Can I make this ahead of time?

Yes, and truth be told, it might taste even better the next day. Slow-cooked meals settle and sing after a night in the fridge. Reheat gently and enjoy the deeper flavors.

Can I use spicy sausage?

Absolutely. Swap in hot Italian sausage if you like heat. If you are feeding children, you can mix hot and mild to find a happy medium.

Is there a vegetarian option?

Yes. Replace the sausage with a plant-based crumbled "sausage" or a mix of mushrooms and lentils for a similar texture. Boost the seasoning so it has that savory backbone.

How long does it keep in the freezer?

Properly stored, portions can last up to three months. Thaw overnight in the refrigerator for best results and reheat until steaming hot.

Can I use different cheeses?

Mozzarella melts beautifully, but a combination of mozzarella and provolone or a sharp cheddar adds character. Sprinkle a little Parmesan for a nutty finish. These answers come from years of serving this dish at Sunday tables and holiday gatherings. I keep my guidance simple and practical so you can feel confident in your kitchen decisions.
