What Are Sweet Potato Scallops?
Sweet Potato Scallops are not just a pretty face on the dining table; they have deep roots in many culinary traditions. Often celebrated for their nutritious qualities and comforting texture, the origins of scalloped dishes trace back to the 18th century, where layers of anything from potatoes to grains were baked with cream or broth. This modern twist, featuring sweet potatoes, brings a vibrant sweetness to the classic dish.
The taste of Sweet Potato Scallops is a delightful fusion of creamy, sweet, and savory notes. When baked, the sweet potatoes become tender, almost melting in your mouth, while the infused coconut milk creates a rich, luxurious sauce that ties it all together.
You might want to whip up Sweet Potato Scallops for family gatherings, holiday dinners, or simply as a cozy weekend meal. Trust me, once you take a whiff of those herbs mingling in the oven, you’ll understand why this dish holds such a special place in my heart!

Ingredients
1 tbsp coconut oil (or olive oil): Use organic coconut oil for a subtle sweetness or your favorite extra virgin olive oil.
1 can coconut milk (14 oz): Look for full-fat coconut milk for creaminess, or light if you’re watching calories.
1 rosemary sprig (or 2 tbsp dried and crushed): Fresh rosemary offers a robust flavor, but dried is a good substitute in pinch.
2 tsp thyme leaves (fresh or dried): Fresh is always best, but dried will hold well in this recipe too.
2 garlic cloves (minced): Fresh garlic adds exceptional flavor, don’t skip this!
1/2 tsp salt, 1/2 tsp pepper: Adjust to taste, but start with the suggested amounts.
2 tbsp cornstarch: This helps to thicken the sauce; you can swap it with arrowroot if you’re looking for a gluten-free option.
2 sweet potatoes (peeled and sliced into 1/4", about 4 cups): Look for medium-sized, firm sweet potatoes for the best texture.
1 onion (thinly sliced): A sweet onion or yellow onion works beautifully!
Notes
- Quality Matters: Using high-quality ingredients will elevate your dish.
- Prep Tips: Allow the coconut milk to come to room temperature for easier mixing.

Step-by-Step Instructions
Pre-heat your oven: Set it to 400°F (200°C). Lightly grease a 9" oven-safe baking dish with the coconut oil to prevent sticking.
Prepare the sauce: In a saucepan over medium heat, combine the coconut milk, rosemary, garlic, thyme, salt, and pepper. Bring to a boil, whisking occasionally.
Make a slurry: In a small bowl, mix together cornstarch with 1/4 cup cold water until smooth, or shake it in a small jar. This will help thicken the coconut milk sauce.
Thicken the sauce: Whisk the cornstarch slurry into the boiling coconut milk. Keep whisking until it thickens, around 2-3 minutes. Remove the pan from heat and take out the rosemary sprig.
Layer the dish: In your prepared baking dish, layer the sweet potato slices, followed by onion slices, repeating until everything is used up, culminating in a beautiful layered look.
Pour the sauce: Gently pour the garlic and herb-infused coconut milk evenly over the casserole, ensuring all layers are coated.
Bake it up: Cover the dish with foil and bake for 60 minutes. Then, remove the foil and bake for another 15 minutes, allowing the top to get golden and crisp.
Final touch: Remove from the oven and let it rest for 10-15 minutes before serving. This allows the flavors to settle and makes serving easier.
Chef’s Tips
Watch the Timing: Bake time may vary based on the thickness of your sweet potato slices.
Common Mistakes: Make sure to thinly slice your sweet potatoes to ensure they cook through properly.
Professional Techniques: Try using a mandoline slicer for uniform pieces that cook evenly.
Expert Tips & Tricks
Storage Recommendations: Leftovers can be stored in the fridge for up to 3-4 days in an airtight container.
Make-Ahead Instructions: You can prep this dish a day in advance, just store it assembled without baking, and pop it in the oven when you are ready to serve!
Troubleshooting: If your sauce is too thin, try adding more cornstarch mixed with cold water until you achieve the right thickness.
Serving Suggestions
Sweet Potato Scallops pair wonderfully with a simple green salad dressed in a light vinaigrette. A side of roasted Brussels sprouts or garlic green beans adds a delightful crunch. For special occasions, consider garnishing with fresh herbs or a sprinkle of parmesan cheese for added flair. This dish shines during holidays, potlucks, or as an impressive centerpiece for a family dinner.
Variations & Substitutions
Different Flavors: Try adding spices like nutmeg or cinnamon for a warm touch, or even some heat with cayenne pepper or diced jalapeños.
Dietary Restrictions: For a vegan-friendly version, ensure all your sauces and oils are plant-based. If you’re looking to go gluten-free, be sure to use the cornstarch as a thickener instead of flour.
Seasonal Variations: Swap sweet potatoes for other root vegetables like butternut squash or parsnips in the winter, or zucchini in the summer for a lighter dish.
