Your Complete Cooking Timeline
Step 1: Toss the chicken cubes in that bowl with fish sauce and cornstarch. Make sure every piece gets a nice coating. This little step is gonna bring the tender pull.
Step 2: Heat ½ tablespoon oil in your pressure cooker on saut6#xE9; mode. Once hot, lay the chicken in a single layer so it can brown evenly. Sear for about 5-7 minutes until it6#x2019;s cooked through and gets nice golden color. Then take it out and set aside.
Step 3: Add the rest of the oil back into the pot. Toss in garlic, ginger, and that chopped red chili pepper if you like spicy. Saut6#xE9; for about a minute until you catch that fragrant smell.
Step 4: Add your colorful bell peppers to the pot. Cook for 3-4 minutes stirring a bit, you want them slightly tender but still crisp for texture contrast.
Step 5: Return the browned chicken cubes to the pot. Pour in the fresh pineapple chunks and stir everything together.
Step 6: Add the Thai sweet chili sauce on top and stir well to combine. Close the lid, set the valve to sealing, and cook on high pressure just 2 minutes. When done, quick release the pressure so you keep the peppers crisp and pineapple fresh tasting.
Valve Hacks You Need to Know
- If you hear the valve hiss before cooking, that means your pot is reaching pressure so get ready to time your cooking right.
- Use quick release for stir fries so veggies stay crisp instead of mushy from longer steam cooking.
- When saut6#xE9;ing, keep an eye on the float valve6#x2014;it should stay down so you know the pot6#x2019;s not sealing yet.
- Don6#x2019;t open the lid too soon after cooking, wait till float valve drops to avoid steam burns.
- If you want extra sauce thickening, release pressure and then use saut6#xE9; mode to reduce sauce a bit at the end.

Your Leftover Strategy Guide

- Reheat Tips: Use your pressure cooker6#x2019;s saut6#xE9; setting or microwave, but be sure not to overcook so chicken stays tender and peppers keep crunch.
Your Most Asked Questions Answered
- Can I use chicken thighs instead of breasts? Sure! Thighs work great because they6#x2019;re juicy, but gotta reduce cooking time a bit since they6#x2019;re more tender.
- What if I don6#x2019;t have fresh pineapple? You can use canned pineapple chunks, just drain most juice so stew doesn6#x2019;t get watery.
- Is fish sauce necessary? Fish sauce adds depth but if you can6#x2019;t find it, soy sauce or tamari is an okay substitute.
- Can I skip the chili pepper? Yeah, skip or reduce for less heat. The sweet chili sauce keeps the flavor balance.
- How do I keep peppers crisp? Quick pressure cook and quick release is key, avoid long steam time.
- Can I double the recipe? Yep, just make sure not to overcrowd the pot when browning chicken so it sears properly.
