Tips & Substitutions

To enhance the flavor of the casserole, consider adding garlic or a sprinkle of red pepper flakes for a bit of heat. If you don't have Parmesan cheese, any hard cheese like Pecorino or even nutritional yeast for a vegan alternative can work well. For a heartier dish, feel free to incorporate cooked grains such as quinoa or rice as a base, similar to a Ratatouille(Mediterranean Vegetable Stew).

You can also mix in some cooked pasta for a heartier vegetarian dish, or explore other Mediterranean recipes that complement these flavors.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, microwave in 30-second intervals until warmed through, or place in the oven at 350°F (175°C) for about 15 minutes. Avoid overcooking to keep the vegetables from becoming mushy.

Can I use frozen vegetables instead of fresh ones?

If you’re out of basil or thyme, consider using Italian seasoning or oregano as a substitute. These herbs will provide a similar flavor profile, enhancing the dish without compromising its essence.
