This recipe was given to me by Dave Riley. Yes, that Dave Riley. This recipe is so simple I wasn’t expecting much. I mean it’s pretty much just three ingredients. Well, I was wrong on that one. This Sweet Heat Cajun Ribs recipe is as delicious as it is simple. 
Sweet Heat Cajun Ribs Ingredients:
- 1 slab spare ribs, membrane removed
- Riley’s Cajun Seasoning (or use whatever cajun/spicy seasoning you have access to)
- 2 cups brown sugar, reserved for later

Riley’s is available all over the midwest. You can also get their seasoning online. Oh, this post is not sponsored by Riley’s, they’re just good people and make a great product I believe in. If you are from St. Louis, you can also try this similar recipe using the iconic Red Hot Riplets seasoning.
Now back to this Sweet Heat Cajun Ribs recipe.
Remove the membrane off the bone side of the ribs and then coat it heavily with the Cajun Seasoning. Lay it on thick:

Flip over and repeat:

If you are worried that the ribs will be too spicy, don’t sweat it. HAHAHA! See what I did there? Sweat? Trust me, it won’t be that spicy. Actually not hot at all. More on this later.
How to Grill Sweet Heat Cajun Ribs
Prepare the grill for two zone/indirect grilling with coals and smoke wood (in this case cherry wood) on one side and nothing on the other. For this grill, coals on the bottom and a place setter between the meat and the fire inside my kamado style grill. Target internal temperature of the grill is 250F:

If you want to know what smoke woods pair with what meats, we have quite the extensive list.
Notice the white stuff in the background and flakes on the meat? That would be a glorious snow storm:

Other, normal people, when the weather casters predict snowmageddon, stock up on milk, bread and eggs. I have no idea why French toast is so popular when it snows. Me? I buy ribs and beer!
Close the lid for two hours:

After two hours the ribs have become a wonderful golden brown and the rub is now stuck tight to the meat:

That little chunk off to the side was part of the flap at the end of the ribs. I decided to make it a little pitmaster’s prerogative and do some quality control. The quality was marvelous.
Time to add the Sweet to the Heat
Take the ribs inside at this point and put on two sheets of aluminum foil (otherwise known as the Texas Crutch) and get that brown sugar out:

Make sure you use two sheets of foil because if you poke a hole in the bottom the best part of this recipe will be lost.
Since making this recipe, I have started doing foil boat ribs where the foil is open on top allowing more smoke to penetrate.
Lay the ribs meat side up and give them a thick layer of brown sugar (about 3/4 cup of sugar):

Pat the sugar down so it sticks to the meat and then flip them over to the bone side and repeat with another 3/4 cup of brown sugar:


I added the rest of the sugar to the bone side and closed up the foil:

Put the foiled ribs back on the grill for 2.5-3 hours at 250-300. Don’t worry if the temperature spikes a little. The foil and the fat and the sugar will keep the ribs from drying out.
After 2.5-3 hours remove the foiled ribs from the grill and take a look:

This is why the ribs were bone side up and extra brown sugar added:

That pooled liquid sugar, combined with the fat that rendered out of the meat and the heat of the cajun seasoning is your ticket to flavor town, my friend.
But are they done? Let’s check the bones:

I’d give that a resounding yes.
Now for what brings this whole recipe together into the genius that it is. Slice the ribs and then spoon that wonderful sauce from the bottom of the foil over them:

The sauce is sweet and thick with just a little heat to it that perfectly balances the spiciness of the Cajun Seasoning. I was floored at how terrific these ribs were. I’m doing these for a crowd soon. They are the perfect ribs for a big crew as they are extremely simple leaving time to prep for the party and enjoy company of your guests when they arrive.

I made your recipe for the Sweet Heat Cajun Ribs on Sunday May 26. I followed your recipe exactly and the outcome was delicious! That one slab (I had others slow smoked with sauce) was the hit of the BBQ.
Thank you so much for all that you do to help educate and inform us on gilling techniques and new recipes.
Scott
Bob,
Glad they came out well! They are a staple around here!

