Key Ingredients & Substitutions
Russet Potatoes: These are perfect for scalloped potatoes due to their starchy nature, which helps create a creamy texture. If you prefer, Yukon gold potatoes are a great substitute for a buttery flavor.
Cheddar Cheese: Sharp cheddar is my favorite because it adds a robust flavor. If you’re looking for something different, try Monterey Jack or Gruyère for a unique twist.
Whole Milk or Half-and-Half: If you’re watching calories, you can use skim milk, but the dish might be less creamy. A non-dairy milk like almond or oat milk can also work, just pick an unsweetened variety.
Onions and Garlic: They enhance the dish’s flavor. If you’re sensitive to onions, consider using shallots for a milder taste or even skipping them altogether. Garlic powder can be used in place of fresh garlic if that’s what you have on hand.
How Do I Avoid a Sticky Mess in My Slow Cooker?
Greasing your slow cooker is essential to prevent your cheesy potatoes from sticking. Here’s how to do it right:
- Use unsalted butter to coat the inside of the pot. This adds flavor while helping food release easily.
- Or, spray with a non-stick cooking spray for a quick and easy alternative.
- Make sure to coat the bottom and sides well for a clean serving!
What’s the Best Way to Layer the Ingredients?
Layering is key to getting the right texture and flavor. Here’s how:
- Start with a layer of potatoes to create a base.
- Follow with onions and pour half the milk mixture over for moisture.
- Don’t forget to sprinkle cheese to add that delicious cheesy goodness. Repeat the layers to maximize flavor!
How to Make Slow Cooker Scalloped Potatoes
Ingredients You’ll Need:
For the Dish:
- 4 large russet potatoes, thinly sliced
- 1 medium onion, thinly sliced
- 3 cloves garlic, minced
- 2 cups shredded sharp cheddar cheese
- 2 cups whole milk or half-and-half
- 1/4 cup unsalted butter, melted
- 1/4 cup all-purpose flour
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon dried thyme (optional)
- 2 tablespoons fresh parsley, chopped (for garnish)
How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and then requires cooking for 6-8 hours on low or 3-4 hours on high. It’s a great option for a busy day since you can set it and forget it until mealtime!
Step-by-Step Instructions:
1. Prepare Your Slow Cooker:
Start by greasing the inside of your slow cooker with some melted butter or a non-stick cooking spray. This will help keep your scalloped potatoes from sticking to the sides, making cleanup easier.
2. Make the Creamy Base:
In a mixing bowl, whisk together the melted butter and flour until you have a smooth paste. Gradually add in the milk (or half-and-half) while whisking continuously to avoid any lumps. Once it’s lump-free, add the minced garlic, salt, pepper, and thyme (if using). Stir everything together until well combined.
3. Layering the Ingredients:
Now it’s time to start layering! First, place half of the sliced potatoes in the bottom of your slow cooker. Next, add half the sliced onion on top of the potatoes. Pour half of the creamy milk mixture over this layer, then sprinkle one cup of the shredded cheddar cheese on top. Repeat this process with the remaining potatoes, onions, and milk mixture—topping it all with the remaining cheese.
4. Slow Cooking:
Cover your slow cooker and set it to cook on low for 6-8 hours or on high for 3-4 hours. The potatoes should be tender and the cheese melted by the time it’s done.
5. Finishing Touches:
About 30 minutes before serving, sprinkle any leftover shredded cheese on top and cover it again to allow the cheese to melt. Once it’s melted and bubbly, it’s almost time to eat!
6. Serving Up:
Garnish your cheesy scalloped potatoes with freshly chopped parsley for a pop of color and flavor. Serve hot as a creamy, cheesy side dish that everyone will love!
Can I Use Different Types of Potatoes?
Absolutely! While russet potatoes are ideal for their creamy texture, you can also use Yukon gold potatoes for a buttery flavor or even red potatoes for a firmer bite. Just make sure to slice them thinly for even cooking!
Can I Prepare This Recipe in Advance?
Yes! You can slice the potatoes and onions a day ahead and store them in the fridge. Just keep them in an airtight container to prevent browning. You can also prepare the milk mixture in advance—just give it a good whisk before using it.
What if I Don’t Have Half-and-Half?
No problem! You can substitute half-and-half with whole milk for a lighter dish or mix equal parts of milk and cream for a richer flavor. Almond or oat milk can be used as a non-dairy alternative; just choose unsweetened varieties for the best results.
How Do I Store Leftover Scalloped Potatoes?
Store any leftovers in an airtight container and refrigerate them for up to 3 days. Reheat in the microwave or on the stovetop over low heat, adding a splash of milk to help bring back the creamy texture!
