You can use a hand held mixer with the dough hooks connected, however for a batch of this length the use of a KitchenAid with the paddle attachment works better.

Don’t skip pre-baking the meatballs

I comprehend it’s tempting to throw the whole lot into the dish at once and cook dinner it that manner for comfort, but it’s genuinely necessary to present the meatballs 15 minutes inside the oven by way of themselves.

Otherwise they’re not very company and could collapse and collapse into the sauce.

See, that’s any other motive to pre-bake the meatballs. The spinach, irrespective of how nicely you squeeze it, will deliver off water as it chefs.

You need to drain most of the liquid that oozed out of the meatballs as they baked, otherwise the sauce will turn out to be as soup.

I want cheese on pinnacle if a casserole to be melty and bubbly, no longer burnt to a crisp.

That’s why I upload it best for the last three-four minutes of baking. That way it’s excellent and creamy.
