Ingredients
2 cans (10.5 oz each) condensed cream of mushroom soup
2/3 cup whole milk
1 teaspoon soy sauce
1/2 teaspoon garlic powder
1/4 teaspoon black pepper
4 cups cut green beans, drained if canned or thawed if frozen
1 1/2 cups crispy fried onions, divided

Step-by-Step Instructions (Detailed)
- Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish so the casserole doesn’t stick and is easy to serve.
- In a large mixing bowl, whisk together the condensed cream of mushroom soup, milk, soy sauce, garlic powder, and black pepper until the mixture is smooth and well combined. This creates the creamy base that coats every green bean.
- Add the green beans to the bowl and stir until they are completely covered in the creamy sauce. Make sure there are no dry spots so the casserole bakes evenly.
- Fold in 1 cup of the crispy fried onions, reserving the remaining 1/2 cup for the topping. Mixing some onions inside the casserole adds extra flavor and texture in every bite.
- Transfer the green bean mixture to the prepared baking dish and spread it into an even layer so it bakes and bubbles uniformly.
- Bake the casserole, uncovered, for 25 minutes or until the edges are bubbly and the center is hot. If your oven runs cool, you may need an extra 3–5 minutes.
- Carefully remove the dish from the oven and give the casserole a gentle stir to redistribute the sauce. Sprinkle the remaining 1/2 cup of crispy fried onions evenly over the top for a crunchy golden crust.
- Return the casserole to the oven and bake for another 5–8 minutes, just until the fried onions on top are deep golden brown but not burned.
- Let the casserole rest for 5 minutes before serving. This short rest helps the sauce thicken slightly so each scoop holds together beautifully on the plate. Serve warm alongside turkey, ham, or any comfort-food main dish.
Pro Tips
Use frozen green beans for extra texture if you prefer a slight snap; canned green beans give a softer, classic holiday feel.
Make it ahead by assembling the casserole without the final onion topping, refrigerating up to 24 hours, then baking and adding the topping just before serving.
For a flavor boost, stir in 1/2 cup shredded cheddar cheese or a handful of chopped cooked bacon before baking.
