Notes

For extra flavor, add sun-dried tomatoes or swap spinach for kale. Pairs beautifully with a crisp green salad and garlic bread. For a vegan version, use plant-based cheeses and omit the egg.

Recipe FAQs

Can I substitute ziti with other pasta types?

Yes, penne or rigatoni work well as substitutes, holding sauces nicely without altering the dish's texture.

How can I make this dish vegan-friendly?

Replace the cheeses and egg with plant-based alternatives to maintain creaminess and texture suitable for vegan diets.

What is the best way to wilt spinach for this bake?

Sauté the spinach briefly with olive oil until just wilted to preserve its vibrant color and fresh flavor.

Can olives be omitted or replaced?

Olives add a briny contrast but can be skipped or replaced with sun-dried tomatoes for a different tangy note.

How do I achieve a golden cheese crust on top?

Bake uncovered for the last 10–15 minutes to allow the mozzarella and Parmesan to melt and brown beautifully.
