Spicy Hunan Chicken

Spicy Hunan Chicken is a quick stir-fry made with tender chicken, crisp vegetables, fresh chiles, garlic, ginger, and a savory sauce with plenty of heat. The sauce is lighter and less sweet than many takeout-style stir-fries, allowing the chile, soy, and aromatic flavors to stay prominent.

This version uses boneless chicken thighs for juicy results and a hot skillet for fast cooking. A short 15-minute marinade seasons the chicken before it hits the pan, and the entire dish is ready in under an hour.

Why This Recipe Works

• Chicken thighs stay juicy over high heat. Their slightly higher fat content makes them well suited to fast stir-frying.
• A short marinade seasons the meat throughout. Soy sauce, cornstarch, and oil add flavor while helping the chicken develop a lightly browned exterior.
• Fresh chiles provide clean, direct heat. Their flavor stays brighter than relying entirely on bottled hot sauce.
• The vegetables cook in stages. Firmer broccoli goes into the pan before the peppers so both stay crisp-tender rather than becoming soft.
• Cornstarch gives the sauce just enough body. It creates a glossy coating that clings to the chicken without becoming thick or heavy.

Equipment Needed

• 12-inch wok or large heavy skillet
• Medium mixing bowl
• Small mixing bowl
• Whisk
• Sharp chef's knife
• Cutting board
• Heatproof spatula or wooden spoon

Ingredients List

For the Chicken and Marinade

• 1½ pounds (680 g) boneless, skinless chicken thighs, cut into 1-inch pieces
• 1 tablespoon (15 mL) low-sodium soy sauce
• 1 tablespoon (15 mL) Shaoxing wine or dry sherry
• 2 teaspoons (6 g) cornstarch
• 1 teaspoon (5 mL) neutral cooking oil

For the Hunan-Style Sauce

• 3 tablespoons (45 mL) low-sodium soy sauce
• 1 tablespoon (15 mL) rice vinegar
• 1 tablespoon (15 mL) Shaoxing wine or dry sherry
• 2 teaspoons (10 mL) chili garlic sauce
• 1 teaspoon (4 g) granulated sugar
• 1 teaspoon (3 g) cornstarch
• ⅓ cup (80 mL) low-sodium chicken broth

For the Stir-Fry

• 2 tablespoons (30 mL) neutral cooking oil, divided
• 2 cups (180 g) broccoli florets, cut into bite-size pieces
• 1 medium red bell pepper (about 150 g), thinly sliced
• 1 medium green bell pepper (about 150 g), thinly sliced
• 2 fresh Fresno or red jalapeño chiles (about 30 g), thinly sliced
• 4 medium garlic cloves (about 12 g), minced
• 1 tablespoon (8 g) fresh ginger, finely grated
• 4 medium scallions (about 40 g), cut into 1-inch pieces, white and green parts separated

Optional Garnish

• 1 teaspoon (3 g) toasted sesame seeds, optional
• 2 tablespoons (6 g) sliced scallion greens, optional

Ingredient Notes and Substitutions

• Chicken Thighs: Boneless, skinless thighs stay moist during high-heat cooking and have enough flavor to stand up to the spicy sauce. Boneless chicken breast can be substituted, but it cooks faster and can become dry if overcooked.
• Fresh Chiles: Fresno chiles provide moderate heat and a slightly fruity flavor. Red jalapeños or serrano peppers can be substituted. Serranos are generally hotter, so adjust the amount according to your preferred spice level.
• Shaoxing Wine: Shaoxing wine contributes depth and a subtle fermented aroma. Dry sherry is the most practical substitute. If avoiding alcohol, use additional chicken broth, though the finished sauce will have less complexity.
• Chili Garlic Sauce: Chili garlic sauce brings heat, garlic flavor, and acidity. Sambal oelek can be substituted, but the sauce will taste slightly less garlicky. Because brands vary in heat and saltiness, adjust to taste.
• Broccoli and Bell Peppers: These vegetables provide contrasting textures and color. Snow peas, sliced zucchini, or mushrooms can replace part of the vegetables, but very watery vegetables may release extra liquid and thin the sauce.

Step-by-Step Instructions

1. Marinate the Chicken

Place the chicken pieces in a medium bowl.

Add the soy sauce, Shaoxing wine, cornstarch, and neutral oil.

Toss until every piece is lightly coated, then let the chicken stand for 15 minutes while you prepare the vegetables and sauce.

The coating should look thin and slightly glossy rather than wet or pasty.

2. Mix the Sauce

In a small bowl, whisk together the soy sauce, rice vinegar, Shaoxing wine, chili garlic sauce, sugar, cornstarch, and chicken broth.

Whisk until the cornstarch is fully dissolved.

Set the sauce near the stove and stir it again immediately before using.

3. Prepare the Vegetables

Cut the broccoli into small, evenly sized florets.

Slice both bell peppers and the fresh chiles.

