Step-by-Step Instructions

1. Prepare the Green Beans: Bring a large pot of salted water to a boil. Add the green beans and cook for 4–5 minutes until slightly tender. Drain and immediately transfer them to a bowl of ice water to stop the cooking process. Drain again and set aside.
2. Cook the Vegetables: Melt the butter in a large skillet over medium heat. Add the mushrooms, onion, and garlic, then cook for 5–6 minutes until softened and fragrant.
3. Make the Cream Sauce: Sprinkle the flour over the vegetables and stir continuously for 1 minute. Slowly whisk in the milk and heavy cream until smooth. Add the soy sauce, garlic powder, onion powder, salt, and black pepper. Cook until the sauce thickens.
4. Combine the Ingredients: Fold the cooked green beans into the creamy mushroom sauce until evenly coated.
5. Assemble the Casserole: Transfer the mixture to a greased baking dish and spread it evenly. Sprinkle half of the crispy fried onions over the top.
6. Bake: Bake in a preheated 350°F (175°C) oven for 25 minutes until hot and bubbly.
7. Finish and Serve: Remove the casserole from the oven, sprinkle the remaining crispy fried onions on top, and bake for another 5 minutes until golden brown. Garnish with fresh parsley before serving if desired.

Pro Tips

• Blanch the green beans before baking to keep them bright green and tender-crisp.
• Fresh green beans provide the best flavor and texture, but frozen green beans can also be used.
• Add the final layer of crispy onions during the last few minutes of baking, so they stay crunchy.
• Let the casserole rest for about 5 minutes before serving to allow the sauce to set.
• Use freshly grated Parmesan for even more flavor if adding cheese.
