These barbecue spare ribs are my go-to when friends come over for a summer cookout. The method is dead simple — you marinate the ribs in a sticky-sweet, slightly spicy glaze overnight, simmer them until they’re fall-apart tender, then finish them on a hot grill for that irresistible smoky char.
What I love about this boil-and-grill approach is that it’s practically foolproof. The simmering step does the heavy lifting, breaking down all that tough connective tissue so the ribs turn out meltingly tender every time. The grill just adds colour and a little smokiness at the end — no babysitting a barbecue for hours.
The marinade is where the magic happens: soy sauce, maple syrup, brown sugar, ketchup, garlic, and fresh chillies come together to create a glaze that’s sweet, salty, and just spicy enough to keep things interesting. And the best part? The simmering liquid reduces into a rich, glossy gravy you pour right over the finished ribs.
If you want ribs that taste like you spent all day on them but didn’t, this is the recipe to make this weekend.
Easy Barbecue Spare Ribs (Boil & Grill Method)
Ingredients
- 2.2 pounds pork spare ribs
- 4 cloves garlic crushed
- 2 fresh red chillies crushed (such as bird's eye or Fresno)
- 2 teaspoons maple syrup
- 3 tablespoons soy sauce
- 2 tablespoons tomato ketchup
- 1 teaspoon chilli powder
- 2 tablespoons brown sugar
- 1 tablespoon sesame seeds (for garnish)
- 4 cups water enough to cover the ribs
Instructions
- Trim off excess fat from the ribs and put the trimmed ribs in a large bowl.
- Add the crushed garlic and crushed chillies, together with all the remaining ingredients except the sesame seeds. Mix well with your hands or a wooden spatula. Cover the bowl with cling film and refrigerate for a minimum of 2 hours, or preferably overnight (up to 24 hours) for the best flavour.
- Transfer all the bowl contents (ribs and marinade) into a large saucepan or stockpot and add just enough water to cover the pork (approximately 1 litre / 4 cups). Bring to a boil, then reduce to a gentle simmer and cook for 30 minutes until the ribs are tender and the liquid has reduced.
- While the ribs simmer, preheat your barbecue, grill, or griddle pan to medium-high heat (approximately 400°F / 200°C). Drain the spare ribs, reserving the reduced cooking liquid.
- Place the ribs on the hot grill and cook for 3–4 minutes per side until nicely charred and caramelised. Serve hot, sprinkled with the sesame seeds, and spoon the reserved cooking glaze over the top.

What Makes These Barbecue Spare Ribs Special
Most barbecue rib recipes ask you to tend a smoker or grill for hours. This recipe flips that approach entirely — you simmer the ribs first in their own marinade, which accomplishes two things at once. The pork becomes fall-off-the-bone tender, and the cooking liquid reduces into a concentrated, glossy sauce that you pour over the finished ribs.
The marinade itself strikes a perfect balance between sweet, salty, and spicy. Soy sauce and brown sugar create a savoury-sweet backbone, maple syrup adds a subtle caramel depth, and fresh chillies with chilli powder bring a layered heat that builds without overwhelming. The garlic ties everything together.
The grill step at the end is quick — just a few minutes per side to get that smoky char and caramelised crust that makes barbecue ribs irresistible. It’s the best of both worlds: hands-off braising for tenderness, then high heat for flavour.
Equipment You’ll Need
- Large mixing bowl — needs to be big enough to hold 1 kg of ribs plus the marinade so you can toss and coat them evenly.
- Large saucepan or stockpot — the ribs need to be fully submerged in liquid, so use a pot that’s wide enough to lay them in a single layer or deep enough to stack them.
- Barbecue grill, griddle pan, or oven grill/broiler — you need direct high heat to char and caramelise the outside of the ribs after simmering. A cast iron griddle pan works well if you don’t have an outdoor grill.
- Tongs — essential for turning the ribs on the hot grill without piercing the meat and losing juices.
- Sharp knife — for trimming excess fat from the ribs before marinating.
- Basting brush (nice-to-have) — lets you brush the reduced cooking liquid onto the ribs while they’re on the grill for an extra sticky, lacquered finish.
Tips for Best Results
- Marinate overnight. Two hours is the minimum, but overnight marinating lets the soy sauce and aromatics penetrate deep into the meat. You’ll taste the difference.
- Don’t skip trimming the fat. Spare ribs have a thick fat cap on one side. Trim it down to a thin layer — enough to keep things moist but not so much that the marinade can’t reach the meat.
- Simmer gently, don’t boil hard. A rolling boil will toughen the outside of the ribs before the inside cooks through. Keep it at a gentle simmer with small, lazy bubbles.
