Step-by-Step Cooking Instructions
Step 1: Preheat your oven to 375°F and lightly butter a large casserole dish to prevent sticking.
Step 2: Place the cubed potatoes in a large pot of salted water and boil for about ten minutes until slightly tender but not fully cooked.
Step 3: While the potatoes cook, steam the green beans for five minutes until bright green and slightly crisp.
Step 4: Drain both the potatoes and green beans and transfer them to a large mixing bowl to cool slightly.
Step 5: In a separate bowl, whisk together cream of mushroom soup, milk, melted butter, garlic powder, onion powder, salt, and black pepper until well combined.
Step 6: Pour the creamy mixture over the potatoes and green beans, then gently toss everything together until evenly coated.
Step 7: Transfer the mixture into the prepared baking dish, spreading it out in an even layer.
Step 8: Sprinkle shredded cheddar cheese generously over the top, covering the surface completely for a rich, cheesy crust.
Step 9: Bake the casserole for about 30 minutes, or until the sauce is bubbling and the cheese has melted beautifully.
Step 10: Remove from the oven, top with crispy fried onions, and bake for an additional five minutes until golden brown, then allow it to rest before serving.
Tips for Customizing the Recipe
Green bean and potato casserole is very versatile and can be tailored to suit your taste. For added richness, stir in a few spoonfuls of sour cream or cream cheese into the sauce before baking. If you want to add more protein, mix in cooked bacon, sausage, or shredded chicken. For a vegetarian twist, try adding sautéed mushrooms or caramelized onions for deeper flavor. A sprinkle of paprika or crushed red pepper gives it a gentle kick, while using a blend of cheeses like mozzarella or Monterey Jack can create a creamier texture. Substituting sweet potatoes for regular ones offers a sweeter, earthy touch that pairs wonderfully with the green beans.
Nutritional Information
Each serving of green bean and potato casserole provides around 360 to 420 calories, depending on portion size and ingredients used. It contains a balanced mix of carbohydrates from the potatoes, fiber from the green beans, and protein from the cheese. The creamy sauce contributes to its rich taste while still offering valuable calcium from the dairy ingredients. To make the casserole lighter, you can use low-fat milk, reduced-fat cheese, or a lighter cream soup. Despite being a comfort dish, it remains relatively wholesome when enjoyed in moderation, making it a great choice for family meals.
Serving Suggestions

Green bean and potato casserole shines both as a main dish and a hearty side. It pairs beautifully with roasted chicken, baked salmon, or grilled steak for a complete dinner.

Leftovers can be reheated easily and often taste even better the next day as the flavors deepen. It also makes an excellent contribution to potlucks or gatherings since it can be prepared ahead and baked just before serving.
