Ingredients

For this Skinny Slow Cooker Kung Pao Chicken, you’ll need:

• 1½ pounds (680g) boneless, skinless chicken breasts, cut into 1-inch cubes
• 1 red bell pepper, diced into 1-inch pieces
• 1 green bell pepper, diced into 1-inch pieces
• ½ cup (75g) white onion, roughly chopped
• 3 cloves garlic, minced
• 1 tablespoon fresh ginger, grated
• ½ cup (120ml) low-sodium chicken broth
• ¼ cup (60ml) reduced-sodium soy sauce
• 2 tablespoons rice vinegar
• 2 tablespoons honey (or substitute with 1 tablespoon brown sugar)
• 1 tablespoon tomato paste
• 1-2 teaspoons chili garlic sauce (adjust according to heat preference)
• 2 tablespoons cornstarch
• 2 tablespoons water
• ⅓ cup (40g) unsalted peanuts, roasted
• 4 green onions, sliced (for garnish)
• Brown rice or cauliflower rice, for serving (optional)

The reduced-sodium soy sauce is crucial for keeping this dish “skinny” while still providing that essential umami flavor. The chili garlic sauce can be adjusted to your personal spice tolerance without compromising the authentic Kung Pao character.

Pro Tips

Achieving perfect Skinny Slow Cooker Kung Pao Chicken relies on a few critical techniques:

First, resist the urge to peek and stir during cooking. Every time you lift the lid, you release heat and extend cooking time by 15-20 minutes. Trust your slow cooker to do its job—the chicken will become tender and flavorful without your intervention.

Second, add the cornstarch slurry only during the final 30 minutes of cooking. Adding it too early will prevent it from properly thickening the sauce. For best results, mix the cornstarch with cold water until completely smooth before adding to ensure a silky sauce without lumps.

Finally, wait until the very end to add the peanuts and bell peppers. The peppers should be added during the last 30 minutes alongside the cornstarch slurry to maintain their vibrant color and slight crunch. Adding peanuts just before serving preserves their crunch—a signature element of authentic Kung Pao chicken. If added too early, they’ll become soggy and lose their textural contrast.

Instructions

Step 1

Place the cubed chicken breasts at the bottom of your slow cooker. In a medium bowl, combine the chicken broth, soy sauce, rice vinegar, honey, tomato paste, minced garlic, grated ginger, and chili garlic sauce. Whisk until well combined, then pour this mixture over the chicken, ensuring all pieces are coated.

Step 2

Cover the slow cooker and set it to cook on LOW for 3-4 hours or on HIGH for 1.5-2 hours. The chicken should be tender but not overcooked. Remember, chicken breasts cook faster than thighs, so check for doneness at the minimum time suggested.

Step 3

When approximately 30 minutes of cooking time remains, prepare your cornstarch slurry by combining the cornstarch and cold water in a small bowl, stirring until completely smooth. Pour this mixture into the slow cooker and gently stir to incorporate.

Step 4

Add the diced red and green bell peppers and chopped onion to the slow cooker. Stir gently to combine, then cover and continue cooking for the remaining 30 minutes. This timing allows the vegetables to soften slightly while maintaining their vibrant color and some texture.

Step 5

Once cooking is complete, give everything a good stir. The sauce should have thickened to a glossy consistency that coats the chicken and vegetables. If you prefer a thicker sauce, you can create and add a bit more cornstarch slurry.

Step 6

Just before serving your Skinny Slow Cooker Kung Pao Chicken, fold in the roasted peanuts and sprinkle with sliced green onions. Serve over brown rice or cauliflower rice for an extra nutritious meal that satisfies your Chinese takeout cravings without the guilt.

Variations

Vegetarian Kung Pao: Transform this Skinny Slow Cooker Kung Pao Chicken into a meat-free delight by substituting the chicken with extra-firm tofu (pressed and cubed) or a combination of mushrooms and chickpeas. Reduce the cooking time to 1-2 hours on LOW since these alternatives don’t need as much time to tenderize. The sauce works beautifully with these plant-based proteins while maintaining the dish’s signature flavors.

Spicy Kung Pao Chicken: For heat enthusiasts, amp up the signature Kung Pao spiciness by adding 4-6 dried red chilis (with seeds removed) to the slow cooker along with the chicken. You can also increase the chili garlic sauce to 1 tablespoon and add ½ teaspoon of crushed red pepper flakes. This variation maintains the “skinny” aspect while delivering a more authentic fiery kick that Kung Pao is known for.

Nutty Vegetable Kung Pao: Enhance the nutritional profile by adding more vegetables like sliced water chestnuts, bamboo shoots, zucchini cubes, or baby corn during the last 30 minutes of cooking. For an alternative to peanuts, try using cashews or a combination of nuts for varied texture and flavor while keeping the protein content high.

Storage and Serving

Your Skinny Slow Cooker Kung Pao Chicken will keep well in an airtight container in the refrigerator for up to 4 days. The flavors actually develop and improve overnight, making this an excellent meal prep option. When reheating, add a splash of water or chicken broth to maintain moisture, and heat gently in the microwave or on the stovetop until just warmed through to prevent the chicken from becoming tough.

For freezing, cool the chicken completely before transferring to freezer-safe containers, leaving out the peanuts (add fresh ones when serving). It will maintain quality for up to 3 months. Thaw overnight in the refrigerator before reheating.

Serve this vibrant dish over brown rice for a wholesome dinner, or try cauliflower rice for an ultra-low-carb option. For a complete Chinese takeout experience at home, pair with a simple side of steamed broccoli or a fresh cucumber salad dressed with rice vinegar and a touch of sesame oil. For entertaining, serve family-style with small bowls of extra peanuts, sliced green onions, and chili oil as customizable toppings.

FAQs

Can I use chicken thighs instead of chicken breasts?
Absolutely! Boneless, skinless chicken thighs work wonderfully in this Skinny Slow Cooker Kung Pao Chicken and often result in even more tender meat. Adjust cooking time to 4-5 hours on LOW or 2-3 hours on HIGH as thighs take slightly longer to cook but are more forgiving and less likely to dry out.

How can I make this dish gluten-free?
Simply substitute the soy sauce with tamari or coconut aminos. Double-check that your chili garlic sauce is gluten-free, as some brands may contain wheat-based ingredients.

Can I make this in an Instant Pot instead?
Yes! Use the sauté function to brown the chicken pieces first (optional but adds flavor), then add all ingredients except cornstarch slurry, bell peppers, and peanuts. Cook on high pressure for 8 minutes with a quick release, then add the cornstarch slurry and bell peppers using the sauté function for about 5 minutes until thickened.

Is this recipe truly “skinny”?
Yes, compared to restaurant versions that can contain up to 1,000 calories per serving, this recipe reduces calories by using less oil, reducing sugar, incorporating leaner protein, and controlling portion sizes while maintaining authentic flavors.

How spicy is this dish?
With the recommended amount of chili garlic sauce, it has a mild-to-medium heat level. You can easily adjust by reducing the chili garlic sauce to 1 teaspoon for a milder version or increasing up to 1 tablespoon for a spicier kick.

Conclusion

This Skinny Slow Cooker Kung Pao Chicken is comfort food at its finest — a guilt-free celebration of bold flavors that proves healthy eating doesn’t mean sacrificing satisfaction. It’s the kind of dish that makes weeknight dinners feel special while keeping your nutrition goals on track. The slow cooker not only makes preparation practically effortless but allows the complex flavors to develop into something truly restaurant-worthy.
