This first time I made this Marinated Pork Loin was when my parents first met my fiancé’s parents. I was super nervous. Probably because I thought that by the end of the meal, they would have decided that Andrew and I shouldn’t get married!
Luckily, over loads of good food (and some Colombian charm ;)) they got along great. My soon-to-be father-in-law (in 3 days!!! woo!) made this delicious marinated pork loin, and I am pretty sure I ate about 3 pounds worth. It was AMAZING.
The best part? It’s only two ingredients! And he shared his special grilling secret with me – just keep the temp low and cook slow! Enjoy!
Recipe Ingredient Notes
To make our marinated pork loin recipe, you only need two ingredients:
- Pork loin roast: approximately 4 pounds;
- Italian salad dressing: 1 bottle (16 ounces).
Equipment Needed
For this recipe, you only need a few simple kitchen tools. We recommend using the following equipment:
How to Make Our Marinated Pork Loin
- The night before, place the pork loin in an airtight container (or a ziploc bag) and cover completely with ¾ of the bottle of Italian dressing. Set aside the remaining dressing for cooking. Place pork loin in the fridge and let marinate overnight.
- When you’re ready to cook it, set your grill to the lowest heat setting (the trick is to cook it low and slow).
- Set the whole pork loin directly on the grill and cook each side for a couple of minutes (I did about 5 minutes a side). Then cut the loin into 1″ slices. Baste each slice with the remaining Italian dressing.
- You should flip the slices every three minutes or so, basting with marinade each time you do.
- Grill until the internal temperature of each 1″ slice of pork reaches between 145-160℉ (depending on how you like your pork).
- Total grill time was about 30 minutes, but it will vary depending on the heat of your grill.

Oh, yum! Looks fab! But, now let’s get to the good stuff: Good luck on the wedding! WOOT, WOOT!!!
Why would you slice the roast into chops on the grill?
Why cut the meat then grill? What is the purpose of this?
