Cajun-spiced pork shoulder and charred holy trinity vegetables slow-roasted on the grill until the meat pulls apart and the vegetables caramelize into smoky sweetness.
Ingredients
Cajun Spice Rub
- 2 tspkosher salt
- 1 tspcayenne pepper
- 1 tsppaprika
- 1 tspgarlic powder
- 1 tsponion powder
- 1 tspdried thyme
- 1 tspdried oregano
- 1/2 tspblack pepper
- 1/2 tspwhite pepper
Trinity Vegetables
- 1 largeyellow onion, cut into thick wedges
- 2 largebell peppers, green or mixed colors, cut into strips
- 4 stalkscelery, cut into 3-inch pieces
- 3 tbspvegetable oil
- 2 tbspbutter
Method
1. Season and Rest the Pork Mix all your spice rub ingredients in a bowl, then work that blend into every nook and cranny of the pork shoulder. Really massage it in—this is where the flavor starts. The salt will immediately start drawing moisture to the surface, creating a bit of brine that'll help the spices penetrate deeper. Give it 30 minutes at room temperature while you get the grill ready.
Watch for: The surface should look slightly glossy as the salt does its work
Tip: Don't rush this step—letting the meat come to room temp helps it cook evenly
2. Build Your Two-Zone Fire Bank all your coals to one side of the grill, creating a hot zone for searing and a gentler zone for the long roast. If you're using gas, fire up one side to medium-high and leave the other off. Give those grates a good scrub and oil them well—trust me on this one, as that beautiful spice crust can stick if you're not careful.
Watch for: You should only be able to hold your hand 5 inches above the hot side for 2-3 seconds
3. Sear for That Perfect Crust Place your seasoned pork directly over the hot coals and let it sear undisturbed for 4-5 minutes per side. You're building flavor here, so resist the urge to peek too early. The spices should darken to a gorgeous reddish-brown without crossing into burnt territory. That crust is going to be your reward later.
Watch for: Look for a deep mahogany color with toasty-smelling spices, not acrid smoke
4. The Long, Slow Roast Now comes the patience part. Move your beautifully seared pork to the cool side of the grill and toss those trinity vegetables with oil and any leftover spice mix. Spread them over the hot side—they're going to char and caramelize while the pork slowly works toward tenderness. Close the lid and settle in for about 3 hours, giving the vegetables a stir every 45 minutes or so. If your fire starts running cool, toss on a few more coals.
Watch for: The pork is ready when it shreds easily with a fork and hits 195°F inside
Tip: Those vegetables are supposed to get some serious char—that's where the magic happens
Equipment
- charcoal or gas grill
- instant-read thermometer
- large disposable aluminum pan
- long-handled tongs
Make ahead
- Season that pork up to a day ahead and let it hang out in the fridge—just bring it back to room temp before grilling. The spice blend keeps for a month in an airtight container.
Storage
- Leftover pork will keep happily in the fridge for 4 days. The vegetables are at their peak when fresh but will hold for a couple days if needed.
Reheat
- Warm the pulled pork gently in a covered pan with a splash of chicken stock to keep it moist. Give those vegetables a quick reheat in a skillet with a pat of butter.
Top tips
- Mix up extra spice rub and keep it in a jar—it's fantastic on chicken and fish too
- If your grill tends to run hot, tent the pork with foil after the first hour to keep the crust from getting too dark
- Don't toss those pan drippings! They're liquid gold for spooning over rice or making gravy
Substitutions
- Pork butt works just as well as pork shoulder—they're practically the same cut
- Sweet paprika will work fine if regular paprika isn't in the pantry
- Fresh thyme and oregano (use 1 tablespoon each) are lovely if you have them growing
Serve with
- Pile it over fluffy white rice and spoon those gorgeous pan drippings on top
- Stuff into crusty French bread with pickles for the most satisfying po'boys
- Turn it into breakfast hash with some fried eggs on top

Why this recipe works
Editorial notes before you cook
There's something magical about the way pork shoulder transforms on the grill—what starts as a tough cut becomes fall-apart tender while soaking up every bit of that bold Cajun spice blend. This recipe honors the low-and-slow tradition that makes Louisiana barbecue so special. The trinity vegetables cook right alongside, picking up smoky char and turning jambalaya-sweet without needing a grain of rice. You'll need a two-zone fire for this one, but don't worry—it's easier than it sounds and gives you perfect control over both the searing and the long, gentle roast.
The goal here is not just heat. It is contrast, pacing, and texture: enough richness to feel satisfying, enough brightness to keep the plate moving, and enough chile character that the spice actually tastes like something.

FAQ
The repeat questions
Can I do this on a gas grill?
Absolutely! Set up one burner on medium-high and leave the other off. Consider adding a smoker box with wood chips if you want that extra smoky flavor—it's not required, but it's a nice touch.
What if my pork shoulder is bigger than 3 pounds?
Just plan on about an hour per pound at 300°F. A 5-pounder will need closer to 4-5 hours, but the real test is that internal temperature—you want 195°F for meat that pulls apart beautifully.
How do I know when the trinity vegetables are perfectly done?
Look for deep caramelization with some gorgeous charred edges, and they should be tender all the way through. The onions turn golden brown, and those peppers get some beautiful blackened spots—that's exactly what you want.
