Grilled Pork Loin Roast: Who Needs an Oven when You have a Grill?

Posted by Matt on Jul 22, 2019


If you’re anything like me, you despise turning on the oven when the thermostat climbs over 90 as it has the last couple of weeks. What a lot of people don’t realize is that there is a wonderful tool sitting right in your backyard to help with this: the grill. Using your grill to give whatever you’re cooking that char that everyone loves and then turning down the heat to finish your food slowly is a great way to cook a larger piece of meat without burning it or having to turn on the oven when your AC is already working hard.

Pork is a lot leaner than it was in the past because of the way most pigs are now raised. A great way to combat the natural dryness of a pork loin roast is to brine it. Brining adds flavor, and more importantly, moisture to any meat you think could use a boost of both. Grilling has a tendency to dry your meat out if you’re not careful so brining it before you grill it is a great fail-safe. What I like to do is make my brine the night before, let it cool in the fridge overnight, and then pour the brine over the pork roast before I leave for work. You can always do it overnight but I don’t like to add ice to my brine, so I usually let it cool without adding ice.

Another great way to add flavor to pork roasts is to make a barbecue sauce. Keep in mind that just because you add barbecue sauce to a piece of meat does not qualify it as now being barbecue. True barbecue involves smoke and this method does not involve smoke. So even though it isn’t barbecue in its true form, it is still delicious nonetheless.

I like my barbecue sauce as kind of a hybrid between the sweet Kansas City style and the mustard-based sauces that are popular in the Carolinas. The great thing about barbecue sauce is that it can easily be altered to better fit your taste. If you like it a little sweeter, add more brown sugar, or try adding some dark molasses. If you like your sauce a bit more on the tangy side, add more vinegar or mustard. You can also easily change the spices. I like a little heat in my barbecue sauce so I like to add cayenne pepper and hot sauce. I also like the smoky note you get from ground cumin. The addition of ground ginger also gives you a little something on the back of your tongue that makes you think “What is the spice I’m getting in the background?” Barbecue sauce is a very versatile and personal thing so make it the way you like it.

Grilled Pork Loin Roast

For this recipe, I used a 2# roast.

1. Set your grill up for indirect grilling. (I have a 5-burner grill, so I turn 2 of the burners on high and leave the rest off.)

2. Allow grill to heat on high for 10-15 minutes.

3. Season pork roast with salt and pepper. (Be judicious, remember the brine has a lot of salt in it, you just need a little to help build a crust.)

4. Sear the pork on the hot part of the grill until well-marked on all sides. About 4-5 minutes per side.

5. Once the roast is marked, move it to the cooler side of the grill and baste with your homemade barbecue sauce.

6. Grill until your roast reaches an internal temperature of 135 for a nice medium, about 35-40 minutes, turning and basting with more of the BBQ sauce every 5-10 minutes. (It will carry over another 5-10 degrees.)

7. Allow roast to rest 10-15 minutes.
