1 ½poundsfresh or frozen green beansdefrosted, trimmed and cut (about 5 cups)
1cupfreshly shredded cheddar cheese
1 ½cupscrispy fried onionsstore bought, or use the option in the notes, divided
Instructions
Preheat the oven to 350°F. Spray a 9" x 13” casserole dish with cooking spray, and set aside.
Prepare the mushroom cream sauce: in a blender, combine all the ingredients for the mushroom cream sauce. Blend until smooth. Pour into a medium size sauce pan and heat over medium heat until the sauce thickens enough to coat the back of a spoon, about 5 minutes. Set aside.
If using fresh green beans: Bring a saucepan full of water to a boil. Add in the green beans and cook until just crisp-tender, 6-8 minutes. Drain and set aside. If using frozen, defrost fully, drain water, and set aside.
In a large bowl, combine the mushroom cream sauce, green beans, cheddar cheese, and 1 cup of the crispy fried onions. Pour into the prepared baking dish.
Bake uncovered in the preheated oven for 30-35 minutes or until the casserole is bubbly. Top casserole with remaining crispy onions and then return to the oven for 10 minutes or until onions are brown and crispy.
Notes
You can use store bought crispy fried onions for a classic version, or for a from-scratch variation, you can make your own parmesan fried onions. Heat 1 tablespoon of oil in a large skillet over medium-high heat. Add in 1 large yellow onion thinly sliced and sauté until tender and beginning to brown, about 5 minutes. Remove from heat and transfer the onions to a small bowl. Mix in ¼ cup fresh grated Parmesan cheese, ½ cup Panko breadcrumbs, and ¼ salt. Spread on a lined baking sheet and bake in a 425°F oven for 5-7 minutes or until golden brown. Use as listed in the recipe.
This can be made two days ahead of time. Prepare as listed up until the baking step, just keep the reserved crispy onions aside in a separate container. Cover the casserole and pop it in the fridge. Make sure to bring it out on the counter to warm up for 60 minutes before baking.
We love baby Bella mushrooms for a stronger mushroom flavor, but button mushrooms are also delicious.
