Perfect Green Bean Casserole is the best green bean casserole from scratch. Fresh green beans and mushrooms and crispy fried onions make this a classic!
Perfect Green Bean Casserole is so incredibly good because it is a homemade green bean casserole with fresh green beans and mushrooms. Perfect? Why would you be so bold to call your green bean casserole perfect? Why is it any better or different than what we’ve served for years? Let me tell you why, but first allow me to make you hungry by telling you about my favorite Thanksgiving recipes.
First and foremost, every Thanksgiving meal deserves an amazing roasted turkey. Next up are the side dishes, and my favorites to serve along side the turkey in addition to my classic green bean casserole are my sweet potato casserole, amazing mashed potatoes, homemade turkey gravy, fresh cranberry sauce, some roasted balsamic bacon brussels sprouts, and some super soft dinner rolls. No Thanksgiving dinner is complete without some side splitting pies and I always serve some variety of apple, pumpkin, and pecan pies.
This green bean casserole was perfect because my green-bean-hating-husband not only ate it, but he devoured all the leftovers in one big bowl. We’ve been scarred by gross green bean casseroles in the past. Hopefully no one will take offense to this, but when we’ve experienced a Thanksgiving dinner where someone brought a green bean casserole made from canned green beans (or what may have resembled a green bean at some point in time), canned cream of mushroom with little black chunks (that may have once been a mushroom), and slices of American (its not real cheese) cheese. YUCK.
When I told my husband I was going to make a classic green bean casserole for Thanksgiving, he gave me a pure look of disgust. Turns out when you use fresh and high quality ingredients, it tastes AMAZING! I did, however, use canned crispy fried onions on top of my homemade green bean casserole. I was all prepared to make my own and then changed my mind for three reasons: 1) I wasn’t sure I could make them without either burning them or making them too greasy, 2) I’m pretty sure most people won’t want to make their own, and 3) Trader Joes makes a delicious crispy fried onion and there are no preservatives or nasty garbage in the can.
So, hopefully I now have you wondering…
How to make green bean casserole:
- I love the added flavor dried mushrooms bring to a homemade green bean casserole, especially when combined with fresh mushrooms. To rehydrate the dried mushrooms, allow them to steep in boiling water for 15 minutes. You will later add the rehydrated mushrooms along with the steeping liquid to the best green bean casserole you’ll ever make.
- The trick to using fresh green beans is to blanch them first by cooking in salted boiling water for 1 minute, then immediately draining and transferring them to a large bowl of ice water. This will make your fresh green beans slightly tender and bright green. Once you make green bean casserole with fresh green beans, you’ll never ever go back to using canned green beans. The difference is like night and day.
- Next you’ll want to sauté the fresh mushrooms in butter, giving them a luscious golden brown color. Fresh green bean casserole deserves fresh mushrooms. If you don’t already own a mushroom slicer, I highly recommend you add one to your kitchen gadgets!
- I love using my dutch oven to cook my fresh green bean casserole because this recipe calls for cooking on the stove top and then in the oven.
- Next you’ll add some flour to the buttery sautéed mushrooms to create a roux and then you’ll add chicken broth while scraping the bottom of the pan to deglaze. At this point you’ll add the rehydrated mushrooms along with the steeping liquid back in as well as some milk which will all thicken together beautifully to make a homemade mushroom gravy for the best green bean casserole.
- One of the many tricks to this fresh green bean casserole is to incorporate some of the fried onions into the casserole as well as adding them to the top.
- This homemade fresh green bean casserole can be prepared the day before and stored in the refrigerator overnight to save you time on Thanksgiving day.
So there you have it… the recipe for classic homemade Green Bean Casserole… made perfect.
This Perfect Green Bean Casserole is made with fresh Hericot Vert green beans, fresh and dried mushrooms, and is topped with crispy fried onions.
- 1 1⁄2 pounds fresh green beans (I used haricot verts)
- .88 ounce dried wild mushrooms
- 1 tablespoon kosher salt
- 4 tablespoons unsalted butter
- 8 ounces fresh mushrooms, sliced
- 1⁄4 cup all-purpose flour
- 1⁄2 cup chicken broth
- 3⁄4 cup milk
- 3⁄4 teaspoon salt
- 1⁄2 teaspoon freshly ground black pepper
- 1 1/2 cups fried onion pieces
- Preheat the oven to 375°F. Lightly grease the baking dish with butter.
- Boil a large pot of water. Once boiling, put 1/2 cup boiling water into a dish and add dried wild mushrooms. Allow to steep for 15 minutes. Add 1 tablespoon kosher salt to remaining boiling water in pot. Blanch green beans by cooking in salted boiling water for 1 minute, then immediately drain and transfer to a large bowl of ice water. This will make your beans slightly tender and bright green.
- In a large skillet or sauté pan, melt the butter over medium-high heat. When it foams, add the fresh mushrooms, spreading them in an even layer. Do not stir or move the mushrooms for 3 to 4 minutes in order to let them brown. Then toss the mushrooms and cook thoroughly on the other side.
- Add the flour to the mushrooms and stir to coat the mushrooms. Allow the flour to cook for several minutes until fragrant. Add the chicken broth and stir well and scrape the bottom of the pan to deglaze. Add the rehydrated mushrooms along with the steeping liquid and whisk the liquid to combine. Stir in the milk and cook, stirring and whisking, until the liquid is slightly thickened.
- Take the mushrooms off the heat and stir in the salt, pepper, green beans, and 1 cup of the fried onions. Spread in the prepared casserole dish (if preparing the day before, do not add the fried onions until you are ready to put it in the oven).
- Cover with aluminum foil and bake for 45 minutes.
- Spread the remaining fried onions on top of the green bean casserole. Bake, uncovered, for 5 minutes, or until the topping is crispy.
