There are no limits to how many times you can safely reheat leftover home-cooked meals.
After each reheating, leftovers will be safe in the fridge for an additional three to four days. Because the quality decreases each time food is reheated, it is best to reheat only the amount needed. Cooked foods that cannot be used within four days should be frozen for longer, safe storage.
If food has been hygienically prepared, cooled quickly after cooking (or reheating) and stored cold, reheating more than once should not increase the risk of illness. But prolonged storage and repeated reheating will affect the taste, texture, and sometimes the nutritional quality of foods.
Leftovers can be kept for 3 to 4 days in the refrigerator. After that, the risk of food poisoning goes up. If you don't think you'll be able to eat leftovers within four days, freeze them right away. Frozen leftovers will stay safe for a long time.

In terms of food safety, however, so long as you reheat the food at the correct temperature and for the correct duration of time, it can in fact be safely reheated multiple times.

Technically, you can reheat lasagna multiple times so long as you bring it up to an internal temperature of 165° each time. This temperature kills most bacteria that might be present in your leftovers. That said, the quality degrades with each reheat, so we suggest reheating lasagna one time only.
Reheat Leftovers Safely
When reheating leftovers, be sure they reach 165° F as measured with a food thermometer. Reheat sauces, soups and gravies by bringing them to a rolling boil. Cover leftovers to reheat. This retains moisture and ensures that food will heat all the way through.
