Description

This layered sweet potato, butternut squash & carrot lasagna is a beautiful vegetarian twist on traditional lasagna. Instead of pasta and heavy meat sauce, thin layers of roasted sweet potato, buttery butternut squash, and tender carrots are combined with tangy feta and crunchy toasted walnuts. A glossy cranberry-honey drizzle brings everything together with a sweet, tart finish. Similar versions use roasted vegetables, feta, walnuts, and a cranberry-honey glaze to create the same sweet-savoury contrast.

Every bite gives you something different: naturally sweet roasted vegetables, creamy salty feta, crunchy walnuts, and bright cranberry. It’s elegant enough for a holiday table but comforting enough for a cosy family dinner.

Ingredients

For the Roasted Vegetable Layers

2 medium sweet potatoes, peeled and thinly sliced
2 cups butternut squash, thinly sliced or cut into very thin pieces
2 large carrots, peeled and thinly sliced
2 tablespoons extra-virgin olive oil
½ teaspoon dried thyme
½ teaspoon garlic powder
½ teaspoon salt
¼ teaspoon freshly ground black pepper

For the Creamy Feta Layer

1 cup crumbled feta cheese
½ cup plain Greek yogurt
1 tablespoon extra-virgin olive oil
1 tablespoon fresh lemon juice
1 garlic clove, minced
½ teaspoon dried oregano
¼ teaspoon black pepper

For the Topping

½ cup shredded mozzarella cheese
½ cup walnuts, roughly chopped
1 teaspoon fresh thyme leaves
2 tablespoons crumbled feta, optional

For the Cranberry-Honey Drizzle

½ cup 100% cranberry juice
2 tablespoons honey
1 tablespoon balsamic vinegar
1 teaspoon Dijon mustard
½ teaspoon fresh thyme leaves
Pinch of salt

The combination of cranberry, honey, and balsamic provides the sweet-tart glaze that complements the roasted vegetables and feta.

Instructions

1. Preheat the Oven

Preheat your oven to 400°F (200°C).

Lightly grease a 9×13-inch baking dish with olive oil.

Set aside.

2. Prepare the Vegetables

Peel the sweet potatoes and carrots.

Using a sharp knife or mandoline, slice the sweet potatoes and carrots into thin, even pieces.

Cut the butternut squash into thin slices or very thin pieces.

Try to keep the vegetables approximately the same thickness so they cook evenly.

Place everything into a large bowl.

Add:

Olive oil
Dried thyme
Garlic powder
Salt
Black pepper

Toss gently until all the vegetables are coated.

3. Roast the Vegetables

Arrange the vegetables in a single layer on one or two large baking sheets.

Avoid overcrowding the pans. If the vegetables are piled on top of one another, they’ll steam rather than roast.

Roast for approximately 15–20 minutes, turning the vegetables halfway through.

They should become slightly tender and develop a little colour, but they should still be firm enough to handle and layer.

Don’t roast them until completely soft because they will cook again during the final bake.

4. Make the Creamy Feta Mixture

While the vegetables are roasting, prepare the feta layer.

Add the following to a bowl:

Crumbled feta
Greek yogurt
Olive oil
Lemon juice
Minced garlic
Oregano
Black pepper

Mix until creamy.

You can leave some small pieces of feta throughout the mixture for texture.

For an especially smooth filling, blend everything in a food processor for about 30 seconds.

5. Toast the Walnuts

Place the chopped walnuts in a dry skillet over medium-low heat.

Toast for approximately 3–5 minutes, stirring frequently.

They should become fragrant and lightly golden.

Remove them from the heat immediately once toasted.

Be careful because walnuts can burn quickly.

Toasting brings out their natural nutty flavour and gives the finished dish a much better crunch.

6. Make the Cranberry-Honey Drizzle

Add the cranberry juice, honey, balsamic vinegar, Dijon mustard, thyme, and a pinch of salt to a small saucepan.

Bring the mixture to a gentle simmer over medium-low heat.

Cook for approximately 5–7 minutes, stirring occasionally.

The mixture should reduce slightly and become glossy.

Remove from the heat and allow it to cool for a few minutes.

It will continue to thicken as it cools.

7. Begin Layering

Reduce the oven temperature to 375°F (190°C).

Spread a very thin layer of the feta mixture across the bottom of the prepared baking dish.

Arrange a layer of sweet potato slices over the feta.

Add a layer of butternut squash and carrots.

Spread some of the creamy feta mixture over the vegetables.

Sprinkle a small amount of toasted walnuts over the layer.

8. Continue Building the Layers

Repeat the process:

Vegetables → feta mixture → walnuts → vegetables

Continue until all of the vegetables and feta mixture have been used.

Try to keep the layers relatively even.

Finish with a beautiful layer of sweet potato slices on top.

This creates an attractive golden finish after baking.

9. Add the Cheese

Sprinkle the shredded mozzarella evenly over the top.

Add a few extra crumbled pieces of feta if desired.

Reserve a small amount of walnuts for finishing after baking.

10. Cover and Bake

Cover the baking dish loosely with aluminium foil.

Bake at 375°F (190°C) for approximately 25 minutes.

The foil helps the vegetables steam and become tender without the top browning too quickly.

11. Uncover and Finish Baking

Remove the foil.

Continue baking for another 15–20 minutes.

The cheese should be melted and lightly golden, while the vegetables should be completely tender.

If you want a more deeply browned top, place the dish under the broiler for 1–2 minutes at the end.

Watch it carefully so the walnuts and cheese don’t burn.

