Rotisserie Pork Sirloin Roast - 20

When Grillin’ Fool Scott told me that the folks at Smithfield had asked us to try our foolishness on their line of marinated pork I wondered just what had those whippersnappers been up to. Sure, I marinated or brined pork all the time but these folks were doing it for this old dog. Well perhaps I could learn a new trick when new school meets old school out on the patio classroom. Besides, letting Smithfield marinate the pork saves me time buying ingredients for a marinade and remembering to put the meat in it the night before. I can buy one of these and put it on the grill as soon as I get home and know it will be loaded with flavor thanks to the marinade:

Rotisserie Pork Sirloin Roast - 01 Rotisserie Pork Sirloin Roast Ingredients:

23 oz Smithfield Garlic and Herb Marinated Pork Sirloin Roast
1 shallot
2 cloves garlic
2 oz chicken broth

The first thing I did after opening the package was reserve any excess marinade to use as a basting liquid during the cooking process. The aroma was already pulling me in with grilling yet to begin:

Here it is, just a shade shy of a pound and a half (23 ounces). I’ve slivered some fresh garlic and sliced a shallot to be studded all around the surface of the pork sirloin roast. I chose to keep the slivers short as this is a smallish roast. I just couldn’t resist adding my own twist to this cook but then I think most backyard cooks have a tendency to tinker with recipes a bit, don’t you?

Now for the studdin’ ‘n pluggin’!  First insert the blade of a sharp slender knife into the pork and then slide the sliver alongside the blade until hidden inside the meat. Hold the sliver in place with a finger and remove the knife. Repeat every inch or two all over the roast. I’ll show those whippersnappers!

Here’s a closer look. Some of the slivers will want to work themselves out of the roast so just give ‘em a gentle poke back in. This may also happen during the grilling process:

The roast has been stabbed and studded and now it’s been given the shaft, literally. Here comes old school again. I’m breaking out the rotisserie I inherited from my dear departed father-in-law, Russ:

Rotisserie Pork Sirloin Roast - 06 New school meet old school! Speaking of Russ, this is a stainless steel grill he made circa 1975. I spent many sunny, summer, Sunday afternoons at his lakeside home smoking pork on this grill. This newfangled marinated pork will be cooked on old school equipment:

Rotisserie hooked up, foil drip pan in place, and the pork sirloin roast is being kissed by cherry wood smoke:

This old grill I appropriately dubbed The Russ doesn’t have a thermometer like that fancy Grill Dome ceramic kamado grill shown in the background so other means were used to control both temperature and air flow. There are several small holes in the bottom to provide air intake plus the ‘air and temperature regulator’:

Let’s take a closer look at that ‘air and temperature regulator.’ Notice the different notches where the lid rested while adjusting for fire control. When the cooking was over that same doorstop shaped piece of wood was wedged between the lid and the cutting board to keep the grill lid closed tightly while cutting off the draft so he could save charcoal. Russ would frequently state something was as ‘handy as a pocket on a shirt.’ He certainly was:

Now back to grilling. We’re at 130 degrees (I’m new school enough to use an instant read thermometer now) one hour into the cook and I’ve basted with the reserved liquid with the broth added. Olive or grape seed oil would work also in place of the broth. I’m expecting an hour and a half cooking time but always cook to temperature not time. When the pork is 145-150 it should be pulled to rest. Grill it much more than that will typically yield dry meat, particularly loin or sirloin. This cut is very different than the pork butt/shoulder roasts that can be cooked to 195-200. This is a much leaner cut, in fact, it generally is lower in calories and saturated fat than beef tenderloin:

I pulled the rotisserie pork sirloin roast when it reached 140. I realize it’s not quite done. How about a reverse sear after a rotisserie? Remember that blue Grill Dome in the background of an earlier photo? It was set up for direct grilling (we had 3 grills working that day) so it was suggested we sear at the end adding to the flavor profile by caramelizing those proteins on the outside:

Searing results look fine, dontcha’ think?

After searing the rotisserie pork sirloin roast was set aside to rest for about 10 minutes. I’m anxious to see how my tinkering has enhanced the newfangled pre-marinated pork:

Notice how the garlic and onion slivers penetrated the meat? That’s flavortown!

Rotisserie Pork Sirloin Roast - 21

Did the added garlic and onion improve the flavor? I’m not sure about improve but intensify might be a better word choice. Did I need to add the garlic and shallots? Absolutely not, the pieces I tasted without the additions were moist and delicious and did not require additional salt or spices. Doing nothing extra to the marinated sirloin roast would result in delightful dining. Sliced thick would be fine for an entrée but with lean pork thinner slices provide maximum tenderness. Oh, and the follow up sandwiches would be divine. Maybe, just maybe, those whippersnappers from Smithfield have taken me back to school. And in the end, I saved a lot of time and feel good about serving this to my family because it was simply that good:

Full Disclosure ~ Smithfield provided the GrillinFools product and compensation to do this post. But as you know, we wouldn’t put anything on this site that isn’t really good and this pork roast was outstanding inside and out. Save yourself some time and add a bunch of flavor to your next barbecue and give one of these a try.

This is part of a series of posts we did for Smithfield. Check out the Hawaiian Pork Tenderloin Sliders Scott did with a couple Smithfield teriyaki pork tenderloins.

That pork roast looks good although I prefer to make my own marinades. Great post and I really enjoyed your style of writing. Thanks!



I like to make my own marinades too, but with three little kids at home and lots of other projects on my plate, I find myself going to the premade stuff more and more to save time. If I have a long weekend where I can sit back and grill for half the day, I’ll do that, but most of the time I’ll use something like this and still get all the flavor I want without losing so much time. And thanks for the compliment about the writing style. I appreciate it.
