Instant Pot Sweet and Sour Spare Ribs Recipe: Tangy Vinegar-Kissed Tenderness in 60 Minutes

This Instant Pot sweet and sour spare ribs recipe delivers tender, fall-off-the-bone meat with a perfectly balanced tangy-sweet glaze—all in just 60 minutes. The pressure cooker transforms tough ribs into melt-in-your-mouth perfection while the vinegar-kissed sauce adds a bright, restaurant-quality finish.

I’ve tested this method dozens of times, and it consistently delivers results that rival your favorite BBQ joint.

The secret lies in a two-step process: first, a high-heat sear in the Instant Pot to lock in flavors, followed by a pressure cook that breaks down the connective tissue without drying the meat.

The sauce—made with apple cider vinegar, brown sugar, and a touch of ginger—cuts through the richness while enhancing the natural sweetness of the ribs. No need for marinating overnight; this method works with just 30 minutes of prep before cooking.

What you’ll end up with is juicy, tender ribs glistening with a glossy, caramelized glaze that’s tangy yet sweet, with just the right amount of heat. The sauce clings to every bite, making each mouthful a harmonious blend of textures and flavors.

This recipe is foolproof and works for beginners or seasoned cooks alike—just follow the steps, and you’ll have a showstopping main course ready in under an hour.

Serve these ribs with steamed rice or crusty bread to soak up every last drop of that luscious sauce. The leftovers reheat beautifully, too, so you can enjoy this dish for days. Let’s get cooking—your taste buds will thank you.

Ingredients for instant pot sweet sour spare ribs

Fourteen ingredients, sixty minutes, melt-in-your-mouth ribs with a tangy-sweet glaze that rivals your favorite BBQ joint.

The ribs are the star here, so don’t skimp on quality. Costco or your local butcher shop are great places to find fresh, bone-in spare ribs—look for cuts with good marbling and a vibrant pink color. If you can’t find bone-in, bone-in ribs develop more flavor during the pressure cook, but meat-only cuts will still work. Trim any thick fat deposits before searing to ensure even cooking. I always buy a few extra ribs—leftovers reheat beautifully, and the sauce is even better the next day once the flavors meld. For the apple cider vinegar, Bragg is my go-to because it’s pasteurized but still packs a punch without being harsh.

No Bragg apple cider vinegar? White vinegar or rice vinegar works in a pinch, but you’ll need to add an extra tablespoon of sugar to balance the flavor. The soy sauce can be swapped for coconut aminos if you’re avoiding sodium. For the ginger, frozen works if you’re in a rush, but fresh is ideal—just grate it while it’s still frozen to avoid mess. The sesame oil adds depth, but if you’re avoiding it, a dash of toasted sesame seeds sprinkled on top at the end gives a similar nutty aroma. The cornstarch is key for thickening the sauce—don’t substitute flour, or the sauce will turn cloudy. If you’re short on time, you can use arrowroot powder instead at the same ratio.

Store leftover ribs in an airtight container in the fridge for up to 4 days, or freeze for 3 months. The sauce keeps well too—just reheat it separately if you’re not using it all at once. For serving, I like to arrange the ribs on a platter, drizzle with extra sauce, and scatter sliced red bell pepper and green onions on top. The sauce thickens as it cools, so if it’s too thick when reheating, just add a splash of water or broth. These ribs are perfect for meal prep—portion them into containers with a side of rice or steamed veggies for easy lunches all week.

Step-by-step instructions for sweet and sour spare ribs

Here’s how to transform tough ribs into fall-off-the-bone tenderness with a glossy, tangy glaze.

Pat the 2.5 lb spare ribs completely dry with paper towels—this is crucial for that perfect caramelized crust. Heat a large skillet over medium-high heat and add the 1 tablespoon vegetable oil. Once shimmering, add the ribs in a single layer and sear for 3-4 minutes per side until they develop deep golden-brown spots.

Here’s the thing—don’t crowd the pan. If your ribs don’t fit in one layer, work in batches to ensure even browning. The Maillard reaction happening here creates the deep, savory foundation for your sweet-sour sauce. Once seared, transfer the ribs to your Instant Pot using tongs to avoid losing that precious crust.

