Ingredients:

- 4 large sweet potatoes (about 3 pounds), peeled and thinly sliced – I always go for fresh, firm sweet potatoes with a bright orange color – it makes the dish look vibrant and taste naturally sweet.
- 4 cloves garlic, minced – Garlic is the heart of this Garlic Scalloped Sweet Potatoes recipe. Fresh, minced garlic gives it that authentic garlicky bite you want, but if you’re pressed for time, jarred minced garlic can work in a pinch.
- 1 ½ cups heavy cream – This makes our dish creamy without being overpowering — the perfect base for a creamy sweet potato casserole.
- 1 cup shredded sharp cheddar cheese – You can swap with Gruyère or even mozzarella for a different cheesy touch, but cheddar gives that rich, cheesy sweet potato bake flavor I adore.
- 2 tablespoons unsalted butter – Helps the scalloped potatoes turn golden and rich.
- 1 teaspoon salt – Adjust according to taste, but don’t skip it — it brings out the flavors beautifully.
- ½ teaspoon black pepper – Adds a slight warmth.
- 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme) – This herb gives a fresh note like in a herbed sweet potato gratin — a little twist that brightens the dish.
- Optional: ½ cup grated Parmesan for topping – For that extra crusty topping that makes this baked scalloped potatoes dish hard to resist.
When you’re shopping for ingredients, you can usually find all of these at your local grocery store’s produce and dairy sections. For the cheese, I often grab blocks and shred at home because it melts better in the creamy sweet potato casserole compared to pre-shredded varieties. Here’s a tip I learned from my mom when making Garlic Scalloped Sweet Potatoes: If you’re short on time, slice your sweet potatoes with a mandoline. It saves a lot of peeling and slicing headaches. Also, if you end up with leftover sweet potatoes, you can steam them lightly and store for other uses like garlic mashed sweet potatoes or sweet potato gratin. This keeps the prep efficient during busy weeks.
If you want to save a bit, farmers’ markets often have great deals on sweet potatoes during the fall, and buying in bulk or on sale can be a smart move. Plus, heavy cream can be pricey, but swapping half for whole milk lightly thinned with cream doesn’t hurt the flavor much if you’re trying to keep costs down.

How to Make Garlic Scalloped Sweet Potatoes – Step-by-Step:
1. Preheat your oven to 375°F (190°C). While your oven warms, gather all your ingredients; it’s great to have everything ready to go before you assemble your Garlic Scalloped Sweet Potatoes.
2. Prepare your baking dish by greasing it with butter. This keeps the potatoes from sticking and helps give that cheesy sweet potato bake a golden crust.
3. In a saucepan, heat the heavy cream with minced garlic, salt, pepper, and thyme. Don’t let it boil, just simmer gently for about 5 minutes so the garlic infuses into the cream — this is when the magic starts for your creamy sweet potato casserole! You’ll want it smelling aromatic, with that garlicky richness filling your kitchen.
4. Layer the thinly sliced sweet potatoes into the baking dish. Try to overlap the slices slightly, almost like a puzzle, which helps with even cooking. Don’t worry if your Garlic Scalloped Sweet Potatoes isn’t perfectly layered at first — it never is for me. The key is the cream will help everything meld together while baking.
5. Pour the cream mixture evenly over the potatoes. This ensures every slice gets bathed in creamy garlic goodness.
6. Sprinkle shredded cheddar cheese over the top. If you’re a cheese lover like my family, don’t hold back — and sprinkle that optional Parmesan on top for a golden crust.
7. Dot with small pieces of butter evenly around the dish. This adds richness and helps those baked scalloped potatoes develop a beautiful finish.
8. Cover with foil and bake for 45 minutes. After this, remove the foil and bake uncovered for an additional 20-25 minutes or until the cheese is bubbly and browned, and the sweet potatoes are tender. You’ll know it’s done when you can easily pierce a fork through and the edges are caramelized.
9. Let the Garlic Scalloped Sweet Potatoes rest for 10 minutes before serving. This helps it set a bit so you can serve nice squares without it falling apart.
In my kitchen, Garlic Scalloped Sweet Potatoes usually takes about 75 minutes from start to finish, but it’s worth every bit as you wait for the aroma to fill the room. While it’s baking, I like to prep simple salads or make garlic mashed sweet potatoes if I want another side on hand. If you find yourself short on time, try partially cooking your sweet potatoes by boiling for 5 minutes before layering — it cuts down overall bake time.

A mandoline slicer is my best friend here. It ensures even thin slices which cook uniformly. Without one, use a sharp knife and go slow to keep the layers neat.

Nope, you can experiment with Gruyère, mozzarella, or even a mix for different flavor profiles. I sometimes use smoked gouda for a fun twist that my family loves.

Definitely. Rosemary, sage, or parsley all complement garlic beautifully. I mix fresh herbs into the cream, then sprinkle a few more on top for garnish.
