Ingredients
Scale
- 2 lbs fresh green beans, trimmed and snapped
- 1.5 cups plain non-fat Greek yogurt (at room temperature)
- 8 oz cremini mushrooms, sliced
- 2 cloves garlic, minced
- 1/2 cup yellow onion, diced
- 1 cup low-sodium chicken or vegetable broth
- 2 tablespoons cornstarch (or arrowroot powder)
- 1/2 cup grated Parmesan cheese
- 1 cup crispy fried onions
- 1 tablespoon olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
Instructions
- Step 1: Blanch the Green Beans Bring a large pot of salted water to a boil. Add the trimmed green beans and cook for about 5 minutes until they are bright green and crisp-tender. Immediately drain the beans and plunge them into a large bowl of ice water. This stops the cooking process and keeps them from becoming mushy in the oven. Once cooled, drain them again and pat dry.
- Step 2: Sauté the Aromatics and Mushrooms Preheat your oven to 350°F (175°C). In a large skillet, heat the olive oil over medium heat. Add the diced onions and sliced mushrooms. Sauté for 6 to 8 minutes until the mushrooms have released their moisture and turned golden brown. Add the minced garlic and cook for another 60 seconds until fragrant.
- Step 3: Prepare the High-Protein Cream Sauce In a small bowl, whisk the cornstarch into the cold broth until fully dissolved. Pour the broth mixture into the skillet with the mushrooms. Simmer for 2 to 3 minutes until the liquid thickens into a glossy sauce. Remove the skillet from the heat. Carefully whisk in the Greek yogurt, salt, pepper, garlic powder, and Parmesan cheese. Ensure the heat is off to prevent the yogurt from curdling.
- Step 4: Combine and Bake Place the blanched green beans into a 9×13 inch baking dish. Pour the creamy mushroom sauce over the beans and toss gently until everything is evenly coated. Spread the mixture into an even layer. Top the casserole with the crispy fried onions. Bake for 20 to 25 minutes until the sauce is bubbling and the onions are deeply golden and crunchy.
