Recipe FAQ

Can I use chickpea pasta instead of regular pasta?

Yes, chickpea pasta works well and adds extra plant-based protein without altering the bake's texture significantly.

How do I know when the bake is ready?

The bake is done when the top is golden brown and the sauce is bubbling around the edges, usually after 20–25 minutes in the oven.

What cheese varieties work best for this dish?

Cheddar and mozzarella are classic choices for melting and flavor, while Parmesan adds a sharp, nutty topping when sprinkled on top.

Can I prepare this dish ahead of time?

Yes, assemble the bake and refrigerate it before baking. Allow extra baking time if baking from cold.

What adjustments are needed for a vegetarian version?

Replace tuna with canned chickpeas or extra vegetables like spinach or bell peppers for a plant-based alternative.
