Ingredients You Need

Chicken

2 to 2.5 pounds boneless skinless chicken breasts or thighs, cut into 1-inch pieces
- Thighs stay extra juicy and forgiving in the slow cooker.
- Use breasts if you prefer leaner meat and shorter cook time.

Sauce

1/2 cup low sodium soy sauce
- Use tamari or coconut aminos for gluten free.
1/4 cup rice vinegar
- Seasoned rice vinegar adds a tiny bit of sweetness.
1/4 cup hoisin sauce
- I like Lee Kum Kee or Kikkoman; they taste consistent and balanced.
3 tablespoons honey or brown sugar
- Honey gives a cleaner sweetness, brown sugar adds a deeper caramel note.
2 tablespoons ketchup
- Pantry shortcut that adds body and tang without extra work.
2 tablespoons cornstarch
- Thickens the sauce at the end.
1/2 cup low sodium chicken broth
- Use water in a pinch, but broth gives better flavor.
3 to 4 cloves garlic, minced
1 tablespoon fresh ginger, minced or grated
- Use 1 teaspoon ground ginger if you need a shortcut.
1 to 2 tablespoons chili garlic sauce or sambal oelek
- Adjust to your spice tolerance. Start with 1 tablespoon if you feel cautious.
1 teaspoon toasted sesame oil
- Adds that classic takeout aroma; a little goes a long way.

Veggies and Crunch

1 red bell pepper, cut into 1-inch chunks
1 green bell pepper, cut into 1-inch chunks
1 small yellow onion, cut into 1-inch chunks
1/2 to 3/4 cup roasted unsalted peanuts
- Use cashews if you prefer a milder, buttery crunch.
3 to 4 green onions, sliced, for garnish
Toasted sesame seeds, optional garnish

Pantry Shortcuts

Pre-minced garlic and ginger from a jar save time on busy nights.
Frozen bell pepper strips work if you do not have fresh peppers.
Use a bottled Kung Pao or stir fry sauce in place of the homemade sauce if you need a super fast dump-and-go option, then adjust sweetness and heat at the end.

Equipment

4 to 6 quart slow cooker or crockpot
Cutting board and sharp knife
Measuring cups and spoons
Small bowl and whisk for the sauce
Wooden spoon or spatula
Small saucepan (optional, if you want to thicken sauce on the stove)

Quick Tips & substitutions

Cut chicken into even 1-inch pieces so everything cooks at the same rate.
Use chicken thighs if you worry about overcooking; they stay tender longer.
Start with less chili garlic sauce, then add more at the end if you want extra heat.
Swap soy sauce with tamari or coconut aminos for a gluten free version.
Use cashews instead of peanuts if you need a peanut free option.
Stir in frozen bell peppers during the last 45 minutes so they stay crisp-tender.
Thicken the sauce with cornstarch only after the chicken finishes cooking to avoid clumps.
Taste the sauce before serving and adjust with a splash of vinegar for brightness or honey for sweetness.
Line the slow cooker with a slow cooker liner if you want easier cleanup.
Double the sauce ingredients if you like extra saucy Kung Pao chicken over rice or noodles.

How to Make Crockpot Kung Pao Chicken Recipe

Step 1: Prep the Chicken and Veggies

Cut the chicken into 1-inch cubes and place them in the bottom of the slow cooker. Chop the bell peppers and onion into similar sized chunks so they cook evenly. Set the veggies aside for now so the chicken cooks through first.

Step 2: Mix the Sauce

In a medium bowl, whisk together soy sauce, rice vinegar, hoisin sauce, honey or brown sugar, ketchup, chicken broth, garlic, ginger, chili garlic sauce, and sesame oil. Taste a small spoonful and adjust sweetness or heat to your preference. The sauce should taste slightly stronger than you want the final dish, since it will mellow as it cooks.

Step 3: Add Sauce to the Crockpot

Pour the sauce over the chicken in the slow cooker. Stir gently so every piece of chicken gets coated. Cover the crockpot with the lid.

Step 4: Slow Cook the Chicken

Cook on low for 3 to 4 hours or on high for 1.5 to 2 hours. Check at the earliest time mark, since every slow cooker runs a little differently. The chicken should feel tender and reach 165°F in the center.

Step 5: Add Veggies

Once the chicken turns opaque and nearly done, add the chopped bell peppers and onion to the crockpot. Stir them into the sauce and chicken. Cook on high for another 30 to 45 minutes until the veggies turn crisp-tender.

Step 6: Thicken the Sauce

In a small bowl, whisk the cornstarch with 3 tablespoons of cold water until smooth. Stir this slurry into the hot sauce in the crockpot. Cook on high for 15 to 20 minutes, stirring once or twice, until the sauce thickens and coats the chicken and veggies.

Step 7: Add Peanuts and Finish

Stir in the peanuts right before serving so they keep some crunch. Taste the Kung Pao chicken and adjust seasoning with a pinch of salt, extra chili garlic sauce, or a drizzle of honey. Top with sliced green onions and sesame seeds.

Step 8: Serve

Spoon the Crockpot Kung Pao Chicken over hot rice, cauliflower rice, or noodles. Make sure each bowl gets plenty of sauce, veggies, and peanuts. Serve hot and enjoy that slow cooker takeout magic.

Recipe Variations

Gluten free: Use tamari or certified gluten free soy sauce and a gluten free hoisin sauce.
Lower carb: Serve over cauliflower rice or zucchini noodles and reduce the honey or sugar to 1 tablespoon.
Peanut free: Swap peanuts with roasted cashews or sunflower seeds.
Extra veggies: Add broccoli florets, snap peas, or mushrooms during the last 30 to 45 minutes.
Extra spicy: Add dried red chili peppers or a drizzle of chili oil at the end.
Mild version: Cut the chili garlic sauce in half and add more honey for a sweeter sauce.
Vegan: Use extra firm tofu or tempeh instead of chicken, use vegetable broth, and choose vegan hoisin.

Ways to Serve Crockpot Kung Pao Chicken Recipe

Spoon over steamed jasmine rice or brown rice.
Serve with cauliflower rice for a lighter bowl.
Toss with cooked lo mein or spaghetti noodles for Kung Pao noodles.
Pair with stir fried green beans or steamed broccoli on the side.
Use leftovers in lettuce wraps with extra green onions and crunchy veggies.

Storage Success

Store leftover Crockpot Kung Pao Chicken in an airtight container in the fridge for up to 4 days. The flavors deepen overnight, so it tastes even better the next day. Reheat gently on the stovetop over medium heat or in the microwave, and add a splash of water or broth if the sauce thickens too much. Freeze portions in freezer-safe containers for up to 2 months, then thaw in the fridge and reheat for an easy future dinner.
