For the topping:

  • 1 tbsp butter
  • 1 large onion
  • 1 cup mozzarella
  • 1/2 cup Parmesan

For the sauce:

  • 1 1/2 cups heavy cream
  • 4 oz cream cheese
  • 2 cups mushrooms — sliced
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1 clove garlic
  • 1 tbsp butter
  • 1 clove garlic
  • 1-2 tsp cornstarch — optional


  • 1 lb green beans
  • bacon — for topping, optional


  1. Sauté onions in 1 tablespoon of butter until golden. Transfer to a plate.

  2. Prepare the green beans, by cooking in hot boiling water for 4-5 minutes, then drain and rinse with ice cold water.

  3. To prepare the sauce: cook mushrooms in butter, seasoned with salt and pepper for 4-5 minutes, stirring frequently. Add garlic (optional) and cook for 1 minute. Add heavy cream, cream cheese, salt and pepper. Cook stirring frequently for 5 minutes, until the sauce gets creamy and there are no bug chunks of cream cheese. If you'd like to thicken the sauce, you can mix cornstarch with 2 tbsp of cold water and add it to the sauce. Stir to combine.

  4. Grease a 9x9 baking dish (you can use a similar sized dish) with cooking spray. Add the green beans. Top with the sauce. Add cheeses and onion.

  5. Bake for 30 minutes, until the top is bubbly.
