Lasagna/baked pasta is always a hit. Easy to portion, uses lots of what you already have in house. Tubular pasta shapes are popular these days: penne, ziti, mastaccoli, cavatappi. Easy to do stovetop cheese sauces, marainara, signature meatsauce, cream/cheese based “alfredo” type. Sausage, meatballs and chicken become easy add-ons.
I even made some heads turn with an aglio e olio (garlic & oil with parm).
