Instructions
This is an overview of the recipe. The full instructions are below in the recipe card.
Step 1: Preheat the oven to 350°F/177°C. Prepare a 9" x 13" casserole dish with nonstick cooking spray.
Step 2: In a medium skillet over medium-high heat, melt the butter. To the butter add the mushrooms and onion. Cook for 5 to 6 minutes or until the vegetables are softened.
Step 3: Add the garlic and stir for another 30 seconds to blend the flavors. Add the flour, salt, and pepper to the skillet and stir to coat the onions and mushrooms.

Frequently Asked Questions
This dish is delicious and can be served on its own, but you can also serve it with rolls or a bread side, and a fresh salad.
To avoid a runny green bean casserole, make sure that your sauce is thickened before adding it to the rest of the ingredients. You can thicken it by cooking it longer on the stove, or by adding a cornstarch slurry.
Yes, you can use water. But, your sauce will be less creamy and thinner. I recommend using half and half or at least milk.
Variations
