Lettuce cups have a way of making dinner feel lighter and more playful at the same time. Instead of a heavy bun or a mound of rice, you get a crisp, cool leaf cradling something warm, saucy, and deeply savory. The problem is that most lettuce cup fillings demand a hot skillet, constant stirring, and a watchful eye. That’s where the Instant Pot earns its place on the counter. With a pressure cooker, chicken thighs go from raw to tender in a fraction of the usual time, and the sauce reduces down to a glossy honey-sesame glaze with almost no effort. The result is a weeknight-friendly filling that tastes like it came from a takeout container, minus the grease and the wait.

This recipe for Instant Pot Honey Sesame Chicken Lettuce Cups is built around a simple idea: let the pressure cooker do the heavy lifting for the chicken, then finish the sauce on the sauté setting so it clings to every shred. The filling is sweet, salty, tangy, and nutty all at once, with a gentle hit of garlic and ginger in the background. It’s spooned into cool, sturdy lettuce leaves and topped with crunchy sesame seeds, sliced scallions, and a shower of fresh herbs. Serve it as a light main course, a party appetizer, or a build-your-own dinner where everyone assembles their own cups at the table. The whole thing comes together in well under an hour, and most of that time is hands-off.

Why This Recipe Works

Chicken thighs are the ideal cut for pressure cooking. They contain enough fat and connective tissue to stay juicy under high pressure, whereas lean chicken breast can turn stringy if it’s cooked even a minute too long. Boneless, skinless thighs are easy to find and shred beautifully with two forks or a quick pulse of a hand mixer.

The sauce is mixed directly in the pot before the chicken goes in, which means fewer dishes and better flavor distribution. Honey provides sweetness and body, soy sauce brings salinity and umami, rice vinegar cuts through the richness, and toasted sesame oil adds a nutty finish that ties everything together. A small amount of cornstarch slurry, whisked in after pressure cooking, thickens the sauce into a glaze that coats the chicken instead of pooling at the bottom of the lettuce leaf.

Finally, the lettuce itself matters. Butter lettuce, Bibb lettuce, and gem lettuce all have tender leaves with a sturdy enough rib to hold a generous spoonful of filling. Iceberg works in a pinch but tends to crack when folded. Either way, washing and drying the leaves thoroughly is essential—wet leaves make for a soggy cup.

Ingredients

For the chicken and sauce:

• 1½ pounds (680 g) boneless, skinless chicken thighs, trimmed of excess fat
• ⅓ cup (80 ml) low-sodium soy sauce
• ¼ cup (85 g) honey
• 2 tablespoons rice vinegar
• 1 tablespoon toasted sesame oil
• 1 tablespoon ketchup
• 3 cloves garlic, minced (about 1 tablespoon)
• 1 tablespoon freshly grated ginger
• ¼ teaspoon red pepper flakes, or to taste
• ¼ teaspoon freshly ground black pepper
• ½ cup (120 ml) low-sodium chicken broth or water
• 2 tablespoons cornstarch whisked with 3 tablespoons cold water (slurry)

For serving:

• 2 heads butter, Bibb, or gem lettuce, separated into individual leaves (about 16–20 leaves)
• 2 tablespoons toasted sesame seeds
• 3 scallions, thinly sliced on the bias
• ¼ cup chopped fresh cilantro or mint (optional)
• 1 small cucumber, thinly sliced (optional, for crunch)
• Lime wedges, for squeezing

Yield: Serves 4 as a main course or 6–8 as an appetizer.

Equipment

• 6-quart or 8-quart Instant Pot (or any electric pressure cooker)
• Measuring cups and spoons
• Small bowl for the cornstarch slurry
• Whisk
• Two forks or a hand mixer for shredding
• Large platter or serving bowl for the lettuce leaves
• Colander and clean kitchen towels for drying the lettuce

