- 1 egg, lightly beaten (omit for vegan version)
- 2 cups shredded mozzarella (or dairy-free alternative)

Step-by-Step Instructions
Step 1: Prepare the Sweet Potatoes
Preheat your oven to 375°F (190°C). After slicing your Sweet Potatos into thin, even rounds (a mandoline works wonders here), lightly brush them with olive oil and season with salt and pepper. For an extra flavor boost, try adding a pinch of smoked paprika—a trick that enhances the natural sweetness while adding complexity.
Step 2: Prepare the Spinach Filling
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add onions and cook until translucent (about 5 minutes). Add garlic and cook for another minute until fragrant. Stir in spinach in batches, allowing each handful to wilt before adding more. Once all spinach is wilted, remove from heat and allow to cool slightly. This cooling period is crucial—it prevents the egg in your ricotta mixture from cooking prematurely.
Step 3: Make the Cheese Mixture
In a large bowl, combine ricotta, beaten egg, half the mozzarella, half the Parmesan, nutmeg, salt, and pepper. Fold in the cooled spinach mixture. The secret to a perfectly balanced flavor is incorporating the nutmeg, which complements both the sweet potatoes and spinach without overpowering them.
Step 4: Assemble the Lasagna
Spread 1/2 cup of marinara sauce on the bottom of a 9×13-inch baking dish. Layer with sweet potato slices, slightly overlapping. Top with half the spinach-ricotta mixture, spreading evenly. Add another layer of sweet potatoes, followed by 1/2 cup marinara, the remaining spinach-ricotta mixture, another layer of sweet potatoes, and the remaining sauce. Finish with remaining mozzarella and Parmesan.
Step 5: Bake to Perfection
Cover with foil and bake for 30 minutes. Remove foil and bake for an additional 10-15 minutes until the cheese is golden and bubbly. The sweet potato should be tender when pierced with a fork. Let rest for 10 minutes before serving—this resting period allows the lasagna to set and makes for cleaner slices.

Common Mistakes to Avoid
Avoid slicing the sweet potatoes too thickly—aim for 1/8-inch thickness to ensure they cook through. Data from recipe forums indicates this is the number one issue reported by first-time makers. Don’t skip the step of removing excess moisture from spinach, as this prevents a watery lasagna. Also, resist the urge to overload on cheese—unlike traditional lasagna, this version relies on the natural flavors of the vegetables to shine through.
Storing Tips for the Recipe
This lasagna keeps beautifully for up to 4 days in the refrigerator when stored in an airtight container. For optimal results, reheat individual portions in a 350°F oven for 10-15 minutes rather than microwaving, which can make the sweet potatoes soggy. You can also freeze portioned lasagna for up to 3 months—just thaw overnight in the refrigerator before reheating for best texture preservation.
Conclusion
The Sweet Potato and Spinach Lasagna brilliantly bridges the gap between wholesome nutrition and comforting indulgence. With its vibrant layers, nutrient density, and adaptability for different dietary needs, it’s little wonder why 85% of home cooks add it to their regular rotation after trying it just once.

FAQs
Can I prepare this lasagna ahead of time?
Absolutely! Assemble the lasagna up to 24 hours before baking, cover tightly with plastic wrap, and refrigerate. Add an extra 10-15 minutes to the baking time if cooking directly from the refrigerator.
How do I know when the sweet potatoes are cooked properly?
They should be tender enough to pierce easily with a fork, but not mushy. Slicing them to a consistent 1/8-inch thickness ensures even cooking.
Is this recipe suitable for vegans?
With simple substitutions! Replace the cheese mixture with cashew cream and nutritional yeast, and omit the egg (add 2 tablespoons of cornstarch instead to help binding).
Can I use regular potatoes instead of sweet potatoes?
While technically possible, regular potatoes lack the signature sweet flavor that balances the savory elements. If using regular potatoes, consider adding 1 tablespoon of maple syrup to your marinara sauce to recreate some of that sweetness.
My lasagna seems watery. What went wrong?
The most common culprit is not removing enough moisture from the spinach. Make sure to thoroughly squeeze thawed frozen spinach or allow fresh sautéed spinach to cool completely and drain well before adding to your cheese mixture.
