Recipe FAQs

How do I achieve the best texture for the tomato layer?

Simmer the crushed tomatoes with herbs gently to concentrate flavors while maintaining a smooth consistency before adding cream to enhance richness.

What type of bread works best for the grilled cheese layer?

Sourdough or country-style bread provides a sturdy base that crisps well and holds the cheese without becoming soggy.

Can I prepare this casserole ahead of time?

Yes, assemble and refrigerate it before baking. Bring to room temperature and bake as directed to ensure even cooking.

What cheeses create the best melt and flavor?

Sharp cheddar offers flavor depth, while mozzarella contributes smooth meltiness and creaminess for the perfect layered taste.

How can I add a spicy kick to this dish?

Incorporate a pinch of red pepper flakes into the tomato base during simmering to balance creaminess with subtle heat.
