Ingredients for Mandarin Orange Chicken Recipe Slow Cooker
Tender chicken thighs and bright citrus come together for this vibrant, hands-off dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Skinless Chicken Thighs 🍗 | 1 ½ lb | Trimmed of excess fat |
| Mandarin Orange Segments 🍊 | 1 cup | Canned or fresh, drained |
| Mandarin Orange Juice 💧 | ½ cup | Reserved from can or fresh |
| Soy Sauce 🫒 | ⅓ cup | Low-sodium preferred |
| Brown Sugar 🍚 | ¼ cup | Light or dark variety |
| Rice Vinegar 🍶 | 2 tbsp | Or apple cider vinegar |
| Fresh Garlic 🧄 | 3 cloves | Minced finely |
| Fresh Ginger 🌿 | 1 tbsp | Grated or minced |
| Cornstarch 🌾 | 2 tbsp | For thickening sauce |
| Water 💧 | ¼ cup | For cornstarch slurry |
| Red Pepper Flakes 🌶️ | ¼ tsp | Optional for heat |
| Sesame Oil 🫒 | 1 tsp | Toasted variety preferred |
| Green Onions 🧅 | 3 whole | Thinly sliced for garnish |
| Sesame Seeds 🌾 | 1 tbsp | Toasted for garnish |
The chicken thighs are non-negotiable here—bone-in, skin-on won’t work in the slow cooker (trust me, I’ve tried). Costco or Sam’s Club have great bulk options for boneless, skinless. Look for vibrant orange segments in the canned aisle—avoid the ones packed in heavy syrup. Fresh mandarins work too, but you’ll need about 6-8 to get a cup of juice and segments.
No mandarin oranges? Clementines or tangerines are perfect substitutes. Low-sodium soy sauce is key—regular can make the dish too salty. Rice vinegar adds the right tang, but apple cider vinegar works in a pinch. The cornstarch slurry is essential for that glossy, restaurant-style sauce thickness.
Leftovers keep 4-5 days in the fridge and actually taste better after a day. Freeze for up to 3 months (the sauce may separate slightly, but it comes back together when reheated). Garnish with green onions and sesame seeds just before serving.

Step-by-Step Instructions for Mandarin Orange Chicken Slow Cooker
This hands-off method delivers tender chicken in a glossy citrus sauce with minimal effort.
Step 1: Prepare and Season the Chicken
Trim the 1.5 lb boneless skinless chicken thighs of excess fat and place them in the slow cooker. I arrange them in a single layer to ensure even cooking and better sauce absorption. This step prevents the chicken from steaming in its own juices.
In a bowl, whisk together the 0.33 cup soy sauce, 0.25 cup brown sugar, 2 tbsp rice vinegar, minced 3 cloves fresh garlic, 1 tbsp fresh ginger, 0.5 cup mandarin orange juice, 1 tsp sesame oil, and 0.25 tsp red pepper flakes. Pour this mixture over the chicken.
Step 2: Slow Cook Until Tender
Cover the slow cooker and cook on low for 4-5 hours or high for 2-2.5 hours. You’ll know it’s ready when the chicken shreds easily with a fork and reaches an internal temperature of 165°F.
About 30 minutes before serving, add the 1 cup mandarin orange segments to the slow cooker. This timing prevents them from turning mushy while still allowing them to absorb the flavors of the sauce.
Step 3: Thicken the Sauce
Transfer the chicken to a serving platter, leaving the sauce in the slow cooker. In a small bowl, mix the 2 tbsp cornstarch with the 0.25 cup water until smooth. Stir this slurry into the sauce in the slow cooker.
Cover and cook on high for an additional 10-15 minutes, stirring occasionally, until the sauce thickens to a glossy consistency that coats the back of a spoon. The cornstarch activates in the heat, transforming the thin liquid into a rich, velvety sauce.
Step 4: Garnish and Serve
Return the chicken to the slow cooker and toss gently to coat in the thickened sauce. The chicken should glisten with a sticky, slightly tangy glaze that clings to every piece.
Transfer to a serving dish and garnish with the thinly sliced 3 whole green onions and 1 tbsp sesame seeds. The green onions add a fresh, crisp contrast, while the sesame seeds provide a nutty crunch. Serve immediately over steamed rice or noodles to soak up every last bit of the flavorful sauce.
Pro Tips For Making Mandarin Orange Chicken Recipe Slow Cooker
- Brown the Thighs: Sear the chicken thighs in a hot pan for 2-3 minutes per side before adding to the slow cooker. I learned this the hard way—without browning, the flavor stays flat even with all that orange juice and soy sauce.
- Drain the Oranges: Pat the mandarin segments dry and reserve the juice separately. Sounds weird, but it works: it keeps the sauce from getting watery while still packing that citrus punch.
- Skip the Overcrowding: Arrange the chicken in a single layer at the bottom of the slow cooker, even if it means using a larger one. After burning three batches, I finally figured out that stacking leads to uneven cooking and mushy texture.
- Thicken at the End: Transfer the cooked chicken out, then simmer the sauce on the stovetop with a cornstarch slurry for 3-4 minutes. My grandmother swore by this, and she was right: it turns the thin liquid into a glossy glaze that clings to every bite.
Essential Equipment for mandarin orange chicken recipe slow cooker
Slow Cooker Selection
I swear by my 6-quart Crock-Pot for this recipe—it’s the perfect size for 1.5 lb chicken thighs with room for sauce expansion. A programmable model with a timer is ideal, but any basic slow cooker works. Avoid those tiny 2-quart ones; they’ll overflow with this volume. 🔥
Essential Tools
A good whisk is non-negotiable for blending the sauce ingredients smoothly. I use my OXO Good Grips one daily. You’ll also need a small bowl for the cornstarch slurry—any heatproof bowl from your kitchen will do.
Measuring Accurately
Precise measurements make this dish shine. Use liquid measuring cups for the orange juice and soy sauce, and dry measuring cups for the brown sugar and cornstarch. A fine mesh strainer helps when draining canned mandarins.
Serving Essentials
Have a large serving spoon ready for the saucy chicken and a rice cooker going simultaneously. I love my Zojirushi for perfect rice every time. A microplane makes quick work of the fresh ginger.
Optional Upgrades
For easier cleanup, line your slow cooker with slow cooker liners—Reynolds Kitchens makes great ones. A meat thermometer ensures your chicken hits 165°F perfectly. These small investments save time and hassle.
Garnish Like a Pro
Keep kitchen shears handy for snipping green onions quickly. A small dry skillet toasts sesame seeds in 2 minutes for extra flavor. These finishing touches elevate the dish from good to restaurant-worthy. ✨

Frequently Asked Questions
Can I use chicken breasts instead of thighs?
You can, but thighs stay juicier during slow cooking. If using breasts, reduce cooking time to 3-4 hours on low to prevent dryness. Thighs are more forgiving and absorb the citrus flavor better.
How do I make the sauce thicker?
Mix 1 tbsp cornstarch with 2 tbsp cold water and stir into the sauce. Cook on high for 10 minutes until glossy. Avoid adding too much cornstarch or the sauce may become gel-like.
Can I prepare this ahead of time?
Combine all ingredients except chicken in the slow cooker insert the night before. Store covered in the fridge, then add chicken and cook as directed in the morning.
What if my sauce is too sweet?
Balance it with 1 tbsp rice vinegar or a splash of soy sauce. Taste and adjust gradually, as the flavors deepen during cooking. The citrus should be bright, not cloying.
