Preparation Phase

Essential Tools and Equipment

• Mandoline slicer or sharp knife – Ensures even 1/8-inch potato slices for uniform cooking
• Large saucepan – Perfect for preparing a smooth, thickened cheese sauce
• Whisk – Helps create a lump-free, creamy sauce
• 9″x13″ casserole dish – Standard size for even layering and baking
• Aluminum foil – Keeps moisture in during the first half of baking to prevent the top from burning

Importance of Each Tool

Using the right tools is key to achieving the best texture and flavor. Uniform slices help the potatoes cook evenly, a whisk prevents clumps in the roux, and a casserole dish allows for perfect layering. Each item plays a role in ensuring that your cheesy garlic scalloped potatoes turn out creamy, cohesive, and fully cooked through.

Preparation Tips

• Slice potatoes as evenly as possible (1/8 inch is ideal)
• Do not rinse the sliced potatoes—natural starch helps thicken the dish
• Use freshly shredded cheese for optimal melt and flavor
• Let the dish sit for 10 minutes before serving to allow the sauce to set

Ingredients

Vegetables

• 2.5–3 lbs Yukon gold potatoes, thinly sliced (1/8 inch; no need to peel)
• 1 medium onion, diced
• 8–10 cloves garlic, minced

Dairy & Pantry

• 1/4 cup butter
• 1/4 cup all-purpose flour
• 2 cups milk
• 1 cup chicken broth (use vegetable broth for a vegetarian version)
• 1/2 teaspoon dried thyme
• 1 teaspoon salt

Cheeses

• 1 cup cheddar cheese, shredded
• 1 cup mozzarella cheese, shredded
• 3/4 cup Parmesan cheese, grated

Step-by-Step Instructions

1. Preheat your oven to 350°F.
2. Scrub and slice the potatoes into 1/8-inch rounds using a mandoline slicer or sharp knife. Set them aside.
3. In a medium saucepan over medium heat, melt the butter.
4. Add the diced onion and minced garlic. Sauté for 1 to 2 minutes until the onion is soft and fragrant, but not browned.
5. Stir in the flour to form a roux. Cook for about 1 minute, stirring constantly.
6. Gradually whisk in the milk and chicken broth. Add dried thyme and salt.
7. Continue stirring and bring the mixture to a gentle boil. Cook until the sauce thickens slightly.
8. Remove from heat and stir in the shredded cheddar, mozzarella, and Parmesan. Mix until the cheeses mostly melt into the sauce.
9. Lightly grease a 9″x13″ baking dish.
10. Layer one-third of the sliced potatoes evenly in the dish. Pour one-third of the cheese sauce over the potatoes. Repeat the layering two more times, ending with the remaining cheese sauce on top.
11. Cover the dish tightly with aluminum foil and bake for 30 minutes.
12. Remove the foil and bake for another 35 to 45 minutes, or until the top is golden brown and the potatoes are fork tender.
13. Let the dish rest for 10 minutes before serving.

Variations and Additions

• Swap mozzarella for Gruyère for a nutty, upscale flavor
• Add a pinch of smoked paprika or cayenne for mild heat
• Use vegetable broth instead of chicken broth to make it fully vegetarian

Common Mistakes to Avoid

To get the most out of your cheesy garlic scalloped potatoes, avoiding a few common pitfalls is essential. These mistakes often result in undercooked potatoes, grainy sauce, or uneven textures. Follow the recommendations below to ensure every layer is perfect.

Mistake 1: Slicing Potatoes Too Thick

Thicker slices take longer to cook and may remain firm even after baking. Stick to 1/8-inch slices using a mandoline or sharp knife for even cooking.

Solution: Use a mandoline slicer for consistency and speed. Thinner slices ensure the layers bake evenly and absorb the creamy sauce properly.

Mistake 2: Not Coating All Potatoes in Sauce

Dry spots in the casserole usually result from uncoated potatoes. The sauce must reach every corner and coat every slice.

