Preparation

Step 1

Heat oven to 375 degrees. Coat a baking dish with nonstick cooking spray. Bring a large pot of lightly salted water to a boil. Add green beans and cook 4 minutes. Drain, leaving beans in the colander. Return pot to stove. Melt 3 tbsp of the butter in a large nonstick skillet set over medium heat. Add sliced mushrooms and cook 5 minutes, until softened and slightly browned. Season with 1/2 tsp of the garlic salt. Add remaining 3 tbsp butter to pot from green beans. Melt over medium heat and whisk in flour. Cook, whisking, 1 minute. While whisking, add milk. Season with remaining 1/2 tsp garlic salt and the pepper. Bring to a simmer; cook 3 minutes, whisking frequently. Remove from heat and whisk in Swiss cheese. Fold in green beans, mushrooms and 1/3 cup of the fried onions, crushed. Pour into prepared dish. In a small bowl, toss together remaining fried onions and the panko. Sprinkle over casserole and bake at 375 degrees for 25 minutes. To make ahead: Assemble casserole, but do not sprinkle with crumbs until just before baking. Extend bake time by at least 5 minutes to heat through.
