How to Make Sweet Potato, Spinach & Goat Cheese Lasagna

Step 1: Roast the Sweet Potatoes

Preheat the oven to 400°F (200°C).

Arrange the thinly sliced sweet potatoes on a baking sheet. Brush them lightly with olive oil and season with salt, black pepper, dried thyme and oregano.

Roast for 18–22 minutes, turning the slices halfway through, until tender but still firm enough to hold their shape when layered.

Step 2: Prepare the Spinach

Heat a skillet over medium heat and add a little olive oil. Add the minced garlic and cook for about 30 seconds, until fragrant.

Add the fresh spinach and cook for 2–3 minutes, stirring occasionally, until wilted. Season lightly with salt and black pepper, then set aside.

Step 3: Prepare the Goat Cheese

Place the goat cheese in a bowl and gently soften it with a fork.

If the cheese is particularly firm, add 1–2 tablespoons of warm water or milk and mix until it becomes easier to spread between the layers.

Step 4: Toast the Walnuts

Heat a dry skillet over medium heat. Add the chopped walnuts and toast for 2–3 minutes, stirring frequently so they become fragrant without burning.

Remove from the heat and set aside.

Step 5: Build the Lasagna

Lightly grease a baking dish.

Arrange a layer of roasted sweet potato slices across the bottom of the dish. Add some of the wilted spinach, small pieces of goat cheese and a sprinkle of grated mozzarella or Parmesan.

Step 6: Repeat the Layers

Continue layering the sweet potato, spinach, goat cheese and grated cheese until all the ingredients have been used.

Finish with the remaining grated cheese and toasted walnuts, creating a golden topping with plenty of texture.

Step 7: Bake

Cover the baking dish loosely with foil and bake at 375°F (190°C) for 20 minutes.

Remove the foil and continue baking for another 15–20 minutes, until the cheese has melted and the top is lightly golden.

Step 8: Make the Maple Honey Sauce

While the lasagna is baking, combine the maple syrup, honey, balsamic vinegar, Dijon mustard, fresh thyme and salt in a small saucepan.

Warm gently over low heat for 2–3 minutes, stirring until the sauce becomes smooth and glossy.

Step 9: Rest and Serve

Remove the lasagna from the oven and allow it to rest for 10 minutes before slicing.

Drizzle the warm maple honey sauce generously over the top and finish with extra toasted walnuts and fresh herbs.

Serve warm and enjoy the combination of creamy goat cheese, sweet roasted potatoes, tender spinach and crunchy walnuts.

Serving Suggestions

Serve with a simple green salad dressed with lemon vinaigrette.
Pair with roasted seasonal vegetables.
Add warm crusty bread on the side.
Serve with extra maple honey sauce for drizzling.
Garnish with fresh thyme or parsley for a fresh finish.

Helpful Tips

Slice the sweet potatoes evenly: Similar-sized slices will roast more consistently and make the layers easier to build.
Don’t overcook the sweet potatoes: They should be tender but firm enough to maintain their shape during assembly.
Drain the spinach well: Removing excess moisture helps prevent the lasagna from becoming watery.
Soften the goat cheese: A little warm water or milk can make firm goat cheese much easier to spread.
Watch the walnuts: They toast quickly, so stir frequently and remove them from the heat once fragrant.
Let it rest: Allowing the lasagna to sit for 10 minutes makes it easier to slice and serve neatly.

Recipe Variations

Use mozzarella instead of Parmesan for a softer, more melty topping.
Use Parmesan for a more savoury, golden finish.
Swap the walnuts for another nut if preferred.
Add extra fresh herbs before serving for a brighter finish.
Adjust the maple honey sauce to your preferred balance of sweetness and tang.

Storage

Store leftover lasagna in an airtight container in the refrigerator. Reheat gently until warmed through and add fresh maple honey sauce and toasted walnuts before serving if desired.
