This French Green Bean Casserole is full of tender green beans, flavorful and creamy sauce, and finished off with crunchy fried onions. It's a fresh take on a classic side dish.
Preheat the oven to 350°F. Grease a 9X13 baking pan with butter or cooking spray and set it aside.
Fill a large pot with enough water to cover the green beans and bring it to a boil.
Add the green beans and cook for 2-3 minutes. Drain them in a colander.
Using the same pot, heat some avocado oil over medium heat.
Add the chopped onions and mushrooms, and cook for 3-5 minutes until soft and the onions look transparent.
Add the minced garlic and cook for 1-2 more minutes.
Stir in the cream of mushroom soup, buttermilk, and chicken broth.
Mix everything and cook for 5-8 minutes, stirring occasionally, until it's warmed through.
Take the pot off the heat and mix in the green beans, shredded cheese, and ¾ cup of the crispy fried onions.
Stir it all together until well combined.
Pour the mixture into your prepared baking pan.
Bake uncovered for 30-35 minutes, until the sauce is bubbly.
Take the pan out of the oven and sprinkle the remaining crispy fried onions (2 ¼ cups) on top.
Please put it back in the oven for 10 minutes to crisp up the topping.
Sprinkle some fresh parsley on top, and serve as a side dish.
Enjoy!
Notes
I used fresh green beans in this recipe. However, you can use canned or frozen in a pinch. Fresh does give the best texture.
Store-bought fried onions had a nice crispy texture to the casserole; you can use homemade fried onions as well.
Blanching the fresh green beans before adding them to the casserole helps retain their vibrant color and ensures they are tender but still have a bit of a crunch. So, don't skip this step.
Bake the casserole uncovered to allow the top to get golden brown and crisp.
