Ingredients You’ll Need

Potatoes and base

2 ½ pounds russet potatoes, peeled and thinly sliced (about 1/8 inch)
- Yukon Gold potatoes also work and give a slightly buttery flavor.
2 tablespoons unsalted butter, plus extra for greasing the dish
1 tablespoon olive oil
1 small yellow onion, very thinly sliced
3 cloves garlic, minced

Dairy and cheese

2 cups whole milk, warmed
- You can use 2% milk, but the sauce turns slightly less rich.
1 cup heavy cream
- Half and half works in a pinch, though the sauce thickens a bit less.
2 cups shredded sharp cheddar cheese, packed
- I prefer block cheddar that I shred myself, since pre-shredded often includes starch that affects melting.
1 cup shredded Gruyère or Swiss cheese
- Gruyère gives a nutty flavor; Swiss works as a budget swap.
¼ cup grated Parmesan cheese
- Use real Parmigiano Reggiano if possible for deeper flavor.

Seasonings

1 ½ teaspoons kosher salt, plus more to taste
½ teaspoon freshly ground black pepper
½ teaspoon smoked paprika or regular paprika
½ teaspoon dried thyme or 1 teaspoon fresh thyme leaves
¼ teaspoon ground nutmeg (optional, but adds a cozy note)

Pantry shortcuts and substitutions

Use pre-sliced deli potatoes from the refrigerated section if you feel short on time, though fresh slices hold texture better.
Use a bagged shredded cheese blend labeled “mac and cheese” or “triple cheddar” if you want a shortcut, but stir in at least some freshly grated Parmesan for flavor.
Use garlic powder and onion powder if you do not have fresh onion and garlic; start with ½ teaspoon each and adjust to taste.

Equipment list

9×13 inch baking dish or similar casserole dish
Large skillet or saucepan
Sharp chef’s knife or mandoline for even potato slices
Cutting board
Whisk
Measuring cups and spoons
Aluminum foil

Tips & Tricks

Slice potatoes evenly at about 1/8 inch thickness so they cook at the same rate and stay tender.
Warm the milk and cream before you add them to the pan so the sauce thickens smoothly and does not seize.
Shred cheese from a block to get a smoother melt and avoid grainy sauce.
Layer potatoes in overlapping shingle-style rows so the sauce flows between slices and coats everything.
Taste the cheese sauce before you pour it over the potatoes and adjust salt and pepper; bland sauce means bland casserole.
Cover the dish with foil for the first part of baking so the potatoes soften, then remove the foil to brown the top.
Let the casserole rest 10 to 15 minutes after baking so the sauce thickens and slices hold together.
Use a mandoline carefully if you want super even slices; wear a cut-resistant glove or stop before you reach the end of the potato.

How to Make Tasty Cheesy Scalloped Potatoes Recipe

Step 1: Prep the potatoes and pan

Grease a 9×13 inch baking dish with butter and set it aside. Peel the potatoes and slice them into thin rounds about 1/8 inch thick, then place them in a large bowl of cold water to keep them from browning. Pat the slices dry with a clean towel before layering so the sauce does not water down.

Step 2: Sauté onion and garlic

Heat the butter and olive oil in a large skillet over medium heat. Add the sliced onion and cook until it softens and turns translucent, about 5 to 7 minutes, while you stir occasionally. Add the minced garlic and cook 1 minute more until it smells fragrant, then lower the heat slightly.

Step 3: Build the creamy cheese sauce

Sprinkle in the salt, pepper, paprika, thyme, and nutmeg and stir them into the onion and garlic. Pour in the warmed milk and cream while you whisk so everything combines smoothly. Let the mixture heat until it gently simmers, then slowly stir in the cheddar, Gruyère, and Parmesan a handful at a time until they melt and the sauce turns thick and velvety.

Taste the sauce and adjust seasoning with more salt and pepper if needed. Turn off the heat and let the sauce sit for a couple of minutes to thicken slightly. If the sauce looks too thick, splash in a bit more warm milk until it coats the back of a spoon.

Step 4: Layer the potatoes

Arrange half of the potato slices in the prepared baking dish in slightly overlapping rows. Pour half of the cheese sauce over the potatoes and spread it gently with a spatula so it reaches the corners. Add the remaining potatoes on top in another even layer, then pour the rest of the sauce over everything.

Tap the dish lightly on the counter to help the sauce settle between the slices. Sprinkle a small handful of extra cheddar or Parmesan on top if you want extra cheesy crust. Cover the dish tightly with foil.

Step 5: Bake until tender and bubbly

Place the dish in a preheated 375°F oven. Bake covered for about 35 to 40 minutes until the potatoes start to soften. Remove the foil and continue baking 20 to 25 minutes more until the top turns golden and the sauce bubbles around the edges.

Check doneness by sliding a knife into the center; it should slide in easily without resistance. If the top browns too quickly, tent it loosely with foil and keep baking until the potatoes finish cooking. Once done, remove the dish from the oven and let it rest 10 to 15 minutes before serving.

What to Serve with Tasty Cheesy Scalloped Potatoes Recipe

This Tasty Cheesy Scalloped Potatoes Recipe pairs nicely with simple proteins like roasted chicken, baked salmon, or pan-seared pork chops. You can also serve it alongside grilled sausages or meatloaf for a classic comfort dinner. Add a bright green salad with a tangy vinaigrette or steamed broccoli to cut through the richness. For a cozy meatless meal, serve a big scoop next to roasted vegetables and a crisp apple and walnut salad.

Storage Options

Store leftovers in an airtight container in the fridge for up to 4 days.
Reheat individual portions in the microwave in 30 second bursts, stirring gently, until hot and creamy.
Reheat a larger portion in a covered baking dish at 325°F for 20 to 25 minutes, then uncover for a few minutes if you want the top to crisp again.
Freeze tightly wrapped portions for up to 2 months, then thaw overnight in the fridge before reheating so the texture stays as smooth as possible.
