Brandi’s Key Ingredients

The Difference Between Scalloped and Au Gratin Potatoes

Scalloped potatoes and potatoes au gratin are both delicious potato dishes, but they have some key differences in their preparation and presentation:

• Ingredients: Both dishes use sliced potatoes as the main ingredient, but the variation lies in the additional ingredients and seasonings. Scalloped potatoes typically consist of potatoes, butter, milk or cream, and sometimes onions or cheese. Potatoes au gratin usually include potatoes, cheese, cream, and sometimes garlic or herbs.
• Cheese: Both dishes can contain cheese, the use of cheese is usually found in potatoes au gratin. Cheese is a defining feature of potatoes au gratin and is typically layered between the potato slices and on top, resulting in a cheesy and creamy texture. Scalloped potatoes may or may not have cheese, and if it is used, it is usually sprinkled on top rather than layered throughout.
• Texture: Scalloped potatoes are generally creamier and softer in texture. The potatoes are typically baked in a creamy sauce, resulting in a tender and moist dish. Potatoes au gratin, on the other hand, have a more gratin-like texture. The cheese forms a golden crust on top, giving it a slightly crispy and cheesy exterior, while the interior remains creamy.

What Type of Potatoes to Use

It is best to use potatoes that hold their shape well and don’t become too mushy during the slow cooking process. Regardless of the potato type you choose, make sure to wash and scrub them thoroughly before slicing or cubing. This helps retain the nutrients and flavor of the potatoes. Also, try to keep the potato pieces uniform in size to ensure even cooking.

Here are a few types of potatoes that work well:

• Russet Potatoes: They have a high starch content, which helps them hold their shape while becoming tender and creamy. Russets also absorb flavors well, making them great for soaking up the cheesy sauce.
• Yukon Gold Potatoes: They have a slightly waxy texture and a rich, buttery flavor. Yukon Golds hold their shape nicely when cooked and provide a creamy and velvety texture to the dish.
• Red Potatoes: They have smooth, thin skin and a firm, waxy texture. Red potatoes hold up well during baking and offer a slightly sweet and creamy taste.

How to Slice the Potatoes

Wash the potatoes thoroughly under cold water to remove any dirt or debris. You can choose to peel the potatoes or leave the skin on for added texture and nutrients. If you decide to peel them, use a vegetable peeler to remove the skin.

Use a sharp knife or a mandoline slicer (I love to use this one from Amazon) to slice the potatoes into even, thin slices. Aim for a thickness of around 1/8 to 1/4 inch for evenly cooked and tender potatoes. If using a knife, take care to make consistent slices to ensure even cooking.

After slicing, pat the potato slices dry. This will remove excess moisture, allowing the potatoes to cook and brown more effectively.

What Type of Cheese to Use

• Cheddar Cheese: Sharp cheddar cheese is a classic choice for cheesy potatoes. Its sharp and tangy flavor pairs well with the creamy potatoes. You can use either pre-shredded cheddar cheese or shred it yourself for better melting.
• Parmesan Cheese: It has a rich, sharp, and nutty flavor that adds depth and complexity to the dish. Its distinct taste stands out and enhances the overall savory profile of the potatoes.
• Gruyere Cheese: Gruyere cheese is a Swiss cheese with a nutty and slightly sweet flavor. It melts beautifully and adds a rich and complex taste to the potatoes. Gruyere is often used in more elevated versions of cheesy potatoes.
• Colby Jack Cheese: It’s a semi-soft cheese made from a blend of Colby and Monterey Jack cheeses. It has a mild and creamy flavor. It melts well and adds a nice creaminess to the dish.
• Monterey Jack Cheese: A semi-soft, mild cheese with a buttery flavor. It has a smooth and creamy texture when melted.
• Fontina Cheese: It is an Italian cheese with a mild and nutty flavor. It melts smoothly and evenly, making it ideal for cheesy potato dishes.

Buy Blocks of Cheese and Grate Instead of Bags of Pre-Shredded Cheese

I always buy blocks of cheese and grate them myself. I do not recommend using pre-shredded, bagged cheese. I use the shred blade on my food processor to save time with this process. Here’s why I don’t use pre-shredded:

• Superior melting: Pre-shredded cheese is coated with anti-caking agents, such as potato starch or cellulose, to prevent clumping and make it last longer in the store. These coatings interfere with the cheese’s ability to melt smoothly and affect the texture of your dishes. When you grate your cheese fresh, it doesn’t have these additives and preservatives, resulting in a more velvety and evenly melted cheese.
• Better flavor: Pre-shredded cheese is exposed to more surface area, which can cause it to dry out faster and lose some of its flavor. By grating your cheese just before using it, you retain the natural moisture and full flavor of the cheese.

How to Make Slow Cooker Crockpot Cheesy Potatoes

Detailed measurements and full instructions can be found in the recipe card at the bottom of this post.

1. Combine milk, broth, heavy cream, softened cream cheese, garlic, onion powder, salt, and pepper in a cup or bowl to create a sauce.
2. Add 1/3rd of the sliced potatoes to the bottom of the slow cooker.
3. Pour half of the sauce over the potatoes. Layer in 1/3rd of the grated cheese.
4. Add an additional 1/3rd of the potatoes to create another layer, add the remaining sauce, and 1/3rd of the grated cheese.
5. Add a final layer of potatoes and the remaining grated cheese.
6. Place the lid on the pot and slow cook.

Cook Time/How Long to Cook

You will need to cook the potatoes for 3-4 hours on High or 4-6 hours on Low. Every slow cooker cooks at varying speeds, even when they are the same brand. If it’s your first time making the dish be sure to keep a watchful eye.

I don’t like to use the “Keep Warm” setting when making Crockpot potatoes. If you keep heat on the potatoes, when cooked they will soften up even more and will likely fall apart. Keep this is mind while cooking.

Once the potatoes are fully cooked and soft, allow the dish to cool and stand for 20-30 minutes before serving. This will thicken up the cheesy cream sauce. Don’t skip this step. The sauce may look thin and runny at first, but it will thicken up upon standing.

Additional Toppings and Add-ins

Can You Make it Ahead/How to Store Leftovers

You can store leftovers tightly covered and sealed for 3-4 days.

How to Reheat

• Air Fryer or Oven: You can reheat the dish in the oven or air fryer at 350 degrees until warm.
• Microwave: Use high power in 1-minute intervals, stirring or rearranging the potatoes between each interval. This helps ensure even heating.

Can You Freeze it

The potatoes can be frozen tightly covered and sealed for up to 3 months. After this time, the quality and flavor may start to deteriorate. Defrost overnight in the fridge.

Freezing and thawing can affect the texture of the potatoes slightly. Because the dish has dairy there will likely be some separation when you reheat. The potatoes may become softer or lose some of their original firmness. However, the taste and flavors should remain relatively intact.