Preparation Instructions

1. Mix the sauce in the pot. Add the soy sauce, honey, rice vinegar, toasted sesame oil, ketchup, minced garlic, grated ginger, red pepper flakes, and black pepper to the inner pot of the Instant Pot. Whisk until the honey is fully dissolved and the mixture is uniform. Stir in the chicken broth.
2. Add the chicken. Nestle the trimmed chicken thighs into the sauce in a single layer, turning each piece once so it’s coated on both sides. The liquid should come about halfway up the chicken; it does not need to be fully submerged.
3. Pressure cook. Secure the lid and set the valve to sealing. Select Manual or Pressure Cook on High Pressure and set the timer for 10 minutes. It will take roughly 8–10 minutes for the pot to come to pressure.
4. Natural release. When the cooking time ends, allow the pressure to release naturally for 10 minutes, then carefully turn the valve to venting to release any remaining steam. Open the lid away from your face.
5. Shred the chicken. Transfer the chicken to a cutting board or shallow bowl using tongs. Shred it with two forks, or use a hand mixer on low speed for about 20–30 seconds to pull it apart quickly. Set aside.
6. Thicken the sauce. Press Sauté and set the pot to Normal. Bring the cooking liquid to a gentle simmer. Whisk the cornstarch slurry once more, then pour it into the pot in a steady stream while whisking constantly. Simmer for 2–4 minutes, whisking frequently, until the sauce thickens enough to coat the back of a spoon. It should look glossy and slightly syrupy.
7. Return the chicken. Add the shredded chicken back to the pot and toss until every piece is coated in the glaze. Taste and adjust: add a pinch of salt if needed, a squeeze of lime for brightness, or a few extra red pepper flakes for heat. Press Cancel to turn off the pot.
8. Prepare the lettuce. While the sauce simmers, separate the lettuce leaves, rinse them well, and spin or pat them completely dry. Arrange the leaves on a platter, overlapping slightly, with the cupped side facing up.
9. Assemble and serve. Spoon the warm chicken mixture into the lettuce leaves, filling each about two-thirds full. Sprinkle with toasted sesame seeds, sliced scallions, and fresh herbs. Add a cucumber slice to each cup if using, and serve immediately with lime wedges on the side.

Cooking Times and Temperatures at a Glance

• Pressure build: 8–10 minutes
• High-pressure cook: 10 minutes
• Natural release: 10 minutes, then quick vent
• Sauté reduction: 2–4 minutes
• Total active time: About 20 minutes
• Total time: About 40–45 minutes

Tips for the Best Results

Don’t skip the natural release. Releasing pressure immediately after cooking can cause the chicken to seize up and become tough. Ten minutes of natural release lets the thighs finish cooking gently and stay tender.

Trim the chicken well. Large pieces of fat or connective tissue won’t break down fully in 10 minutes and can leave chewy bits in the filling. Take a minute to trim before cooking.

Thicken the sauce before adding the chicken back. If you return the shredded chicken first and then add the slurry, the chicken absorbs the sauce and the glaze becomes uneven. Reduce first, then fold in the meat.

Dry the lettuce thoroughly. A salad spinner is ideal, but patting each leaf with a clean kitchen towel works too. Any water left on the leaves will thin the sauce and make the cups messy to eat.

Toast your own sesame seeds if you can. Place them in a dry skillet over medium-low heat for 2–3 minutes, stirring often, until fragrant and lightly golden. The flavor is noticeably deeper than pre-toasted seeds.

Keep the filling warm. If you’re serving these as an appetizer, set the Instant Pot to Keep Warm and let guests spoon the filling into leaves themselves. The lettuce can sit on ice or in the refrigerator until the last moment.

Practical Substitutions

Chicken: Boneless, skinless chicken breasts can be substituted, but reduce the cook time to 8 minutes and use a full 10-minute natural release to prevent dryness. Shred gently.

Sweetener: Maple syrup or brown sugar can replace the honey in equal amounts. If using brown sugar, whisk well to dissolve before adding the chicken.

Soy sauce: Tamari or coconut aminos work for gluten-free needs. If using coconut aminos, reduce the honey slightly, as coconut aminos are sweeter than soy sauce.

Rice vinegar: Apple cider vinegar or white wine vinegar can stand in, though the flavor will be slightly sharper. Use 1½ tablespoons instead of 2.

Ketchup: Tomato paste thinned with a splash of water works, or omit it entirely and add an extra teaspoon of honey and a pinch of salt.

Lettuce: Iceberg, romaine hearts, or even thin strips of napa cabbage can hold the filling. Endive leaves make elegant, bite-sized appetizer cups.

Add-ins: Finely diced water chestnuts, shredded carrots, or chopped cashews can be folded into the filling after cooking for extra texture.

Storage and Reheating Guidance

Store the chicken filling separately from the lettuce. The filling keeps in an airtight container in the refrigerator for up to 4 days. Lettuce leaves should be washed, dried, and stored in a sealed container lined with paper towels for up to 5 days.

To reheat, warm the filling gently in a skillet over medium-low heat with a splash of water or broth, stirring until heated through, about 3–4 minutes. Microwaving works too, but cover the container and stir halfway through to prevent the sauce from drying out. Avoid reheating the filling more than once.

The filling freezes well for up to 2 months. Thaw overnight in the refrigerator, then reheat on the stovetop, adding a tablespoon or two of water if the sauce has thickened too much. Fresh lettuce and toppings should always be prepared just before serving.
