This Slow Cooker Peanut Chicken became one of those dishes I make when I want something comforting, hands-off, and reliably delicious. I first landed on this combination during a chaotic weeknight when I had little time but big expectations from hungry family members. The slow cooker turned simple ingredients—chicken breasts, a bell pepper, onion, garlic, and pantry peanut butter—into a silky sauce that clung to the meat and made even picky eaters ask for seconds. The texture of the chicken after several hours is fork-tender yet still meaty, while the sauce delivers a balance of savory soy, a touch of sweetness from honey, citrus brightness from lime, and a subtle heat from chili garlic paste. What I love most is how accessible the flavors are. The peanut butter gives a creamy mouthfeel and nutty backbone; soy sauce adds savory depth; sesame oil and cilantro bring that toasted, herbaceous finish. The diced red bell pepper and onion cook down into a sweet bed that picks up the sauce, so every bite has a little crunch or soft vegetal sweetness depending on how you serve it. It’s become a go-to for casual dinners, potlucks, or when I need a satisfying meal that can be plated over rice, noodles, or even greens.

Ingredients

• Chicken (1.5 lb): Use boneless, skinless chicken breasts for even cooking and easy shredding; choose firm, fresh breasts about 6–8 ounces each so they cook to tender perfection and absorb the sauce.
• Red bell pepper (1): Diced into 1/2-inch pieces, it adds sweet brightness and a pop of color; use a firm pepper without soft spots for the best texture after slow cooking.
• Yellow onion (1/2 large): Coarsely diced—this becomes meltingly sweet and forms a fragrant base under the chicken; Vidalia or sweet onions work well.
• Garlic (2 cloves): Roughly chopped; garlic infuses the sauce and prevents it from tasting flat—don’t skip it.
• Creamy peanut butter (1/2 cup): Natural or commercial brands work; pick one with minimal added sugar and salt for cleaner flavor. Crunchy can be used for extra texture.
• Chicken broth (1/2 cup): Use low-sodium so you can control the overall seasoning; it thins the peanut butter into a silky sauce.
• Soy sauce (1/4 cup): Regular or reduced-sodium adds umami; if gluten-free is needed use tamari.
• Honey (1 tbsp): Balances the savory elements with a subtle sweetness—agave or maple work as alternatives.
• Sesame oil (1 tsp): A little goes a long way to add toasted, nutty aroma.
• Chili garlic paste (1 tsp): Provides controlled heat; adjust to taste or substitute sriracha for smoother heat.
• Lime juice (1 tbsp): Stirred in after cooking for fresh acidity that brightens the sauce considerably.
• Cilantro (2 tbsp): Chopped and stirred in at the end for fragrant herbal lift; parsley can be used if you prefer.

Instructions

Prepare the base: Place the diced red bell pepper, diced half yellow onion, and chopped garlic in the bottom of the slow cooker. Spread them into an even layer—this creates a steaming bed so the chicken cooks evenly and picks up vegetal sweetness. No need to sauté first; the slow cooker will gently caramelize the onion. Layer the chicken: Arrange the 1.5 lb of chicken breasts on top of the vegetable bed in a single layer. Pat the breasts dry before placing them to help the sauce stick and to promote more consistent cooking. Overlapping is okay but try to distribute them evenly for uniform doneness. Make the sauce: In a bowl or a large measuring cup, whisk together 1/2 cup creamy peanut butter, 1/2 cup chicken broth, 1/4 cup soy sauce, 1 tbsp honey, 1 tsp sesame oil, and 1 tsp chili garlic paste until smooth. Warm the broth slightly if the peanut butter is stiff—this makes for a silkier emulsion. Taste and adjust salt or heat before pouring. Cook: Pour the prepared peanut sauce evenly over the chicken and vegetables so everything is coated. Cover and cook on HIGH for 2–3 hours or on LOW for 4–5 hours. The chicken is done when it reaches an internal temperature of 165°F and is easily pulled apart with two forks. If possible, avoid lifting the lid during the first half of cooking to maintain steady temperature. Finish and serve: Once cooked, remove the lid, stir in 1 tbsp fresh lime juice and 2 tbsp chopped cilantro. You can shred the chicken in the pot with two forks for pulled texture or slice whole breasts for plating. Serve warm over rice, noodles, or greens, and garnish with extra cilantro, sliced green onions, or crushed peanuts for crunch.

Storage Tips

Let leftovers cool to near room temperature before refrigerating to preserve texture. Transfer into shallow, airtight containers for faster cooling and even reheating. In the fridge the dish will keep 3–4 days; when freezing, portion into single-serving vacuum bags or heavy-duty containers and freeze up to 3 months. Reheat gently in a saucepan over low heat, adding a splash of broth to loosen the sauce, or microwave in 30-second bursts, stirring between intervals. Fresh cilantro and lime juice should be added after reheating to retain brightness.

Ingredient Substitutions

If you have peanut allergies, substitute 1/2 cup tahini (sesame paste) plus an extra tablespoon of honey to round the flavor, or use sunflower seed butter with a pinch more lime. For gluten-free, swap soy sauce for tamari or coconut aminos, but reduce sodium elsewhere if using regular soy. To lower calories, replace half the peanut butter with unsweetened Greek yogurt stirred in at the end for creaminess—wait until the pot is off heat so the yogurt doesn’t curdle. For extra veg, add carrots or snap peas in the last hour of cooking to keep them vibrant.

Serving Suggestions

Serve the chicken over steamed jasmine or brown rice for classic comfort; toss with rice noodles for a saucy noodle bowl, or spoon over a bed of mixed greens for a lighter option. Garnish with chopped cilantro, sliced scallions, extra lime wedges, and a sprinkle of crushed peanuts or toasted sesame seeds. For an elevated dinner, serve alongside quick-pickled cucumbers or a simple cabbage slaw to cut through the richness and add crunch.

Cultural Background

This dish is an Americanized, slow-cooker take on peanut-forward flavors found across Southeast Asia—most notably Indonesian and Thai cuisines where peanuts, lime, and chilies are common. While not a traditional satay or padang dish, it borrows the nutty-sweet-sour balance and adapts it to comfort-cooking methods popular in western kitchens. Slow cooking allows the flavors to meld in a way reminiscent of slow-simmered sauces in many regional home cooking traditions.

Seasonal Adaptations

In spring and summer, thin the sauce with extra lime and add fresh herbs like basil or mint for brightness; toss in raw tossed cucumbers or sliced snap peas at the end for crunch. In fall and winter, enrich the sauce with an extra tablespoon of peanut butter and roast root vegetables with the chicken for earthier flavors. Holiday gatherings welcome a spiced version—add 1/2 tsp ground ginger and a pinch of cinnamon for cozy depth that pairs well with roasted winter vegetables.

Meal Prep Tips

Divide the cooked chicken and sauce into single-serve containers with rice or noodles for grab-and-go lunches. Store the sauce separately if you want to maintain rice texture. If freezing, portion with rice in microwave-safe containers and thaw overnight in the fridge before reheating. Use sturdy, stackable containers and label with the date; rotate through within 3–4 days if refrigerated. This method saves evenings and ensures you always have a flavorful, balanced meal on hand.

Slow Cooker Peanut Chicken is one of those dependable dishes that rewards a little planning. It’s satisfying, easy to scale, and flexible enough to fit weeknight schedules or casual entertaining. Give it a try, tweak the heat and acid to your taste, and enjoy the kind of bowl that brings people together around the table.
