Easy-to-Follow Steps
- Spread the Cajun Sauce:
- In a bowl, stir together mayo, Worcestershire, lemon juice, garlic powder, pepper, smoked paprika, and Tony's Lite. Blend until it's creamy and pop it in the fridge so flavors mingle while you do the rest.
- Mix Up the Cajun Burger Rub:
- Combine garlic powder, black pepper, smoked paprika, onion powder, and more Tony's Lite in a tiny bowl. Just stir gently so everything's mixed up well.
- Shape and Chill the Burgers:
- In a big bowl, gently fold ground chuck, cheese cubes, and Tony's Marinade by hand until just combined. Grab a chunk (about 1/3 to 1/2 pound), flatten to about half an inch thick, and place it on parchment. Freeze the formed patties for twenty minutes to help them keep shape later.
- Get the Onions Jammy:
- Melt butter in a pan over medium. Toss in onions and salt. Stir every now and then for thirty to forty minutes till the onions are super soft, brown, and almost like jam. If they start to burn or stick, turn down the heat and splash in a bit of water.
- Smoke Those Burgers:
- Set your smoker to two fifty to two seventy-five with hickory. Place firmed-up burgers on the rack. Let them hang out smoking thirty to forty minutes. Top each with a Colby Jack slice just before they're done so it melts. Internal temp should hit one sixty-five. Take them off and let sit for six minutes. Toast up those buns meanwhile.
- Build Your Burger:
- Spread a big spoonful of sauce on your toasted bun bottom. Stack a cheesy smoky patty right on top. Pile on the onions, add more sauce if you want, and squish on the top bun. Dig in while they're still hot!

Best part? Hiding those cheese cubes in the burger mix. First time I did this they melted perfectly during game day and everyone wanted my cheese-stuffing secret. I keep it up now and folks are always wowed.
Storage Advice
Got leftovers? Let burgers cool then wrap them tight and stash in the fridge for up to two days. Warm them up, covered, in a three hundred degree oven to keep the cheese gooey. Uncooked patties can be frozen up to a month—just let them thaw in the fridge before you fire up the smoker.
Swap-Out Ideas
Can't find Tony's spices? Use any fave Cajun or Creole blend instead. For cheese inside, Monterey Jack or cheddar can work, but if you want a creamy kick, pepper jack is the winner. Missed the marinade? Splash on some hot sauce mixed with olive oil. If you're out of brioche or potato buns, any sturdy bread will do the trick.
Serving Vibes
Pile extra onions on top for serious sweet-and-savory action. Pair with sweet potato fries, a bright corn salad, or heap on pickles for crunch. They're awesome with backyard BBQ classics or a crisp green salad on the side too.

Fun Background
Cajun cooking comes from Louisiana, mixing French Acadian and Southern traditions. Big flavors, grill smoke, and spicy comfort food set these burgers apart. Hickory-smoked patties bring that old-school Southern BBQ feel to every bite.
