Why roast the garlic instead of using it raw?

Roasting the garlic mellows its pungent flavor, transforming it into a sweet, caramelized, and deeply aromatic ingredient that adds complexity to the creamy sauce without harshness.

What kind of sweet potatoes work best for this recipe?

Use large, firm sweet potatoes that can be thinly sliced evenly, such as Beauregard or Jewel varieties, ensuring they cook through consistently and layer well in the pan.

How can I prevent the potato starch from gumming up the sauce?

Whisk the potato starch with a small amount of cold coconut and almond milk until smooth *before* adding it to the boiling milk mixture, then stir constantly for two minutes as it thickens.

Can I prepare these scalloped sweet potatoes ahead of time?

Yes, you can assemble the dish and bake it covered for 30 minutes, then refrigerate. Reheat covered, then uncover and finish baking until fork-tender and browned.

Is there a substitute for potato starch if I don't have it?

While potato starch provides a smooth, clear thickening, you could try using an equal amount of cornstarch or arrowroot powder, whisked in the same manner, though the final texture might vary slightly.

How to Prepare Scalloped Sweet Potatoes [Vegan, Gluten-Free]

Preheat your oven to 400°F and place two squares of tinfoil on top of each other (shiny side up).
Cut the tops of each head of garlic off, so that the tips of each clove are exposed. Peel off any of the large pieces of papery skin. Drizzle the heads with a little bit of olive oil and rub it in. Wrap the tinfoil up like a packet and place in the oven.
Cook until the garlic is tender, about 45 minutes.
Once the garlic has roasted, squeeze the garlic out of its skin and finely chop it. Additionally, reduce the oven temperature to 350°F.
Heat the remaining 2 tablespoons of olive oil up in a very large, oven-safe frying pan, set over medium/high heat. Cook the onion until golden brown and soft, about 5 minutes.
Add 1 cup of coconut milk and 1 cup of almond milk and bring to a boil. While you wait for the liquid to boil, whisk together the remaining 1 tablespoon of coconut milk, 1 tablespoon of almond milk, and 1 1/2 tablespoons of potato starch in a small bowl, until smooth.
Once the milk mixture boils, whisk in the potato starch mixture, stirring constantly so it doesn't gum up in the milk and boil for 2 minutes, again stirring constantly.
Reduce the heat to medium, add the salt, pepper and chopped roasted garlic, and cook the sauce for an additional 5-6 minutes until nice and thick, stirring frequently.
Once the sauce has cooked, add in the thinly sliced potatoes and stir around until they are coated in the sauce. This can get a little messy. Then, move the potatoes around with a spoon until they are in flat layers (see notes).
Cover the pan with tinfoil and place into the oven for 30 minutes. Uncover the pan, press the potatoes down so they really sink into the sauce, and cook and additional 30-40 minutes, until the potatoes are fork-tender and the top is browned. Optionally, you can turn your oven to high broil and broil the potatoes for 3-4 minutes to darken the top.
Let the potatoes stand for 10 minutes and then serve.

Notes

Cornstarch works too, if you're not worried about it being paleo. If you want to serve this in a casserole dish, just layer half the potatoes in a lightly greased casserole dish, pour half the thickened sauce over, and then repeat.
