Creating Easy Sweet Potato Lasagna can be straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
2. Prepare Sweet Potatoes: Peel and slice the sweet potatoes into thin rounds, about 1/4 inch thick.
3. Mix Cheese Filling: In a medium bowl, combine ricotta cheese, egg, Italian seasoning, salt, and pepper. Mix until well blended.
4. Layer Ingredients: Spread a layer of marinara sauce at the bottom of the baking dish.
5. Add Sweet Potatoes: Place a layer of sweet potato slices on top of the sauce, slightly overlapping them.
6. Spread Cheese Mixture: Add half of the ricotta mixture over the sweet potatoes, spreading evenly.
7. Repeat Layers: Add another layer of marinara sauce, followed by sweet potatoes, and top with the remaining ricotta mixture.
8. Finalize with Sauce: Add a final layer of sweet potato slices, cover with the remaining marinara sauce, and sprinkle with mozzarella and Parmesan cheese.
9. Cover with Foil: Cover the baking dish with aluminum foil to prevent the cheese from burning.
10. Bake: Place the dish in the preheated oven and bake for 30 minutes.
11. Uncover and Brown: Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden brown.
12. Cool Down: Remove from the oven and let it cool for 10-15 minutes before slicing.
