🥔 Why Russet Potatoes Work So Well
Russet potatoes are especially good for this casserole because they contain plenty of starch.
As they bake, that starch helps the potatoes become tender while also thickening the creamy sauce surrounding them.
The result is exactly what you want: potatoes that are soft and creamy inside, with a rich sauce clinging to every slice.
Try to choose potatoes that are similar in size so they cook at roughly the same rate.
🍳 Kitchen Tools You’ll Need
You don’t need much equipment.
- 9 × 13-inch glass casserole dish
- Sharp chef’s knife or mandoline
- Cutting board
- Mixing bowl
- Measuring cups
- Aluminum foil
- Spoon or rubber spatula
- Oven mitts
Pro tip
A mandoline makes quick work of slicing the potatoes and gives you wonderfully even pieces.
If you’re using one, be careful. The blade is extremely sharp.
If you don’t have a mandoline, a sharp knife works perfectly well. Just aim for slices around ⅛ inch (3 mm) thick.
👩🍳 How to Make This Easy Creamy Potato Casserole
1. Preheat the oven
Preheat your oven to 375°F (190°C).
Place the oven rack in the center position.
Lightly grease a 9 × 13-inch glass casserole dish.
You can use butter, cooking spray, or a thin coating of neutral oil.
2. Slice the potatoes
Wash and scrub the russet potatoes.
Peel them if you prefer a smoother casserole, although leaving the skins on is perfectly fine if they are clean and in good condition.
Slice the potatoes into thin, even rounds.
Aim for about ⅛ inch (3 mm) thick.
This is important.
If some slices are very thick and others are paper-thin, the thinner pieces may become extremely soft before the thick pieces are fully tender.
What should NOT happen: Don’t cut the potatoes into large chunks. This recipe relies on thin slices so the condensed soup can cook them evenly.
3. Layer the potatoes
Arrange a layer of sliced potatoes across the bottom of the casserole dish.
Try to overlap the slices slightly.
Sprinkle lightly with black pepper or garlic powder if using.
Add another layer of potatoes.
Continue until all the potatoes are in the dish.
Don’t worry if the layers aren’t perfect.
This is a rustic comfort-food casserole.
4. Add the condensed cream of chicken soup
Spoon the condensed cream of chicken soup over the raw potatoes.
Use the back of a spoon or rubber spatula to spread it as evenly as possible.
You don’t need to dilute the soup with water or milk for this version.
As the casserole cooks, moisture released from the potatoes combines with the condensed soup to create a creamy sauce.
This is one of the reasons the recipe is so easy.
Pro tip: Try to spread the soup toward the edges so the top layer of potatoes is not left completely uncovered.
5. Add the cheddar cheese
Sprinkle the shredded cheddar cheese evenly over the top.
Don’t be shy with it.
As the casserole bakes, the cheese melts into the creamy sauce and develops a beautiful golden surface.
Sharp cheddar is especially good because its stronger flavor stands up to the mild potatoes and cream soup.
6. Cover the casserole
Cover the dish tightly with aluminum foil.
This traps steam inside the casserole.
The steam is important because it helps cook the raw potatoes until they become tender.
Place the covered casserole in the preheated 375°F (190°C) oven.
Bake for approximately 50–60 minutes.
7. Check the potatoes
After about 50 minutes, carefully remove the foil.
Insert a thin knife or fork into the center of the casserole.
The potatoes should be starting to become tender.
If the knife meets significant resistance, cover the dish again and continue baking for another 10–15 minutes.
Potatoes vary in size and thickness, so don’t rely on the clock alone.
Visual cue: The sauce should be bubbling around the edges, and the potatoes should look soft rather than firm and white.
8. Uncover and finish baking
Once the potatoes are tender, remove the foil completely.
Return the casserole to the oven for another 15–20 minutes.
The cheddar should melt completely and become golden brown in spots.
The edges should bubble gently.
If you want a darker, more deeply browned cheese topping, switch the oven to broil for 1–2 minutes at the very end.
Watch it constantly.
Cheese can go from beautifully golden to burnt surprisingly quickly.
9. Let it rest
This is the hardest step because the casserole smells incredible.
Remove it from the oven and let it rest for 10–15 minutes.
During this time, the creamy sauce thickens slightly and settles around the potatoes.
Cutting into it immediately can make the sauce runny.
A short rest gives you a much more cohesive serving.
10. Serve warm
Scoop generous portions onto plates while the casserole is still warm.
You should see layers of tender potatoes coated in creamy chicken-flavored sauce, with melted cheddar stretching across the top.
For a simple finish, sprinkle with chopped parsley or chives.
👨🍳 Chef-Level Tips for Better Results
Slice the potatoes evenly
This is probably the most important detail.
Thin, uniform slices cook more evenly.
Don’t skip the foil
The covered baking stage creates the steam needed to soften the potatoes.
Without it, the cheese can brown before the potatoes are tender.
Don’t add too much soup
It may be tempting to pour in another can, but too much condensed soup can make the casserole overly salty and heavy.
Start with the recommended amount.
Use freshly shredded cheddar
Pre-shredded cheese is convenient, but freshly shredded cheddar usually melts more smoothly.
Let it rest
Those extra 10–15 minutes make a difference.
The sauce thickens and becomes easier to serve.
Season carefully
Condensed cream of chicken soup and cheddar cheese can both contain plenty of sodium.