- Reduce the cooking liquid. After draining the ribs, pour the liquid back into the pan and boil it down for 10–15 minutes. It should thicken into a syrupy glaze that clings to the ribs when you pour it over them.
- Get the grill properly hot before adding the ribs. You want immediate sizzle and char — if the grill is too cool, the ribs will dry out before they caramelise.
Substitutions and Variations
- Honey for maple syrup: Works beautifully as a 1:1 swap, with a slightly more floral sweetness.
- Tamari for soy sauce: Use gluten-free tamari if you need the recipe to be coeliac-friendly. Same quantity.
- No fresh chillies? Use 1 teaspoon of red pepper flakes or a tablespoon of sriracha mixed into the marinade.
- Baby back ribs instead of spare ribs: These are leaner and cook faster — reduce the simmering time to 20 minutes and watch them closely on the grill.
- Oven-only method: Skip the grill entirely. After simmering, place the ribs on a foil-lined baking tray, brush with the reduced glaze, and grill/broil in the oven at 220°C / 425°F for 5–7 minutes until charred and bubbling.
- Extra smoky flavour: Add 1 teaspoon of smoked paprika to the marinade, or use a few drops of liquid smoke.
Storage and Reheating
- Fridge: Store leftover ribs and sauce separately in airtight containers for up to 3 days.
- Freezer: Wrap individual portions tightly in cling film, then place in a freezer bag. Freeze for up to 3 months. Thaw overnight in the fridge.
- Reheating: Place the ribs on a baking tray, spoon some reserved sauce over the top, cover loosely with foil, and reheat at 160°C / 325°F for 15–20 minutes until heated through. Remove the foil for the last 5 minutes to re-crisp the glaze. Avoid microwaving — it makes the texture rubbery.
What to Serve With This
- Coleslaw — the cool crunch cuts through the rich, sticky ribs perfectly.
- Steamed jasmine rice — ideal for soaking up every drop of that reduced cooking glaze.
- Corn on the cob — throw it on the grill alongside the ribs for a classic summer plate.
- Quick pickled cucumbers — the acidity and freshness balance the sweetness of the marinade.
- Grilled flatbreads — warm bread to wrap around the rib meat if you pull it off the bone.
Frequently Asked Questions
Can I make these barbecue spare ribs in the oven instead of on a grill?
Yes. After simmering, place the drained ribs on a foil-lined baking tray, brush generously with the reduced cooking liquid, and grill/broil at 220°C / 425°F for 5–7 minutes per side until charred and sticky. Watch them closely — the sugar in the glaze can burn quickly under a broiler.
Why do you boil the ribs before grilling them?
Simmering the ribs in their marinade liquid tenderises the tough connective tissue in spare ribs, which normally requires hours of low-and-slow smoking. It also infuses the meat with flavour from the inside out. The grill step afterwards adds the smoky char and caramelised crust. It’s a shortcut that delivers excellent results.
How do I know when the ribs are done simmering?
After 30 minutes of gentle simmering, the meat should have pulled back slightly from the ends of the bones, and a fork should slide into the thickest part with very little resistance. If the ribs still feel tough, simmer for another 10 minutes.
Can I use this marinade on other cuts of pork?
Absolutely. This marinade works brilliantly on pork belly slices, pork shoulder steaks, and even bone-in pork chops. Adjust the simmering time — thinner cuts will need only 15–20 minutes.
What type of chillies should I use?
Bird’s eye chillies give a sharp, clean heat. Fresno chillies are milder with a slightly fruity flavour. Use whatever you have — or reduce to one chilli if you prefer less heat. Remove the seeds before crushing for a gentler spice level.
The cooking liquid is too thin — how do I thicken it?
After draining the ribs, return the liquid to the pan and boil it uncovered over medium-high heat for 10–15 minutes. It will reduce and thicken into a glossy, syrupy glaze. If it’s still not thick enough, mix 1 teaspoon of cornflour with 1 tablespoon of cold water, stir it in, and cook for another 2 minutes.
The History Behind Barbecue Spare Ribs
Barbecue spare ribs have roots in both American Southern cooking and various Asian culinary traditions. In the American South, slow-smoked pork ribs became a staple of barbecue culture from the 18th century onwards, with regional variations developing across Texas, Memphis, Kansas City, and the Carolinas. Meanwhile, in Chinese and Southeast Asian kitchens, pork ribs have been braised in soy-based sauces with garlic, chilli, and sugar for centuries. This recipe sits at the crossroads of those traditions — using an Asian-inspired marinade of soy sauce, sesame seeds, and fresh chillies, finished with the American barbecue technique of charring over open flame. The boil-then-grill method itself is popular across many cultures as a practical way to achieve tender ribs without specialist smoking equipment.
