Green Bean Casserole

Directions

Blanch green beans

Bring a large pot of generously salted water to a boil. Add the green beans and cook for 2–3 minutes, until bright green. Drain well and set aside.

Cook vegetables

Preheat the Roaster Oven to 350°F. Add 4 tbsp. butter to the roasting pan. Add the onions and mushrooms. Cook for 10–15 minutes, stirring occasionally, until the vegetables are softened and lightly browned. Add the garlic and cook for 1 minute.

Make the sauce

Push the vegetables to one side of the roasting pan. Add the remaining 8 tbsp. butter and let it melt. Add the flour and whisk until smooth. Cook for about 3 minutes, stirring frequently. Gradually whisk in the milk. Season with salt and pepper. Cook for 5–8 minutes, stirring occasionally, until the sauce thickens.

Add green beans

Add the green beans to the roasting pan. Gently stir until the green beans are evenly coated with the sauce. Cover and cook at 350°F for 30–40 minutes, until heated through and bubbling.

Add fried onions

Remove the cover and sprinkle the fried onions evenly over the top. Continue cooking uncovered for 5–10 minutes, until the onions are warmed and lightly crisp.
