Instructions
Prepare the Sweet Potatoes
Preheat the oven to 375°F (190°C).
Peel the sweet potatoes and slice them lengthwise into thin strips using a sharp knife or mandoline.
Lightly brush the slices with olive oil and place them on a baking sheet.
Bake for 10 minutes to soften slightly. Remove and set aside.
Prepare the Spinach Filling
Heat 1 tablespoon olive oil in a skillet over medium heat.
Add the garlic and sauté for 30 seconds.
Add the spinach and cook until wilted.
Season with a pinch of salt and pepper.
Remove from heat and allow to cool slightly.
Prepare the Ricotta Mixture
In a large bowl, combine ricotta cheese, egg, nutmeg, thyme, half of the Parmesan cheese, and a pinch of salt and pepper.
Mix until smooth and well blended.
Fold in the cooled spinach mixture.
Make the Cranberry Honey Sauce
In a small saucepan, combine dried cranberries, honey, balsamic vinegar, water, and cinnamon.
Simmer over low heat for 8 to 10 minutes until the cranberries soften and the sauce thickens slightly.
Remove from heat and set aside.
Assemble the Lasagna
Lightly grease a 9×13-inch baking dish.
Arrange a layer of sweet potato slices on the bottom.
Spread a layer of the ricotta-spinach mixture over the sweet potatoes.
Sprinkle with mozzarella cheese.
If using lasagna noodles, place a layer of noodles over the cheese.
Repeat the layers until all ingredients are used, finishing with sweet potatoes and the remaining mozzarella and Parmesan cheese.
Bake
Cover loosely with foil and bake for 35 minutes.
Remove the foil and bake for an additional 10 to 15 minutes until golden and bubbling.
Allow the lasagna to rest for 15 minutes before slicing.
Finish and Serve
Drizzle the cranberry honey sauce over each serving.
Sprinkle with toasted walnuts and fresh parsley or thyme before serving.
Tips
Helpful Tips
Use a mandoline slicer for evenly thin sweet potato slices.
Pre-baking the sweet potatoes helps ensure tender layers.
Squeeze excess moisture from spinach to prevent a watery lasagna.
Allow the spinach mixture to cool before mixing with ricotta.
Use whole milk ricotta for the creamiest texture.
Toast the walnuts before adding them to enhance their flavor.
Let the lasagna rest after baking for cleaner slices.
Do not overcook the cranberry sauce, as it will continue thickening while cooling.
Freshly grated Parmesan melts and tastes better than pre-packaged versions.
Prepare the cranberry sauce ahead of time for easier assembly.
