It is not safe to use the slow cooker to thaw or cook frozen meats.
I used to cook frozen roast in there regularly. Done to perfection in 10 hours.
My sister puts a frozen meatloaf in hers, a couple carrots under it to keep it off the bottom. Says it’s done perfectly in about 10 hours. I have not tired this, though.
the newer pots cook at a higher temp i think. i have been cooking frozen meats in a crock pot for 10 years or better. never had any problems.
I agree. We cook frozen meats all the time. Maybe that was a remark matched to the recipe.
