- 8×8-inch casserole dish (for baking)
- Medium-size saucepan (for making cheese sauce)
- Whisk (for stirring sauce)
- Knife and cutting board (for slicing potatoes and onions)
- Measuring cups and spoons
- Aluminum foil (for covering the dish)
These basic kitchen tools will help you layer the potatoes and prepare the cheese sauce with ease.
Step-by-Step Guide to Making Cheesy Scalloped Potatoes
Step 1: Preheat the Oven
Preheat your oven to 400°F. Lightly spray an 8×8-inch casserole dish with nonstick cooking spray to prevent sticking.
Step 2: Arrange the Potatoes and Onions
Peel the russet potatoes and slice them into ¼-inch thick slices. Slice the yellow onion into rings. Layer the potatoes and onions in the prepared casserole dish, alternating between the two to create an even layer.
Step 3: Make the Cheese Sauce
In a medium-size saucepan, melt the butter over medium heat. Once melted, whisk in the flour and kosher salt, stirring constantly for about 1 minute until the mixture is smooth and bubbly.
Slowly pour in the room-temperature milk, whisking continuously to prevent lumps. Cook the mixture, whisking frequently, until it thickens and begins to bubble.
Once the sauce has thickened, stir in the shredded cheddar cheese all at once. Continue stirring for 30-60 seconds until the cheese is fully melted and the sauce is smooth and creamy.
Step 4: Pour the Cheese Sauce Over the Potatoes
Pour the prepared cheese sauce evenly over the potatoes and onions in the casserole dish. Gently shake the dish to allow the sauce to settle between the potato layers.
Step 5: Bake the Potatoes
Cover the casserole dish with aluminum foil and bake in the preheated oven for 85-90 minutes, or until the potatoes are tender when pierced with a fork.
Step 6: Broil for a Crisp Topping
For a crispy golden topping, change the oven setting to broil after the potatoes have finished baking. Broil the potatoes uncovered for 2-3 minutes until the top is golden brown and crispy.
Step 7: Season and Serve
Once the potatoes are done, remove the dish from the oven and let it cool for a few minutes. Season with salt and pepper to taste before serving. Enjoy this creamy, cheesy side dish with your favorite main course.

Common Mistakes to Avoid
- Not slicing potatoes evenly: Make sure to slice the potatoes into uniform ¼-inch slices so they cook evenly and become tender at the same time.
- Cold milk: Use room-temperature milk to ensure the cheese sauce thickens properly. Cold milk can cause lumps in the sauce.
- Skipping the foil: Covering the dish with foil during baking helps the potatoes cook evenly and prevents the cheese sauce from drying out.
Tips & Tricks for the Best Cheesy Scalloped Potatoes
- Use Sharp Cheddar: For a more intense flavor, swap mild cheddar for sharp cheddar cheese. You can also mix in other cheeses like Gruyere or Parmesan for added depth.
- Add Fresh Herbs: For a fresh twist, sprinkle chopped parsley or thyme over the finished dish.
- Make It Ahead: You can assemble the dish ahead of time and store it in the refrigerator. When ready to bake, bring it to room temperature and follow the baking instructions.
