The meal deal costs just £22 and includes a turkey breast joint, parsnips, sprouts, pork, sage and onion stuffing balls and an Irish Cream gateaux.
According to the Mail Online, the post was originally shared on the Extreme Couponing and Bargains UK group on Facebook by Robyn Greenfield who shared a snap of the "fab deal".
But she was forced to edit the post after some reportedly blasted that eating the frozen meal deal was for "lazy people".
She said: "For all those being judgemental about frozen food, scroll past then. Why people got to be so rude? It's Christmas and some families can't afford a lot. I personally cook all fresh food on Christmas.
"But for some family's this may be a bargain to feed 6 people. Did no one ever teach some of you if you have nothing nice to say don't say anything at all, simple?"
However, the post drew widespread praise from others – who hailed it as "amazing" and "brilliant" for those who want to spend more of the day with family rather than cooking.
One said: "I always buy frozen, takes less time to prepare therefore I can spend more time with my kids on Christmas morning than in the kitchen."
Another added: "Some of us would rather spend time with our families and have a nice quick Christmas lunch, nothing wrong with this at all."
"Perfect! May mean that some families that might not be able to afford a lavish Christmas dinner now can," another said.
The bargain Christmas dinner meal includes a boneless turkey breast joint, sausage and bacon rolls, honey roast parsnips, roast potatoes, 20 pork, sage and onion stuffing balls, sprouts and Iceland's Irish Cream Gateau.