Mince the garlic, grate the ginger, and separate the white and green portions of the scallions.

Have everything ready before heating the wok because the stir-fry cooks quickly.

4. Sear the Chicken

Heat a wok or large skillet over high heat until very hot.

Add 1 tablespoon (15 mL) of the neutral oil and swirl to coat the surface.

Add the chicken in a single layer.

Cook without moving it for about 2 minutes, then stir-fry for another 3–4 minutes until browned and nearly cooked through.

Transfer the chicken to a clean plate.

5. Cook the Broccoli

Return the wok to medium-high heat.

Add the remaining 1 tablespoon (15 mL) oil followed by the broccoli.

Stir-fry for about 2 minutes.

The broccoli should turn bright green but still feel firm.

6. Add the Peppers and Aromatics

Add the red bell pepper, green bell pepper, fresh chiles, garlic, ginger, and scallion whites.

Stir-fry for another 2 minutes.

The peppers should soften slightly while retaining some crispness, and the garlic and ginger should smell fragrant without browning deeply.

7. Return the Chicken

Add the cooked chicken and any juices from the plate back to the wok.

Toss with the vegetables for about 1 minute.

Check a larger piece of chicken with an instant-read thermometer. It should reach 165°F (74°C) before serving.

8. Add the Sauce

Stir the prepared sauce again, then pour it around the edges of the hot wok.

Toss continuously for 1–2 minutes.

The sauce should bubble quickly, become glossy, and lightly coat the chicken and vegetables.

If it becomes too thick, add 1–2 tablespoons (15–30 mL) water or chicken broth.

9. Finish the Stir-Fry

Add the scallion greens and toss for about 30 seconds.

Remove the pan from the heat.

The vegetables should remain colorful and crisp-tender, and there should be enough sauce to coat everything without pooling heavily in the bottom of the pan.

10. Garnish and Serve

Transfer the Spicy Hunan Chicken to a serving dish.

Sprinkle with the optional sesame seeds and additional scallion greens.

Serve immediately while the chicken is hot and the vegetables retain their texture.

Tips for Success

• Prepare everything before turning on the heat. Stir-frying moves quickly, so there is little time to chop ingredients once cooking starts.
• Use a very hot pan for the chicken. High heat encourages browning instead of steaming.
• Do not overcrowd the skillet. If your pan is smaller than 12 inches, cook the chicken in two batches.
• Adjust the fresh chiles to your heat preference. Remove some or all of the seeds for a milder dish, or use serranos for more heat.
• Keep the vegetables slightly crisp. They continue cooking briefly after the sauce is added.
• Add the sauce only at the end. Cornstarch-thickened sauces can become overly thick if simmered for too long.

Storage, Freezing, and Make-Ahead Instructions

• Refrigeration: Cool leftovers slightly, then transfer them to an airtight container. Refrigerate within 2 hours and store for up to 3–4 days. The vegetables will gradually soften during storage, so the dish is at its best within the first 2 days.
• Freezing: The cooked chicken and sauce can be frozen, although the bell peppers and broccoli will become softer after thawing. Transfer completely cooled portions to freezer-safe containers and freeze for up to 2 months.
• Thawing and Reheating: Thaw frozen Hunan Chicken overnight in the refrigerator. Reheat in a skillet over medium heat with 1–2 tablespoons (15–30 mL) water or chicken broth until steaming hot and the chicken reaches 165°F (74°C) . Avoid prolonged reheating, which can dry out the chicken and soften the vegetables further.
• Make-Ahead Preparation: Cut the chicken and vegetables up to 1 day ahead and refrigerate them separately. The sauce can also be mixed up to 2 days ahead and refrigerated in a covered container. Marinate the chicken for only about 15 minutes shortly before cooking rather than leaving it in the soy-based marinade overnight.

FAQ

How spicy is Spicy Hunan Chicken?

This version has noticeable heat from fresh chiles and chili garlic sauce. For a milder dish, use one chile, remove the seeds, and reduce the chili garlic sauce to 1 teaspoon.

Can I use chicken breast instead of thighs?

Yes. Cut boneless, skinless chicken breast into uniform pieces and cook just until it reaches 165°F (74°C). Breast meat is leaner and can dry out more quickly than thighs.

Why is my Hunan Chicken watery?

The pan may not have been hot enough, the vegetables may have released excess moisture, or the sauce may not have simmered long enough for the cornstarch to activate. Keep the heat fairly high and cook the sauce until it becomes glossy.

Can I add different vegetables?

Yes. Snow peas, mushrooms, zucchini, baby corn, or sliced carrots can be used. Add firmer vegetables earlier and quick-cooking vegetables later so everything finishes at the same time.

Can I make Spicy Hunan Chicken ahead of time?

You can prepare the chicken, vegetables, and sauce in advance, but the stir-fry has the best texture when cooked shortly before serving. Fully cooked leftovers can be refrigerated for up to 3–4 days.
