Ingredients
- 2 pounds fresh green beans, trimmed and cut into 2-inch pieces
- 8 ounces cremini mushrooms, sliced
- 3 cloves garlic, minced
- 1 medium yellow onion, finely diced
- 2 tablespoons extra virgin olive oil
- 1 cup low-sodium vegetable broth
- 3/4 cup plain Greek yogurt
- 1/4 cup whole wheat flour
- 1 teaspoon Dijon mustard
- 1/2 cup panko breadcrumbs
- 2 tablespoons fresh thyme leaves
- 1 tablespoon grated Parmesan cheese
- 1 teaspoon sea salt, divided
- 1/2 teaspoon freshly cracked black pepper
- 1/4 teaspoon ground nutmeg
- 2 tablespoons unsalted butter, melted
- Fresh parsley for garnish
Instructions
- 1
Preheat your oven to 375 degrees Fahrenheit and position a rack in the middle.
- 2
Bring a large pot of salted water to a boil over high heat, then add the trimmed green beans and cook for 4-5 minutes until bright green and just tender-crisp.
- 3
Drain the green beans in a colander and set them aside to cool slightly.
- 4
Warm 2 tablespoons of olive oil in a large skillet over medium-high heat, then add the diced onion and sauté for 3-4 minutes until translucent and fragrant.
- 5
Stir in the sliced mushrooms and minced garlic, cooking for another 4-5 minutes until the mushrooms release their moisture and begin to brown.
- 6
Whisk together the whole wheat flour and Dijon mustard in a small bowl, then sprinkle this mixture over the mushroom mixture and stir constantly for about 1 minute to cook out the raw flour taste.
- 7
Pour in the vegetable broth slowly while stirring, then add the Greek yogurt and whisk until the sauce is smooth and well combined.
- 8
Season the sauce with 1/2 teaspoon of sea salt, black pepper, and ground nutmeg, then fold in the cooked green beans until everything is evenly coated.
- 9
Transfer the green bean mixture to a 9-by-13-inch baking dish and spread it into an even layer.
- 10
Combine the panko breadcrumbs, fresh thyme leaves, Parmesan cheese, remaining 1/2 teaspoon sea salt, and melted butter in a small bowl, mixing until the breadcrumbs are well coated.
- 11
Sprinkle the herbed breadcrumb topping evenly across the casserole.
- 12
Bake for 20-25 minutes until the topping is golden brown and crispy, and the filling is bubbling gently around the edges.
- 13
Remove from the oven and let cool for 5 minutes before garnishing with fresh parsley and serving warm.
