Homemade Green Bean Casserole

• nonstick cooking spray
• 1 pound green beans trimmed
• 8 ounces cremini mushrooms
• 1/2 yellow onion medium
• 2 cloves garlic
• salt as needed, for blanching
• 2 tablespoons salted butter
• 1 teaspoon dried thyme
• 3 tablespoons all purpose flour
• 2/3 cup chicken broth
• 1 1/3 cups half and half
• 1/2 teaspoon salt for vegetables
• 1/4 teaspoon black pepper
• 3/4 cup french fried onions

1. Preheat oven to 400u0b0F.
2. Spray an 8-to-9-inch square casserole dish with nonstick cooking spray. Set aside.
3. Cut green beans into 1 1/2-inch pieces. Slice mushrooms, finely chop onion, and mince garlic and set aside.
4. Boil large pot of salted water. Once water is boiling, add green beans. Blanch green beans until bright green, about 3 minutes. Drain green beans in a colander and rinse with cold water.
5. Set large pot over medium-high heat and add butter. Once butter is melted, add onions and mushrooms to pot. Saute until mushrooms are browned and shrunken and onions are soft, 6-7 minutes. Add garlic and thyme and cook until fragrant, 30 seconds.
6. Sprinkle flour over mushrooms and onions. Stir with spatula to coat. Slowly pour chicken broth into pot, whisking to dissolve flour. Pour in half-and-half and season with salt and black pepper.
7. Cook sauce, whisking constantly, until it begins to bubble and thicken. Reduce heat to medium-low and allow sauce to simmer, whisking occasionally, until it is reduced by about a third, 5-7 minutes.
8. Add green beans to pot and stir to coat with sauce. Pour green bean mixture into casserole dish.
9. Bake casserole on middle rack of oven for 15 minutes.
10. Sprinkle french-fried onions in even layer over top. Continue baking until casserole is bubbling at edges, 5-10 minutes.
11. Check to see that casserole is done. Remove from oven or add time as needed.
12. Allow to rest for 10-15 minutes before serving.
