Scalloped potatoes without cheese are a creamy, comforting side dish made with thin red potatoes, tender onions, butter, flour, and warm milk. They bake into soft layers with a thick sauce and lightly golden top, making them dependable for holidays, Sunday dinners, or simple family meals.
When you want a classic potato casserole without relying on cheddar or other cheeses, this version keeps things wonderfully simple. The potatoes slowly absorb the buttery milk sauce as they bake, while thin slices of onion add savory flavor throughout every layer.
The method also works because the flour is distributed between the potatoes instead of being cooked into a separate sauce first. As the casserole heats, the flour combines with the butter and milk to form a creamy sauce right inside the baking dish.
It is especially useful when your oven is already doing most of the work for dinner. Once the potatoes are sliced and layered, the casserole can bake mostly unattended until the potatoes are fork-tender and the surface is gently browned.
Ingredients
Red potatoes: Thinly sliced red potatoes form the hearty base of the casserole. Cutting them to about 1/8 inch helps them become tender at roughly the same time.
Onions: Thinly sliced onions soften between the potato layers and add savory flavor without overpowering the simple cream sauce.
Whole milk: Warm milk provides the liquid for the sauce. Whole milk gives the finished potatoes a richer, smoother consistency.
Salted butter: Butter adds richness and combines with the milk and flour while the casserole bakes.
All-purpose flour: Flour thickens the milk into a creamy sauce as the dish cooks.
Salt: A generous but balanced amount of salt seasons the potatoes throughout their layers.
Black pepper: Freshly ground pepper gives the mild cream sauce a little warmth and keeps the flavor from tasting flat.
Cooking Steps
STEP 1: Heat your oven to 350°F. Peel the red potatoes, then slice them into rounds about 1/8 inch thick. A mandoline makes this particularly quick, but a food processor slicing attachment or sharp knife also works. Halve the onions and slice them into thin, even half-rounds.
STEP 2: Warm the milk gently in a saucepan over medium heat. It should become hot but should not reach a boil. Stir it occasionally to keep the bottom from scorching. Starting with warm milk encourages the casserole to heat evenly once it goes into the oven.
STEP 3: Arrange about one-third of the sliced potatoes across the bottom of a 13 x 9-inch baking dish, overlapping them slightly where needed. Scatter one-third of the onions evenly over the potatoes. Sprinkle part of the flour over this layer, dot it with butter, and season with some of the salt and pepper.
STEP 4: Add another layer using one-third of the potatoes and onions. Sprinkle with the remaining portion of flour intended for the middle layers, add another portion of butter, and season again. Keeping the flour reasonably even is important because it will thicken the milk surrounding the potatoes.
STEP 5: Finish with the remaining potatoes and onions. Dot the final butter over the surface and add the remaining salt and black pepper. Slowly pour the warm milk over the entire casserole, moving around the dish as you pour so the liquid reaches all of the layers.
STEP 6: Bake uncovered for 60 to 80 minutes. The casserole is ready when a fork or thin knife slides easily through the center potatoes and the sauce has thickened around the edges. If the surface browns too quickly, cover it loosely with foil for the remaining baking time. Let the casserole rest for about 5 minutes before serving so the hot sauce can settle and thicken slightly.
What to Serve with Scalloped Potatoes Without Cheese
These potatoes have a mild, creamy flavor, which makes them flexible enough to accompany plenty of main dishes.
Roast chicken: A simply seasoned roast chicken is an excellent pairing because its savory juices complement the creamy potatoes without making the meal overly heavy.
Baked ham: Scalloped potatoes are especially good alongside ham for holiday dinners or larger family gatherings. The salty, savory meat balances the mild potato and onion layers.
Roasted vegetables: Serve them with green beans, Brussels sprouts, asparagus, or another roasted green vegetable when you want additional color and a fresher contrast on the plate.
Can scalloped potatoes really be creamy without cheese?
Yes. Cheese is not necessary for a creamy scalloped potato casserole. In this version, milk, butter, and flour create the sauce while the potatoes bake. The natural starch released by the sliced potatoes contributes additional body, giving you a creamy result without adding shredded cheese.
How do I know when scalloped potatoes are fully cooked?
Test the potatoes near the center of the baking dish rather than judging them only by the browned surface. Insert a fork or thin knife into several potato slices. It should slide through with very little resistance. If the potatoes still feel firm, continue baking even if the top already looks golden.
Why are my scalloped potatoes still firm?
Potatoes can remain firm when the slices are too thick, the casserole has not baked long enough, or the liquid has not heated sufficiently. Aim for slices about 1/8 inch thick and allow the full 60 to 80 minutes of baking time. Cover the top loosely with foil if additional cooking time is needed.
