Ingredients & Substitutions
Chicken
I prefer boneless, skinless chicken thighs because they stay juicy and flavorful. However, chicken breasts work well if you want a leaner option.
Cornstarch
A light coating of cornstarch helps the chicken get crisp and golden when cooked.
The Sauce
This sauce brings everything together with the perfect balance of flavors:
- soy sauce
- water
- brown sugar
- sesame oil
- garlic
It’s sweet, salty, and ultra savory—better than takeout!
Jalapeño Peppers
The jalapeños add the signature kick. You control the heat level:
- Hotter: use older jalapeños with white marks on the skin and keep the seeds + ribs. Slice into rounds.
- Milder: remove the seeds and ribs before slicing the peppers.
Other Add-Ins
- diced onions
- sesame seeds for garnish
- cooked white rice for serving
How Spicy Is Jalapeño Chicken?
It’s totally up to you!
Keep the seeds for bold heat.
Remove them for a mild, family-friendly version.
You can even mix one hot pepper with one mild pepper if you want something in between.
Make-Ahead Tips
You can easily prep parts of this recipe:
- The sauce: Mix everything and refrigerate for up to 3 days.
- Chicken: Cut it into pieces and refrigerate 1–2 days before cooking.
This makes dinner even faster on busy nights.
How to Store Jalapeño Chicken
Store leftovers in an airtight container for 3–4 days in the refrigerator.
Note: the chicken may soften slightly as it sits. Reheat on the stovetop or in the microwave until warmed through.
