Ingredients You Need

Chicken

2 pounds boneless skinless chicken thighs, trimmed and cut into 1.5 inch pieces
- Thighs stay juicy and forgiving; use chicken breast if you prefer leaner meat and shorten cook time slightly.
1 teaspoon kosher salt
1 teaspoon black pepper
2 tablespoons cornstarch
- Toss with the chicken to help it brown slightly and thicken the sauce later.

Orange sauce

1 cup orange juice, pulp free
- Use 100 percent juice, not a “drink” or “cocktail.”
Zest of 1 large orange
- Fresh zest gives the strongest citrus flavor; avoid bottled zest.
1/3 cup low sodium soy sauce
- Use tamari or coconut aminos for gluten free.
1/3 cup honey
- You can swap with brown sugar if you prefer a deeper caramel note.
1/4 cup ketchup
- This adds body, color, and a subtle tang; any basic brand works.
2 tablespoons rice vinegar
- Use apple cider vinegar if you do not have rice vinegar.
2 tablespoons brown sugar, packed
- Adjust up or down to taste; I like a balance of sweet and tangy.
1 tablespoon fresh grated ginger
- Use 1 teaspoon ground ginger if you need a pantry shortcut.
3 cloves garlic, minced
- Jarred minced garlic works in a pinch, though fresh tastes brighter.
1/2 teaspoon red pepper flakes
- Add more for extra heat or skip for mild sauce.
1 tablespoon sesame oil
- Toasted sesame oil gives a restaurant-style flavor boost.

To thicken and finish

2 tablespoons cornstarch
3 tablespoons cold water
1 tablespoon orange marmalade, optional
- Adds extra orange punch and a glossy finish; use a good-quality brand with real peel.

Optional toppings

Sliced green onions
Toasted sesame seeds
Extra orange zest

Equipment list

4 to 6 quart slow cooker
Cutting board and sharp knife
Small whisk
Measuring cups and spoons
Small bowl for cornstarch slurry
Zester or microplane for the orange

Quick Tips & substitutions

Cut chicken pieces roughly the same size so they cook evenly and stay tender.
Pat chicken dry before you toss with cornstarch so the coating sticks well.
Use chicken thighs if you want juicy, forgiving meat and chicken breast if you prefer leaner protein and slightly shorter cook time.
Swap soy sauce with tamari or coconut aminos to keep the recipe gluten free.
Use 100 percent orange juice and fresh zest so the sauce tastes bright, not artificial.
Adjust sweetness by adding more honey or brown sugar at the end, not the beginning.
Stir the sauce well before you pour it over the chicken so the sugar and honey mix evenly.
Mix the cornstarch slurry with cold water only; hot water makes it clump.
Add the slurry near the end of cooking so the sauce thickens without turning gummy.
Taste the sauce before serving and tweak with a splash of vinegar, pinch of salt, or drizzle of honey as needed.

How to Make Slow cooker Orange Chicken Recipe

Step 1: Prep the chicken

Place the chicken pieces on a cutting board and trim any large bits of fat. Pat the chicken dry with paper towels so the cornstarch sticks. Toss the chicken in a large bowl with salt, pepper, and 2 tablespoons cornstarch until every piece looks lightly coated.

Step 2: Mix the orange sauce

In a medium bowl, whisk together orange juice, orange zest, soy sauce, honey, ketchup, rice vinegar, brown sugar, ginger, garlic, red pepper flakes, and sesame oil. Whisk until the honey and sugar dissolve and the mixture looks smooth. Taste a small spoonful and adjust with a pinch more sugar or vinegar if you want.

Step 3: Load the slow cooker

Lightly spray the inside of the slow cooker with cooking spray or rub with a bit of oil. Add the coated chicken pieces in an even layer. Pour the orange sauce over the chicken and stir gently so every piece sits in the sauce.

Step 4: Cook low and slow

Cover the slow cooker and cook on low for 3 to 4 hours. Stir once halfway through to keep the chicken coated and to check tenderness. Stop cooking when the chicken feels tender and cooked through but not shredded or dry.

Step 5: Thicken the sauce

In a small bowl, whisk 2 tablespoons cornstarch with 3 tablespoons cold water until smooth. Stir the slurry into the slow cooker along with the orange marmalade if you use it. Cover and cook on high for 15 to 20 minutes while the sauce bubbles and thickens to a glossy, spoon-coating consistency.

Step 6: Final taste and garnish

Lift the lid and give everything a gentle stir so the thickened sauce coats the chicken evenly. Taste and adjust seasoning with a pinch of salt, extra red pepper flakes, or a drizzle of honey if you want more heat or sweetness. Top with sliced green onions, toasted sesame seeds, and a little extra orange zest right before serving.

Recipe Variations

Gluten free: Use tamari or coconut aminos instead of soy sauce and confirm that your ketchup and vinegar list gluten free on the label.
Lower sugar: Cut the honey and brown sugar in half and skip the marmalade, then sweeten to taste at the end if needed.
Extra veggie: Add bell pepper strips, broccoli florets, or snap peas during the last 45 to 60 minutes so they stay crisp tender.
Spicy version: Increase red pepper flakes or stir in a spoonful of your favorite chili garlic sauce near the end.
Vegan: Swap chicken with extra firm tofu cubes or cauliflower florets, use vegetable broth to thin the sauce if needed, and cook on low for 2 to 3 hours until tender.
Low carb: Use a low sugar ketchup, reduce honey, skip brown sugar, and serve over cauliflower rice or steamed veggies.

Ways to Serve Slow cooker Orange Chicken Recipe

Spoon over hot jasmine rice, brown rice, or cauliflower rice.
Serve with steamed broccoli, green beans, or stir fried mixed vegetables on the side.
Pile into lettuce cups and top with shredded carrots and green onions for a lighter option.
Stuff into whole grain tortillas or flatbreads with crunchy slaw for a fun wrap.
Serve with plain noodles or lo mein style noodles and extra sauce.

Storage Success

Let the slow cooker orange chicken cool until it reaches room temperature, then transfer it to airtight containers. Store in the fridge for up to 4 days, and reheat gently on the stove over medium low heat with a splash of water or orange juice to loosen the sauce. Freeze portions in freezer safe containers for up to 3 months, then thaw overnight in the fridge before reheating. Stir during reheating so the sauce turns smooth again and coats the chicken nicely.
