– 1/4 cup freshly grated Parmesan cheese (or nutritional yeast + 1/2 TBS lemon juice)
– 2 tablespoons chopped fresh parsley
– 1/2 teaspoon kosher salt

Creamy Mushroom Sauce:
– 2 tablespoons olive oil
– 8 ounces baby bella (cremini) mushrooms, thinly sliced
– 4 cloves garlic, minced or grated

1. Preheat the oven to 375°F. Grease a 9×13 baking dish with olive oil.

2. Blanch the green beans: Bring a large pot of salted water to a boil. Cook the green beans for 4-5 minutes until tender, then transfer them to an ice bath to stop the cooking. Drain and pat dry.

3. Make the crispy onion topping: In a saute pan, heat olive oil over medium-high heat. Cook the thinly sliced onions with a pinch of salt for 7-8 minutes until tender and slightly browned. Remove onions and set aside. In the same pan, toast almond flour or breadcrumbs until golden. Combine with onions, Parmesan cheese, parsley, and salt.

4. Prepare the creamy mushroom sauce: In the same pan, add olive oil and cook mushrooms until tender. Add garlic, thyme, salt, and flour. Stir and cook for a minute. Gradually add milk, whisking until smooth. Season with salt, pepper, and nutmeg. Simmer until thickened. Remove from heat, stir in yogurt.

5. Assemble: Combine green beans with mushroom sauce. Transfer to the prepared baking dish. Top with crispy onion mixture.

6. Bake, uncovered, for 25-30 minutes until golden brown. Sprinkle with fresh parsley and flaky sea salt before serving. Enjoy this wholesome Healthy Green Bean Casserole!
