The Perfect Pork Tenderloin Recipe from Southern Smoke’s Matthew Register

Southern Smoke Matthew Register

Just because the temperature is slowly dropping does not mean you should stop grilling. In fact, what better way to stay warm when it’s a little cooler out than to be standing near your grill? (Bourbon is a good way to stay warm, too, but we’re trying to make a point here.)

What we’re trying to say is that you should be grilling until you physically can’t grill because of snow, et cetera. The next question, then, is what to grill? Burgers and dogs are so (literally) last summer, so you need to move on to heartier fare that will stick to your ribs and fill you up.

We reached out to Matthew Register, creator of the Garland, North Carolina barbecue joint Southern Smoke (and author of the newly-released ), to see what he would suggest for a great fall grilling recipe.

Below, check out his recipe for grilled pork tenderloin with tomato and greens ragu. It is sweet, salty, warm, and hearty all at once and we plan on cooking it all autumn long.

Grilled Pork Tenderloin with Tomato and Greens Ragu Recipe

Southern Smoke Grilled Pork Tenderloin with Tomato and Greens Ragu Recipe
Harvard Common Press

(Serves 4)

“I’ve done a lot of cooking in an unassuming house in Sledge, Mississippi. It’s not a fancy kitchen. The countertops are often cluttered with duck calls, coffee cups, and the occasional wine glass. The reason I love this kitchen is the people I’ve shared it with: My father, uncle, cousin, and friends. After a day of hunting, this is the recipe I’ll make, served up family-style on a huge platter. The ragu — which gets its sweetness from the tomatoes, aided by the garlic — is a perfect way to use fresh greens to liven up a basic grilled pork tenderloin. When it’s poured over the top of the rich pork loin, the ragu creates a perfect balance of sweet and salty heartiness that will warm your soul.”

Ingredients for the ragu:

  • 4 tsp (20 ml) olive oil
  • 1 medium onion, diced
  • 2 cloves garlic, minced
  • .25 tsp red pepper flakes
  • 5 cups (150 g) greens, such as spinach, escarole, or turnip
  • 2 cans (14½ ounces [411 g] each) diced tomatoes
  • 2 whole pork tenderloins (about 1 pound [455 g] each)

Ingredients for the pork tenderloin rub:

  • 1 tsp garlic salt
  • 1 tsp freshly ground black pepper
  • 1 tsp dried parsley
  • .5 tsp dried oregano
  • .5 tsp garlic powder

Method for the ragu:

  1. In a medium saucepan, heat the olive oil over medium heat. Add the onion and cook, stirring often, until softened, about 3 to 5 minutes.
  2. Add the garlic and red pepper flakes and stir. Cook for about 1 minute.
  3. Stir in the greens and cook for 2 minutes, or until they begin to wilt.
  4. Reduce the heat to medium-low and add the tomatoes. Simmer for 10 minutes, then reduce the heat and cover to keep the ragu warm while you grill the pork loins.

Method for the pork and pork rub:

  1. Prepare a charcoal grill (see page 25). Meanwhile, in a small bowl, combine the rub ingredients and stir with a fork until well mixed. Pat the rub onto the tenderloins and let them sit at room temperature while your grill heats up.
  2. Once the grill is ready, place the tenderloins over direct heat.
  3. Cook the tenderloins for 5 to 7 minutes per side and try to flip them only once. After cooking on both sides, check the internal temperature.
  4. From here, the goal is to get the tenderloins in the 140°F to 145°F (60°C to 63°C) range without overcooking them. To do this, move them over indirect heat and continue to cook until they reach the correct internal temperature, about 18 minutes total cooking time.
  5. Remove the pork from the grill and let it rest for 10 minutes.
  6. Slice the tenderloins in ¼-inch (0.5 cm) slices and place on a large platter. Spoon the ragu over the top and serve immediately.

Shandies and Radlers are summer classics — these are our favorites
Shandies and Radlers are the perfect summer crushers
Leinenkugel's

When it comes to refreshing alcoholic beverages, it’s difficult to beat the appeal of a shandy or Radler. We already love a crisp, refreshing beer on its own, a glass of tart lemonade, or a citrus-flavored soda. So, it only makes sense to combine the two to make an epic, thirst-quenching, boozy, sweet, tart beverage.

Shandies versus Radlers
The classic shandy is a lemon-flavored beer that is made by combining (usually) a 50/50 mix of lemonade (or a lemon-based drink) and a crisp, refreshing beer. Originally called “shandygaff”, the mixture has its origins in England in the late 1800s.

When it comes to summer drinks, isn't there something awfully tempting about a gas station slushie? These drinks may not be subtle or sophisticated in terms of flavor, but there's something undeniably satisfying about the crunchy texture of ice crystals. And for my fellow cocktail enthusiasts, there's a lesson here about texture. You can create something similar in terms of barely-frozen ice that's perfect for summer sipping, and you can do it with far more interesting and complex boozy flavors. It's also shockingly easy to do at home.

What you're going to want to do is make a prosecco granita.
How to make prosecco granita
It really couldn't be simpler to make a granita. All you need to do is take a bottle of prosecco (or other fizzy wine of your choice -- even Champagne if you're feeling fancy) and add a few tablespoons of sugar and any other flavoring ingredients you want. Pour your mixture into a wide, shallow pan (ideally, the liquid should be no more than an inch deep for quick freezing) and then pop the tray into the freezer.

Kabobs on the grill

There's something so fun about a kebab...or kabob...or kabab. No matter how you spell it, it's food on a stick, and food on a stick is always a hoot. These grilled little treats are always a massive hit at barbecues for their obvious charm, delicious smokey flavor, and the incredible convenience of having an entire meal on one simple skewer. But in addition to their deliciousness and beauty, there are a few potential kebab pitfalls to be wary of before lighting up that grill. Here are a few tips and tricks that will help you grill perfect kebabs every single time.
Choose the right meats

First things first: always steer clear of the pre-cubed stuff they sell at the grocery store alongside the proper cuts. The time you save (about two minutes) is not worth the lackluster, sloppy scrap cuts you get in these packages - not to mention the added cost. Opt for whole pieces, and do the knife work yourself. It isn't hard to cut meat into chunks.
