Why You'll Love This Recipe
About the Ingredients
2 pounds (900g) Yukon Gold potatoes, thinly sliced (about 1/8 inch thick)
Yukon Golds hold their shape well and have a buttery flavor. You can also use russets, but they may break down more. No need to peel if you prefer a rustic look.
2 cups (480ml) heavy cream
Heavy cream gives the richest texture. For a lighter option, use half-and-half, but the sauce won't be as thick.
4 cloves garlic, minced
Fresh garlic is best for flavor. You can use 1 teaspoon of garlic powder in a pinch, but fresh is more aromatic.
1 cup (100g) freshly grated Parmesan cheese, divided
Freshly grated Parmesan melts and browns better than pre-shredded. If you don't have Parmesan, Pecorino Romano works well.
1 teaspoon salt
Adjust to your taste; if you use salted butter, reduce the salt.
1/2 teaspoon black pepper
Freshly ground black pepper adds a nice kick.
1 teaspoon fresh thyme leaves (optional)
Thyme adds an earthy note. You can substitute 1/2 teaspoon dried thyme.
1 tablespoon butter, for greasing the dish
Use unsalted butter to control the salt level.
Tips & Tricks
- Slice potatoes uniformly using a mandoline or sharp knife to ensure even cooking.
- Soak sliced potatoes in cold water for 30 minutes to remove excess starch, then pat dry – this prevents a gummy texture.
- Don't skip resting the bake after it comes out of the oven – it helps the layers set for cleaner slices.
Pro Tips
Step-by-Step Instructions
1. Preheat and Prep
Preheat oven to 375°F (190°C). Butter a 9×13-inch baking dish. Rinse potato slices and pat dry with a clean towel.
2. Make Garlic Cream
In a medium bowl, whisk together heavy cream, minced garlic, 1/2 cup of Parmesan, salt, pepper, and thyme (if using). Set aside.
3. Layer Potatoes
Arrange a third of the potato slices in the bottom of the prepared dish, overlapping slightly. Pour a third of the cream mixture over the top. Repeat layers twice, ending with the remaining cream. Sprinkle the remaining 1/2 cup Parmesan over the top.
4. Cover and Bake
Cover the dish tightly with foil and bake for 30 minutes at 375°F (190°C). This steams the potatoes and helps them cook through.
5. Uncover and Brown
Remove the foil and continue baking for 20-25 minutes, until the top is golden brown and the edges are bubbling. The potatoes should be tender when pierced with a knife.
6. Rest and Serve
Let the bake rest for 10 minutes before serving. This allows the sauce to thicken and set. Garnish with extra thyme if desired.
Delicious Variations
Add protein
Layer in cooked, crumbled bacon or diced ham between the potato layers for a heartier dish.
Make it cheesy
Swap half the Parmesan for shredded Gruyère or cheddar for a different flavor profile.
Add veggies
Sautéed mushrooms or spinach can be added between layers for extra nutrients.
How to Store Creamy Garlic Parmesan Potato Bake

Frequently Asked Questions
Q: Can I make this potato bake ahead of time?
Yes, you can assemble the dish (without baking) up to 24 hours in advance. Just cover and refrigerate, then bake as directed, adding 10-15 minutes to the covered baking time.
Q: What potatoes are best for scalloped potatoes?
Yukon Gold or russet potatoes are best. Yukon Golds are creamy and hold their shape, while russets are starchy and absorb the sauce well.
Q: Can I use milk instead of heavy cream?
Yes, you can use whole milk or half-and-half, but the sauce will be thinner and less creamy. If using milk, add 1 tablespoon of flour to thicken it.
Q: Why are my potatoes still hard after baking?
If the potatoes are hard, they likely weren't sliced thin enough or the dish wasn't covered long enough. Ensure slices are 1/8-inch thick and bake covered for the full 30 minutes.
