How to Make Spicy Jalapeno Chicken Stir-Fry with Sesame Seeds Recipe

Step 1: Coat the Chicken

Start by tossing the chicken pieces with cornstarch, kosher salt, and ground black pepper in a large bowl. This simple step creates a delicate crust that locks in moisture and gives you that slight crispiness when cooked. Make sure every piece gets an even coating, setting the stage for juicy, flavorful chicken.

Step 2: Prepare the Sauce

Next, combine water, soy sauce, light brown sugar, sesame oil, and minced garlic in a separate bowl. This sauce mixture is your flavor masterpiece, blending sweet, salty, nutty, and garlicky notes that will elevate the entire dish. Set this aside so the flavors marry beautifully while you cook.

Step 3: Sear the Chicken

Heat olive oil over medium-high heat in a large nonstick skillet until shimmering. Carefully add the chicken—work in batches if needed to avoid crowding—and cook each side for 2 to 3 minutes until nicely browned and cooked through. You’re aiming for an internal temperature of 165°F to ensure safety and tenderness. Once cooked, transfer the chicken to a plate and tent it to keep warm.

Step 4: Cook the Onions and Jalapenos

Using the same skillet, toss in the diced onions and sliced jalapenos. Their aromas will fill your kitchen as they soften, roughly 4 to 6 minutes. The jalapenos lend their vibrant heat while the onions mellow and add subtle sweetness—a perfect counterbalance.

Step 5: Combine Chicken and Sauce

Return the cooked chicken back to the skillet along with the sauce mixture. Stir everything together and continue to cook for 2 to 3 minutes so the sauce thickens slightly and clings to each morsel. This final step ensures that your Spicy Jalapeno Chicken Stir-Fry with Sesame Seeds Recipe has that irresistible glaze and cohesive flavor.

Garnishes

Side Dishes

While this stir-fry shines on its own over a bed of fluffy white rice, you can jazz it up with a side of steamed veggies like broccoli or snap peas for extra color and nutrients. A light cucumber salad can provide a refreshing, cooling element against the spicy heat.

Creative Ways to Present

For a fun presentation, serve your Spicy Jalapeno Chicken Stir-Fry with Sesame Seeds Recipe in lettuce cups for a handheld twist. Alternatively, plating it over cauliflower rice is a clever low-carb swap that keeps all the bold flavors intact. No matter how you present it, your guests are sure to be impressed!

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer your leftovers to an airtight container and refrigerate for up to 3 days. Keeping the stir-fry chilled ensures the chicken stays tender and the flavors remain vibrant for your next meal.

Freezing

This dish freezes well, making it a perfect batch-cooking candidate. Pack portions into freezer-safe containers and freeze for up to 2 months. When you’re ready, thaw overnight in the fridge for best results.

Reheating

Reheat gently in a skillet over medium heat to maintain the texture and warmth of the chicken without drying it out. Stir occasionally until heated through, then sprinkle fresh sesame seeds again to refresh the crunch and aroma.

FAQs

Can I use chicken breast instead of thighs?

Absolutely! While chicken thighs keep the dish juicier, chicken breast works fine — just be careful not to overcook it, as breast meat can dry out more easily.

How spicy is this dish?

The heat comes from fresh jalapenos, so it has a noticeable but manageable kick. You can remove the seeds to mellow the spice or add more peppers if you like it fiery.

Can I substitute soy sauce with a gluten-free option?

Yes, using tamari or a gluten-free soy sauce replacement works great here and won’t compromise the delicious umami flavor.

Is this recipe suitable for meal prep?

Definitely! It reheats well, making it ideal for lunches or dinners throughout the week with minimal effort.

What other garnishes can I add?

Try chopped cilantro, sliced green onions, or a drizzle of sriracha for extra freshness, color, and heat. Each adds a delightful layer to the dish.
