Creamy and comforting, these cottage cheese scalloped potatoes combine tender potato slices with a smooth, savory cheese sauce and a golden cheddar topping. They’re simple to assemble, reliable for family dinners, and ideal alongside roasted meats or holiday mains.

Scalloped potatoes are always welcome when you need a cozy side dish, and this version gives the classic casserole a slightly different creamy base. Blended cottage cheese disappears into the sauce, helping create a smooth consistency without leaving noticeable curds between the potato layers.
The sauce starts with olive oil and flour before low-fat milk is added gradually for a thick, pourable texture. Garlic powder brings savory depth, while a small amount of cayenne adds gentle warmth rather than overwhelming heat.
Once everything is layered in a casserole dish, the oven handles the rest. After about an hour, you get tender potatoes underneath a bubbly, lightly browned cheese topping that works especially well for Sunday dinners, potlucks, and holiday meals.
Ingredients
You only need a relatively short list of ingredients to build this creamy potato casserole.
White potatoes: Thinly sliced potatoes form the layers of the dish and become tender as they slowly bake in the sauce.
Cottage cheese: Blend it completely smooth before adding it to the sauce so you get creaminess without visible cottage cheese curds.
Low-fat milk: Creates the liquid base for the sauce and helps the potatoes cook while the casserole bakes.
All-purpose flour: Thickens the milk mixture so the sauce coats the potatoes instead of settling thinly at the bottom of the baking dish.
Extra-virgin olive oil: Combines with the flour to form the roux and can also be used to lightly grease the casserole dish.
Garlic powder: Adds simple savory flavor throughout the creamy sauce.
Cayenne pepper: Gives the casserole a subtle background warmth. The amount is small enough that it should not make the potatoes aggressively spicy.
Sea salt: Seasons the potatoes indirectly through the sauce.
Shredded cheddar or Colby cheese: Melts across the top and creates the golden, cheesy finish.
Nacho cheddar popcorn seasoning: Adds another savory cheese note to the surface of the casserole before baking.

Cooking Steps
STEP 1: Heat your oven to 350°F (175°C). Lightly coat a casserole dish with olive oil so the potato slices release more easily after baking. Peel the potatoes and cut them into thin, fairly uniform slices.
STEP 2: Blend the cottage cheese until completely smooth. Taking the time to remove the curds is important because it allows the cottage cheese to blend naturally into the finished cream sauce.
STEP 3: Warm the olive oil in a skillet or saucepan over medium heat. Stir in the flour and continue mixing until it forms a smooth roux. You want the flour evenly incorporated without allowing it to become deeply browned.
STEP 4: Gradually pour in the milk while stirring continuously. Add the salt, garlic powder, and cayenne. Continue cooking briefly until the mixture is smooth and begins to thicken enough to lightly coat your spoon.
STEP 5: Reduce the heat and stir the blended cottage cheese into the milk mixture. Keep stirring until the sauce looks uniform and creamy. Avoid aggressively boiling it once the cottage cheese has been incorporated.
STEP 6: Arrange about half of the sliced potatoes across the bottom of your prepared casserole dish. Spoon half of the creamy sauce over them, spreading it so the potatoes are evenly covered. Add the remaining potatoes followed by the rest of the sauce.
STEP 7: Sprinkle the shredded cheddar or Colby evenly over the surface, then finish with the nacho cheddar seasoning. Bake for about 1 hour, or until the potatoes are tender when pierced and the top has developed a golden finish.
STEP 8: Remove the casserole from the oven and let it stand briefly before cutting into portions. Resting allows the hot sauce to settle slightly around the potato layers and makes the finished dish easier to serve.
What to Serve with Cottage Cheese Scalloped Potatoes
These creamy potatoes are rich enough to complement simple main dishes without needing complicated sides.
- Roasted chicken: Mild roasted chicken works especially well with the creamy garlic and cheese flavors in the potatoes.
- Baked ham: The salty, savory flavor of ham is a natural match for soft scalloped potatoes, making this combination particularly useful for holiday meals.
- Roasted vegetables: Green beans, broccoli, asparagus, or Brussels sprouts provide a lighter vegetable side alongside the creamy casserole.
Can I slice the potatoes ahead of time?
You can prepare the potatoes a little ahead, but raw potato slices can discolor after they are exposed to air. If you need to slice them early, keep them submerged in cold water, then drain and dry them thoroughly before assembling the casserole so you do not introduce excess water into the sauce.
Do I need to blend the cottage cheese?
Blending is strongly recommended for this dish. Smooth cottage cheese incorporates much more evenly into the milk sauce and gives the casserole a consistency closer to traditional creamy scalloped potatoes. Unblended cottage cheese will leave noticeable curds throughout the finished layers.
How do I know when scalloped potatoes are done?
Check the center of the casserole rather than relying only on the browned cheese topping. Slide a thin knife into several potato slices near the middle. It should move through them easily with very little resistance. If the potatoes still feel firm, give the casserole additional baking time.
Can I prepare the casserole before baking?
Yes. You can assemble the potato layers and sauce ahead of time, cover the baking dish, and refrigerate it until you are ready to bake. Because a chilled casserole begins at a lower temperature, it may require additional oven time before the potatoes become completely tender.

What if my potato slices are thicker?
Thicker potatoes generally need longer to cook. Thin, evenly sized slices are especially important in scalloped potatoes because they allow all the layers to soften at approximately the same rate. If some pieces are noticeably thicker than others, you may end up with a mixture of tender and firm potatoes.
Helpful Tips
- Keep the slices consistent. A mandoline can make uniform slices quickly, but a sharp knife works perfectly well if you take your time. Consistent thickness is more important than making the slices extremely thin.
- Add the milk gradually. Slowly whisking or stirring the milk into the flour mixture helps prevent lumps and gives you a smoother sauce before the cottage cheese goes in.
- Test the middle before serving. The top can become beautifully golden while potatoes in the center are still slightly firm, so always test a center slice for tenderness.
Keeping Leftovers Fresh
Let leftover scalloped potatoes cool before transferring them to an airtight container or covering the baking dish tightly. Refrigerate them promptly and use them within about 3 to 4 days.
To reheat a larger portion, place it in an oven-safe dish, cover it loosely, and warm it at about 350°F until heated through. Covering the potatoes for most of the reheating time helps keep the creamy sauce from drying out. You can uncover them toward the end if you want to refresh the cheesy surface.
For individual portions, the microwave is convenient. Heat in short intervals until the center is hot, allowing the potatoes to rest briefly between intervals so the heat distributes more evenly.
Freezing is possible, although creamy potato dishes can change texture after thawing. Potatoes sometimes become softer or slightly grainy, and dairy-based sauces can separate. For the most consistent texture, this casserole is better refrigerated rather than frozen.
Whether you serve it beside a weeknight roast or add it to a larger holiday spread, this potato casserole delivers the familiar comfort of scalloped potatoes with a smooth cottage cheese-based sauce. The most important details are slicing the potatoes evenly, blending the cottage cheese thoroughly, and giving the casserole enough oven time for every layer to become tender.
