Recipe FAQs

Can I use chickpea pasta instead of regular pasta?

Yes, chickpea pasta works well and adds extra plant-based protein while maintaining a firm texture after baking.

How do I prevent the pasta from overcooking?

Cook the pasta until just al dente, as it will continue cooking in the oven, ensuring it remains firm and not mushy.

What can I use as a vegetarian protein alternative?

Replacing tuna with drained chickpeas or extra vegetables makes a delicious vegetarian version without losing flavor or texture.

Is it possible to make this dairy-free?

Yes, substitute milk and cheese with plant-based alternatives to keep the creamy texture and rich flavor intact.

How can I make the topping extra crispy?

Combine breadcrumbs with grated Parmesan or cheddar and sprinkle evenly over the bake before cooking for a golden crunchy finish.
