Can I prepare this pumpkin lasagna ahead of time?

Absolutely! You can assemble the lasagna a day in advance and keep it refrigerated. Just cover it tightly with plastic wrap or aluminum foil. When ready to eat, bake it according to the recipe instructions, adding a few extra minutes if it’s coming straight from the fridge.

Why is my lasagna watery?

A watery lasagna often results from excess moisture in the vegetables and sauce. To avoid this, try the following tips:

  • Thinly slice vegetables like zucchini and mushrooms to reduce moisture content.
  • Pre-cook the vegetables, pan-frying them to evaporate excess moisture, and be sure to drain any water left in the pan.
  • Ensure your béchamel sauce is thick and creamy; a watery sauce can contribute to a soggy lasagna.
  • Allow the lasagna to rest for at least 5-10 minutes after cooking in the oven. This helps the layers settle and the moisture to redistribute, making it easier to slice and serve.

Roasted Pumpkin Puree

  • 600 g cubed pumpkin, butternut or Jap, (skin and seeds removed)
  • 1 Tbsp extra virgin olive oil
  • 1 tsp garlic powder
  • 1/2 tsp salt

Vegetable Mixture

  • 1-3 Tbsp extra virgin olive oil, extra if needed
  • 1 large red or brown onion, peeled and roughly chopped
  • 2 large cloves garlic, peeled and minced
  • 2 large carrots, sliced into rounds
  • 2 large zucchinis, trimmed and thinly sliced into rounds
  • 1 (200g / 7 oz.) sliced white mushrooms
  • 1 heaping cup broccoli florets
  • 1 cup frozen peas
  • Salt and pepper, to taste

Pumpkin Béchamel

  • 113 g (1 stick) unsalted butter
  • 1/2 cup all-purpose flour
  • 3 cups whole milk
  • 1/2 tsp ground nutmeg
  • Salt and pepper, to taste
  • 1 cup (280g / 10 oz.) roasted pumpkin puree
  • 1 cup shredded sharp cheddar cheese

Instructions
 

Roasted Pumpkin Puree

  • Preheat Oven: Preheat your oven to 400°F (200ºC). Set aside a medium size sheet pan.
  • Prep Pumpkin: Cut the pumpkin into medium-size cubes after removing the skin and seeds, ensuring the pieces are of uniform size for even roasting.
  • Season: In a large bowl, toss the cubed pumpkin with the olive oil, garlic powder and salt until well coated.
  • Arrange: Spread the pumpkin in a single layer on the sheet pan.
  • Roast: Roast for 30 minutes, or until the pumpkin is tender and lightly caramelized on the edges. Stir halfway through to ensure even cooking. Remove from the oven.
  • Puree: Transfer the pumpkin to a bowl and mash it using a potato masher or blend it in a food processor until smooth, it will have some chunks. You should end up with approximately 280g (about 1 cup) of mashed cooked pumpkin. Set aside. Keep your oven on at 400ºF (200ºC).


Vegetable Mixture

  • Prep Pan: Grease a 9×13 lasagna pan with butter and set it aside.
  • Sauté Onion and Garlic: Heat 1 Tbsp olive oil in a large skillet over medium-high heat. Add onion and sauté until translucent. Add minced garlic and cook for a further 1 minute, until fragrant.
  • Cook Carrots: Add sliced carrot and cook for 4 minutes or until the carrot has just started to soften.
  • Add Zucchini: Add sliced zucchini and cook until soft, about 4 minutes, adding more oil if needed to prevent sticking.
  • Stir in Mushrooms: Stir through mushrooms and allow to cook until softened and they begin to release their juices, about 5 minutes.
  • Add Broccoli, Peas and Season: Add broccoli and peas, and cook until broccoli is vibrant and just tender. Season with salt and pepper to taste.
  • Finish Vegetables: Once vegetables are tender/soft, turn off the heat and leave them in the pan while you prepare the white sauce.

Pumpkin Béchamel

  • Melt Butter: Melt butter in a medium-large skillet over low heat.
  • Add Flour: Once completely melted, increase the heat to medium-high, add the flour and whisk it through the butter while cooking for 1 minute.
  • Mix in Milk: After the 1 minute, gradually add the milk, half a cup at a time, whisking continuously after each addition until the mixture begins to thicken—this will happen quickly. Once all the milk is incorporated, increase the heat to medium-high and continue whisking constantly to prevent the sauce from boiling until it thickens.
  • Season Sauce: Add nutmeg and season with salt and pepper to taste, mix well.
  • Add Pumpkin Puree: Incorporate the roasted pumpkin puree, gently mixing it with a silicone spatula or wooden spoon. Continue stirring for a few minutes as the sauce thickens further. Once done, turn off the heat and set the sauce aside.

Assemble

  • First Layer: Lay one layer of lasagna sheets (4 sheets) in the bottom of the greased pan.
  • Add Vegetables: Pour half of the vegetable mixture over the sheets, spreading out evenly.
  • Layer White Sauce: Pour over one-third of the pumpkin sauce and spread it over the vegetables.
  • Repeat Layers: Lay another layer of lasagna sheets (4 sheets), spread over the remaining half of the vegetables, and pour and spread over the second-third of the pumpkin sauce.
  • Final Layer: Lay another layer of lasagna sheets (final 4 sheets), pour and spread over the remaining one-third of the sauce.
  • Top with Cheese: Sprinkle the shredded cheese over the sauce on top.
  • Bake: Bake for 35-40 minutes or until the top is golden and the filling is bubbling.
  • Rest: Remove from the oven and allow it to rest uncovered, for 5 minutes before serving. Enjoy!
