The BEST Homemade Green Bean Casserole! SO easy, and sure to become your go-to recipe for the holidays!

 

For me, Thanksgiving isn’t complete without an obscenely large batch of green bean casserole. And by obscenely large, I mean there better be enough to feed 10 plus people AND enough leftovers to feed me for at least three days post Thanksgiving. I love the stuff. How could you not? Soft green beans entangled in a creamy, mushroom-laced sauce and topped off with crispy fried onions. It’s the perfect combination of creamy, crunchy and indulgent.

Plus, it’s a heck of a good way to trick your kiddos into eating their veggies. Win!

Typically, I tend to reach for the same classic recipe, but this year, I wanted to try my hand at a slightly richer, homemade version. Because while I’ll all about tradition when it comes to holidays, tradition could always use a little tweaking. In my version, hearty crimini (baby portabella) mushrooms, onions and garlic sautéed in butter are the base and foundation of the casserole, while a splash of dry sherry aids in a sweet, almost nutty undertone.

The cream portion is an equal mixture of whole milk and half and half, which I find to be the perfect combination to achieve that luscious, smooth-as-silk texture we all love about classic green bean casserole. A final splash of worcestershire sauce and a generous hand of salt complete the sauce.

 

Fresh or canned green beans??

Next up, the green beans. Because what’s a green bean casserole without the green beans? I love using these guys because they’re SO quick and require minimal preparation — and let’s be serious, when it’s Thanksgiving and you’re preparing a million dishes, an ingredient that’s ready to go is seriously welcomed. I’ve tried using fresh green beans, and they just don’t have that nostalgic factor I crave in my green bean casserole. I make sure I get to get a variety that has no added sodium, so I can control the amount of salt that goes into the dish.

Annd of course our casserole wouldn’t be complete without that quintessential crunchy topping – fried onions. You could go one of two ways here.

1. You could make your own.

2. You can pick up some store-bought.

I’m a from-scratch-is-better kind of gal when it comes to almost everything, but here, again for nostalgic purposes, I’m just fine using something store-bought. It’s Thanksgiving, you’re allowed to take SOME shortcuts, right? However, I’ve made this several times, and a few of the times I’ve made my own.

I’ve included the instructions if you’re feeling ambitious, but it you’re not, no worries. Really.

 

If you’re going the homemade route, here’s how it goes down.

Thinly sliced onions are soaked in  whole milk and then dunked into a bowl of lightly seasoned flour and plunked in a shallow pool of hot oil. It’s simple and quick, and yields the CRISPIEST fried onions.

All that’s left is to toss some of the onions with the beans and mushroom cream mixture, top with more onions and bake until crispy and bubbly!
