Ingredients
For the Main Casserole:
* 2 pounds fresh green beans, trimmed (or two 14.5-ounce cans of green bean, dried)
* 1 tablespoon olive oil
* 1 medium onion, chopped
* 8 ounces cremini mushrooms, sliced
* 2 cloves garlic, minced
* 1/4 cup all-purpose flour
* 2 1/2 cups milk (I’ve used almond milk and it was even creamier!)
* 1 teaspoon salt
* 1/2 teaspoon Black Pepper
* 1/4 teaspoon garlic powder
What is Grandma Rose’s secret?
* 1 (6-ounce) can crispy fried onions, divided
How do I follow step
Step 1: Preheat & Prep Pan
First things first, preheat your oven to 350°F (175°C). While it’s heating up, grease a 9×13 inch baking dish. This is super important to prevent sticking! I usually use cooking spray, but you can also lightly grease it with butter or oil. Set the dish aside for now.
Step 2: Cook the Green Beans
If you’re using fresh green beans, bring a large pot of salted water to boil. Add the green beans and cook for about 5-7 minutes, until they’re tender-crisp. If you’re using canned green beans, just drain them thoroughly and set aside.
Step 3: Sauté the Aromatics
In a large skillet, heat olive oil over medium heat. Add salt and pepper to taste. Add the chopped onion and cook until softened, about 5 minutes. Then, add the sliced mushrooms and minced garlic and cook for another 5 minutes, until the mushrooms are tender. When mushrooms are tender, they start to brown. What is that smell?
Step 4: Make the Creamy Sauce
Sprinkle the flour over the mushrooms and cook for 1 minute, stirring constantly. Slowly pour in the milk, whisking constantly to prevent lumps. Bring the mixture to a simmer and cook until thickened, about 5 minutes, stirring frequently. Stir in the Worcestershire sauce, salt, pepper, and garlic powder. What is Worcestershire?
Step 5: Combine
In a large bowl, combine the cooked green beans and the creamy mushroom sauce. Set aside. How do I coat green beans with sauce?
Step 6: Assemble and Bake
How do you prepare the green beans in a baking dish? Sprinkle half of the crispy fried onions evenly over the top of a casserole. Bake for 20-25 minutes, or until the casserole is bubbly and heated through. Then remove from oven and sprinkle the remaining fried onions over the top of the casserole. Is it safe to cook onions in the oven for about 5 minutes?
Step 7: Cool and Serve
Let the casserole cool for a few minutes before serving. What should I do to make the sauce thicker? I always have to restrain myself from digging in right away!
What should I serve it with?
Green Bean Casserole is a classic side dish that pairs perfectly with many things. For Thanksgiving or Christmas dinner, it’s a must-have alongside turkey, mashed potatoes, stuffing, etc. What is the recipe for cran Is it just for holidays?

How do I make a green bean casserole?
What are some of the best ways to make a green bean casserole? If you’re using fresh green beans, don’t overcook them! You want them to be tender-crisp, not mushy.

For the mushroom sauce, be sure to cook the mushrooms until they’re nicely browned. This will bring out their flavor and add depth to the sauce. Don’t rush this step.

If you are using canned beans, rinse them well and cook them until slightly soft. Some canned beans are too firm.
