How to Make Hamburger Scalloped Potato Green Bean Casserole
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a large casserole or baking dish.
Step 2: Prepare the Potatoes
Wash and peel the potatoes if desired.
Cut them into thin, even slices.
Keeping the slices approximately the same thickness is important because it helps all the potatoes cook at the same rate.
A mandoline slicer works particularly well, but a sharp knife is perfectly fine.
Step 3: Brown the Hamburger
Place a large skillet over medium-high heat.
Add the ground beef and cook, breaking it into small crumbles.
Continue cooking until the beef is completely browned.
Step 4: Add the Onion
Add the diced onion to the beef.
Cook until the onion becomes tender and translucent.
Step 5: Add the Garlic
Stir in the minced garlic.
Cook briefly until fragrant.
Step 6: Drain the Beef
Carefully drain excess grease from the skillet.
This prevents the finished casserole from becoming overly greasy.
Season the beef with garlic powder, onion powder, paprika, salt, and black pepper.
Step 7: Prepare the Creamy Sauce
In a mixing bowl, combine the cream of mushroom soup, milk, and sour cream.
Stir until smooth.
Add about half of the shredded cheddar cheese and mix again.
Taste and lightly season with black pepper if desired.
Step 8: Prepare the Green Beans
If using canned green beans, drain them thoroughly.
If using frozen green beans, thaw them first and remove excess moisture.
Fresh green beans can also be used, but briefly cooking them beforehand helps ensure they’re tender when the casserole is finished.
Step 9: Start Layering
Arrange a layer of thinly sliced potatoes across the bottom of the prepared baking dish.
Slightly overlapping the slices works well.
Step 10: Add the Hamburger
Spoon some of the seasoned ground beef and onion mixture over the potatoes.
Spread it evenly.
Step 11: Add Green Beans
Scatter a layer of green beans over the beef.
Try to distribute them evenly so every serving contains some.
Step 12: Add the Creamy Sauce
Spoon some of the creamy mushroom and cheese mixture over the vegetables and beef.
Spread gently across the layer.
Step 13: Repeat the Layers
Continue layering potatoes, beef, green beans, and sauce until the ingredients have been used.
Finish with potatoes and enough sauce to keep the top layer moist while baking.
Step 14: Cover and Bake
Cover the baking dish tightly with aluminum foil.
Bake for approximately 50–60 minutes, or until the potatoes are becoming tender.
The exact cooking time will depend heavily on how thinly the potatoes are sliced.
Step 15: Check the Potatoes
Carefully remove the foil and insert a thin knife into the center of the casserole.
The potatoes should be easily pierced.
If they’re still firm, cover the casserole again and continue baking.
Step 16: Add the Cheese
Once the potatoes are tender, sprinkle the remaining shredded cheddar over the top.
Return the casserole to the oven uncovered.
Step 17: Finish Baking
Bake for another 10–15 minutes, or until the cheese has melted and the sauce is bubbling around the edges.
For extra crunch, add French-fried onions during the final few minutes.
Step 18: Let It Rest
Remove the casserole from the oven and allow it to rest for about 10 minutes.
Resting gives the creamy sauce time to thicken and makes the casserole much easier to serve.
Step 19: Garnish and Serve
Sprinkle with dried or fresh parsley.
Spoon generous portions onto plates and serve warm.

Frequently Asked Questions
What potatoes work best?
Russet potatoes become wonderfully soft and creamy.
Yukon Gold potatoes are another excellent choice because they have a naturally buttery flavor and hold their shape slightly better.
Do I need to peel the potatoes?
No.
You can leave the skins on, particularly when using Yukon Gold potatoes.
Just scrub them thoroughly before slicing.
How thin should the potatoes be?
Thin and uniform slices are best.
Thick potato slices take significantly longer to become tender and can leave you with a casserole that’s bubbling around the edges but still firm in the center.
Can I use canned green beans?
Absolutely.
Drain them thoroughly before adding them to the casserole.
Can I use frozen green beans?
Yes.
Thaw and drain them first so they don’t add too much extra liquid.
Can I substitute the cream of mushroom soup?
Yes.
Cream of chicken or cream of celery soup can work well.
Can I add more cheese?
Definitely.
Cheddar, Monterey Jack, Pepper Jack, mozzarella, or a combination can all be used.
Why are my potatoes still hard?
They may have been sliced too thickly or the casserole may simply need additional covered baking time.
Keep it covered so the trapped steam helps soften the potatoes.
Can I prepare this ahead?
Yes.
You can prepare many of the components ahead, refrigerate them, and assemble before baking.
If assembling the entire casserole in advance, keep the potatoes completely covered by the sauce to minimize discoloration.
Can I use ground turkey?
Yes.
Ground turkey or ground chicken can replace the hamburger. Cook it completely before assembling the casserole.
20 Detailed Tips for the Best Casserole

Add garlic for extra savory flavor.
Drain green beans thoroughly.
Mix the sauce until completely smooth.
Don’t use too much salt before tasting the sauce.
Keep the potatoes surrounded by enough sauce.
Cover the casserole tightly during the first stage of baking.
Don’t remove the foil too early.
Test potatoes in the center rather than around the edges.
Give firm potatoes additional covered baking time.
Add the final cheese only after the potatoes are nearly tender.
Use French-fried onions for a crunchy finish.
Let the casserole rest before serving.
Add a splash of milk when reheating if it seems dry.
Garnish with parsley for a simple finishing touch.

Extra-Cheesy Green Bean Casserole

Storage & Reheating
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate for up to 3–4 days.
Reheat individual servings in the microwave until hot throughout.
For larger portions, cover the casserole and warm it in the oven. Adding a small splash of milk or extra sauce can help restore the creamy consistency.
Make-Ahead Tips
The ground beef can be browned and seasoned a day ahead.
The green beans can also be prepared and the creamy sauce mixed in advance.
Store everything separately in the refrigerator.
For the best results, slice the potatoes closer to assembly time. This prevents them from discoloring and helps maintain their texture.
Once assembled, bake until the potatoes are completely tender and finish with the cheese topping.
Why This Recipe Works
This casserole combines several classic comfort-food ingredients in one dish.
Ground beef provides a rich, savory base. Thinly sliced potatoes absorb the creamy sauce while baking and develop the soft texture associated with scalloped potatoes.
Green beans balance the richness with vegetable flavor and texture, while cream of mushroom soup, sour cream, and melted cheddar create a creamy sauce that holds everything together.
The final layer of melted cheese transforms the simple ingredients into a bubbling, hearty casserole that’s easy to portion and satisfying enough to serve as the main meal.
This Hamburger Scalloped Potato Green Bean Casserole is creamy, cheesy, beefy, and wonderfully comforting—the kind of easy family dinner that’s especially good when you’re craving a warm, old-fashioned casserole.
