Scalloped Potatoes Recipe

Ingredients

4 large potatoes, thinly sliced (Yukon Gold or any variety)
¼ cup unsalted butter
1 ½ cups finely chopped onion
2 tablespoons plain flour (for gluten-free, use cornstarch or a gluten-free flour blend)
2 cups warm milk (whole milk or any plant-based alternative like almond or oat milk for vegan)
2 garlic cloves, minced
2 ¼ cups shredded cheese (cheddar, mozzarella, Monterey Jack mix; for vegetarian, use rennet-free cheese; for vegan, use plant-based cheese)
⅓ cup chopped fresh chives
Cooking spray or a little oil for greasing

Instructions

Preheat your oven to 375°F (190°C). Lightly grease a deep 9×9-inch baking dish with cooking spray or a little oil.
In a medium saucepan, melt the butter over medium heat. Add the chopped onions and cook until they turn soft and translucent.
Sprinkle in the flour, stirring well so it blends with the butter and onions. Cook for a minute to remove the raw flour taste.
Slowly pour in the warm milk while stirring continuously to avoid lumps. Add the minced garlic and keep stirring until the sauce thickens and starts to bubble.
Remove from heat and mix in 2 cups of the shredded cheese. Stir until the cheese melts and blends into the sauce. Set aside.
Arrange a single layer of potato slices in the greased baking dish. Sprinkle some chopped chives on top. Repeat the layers of potatoes and chives until all the potatoes are used.
Pour the cheese sauce evenly over the potatoes, letting it seep into the layers. Gently shake the dish to help the sauce spread.
Sprinkle the remaining ¼ cup of cheese on top along with a few more chives for extra flavor.
Place the dish on a baking sheet to catch any spills. Bake for about 60 minutes or until the top is golden brown and bubbling. The potatoes should be soft when tested with a fork.
Let it rest for a few minutes before serving. Enjoy warm!

What Are Scalloped Potatoes?

Scalloped potatoes are a baked dish made with thinly sliced potatoes layered in a creamy sauce, then cooked until soft and golden brown.

The sauce is usually made with milk or cream, butter, flour, and seasonings, creating a rich and velvety texture.

Unlike au gratin potatoes, which include a layer of breadcrumbs or extra cheese, scalloped potatoes focus on the smooth, creamy goodness of the sauce. They make a perfect side dish for meats, seafood, or even a simple salad.

What Makes This Scalloped Potatoes Recipe Special?

This recipe stands out because it keeps things simple but incredibly delicious. Every bite is rich, cheesy, and packed with flavor. Here’s what makes it different:

Garlic-infused cheese sauce: The combination of garlic and melted cheese takes the creamy sauce to the next level.
Perfectly layered potatoes: Thin slices ensure even cooking and a soft, melt-in-your-mouth texture.
Golden, bubbly top: The final bake creates a crispy, cheesy crust that adds the perfect contrast to the tender potatoes.
Easy to customize: You can make it vegetarian, gluten-free, or even add proteins like chicken or beef for a heartier dish.
A crowd-pleaser: Whether for family dinners, holiday feasts, or special occasions, this dish always gets compliments.

What Type Of Potatoes Work Best For Scalloped Potatoes?

The right potatoes make a big difference in texture and taste. Here are the best choices:

Yukon Gold: These are the top choice because they have a creamy texture and hold their shape well.
Russet Potatoes: They are softer and break down more, giving a slightly mushier but still delicious result.
Red Potatoes: They hold their shape better but don’t become as creamy as Yukon Golds.

What’s The Best Cheese For Scalloped Potatoes?

Cheese adds flavor and richness, but not all cheeses melt well. The best options include:

Cheddar: Sharp or mild, it melts beautifully and gives a bold flavor.
Mozzarella: Creates a gooey texture and pairs well with other cheeses.
Monterey Jack: Has a mild, buttery taste and melts smoothly.
Parmesan: Adds a slightly salty, nutty flavor when sprinkled on top.