12. Rest the Lasagna

Remove the dish from the oven.

Let it rest for 10 minutes before slicing.

This is important because the layers need time to settle.

Resting also makes the dish easier to serve without everything sliding apart.

13. Finish With Cranberry-Honey Drizzle

Just before serving, drizzle the warm cranberry-honey sauce over each portion.

Sprinkle with the reserved toasted walnuts.

Finish with fresh thyme leaves and a little extra feta.

Serve warm.

Recipe Notes

Slice the vegetables evenly

Thin, uniform slices cook more consistently and make the finished lasagna easier to cut.

Don’t over-roast initially

The vegetables should be partially cooked before layering, not completely soft. They will finish cooking during the second bake.

Toast the walnuts

This small step makes a big difference. Toasted walnuts have a deeper flavour and provide a wonderful crunchy contrast to the soft vegetables.

Watch the salt

Feta can be quite salty, so taste the feta mixture before adding additional salt.

Let it rest

Don’t skip the 10-minute resting period. It helps the layers firm up and makes serving much easier.

Helpful Tips

Use a mandoline carefully: a mandoline creates beautiful, uniform slices, but always use the safety guard.

Keep the cranberry glaze balanced: If your cranberry juice is very tart, add another teaspoon of honey. If it’s too sweet, add a small splash of balsamic vinegar.

Don’t drown the lasagna in glaze: the cranberry drizzle is designed as a finishing sauce. A light drizzle lets the feta and roasted vegetables remain the stars.

Use block feta when possible: Feta sold in a block often has a creamier texture than pre-crumbled varieties.

Make it ahead: The lasagna can be assembled several hours ahead and refrigerated before baking.

Easy Variations

Add Spinach

Add a layer of sautéed spinach between the roasted vegetables and feta.

Make sure the spinach is squeezed well to remove excess moisture.

Add chickpeas.

For additional plant-based protein, add a thin layer of seasoned roasted chickpeas.

Use goat cheese.

Replace some or all of the feta with soft goat cheese for a creamier and slightly tangier flavour.

Change the Nuts

Pecans, almonds, or hazelnuts can replace the walnuts.

Make It Vegan

Use dairy-free feta and yoghurt alternatives, replace mozzarella with a plant-based cheese, and substitute maple syrup for honey.

Add Fresh Herbs

Fresh rosemary, sage, parsley, or thyme can be added between layers or sprinkled over the finished dish.

Make-Ahead Instructions

This is an excellent make-ahead dish.

You can roast the vegetables and prepare the feta mixture up to 1 day ahead.

Store the components separately in the refrigerator.

Alternatively, assemble the entire lasagna, cover tightly, and refrigerate for several hours.

Remove from the refrigerator about 20–30 minutes before baking if convenient, then bake until heated through and tender.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Keep the cranberry drizzle separately if possible.

Reheat individual portions in the microwave or in a covered oven-safe dish at 350°F (175°C) until heated through.

Freezing

The assembled dish can be frozen, although the texture of the vegetables and feta may become slightly softer after thawing.

For best results, freeze without the cranberry drizzle and walnuts.

Thaw overnight in the refrigerator and reheat until hot throughout.

Add fresh toasted walnuts and cranberry-honey drizzle immediately before serving.

Frequently Asked Questions

Is this a traditional lasagna?

No. It’s a creative vegetable-based interpretation of lasagna. Instead of traditional pasta sheets and meat sauce, the recipe uses layers of roasted vegetables, feta, walnuts, and a cranberry-honey finish.

Can I use regular lasagna noodles?

Yes, but the recipe will become more like a traditional vegetable lasagna. You may need additional sauce or moisture if using pasta sheets.

Can I make this without mozzarella?

Absolutely. You can use additional feta, Parmesan, goat cheese, or a dairy-free cheese alternative.

Can I use frozen butternut squash?

Yes, but thaw and drain it thoroughly first. Excess moisture can make the lasagna watery.

Can I use cranberry sauce instead of cranberry juice?

Yes. A smooth cranberry sauce or cranberry preserve can be warmed with honey and balsamic vinegar to create a thicker glaze.

Can I make it without honey?

Yes. Use maple syrup for a vegan alternative, or reduce the sweetener if you prefer a more savoury dish.

Can I skip the walnuts?

Definitely. The walnuts provide crunch but aren’t essential. Pecans, pumpkin seeds, or sunflower seeds are good alternatives.

Why does my lasagna fall apart?

The vegetables may contain too much moisture, or the dish may not have rested long enough. Roast the vegetables properly and allow the finished lasagna to rest for at least 10 minutes before slicing.

Can I serve it as a side dish?

Yes. It works beautifully as a vegetarian main course or as a side dish alongside roasted chicken, turkey, or fish.

What goes well with it?

Serve with a simple green salad, roasted Brussels sprouts, steamed green beans, or a lemony arugula salad.

Serving Suggestions

For a beautiful presentation, place one slice on each plate and drizzle the cranberry-honey glaze over the top.

Add toasted walnuts, fresh thyme, and a small crumble of feta.

A simple green salad dressed with lemon and olive oil provides a refreshing contrast to the sweet roasted vegetables.

For a holiday meal, this dish pairs especially well with roasted poultry, although it is hearty enough to stand alone as a vegetarian centrepiece.

Final Thoughts

This Layered Sweet Potato, Butternut Squash & Carrot Lasagna with Feta, Walnuts & Cranberry-Honey Drizzle turns simple seasonal vegetables into a spectacular centrepiece.
