Here’s a list of major U.S. chain restaurants known for using pre-manufactured, pre-packaged, or heavily processed food components — meaning much of their menu is reheated, assembled, or finished on-site rather than cooked from scratch.
Fast Food & Quick Service
These chains rely almost entirely on industrially pre-made food due to volume, speed, and consistency requirements:
-
McDonald’s – Burgers, nuggets, and even eggs are partially pre-cooked and frozen.
-
Burger King – Uses flame-broiled preformed patties and pre-fried sides.
-
Wendy’s – Burgers are fresh but sauces, chili, and baked potatoes use centralized prep.
-
Taco Bell – Meats, beans, and sauces are shipped pre-cooked and reheated in bags.
-
KFC – Chicken is par-cooked and breaded using standardized mixes; sides are from mixes or frozen.
-
Subway – Meats, breads, and cookies come pre-frozen or pre-sliced.
-
Pizza Hut / Domino’s / Papa John’s – Dough and sauces are industrially prepared; toppings pre-packaged.
-
Arby’s – Roast beef and other meats are pre-cooked and reheated on-site.
-
Panda Express – Many items (especially sauces and proteins) are made in central kitchens.
-
Jack in the Box / Carl’s Jr. / Hardee’s – Use pre-formed, frozen, and pre-seasoned items.
Casual Dining Chains
Even sit-down chains use central commissaries or industrial suppliers for sauces, sides, desserts, and proteins:
-
Applebee’s – Most sauces, soups, and proteins arrive pre-cooked or frozen.
