Classic BBQ Lamb Ribs

I never thought I’d be the person grilling lamb ribs in my backyard, but here we are. For the longest time, I stuck to the usual suspects—pork ribs, chicken, maybe beef if I was feeling fancy. But then I grabbed a rack of lamb ribs at the store on a whim, slathered them with BBQ sauce and a simple spice rub, and tossed them on the grill.

Turns out, lamb ribs are way easier than I expected. They cook up tender, soak in all that smoky flavor, and honestly? They’re not that different from pork ribs if you go with Australian lamb, which has a milder taste. No fancy techniques needed—just a good rub, your favorite BBQ sauce, and a little time on the grill.

What Kind of Lamb Ribs Should I Use?

When shopping for lamb ribs, you’ll typically find two main types at the butcher counter: spare ribs and riblets. Spare ribs are meatier and come from the belly area, while riblets are smaller cuts from the breast area that cook a bit faster. Either one works great for this recipe, though spare ribs will give you more meat to work with. If you’re buying from a regular grocery store, you might need to ask the butcher specifically for lamb ribs since they’re not always displayed with the other cuts. Fresh is always best, but frozen lamb ribs are perfectly fine too – just make sure to thaw them completely in the refrigerator overnight before cooking.

Options for Substitutions

This recipe is pretty straightforward, but here are some swaps you can make if needed:

• Lamb ribs: If lamb isn’t your thing or you can’t find it, beef short ribs or pork spare ribs work great with this same seasoning blend. Keep in mind that cooking times may vary slightly depending on the meat you choose.
• Smoked paprika: Regular paprika can step in if you don’t have the smoked version, though you’ll lose a bit of that smoky depth. You could also try a tiny pinch of cumin for a different flavor profile.
• Cayenne pepper: If you prefer less heat, feel free to cut the cayenne in half or skip it altogether. For more kick, add an extra 1/8 teaspoon or swap it with crushed red pepper flakes.
• BBQ sauce: Any BBQ sauce you have on hand will work – whether it’s sweet, tangy, or spicy. You can even make a quick version by mixing ketchup with brown sugar, vinegar, and worcestershire sauce.
• Spice blend: In a pinch, you can replace the entire spice mix with about 2 tablespoons of your favorite BBQ rub or steak seasoning.

Watch Out for These Mistakes While Grilling

The biggest mistake when grilling lamb ribs is cooking them over direct high heat the entire time, which will char the outside while leaving the inside tough and chewy – that’s why you need to start with indirect heat to let the meat cook through slowly.

Skipping the step of scoring the fat cap is another common error, as those shallow cuts help the fat render properly and allow your spice rub to penetrate the meat instead of just sitting on the surface.

Don’t add your BBQ sauce too early or it’ll burn and turn bitter – wait until the last 10 minutes of cooking when the ribs are almost done, and apply it in thin layers rather than drowning the meat.

Finally, resist the urge to slice into those ribs right away; letting them rest for 5-10 minutes allows the juices to redistribute throughout the meat, keeping each bite tender and moist.

What to Serve With BBQ Lamb Ribs?

BBQ lamb ribs are perfect with classic cookout sides that can handle all that smoky, tangy flavor. I always go for creamy coleslaw and baked beans – they’re cooling and hearty enough to balance out the richness of the ribs. Cornbread or dinner rolls are great for soaking up any extra BBQ sauce on your plate, and you can’t go wrong with some grilled corn on the cob slathered with butter. For something a bit lighter, try a cucumber and tomato salad or some crispy potato wedges on the side.

Storage Instructions

Store: Leftover BBQ lamb ribs keep really well in the fridge for up to 4 days. Just wrap them tightly in aluminum foil or place them in an airtight container. They actually taste even better the next day once all those spices and BBQ sauce have had more time to soak in.

Freeze: These ribs freeze great for up to 3 months. Let them cool completely, then wrap individual portions in plastic wrap followed by foil, or use freezer-safe containers. This way you can pull out just what you need for a quick dinner later.

Reheat: The best way to reheat these is in the oven at 300°F wrapped in foil for about 20-25 minutes until warmed through. You can also use the microwave in a pinch, but the oven keeps them from drying out and helps maintain that nice texture on the outside.

Ingredients

For the ribs:

• 4.5 lb lamb ribs (preferably Australian lamb for a milder flavor)
• 1/2 cup bbq sauce (such as Sweet Baby Ray’s Original)

For the spice rub:

• 2 tsp salt
• 1 tsp garlic powder
• 1 tsp onion powder
• 1 tsp chili powder
• 1 tsp smoked paprika
• 1/4 tsp cayenne
• 1 tbsp brown sugar
• 1/2 tsp dry mustard powder

Step 1: Prepare the Ribs and Create the Dry Rub

• 4.5 lb lamb ribs
• 2 tsp salt
• 1 tsp garlic powder
• 1 tsp onion powder
• 1 tsp chili powder
• 1 tsp smoked paprika
• 1/4 tsp cayenne
• 1 tbsp brown sugar
• 1/2 tsp dry mustard powder

Remove the ribs from packaging and place them on a cutting board.

Using a sharp knife, score the fat cap in a crosshatch pattern, cutting about 1/4 inch deep—this helps the rub penetrate and allows fat to render during cooking.

In a small bowl, combine all the dry spices: salt, garlic powder, onion powder, chili powder, smoked paprika, cayenne, brown sugar, and dry mustard powder.

Stir until evenly mixed.

Generously rub this spice mixture all over both sides of the ribs, pressing gently so it adheres to the meat.

Let the ribs sit at room temperature for 15-20 minutes while you prepare the grill—this helps them cook more evenly.

Step 2: Set Up the Grill for Indirect Heat

Preheat your grill to medium heat (around 325-350°F), creating a two-zone setup: one side at medium heat and the other side turned off or set very low.

If using a charcoal grill, push coals to one side.

This indirect cooking method is essential for lamb ribs—it prevents the exterior from charring while the interior stays tough.

I prefer starting on the cooler side of the grill because it gives the meat time to cook through gently before any browning happens, which keeps the meat incredibly tender.

Step 3: Slow-Cook the Ribs Low and Slow

• Seasoned lamb ribs from Step 1

Place the ribs bone-side down on the cool side of the grill (away from direct heat).

Close the lid and cook for 20 minutes without disturbing them.

This low-and-slow approach allows the fat to render and the meat to become tender.

Flip the ribs over and cook for another 20 minutes.

At this point, the ribs should be mostly cooked through and beginning to develop color—they’re still not quite done, but they’ve got great texture.

Step 4: Build Flavor with Sauce and High Heat

• Partially cooked ribs from Step 3
• 1/2 cup BBQ sauce

Increase the grill temperature to high heat (around 400-425°F).

This final phase uses direct heat to caramelize the BBQ sauce and create a flavorful glaze.

Place the ribs bone-side up on the hotter side of the grill and brush generously with BBQ sauce.

Cook for 5 minutes, then flip the ribs over, brush the other side with more sauce, and cook for another 5 minutes.

The sauce will bubble and char slightly, creating a delicious crust.

I always use a lighter touch with the sauce on the second coat—too much will burn and taste bitter, so reserve some of the best-looking ribs with the original layer of sauce.

Step 5: Rest and Serve

• Glazed ribs from Step 4

Transfer the ribs to a clean cutting board and let them rest for 5 minutes.

This resting period allows the juices to redistribute throughout the meat, ensuring each bite stays juicy and tender.

Slice between the bones and serve immediately while still warm.
