Prepare the pork loin
In order to easily stuff and roll the pork loin, you need to flatten this thick piece of meat. Horizontally slice down the middle of the loin without slicing all the way though. Go down the loin until the log is fully butterflied. Open it up like a book and lay if flat. Cover it with a piece of plastic wrap and pound it down until the final thickness is about 1/2 inch.
Saute the onions.
This is probably the longest part of prep work in this recipe. Slice up 4 yellow onions and throw them in a large saucepan with a stick of butter and cook over low heat. Mix occasionally to prevent onions from burning or sticking to the bottom of the pan. Once the onions are nice and soft add some beef stock to provide liquid for further sautéing. The broth also gives the onions that delicious french onion taste.
Dad’s Seasonings
Must have grillin seasonings!
Time to stuff and roll.
Season the butterflied pork with a garlic and herb seasoning of choice. I used a seasoning by Meat Church but honestly anything you have in the pantry will work just fine.
Next, add a generous layer of shredded Gruyere cheese because well it’s just delicious and some of it will ooze out while on the grill. Top the cheese with the sautéed onions leaving 1/2 cup for later use.
Time to roll this loin. Start from one end and slowly roll down to the other side making sure to keep in all the oniony goodness. To secure the roll, use 4-5 strips of butcher twine and tightly tie sections on the pork log.
Finally, season the entire outside of the stuffed pork loin with more garlic and herb seasoning and this baby is ready to hit the grill.
Time to grill the french onion pork loin.
Preheat the grill to 375 degrees and set for indirect heat. Place the pork loin onto a wire rack and place on the grill.
At around 135 degrees internal temperature, top off the grilled french onion pork loin with the remaining cheese and onions and cook for another 10-15 minutes.
Total grill time should be around 45 minutes or until the internal temperature of the pork reaches 145 degrees.
Let it rest for 10 minutes before slicing. Enjoy!
