• 1 large egg
• 1/2 cup (50 g) grated Parmesan cheese
• 2 garlic cloves, minced
• 1 tsp dried oregano
• 1/2 tsp salt
• 1/4 tsp black pepper

For the Creamy Sauce

• 2 tbsp butter
• 2 tbsp all-purpose flour

• 1/4 tsp nutmeg
• 1/2 tsp salt

For the Topping

• 1/3 cup (40 g) walnuts or pecans, roughly chopped
• 1 tbsp fresh parsley, chopped

How to Make It

1. Roast the Vegetables

Preheat your oven to 425°F (220°C). Place the sweet potato slices and butternut squash cubes in a large bowl. Add the olive oil, garlic powder, dried thyme, sage, smoked paprika, salt, and black pepper. Toss thoroughly until the vegetables are evenly coated.

Spread them in a single layer on a large baking sheet. Roast for 25–35 minutes, turning halfway through, until tender and lightly caramelized around the edges. Remove from the oven and reduce the oven temperature to 375°F (190°C).

2. Prepare the Ricotta Filling

In a large mixing bowl, combine the ricotta, feta, egg, Parmesan, minced garlic, dried oregano, salt, and black pepper. Stir until creamy and well combined. Set aside while you prepare the remaining components.

3. Cook the Noodles

Cook the lasagna noodles according to the package directions until just al dente. Drain them carefully and lay them flat on a clean surface so they don’t stick together.

4. Make the Creamy Sauce

Melt the butter in a saucepan over medium heat. Whisk in the flour and cook for about 1 minute, stirring constantly.

Gradually whisk in the milk until smooth and free of lumps. Bring the mixture to a gentle simmer and cook for 3–5 minutes, stirring frequently, until slightly thickened.

Stir in the Parmesan, nutmeg, salt, and black pepper. Continue stirring until the Parmesan melts into the sauce. Remove from the heat.

5. Assemble the First Layer

Spread a thin layer of the creamy sauce over the bottom of a 9 × 13-inch (23 × 33 cm) baking dish. Arrange 3 lasagna noodles over the sauce.

Spread approximately one-third of the ricotta-feta mixture over the noodles, followed by one-third of the roasted sweet potatoes and butternut squash.

6. Continue Layering

Add another layer of lasagna noodles, followed by another portion of the ricotta mixture, roasted vegetables, and creamy sauce. Repeat the layering once more until the ingredients are used, finishing with a final layer of noodles and a generous coating of creamy sauce.

7. Add the Cheese

Sprinkle the shredded mozzarella and grated Parmesan evenly over the top. Make sure the cheese reaches close to the edges for a beautifully golden, bubbling crust.

8. Bake Covered

Cover the baking dish tightly with aluminum foil. Bake at 375°F (190°C) for 30 minutes. The foil helps keep the lasagna moist while the layers heat through.

9. Finish Baking

Remove the foil and return the lasagna to the oven. Bake for another 15–20 minutes, until the cheese is melted, bubbling, and golden around the edges.

10. Toast the Nuts

While the lasagna rests, place the chopped walnuts or pecans in a dry skillet over medium-low heat. Toast for 3–4 minutes, stirring frequently, until fragrant and lightly golden. Remove from the heat and let them cool slightly.

11. Rest the Lasagna

Remove the lasagna from the oven and let it rest for 10–15 minutes before slicing. This allows the creamy layers to set and makes the lasagna easier to portion without the layers sliding apart.

12. Garnish

Scatter the toasted walnuts or pecans over the top. Finish with fresh parsley and thyme leaves for a fresh, colourful contrast against the golden cheese.

13. Serve

Slice the lasagna into generous portions and serve warm. Each serving combines creamy cheese, sweet roasted vegetables, tender pasta, silky Parmesan sauce, and crunchy toasted nuts.

Why This Recipe Works

This lasagna brings together several complementary textures and flavours in every layer. Roasting the sweet potatoes and butternut squash first concentrates their natural sweetness while giving them lightly caramelized edges.

The ricotta and feta filling adds a creamy, tangy contrast to the sweet vegetables, while mozzarella and Parmesan create a rich, golden topping. The creamy Parmesan sauce ties everything together and keeps the lasagna moist and comforting.

Finally, toasted walnuts or pecans add a satisfying crunch that contrasts beautifully with the soft vegetables and creamy cheese. The fresh parsley and thyme provide a bright herbal finish.

Tips for the Best Butternut Sweet Potato Lasagna

• Roast the vegetables well: Don’t overcrowd the baking sheet. Space between the pieces helps them caramelize instead of steaming.
• Don’t overcook the noodles: Cook them just until al dente so they maintain their structure during baking.
• Whisk the sauce continuously: Gradually adding the milk while whisking helps create a smooth, lump-free Parmesan sauce.
• Let it rest: Resting for 10–15 minutes makes the layers much easier to slice and serve.
• Toast the nuts: A few minutes in a dry skillet brings out their natural oils and makes them much more fragrant.
• Use fresh herbs: Parsley and thyme add freshness that balances the rich cheese and creamy sauce.

Serving Suggestions

Serve this lasagna with a crisp green salad dressed with lemon vinaigrette for a fresh contrast to the creamy baked layers. Roasted Brussels sprouts, steamed green beans, or a simple arugula salad also make excellent side dishes.

For a cozy holiday meal, pair it with roasted vegetables, crusty bread, or a light seasonal salad. It is hearty enough to serve as a vegetarian main course and elegant enough for a special family dinner.

Frequently Asked Questions

Can I make this lasagna ahead of time?

Yes. You can assemble the lasagna ahead of time, cover it tightly, and refrigerate it until you’re ready to bake. Allow a little extra baking time if the dish goes into the oven directly from the refrigerator.

Can I use canned pumpkin instead of fresh butternut squash?

Fresh roasted butternut squash works best for this recipe because it provides texture and caramelized edges. Canned pumpkin has a softer consistency and is better suited to sauces or fillings.

Can I substitute another cheese for feta?

Yes. Goat cheese can be used for a tangy, creamy alternative. You can also increase the ricotta if you prefer a milder filling.

Can I use no-boil lasagna noodles?

Yes. No-boil noodles can work well, especially because the creamy sauce provides moisture. Follow the package instructions and make sure the noodles are well covered with sauce before baking.

Can I use pecans instead of walnuts?

Absolutely. Pecans have a slightly sweeter, buttery flavour and pair especially well with roasted sweet potatoes and butternut squash.

How should I store leftovers?

Allow the lasagna to cool, then cover it tightly and refrigerate. Reheat individual portions in the microwave or larger portions in the oven until hot throughout.
