Ingredients You’ll Need

Chicken and Veggies

2 pounds boneless skinless chicken breasts, cut into 1-inch chunks
- Use thighs if you like richer flavor and extra tenderness.
1 red bell pepper, chopped into 1-inch pieces
1 green bell pepper, chopped into 1-inch pieces
1 small yellow onion, chopped
3 green onions, sliced (white and green parts separated)
3 garlic cloves, minced
1 tablespoon fresh ginger, minced or grated
- Use 1 teaspoon ground ginger if you keep that in your pantry.

Sauce Ingredients

1/2 cup low sodium soy sauce
- Use tamari or coconut aminos for a gluten friendly option.
1/3 cup hoisin sauce
- I like Lee Kum Kee or Kikkoman hoisin for consistent flavor.
1/4 cup rice vinegar
1/4 cup water or low sodium chicken broth
3 tablespoons brown sugar, packed
- Use honey or maple syrup if you avoid refined sugar.
1 to 2 tablespoons sambal oelek or chili garlic sauce
- Use 1 tablespoon for mild heat, 2 or more for spicy.
1 tablespoon toasted sesame oil
1 teaspoon crushed red pepper flakes
- Skip or reduce if you cook for kids or spice sensitive eaters.

Thickener

3 tablespoons cornstarch
3 tablespoons cold water

Nuts and Garnish

3/4 cup roasted unsalted peanuts
- Use cashews if you prefer a softer crunch.
Extra sliced green onions for topping
Sesame seeds for garnish (optional)

Pantry Shortcuts & Substitutions

Use pre-minced garlic and ginger from jars if you want to save chopping time.
Use frozen stir fry veggies instead of fresh peppers and onions. Add them in the last hour so they stay crisp.
Use a bottled Kung Pao or stir fry sauce in place of the homemade sauce if you need a super fast prep. Taste and adjust sweetness and heat.

Equipment List

4 to 6 quart slow cooker or Crockpot
Cutting board and sharp knife
Small mixing bowl for sauce
Whisk or fork
Measuring cups and spoons
Small bowl for cornstarch slurry
Tongs or large spoon for stirring and serving

Tips & Tricks

Cut the chicken into even pieces so everything cooks at the same rate.
Spray the slow cooker insert with cooking spray to make cleanup easier.
Mix the sauce in a separate bowl so the sugar dissolves and the flavors blend before you pour it over the chicken.
Start with less chili sauce and red pepper flakes, then add more heat at the end if you want.
Add the peanuts near the end of cooking so they stay crunchy and do not turn soggy.
Stir the cornstarch slurry well and add it while the sauce bubbles so it thickens smoothly.
Lift the lid as little as possible so the slow cooker keeps its heat and cooks on schedule.
Taste the sauce at the end and adjust with a splash of soy sauce, a pinch of sugar, or a bit more vinegar to balance salt, sweet, and tang.
Use chicken thighs if you plan to cook on low for the full 6 hours because they stay juicy.
Double the recipe in a large slow cooker and freeze half for easy future dinners.

How to Make Crockpot Kung Pao Chicken Recipe

Step 1: Prep the Chicken and Veggies

Chop the chicken into bite-size pieces and pat them dry with paper towels. This helps the sauce cling better and keeps extra moisture out of the slow cooker. Chop the bell peppers and onion into similar sized pieces so they cook evenly.

Slice the green onions and keep the white parts separate from the green tops. Mince the garlic and ginger or scoop them from jars if you use those shortcuts. Set everything aside so you can build the recipe quickly.

Step 2: Mix the Kung Pao Sauce

In a small bowl, add soy sauce, hoisin sauce, rice vinegar, water or broth, brown sugar, sambal oelek or chili garlic sauce, sesame oil, and red pepper flakes. Whisk until the sugar dissolves and the sauce looks smooth and glossy. Taste a tiny bit and adjust sweetness or heat to match your preference.

If you use a bottled stir fry sauce, pour it into a bowl and thin it with a little water or broth so it does not turn too thick in the slow cooker. Add extra garlic or ginger if you want a stronger punch. Keep the sauce near the slow cooker so you can pour it right over the chicken.

Step 3: Load the Crockpot

Spray the slow cooker insert with cooking spray. Add the chicken pieces in an even layer. Scatter the chopped onion, bell peppers, garlic, ginger, and the white parts of the green onions over the chicken.

Pour the Kung Pao sauce over everything and stir gently to coat the chicken and veggies. Make sure the chicken sits mostly under the sauce so it cooks evenly and stays juicy. Cover the slow cooker with the lid.

Step 4: Cook the Chicken

Cook on low for 4 to 6 hours or on high for 2 to 3 hours. The chicken turns tender and the veggies soften but still hold some bite. Stir once about halfway through cooking if you can, and push any exposed chicken back into the sauce.

Check a piece of chicken near the center of the slow cooker to make sure it looks cooked through and no pink remains. Taste the sauce and adjust seasoning with a splash of soy sauce or a pinch of sugar if needed. Keep the slow cooker on warm while you finish the last steps.

Step 5: Thicken the Sauce

In a small bowl, whisk the cornstarch and cold water until the mixture looks smooth with no lumps. Push the chicken and veggies to the sides of the slow cooker a bit to expose more liquid in the center. Pour the cornstarch slurry into the hot liquid while you stir.

Turn the slow cooker to high if it sits on low. Stir for a minute, then cover and cook for about 15 to 20 minutes. The sauce thickens and turns glossy and coats the chicken and veggies nicely.

Step 6: Add Peanuts and Finish

Stir in the peanuts and most of the sliced green onion tops. Save a little green onion for garnish. Let everything sit in the slow cooker on warm for about 5 minutes so the flavors mingle and the peanuts heat through.

Taste one more time and adjust the heat level with extra chili sauce or red pepper flakes if you like it spicier. Scoop the Crockpot Kung Pao Chicken into bowls or over rice. Garnish with the remaining green onions and sesame seeds.

What to Serve with Crockpot Kung Pao Chicken Recipe

Serve this Crockpot Kung Pao Chicken Recipe over steamed white rice, brown rice, or jasmine rice so the grains soak up that spicy, savory sauce. Cauliflower rice or stir fried cabbage works great if you want a lighter option. Add a side of steamed broccoli, snap peas, or baby bok choy to round out the meal with extra veggies.

You can also spoon the chicken into lettuce cups and top with extra peanuts and green onions for a fun, hand held dinner. A simple cucumber salad or Asian style slaw adds a cool, crunchy contrast to the warm, saucy chicken. Finish the meal with sliced oranges or pineapple for a fresh, sweet bite.

Storage Options

Store leftovers in an airtight container in the fridge for up to 4 days.
Cool the chicken completely, then freeze portions in freezer safe containers or bags for up to 3 months.
Reheat gently in a skillet over medium heat with a splash of water or broth until hot and bubbly.
Use the microwave in short bursts, stirring between each burst, and add a spoonful of water if the sauce looks too thick.
Add fresh green onions and a few new peanuts after reheating to bring back crunch and brightness.
