- 1 tsp soy sauce
- ½ tsp salt
- ¼ tsp black pepper
- 1 ½ cups fried onions (e.g., French’s)
- Optional: ½ cup shredded cheddar cheese for extra richness
Step-by-Step Process
- Blanch Green Beans: Bring a large pot of salted water to a boil. Add green beans and cook for 5 minutes until crisp-tender. Drain and plunge into an ice bath to stop cooking. Drain again and set aside.
- Sauté Aromatics: In a large skillet, melt butter over medium heat. Add onion and mushrooms; sauté for 6-8 minutes until softened. Add garlic and cook for 1 minute until fragrant.
- Make Sauce: Sprinkle flour over the mushroom mixture and stir for 1-2 minutes to form a roux. Gradually whisk in milk and cream, stirring constantly to avoid lumps. Cook for 3-4 minutes until thickened.
- Season: Stir in soy sauce, salt, pepper, and optional cheddar cheese until smooth. Remove from heat.
- Combine: Add blanched green beans to the sauce, stirring to coat evenly. Transfer to a greased 9×13-inch baking dish.
- Bake: Preheat oven to 375°F (190°C). Top the casserole with fried onions. Bake for 20-25 minutes until bubbly and golden.
- Serve: Let rest for 5 minutes before serving hot.
