What to Serve Italian Vegetarian Lasagna With

• Salads – A peppery arugula salad with lemon vinaigrette, or a chilled cucumber salad for contrast.
• Bread – Whole-grain garlic bread brushed with olive oil and fresh herbs.

Top Tips for Perfecting

Roast, Don’t Sauté

Roasting vegetables at high heat caramelizes them and prevents excess water from seeping into the lasagna. This keeps your layers structured and the texture just right.

Rest Before Serving

Letting your lasagna cool for at least 20 minutes after baking allows the layers to set, making for cleaner slices.

Choose the Right Noodles

Regular boiled noodles yield a more tender bite than no-boil. If you prefer no-boil, increase baking time and add extra sauce for moisture.

Season Each Layer

Lightly season the spinach, ricotta, and vegetables individually so every bite is flavorful. This approach is similar to how you’d season each component in a layered dish like Stanley Tucci’s zucchini pasta.

Storing and Reheating Tips

Refrigeration

Cool completely, then store slices in an airtight container in the fridge for up to 4 days.

Freezing

Wrap individual portions tightly in foil or freezer-safe wrap, then place in a sealed container. Freeze for up to 3 months for easy future meals.

Reheating

For best results, reheat in the oven at 350°F until warmed through. If using a microwave, heat in short bursts and cover to keep the cheese from drying out.
