Ingredients You’ll Need
Chicken and Veggies
- 2 to 2 ½ pounds boneless skinless chicken breasts or thighs, cut into 1-inch pieces
- Thighs stay extra juicy in the slow cooker, while breasts taste leaner.
- 1 red bell pepper, chopped into 1-inch pieces
- 1 green bell pepper, chopped into 1-inch pieces
- 1 small yellow onion, chopped
- 3 to 4 green onions, sliced, white and green parts separated
- ½ cup roasted unsalted peanuts
- Use lightly salted peanuts and reduce added salt a bit.
Sauce Ingredients
- ½ cup low sodium soy sauce
- I like Kikkoman or a similar brand with simple ingredients.
- ¼ cup rice vinegar
- ¼ cup hoisin sauce
- This adds sweetness and depth; use gluten free hoisin if needed.
- 3 tablespoons honey or brown sugar
- Honey gives a glossy finish, brown sugar tastes more caramel-like.
- 2 tablespoons ketchup
- Pantry shortcut that adds tang and color without extra work.
- 2 to 3 tablespoons water or low sodium chicken broth
- 2 tablespoons cornstarch
- 1 to 2 tablespoons chili garlic sauce or sambal oelek
- Start with 1 tablespoon for mild heat, add more for a spicy kick.
- 2 teaspoons toasted sesame oil
- 3 cloves garlic, minced
- 1 tablespoon fresh ginger, minced or grated
- Use 1 teaspoon ground ginger if you do not have fresh, but fresh tastes brighter.
Optional Add-ins and Substitutions
- 1 cup chopped zucchini or broccoli florets for extra veggies
- 1 small can sliced water chestnuts, drained, for extra crunch
- Swap peanuts with cashews if you prefer a softer bite
- Use coconut aminos or tamari for a gluten friendly option and slightly sweeter flavor
Equipment
- 4 to 6 quart slow cooker or Crockpot
- Cutting board and sharp knife
- Small bowl and whisk for the sauce
- Measuring cups and spoons
- Skillet for optional browning of chicken or toasting peanuts
Tips & Tricks
- Cut the chicken into even pieces so everything cooks at the same rate.
- Use low sodium soy sauce so the sauce does not taste too salty after it reduces.
- Whisk the cornstarch with cold water or broth before adding it to avoid lumps.
- Add bell peppers in the last hour of cooking if you prefer them crisp-tender instead of very soft.
- Toast peanuts in a dry skillet for 2 to 3 minutes to deepen their flavor before adding.
- Start with less chili garlic sauce, then stir in more at the end if you want extra heat.
- Line the slow cooker with a reusable liner if you want easier cleanup.
- Stir the chicken once halfway through cooking so the sauce coats everything evenly.
- Thicken the sauce on the stovetop if it still looks thin at the end; simmer a few minutes until glossy.
- Serve over hot rice, noodles, or cauliflower rice so the sauce has something to soak into.
How to Make Crockpot Kung Pao Chicken
1: Prep the chicken and veggies
Pat the chicken dry with paper towels, then cut it into bite-size 1-inch cubes. Chop the bell peppers and onion into similar sized pieces so they cook evenly. Slice the green onions, keeping the white and green parts separate for cooking and garnish.
2: Mix the Kung Pao sauce
In a medium bowl, whisk soy sauce, rice vinegar, hoisin sauce, honey or brown sugar, ketchup, water or broth, cornstarch, chili garlic sauce, sesame oil, garlic, and ginger. Whisk until the cornstarch dissolves and the sauce looks smooth and slightly thick. Taste a small spoonful and adjust sweetness or heat to your preference.
3: Load the slow cooker
Place the chicken pieces in the bottom of the slow cooker. Add the chopped onion, bell peppers, and the white parts of the green onions. Pour the Kung Pao sauce over everything and stir gently so the sauce coats the chicken and veggies.
4: Cook low and slow
Cover the slow cooker with the lid and cook on low for 3 to 4 hours or on high for 1 ½ to 2 hours. Stir once about halfway through cooking so the sauce thickens evenly and the chicken cooks on all sides. Cook until the chicken feels tender and the sauce looks glossy and slightly thick.
5: Adjust thickness and flavor
If the sauce looks too thick, stir in 1 to 2 tablespoons of water or broth until it reaches your ideal consistency. If the sauce looks thin, mix 1 teaspoon cornstarch with 1 tablespoon cold water, then stir it into the slow cooker and cook 10 to 15 more minutes. Taste and add a splash of soy sauce for more salt, a drizzle of honey for more sweetness, or extra chili garlic sauce for more heat.
6: Add peanuts and finish
Stir in the peanuts and the green parts of the green onions right before serving so they keep their crunch and fresh flavor. If you use water chestnuts or extra veggies that you want crisp, add them in the last 20 to 30 minutes of cooking. Give everything a final stir so the sauce coats every piece of chicken and veggie.
What to Serve with Crockpot Kung Pao Chicken
Serve this Crockpot Kung Pao Chicken Recipe over fluffy white rice, brown rice, or cauliflower rice to soak up the sauce. Add a simple side like steamed broccoli, snap peas, or stir-fried green beans for extra veggies. A crisp cucumber salad with a light soy-sesame dressing balances the heat and richness. For a fun takeout-style spread, add veggie spring rolls, edamame, and sliced oranges for dessert.
