FRENCH ONION STUFFED PORK LOIN

I don’t know how to convince you enough to make this French Onion Stuffed Pork Loin recipe. I thought about using all caps to get my point across, but I didn’t want you to think I was yelling. But, I really want to yell it from the mountaintops, ‘MAKE THIS RECIPE!’ It has to be one of the tastiest pork recipes I have ever tried! French onion flavor is perfect for the fall season and cooler temperatures, and it is beyond perfect for a pork loin.

FRENCH ONION STUFFED PORK LOIN RECIPE

In this French Onion Stuffed Pork Loin recipe, I used a center-cut pork loin, not a pork tenderloin. Although the names are very similar, the cuts of meat are actually quite different. Both cuts of meat are very lean and healthy, but the size and cooking times are quite a bit different. The center-cut pork loin is quite a bit larger than a pork tenderloin. For this recipe, I used a 3-pound pork loin.

Center-cut pork loin is one of the leanest cuts of meat, so be careful about choosing one. The redder the meat, the leaner it is, but also the tougher it is. I recommend choosing a pork loin with a more pinkish color with some white streaks. Don’t be fooled if you see a pork sirloin. That is a different cut of meat that is not as tender or lean as a pork loin or tenderloin. Who knew there were so many cuts of pork?!? I didn’t even begin to mention the ribs, pork shoulder, pork butt, ham, etc!

Onion Ingredients

  • Butter
  • Onions–I use yellow onions for a lot of my meat recipes since they add a lot of flavor without being too strong.
  • Beef broth

Pork Loin Ingredients

  • Pork loin–Remember to look for a center-cut pork loin, not a tenderloin for this recipe!
  • Olive oil–Extra virgin olive oil is best.
  • Salt
  • Pepper

Italian seasoning–You could also substitute 1/4 teaspoon of basil and thyme, with a 1/2 teaspoon of dried oregano, if you prefer.
Gruyere cheese–There are not many great substitutes for Gruyere cheese, so try to stick with it for this recipe. If you must find a replacement, look for Emmental, Jarlsberg, Beaufort, or comté cheese. (Stay away from American Swiss cheese if you can.)
Parsley–for garnish, but it is just as flavorful without it!

HOW TO MAKE FRENCH ONION STUFFED PORK LOIN

With the popularity of my Jalapeno Popper Pork Loin, I knew I had to make another stuffed pork loin, and I am so glad I did! The French onion flavors that are bursting from this recipe are amazing! (Are you starting to sense my excitement over this recipe)? It’s all about the onions and the cheese.

Preheat the oven to 450°F while you brown the onions. This will take about 20 minutes. Cook the onions in an oven-safe, large skillet. The pork loin will be going back in there. Be sure to keep the cooked onions warm by putting an aluminum tent over them while you prepare the pork loin. Before butterflying the loin, mix the oil, salt, pepper, and Italian seasoning in a bowl. This will be rubbed on both sides of the loin.

To butterfly the pork loin, use a sharp knife to make a horizontal cut about one-third of the way up from the bottom of the loin. Flip open the thicker, top flap (like opening a book). Then, take the knife and cut another horizontal line through the thicker part of the loin to open it up even more (like a trifold). You should now have a flat surface of meat that will hold the flavor of the French Onion Stuffed Pork Loin. Put a piece of plastic wrap over the laid out pork loin and pound it out to about a 1/3 inch thickness all the way around. The more even the loin is, the more evenly it will cook. Once the pork loin has been butterflied, rub both sides with the oil mixture.

HOW TO STUFF, ROLL, AND SEAR YOUR FRENCH ONION STUFFED PORK LOIN

Remember ‘Stop, Drop, and Roll’? Well, it’s ‘Stuff, Roll, and Sear’ for today. Top the pork loin with half of the cooked onions and half of the shredded cheese. It’s ready to roll! Roll up the pork loin, making sure you wrap up all that goodness inside! Then, using cooking twine, tie the rolled pork loin up to hold in all the ingredients. I used four pieces of twine if that helps. Next, sear the pork loin on all sides, using the oven-safe skillet that you used for the onions. I know it’s rolled up, so what do I mean by sides? Simply rotate it about four times to get as much of the loin seared as possible.

Next, cook the pork loin for about 25-30 minutes, making sure the internal temperature is at 145°F. Don’t worry, I did not forget about the other halves of the onions and cheese. Top the loin with both and broil for about 5 minutes, or until the cheese is melted and golden brown. Enjoy!
