Ingredients and Substitutions
Gathering the right ingredients is your first step to success. Let’s break down what you need and explore some flexible swaps.
Base Components
Potatoes form the foundation of this dish. Russet potatoes are ideal because they hold their shape well and absorb the sauce beautifully. You can also use Yukon Gold potatoes for a slightly creamier texture. A fresh onion and garlic build the essential aromatic base, providing a savory depth that balances the richness of the cheese and cream.
For the Creamy Sauce
The sauce starts with a simple roux of butter and flour, which thickens the mixture perfectly. Vegetable broth and heavy cream create the luxurious liquid base. For a lighter version, you could use half-and-half instead of heavy cream, though the sauce will be slightly less rich. Sour cream adds a delightful tanginess that cuts through the fat.
The Three Cheese Blend
The star of the show is, of course, the cheese blend. Using a mix of Colby Jack, cheddar, and Parmesan gives you the perfect balance of melt, sharpness, and salty flavor. You can easily customize this blend based on what you have on hand. Monterey Jack, Gouda, or even a smoked cheese would be delicious additions or substitutions.

How to Make Three Cheese Scalloped Potatoes
Follow these simple steps for a foolproof, delicious result. The process is mostly hands-off, letting the oven do the heavy lifting.
Step 1: Prep Your Potatoes and Pan
Begin by preheating your oven to 400 degrees Fahrenheit. Take a 9×13-inch casserole dish or baking pan. Peel your Russet potatoes and slice them uniformly to about 1/8-inch thickness. A mandoline slicer is highly recommended for achieving perfectly even slices quickly. Arrange the potato slices upright in the pan, standing them on their edges along one of the long sides. Continue creating columns of potato slices until you fill the pan. This unique arrangement allows the sauce to seep between every layer, ensuring maximum flavor in every bite.
Step 2: Build the Flavor Base
In a medium saucepan over medium heat, melt the unsalted butter. Add the diced onion and minced garlic. Cook them for about 5 minutes, stirring frequently, until they become soft and fragrant. This step is crucial for developing the foundational flavors of your dish.
Step 3: Make the Roux and Sauce
Sprinkle the all-purpose flour over the onion and garlic mixture. Cook this roux for about one minute, whisking nearly constantly. You want the flour to lose its raw taste and turn a light golden color. This process is key for properly thickening your sauce later. Next, whisk in the salt, your chosen seasoning blend, black pepper, vegetable broth, and heavy cream. Bring the mixture to a gentle simmer, stirring constantly. Let it cook for about 3 minutes until it thickens noticeably. The sauce should coat the back of a spoon.
Step 4: Incorporate the Cheese
Turn off the heat under your saucepan. Now, stir in one cup of the shredded Colby Jack cheese, one cup of the shredded cheddar cheese, and a half cup of the shredded Parmesan cheese. Stir until the cheeses are completely melted and the sauce is smooth and velvety. Set this cheesy sauce aside for a moment.
Step 5: Assemble the Casserole
Take your prepared pan of upright potato slices. Using a spoon or offset spatula, gently spread the sour cream evenly over the tops of the potato columns. Then, slowly and carefully pour the warm cheese sauce over the potatoes, making sure it drips down into all the crevices. Finally, evenly sprinkle the remaining half-cup portions of Colby Jack, cheddar, and Parmesan cheeses over the top.
Step 6: Bake to Perfection
Cover the baking dish tightly with aluminum foil. Place it in your preheated oven and bake for 1 hour. After this time, remove the dish from the oven and carefully lift the foil to check for doneness. The potatoes should be fork-tender. If they still feel firm, re-cover the dish with the foil and return it to the oven for an additional 10 to 15 minutes.
Once the potatoes are fully cooked, remove and discard the foil. Return the uncovered dish to the oven and bake for another 30 minutes, or until the cheese on top is bubbly and beautifully golden brown. Keep a close eye during these final minutes to prevent over-browning. Let the casserole rest for about 5 minutes before serving to allow it to set slightly.
Pro Tips for Success
A few simple tricks will guarantee your scalloped potatoes turn out perfectly every single time.
- Slice Evenly: Consistent potato slices are non-negotiable. They ensure everything cooks at the same rate. A mandoline is the best tool for this job, but a sharp knife and careful attention work too.
- Don’t Rush the Roux: Take the full minute to cook your flour and butter mixture. This step cooks out the raw flour taste and activates its thickening power, preventing a pasty sauce.
- Use Freshly Shredded Cheese: Pre-shredded cheeses often contain anti-caking agents that can make your sauce grainy. For the smoothest, creamiest results, buy blocks of cheese and shred them yourself just before using.
- Let it Rest: Allowing the casserole to sit for 5-10 minutes after baking helps the sauce thicken slightly and makes it much easier to serve neat portions.
Flavor Variations
This recipe is wonderfully adaptable. Feel free to get creative and make it your own with these easy twists.
- Herb-Infused: Add a tablespoon of fresh chopped thyme or rosemary to the onion and garlic as they cook for an aromatic herbal note.
- Smoky Twist: Substitute one cup of the cheddar cheese with a smoked gouda or smoked cheddar for a deep, woodsy flavor.
- Extra Veggie: Add a layer of thinly sliced mushrooms or spinach between the potato columns before adding the sauce for added nutrition and color.
- Spicy Kick: Mix a teaspoon of smoked paprika or a pinch of cayenne pepper into the seasoning blend for a gentle heat.
Serving Suggestions
These rich and cheesy potatoes are a spectacular side dish that complements many mains. They are a classic partner for a holiday ham or a perfectly roasted turkey. For a simpler dinner, serve them alongside juicy baked chicken breasts or crispy roasted chicken thighs.
They also pair beautifully with a green vegetable to balance the meal; try steamed green beans, roasted broccoli, or a simple garden salad.

