How to Make Autumn Lasagne with Leek & Butternut Squash

Step 1: Prepare the squash and leeks

Start by peeling and dicing the butternut squash into even cubes. Toss with olive oil, salt, and pepper, then roast at 400°F (200°C) until tender and lightly caramelized, about 25-30 minutes. While the squash roasts, thinly slice the leeks and sauté them gently in olive oil with minced garlic until soft and fragrant. Set both aside to cool.

Step 2: Make the béchamel sauce

In a saucepan, melt butter over medium heat. Stir in flour to create a roux, cooking for a minute or two without browning. Gradually whisk in warm milk, stirring constantly to avoid lumps, until the sauce thickens and becomes smooth and creamy. Season with salt, pepper, and a hint of nutmeg for warmth. Remove from heat.

Step 3: Assemble the lasagne layers

In a baking dish, spread a thin layer of béchamel sauce. Add a layer of lasagne sheets, then roasted butternut squash, sautéed leeks, and a sprinkle of grated cheese. Repeat the layers, finishing with a generous layer of béchamel topped with extra cheese for a golden crust.

Step 4: Bake the lasagne

Cover the dish with foil and bake in a preheated oven at 375°F (190°C) for about 30 minutes. Remove the foil and bake for another 15 minutes or until the cheese on top is bubbling and golden brown. Let it rest for 10 minutes before serving for best results.

Pro Tips for Making Autumn Lasagne with Leek & Butternut Squash

• Even roasting: Cut the butternut squash into uniform pieces to ensure all cubes cook evenly and caramelize well.
• Don’t rush béchamel: Take your time whisking the sauce to avoid lumps and achieve a velvety texture.
• Layer thoughtfully: Distribute vegetables evenly to get a perfect balance in every bite.
• Rest before serving: Allow the lasagne to set after baking so slicing is neater and the flavors meld beautifully.
• Use fresh herbs: Stir fresh thyme or sage into the béchamel or sprinkle on top for added aroma and flavor complexity.

How to Serve Autumn Lasagne with Leek & Butternut Squash

Garnishes

Finish with fresh chopped parsley or sage leaves for a pop of color and fresh herbal brightness. A light drizzle of good-quality olive oil or a sprinkle of toasted pumpkin seeds can add a lovely textural contrast.

Side Dishes

Pair with a crisp green salad dressed in lemon vinaigrette to cut through the richness, or serve alongside roasted root vegetables for an extra cozy autumn meal. A warm crusty bread is always welcome to mop up any creamy sauce.

Creative Ways to Present

Serve individual portions in ramekins for a charming look, or layer the lasagne in a glass dish so guests can see the vibrant layers. Alternatively, accompany with a warming glass of spiced apple cider or a medium-bodied red wine to elevate the experience.

Make Ahead and Storage

Storing Leftovers

Store leftovers in an airtight container in the refrigerator for up to 3 days. The flavors often deepen overnight, making it an even more delicious next-day meal.

Freezing

Autumn Lasagne with Leek & Butternut Squash freezes wonderfully. Wrap tightly in foil or transfer to a freezer-safe container and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

Reheat individual portions in the microwave or warm the entire dish in the oven covered with foil at 350°F (175°C) until heated through, about 20-30 minutes. Remove the foil in the last 5 minutes to refresh the crispy cheese topping.

FAQs

Can I make this lasagne vegan?

Absolutely! Swap out dairy béchamel for a plant-based sauce using almond or oat milk and use vegan cheese options to keep it creamy without animal products.

Do I need to cook the lasagne sheets beforehand?

If you use no-boil or fresh lasagne sheets, there’s no need to pre-cook them. If using dried sheets, slightly boiling them helps prevent dryness in the finished dish.

Can I prepare this lasagne in advance?

Yes! It’s perfect for making ahead. Assemble the lasagne, cover tightly, and refrigerate for up to 24 hours before baking it fresh.

What cheese works best for this recipe?

Low-moisture mozzarella melts beautifully, but adding Parmesan or cheddar enhances flavor complexity. Choose cheeses you enjoy for best results.

Is this recipe gluten-free?

To make it gluten-free, use gluten-free lasagne sheets and substitute regular flour in the béchamel sauce with a gluten-free alternative like rice or chickpea flour.