For the best results, use a mix of cheddar, mozzarella, and Monterey Jack for a creamy, flavorful dish with a perfect melt.

Can I Prepare Scalloped Potatoes Ahead Of Time?

Yes, scalloped potatoes can be made in advance, which makes them a great choice for busy days or special gatherings. Here’s how:

Prepare but don’t bake: Assemble the dish, cover it tightly, and refrigerate for up to 24 hours before baking.
Partially bake: Cook for about 40 minutes, let it cool, then refrigerate. When ready to serve, bake again until fully heated and golden.
Freeze for later: Cool completely, wrap well, and freeze for up to 3 months. Reheat in the oven at 350°F (175°C) until warm.

Why Did My Sauce Turn Out Grainy Or Lumpy?

A smooth and creamy sauce is key to perfect scalloped potatoes, but sometimes it can turn out grainy or lumpy. This usually happens due to a few common mistakes:

Overheating the milk: High heat can cause the milk to curdle, leading to a grainy texture. Always heat it gently and avoid boiling.
Not stirring enough: If the flour isn’t mixed in properly, it can create lumps. Stir continuously to keep the sauce smooth.
Using pre-shredded cheese: Store-bought shredded cheese has anti-caking agents that prevent melting properly. Use freshly grated cheese for the best results.
Adding cheese too fast or too hot: If you add cheese to a sauce that’s too hot, it can separate and become grainy. Always remove the pan from heat before stirring in the cheese.

How Do I Prevent My Potatoes From Turning Brown Before Baking?

Sliced potatoes can turn brown quickly when exposed to air, but there are simple ways to stop this:

Soak in cold water: Place the slices in a bowl of cold water if you’re not layering them right away. This slows down oxidation.
Use lemon juice or vinegar: A splash of lemon juice or white vinegar in the water helps prevent browning without changing the taste.
Work quickly: The faster you assemble the dish, the less time the potatoes have to darken.

Can I Freeze Scalloped Potatoes?

Yes, scalloped potatoes can be frozen, but they need proper handling to keep their texture and flavor. Here’s how:

Freeze after baking: Fully cook the dish, let it cool completely, then wrap it tightly in plastic wrap and foil. Store for up to 3 months.
Avoid freezing raw potatoes: Uncooked potatoes become grainy and watery when frozen.
Reheat properly: Thaw overnight in the fridge and bake at 350°F (175°C) until heated through. Cover with foil first, then remove for the last 10 minutes to crisp up the top.

How Do I Get A Crispy, Golden Top?

A bubbly, golden crust makes scalloped potatoes extra delicious. To achieve that perfect crispy top:

Use a mix of cheeses: Harder cheeses like Parmesan or cheddar brown better than soft ones. Sprinkle some on top before baking.
Bake uncovered at the end: If you cover the dish while baking, remove the foil for the last 15-20 minutes to let the top crisp up.
Broil for extra crunch: If the top isn’t golden enough, place the dish under the broiler for 2-3 minutes. Watch closely to avoid burning.
Add breadcrumbs: A light sprinkle of breadcrumbs mixed with melted butter can create an extra crunchy layer.

How Do I Store And Reheat Leftovers?

Scalloped potatoes taste just as good the next day if stored and reheated properly. Here’s how to keep them fresh and delicious:

Refrigerate properly: Let the dish cool completely, then store in an airtight container or cover the baking dish tightly with plastic wrap. It will stay fresh for 3-4 days in the fridge.
Reheat in the oven for best texture: Preheat the oven to 350°F (175°C), cover the dish with foil, and bake for 20-25 minutes until warm. Remove the foil for the last few minutes to crisp up the top.
Use the microwave for convenience: Place a portion on a microwave-safe plate, cover with a damp paper towel, and heat in 30-second intervals until warmed through.
Avoid freezing if possible: While you can freeze scalloped potatoes, the texture may change, making them grainy or watery after thawing. If freezing, wrap tightly and reheat in the oven for the best results.
