This slow cooker peanut chicken has been my go-to for nights when I want something both comforting and quick to assemble. I first stumbled on this combination on a rainy Sunday when the fridge offered only a few staples and a jar of peanut butter. The magic happened when the peanuts met soy and a touch of honey, producing a rich, slightly sweet sauce that clings to tender chicken. The texture is mellow and comforting, with soft cooked peppers and onions folded into a velvety sauce. My kids like it served over rice, and it has become the 'easy dinner that tastes special' whenever we need one. I learned to trust the slow cooker for this dish because it allows the chicken to remain moist while the sauce develops depth without babysitting. Cooking on LOW for a few hours transforms plain chicken breasts into something almost shreddable and perfectly infused with peanut aroma. The finishing touch of lime juice and chopped cilantro brightens the whole pot and prevents the sauce from feeling too heavy. This recipe is forgiving—use creamy or crunchy peanut butter depending on preference, and adjust the chili garlic paste to control heat.

Ingredients

• Chicken: 1.5 lb boneless skinless chicken breasts. Choose even-thickness breasts so they cook uniformly. If breasts are very thick, halve them horizontally for faster, even cooking.
• Vegetables: 1 red bell pepper, diced, and 1/2 large yellow onion, diced. The pepper adds sweetness and color while the onion melts into the sauce and adds body.
• Aromatics: 2 garlic cloves, chopped. Fresh garlic gives the best lift; use pre-minced only in a pinch.
• Peanut base: 1/2 cup creamy peanut butter. Creamy yields the smoothest sauce; crunchy works too if you like texture, but aim for a brand with minimal additives.
• Liquid: 1/2 cup chicken broth to loosen the peanut butter into a pourable sauce. Use low-sodium broth if watching salt.
• Savory-salty: 1/4 cup soy sauce. Regular or reduced-sodium depending on taste; tamari or coconut aminos can make it gluten-free.
• Sweetener: 1 tbsp honey. Balances the savory notes and softens the peanut taste.
• Finishing oils and heat: 1 tsp sesame oil and 1 tsp chili garlic paste. Sesame oil adds toasty aroma; chili garlic paste brings controlled heat and depth.
• Bright finish: 1 tbsp lime juice and 2 tbsp chopped cilantro. Added at the end to preserve freshness and color.

Instructions

Layer the vegetables: Place the diced red bell pepper and yellow onion in the bottom of the slow cooker, then scatter the chopped garlic on top. This creates a flavor bed so the chicken isn’t sitting directly against the hot pot, helping distribute aromatics as it cooks. Arrange the chicken: Set the 1.5 lb chicken breasts over the vegetables in a single layer. If breasts overlap, they will still cook but rotate them halfway through if possible for even results. Make the sauce: In a bowl or glass measuring cup, whisk together 1/2 cup 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. The warm broth helps dissolve the peanut butter for a glossy sauce; whisk vigorously to avoid lumps. Combine and cook: Pour the sauce over the chicken so it coats the breasts and trickles into the vegetables. Cover and cook on HIGH for 2 to 3 hours or on LOW for 4 to 5 hours. Chicken is done when it reaches 165°F in the thickest part and is easy to shred with forks; timing varies slightly by slow cooker model. Finish with brightness: Remove the lid and stir in 1 tbsp lime juice and 2 tbsp chopped cilantro. The acid prevents the sauce from feeling flat and wakes up all the flavors. Taste and adjust salt or heat if needed before serving.

Storage Tips

Store cooled portions in airtight containers in the refrigerator for 3 to 4 days. For freezing, portion into single-meal containers and leave a little headroom for expansion; label with the date and use within 3 months for best quality. To reheat, thaw overnight in the refrigerator and warm gently on the stovetop over low heat, stirring frequently and adding up to 2 tbsp water or broth per cup of sauce if it has thickened. Avoid microwaving straight from frozen to prevent uneven heating; if microwaving, cover and use short intervals, stirring between cycles.

Ingredient Substitutions

To make this gluten-free, replace soy sauce with tamari or coconut aminos at a 1:1 ratio. For a lower-sodium version, choose low-sodium soy and low-sodium chicken broth. Use natural peanut butter but add an extra tablespoon of honey to balance the earthiness if the natural nut butter is more intense. If someone has a peanut allergy, almond or sunflower seed butter can work—expect a different but still pleasing flavor profile. For a vegetarian version, substitute firm tofu or seitan and vegetable broth, keeping in mind tofu benefits from pressing first to reduce water.

Serving Suggestions

Serve over steamed jasmine or basmati rice to soak up the sauce, or try rice noodles for an extra-textured dish. Garnish with extra chopped cilantro, thinly sliced green onions, and a wedge of lime on the side. For crunch, sprinkle toasted peanuts or sesame seeds just before serving. Pair with a crisp cucumber salad or quick pickled carrots to add acidity and contrast; a side of steamed broccoli or bok choy balances the richness of the sauce and rounds out the meal.

Cultural Background

Peanut-based sauces are common across many cuisines from West Africa to Southeast Asia. This particular flavor profile draws from Southeast Asian satay influences—a balance of sweet, salty, nutty, and sour. While not an authentic representation of any single traditional sauce, the marriage of peanut and soy in a slow-cooked format creates a comforting hybrid that nods to those culinary traditions. Over time, home cooks have adapted those influences to suit local ingredients and preferences, which is how dishes like this evolve into weeknight favorites.

Seasonal Adaptations

In summer, brighten the bowl with fresh herbs like mint or basil in addition to cilantro and add a side salad of seasonal vegetables. During colder months, swap the red pepper for roasted winter squash or add more onions for body. For holidays, scale up the recipe and add toasted sesame and chopped peanuts right before serving for a festive touch. A small splash of orange juice can add seasonal citrus notes during winter months when limes are less sweet.

Meal Prep Tips

Double the sauce and chicken for an efficient meal prep session; cool and portion into microwave-safe containers with rice for grab-and-go lunches. Keep garnishes like cilantro, lime wedges, and peanuts separate to maintain texture and color. If preparing in advance, wait to add lime juice until reheating to preserve brightness. Label containers with reheating instructions: reheat covered at medium-low heat and stir in a tablespoon of water if the sauce thickened during cooling.
