The Unique “Rösti” Touch
What makes this dish truly extraordinary is the incorporation of the Swiss “Rösti” technique. Shredded russet potatoes and grated butternut squash are combined with garlic powder, dried thyme, and a hint of egg binder, then baked until golden and crispy. This crisp vegetable base absorbs the savory pan juices while offering an addictive golden crunch that conventional pasta dishes lack.
Key Ingredients & Mediterranean Substitutions
To achieve the perfect balance of savory, sweet, creamy, and nutty flavors, every ingredient plays a dedicated role:
1. The Shredded Rösti & Squash Foundation
- Butternut Squash: Peeled and split into two applications—half is grated for the crispy rösti base, and half is diced into sweet, roasted cubes for the rich internal filling.
- Russet Potatoes: Grated finely and squeezed completely dry to provide the ideal starch structure for crisping.
- Extra Virgin Olive Oil (EVOO): Used to brush the baking surfaces and sauté the squash, adding fruitiness and heart-healthy monounsaturated fats.
2. Fresh Baby Spinach, Garlic & Herbs
- Fresh Baby Spinach: Finely chopped and wilted to add vibrant green color, iron, and fresh earthy balance to the rich cheeses.
- Garlic & Herbs: Freshly minced garlic combined with Italian seasoning and dried thyme creates a fragrant aromatic backbone.
3. The Creamy Filling
- Whole-Milk Ricotta: Provides a lush, airy, pillowy structure inside each roll.
- Authentic Greek Feta: Adds a sharp, salty, Mediterranean tang that cuts through the sweetness of the butternut squash. (If you love this combination, be sure to try our recipe for Baked Feta with Giant Beans.)
- Shredded Mozzarella: Creates those irresistible, gooey cheese pulls inside and across the top.
4. Finishing Touches & Health Notes
- Sage Brown Butter & Honey Glaze: Unsalted butter browned to nutty perfection with fresh sage leaves, sweetened with a drizzle of pure honey.
- Toasted Walnuts & Dried Cranberries: Provide crunch, essential Omega-3 fatty acids, and a burst of tart sweetness.
- Health Note: By emphasizing extra virgin olive oil, nutrient-dense leafy greens, and fiber-rich squash, this dish supports heart health while fulfilling comfort food cravings. If you enjoy wholesome winter bakes, check out our Root Vegetable Gratin with Sweet Potatoes, Parsnips and Beets as well.
Step-by-Step Instructions: How to Make Perfect Lasagna Rolls
Step 1: Preparing & Crisping the Shredded Squash & Potato Base
Begin by preheating your oven to 400°F (200°C). Line a large, rimmed sheet pan with parchment paper and brush it lightly with extra virgin olive oil.
Take your grated butternut squash and grated russet potatoes and transfer them into a clean flour-sack kitchen towel. Gather the corners, twist tightly over the sink, and squeeze vigorously. Removing excess liquid is the secret to achieving a crispy texture rather than steamed, soggy vegetables.
In a large bowl, mix the squeezed squash and potatoes with finely chopped baby spinach, a beaten egg, all-purpose flour, garlic powder, dried thyme, sea salt, and black pepper. Press this mixture firmly into a thin, even layer across your prepared baking sheet. Bake for 20 to 25 minutes until the edges turn deep golden brown and set firm.
Step 2: Crafting the Creamy Ricotta-Feta & Spinach Filling
While the rösti base bakes, roast your small butternut squash cubes with a drizzle of olive oil, salt, and pepper until tender and lightly caramelized.
In a medium mixing bowl, blend the whole-milk ricotta, crumbled Greek feta, minced garlic, Italian seasoning, and a pinch of black pepper until smooth. Fold in cooked baby spinach and the roasted butternut squash cubes.

Step 3: Assembling, Rolling, and Baking to Golden Perfection
Boil 8 to 10 wide lasagna noodles in salted water until just al dente, then drain and lay them flat on parchment paper.
Cut your baked rösti sheet into wide strips to line alongside or beneath your pasta noodles. Spread a generous layer of the creamy spinach-ricotta-feta filling across each noodle, sprinkle with shredded mozzarella, and scatter a few extra tender squash chunks over top.
Carefully roll up each noodle from short end to short end into a snug, neat cylinder. Nestled seam-side down in a lightly greased ceramic baking dish over a thin layer of rösti base, top the rolls generously with mozzarella cheese. Bake at 400°F (200°C) for 15 minutes, then switch the broiler to high for 2 to 3 minutes until the cheese forms a blistered, deeply golden crust.
Step 4: Infusing the Sage Brown Butter & Honey-Walnut Glaze
While the lasagna rolls undergo their final bubbling bake, melt 4 tablespoons of unsalted butter in a small skillet over medium heat. Swirl constantly for 3 to 4 minutes as the butter foams and turns a fragrant, amber-brown color.
Toss in fresh sage leaves and chopped walnuts, letting them sizzle and crisp for 60 seconds. Remove from heat immediately and stir in two tablespoons of honey. Once the lasagna rolls emerge hot from the oven, spoon the warm sage brown butter glaze over top, then garnish with dried cranberries and sesame seeds.
Pro Tips for Culinary Success
- Master Moisture Control: The primary enemy of any vegetarian lasagna roll ups recipe is excess water. Always wring out your grated squash, potatoes, and cooked spinach using a kitchen towel.
- Prevent Noodle Cracking: Never roll cold or dry lasagna sheets. Keep your boiled noodles slicked with a tiny drop of olive oil on parchment paper while assembling.
- Achieve the Broiled Golden Crust: Watch the broiler closely during the final 2 minutes. The combination of mozzarella and feta caramelizes quickly under high heat, producing that signature restaurant-style browned top.
Storage, Make-Ahead, and Freezing Instructions
- Refrigerator Storage: Store leftover cooked lasagna rolls in an airtight glass container in the fridge for up to 4 days. Reheat individual portions in an oven preheated to 350°F (175°C) for 12 to 15 minutes to keep the edges crispy.
- Freezing (Unbaked Method): Assemble the rolls completely in an oven-safe baking dish, but withhold the brown butter glaze. Cover tightly with plastic wrap and aluminum foil, then freeze for up to 3 months. Bake from frozen at 375°F (190°C) for 45 to 50 minutes, removing foil halfway through.
- Freezing (Baked Method): Allow fully baked rolls to cool completely. Freeze in single-portion containers. Reheat from thawed in the microwave or oven until piping hot throughout.

Frequently Asked Questions (PAA Focus)
Can I make butternut squash lasagna roll-ups ahead of time?
Yes! You can assemble the rolls up to 24 hours in advance. Cover the baking dish tightly with foil and store it in the refrigerator. When ready to serve, bake as directed, adding 5 extra minutes to the total baking time to account for the chill.
What goes well with butternut squash lasagna rolls?
These rich lasagna rolls pair wonderfully with a light, peppery fresh arugula salad dressed with lemon juice and olive oil, crusty Mediterranean sourdough bread, or roasted broccoli and asparagus.
Can I make this dish gluten-free?
Absolutely. Substitute standard lasagna sheets with certified gluten-free lasagna noodles, and replace the 2 tablespoons of all-purpose flour in the rösti base with a 1:1 gluten-free baking flour or cornstarch binder.
How do I keep the spinach filling flavorful and non-watery?
Squeeze every drop of water out of your wilted spinach before stirring it into the ricotta and feta. Additionally, using real Greek feta adds body and absorbs excess moisture while seasoning the entire filling naturally.
