Cooking Steps

  1. Preheat the oven to 190 °C (375 °F). Position the oven rack in the center for even baking.
  2. Prepare ingredients: wash and trim 1.5 pounds (about 680 grams) of fresh green beans, removing any tough ends. Cut them into 5 cm (2-inch) pieces.
  3. In a large pot, bring 2 liters (8 cups) of water to a boil over high heat, then add the prepared green beans. Blanch for 5–7 minutes until they’re vibrant green and slightly tender yet still crunchy.
  4. Quickly drain the green beans in a colander and immediately plunge them into a bowl of ice water for 3 minutes to stop the cooking process. Drain again and set aside.
  5. In a large mixing bowl, combine 2 cans (10.5 ounces each) of cream of mushroom soup, ½ cup (120 ml) of milk, 1 teaspoon of soy sauce, ½ teaspoon of salt, ¼ teaspoon of black pepper, and optional ½ teaspoon of garlic powder. Stir until smooth.
  6. Fold in the blanched green beans into the soup mixture until evenly coated.
  7. Lightly grease a 3-liter (3-quart) baking dish with non-stick spray or butter. Transfer the green bean mixture into the baking dish, spreading it evenly.
  8. Top the casserole with 1.5 cups of fried onions, spreading them out evenly for an even crunch. If using optional shredded cheddar cheese, sprinkle 1 cup evenly over the onions.
  9. Bake in the preheated oven for 25–30 minutes or until the top is golden brown and the casserole is bubbling around the edges. The aroma should be rich and savory at this point.
  10. Remove the casserole from the oven, and let it rest for 5–10 minutes before serving. This allows the mixture to set slightly.
  11. Serve warm, garnishing with additional fried onions if desired.

Variations

Cheesy Broccoli Green Bean Casserole:

Add 1 cup (150 grams) of steamed broccoli florets and use 1 cup (120 grams) of shredded cheddar cheese instead of or in addition to fried onions for a creamy and cheesy variation.

Vegan Green Bean Casserole:

Replace the cream of mushroom soup with a homemade or store-bought vegan cream soup and use almond milk (120 ml) instead of regular milk; top with vegan fried onions for a plant-based option.

Gluten-Free Green Bean Casserole:

Verify that the cream of mushroom soup is gluten-free and switch to gluten-free fried onions for a dish suitable for those with gluten sensitivities.

Spicy Tex-Mex Green Bean Casserole:

Add 1 cup (150 grams) of diced jalapeños and substitute soy sauce with taco seasoning for a zesty kick, and top with crushed tortilla chips instead of traditional fried onions.

Tips on plating and presentation

To make your green bean casserole visually appealing, I recommend using a white or light-colored dish that contrasts beautifully against the vibrant greens of the beans.

For added texture, sprinkle some fried onions or fresh herbs on top just before serving.

Finally, consider adding a small side of lemon wedges for a pop of color and zest to brighten the plate!
