Tasty Roast Vegetable Lasagne

The scent of roasting vegetables – sweet peppers caramelizing at the edges, garlic mellowing into a creamy sweetness – always takes me back to my grandmother’s kitchen. She had a knack for coaxing the best flavors out of the simplest ingredients, and her vegetable lasagne was legendary. Each layer was a testament to her love, a comforting hug in every bite. I remember being tasked with carefully layering the pasta, each sheet a canvas for her culinary artistry. Today, I carry on that tradition, adding my own little twists while still honoring the essence of her delicious creation.

Cheese grater

Instructions

Preheat the oven to 200°C (400°F).
Prepare the vegetables for roasting. Cut the red pepper into 2-inch chunks. Cut the tomatoes and onions into wedges. Slice the courgettes and leek into rings.
Place all the prepared vegetables into a large roasting dish. Peel the garlic cloves, smash them flat with the flat of a knife blade, and add them to the dish.
Drizzle 4 tablespoons of olive oil over the vegetables. Add plenty of salt and pepper. Mix well to ensure all the vegetables are coated in oil and seasoning.
Roast the vegetables in the preheated oven for about 30 minutes, or until they are softened and slightly caramelized. Turn them over occasionally to ensure even cooking.
While the vegetables are roasting, prepare the tomato sauce. Finely dice the onion and add it to a large frying pan with 4 tablespoons of olive oil. Gently cook the onion over medium heat until it starts to soften.
Add the crushed garlic to the pan with the onion and cook for another 2 minutes, until fragrant.
Stir in the tomato puree and then add the diced mushrooms. Mix thoroughly until everything is coated in the tomato puree. Let the mushrooms soften for a couple of minutes.
Add the tinned peeled tomatoes to the pan, mashing them up a little with a spoon. Stir in the dried basil, dried thyme, and dried oregano. Pour in the red wine.
Let the tomato sauce gently reduce in the pan for 10-15 minutes, or until very little juice remains. Season generously with black pepper (approximately 1 tablespoon) and some salt. Taste and adjust seasoning as needed.
While the tomato sauce is simmering, prepare the white sauce. Melt the butter in a large saucepan over a gentle heat.
Once the butter is completely melted, add the flour and stir well to combine, creating a roux. Heat for a minute or so more, cooking off the raw flour taste.
Gradually add the cream, a little at a time, making sure each addition is well combined before adding the next. Do the same with the milk.
Gently continue to heat the white sauce, stirring constantly, until it starts to thicken to your desired consistency. If the sauce becomes too thick, adjust the consistency by adding more milk. Season with a little white pepper.
Now it’s time to assemble the lasagne! Spoon half of the roasted vegetables into the bottom of a suitable lasagne dish.
Spread half of the tomato mixture evenly over the roasted vegetables.
Cover the tomato mixture with a layer of dried lasagne sheets, breaking them to fit if necessary.
Dot half of the cream cheese over the lasagne sheets, using a teaspoon to distribute it evenly.
Spoon half of the white sauce over the cream cheese layer.
Repeat layers: remaining roasted vegetables, tomato mixture, lasagne sheets, cream cheese, and white sauce.
Sprinkle the top of the lasagne generously with grated cheddar cheese and grated nutmeg.
Return the assembled lasagne to the oven and bake for approximately 20 minutes, or until the cheese is melted, bubbly, and golden brown, and a knife passes through the pasta with no resistance. If the top is browning too quickly, cover loosely with foil.
Let the lasagne rest for 10-15 minutes before slicing and serving.

Expert Tips & Tricks

Roast vegetables for deeper flavor: Roasting the vegetables brings out their natural sweetness and creates a richer, more complex flavor than simply sautéing them. Don’t be afraid to let them get slightly caramelized.
Make-ahead tip: The roasted vegetables and tomato sauce can be made a day in advance. Store them separately in the refrigerator until you’re ready to assemble the lasagne.
Cream Cheese Hack: If you’re short on time, you can skip dotting the cream cheese and simply mix it into the white sauce. This will create a richer, tangier sauce.
Preventing Soggy Lasagne: Ensure that the tomato sauce is well-reduced to prevent a soggy lasagne. If your vegetables release a lot of liquid during roasting, drain some of it off before layering.
Cheese Variety: Feel free to experiment with different cheeses! Gruyere, mozzarella, or even a smoked cheese can add interesting flavor dimensions.

Serving & Storage Suggestions

Serve the roast vegetable lasagne hot, straight from the oven, with a simple green salad and some crusty bread. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and bake in a preheated oven at 175°C (350°F) until heated through, or microwave individual portions. The assembled, unbaked lasagne can also be frozen for up to 2 months. Thaw completely in the refrigerator before baking as directed.

Variations & Substitutions

Gluten-Free: Use gluten-free lasagne sheets and ensure your flour is a gluten-free blend when making the white sauce.
Vegan: Substitute the butter with vegan butter, the cream and milk with plant-based alternatives like oat milk or cashew cream, and the cheddar and cream cheese with vegan versions.
Seasonal Vegetables: Adapt the recipe to use seasonal vegetables. In the fall, try adding butternut squash or pumpkin to the roasting pan. In the spring, asparagus or peas would be delicious additions.
Spicy Kick: Add a pinch of red pepper flakes to the tomato sauce for a subtle heat.
Herb Variations: Experiment with different herbs in the tomato sauce. Fresh herbs like rosemary or sage would also work well.

FAQs (Frequently Asked Questions)

Q: Can I use fresh lasagne sheets instead of dried?

A: Yes, fresh lasagne sheets can be used. You may need to adjust the baking time slightly, as fresh pasta cooks faster than dried.

Q: Can I use different types of vegetables for roasting?

A: Absolutely! Feel free to substitute the vegetables with your favorites or whatever you have on hand. Eggplant, bell peppers of different colors, and mushrooms all work well.

Q: Can I make this lasagne without red wine in the tomato sauce?

A: Yes, you can omit the red wine. Simply substitute it with an equal amount of vegetable broth or water. The wine adds depth of flavor, but the sauce will still be delicious without it.

Q: How do I prevent the top of the lasagne from burning?

A: If the top is browning too quickly, cover the lasagne loosely with aluminum foil during the last 10-15 minutes of baking.

Q: Can I freeze the leftover lasagne?

A: Yes, you can freeze leftover lasagne. Allow it to cool completely, then cut it into individual portions and wrap each portion tightly in plastic wrap and then in foil. Freeze for up to 2 months.
