Ingredients
Scale
- 2 lb. fresh green beans
- Kosher salt
- 2 Tbsp. extra-virgin olive oil
- 1 lb. crimini mushrooms
- 6 Tbsp. unsalted butter
- 4 large sprigs thyme
- 2 Tbsp. all-purpose flour
- 1¼ cups whole milk
- 1 cup heavy cream
- 4 garlic cloves, finely grated
- ½ cup grated Parmesan
- Freshly ground black pepper
- ¾ cup French’s fried onions
Instructions
- Preheat the oven to 375°F. Blanch green beans in salted boiling water for about three minutes. Drain and cool before trimming ends.
- Sauté half the mushrooms in olive oil until golden brown, then add butter and thyme, and season with salt. Transfer to a plate and repeat with remaining mushrooms.
- In a saucepan, melt butter, whisk in flour until golden, then gradually add milk and cream, whisking until thickened. Stir in garlic and Parmesan, and season.
- Layer green beans and mushrooms in a baking dish, pour cream sauce over, and cover with foil. Bake until sauce bubbles (25-30 minutes).
- Uncover, bake until golden (15-20 minutes). Add fried onions and bake 3 more minutes. Let sit for 10 minutes before serving.
Notes
Salt the blanching water to enhance green bean flavor.
Let the casserole sit after baking for better texture before serving.
