Why Make This Cheesy Scalloped Potatoes for a Crowd
Making a side dish for a large group can be stressful, but this recipe makes it easy. It is very budget-friendly because potatoes are inexpensive even when bought in bulk. You can prepare most of the dish ahead of time, which saves you precious minutes when your guests arrive. Unlike individual servings, a big tray of scalloped potatoes allows people to scoop exactly how much they want. The combination of cheddar and parmesan creates a flavor profile that appeals to both kids and adults. Plus, it is incredibly filling, making it a reliable centerpiece for any large gathering.
How to Make Cheesy Scalloped Potatoes for a Crowd
The process starts with choosing the right potatoes and slicing them evenly. Uniform slices ensure that every potato piece cooks at the exact same rate, preventing some from being mushy while others are crunchy. You will create a homemade cheese sauce, also known as a mornay sauce, by starting with a simple butter and flour roux. This sauce is what gives the dish its signature creaminess. By layering the potatoes and pouring the sauce over them in stages, you ensure that every single slice is coated in cheesy goodness. The slow baking process allows the starches to release, thickening the sauce into a rich gravy that clings to the vegetables.
Ingredients:
- 10 pounds Yukon Gold or Russet potatoes, peeled and sliced into 1/8-inch rounds
- 1 cup unsalted butter
- 1 cup all-purpose flour
- 6 cups whole milk
- 2 cups heavy cream
- 6 cloves garlic, minced
- 1 large yellow onion, finely diced
- 2 tablespoons salt
- 1 teaspoon black pepper
- 1 teaspoon dried thyme
- 6 cups shredded sharp cheddar cheese
- 1.5 cups grated Parmesan cheese
- Fresh parsley, chopped (for garnish)
Directions:
- Preheat your oven to 375°F (190°C). Lightly grease two large 9×13-inch baking dishes or one extra-large catering pan with butter.
- In a large pot or Dutch oven, melt the butter over medium heat. Add the diced onion and cook for about 5 minutes until soft and translucent. Stir in the minced garlic and cook for another minute until fragrant.
- Whisk in the flour to create a paste. Cook the flour mixture for 2 minutes, stirring constantly to remove the raw flour taste.
- Slowly pour in the milk and heavy cream while whisking vigorously to avoid lumps. Continue cooking and stirring until the sauce thickens enough to coat the back of a spoon.
- Remove the pot from the heat. Stir in the salt, black pepper, dried thyme, and 4 cups of the shredded cheddar cheese. Stir until the cheese is completely melted and the sauce is smooth.
- Place a layer of sliced potatoes in the bottom of your prepared baking dishes. Pour about one-quarter of the cheese sauce over the layer. Repeat the layers of potatoes and sauce until all potatoes are used, ending with a layer of sauce on top.
- Cover the dishes tightly with aluminum foil. Bake in the preheated oven for 45 to 50 minutes.
- Carefully remove the foil. Sprinkle the remaining 2 cups of cheddar cheese and the Parmesan cheese evenly over the top.
- Bake uncovered for another 25 to 30 minutes. The potatoes should be fork-tender, and the top should be golden brown and bubbly.
- Remove from the oven and let the dish rest for at least 15 minutes before serving. This allows the sauce to set and makes serving much easier. Garnish with fresh parsley before bringing it to the table.

How to Serve Cheesy Scalloped Potatoes for a Crowd
These potatoes are versatile and pair beautifully with many main courses. Serve them alongside a juicy roast beef or grilled lamb chops for a classic hearty meal. They also go well with roasted chicken or a pan-seared fish. If you are hosting a brunch, these potatoes are a fantastic partner for omelets or savory beef sausages. To balance the richness of the cheese and cream, serve a crisp green salad with a sharp lemon vinaigrette on the side. Steamed green beans or roasted broccoli also provide a nice color contrast and a healthy touch to the plate.
How to Store Cheesy Scalloped Potatoes for a Crowd
If you have leftovers, you are in luck because they taste even better the next day! Store the potatoes in an airtight container in the refrigerator for up to 4 days. When you want to reheat them, the oven is your best friend. Place the potatoes in an oven-safe dish, cover with foil, and bake at 350°F until heated through. This helps maintain the creamy texture. If you are in a rush, the microwave works too, though the edges might lose their crispness. You can also freeze these potatoes for up to 2 months. Thaw them in the fridge overnight before reheating in the oven.
Expert Tips for Perfect Cheesy Scalloped Potatoes for a Crowd
- Use a Mandoline: To get perfectly even slices, use a mandoline slicer. This ensures the potatoes cook at the same speed.
- Don’t Rinse: Do not rinse the potato slices after cutting. The natural starch on the surface helps thicken the sauce.
- Let it Rest: Be patient! Letting the dish sit for 15 minutes after baking is crucial. If you cut into it immediately, the sauce will be too runny.
- Cheese Choice: Use high-quality block cheese and shred it yourself. Pre-shredded cheese is coated in potato starch which can make your sauce grainy.
- Potato Type: Yukon Gold potatoes are excellent because they hold their shape well and have a naturally buttery flavor.
Delicious Variations
- Smoky Beef: Add chopped cooked beef strips or halal beef bacon bits between the layers for a deep, smoky flavor.
- Spicy Kick: Mix in some diced jalapeños or a teaspoon of red chili flakes into the cheese sauce for a bit of heat.
- Herb Garden: Use fresh rosemary and sage instead of dried thyme for an earthy, aromatic twist.
- Onion Crunch: Top the dish with crispy fried onions during the last 10 minutes of baking for extra texture.
- Vegetable Boost: Add a layer of thinly sliced leeks or sautéed spinach between the potato layers for extra nutrients.
Frequently Asked Questions
1. Can I make this dish the night before?
Yes! You can assemble the entire dish, cover it, and keep it in the fridge overnight. Just add about 10-15 minutes to the baking time since you are starting from a cold temperature.
2. Why did my sauce curdle?
Curdling usually happens if the heat is too high or if you use low-fat milk. Stick to whole milk and heavy cream, and do not let the sauce reach a hard boil.
3. Do I have to peel the potatoes?
While peeling gives a more refined look, you can leave the skins on for a rustic style and extra fiber. Just make sure to scrub them very well.
4. Can I use a different type of cheese?
Absolutely. Gruyere, Monterey Jack, or even a smoked Gouda work wonderfully in this recipe.
5. How do I know when the potatoes are done?
Poke the center of the dish with a sharp knife or fork. It should slide through the potato layers with zero resistance.
