Ingredients
  

Main ingredients
  • 2 pounds fresh green beans, trimmed and cut into 1-inch pieces
  • 1 cup sliced mushrooms (fresh or canned) Fresh gives better texture; canned saves time.
  • 1 cup sour cream Use full-fat for richness.
  • 1 cup shredded sharp cheddar cheese Plus extra for topping if desired.
  • 1 can (10.5 ounces) cream of mushroom soup
  • 1/2 cup fried onions Plus extra for topping; store-bought French-fried onions are fine.
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/4 cup milk Adjust for desired creaminess.
  • 1 tablespoon olive oil Only if using fresh mushrooms.

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.
  2. Bring a large pot of salted water to a boil. Add green beans and blanch for 4–5 minutes until bright and tender-crisp. Drain and plunge into ice water to stop cooking. Drain again and set aside.
  3. If using fresh mushrooms, heat olive oil in a skillet over medium. Add mushrooms and sauté for 5–7 minutes until moisture evaporates and edges brown. Skip if using canned mushrooms.
Mixing
  1. In a large bowl, whisk together cream of mushroom soup, sour cream, milk, Worcestershire sauce, garlic powder, onion powder, and a pinch of salt and pepper until smooth.
  2. Fold in the blanched green beans, mushrooms (sautéed or canned), and 1/2 cup fried onions. Stir until evenly coated.
Baking
  1. Spread the mixture into the prepared baking dish. Sprinkle shredded cheddar evenly over the top.
  2. Bake for 25–30 minutes until bubbling and cheese is melted. Remove, top with additional fried onions, and return to oven for 5–10 minutes until onions are golden and crispy.
  3. Let sit for about 10 minutes to set before serving.

Notes

Feel free to swap Greek yogurt for some of the sour cream to lighten this dish. For a nuttier flavor, use Swiss or Gruyère instead of cheddar. To make it dairy-free, try dairy-free sour cream and cheese alternatives, although the texture may change.
