  • 1 clove Garlic (optional) - Minced
  • 1 teaspoon Soy sauce - Enhances umami flavor
  • ½ teaspoon Worcestershire sauce - Adds depth to the sauce
  • 1 teaspoon Fresh thyme (Optional) - for added richness

Instructions 

Prepare the Green Beans

  • Bring a large pot of salted water to a boil.
  • Add trimmed green beans and blanch for 3 minutes until bright green.
  • Transfer beans immediately to an ice bath to stop cooking. Drain and pat dry.

Make the Creamy Base

  • In a mixing bowl, combine Campbell’s Cream of Mushroom Soup, milk, black pepper, soy sauce, Worcestershire sauce, and fresh thyme.
  • Stir until fully blended and smooth.

Assemble the Casserole

  • In a 9x13 baking dish, add green beans and pour the sauce mixture over them.
  • Mix gently to coat evenly.
  • Stir in half of the crispy onions for added crunch inside the casserole.

Bake the Casserole

  • Preheat oven to 350°F (175°C).
  • Cover the baking dish with foil and bake for 25 minutes.

Add the Final Topping & Finish Baking

  • Remove foil and sprinkle the remaining crispy onions on top.
  • Bake uncovered for another 5 minutes or until the topping is golden brown.

Rest & Serve

  • Let the casserole rest for 10 minutes before serving. This allows the flavors to settle and makes it easier to serve.
