How long should you marinate pork?
We suggest marinating pork for anywhere from 30 minutes to 12 hours. The longer you marinate it, the juicier and more flavorful your pork will be.
Can you marinate pork tenderloin too long?
In some cases, you can marinate pork tenderloin for too long. If it contains an acid like citrus or vinegar, we suggest only marinating for 30 minutes to 4 hours. This pork tenderloin marinade recipe, however, does not contain either of those.
How do you tenderize pork tenderloin?
The best way to tenderize pork tenderloin is with salt. You can do this by sprinkling the meat with coarse sea salt and let sit for around an hour.
Should pork tenderloin be cooked slow or fast?
It all depends on what cook-method you are using, but since pork tenderloin is a lean cut of meat, we suggest low and slow or hot and fast.
Freeze your pork tenderloin directly in the marinade so that you can thaw it and make it anytime. We suggest using a gallon-size plastic bag.
- Transfer the marinade and the pork tenderloin into the gallon-size bag.
- Remove as much air as possible and seal.
- Write Pork Tenderloin on the front of the bag and freeze for up to 3 months.
When you’re ready to cook it, let it thaw completely and then use your favorite cook-method.
