How to Make Healthy Scalloped Sweet Potatoes
This easy sweet potato recipe is packed with flavor and perfectly savory and delicious.
I do recommend using parchment paper when baking the potato rounds. This helps keep the potatoes from sticking to the baking sheet, plus it makes clean up much easier.


How to Make Low Calorie Scalloped Sweet Potato Casserole:
- Preheat the oven to 425 degrees. Line 2 baking sheets with parchment paper. And spray a 9×13 baking dish with olive oil.
- Add the sweet potato rounds to the prepared baking sheets, spray with olive oil.
- Bake the sweet potato rounds for 20 minutes. Then remove from oven and let cool.
- Meanwhile, add the butter to a large sauce pan and melt over medium heat.
- Add in the onion and cook, stirring often, until softened (about 5 minutes). Add in the garlic and cook for an additional 1 minute.
- Next, add in the flour, salt and pepper and mix together. Cook for 2 minutes, until the flour smell dissipates, then add in the milk and whisk to remove any lumps.
- Increase the heat to medium high and cook, stirring often, until the sauce thickens (about 5 minutes). Then remove from heat and mix in 1/2 of the cheese.
- To assemble: Add 1 layer of the potatoes to the prepared baking dish. Spoon over 1/4 of the sauce. Add another layer of sweet potatoes and sauce, and so on until all of the potatoes and sauce are in the baking dish. Cover with remaining cheese, and spray lightly with olive oil.
- Add the baking dish back to the hot oven and bake for 10 minutes, then broil on low (watch closely so it doesn’t burn) for 2-5 minutes until golden brown and bubbling.
- Remove from the oven and sprinkle over the sage, and let stand 10 minutes to help it hold together.
