Golden Zucchini & Sweet Potato Rosti Lasagna Rolls with Spinach, Feta & Ricotta
These Lasagna Rolls are a creative vegetarian dinner that combines crisp golden zucchini and sweet potato rosti with tender pasta, creamy ricotta, salty feta, and fresh spinach. The result is comforting, colorful, and packed with contrasting textures. Instead of using a traditional meat filling, this recipe layers roasted vegetables and a creamy spinach-cheese mixture inside lasagna sheets before baking them in a rich tomato sauce.
The idea behind these Lasagna Rolls is to take the familiar comfort of baked lasagna and give it a more vegetable-forward Mediterranean-inspired character. Sweet potato brings natural sweetness, zucchini keeps the filling fresh, and the rosti-style preparation adds browned, crisp edges. Ricotta creates a soft creamy center, while feta adds a tangy salty flavor that balances the vegetables.
These Lasagna Rolls are ideal for a family dinner, weekend meal, vegetarian gathering, or make-ahead lunch. They can be assembled earlier in the day and baked when needed. A simple tomato sauce provides moisture and acidity while helping the pasta become tender and flavorful. These Lasagna Rolls are perfect for a comforting vegetarian family dinner.

Step-by-Step Instructions
1. Prepare the Zucchini and Sweet Potato
Start by grating the zucchini and sweet potato using the large holes of a box grater. Place the grated zucchini in a clean kitchen towel and squeeze firmly to remove as much liquid as possible. Repeat with the sweet potato.
This step is especially important because zucchini contains a significant amount of water. If you leave too much moisture in the vegetables, the rosti mixture can become loose and difficult to brown.
Place the drained vegetables in a large bowl. Add the grated onion, eggs, breadcrumbs, flour, garlic powder, oregano, smoked paprika, salt, and black pepper. Mix until everything is evenly combined.
The vegetable mixture should hold together when pressed. If it seems too wet, add another tablespoon of breadcrumbs.
2. Cook the Golden Rosti
Heat the olive oil in a large nonstick skillet over medium heat. Add the vegetable mixture in small portions, pressing each portion into a thin round or oval shape.
Cook for approximately 3–4 minutes on the first side, until the underside becomes golden and crisp. Carefully flip and cook another 3–4 minutes.
Continue until the mixture is used. You do not need to cook the rosti completely dry because it will finish cooking inside the baked pasta.
Allow the cooked rosti to cool for several minutes. Cut or tear each piece into strips that will fit comfortably inside the pasta sheets.
The browned vegetable layer gives these Lasagna Rolls their distinctive golden appearance and adds a lightly crisp texture to the creamy filling.
3. Prepare the Spinach
Wash the spinach thoroughly. Place it in a large skillet over medium heat and cook for 2–3 minutes, stirring until wilted.
Transfer the spinach to a colander and let it cool slightly. Squeeze out as much water as possible, then chop it finely.
If you use frozen spinach instead, thaw it completely and squeeze it very well before chopping.
Keeping the spinach relatively dry is important because excess liquid can make the Lasagna Rolls watery after baking.
4. Make the Spinach, Feta and Ricotta Filling
Add the prepared spinach to a large bowl. Stir in the ricotta, feta, mozzarella, minced garlic, oregano, basil, black pepper, lemon zest, lemon juice, and red pepper flakes if using.
Mix gently until the ingredients are evenly distributed.
Taste the filling and adjust the seasoning if necessary. Remember that feta already contains salt, so you may not need additional salt.
The lemon zest and juice brighten the rich cheese mixture and make the Lasagna Rolls taste fresh rather than heavy.
5. Prepare the Tomato Sauce
Heat two tablespoons of olive oil in a saucepan over medium heat. Add the chopped onion and cook for 4–5 minutes until softened.
Add the garlic and cook for about 30 seconds. Pour in the crushed tomatoes or passata.
Add oregano, basil, smoked paprika, salt, and black pepper. If the tomatoes are particularly acidic, add a teaspoon of honey or maple syrup.
Simmer the sauce for 12–15 minutes, stirring occasionally. The sauce should become slightly thick but still pour easily.
A flavorful tomato sauce gives the Lasagna Rolls moisture while adding acidity that balances the sweet potato and creamy cheese.
6. Cook the Pasta Sheets
Bring a large pot of salted water to a boil. Cook the lasagna sheets according to the package directions until just tender.
Do not overcook them. The sheets should remain firm enough to handle and roll without tearing.
Drain the pasta and lay the sheets flat on a lightly oiled tray or clean work surface.
If you are using oven-ready sheets, follow the package instructions. Some oven-ready varieties can be assembled without pre-boiling.
7. Assemble the Lasagna Rolls
Preheat the oven to 375°F (190°C). Spread about one cup of tomato sauce across the bottom of a 9 × 13-inch baking dish.
Place one pasta sheet on a clean surface. Spread a thin, even layer of spinach, feta, and ricotta filling across the sheet.
Place a strip of golden zucchini and sweet potato rosti over the filling. Roll the pasta gently from one short end toward the other.
Place the finished roll seam-side down in the baking dish.
Repeat with the remaining pasta sheets and filling. Arrange the Lasagna Rolls snugly beside one another so they remain upright during baking.
Pour the remaining tomato sauce over the top, making sure the pasta is well covered.
8. Add the Cheese
Sprinkle shredded mozzarella evenly over the rolls. Add crumbled feta and Parmesan if using.
