  • 2 tablespoons French fried, dried onions
  • 1 tablespoon soy sauce
  • 3 ounces shredded mild cheddar
  • Kosher salt and freshly ground black pepper


  1. Preheat Your Oven: Preheat your oven to 350°F (175°C) and grease a small baking dish.
  2. Steam the Green Beans: Steam the green beans until they are tender but still slightly crisp. You can steam them on the stovetop or in the microwave.
  3. Prepare the Creamy Sauce: In a mixing bowl, combine the softened cream cheese, heavy cream, soy sauce, shredded cheddar cheese, and a pinch of salt and pepper. Mix until well combined and smooth.
  4. Combine the Ingredients: In the greased baking dish, layer the steamed green beans on the bottom. Pour the creamy sauce mixture over the green beans, ensuring they are evenly coated.
  5. Add the Crunchy Topping: Sprinkle the French fried onions over the top of the casserole, distributing them evenly.
  6. Bake Until Golden and Bubbly: Transfer the baking dish to the preheated oven and bake for 20-25 minutes, or until the casserole is heated through and the topping is golden brown and crispy.
  7. Serve and Enjoy: Once baked, remove the casserole from the oven and let it cool slightly before serving. Garnish with additional French fried onions if desired and serve warm.

Cook Notes:

  • Fresh or Frozen Green Beans: You can use either fresh or frozen green beans for this recipe. If using frozen, be sure to thaw them before steaming.
  • Cream Cheese Consistency: To ensure the cream cheese blends smoothly into the sauce, make sure it is softened at room temperature before mixing.
  • Adjusting Seasonings: Feel free to adjust the seasonings according to your taste preferences. You can add additional salt, pepper, or even garlic powder for extra flavor.


  • Bacon and Mushroom Addition: Add cooked and crumbled bacon or sautéed mushrooms to the creamy sauce mixture for added flavor and texture.
  • Almond Flour Topping: For a low-carb alternative to French fried onions, try topping the casserole with a mixture of almond flour, grated Parmesan cheese, and melted butter.

Keto Versions:

  • Almond Milk Substitution: Substitute almond milk for the heavy cream to reduce the carb count even further while maintaining creaminess.
  • Cauliflower Addition: Add steamed cauliflower florets to the green beans for extra bulk and a boost of nutrients.
