2. Ingredients

For the Slow Cooker Kung Pao Chicken:

• 2 pounds (900g) boneless, skinless chicken thighs, cut into 1-inch cubes
• 1 red bell pepper, cut into 1-inch pieces
• 1 green bell pepper, cut into 1-inch pieces
• 1/2 cup (75g) white onion, roughly chopped
• 3 cloves garlic, minced
• 1 tablespoon (15g) fresh ginger, grated
• 8-10 dried red chili peppers (adjust for heat preference)
• 1/2 cup (65g) unsalted roasted peanuts
• 1/4 cup (30g) water chestnuts, drained and sliced
• 3 green onions, sliced for garnish

For the sauce:

• 1/3 cup (80ml) low-sodium soy sauce
• 3 tablespoons (45ml) rice vinegar
• 2 tablespoons (30ml) hoisin sauce
• 2 tablespoons (30g) brown sugar
• 1 tablespoon (15ml) sesame oil
• 1 tablespoon (15g) cornstarch mixed with 2 tablespoons water (for thickening)

The chicken thighs are recommended for their tenderness in slow cooking, while authentic dried chili peppers provide the signature Kung Pao heat. For a milder version, remove the seeds from the dried chilies before cooking.

3. Pro Tips

To make the most flavorful Slow Cooker Kung Pao Chicken, don’t skip browning the chicken before adding it to the slow cooker. This quick extra step creates a beautiful caramelization that adds depth to the entire dish. Heat a tablespoon of oil in a skillet over medium-high heat and brown the chicken pieces in batches for 2-3 minutes. This seals in moisture and creates a flavor foundation that slow cooking alone can’t achieve.

Control the spice level by adjusting how you prepare the dried chilies. For maximum heat, cut them in half to expose the seeds. For moderate heat, leave them whole but slightly crushed. For mild flavor with minimal spice, simply leave them whole and remove them before serving – they’ll impart their distinctive flavor without overwhelming heat.

Add vegetables strategically for perfect texture. While the chicken cooks for hours, bell peppers and water chestnuts need only 30-45 minutes. Adding them too early results in mushy vegetables. For the best texture contrast in your Slow Cooker Kung Pao Chicken, add these crunchy elements during the final cooking stage, about 30 minutes before serving.

4. Instructions

Step 1

In a small bowl, whisk together the soy sauce, rice vinegar, hoisin sauce, brown sugar, and sesame oil until the sugar dissolves completely. This sauce base will infuse your Slow Cooker Kung Pao Chicken with its signature flavor. Set aside while preparing the other ingredients.

Step 2

Heat 1 tablespoon of oil in a large skillet over medium-high heat. Working in batches to avoid overcrowding, brown the chicken pieces for about 2 minutes per side until they develop a golden exterior. You’re not cooking them through—just creating flavor through caramelization. Transfer the browned chicken to your slow cooker.

Step 3

Add the minced garlic, grated ginger, and dried chili peppers to the slow cooker with the chicken. Pour the prepared sauce over everything, ensuring the chicken is well-coated. Cover and cook on low for 3-4 hours or on high for 1.5-2 hours, until the chicken is tender but not falling apart.

Step 4

When there’s about 30 minutes of cooking time remaining, stir in the bell peppers and water chestnuts. This timing preserves their texture while allowing them to absorb the sauce flavors. Replace the lid and continue cooking for the remaining time.

Step 5

Just before serving, create a slurry by mixing 1 tablespoon cornstarch with 2 tablespoons water until smooth. Set the slow cooker to high, add the slurry, and stir gently. Cover and cook for 10-15 minutes until the sauce has thickened to a glossy consistency that beautifully coats your Slow Cooker Kung Pao Chicken.

Step 6

Stir in the roasted peanuts, saving some for garnish if desired. Serve your Slow Cooker Kung Pao Chicken over steamed rice, garnished with sliced green onions and the reserved peanuts for that authentic presentation and perfect textural finish.

5. Variations

For a lower-carb Crockpot Kung Pao Chicken alternative, serve over cauliflower rice instead of traditional white rice. The cauliflower soaks up the delicious sauce while keeping the meal lighter and veggie-focused. You can also add extra vegetables like zucchini, mushrooms, or snap peas during the last 30 minutes of cooking for additional nutrition and texture.

Create a Spicy Kung Pao Chicken Slow Cooker version by doubling the dried chilies and adding 1-2 teaspoons of chili garlic sauce to the sauce mixture. This variation brings serious heat that true spice lovers will appreciate. On the other hand, for a family-friendly adaptation, reduce the chilies to just 2-3 whole peppers and add an extra tablespoon of brown sugar to balance the remaining heat with sweetness.

For a vegetarian twist, substitute the chicken with 2 pounds of extra-firm tofu, pressed and cubed, or use a mix of mushrooms and tofu for a meatier texture. The slow cooking method still works beautifully, though you’ll want to reduce the cooking time to about 2 hours on low to maintain the tofu’s texture.

6. Storage and Serving

Slow Cooker Kung Pao Chicken stores beautifully, actually improving in flavor overnight as the ingredients continue to meld. Refrigerate leftovers in an airtight container for up to 3 days. For longer storage, freeze portions in freezer-safe containers for up to 2 months. When reheating, add a splash of water or chicken broth to restore the sauce’s consistency, and consider adding fresh peanuts for renewed crunch.

For an impressive presentation, serve your Slow Cooker Kung Pao Chicken in a large shallow bowl over steamed jasmine rice. Create a beautiful color contrast by arranging steamed broccoli florets around the edge. For a complete Chinese feast, pair with simple side dishes like cucumber salad dressed with rice vinegar and sesame oil, or quick-fried green beans with garlic.

Transform leftovers into exciting new meals by using the Slow Cooker Kung Pao Chicken as filling for lettuce wraps, topping for rice bowls, or stuffing for baked potatoes. The versatility of this dish extends well beyond its initial serving, making it perfect for meal prep and reducing food waste.

7. FAQs

Can I use chicken breasts instead of thighs for Slow Cooker Kung Pao Chicken?
Yes, you can substitute chicken breasts, but they tend to dry out more easily in slow cooking. If using breasts, reduce the cooking time by about 30 minutes and check for doneness earlier.

How can I make my Kung Pao Chicken more or less spicy?
Adjust the heat by changing the number and preparation of dried chilies. For milder flavor, use fewer whole chilies. For more heat, cut or crush the chilies to release their seeds and oils.

Can I add the vegetables at the beginning with the chicken?
For the best texture, add bell peppers and water chestnuts during the last 30 minutes of cooking. Adding them earlier will result in overly soft vegetables that lose their appealing crunch.

What if I don’t have hoisin sauce?
You can create a substitute by mixing 1 tablespoon soy sauce, 1 teaspoon peanut butter, 1/2 teaspoon honey, splash of vinegar, and pinch of garlic powder.

Is this Slow Cooker Kung Pao Chicken gluten-free?
Not as written, but it’s easily adapted by using tamari instead of soy sauce and checking that your hoisin sauce is gluten-free (or making your own gluten-free version).