I just finished eating ribs cooked with this recipe.I would have to say that they are the best ribs I have ever cooked,and one of the top five I have ever ate.The brown sugar sauce made the meat moist,and was a real sweet(almost molasses like) addition to the flavor.
Scott
Jamie,
I didn’t have high hopes for those ribs. I figured they would be OK, maybe even good, but I never expected them to be that fantastic! Glad you enjoyed them…

I tried this recipe out a couple weeks back for my wife’s family and it was amazing, probably in the top 5 ribs I’ve ever eaten. I paired the ribs with the BBQ Baked Beans, another personal favorite. The family always has kind things to say about my grilling. But this time, they were totally speechless!
It took 3 different stores to find Cajun seasoning, but it was well worth it (Dierberg’s is the best).
Thanks for the great recipe, keep it up!

Scott
Jeff,
Glad to hear they were such a hit. Did you get Riley’s at Dierberg’s? I thought they were still negotiating. I know they carry it at Schnuck’s and Sam’s….
…….Scott
Jeff
Scott,
I could not find Riley’s or an off brand for that matter at my local Schnuck’s (Maryland Heights). Finally, I ended up at Dierberg’s which also did not have Riley’s, but the substitute looked good and ended up doing just fine.
I guarantee that I’ll be making these ribs again, so next time hopefully I can find Riley’s. I didn’t check Sam’s, so I’ll have to look for it next time I’m there.
Thanks again,
Jeff

By the way, your Brown Sugar sauce in the picture is much brighter red than mine was. I wouldn’t imagine that the cajun seasoning has anything to do with that. Any other thoughts?
Scott
Schnuck’s might only have the regular seasoning. You can get the Cajun at Sam’s. Or you can order from them online. As far as the red in the sauce, I’m guessing there is a lot of paprika in the rub and probably red pepper. Otherwise, I have no idea.
Ron Waters
I have to say I made these ribs 2 weeks ago and doing them again for family and friends as I am writing this, this recipe is so damn good!!!!! These are the best ribs I have ever smoked!!!! Thanks for the recipe you make a lot of us back yard bbq’rs look like were pro’s…..
Scott
Ron,
Glad to hear you like them so much. I was as floored as you are. I’ve made them more than any other rib recipe since I made them the first time in the winter!

The recipe calls for one slab, but I assume you can do several at once (just bump up the amount of brown sugar)? Also, will baby back ribs work just as well as spare ribs? If so, are any changes needed to the recipe (temperature, time, etc.)? Thanks!
Scott
Tom,
Absolutely you can up the ingredients for more slabs. If doing baby backs, I would cut the times down by about 25-33%, unless the BBR’s are uber thick. Other than that, same process…
…….Scott
Patrick
If I don’t have a place setter for my weber charcoal grill, does it change the way I cook the ribs?
Scott
Patrick,
Put the coals on one side, ribs on the other on the kettle…

I made these last weekend and they were great! This is my new go to way for ribs.
Marg
Hi Scott
Very hot here in Broome WA but I cook ribs with your super easy recipe. Hope it come out very good coz it’s still in grill
This is all I can say is the most easiest way to cook the ribs n if it’s come terrific, I will put this on my menu for my food van business
Will let you know but I’m truly sure it will be amazing
Thankyou heaps
Scott Thomas
So how did they come out, Marg?
…….Scott
John D
When making this recipe with baby back ribs you mentioned cutting down the cook time. Will that give the brown sugar enough time to dissolve in the foil?
Scott Thomas
John,
Absolutely. The brown sugar starts to melt as soon as you place it on the ribs…

Scott,
Looking for a “sweet-heat” for some ribs they all seemed basically the same but his one. HOWEVER I was a bit leery by the other comments. We all know how many recipes we look at and they always seem to say “the best …… ever”. That always worry me due to that fact they don’t typically live up to the hype.
HFC (holy freak’n cow). They came out great, the idea of the Cajun Spice makes it. I had to modify it a bit for my pellet smoker. (basically 1 hr at 180 of smoke then 1.5-2 hrs at 300 in the foil). Since then I have tried this with baby backs with the same results… I also did a slight variation by changing the brown sugar out for maple syrup with the same results.
Honestly the best ribs and really easy to duplicate time after time.
