Tasty Cheesy Scalloped Potatoes Recipe tastes rich, creamy, ultra cheesy, and a little bit garlicky with tender layers of potatoes that almost melt in your mouth. It works perfectly for holiday dinners, Sunday suppers, potlucks, or any night when you want a cozy side dish in about 1 hour 15 minutes. I grew up in a Midwestern kitchen that measured cheese with the heart, and this recipe follows that same philosophy.

Ingredients You’ll Need

Potatoes

3 pounds Yukon Gold potatoes, peeled and thinly sliced (about 1/8 inch)
- Yukon Golds stay tender and creamy without falling apart.
- You can use Russet potatoes in a pinch, but slice them gently since they break more easily.

Cheese

2 cups shredded sharp cheddar cheese
- Sharp cheddar gives the best flavor and color.
- Use a good block and shred it yourself, since bagged shreds often contain starch that makes the sauce grainy.
1 cup shredded Gruyère or Swiss cheese
- Gruyère adds a nutty, rich flavor.
- Use all cheddar if you prefer, but the mix tastes extra special.
1/4 cup grated Parmesan cheese
- Parmesan adds salty, savory depth and helps the top brown nicely.

Creamy sauce

3 tablespoons unsalted butter
3 tablespoons all-purpose flour
2 cups whole milk (room temperature works best)
1 cup heavy cream
- You can swap half-and-half for the heavy cream if you want a slightly lighter sauce.
2 cloves garlic, minced
1 teaspoon kosher salt
1/2 teaspoon black pepper
1/2 teaspoon onion powder
1/4 teaspoon smoked paprika (optional, for a subtle smoky note)
Pinch of ground nutmeg (optional, but it adds a cozy flavor)

Finishing touches

1 tablespoon fresh thyme leaves or 1 teaspoon dried thyme
2 tablespoons chopped fresh parsley for garnish
Extra salt and pepper to taste

Pantry shortcuts & notes

Use pre-minced garlic from a jar if you feel short on time.
Use pre-shredded cheese only if you must; stir it well so it melts more evenly.
Use boxed chicken broth to replace up to 1/2 cup of the milk if you want a slightly lighter sauce with more savory flavor.

Equipment

9×13 inch baking dish (ceramic or glass)
Medium saucepan
Whisk
Sharp chef’s knife or mandoline slicer
Cutting board
Aluminum foil
Measuring cups and spoons

Tips & Tricks

Slice the potatoes evenly at about 1/8 inch so they cook at the same rate and stay tender.
Keep sliced potatoes in a bowl of cold water if you prep them early, then dry them well before layering so the sauce stays thick.
Warm the milk and cream slightly or use room temperature dairy so the sauce thickens smoothly.
Whisk the flour into the melted butter until it smells toasty to avoid a raw flour taste.
Add cheese off the heat and stir until it melts so the sauce stays silky and does not separate.
Season each layer of potatoes lightly with salt and pepper so the whole dish tastes well seasoned.
Cover the dish for the first part of baking so the potatoes soften, then uncover to brown the top.
Let the scalloped potatoes rest 10 to 15 minutes after baking so the sauce thickens and slices hold together.
Use a mandoline slicer carefully if you want super thin, even slices and faster prep.
Grease the baking dish well so the cheesy edges release more easily and you get those tasty browned bits.

How to Make Tasty Cheesy Scalloped Potatoes Recipe

Prep the potatoes and oven

Preheat your oven to 375°F and grease a 9×13 inch baking dish with butter or cooking spray.
Peel the potatoes, then slice them into 1/8 inch rounds with a sharp knife or mandoline.
Place the slices in a large bowl of cold water while you work to prevent browning.
When you finish slicing, drain the potatoes and pat them very dry with clean kitchen towels or paper towels.

Make the creamy cheese sauce

Set a medium saucepan over medium heat and add the butter.
When the butter melts and starts to foam, add the flour and whisk constantly for 1 to 2 minutes until the mixture turns slightly golden and smells nutty.
Slowly pour in the milk and cream while you whisk, breaking up any lumps.
Keep whisking until the mixture thickens and coats the back of a spoon, about 4 to 6 minutes.
Stir in the garlic, salt, pepper, onion powder, smoked paprika, and nutmeg.
Turn the heat to low and add the cheddar, Gruyère, and Parmesan in small handfuls.
Whisk after each addition until the cheese melts and the sauce turns smooth and glossy.
Taste the sauce and adjust the seasoning with a little more salt or pepper if you like.

Layer the potatoes and sauce

Arrange half of the potato slices in an even layer in the prepared baking dish.
Season the potatoes lightly with a pinch of salt, pepper, and half of the thyme.
Pour about half of the cheese sauce over the potatoes and spread it gently with a spatula so it covers the slices.
Add the remaining potatoes on top in another even layer.
Season again with a light sprinkle of salt, pepper, and the rest of the thyme.
Pour the remaining cheese sauce over the top and spread it so it seeps into the layers.
Sprinkle a small handful of extra cheddar or Parmesan on top if you want an extra cheesy crust.
Cover the baking dish tightly with foil.

Bake to tender, cheesy perfection

Place the covered dish on the middle rack of the oven and bake for 35 to 40 minutes.
Remove the foil and check the potatoes by piercing the center with a knife; the knife should slide in with just a little resistance.
Continue baking uncovered for another 20 to 25 minutes until the top turns golden and bubbly and the potatoes feel very tender.
If the top browns too quickly, tent the dish loosely with foil again while the potatoes finish softening.

Rest, garnish, and serve

Take the dish out of the oven and set it on a cooling rack.
Let the scalloped potatoes rest for 10 to 15 minutes so the sauce thickens and the layers set.
Sprinkle chopped parsley over the top for a fresh pop of color and flavor.
Slice into squares or scoop with a large spoon and serve warm.

What to Serve with Tasty Cheesy Scalloped Potatoes Recipe

This Tasty Cheesy Scalloped Potatoes Recipe pairs beautifully with roasted chicken, baked ham, grilled pork chops, or a simple pan-seared steak alternative like turkey cutlets.

Kids usually love this dish, so it works well with simple proteins like baked chicken tenders or turkey meatloaf.

Storage Options

Cool leftovers to room temperature, then cover the baking dish tightly or transfer portions to airtight containers and store in the fridge for up to 4 days.

Reheat in the oven at 350°F, covered, until hot and bubbly, about 20 minutes from the fridge or 30 to 35 minutes from frozen.
Reheat single servings in the microwave in short bursts, stirring gently between bursts, and add a spoonful of milk or cream if the sauce looks too thick.
