt. Bring to a simmer and cook, whisking occasionally, until slightly thickened, about 5 minutes. Stir in the parmesan and green beans. Transfer to a 3-quart baking dish (or 9X13). (You can refrigerate the casserole, covered, for up to 4 hours; keep the topping at room temperature.)
- Bake the casserole until bubbling, about 15 minutes. Stir, then sprinkle with the topping; bake until warmed through, 5 more minutes.
