Ingredients

Main Ingredients

• 1 1/2 lbs chicken thighs
• 1/4 cup soy sauce
• 1/4 cup hoisin sauce
• 2 tbsp rice vinegar
• 1 tsp crushed red pepper flakes
• 1/2 cup peanuts
• 2 bell peppers, sliced

Optional Kitchen Equipment

• Crockpot / slow cooker
• Mixing bowl
• Knife and cutting board
• Wooden spoon or spatula
• Measuring cups and spoons

Preparation Method

Step 1: Prepare the Chicken

Trim any excess fat from the chicken thighs and cut them into bite-sized pieces for even cooking and easy serving.

Step 2: Mix the Sauce

In a small bowl, combine the soy sauce, hoisin sauce, rice vinegar, and crushed red pepper flakes. Whisk until well combined. Taste and adjust the spice level according to preference.

Step 3: Combine in the Crockpot

Place the chicken pieces in the crockpot and pour the sauce mixture over the top. Stir to coat all the chicken evenly.

Step 4: Add Peanuts and Bell Peppers

Add the peanuts and sliced bell peppers to the crockpot. Gently fold them into the chicken and sauce, ensuring even distribution.

Step 5: Cook

Cover the crockpot and cook on low for 4–5 hours or on high for 2–3 hours, until the chicken is fully cooked and tender. The sauce should thicken slightly and coat the chicken and vegetables.

Step 6: Serve

Stir the chicken and sauce before serving to ensure everything is evenly coated. Serve hot over steamed rice, quinoa, or noodles. Garnish with extra peanuts or sliced green onions if desired.

Tips for Success

Use Chicken Thighs

Chicken thighs are ideal for slow cooking because they stay tender and juicy, unlike chicken breasts, which can dry out.

Adjust Spice Level

Crushed red pepper flakes can be reduced or increased depending on your heat preference. For a milder version, start with 1/2 tsp and adjust gradually.

Avoid Overcooking Vegetables

If you prefer bell peppers to stay slightly crisp, add them in the last 30–60 minutes of cooking rather than at the beginning.

Thickening the Sauce

If you prefer a thicker sauce, mix 1 tsp cornstarch with 1 tbsp water and stir into the crockpot 15 minutes before the end of cooking.

Make Ahead

This dish can be prepared the night before; just store the chicken and sauce mixture in the refrigerator and cook the next day.

Variations

Add Vegetables

Include broccoli, snap peas, or carrots for more color, flavor, and nutrition. Add them in the last hour of cooking to maintain their texture.

Sweet and Spicy

Add 1–2 tablespoons of honey or brown sugar to the sauce for a slightly sweeter, caramelized flavor.

Gluten-Free

Use tamari instead of soy sauce to make this recipe gluten-free. Check the hoisin sauce label for gluten-free options.

Low-Sodium Version

Opt for low-sodium soy sauce and reduce the amount of hoisin sauce to manage salt levels.

Stir-Fry Alternative

If short on time, cook the chicken, peppers, and sauce in a skillet on the stove over medium heat for 15–20 minutes instead of using a crockpot.

Serving Suggestions

• Serve over steamed jasmine or basmati rice to soak up the flavorful sauce.
• Pair with stir-fried vegetables for a balanced meal.
• Serve with rice noodles or quinoa for a different texture and nutrient profile.
• Garnish with chopped green onions, sesame seeds, or extra peanuts for a restaurant-style presentation.

Presentation Ideas

• Serve in a deep dish or bowl to keep the sauce contained.
• Add a side of lightly sautéed bok choy or snow peas for vibrant color.
• Drizzle extra hoisin sauce or sriracha on top for added flair.