Should scalloped potatoes be covered while baking?
This version is designed to bake uncovered so the top can develop a lightly golden finish. If the surface becomes dark before the center potatoes are tender, loosely cover the baking dish with aluminum foil and continue cooking until the potatoes are soft.
Can I prepare scalloped potatoes ahead of time?
You can assemble the potatoes a little ahead, but potatoes can discolor after slicing when exposed to air. For the most attractive result, it is better to assemble the casserole relatively close to baking time. Fully cooked leftovers are also convenient because they reheat well for another meal.
Helpful Tips
- Keep your slices consistent. Potatoes that vary significantly in thickness will cook at different speeds. Uniform 1/8-inch rounds give you the most dependable tender texture.
- Pour the milk slowly. Adding the warm milk gradually across the entire surface helps distribute it between the potato layers rather than concentrating it in one section of the dish.
- Check the center before removing the casserole. Browning is not a reliable indication that the potatoes underneath are finished. Always test several slices near the middle of the baking dish for tenderness.
How to Store & Reheat
Allow leftover scalloped potatoes to cool before transferring them to an airtight container or covering the baking dish tightly. Store them in the refrigerator for up to 3 to 4 days.
For individual servings, reheating in the microwave is the quickest option. Heat in short intervals until the center is thoroughly hot. If the sauce has become especially thick after refrigeration, adding a very small splash of milk before reheating can help restore some of its creamy consistency.
For several portions, place the potatoes in an oven-safe dish, cover them with foil to limit moisture loss, and warm them in a moderate oven until heated through. Remove the foil toward the end if you want to refresh the lightly browned surface.
Scalloped potatoes can also be frozen, although freezing and thawing may make the potato texture somewhat softer and the milk sauce less smooth. If you decide to freeze leftovers, portion the cooled casserole into airtight freezer containers and use it within about 1 to 2 months. Thaw overnight in the refrigerator before reheating.
This simple casserole proves that scalloped potatoes do not need cheese to feel rich and satisfying. Thin red potatoes, mellow onions, warm milk, butter, and flour come together in the oven to create tender layers surrounded by a classic creamy sauce. Give the casserole enough time to bake until completely tender, then allow that brief resting period before serving for the smoothest, most cohesive result.
Scalloped Potatoes Without Cheese
Ingredients
- 4.3 cups milk warmed; whole milk produces a richer, creamier consistency
- 1 1/2 teaspoons freshly ground black pepper
- 8 –10 medium red potatoes peeled and sliced into approximately 1/8-inch rounds
- 1/2 cup salted butter
- 3 onions halved and cut into thin, even slices
- 6 tablespoons all-purpose flour
- 2 1/2 teaspoons salt
Instructions
- Preheat the oven to 350°F (176°C).
- Wash the red potatoes thoroughly, then remove the skins.
- Cut the potatoes into uniform rounds approximately 1/8 inch thick using a mandoline, food processor, or sharp knife.
- Halve the onions and slice them into evenly sized half-rounds so they cook consistently with the potatoes.
- For the most uniform texture, keep both the potato and onion slices thin and consistent in thickness.
- Place the milk in a saucepan over medium heat and warm it gently until hot, taking care not to let it boil.
- Stir the milk from time to time so it does not scorch on the bottom of the pan.
- Although warming the milk is optional, doing so can encourage more even cooking and help produce a smoother finished sauce.
- Arrange one-third of the sliced potatoes evenly across the bottom of a 13 × 9-inch casserole dish.
- Distribute one-third of the sliced onions over the potatoes.
- Scatter half of the flour across the vegetables, dot the layer with one-third of the butter, and season with one-third of the salt and black pepper.
- Create the second layer with another one-third of the potatoes and onions. Add half of the remaining flour, another one-third of the butter, and another one-third of the salt and pepper.
- Finish with the remaining potatoes and onions, then distribute the remaining butter over the surface.
- Season the top with the final portion of salt and pepper.
- An additional small pinch of black pepper may be scattered over the uppermost layer for a slightly stronger pepper flavor.
- Slowly pour the warmed milk evenly over the assembled potato and onion layers.
- Transfer the casserole to the preheated oven and bake uncovered for 60–80 minutes, or until the potatoes are easily pierced with a fork and the surface has developed a golden-brown color.
- If the top begins to brown before the potatoes become tender, loosely cover the casserole with aluminum foil to protect the surface from becoming overly dark.
- For a crisper finish, the casserole may be placed under the broiler for 1–2 minutes at the conclusion of baking.
- Remove the casserole from the oven and allow it to stand for approximately 5 minutes. This resting period gives the sauce time to thicken slightly and allows the flavors to settle.
