• 1/2 cup olive oil, less as needed

• 1/2 teaspoon dried thyme

For the Phyllo Layers:

• 10 sheets phyllo pastry
• Olive oil, for brushing

For the Cheese Topping:

• 5 ounces Gruyere cheese, to taste

Equipment Needed

To bring this delightful lasagna to life, you’ll want a few essential tools:

• Large baking sheets for roasting vegetables.
• A frying pan for sautéing mushrooms.
• A 9-by-12-inch baking dish.
• A pastry brush for applying olive oil to the phyllo.
• Aluminum foil for covering the lasagna during baking.

Instructions

The beauty of this lasagna lies in its layers, each contributing a unique texture and flavor. We begin by coaxing the deepest flavors from our vegetables through roasting and sautéing.

1. Preheat Oven and Prepare Vegetables: Begin by preheating your oven to 375 degrees Fahrenheit (190 degrees Celsius). In a large bowl, combine the sliced red bell peppers and the sliced yellow onion. Toss them with 1 tablespoon of olive oil, and season generously with salt and pepper to your liking. Spread these vegetables in an even layer on a baking sheet.

2. Roast Peppers and Onions: Place the baking sheet in the preheated oven and roast for about 30 minutes. You’re looking for the peppers and onions to become soft and for their edges to achieve a slight char, indicating beautiful caramelization. Once roasted, remove them from the oven and set aside.

3. Sauté Mushrooms: While the peppers and onions are roasting, prepare the portabella mushrooms. Clean them thoroughly and slice them into 1/4-inch strips. Heat 1 tablespoon of olive oil in a frying pan over medium heat. Add the sliced mushrooms and sauté them until they are soft. Remove from the heat and set aside with the roasted vegetables.

4. Prepare the Baking Dish: Lightly grease a 9-by-12-inch pan with olive oil. This will prevent the phyllo from sticking and ensure a beautiful golden crust.

5. Build the Phyllo Base: Take one sheet of phyllo pastry and carefully place it on the bottom of the prepared baking dish. Using your pastry brush, lightly dip into the remaining 1/4 cup of olive oil (you may need a bit more or less depending on your brush and dish size) and brush the phyllo sheet lightly. Repeat this process with four more sheets of phyllo, ensuring each layer is brushed with olive oil. This creates a sturdy, yet delicate, base for your lasagna.

6. Assemble the Vegetable Filling: In a separate bowl, combine the roasted peppers and onions, the sautéed mushrooms, and the baby spinach. Stir everything together well to ensure the ingredients are evenly distributed.

7. Layer the Filling and Herbs: Spread this vegetable mixture in an even layer over the prepared phyllo base in the baking dish. Sprinkle all of the dried thyme evenly over the vegetable layer. Next, sprinkle all of the Gruyere cheese over the thyme and vegetables.

8. Continue with Phyllo Layers: Take another sheet of phyllo pastry and place it over the filling. Brush this sheet lightly with olive oil. Continue this process, layering and brushing with olive oil, until all 10 sheets of phyllo pastry have been used. Aim for a relatively even distribution of oil on each layer.

9. First Bake (Covered): Once all the phyllo layers are in place, cover the pan securely with aluminum foil. Place the covered lasagna in the preheated 375°F (190°C) oven and bake for 20 minutes. This initial covered bake allows the vegetables to meld and the phyllo to steam slightly, ensuring a tender interior.

10. Second Bake (Uncovered): After 20 minutes, carefully remove the foil. Return the lasagna to the oven and bake for an additional 3 to 4 minutes, uncovered. The goal here is to achieve a very lightly browned and slightly crisped top layer of phyllo. Watch this step very carefully, as phyllo browns extremely quickly and can go from golden to burnt in mere moments.

11. Rest Before Serving: Once the lasagna is out of the oven, allow it to rest for about 5 minutes before slicing and serving. This short resting period allows the layers to settle and makes for cleaner cuts.

Expert Tips & Tricks

• Phyllo Handling: Phyllo pastry can be notoriously fickle. Always keep the unused sheets covered with a damp (not wet!) kitchen towel to prevent them from drying out. Work efficiently once you start layering.
• Vegetable Moisture: Ensure your roasted vegetables aren’t excessively wet before layering. If they seem very juicy, you can gently drain off any excess liquid to prevent the phyllo from becoming soggy.
• Cheese Adjustment: The recipe calls for Gruyere cheese, which offers a wonderful nutty flavor. However, feel free to adjust the amount “to taste.” If you’re not a huge cheese lover, you can use less. For a more pronounced flavor, you might even consider a blend of Gruyere and Parmesan.
• Even Browning: If you find your oven has hot spots and one side of the lasagna browns faster than the other, you can rotate the pan halfway through the uncovered baking time.

Serving & Storage Suggestions

This Roasted Vegetable-Phyllo Lasagna is a showstopper on its own, but it pairs beautifully with a simple side salad dressed with a light vinaigrette. The crispness of the salad will further complement the textures of the lasagna.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat individual portions gently in a toaster oven or a conventional oven at around 350°F (175°C) until warmed through. This helps to revive the crispness of the phyllo layers. While it’s best enjoyed fresh, it can also be frozen. Wrap individual portions tightly in plastic wrap and then in foil, and freeze for up to 1 month. Thaw in the refrigerator overnight before reheating as described above.

Variations & Substitutions

While this recipe is a delightful vegetarian option, here are a few ways to adapt it:

• Vegan Option: To make this recipe vegan, omit the Gruyere cheese. You can substitute it with a generous sprinkle of nutritional yeast for a cheesy flavor, or a vegan shredded cheese alternative. For the phyllo brushing, use olive oil as directed.
• Seasonal Vegetables: Feel free to incorporate other seasonal vegetables that roast well. Zucchini, eggplant, or even chunks of butternut squash (roasted separately until tender) can add wonderful dimensions.
• Herb Variations: While thyme is classic with roasted vegetables, consider adding a pinch of dried rosemary or oregano for a different aromatic profile. Fresh herbs can also be stirred into the vegetable mixture before layering, but be mindful that they might release more moisture.
• Spicy Kick: For those who enjoy a touch of heat, add a pinch of red pepper flakes to the vegetable mixture before roasting.

FAQs (Frequently Asked Questions)

Q: Why is my phyllo pastry tough instead of crispy?
A: Ensure you are brushing each layer generously with olive oil. Insufficient oil will prevent the phyllo from crisping properly. Also, make sure not to overbake it.

Q: Can I use pre-sliced vegetables to save time?
A: While pre-sliced vegetables might seem convenient, slicing them yourself allows you to control the thickness, which is important for even roasting and sautéing.

Q: My lasagna seems a bit dry, what did I do wrong?
A: Ensure that your roasted vegetables were not drained of all their natural moisture, and that you used enough olive oil for brushing the phyllo layers.

Q: Is it possible to make this ahead of time?
A: You can roast the vegetables and sauté the mushrooms a day in advance and store them in the refrigerator. Assemble the lasagna just before baking for the best results with the phyllo.

Q: What kind of pan is best for this recipe?
A: A standard 9×12 inch baking dish is ideal. A shallow oven-safe skillet would also work if you have one of the right dimensions.
