Andrea Laureano shared her recipe on the Slow Cooker Recipes & Tips Facebook page, explaining that the secret to perfectly juicy roast beef is chucking it in the slow cooker with a can of Coke, a tin of mushroom soup, and dry onion soup mix and then cooking it for 12 hours.
Laureano wrote that she'd tried around nine different recipes before getting it right, but that none compared to the Coke and soup method which has become her "go-to".
"Mix the soda and soup together [in the slow cooker]. Put the roast in [2-3lbs, well-marbled is best] then sprinkle the seasoning packet on top of the roast. I flip it halfway. The longer you can roast the better. I do 12 hours on high."
And you won't be able to get away with a low-sugar option, she warns - once she tried using Diet Coke and "it was disgusting".
Some Facebook users praised her genius, while others slammed the idea of simply pouring Coke and soup over a cut of beef.
