Spicy Barbecue Pork Roast

This Spicy Barbecue Pork Roast is magnificent with its juicy interior and very flavorful spicy crust on the outside. A great recipe to have Sunday dinner and the family over. One of the simple pleasures in life is cooking pork on the barbecue.

This roast is the perfect recipe for a beautiful pork rib roast! My roast was just over 7 pounds. Don’t be intimidated by the size, it’s as easy to also do a smaller roast.

There are so many ways to cook a pork roast. The choices are almost endless, from the oven to the rotisserie. You can smoke it, put it on the grill, or barbecue it like I did this time. The one general consistency is that you should cook it low and slow.

I often do a rub for my pork roasts or ribs, but for this recipe, I created almost a sauce or a paste if you will that you can slather on. It creates a crust on the outside of the roast which also helps to seal in the juices and the flavors!

How do you BBQ a pork roast?

The first thing you do when you are going to barbecue a pork roast is to find a really great roast! Like the one I got from our local meat vendor Ryan at R.F.G Meat and Seafood. This roast is something that you would see Fred Flintstone enjoying (did I give away my age?). Once you find a great meat vendor or butcher you should make sure you stay in touch with them; they will get you the best product that is available!

The next thing to do is to score the fat cap using a sharp knife. You want to create a crosshatch pattern in the fat about a 1/2 inch deep. This allows the seasonings to permeate the meat.

Now you needed to make the paste to coat the outside of the pork roast. Add garlic, onion, jalapeno peppers, oregano, cumin, ancho chile powder, Kosher salt, fresh ground pepper, cider vinegar, and olive oil to a food processer. Process until you have a paste.  Rub the mixture all over the pork roast making sure that you cover all sides and you massage it into the scored fat cap. 

Because we are going to be cooking this beautiful pork roast using the indirect method on your barbecue I like to put an aluminum pan under the grate. It catches any of the fat that drips off the roast. This helps to avoid flare-ups and keep your barbecue from getting too dirty, so cleanup is a breeze. I’m all about making things as easy as possible, especially when it comes to cleaning up!

Ingredients:

  • Pork rib roast (a pork loin roast will also work)
  • Garlic, peeled (you could use garlic powder in a pinch)
  • Onion coarsely chopped
  • Jalapeno peppers ribs and seeds removed and coarsely chopped
  • Dried oregano
  • Ground cumin
  • Ancho chili powder
  • Kosher salt and fresh ground pepper to taste
  • Apple cider vinegar
  • Good olive oil

How long does it take to Barbecue a pork roast?

The question is not how long does it take to barbecue a pork roast. The question should be at what temperature is my pork roast done. As with all meat, the cooking time will vary. You should never cook a roast for a certain period of time; you should cook it to the proper internal temperature. Having a good instant-read thermometer is critical to a great barbecue. I used my Thermoworks Chef Alarm cooking alarm thermostat which is perfect for all types of roasts.

Preheat your grill on high heat, place the roast on the side of the grill where the heat is off, and reduce the heat to medium-low, 325 – 350 degrees F. 

You are going to want to cook your pork to an internal temp of 145 – 148 degrees F, depending upon your preference. Your roast will be slightly pinkish if you are close to 145; if let it go to 148, it will be less. We cooked ours to 148F and then let it rest.

Slicing the BBQ pork roast on a wooden cutting board

When I was growing up everyone said you had to cook pork until there was no pink, which of course meant that the pork was very dry. Today we understand that pork is best served at 160 degrees (after resting) or below and that pink is OK. This, of course, makes for a much juicier and tender bite of pork on your fork! 

Whatever temperature you cook your roast to, be it a pork tenderloin, a grilled pork chop, or a rib roast, you need to make sure you allow it time to rest.  After you remove it from the heat you should loosely wrap it in foil. Make sure that it rests for at least 15 to 20 minutes before carving.

    Fantastic!!!
    Great receipt and the family enjoyed it.
    Can I cook this receipt in an air fryer? If so, what do I need to do different?
    Have looked on the internet, but no recommendations available.

      Glad you enjoyed it! As for your air fryer question I’m sorry, I can’t help you. I have never tried to cook the pork roast in a air fryer.
