Top Reasons To Make It
This lasagna is more than just a meal; it’s a solution. It’s a fantastic make-ahead option, so you can assemble it a day early and simply pop it in the oven when guests arrive. It’s also naturally vegetarian, pleasing a wide range of holiday dinner guests. But the best part? The combination of sweet, nutty squash and earthy, aromatic sage just tastes like the holidays. It’s a flavor pairing that feels so, so right this time of year.
Ingredients
- 1 medium butternut squash (about 3 lbs), peeled, seeded, and cubed: The sweet, hearty star of the show.
- 2 tbsp olive oil: For roasting the squash to caramelized perfection.
- 1 tbsp maple syrup: Adds a subtle sweetness that complements the squash.
- 9-12 no-boil lasagna noodles: Such a time-saver for busy cooks.
- 4 tbsp butter: The rich base for our sage sauce.
- 20-25 fresh sage leaves: For that quintessential, cozy holiday aroma and flavor.
- 1/4 cup all-purpose flour: To thicken our creamy sauce.
- 3 1/2 cups whole milk: Creates a luxuriously smooth béchamel.
- 1/8 tsp ground nutmeg: A warm spice that pairs beautifully with squash.
- 1 1/2 cups shredded whole-milk mozzarella cheese: For that classic, stretchy, golden top.
- 1 cup grated Parmesan cheese: Adds a salty, nutty depth to every layer.
- Salt and black pepper: To taste, for bringing all the flavors together.
Instructions
- Preheat your oven to 400°F (200°C). Toss the cubed butternut squash with olive oil, maple syrup, and a pinch of salt on a large baking sheet. Roast for 25-30 minutes, stirring once, until the squash is tender and the edges are caramelized. Let it cool slightly, then mash with a fork until you have a rustic puree.
- While the squash roasts, make the sage béchamel. Melt the butter in a medium saucepan over medium heat. Once foamy, add the sage leaves and fry for about 60 seconds until fragrant and crisp. Remove the sage leaves to a paper towel-lined plate—they’re your garnish!
- Whisk the flour into the butter in the pan and cook for 1 minute. Gradually whisk in the milk until the mixture is smooth. Bring to a gentle simmer, whisking constantly, until the sauce thickens enough to coat the back of a spoon, about 5-7 minutes. Stir in the nutmeg and season generously with salt and pepper. Remove from heat.
- Reduce oven temperature to 375°F (190°C). To assemble, spread about 1/2 cup of the sage béchamel in the bottom of a 9×13 inch baking dish. Arrange a layer of noodles over the sauce. Spread half of the mashed squash over the noodles, followed by 1/2 cup of the béchamel, and a sprinkling of both cheeses. Repeat the layers (noodles, remaining squash, 1/2 cup béchamel, cheese). Top with a final layer of noodles, the remaining béchamel, and the rest of the cheese.
- Cover the dish with foil and bake for 25 minutes. Uncover and bake for another 15-20 minutes, until the top is bubbly and beautifully browned. Let the lasagna rest for at least 15 minutes before slicing. This patience is key for clean slices! Garnish with the crispy sage leaves.
Variations & Substitutions
Feel free to make this dish your own! If you’re short on time, frozen butternut squash puree can work in a pinch—just be sure to thaw and drain it well. For a gluten-free version, use your favorite gluten-free noodles and a 1:1 gluten-free flour blend. To add a bit of protein, a layer of sautéed spinach or some crumbled smoked turkey sausage would be lovely. And honestly, if you’re not a fan of sage, fresh thyme would be a wonderful herbal substitute.
Serving Ideas & Pairings
This lasagna is a complete meal in itself, but it plays wonderfully with others on your Christmas dinner table. For a starter, a simple arugula salad with a bright lemon vinaigrette cuts through the richness beautifully. It also makes a fantastic addition to a holiday charcuterie board spread, served alongside other festive Christmas dinner dishes. For a drink pairing, a crisp, non-alcoholic sparkling apple cider complements the squash’s sweetness perfectly.
Storage & Reheating
Leftovers? So good. Cool completely, then store covered in the refrigerator for up to 4 days. You can also freeze the baked lasagna for up to 3 months; just wrap it tightly. To reheat, thaw overnight in the fridge if frozen. Cover with foil and warm in a 350°F (175°C) oven for 20-30 minutes, until heated through. For a single serving, the microwave works just fine, though the oven will give you that crisp top again.
Pro Tips For Perfect Lasagna
- Let your lasagna rest after baking. I know it’s hard to wait, but it allows the layers to set for neater slices.
- Don’t skip crisping the sage leaves! They add a fantastic texture and concentrated flavor.
- Use a sharp knife to cut through the layers cleanly.
- No-boil noodles are your friend here—they save a step and work perfectly.
- For an extra festive touch, use a cookie cutter to cut squash slices into little holiday shapes before roasting.
- Taste your béchamel sauce before assembling and season it well. It makes all the difference!
