Can I make these ahead of time?
Yes. Assemble the skewers, refrigerate unbaked for up to 24 hours, then bake directly from the fridge, adding 2–3 minutes to baking time.
What's the best way to keep the cheese inside the meatballs?
Wrap the ground meat completely around each mozzarella cube and seal the seams well. Chill the meatballs for 15 minutes before threading onto skewers to help them hold their shape.
Can I use a different type of cheese?
Yes. Provolone, fontina, or white cheddar work well. Use cheese that melts smoothly and won't leak out during baking.
What skewers should I use?
Metal skewers or soaked wooden skewers both work. Metal skewers conduct heat evenly; soak wooden ones for 30 minutes to prevent burning.
How do I know when they're done?
Bake until the pizza dough is golden brown and an instant-read thermometer inserted into a meatball (not the cheese) reads 160°F.