In the same skillet (no need to clean it—the browned bits are flavor gold), reduce heat to medium and add the 1 tablespoon finely grated fresh ginger and 4 cloves minced garlic cloves. Sauté for just 30 seconds until fragrant—ginger burns quickly, so watch closely. Pour in the 0.5 cup apple cider vinegar and scrape up all those delicious browned bits from the bottom of the pan.

Let the vinegar simmer for 2 minutes until reduced by half, then add the 0.5 cup brown sugar and 0.25 cup honey. Stir constantly for 1-2 minutes until the sugar dissolves completely and the mixture begins to thicken slightly. This is where the magic happens—the balance of sweet and tangy begins to develop right before your eyes.

Pour the sauce mixture over the seared ribs in your Instant Pot. Add the 0.25 cup low-sodium soy sauce, 1 tablespoon toasted sesame oil, 1 tablespoon diamond crystal kosher salt, and 1 teaspoon freshly ground black pepper. Stir gently to coat the ribs evenly with the sauce.

Secure the lid and set the Instant Pot to high pressure for 45 minutes. The ribs should be fork-tender when done—you’ll know they’re ready when they easily pull apart at the bone. If you’re using a pressure cooker without a keep-warm setting, transfer the ribs to a plate and tent loosely with foil while you prepare the sauce thickening.

While the ribs pressure cook, prepare the sauce thickening by mixing the 1 tablespoon cornstarch with 2 tablespoons water in a small bowl until smooth. Once the ribs are done, carefully release the pressure and remove the ribs, reserving the cooking liquid in the pot.

Return the pot to the stovetop over medium heat and add the cornstarch slurry. Stir constantly for 2-3 minutes until the sauce thickens to a glossy, syrupy consistency that coats the back of a spoon. The sauce should be thick enough to cling to the ribs but still pour gracefully. Taste and adjust seasoning if needed—you might want to add a splash more apple cider vinegar for extra tang.

Slice the 1 whole red bell pepper into thin strips and slice the 4 whole green onions diagonally. Arrange the ribs on a serving platter and generously drizzle with the thickened sauce. Garnish with the bell pepper strips and green onions for freshness and color contrast.

Here’s where it gets fun—serve immediately while the ribs are steaming hot. The sauce should be sticky and glossy, perfectly balancing sweet, tangy, and savory flavors. Each bite should deliver that melt-in-your-mouth tenderness you’ve been promised, with the sauce clinging beautifully to every piece of meat. Don’t forget to save some sauce for dipping—it’s that good.

Pro cooking tips for perfect results

Sear Like a Pro

That initial sear is where 90% of the flavor develops, so don’t rush it. I use a 12-inch cast-iron skillet (like Lodge) because it retains heat beautifully—heat it until a drop of water dances on the surface.

Pat those ribs bone-dry with paper towels before searing, or they’ll steam instead of brown. Work in batches if needed, but never overcrowd—you want those ribs to sizzle and develop a deep mahogany crust. 🔥

Sauce Science

The secret to balancing sweet and tangy lies in the reduction timing. When you add the apple cider vinegar, let it simmer until it’s reduced by half—this intensifies the acidity without making the sauce harsh.

I always taste-test after adding the brown sugar and honey: the sauce should taste bright and balanced, not cloyingly sweet. If it’s too sweet, add 1 extra tablespoon of vinegar; if it’s too tart, stir in ½ teaspoon more honey.

Pressure Cook Precision

Set your Instant Pot to high pressure for exactly 45 minutes—no more, no less. The ribs need that time to break down, but overcooking will turn them mushy. After pressure releases, let them rest for 10 minutes before slicing.

This resting time lets the juices redistribute, ensuring every bite is juicy and tender. Pro tip: Use a meat thermometer to check the internal temp—it should read 203°F at the thickest part.

Sauce Thickening Tricks

Cornstarch is your best friend here, but timing is everything. Whisk it with cold water first to avoid lumps, then stir vigorously into the hot cooking liquid. Keep the heat at medium-low while thickening—too high, and the sauce will cook into a gluey mess.

For extra shine, finish with ½ teaspoon toasted sesame oil right before serving. The sauce should coat the back of a spoon but still pour like honey. ✨

Garnish for Impact

Don’t skip the fresh garnishes—they elevate the dish instantly. Thinly slice the red bell pepper into ¼-inch strips and cut the green onions at a 45-degree angle for maximum visual appeal. The pepper adds a crunchy contrast, while the onions bring a bright, fresh finish.
