Instructions
Blanch the Green Beans
Bring a large pot of salted water to a boil. Add the trimmed green beans and cook for exactly 5 minutes until bright green and tender-crisp. Immediately transfer them to a bowl of ice water to stop the cooking process, then drain and pat dry.
Make the Mushroom Cream Sauce
Melt butter in a large oven-safe skillet over medium-high heat. Add the sliced mushrooms and cook for 6 to 8 minutes until deeply browned. Add the garlic and cook for 1 more minute, then pour in the heavy cream and simmer until the sauce thickens slightly, about 5 minutes.
Assemble the Casserole
Preheat your oven to 375 degrees Fahrenheit. Add the blanched green beans to the skillet with the mushroom cream sauce and stir to combine. Transfer to a greased 9x13 baking dish if not using an oven-safe skillet. Top with three quarters of the crispy fried onions.
Bake and Finish
Bake uncovered for 20 to 25 minutes until the sauce is bubbling around the edges. Remove from the oven and immediately scatter the remaining crispy fried onions over the top. Let it rest for 5 minutes before serving so the sauce can settle slightly.
