In another video Ramirez said the chain's soups are also frozen, but it's not against the norm.
"Most stores have frozen things," she said, adding that people should still go to Panera and that she still eats the soups and mac and cheese.
CNN reported another video showed the employee crying as she said she had been fired.
A spokesperson for Panera wouldn't comment on the woman's employment status but told CNN the food is shipped to restaurants frozen to meet cleanliness standards.
"Mac and cheese is made off-site with our proprietary recipe developed by our chefs and using our sourced ingredients that meet our standards for our clean menu offerings," the spokesperson said.
"There was no wrongful termination," Ramirez said on Twitter. "Having such long nails and my phone out is a risk to food safety and health regulations. Everything was completely justified. I made a mistake and i've learned from it. I will always love panera and their food."