Solution: Spread each layer of cheese sauce evenly over the potato layers. Use a spatula to gently press down and allow the sauce to settle between slices.

Mistake 3: Rushing the Sauce

A grainy or separated sauce is often the result of too much heat or not enough stirring.

Solution: Cook the roux over medium heat, and whisk continuously when adding milk and broth. Stir until the sauce reaches a smooth, velvety texture before adding cheese.

Mistake 4: Skipping Rest Time

Cutting into the dish immediately after baking causes the sauce to spill and not set properly.

Solution: Let the dish rest for at least 10 minutes before serving. This gives the sauce time to thicken and makes slicing easier.

Recommended Side Dishes

Pairing cheesy garlic scalloped potatoes with the right main and sides brings balance to your plate. Because the potatoes are rich and creamy, lighter or contrast-driven sides work best to round out the meal.

Here are eight excellent side dish ideas to complement your potatoes:

1. Grilled Ribeye Steak

A tender, juicy ribeye pairs beautifully with the creamy richness of the potatoes. The char on the steak adds contrast to the soft texture of the scalloped layers.

2. Honey Glazed Ham

The salty-sweet flavor of baked ham brings out the savory depth of garlic and cheese in the potatoes. Perfect for holiday meals.

3. Baked Salmon with Lemon Dill

Salmon adds a lighter, fresh protein to the plate. The citrus and herb notes help cut through the richness of the cheese sauce.

4. Garlic Herb Roast Chicken

Roast chicken with crisp skin and simple herbs makes a well-balanced pairing. The mild flavor lets the potatoes shine without overwhelming the dish.

5. Sautéed Green Beans with Almonds

For a crisp, green vegetable option, green beans add freshness and crunch. The toasted almonds give a nutty contrast to the soft potatoes.

6. Roasted Brussels Sprouts

Slightly bitter and deeply roasted Brussels sprouts bring earthy balance and texture. They pair well with the creamy garlic profile.

7. Bacon-Wrapped Asparagus

Smoky bacon and tender asparagus create a flavorful side with a bit of salt and snap. It adds complexity without stealing the spotlight.

8. Classic Caesar Salad

A crisp Caesar salad with romaine, Parmesan, and a tangy dressing offsets the creaminess and adds a refreshing contrast.

Tips for Pairing Sides

When choosing side dishes or mains, keep balance in mind. The richness of cheesy garlic scalloped potatoes calls for either lighter flavors that cleanse the palate or equally indulgent items for a fully hearty experience.

For formal dinners, consider pairing with roasted meats and a fresh vegetable dish. For casual meals, combine with simple proteins and a green salad for a complete plate that’s satisfying without being overwhelming.

Pro Tips for Perfect Cheesy Garlic Scalloped Potatoes

Making cheesy garlic scalloped potatoes from scratch is simple, but a few expert tips can take this dish from good to unforgettable. Whether you’re preparing it for the first time or looking to refine your technique, these practical suggestions will help ensure every layer is creamy, flavorful, and fully cooked.

Use Yukon Gold Potatoes

Yukon golds are ideal for scalloped potatoes because of their buttery texture and ability to hold their shape during baking. Their thin skin also means no peeling is required, saving time and effort.

Shred Cheese Fresh

Pre-shredded cheese contains anti-caking agents that prevent smooth melting. Shred your own cheddar, mozzarella, and Parmesan to get the best creamy texture in your sauce.

Add Garlic Toward the End of Sautéing

Garlic can burn quickly if overcooked. Add it after the onions have softened to ensure the garlic becomes fragrant without turning bitter.

Don’t Rush the Roux

Allow the butter and flour mixture to cook for about one minute before adding liquid. This removes any raw flour taste and helps develop a more flavorful sauce.

Broil Briefly for a Crispy Top

After baking, broil the dish for 1 to 2 minutes to create a beautifully golden, slightly crisp top layer. Watch carefully to avoid burning.
