Bon Appetit’s Best Green Bean Casserole
Recipe Overview
This is not a quick side dish. It’s a process. It’s from scratch. And it tastes like it. So, if you want some really good green bean casserole, make BA’s Best Green Bean Casserole.
Ingredients List
Ingredients:
- 2 pounds green beans
- Salt & Pepper
- ¾ cup fried onions
Mushrooms
- 1 pound cremini mushrooms, sliced & divided
- 4 tbsp unsalted butter, divided
- 4 large sprigs thyme
Béchamel
- 2 tbsp all-purpose flour
- 2 tbsp unsalted butter
- 1 ¼ cups whole milk
- 1 cup heavy cream
- 4 garlic cloves, finely grated
- ½ cup parmesan
Step 1: Cook the Green Beans
Preheat oven to 375°. Working in batches, cook green beans in a large pot of boiling salted water until bright green and half way to tenderness, about 3 minutes per batch. Drain and let cool; trim stem ends.
NOTE: I made this a second time and trimmed the ends before we cooked the green beans. I found it substantially easier to trim the uncooked beans and it didn’t make any difference in the dish.
Step 2: Cook the Mushrooms
Heat 1 Tbsp oil in a large skillet over medium-high heat. Cook half of mushrooms, without stirring, until golden brown underneath, about 2 minutes. Toss and continue to cook, tossing occasionally, until browned on both sides, about 3 minutes more. Add 2 Tbsp butter and 2 thyme sprigs to pan. Cook, tossing occasionally, until butter browns and mushrooms are dark brown and very tender, about 4 minutes longer. Season with salt and transfer to a plate. Repeat with 2 tbsp butter, salt, and remaining oil, mushrooms, and thyme.
Step 3: Make the Béchamel
Melt remaining 2 Tbsp of butter in a large saucepan over medium-low heat. Whisk in flour and cook, whisking occasionally, until roux golden brown and smells mildly nutty, about 4 minutes. Whisk in milk and cream. Increase heat and bring to a simmer, whisking often, and cook until bechamel sauce is thick and bubbling, about 5 minutes. Remove from heat and whisk in garlic and Parmesan; season with salt and pepper
Step 4: Assemble and Cook
Arrange green beans and mushrooms in a 2 quart baking dish. Pour sauce over (it may not look like enough, but it will get softer as it bakes). Cover tightly with foil and bake until sauce is bubbling, 25 to 30 minutes. Uncover and continue to bake until casserole is lightly browned on top and around the edges, 15 to 20 minutes longer. Top with fried onions and continue to bake just until onions are slightly darker and fragrant, about 3 minutes. Let sit 10 minutes to set before serving.
NOTE: I just layered the green beans, then mushrooms, then poured the sauce on top because I didn’t know what “arrange” meant. It worked fine!
Conclusion
This recipe ended with me shoveling green bean casserole out of the baking dish and into my mouth. My whole family quickly joined me. I guess that’s all you really need to know about this one. Lol. So long as you have the time and are willing to do a fair amount of dishes, this one is a keeper!