Taste before adding salt.
In most cases, you may not need any additional salt at all.
⚠️ Common Mistakes to Avoid
The potatoes are still hard.
They were likely sliced too thick, or the casserole needed more covered cooking time.
Cover it again and continue baking until a knife slides easily through the center.
The cheese is burning.
The oven may be running hot, or the casserole was uncovered too early.
Cover the dish again while the potatoes finish cooking.
The casserole is watery.
This can happen if the potatoes release a lot of moisture or if extra liquid was added.
Let the casserole rest for 15–20 minutes after baking. The sauce will usually thicken as it cools slightly.
The center is cooked but the edges are dry.
The casserole may have been baked uncovered for too long.
Keep it covered during most of the cooking process and only uncover it for the final browning stage.
The casserole tastes too salty.
Avoid adding extra salt before tasting.
If the finished dish is already salty, serve it alongside simple, lightly seasoned vegetables or protein.
🌟 Easy Variations
The basic three-ingredient recipe is delicious, but you can easily turn it into something more elaborate.
Garlic Cheddar Potatoes
Add 1 teaspoon garlic powder between the potato layers.
The garlic gives the creamy sauce a deeper savory flavor.
Bacon Cheddar Potato Casserole
Cook and crumble 6–8 slices of bacon.
Sprinkle half between the potato layers and half over the cheese before baking.
The smoky bacon is an excellent match for the creamy chicken soup.
French Onion Style
Add 1 cup (150 g) caramelized onions between the potato layers.
Top with cheddar or a mixture of cheddar and Swiss cheese.
Herb Potato Casserole
Add dried thyme, parsley, and black pepper.
Finish with fresh chives.
This version feels especially nice alongside roast chicken or turkey.
Spicy Cheddar Potatoes
Add ½ teaspoon cayenne or 1 teaspoon crushed red pepper flakes.
For more heat, add diced jalapeños.
Broccoli Cheddar Version
Add approximately 2 cups (180 g) lightly steamed broccoli florets between the potato layers.
The combination turns the casserole into a heartier vegetable side dish.
Chicken and Potato Casserole
For a more complete meal, add 2 cups (280 g) cooked shredded chicken between the potato layers.
This transforms the simple side dish into a filling family dinner.
🥘 Can You Turn This Into a Full Meal?
Absolutely.
The basic recipe works beautifully as a side dish, but adding cooked chicken makes it much more substantial.
You can also serve the potato casserole alongside:
- Roast chicken
- Baked chicken breasts
- Meatloaf
- Roast beef
- Ham
- Pork chops
- Grilled steak
- Green beans
- Roasted carrots
- Simple garden salad
For a comforting Sunday dinner, serve it with roast chicken, green beans, and a crisp salad.
For a holiday meal, it makes a wonderful alternative to traditional scalloped potatoes.
🧊 Storage & Reheating Guide
Refrigerator
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate for 3–4 days.
Oven reheating
For the best texture, place the casserole in an oven-safe dish.
Cover loosely with foil and heat at 350°F (175°C) for approximately 20–30 minutes, or until hot throughout.
Remove the foil during the final few minutes if you want the cheese topping to crisp again.
Microwave
Individual portions can be microwaved for approximately 1–3 minutes, depending on the serving size and microwave power.
Cover loosely to prevent splattering.
The microwave will soften the cheese and potatoes slightly, but it is convenient for lunch.
Freezing
Because potatoes can change texture after freezing, this casserole is best enjoyed fresh or refrigerated.
If you do freeze it, expect the potatoes to become somewhat softer after thawing.
For the best quality, use frozen leftovers within 1–2 months.

💡 Did You Know?
Condensed cream soups became a popular shortcut in American home cooking because they could act as both a sauce and a flavor base.
Instead of making a roux, measuring broth, and preparing a cream sauce from scratch, a single can can provide much of the richness needed for a casserole.
That is exactly what makes this potato dish so practical.
The soup does the heavy lifting.
The potatoes provide the hearty texture.
The cheese brings the irresistible golden finish.

❓ Frequently Asked Questions
Can I put raw potatoes directly into a casserole?
Yes. Thinly sliced raw potatoes can cook directly in the casserole as long as they have enough moisture and sufficient covered cooking time. The foil helps trap steam and allows the potatoes to become tender.
Do I need to dilute condensed cream of chicken soup?
Not for this recipe. The raw potatoes release moisture as they cook, which combines with the condensed soup to create a creamy sauce.
How thin should I slice the potatoes?
Aim for approximately ⅛ inch (3 mm). Thin, even slices cook more reliably than thick slices.
Can I use another type of potato?
Yes. Yukon Gold potatoes are an excellent substitute and will produce a naturally buttery flavor. Russets are particularly good if you want a soft, creamy texture.
Can I make this casserole ahead of time?
Yes, but for the best texture, assemble it close to baking time. If preparing ahead, cover it tightly and refrigerate it, then allow some extra baking time because the potatoes will be cold.
Can I add meat to this potato casserole?
Definitely. Cooked shredded chicken, diced ham, cooked bacon, or leftover roast chicken can turn it into a hearty main dish.
Why do I need to cover the casserole?
Covering traps steam and helps cook the raw potatoes. Without that moisture, the potatoes may remain firm while the cheese becomes overly browned.