For extra Mediterranean flavor, sprinkle a little oregano and black pepper over the cheese.
The combination of mozzarella and feta creates a golden, bubbling topping while keeping the interior creamy.
9. Bake
Cover the baking dish loosely with aluminum foil. Bake for 25 minutes.
Remove the foil and continue baking for another 15–20 minutes, until the cheese is melted and lightly golden and the sauce is bubbling around the edges.
For a darker top, use the broiler for the final 1–2 minutes. Watch carefully because the cheese can brown quickly.
The Lasagna Rolls are ready when the center is hot and the pasta is completely tender.
10. Rest Before Serving
Remove the baking dish from the oven and let it rest for about 10 minutes.
Resting allows the sauce and cheese to settle, making the rolls easier to serve without falling apart.
Garnish with fresh parsley or basil and a small drizzle of extra virgin olive oil.
Tips for the Best Results
Remove as Much Vegetable Moisture as Possible
The biggest secret to successful rosti is moisture control. Zucchini contains a lot of water, and sweet potato can also release moisture during cooking.
Squeeze both vegetables thoroughly before mixing the rosti. This helps them brown instead of steam.
Dry spinach is equally important. If the spinach is wet, the cheese filling can become loose and may release liquid into the dish.
Do Not Overfill the Pasta
Use a moderate amount of filling on each sheet. Too much filling makes the rolls difficult to close and can cause the mixture to spill out during baking.
A thin layer of ricotta mixture plus a strip of rosti is enough to create a satisfying center.
Keep the Sauce Thick
The tomato sauce should not be watery. Simmer it long enough to reduce excess liquid.
A thick sauce helps the Lasagna Rolls maintain their shape and prevents the finished dish from becoming soupy.
Roll Gently
Cooked pasta sheets are delicate. Roll them firmly enough to hold their shape but do not press so hard that the filling is forced out.
Placing each roll seam-side down helps it stay closed. Allow the Lasagna Rolls to rest before serving for the best texture.
Serving Suggestions
Serve these Lasagna Rolls with a crisp green salad dressed with lemon juice and olive oil.
A Mediterranean tomato and cucumber salad also pairs beautifully with the rich cheese filling.
For a larger dinner, serve roasted broccoli, asparagus, bell peppers, or a simple arugula salad on the side.
Warm garlic bread or crusty sourdough is useful for soaking up the tomato sauce.
For a Mediterranean-inspired table, add olives, hummus, roasted peppers, and a small bowl of tzatziki.
Serve the Lasagna Rolls with a fresh Mediterranean salad and warm bread.
Recipe Variations
Add Mushrooms
Sauté finely sliced mushrooms until their moisture has evaporated, then add them to the spinach filling.
Mushrooms provide an earthy flavor that works particularly well with feta and sweet potato.
Add Sun-Dried Tomatoes
Chopped sun-dried tomatoes can be mixed into the ricotta filling. Their concentrated sweet-tart flavor adds another Mediterranean element.
Add Roasted Red Pepper
Finely chopped roasted red pepper can be added to the filling or scattered over the tomato sauce.
Make It Spicy
Add extra red pepper flakes to the filling or tomato sauce. A drizzle of chili oil over the finished dish also works well.
Add Fresh Herbs
Fresh basil, parsley, dill, or mint can be added to the cheese filling. Use herbs moderately so they complement rather than overpower the roasted vegetables.
Make-Ahead Instructions
These Lasagna Rolls can be assembled several hours before baking.
Prepare the rosti, spinach filling, and tomato sauce separately. Once they have cooled, assemble the rolls in the baking dish.
Cover tightly and refrigerate for up to 24 hours.
When ready to bake, allow the dish to sit at room temperature for approximately 20 minutes. Bake according to the recipe, adding several extra minutes if the center is still cold.
Storage Instructions
Store leftover rolls in an airtight container in the refrigerator for up to four days.
Reheat individual portions in the microwave until hot throughout. For better texture, reheat them in a covered oven-safe dish at 350°F (175°C).
Add a spoonful of tomato sauce before reheating if the pasta looks dry.
The Lasagna Rolls can also be frozen after baking. Allow them to cool completely, wrap individual portions securely, and freeze for up to three months.
Frequently Asked Questions
Can I use frozen spinach?
Yes. Thaw it completely and squeeze out as much water as possible. Frozen spinach is convenient and works well in the ricotta filling.
Can I use only zucchini for the rosti?
Yes. You can replace the sweet potato with additional zucchini, although the rosti will be less sweet and may need extra breadcrumbs.
Can I prepare the rosti ahead?
Yes. Cooked rosti can be refrigerated for up to two days. Allow it to cool before storing in an airtight container.
Can I use cottage cheese instead of ricotta?
Yes. Cottage cheese can replace ricotta. For a smoother filling, blend it briefly before combining it with the spinach and feta.
Can I make this gluten-free?
Yes. Use gluten-free lasagna sheets and gluten-free breadcrumbs and flour for the rosti.
Why did my rolls become watery?
Excess moisture from zucchini, spinach, or tomato sauce is usually responsible. Squeeze the vegetables thoroughly and simmer the sauce until slightly thickened.
Can I make the recipe without feta?
Yes. You can replace feta with goat cheese or additional mozzarella. The flavor will be milder, but the recipe will still work.
How do I keep the Lasagna Rolls neat when serving?
Let the baked dish rest for about 10 minutes before serving. Use a wide spatula to lift each roll carefully from underneath, keeping the seam and filling intact.
