Green bean casserole

Instructions

1. Preheat oven to 350°F (175°C).
2. Bring a large pot of salted water to a boil. Add the green beans and cook for 5 minutes until bright green and tender-crisp. Drain and set aside.
3. In a large skillet over medium heat, melt the butter. Add the onion and garlic, cooking until the onion is translucent and soft, about 3-4 minutes.
4. Stir in the flour and cook for 1-2 minutes until golden, creating a roux.
5. Gradually whisk in the milk and chicken broth, ensuring there are no lumps. Cook until the mixture thickens, about 3-5 minutes.
6. Add the salt, pepper, nutmeg, and cream of mushroom soup to the skillet. Stir until well combined.
7. Fold in the cooked green beans and half of the crispy fried onions, mixing until everything is coated.
8. Transfer the mixture to a 1 1/2-quart (1.4L) baking dish. Spread evenly.
9. Top with the remaining crispy fried onions.
10. Bake in the preheated oven for 25-30 minutes, until the casserole is bubbly and the onions are golden brown.
