Ingredients
For the Casserole

For the Topping
- 1 ½ cups crispy fried onions
- ¼ teaspoon garlic powder (optional, for extra taste)
Kitchen Tools Needed
Before you start cooking, gather these essential kitchen tools:
- Mixing bowl – To combine the sauce and seasonings.
- Measuring cups and spoons – For accurate ingredient measurements.
- Baking dish (9×13 inches recommended) – To bake the casserole evenly.
- Wooden spoon or spatula – For mixing everything together.
- Can opener – If you’re using canned green beans.
- Oven mitts – To safely handle the hot baking dish.
Having everything ready will make the cooking process smooth and stress-free!
Cooking Instructions
- Preheat the oven to 350°F (175°C). This ensures your casserole bakes evenly.
- Prepare the sauce – In a large mixing bowl, combine the cream of mushroom soup, milk, salt, black pepper, and garlic powder (if using). Stir until smooth.
- Add the green beans – Gently fold the cooked green beans into the sauce mixture, making sure they are evenly coated. If you’re adding cheese, mix it in now.
- Transfer to a baking dish – Pour the mixture into a greased 9×13-inch baking dish, spreading it out evenly.
- Bake the casserole – Place the dish in the oven and bake for 25 minutes, or until the mixture is hot and bubbling.
- Add the crispy onions – Sprinkle the fried onions on top, then bake for another 5-10 minutes until golden brown.
- Let it cool slightly – Remove from the oven and allow the casserole to sit for a few minutes before serving.

Tips and Tricks for Success
- Use fresh or frozen green beans for the best texture. Canned green beans work, but fresh ones add a nice bite. Blanch fresh beans in boiling water for 3-5 minutes before using.
- Don’t skip the crispy onions! They add the perfect crunch and flavor. If you love extra crispiness, mix some into the casserole before baking.
- Customize to your taste. Add shredded cheese for a richer dish, or toss in cooked bacon or sautéed mushrooms for extra flavor.
- Make it ahead. Assemble the casserole without the fried onions and refrigerate for up to a day. When ready to serve, bake, then add the onions at the end.
- Adjust seasoning as needed. If using canned green beans, rinse them first to remove extra salt. Taste the mixture before baking and adjust the salt if necessary.
Now that you have all the details, you’re ready to make the best green bean casserole ever! Serve it as a side dish at your next gathering, and watch it disappear quickly.
Ingredient Substitutions and Variations
Want to switch things up? Here are some easy substitutions and variations to fit your taste or dietary needs:
- Green Beans: Fresh, frozen, or canned all work! If using fresh, blanch them in boiling water for 3-5 minutes before baking.
- Cream of Mushroom Soup: Swap it with cream of chicken, cream of celery, or make a homemade version by combining milk, butter, and sautéed mushrooms.
- Milk: Use heavy cream for a richer texture or swap with almond, soy, or oat milk for a dairy-free option.
- Fried Onions: Try crushed crackers, panko breadcrumbs, or homemade crispy shallots for a different crunch.
- Cheese Lovers: Add shredded cheddar, mozzarella, or parmesan for extra creaminess and flavor.
- Extra Flavor Boosts: Add cooked bacon, sautéed mushrooms, or a dash of Worcestershire sauce to enhance the taste.
