The Best Green Bean Casserole
Crisp, fresh green beans are the star of the show in this Classic Green Bean Casserole recipe. This recipe is made, mostly, from scratch with fresh ingredients and topped with crispy onion rings. Dare I say, better than grandma’s?
Green Bean Casserole
Thanksgiving is just around the corner and there are some must have dishes I can’t do without like fluffy mashed potatoes, or my favorite sausage stuffing and, of course, cranberry sauce. They’re just staples at our holiday table and isn’t the holiday all about the sides, really?
My favorite side dish of all time is Classic Green Bean Casserole but many times I’ve been disappointed with the various versions I’ve tried….almost always made with canned green beans. The green beans always ended up super soft, way over cooked and somewhat soggy.
I knew there was a better way to make it the Very Best Green Bean Casserole it could possibly be. Tender, crisp green beans, white button mushrooms and the must have French Fried Onions for the perfect crunch right on top. While I used to make a homemade mushroom soup base to use as the sauce, I find that the canned Cream of Mushroom soup makes a creamy sauce like no other and without having to stand over the stove longer than necessary.
I DO use cream of mushroom soup to make my favorite cheesy Brussel Sprouts because it’s just perfect and makes it ultra creamy.
What is Green Bean Casserole?
This recipe is very similar to the Campbell’s Green Bean Casserole recipe except I don’t use soy sauce or a few other additions that they include. Baked until bubbling then topped with crispy onions, this recipe will be a staple at your holiday table to. You can make this easy casserole without breaking the bank, too.
This easy Green Bean Casserole recipe is now a staple for every holiday….not just Thanksgiving. You can find this on our table for Easter, Christmas, New Year’s Eve and more.
Ingredients For Green Bean Casserole
The ingredient list is short and easy to find at any well stocked grocery store:
- Green Beans – Fresh is best and that’s what I use for this recipe. You can totally substitute with canned or frozen green beans if you can’t locate fresh but the casserole consistency will be a little softer and the greens will have less crispness to them.
- Cream of Mushroom Soup – You can use my homemade cream of mushroom soup if you’re adverse to the can but trust me when I say that the sauce is extra creamy when you use a condensed soup. If you don’t like mushroom soup….you can use Cream of Chicken soup!
- Mushrooms – This recipe calls for sauteed mushrooms but you can skip them if you’re not a fan….or you have a mushroom hating relative. But don’t skip the saute because it gives the mushrooms a great caramelization that you won’t get without that step.
- French Fried Onions – I use canned fried onions because that’s what we used growing up when my mom would make the French’s Green Bean Casserole recipe. They’re perfectly crispy and flavorful and I could totally eat them like potato chips so why change a good thing.
How To Make Green Bean Casserole
- Preheat the oven to 375 degrees.
- Bring a large pot of salted water to a boil and add the green beans.
- Cook the green beans for 3 minutes and then immediately transfer to a big bowl of ice water to stop the cooking. Drain and set aside.
- Heat the olive oil in a large skillet over medium heat. Add the onions and cook until slightly softened.
- Add the mushrooms to the pan and cook for 2-3 minutes. Flip the mushrooms and cook for 1-2 more minutes. Remove from the heat and set aside.
- In a medium bowl, whisk together the mushroom soup, sour cream, milk, nutmeg, cayenne and salt.
- Combine the green beans, mushroom mixture and cream soup mix in a bowl, stirring to combine.
- Transfer to a 13×9 inch baking dish and transfer to the oven.
- Bake for 20 minutes and then top the casserole with the french fried ovens evenly.
- Return to the oven and bake for an additional 10 minutes or until the onions are golden brown.
- Serve immediately.
How To Make Green Bean Casserole in Advance
To make green bean casserole ahead of time, you can assemble the whole casserole with the exception of the crispy onions and store in the refrigerator covered tightly with plastic wrap.
Remove the casserole from the refrigerator approximately 30 minutes before baking, remove the plastic wrap and bake according to the recipe instructions.
Sometimes we like to mix things up and make the Best Green Bean Casserole even better.
- Bacon – Crispy bacon is fantastic mixed into your green bean casserole before baking or sprinkling on top with the crispy onions!
- Gluten Free – This green bean casserole is totally gluten free….just be sure to check the container of french fried onions to be sure your’s are truly gluten free. It does vary by brand.
- Cheese – Make your green bean casserole with cheese by mixing in shredded cheddar cheese before baking. You could also add gruyere, mozzarella, goat cheese or jalapeno cheese for a little kick to mix things up, too.
Crock Pot Green Bean Casserole
Sometimes we run out of space in the oven and need to pull out all the small kitchen appliances. Thankfully, this Green Bean Casserole can be made in the slow cooker, too!
Simply follow the instructions up to the transfer to a baking dish and, instead, add to the Crock Pot. Cook your casserole on high for 3-4 hours and top with the french fried onions 30 minutes before the cooking time is done. SO EASY!
