Instant Pot Spare Ribs Recipe: Pressure-Cooked Smoky-Sweet Glaze

Pressure cooking transforms spare ribs into fall-off-the-bone perfection in a fraction of traditional time. This method locks in moisture while creating a caramelized glaze that clings to every rib.

I developed this recipe after testing multiple approaches to achieve restaurant-quality results at home. The Instant Pot delivers tender meat with a smoky-sweet finish that rivals slow-cooked versions.

With just 30 minutes of active prep and pressure cooking, you get ribs that are juicy inside with a sticky, flavorful crust. The secret is in the timing and glaze application.

Perfect for weeknight dinners or impressing guests with minimal effort. Here’s how to make them.

Ingredients for Instant Pot Spare Ribs

These ingredients deliver restaurant-quality ribs with a smoky-sweet caramelized finish in record time.

The spare ribs are the foundation—look for well-marbled pork spare ribs at your butcher or Costco for best results. The meat should have visible fat streaks for moisture and flavor. For the glaze, Heinz ketchup and Domino brown sugar are reliable choices. Freshly ground black pepper and quality smoked paprika (I prefer McCormick) elevate the flavor profile significantly.

No apple cider vinegar? White vinegar or lemon juice at the same amount works in a pinch. For a sugar-free option, sugar-free maple syrup can replace brown sugar. If you don’t have Worcestershire, soy sauce with a dash of molasses mimics the depth. The liquid smoke is optional but adds authentic barbecue flavor—Wright’s is the gold standard.

Prepared ribs keep in the fridge for 4-5 days and reheat beautifully. The glaze can be made ahead and stored separately for up to 1 week. For best results, apply the glaze just before serving to maintain that sticky, caramelized finish.

Step-by-Step Instructions for Pressure-Cooked Smoky-Sweet Spare Ribs

Master this technique for fall-off-the-bone ribs with a glossy, finger-licking glaze.

Step 1: Prepare and Season the Ribs

Cut the 2.5 lb Pork Spare Ribs into individual ribs if not already separated. Pat them completely dry with paper towels—this ensures a better sear and helps the seasoning adhere properly.

In a small bowl, combine the 1 tsp Smoked Paprika, 1 tsp Garlic Powder, 1 tsp Onion Powder, 1 tsp Salt, and 0.5 tsp Black Pepper. Rub this mixture evenly over all sides of the ribs, pressing gently so the spices stick. Let them sit at room temperature for 10 minutes while you prepare the glaze.

Step 2: Sear the Ribs for Depth of Flavor

Set your Instant Pot to the “Sauté” function on high heat and add the 1 tbsp Olive Oil. Once the oil is shimmering, working in batches if necessary, sear the ribs for 2-3 minutes per side until deeply browned.

Avoid overcrowding the pot—this steams the ribs instead of searing them. The goal is to develop a rich fond (those browned bits) on the bottom of the pot, which will dissolve into the cooking liquid and amplify the flavor of your final dish.

Step 3: Pressure Cook for Tenderness

After searing all the ribs, pour in the 1 cup Beef Broth and use a wooden spoon to scrape up any browned bits from the bottom. Add the ribs back to the pot, stacking them if needed. Secure the lid, set the valve to “Sealing,” and cook on high pressure for 25 minutes.

Once the cooking time is complete, allow a natural release for 10 minutes, then manually release any remaining pressure. The ribs should be fork-tender at this stage, with the meat easily pulling away from the bone.

Step 4: Create and Apply the Glaze

In a medium bowl, whisk together the 0.75 cup Ketchup, 2 tbsp Apple Cider Vinegar, 0.5 cup Brown Sugar, 2 tbsp Worcestershire Sauce, 1 tsp Liquid Smoke, and 1 tbsp Yellow Mustard until smooth. This glaze should be thick but pourable.

Drain the ribs, discarding the cooking liquid, and return them to the Instant Pot. Pour the glaze over the ribs and toss gently to coat evenly. Set the Instant Pot back to “Sauté” on medium heat and cook uncovered for 5-7 minutes, stirring occasionally, until the glaze thickens and clings to the ribs.

Step 5: Rest and Serve

Transfer the glazed ribs to a serving platter and let them rest for 5 minutes. This allows the glaze to set slightly and the juices to redistribute, ensuring each bite is moist and flavorful.

Serve warm, with extra glaze spooned over the top if desired. The ribs should have a sticky, caramelized exterior with meat that pulls cleanly from the bone. Pair with a crisp green salad or roasted vegetables to balance the richness.

Make-Ahead Tips for This Recipe

Prep Ahead Strategy

Mix your glaze ingredients the night before—I combine 0.75 cup ketchup, 0.5 cup brown sugar, and all spices in a jar. This lets flavors meld overnight in the fridge. Just whisk in 2 tbsp vinegar before using.

Rib Prep Shortcut

Cut and season your 2.5 lb ribs up to 24 hours ahead. Store them uncovered on a tray in the fridge. This dries the surface, which helps achieve a better sear when you’re ready to cook. 💡

Pressure Cook in Advance

Cook the ribs completely through pressure cooking, then cool and refrigerate in their liquid for up to 2 days. When ready to serve, reheat in the Instant Pot on “Sauté” and add fresh glaze.

Glaze Storage

Extra glaze keeps in an airtight container for 1 week in the fridge. Reheat gently in the microwave with 1 tbsp water to restore its sheen. I often double the glaze recipe for leftovers.

Freezing Tips

Cooked ribs freeze beautifully for 3 months. Wrap individual portions in foil, then place in a freezer bag. Thaw overnight in the fridge before reheating with fresh glaze. ❄️

Reheating Method

For best results, reheat ribs in the Instant Pot with ¼ cup beef broth on “Sauté” for 5-7 minutes. Add glaze at the end to prevent burning. The microwave works in 1-minute bursts at 70% power.
