AN EASY GREEN BEAN CASSEROLE RECIPE
Creamy sauce tossed with green beans and mushrooms and topped with homemade french-fried onions – the classic green bean casserole gets an amazing update! Please, dig in!
This easy side dish is a staple for Thanksgiving dinner, but it’s also just as perfect to be enjoyed year round.
Green Bean Casserole is definitely one of my favorite dishes to also bring to get-togethers or family dinners. This includes my Lightened-Up Creamy Green Bean Casserole. It is easy to make at home and bring with you wherever you go because, it can be made ahead of time and baked just before serving.
Major plus? This recipe can be made weeks ahead of time and frozen. Sans the onions.
This particular recipe made me realize how much more delicious this classic can taste when made with fresh green beans, fresh mushrooms, and a delicious homemade sauce. I also like making my own French “Fried” Onions, but I admit, the store-bought ones are damn good. Like, SO darrrn good.
To add, this recipe also uses frozen green beans. Hey. If there’s a step to skip without sacrificing flavors and texture, I’m there! Canned green beans are on my heck-to-the-no list, fresh green beans take too long to trim, thus frozen green beans are my veg of choice. Moreover, they are already cooked. Your job is to just set them on the counter to thaw.
HOW TO MAKE GREEN BEAN CASSEROLE
- Thaw green beans and drain.
- We will then begin with sautéing the onions and mushrooms for 10 minutes.
- A mixture of broth and half & half will be added and cooked until thickened.
- At this point, we will stir in the green beans and cook for about 8 minutes, or until the green beans are tender.
- If serving right away, you will want to prepare the French Fried Onions. You can also use the store-bought kind. If you are preparing the green bean casserole for later use, do not add the onion topping until ready to bake.
- Once the green beans are cooked, you can transfer it all to a 4-quart baking dish and bake for 20 minutes at 375F, or until bubbly.
- Add the prepared onions on top and continue to bake for 5 more minutes, or until onions are browned on top.
HOW TO GREEN BEAN CASSEROLE AHEAD OF TIME
- Assemble the casserole without the onion topping; let completely cool. Wrap with plastic wrap and aluminum foil and refrigerate for up to 3 days.
- When ready to serve, remove from the refrigerator while the oven preheats. Bake as directed.
HOW TO FREEZE GREEN BEAN CASSEROLE
- Assemble the casserole without the onion topping; let completely cool. Wrap with plastic wrap and aluminum foil and freeze for 2 weeks to 1 month.
- Take out of the freezer the night before and thaw out in the fridge.
- The next day, bring the casserole to room temperature and continue as directed.
If you’re looking for a great green bean casserole recipe, look no further. This version results in a creamy casserole with plenty of texture and crunchy topping. Make this easy green bean casserole even easier by pulling it together weeks ahead of time, then pop it into the oven before the big meal.