Storage and Freezing Instructions
Leftovers store beautifully, making this a great make-ahead option. Allow the casserole to cool completely after baking. Then, cover the baking dish tightly with plastic wrap or aluminum foil, or transfer portions to an airtight container.
Store it in the refrigerator for up to 4 days. To reheat, place individual portions in the microwave until warmed through. For larger amounts, cover the dish with foil and reheat in a 350-degree Fahrenheit oven for 20-30 minutes.
You can also freeze this dish. After cooling, wrap the entire casserole or portions tightly in both plastic wrap and foil. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating in the oven as directed above.

FAQs About Three Cheese Scalloped Potatoes
Here are answers to the most common questions about making this beloved dish.
Can I make this dish ahead of time?
Absolutely. You can assemble the entire casserole up to a day in advance. Cover it tightly and refrigerate it. When you’re ready to bake, you may need to add 10-15 minutes to the covered baking time since it will be going into the oven cold.
Why are my scalloped potatoes watery?
A watery result usually comes from not cooking the roux long enough or using potatoes with a high water content, like red potatoes. Russets are best. Also, ensure your sauce has thickened on the stovetop before pouring it over the potatoes.
What’s the difference between scalloped and au gratin potatoes?
Traditionally, scalloped potatoes are baked in a cream sauce without cheese, while au gratin potatoes include cheese. However, many modern recipes, like this one, blend the concepts, creating a cheesy, creamy casserole that enjoys the best of both worlds.
Can I use a different type of potato?
Yes, Yukon Gold potatoes are an excellent alternative. They are waxier and will yield a slightly creamier, denser texture. Russet potatoes give a more classic, fluffy result.
How do I know when the potatoes are fully cooked?
The best test is to insert a thin knife or a fork into the center of the casserole. It should slide into the potato slices with no resistance. If you feel any hardness, they need more baking time.

In conclusion, this Three Cheese Scalloped Potatoes recipe is a guaranteed winner for any occasion. Its layers of tender potato, rich sauce, and bubbly cheese create a side dish that often steals the spotlight.

- 2 tablespoons unsalted butter (28 g)
- 2 tablespoons all-purpose flour (15 g)
- 2 teaspoons Kosher salt (or to taste) (12 g)
- 2 teaspoons seasoning blend such as Mrs. Dash (Trader Joe’s 21 Salute, or poultry seasoning*)

- 1 cup vegetable broth (240 ml)
- 1 cup heavy cream (240 ml)
- 1 cup sour cream (240 g)
- 1.5 cups shredded Colby Jack cheese (divided) (170 g)

- 1 cup shredded Parmesan cheese (divided) (100 g)
Instructions
- Preheat oven to 400F and to a 9×13-inch casserole dish or baking pan, arrange the potatoes upright in the pan along one of the long edges. Repeat with the remaining potatoes until you have three columns of potato slices; set aside.
- To a saucepan, add and melt the butter, add the onion and garlic, and cook for 5 minutes; stir frequently.
- Add flour, and cook for another minute, whisking nearly constantly, or until the flour is lightly golden browned.
- Add the salt, seasoning blend, pepper, broth, cream, and stir until somewhat thickened, about 3 minutes.
- Turn off the heat and stir in 1 cup each of the Colby Jack and cheddar cheeses and 1/2 cup of the Parmesan; set aside momentarily.
- Spread the sour cream over potatoes and pour the cheesy mixture evenly over potatoes.
- Evenly sprinkle the remaining one-half cup of each of the three cheeses over potatoes.
- Cover potatoes with foil and bake for 1 hour, remove from the oven, and check for doneness. The potatoes should be fork tender.
- If they’re not cooked through yet, recover with the foil and bake for an additional 10 to 15 minutes, or as long as necessary so they cook through.
- After the potatoes have cooked through completely, remove and discard the foil, and allow the potatoes to bake uncovered for an additional 30 minutes, or as desired to brown the cheeses.
- Allow potatoes to cool momentarily before serving, about 5 minutes.
Notes
- Tip: Using a mandoline slicer ensures perfectly even potato slices for the best texture and even cooking.
- Tip: For the smoothest sauce, shred your own cheese from blocks rather than using pre-shredded cheese.
- Note: Keep a close eye on the potatoes during the final uncovered baking time to prevent the cheese from over-browning.
