Seven ingredients, one skillet, and dinner is on the table in 30 minutes. This peanut chicken uses creamy peanut butter, soy sauce, and garlic salt to make a savory glaze that coats tender chicken breast, then gets served over spaghetti with fresh scallions on top. It’s the kind of weeknight dinner that looks more involved than it is — which is exactly the point.
What makes this version work
Two things matter here. First, cutting the chicken into uniform 1-inch pieces means every piece finishes cooking at the same time — no dry edges waiting on an undercooked center. Second, the peanut butter goes into a hot, empty skillet after the chicken comes out, not into a cold pan and not on top of the chicken. That brief 1-2 minutes of direct heat loosens the peanut butter, picks up the browned bits left by the chicken, and turns what would otherwise be a clumpy paste into a smooth, clingy sauce. Those two steps are the whole recipe.
Ingredient notes
- Peanut butter: Use a standard creamy peanut butter like Jif or Skippy — the kind with a little added sugar and oil. Natural peanut butter (the separated kind) can seize up in the hot pan and turn grainy instead of smooth.
- Garlic salt: This is doing double duty — seasoning and garlic flavor in one. If you only have garlic powder and kosher salt, use ¼ teaspoon garlic powder plus ¼ teaspoon salt as a straight swap.
- Scallions: The white and light green parts go into the sauce; the dark green tops are reserved for garnish. Skip the garnish — not worth the extra dish if you’re feeding kids who’ll push it aside anyway.
What can go wrong
- The sauce turns into a thick, sticky paste: Peanut butter tightens fast over heat. Have a small cup of water next to the stove before you start. Add it one tablespoon at a time and stir — it loosens immediately.
- The chicken releases a lot of liquid and won’t brown: This happens when the pieces are crowded or the pan isn’t hot enough before you add the chicken. Let the oil shimmer before adding anything, and leave space between pieces. Crowded chicken steams; spaced chicken sears.
- The soy sauce makes the finished dish too salty: Soy sauce varies a lot by brand. If you’re using a full-sodium variety like Kikkoman, taste the chicken after tossing it in the marinade — if it already tastes sharp, reduce to 1½ tablespoons.
- The pasta finishes before the chicken: Start the pasta water when you start cutting the chicken. Most spaghetti takes 9-11 minutes; the chicken takes about 8 minutes total. They should land close together, but if the pasta is done first, toss it with a tiny splash of the pasta water to keep it from sticking while you finish the sauce.
Storage and reheating
Store leftovers in an airtight container in the fridge for up to 3 days. Keep the chicken and pasta together — they reheat fine as one unit. To reheat, add a splash of water (about 1 tablespoon) to a skillet over medium-low heat, add the leftovers, and stir until warmed through, about 3-4 minutes. The water revives the sauce. Microwaving works too — cover loosely and heat in 60-second intervals, stirring between each. This dish doesn’t freeze well; the peanut butter sauce separates when thawed and the pasta turns mushy.
Peanut Chicken with Spaghetti (Ready in 30 Min)
Ingredients
- 1 lb chicken breast boneless, skinless, cut into 1-inch pieces
- 2 tablespoons soy sauce
- ½ teaspoon garlic salt adjust to taste
- 1 tablespoon vegetable oil
- 2 tablespoons creamy peanut butter
- 3 whole scallions thinly sliced, green and white parts separated
- 8 oz spaghetti
- as needed water for thinning sauce / boiling pasta
- 1 pinch salt to taste; for pasta water
Instructions
- Mix the chicken, soy sauce, and garlic salt in a medium bowl. Cut the chicken breast into 1-inch (2.5cm) pieces. Combine the chicken pieces, soy sauce, and garlic salt in a medium bowl. Toss to coat evenly and set aside while you prepare the remaining ingredients.
- Heat the oil in a large skillet over medium-high heat. Heat the vegetable oil in a large skillet over medium-high heat until shimmering. Add the chicken mixture and cook through. Add the chicken in a single layer (work in batches if needed to avoid crowding) and cook for 5-6 minutes, turning occasionally, until golden on the outside and cooked through (internal temperature of 165°F / 74°C). Remove the chicken from the skillet. Transfer the chicken to a clean plate.
- Add the peanut butter and 2/3 of the chopped scallions to the skillet and cook together for 1 to 2 minutes. Reduce heat to medium. Add the peanut butter and the white and light green parts of the scallions to the skillet. Stir constantly for 1 to 2 minutes until the peanut butter melts and forms a smooth sauce. If the sauce is too thick, add 1-2 tablespoons of water to thin it. Add the chicken back to the skillet and heat through. Return the chicken to the skillet and toss to coat evenly. Cook for 1 minute until heated through.
- Serve chicken on top of spaghetti and garnish with additional scallions. Meanwhile, cook the spaghetti in a large pot of salted boiling water according to package directions until al dente. Drain well. Divide the spaghetti between 2 plates or bowls, top with the peanut chicken and sauce, and garnish with the reserved scallion greens. Serve immediately.

FAQ
Can I use chicken thighs instead of chicken breast?
Yes, boneless skinless chicken thighs work well here. They stay a little juicier than breast meat and are more forgiving if you cook them slightly longer — just cut them into the same 1-inch pieces so they cook evenly.
Can I use a different pasta instead of spaghetti?
Any long or medium pasta works fine — linguine, fettuccine, or even rotini. Avoid very thin pasta like angel hair, which tends to clump under a thick sauce like this one.
How do I know when the chicken is actually cooked through without a thermometer?
Cut into the thickest piece — the inside should be completely white with no pink, and the juices should run clear. If you see any translucent or pink flesh, give it another minute and check again.
Is this dish spicy?
No, there’s nothing spicy in this recipe as written. The flavor is savory, mildly nutty, and slightly salty — most kids take to it easily.
