I love weeknight stir-fries because they’re fast, forgiving, and endlessly adaptable. This Chop Suey Stir Fry is one of those dishes — bright vegetables, tender chicken, and a glossy, savory sauce. It comes together in under an hour, most of which is passive marinating time, and it feeds a small family or makes great leftovers.

There’s nothing fancy here: straightforward pantry staples, a little technique for texture, and steps you can follow without standing over the stove. I’ll walk you through what to buy, how to prep and cook, and the simple swaps that keep the flavor interesting. Ready? Let’s make a reliable, homey Chop Suey Stir Fry tonight.

Your Shopping Guide

½ pound chicken breast (boneless and skinless, thinly sliced) — the lean protein; slice thin for quick, tender cooking.
1 egg white — used to give the chicken a velvety coating and help the cornstarch adhere.
1 tablespoon cornstarch — for the chicken marinade; helps create a silky texture.
1 tablespoon soy sauce — added to the chicken marinade for seasoning and umami.
2 tablespoons vegetable oil — neutral oil for high-heat stir-frying.
2 cloves garlic (minced) — aromatic base; add early so it flavors the oil.
1 medium onion (thinly sliced) — provides sweetness and body; slice thin so it softens quickly.
1 medium bell pepper (sliced in strips) — color and crunch; slice into even strips for uniform cooking.
2 cups mixed vegetables (like carrots, snow peas, broccoli or baby corn, bite sized) — the veg medley is the heart of chop suey; choose a mix for texture contrast.
¼ cup soy sauce (low sodium) — main savory seasoning for the sauce; low sodium lets you control salt.
2 tablespoons oyster sauce — deepens and sweetens the sauce; gives that restaurant-style gloss.
1 teaspoon sugar — balances salt and adds a touch of brightness.
Salt and pepper (to taste) — final seasoning; adjust after tasting the sauce.
1 cup chicken broth (low sodium or no sodium added) — builds the pan sauce; choose low/no sodium to avoid over-salting.
2 tablespoons cornstarch (mixed with 4 tablespoons of water) — slurry to thicken the sauce to a clingy, glossy finish.

Step-by-Step: Chop Suey Stir Fry

Prep (start here)

Whisk 1 egg white, 1 tablespoon cornstarch, and 1 tablespoon soy sauce in a medium bowl until smooth.
Add the ½ pound thinly sliced chicken breast to the bowl and toss so each piece is coated. Cover and refrigerate for 30 minutes to marinate.
While the chicken marinates, mince the garlic, thinly slice the onion, slice the bell pepper into strips, and prep 2 cups mixed vegetables into bite-sized pieces.
Mix 2 tablespoons cornstarch with 4 tablespoons water in a small bowl and set aside as your slurry.

Cook

Heat 1 tablespoon vegetable oil in a skillet or wok over medium heat. Add the marinated chicken in a single layer and cook 2–3 minutes, just until the chicken turns opaque. It will not be fully browned — you’re partially cooking it. Remove the chicken and set aside.
Increase heat to medium-high and add the remaining 1 tablespoon vegetable oil to the same skillet or wok. Add the minced garlic and thinly sliced onion and stir-fry about 2 minutes, until the onion is translucent and fragrant.
Add the bell pepper and the 2 cups mixed vegetables. Stir-fry 3–4 minutes, tossing frequently so vegetables stay crisp-tender.
Return the cooked chicken to the skillet and stir to combine with the vegetables.
Pour in ¼ cup soy sauce and 2 tablespoons oyster sauce. Add 1 teaspoon sugar and season with salt and pepper to taste. Stir everything to incorporate the sauces evenly.
Pour in 1 cup chicken broth and bring the mixture to a gentle simmer so the flavors mingle.
Gradually stir in the cornstarch-water slurry while stirring continuously. Cook about 2 minutes, until the sauce thickens and becomes glossy, coating the chicken and vegetables.
Remove from heat. Taste and adjust seasoning if necessary. Serve immediately with cooked rice.

Why Cooks Rave About It

This Chop Suey Stir Fry hits the trifecta: speed, texture, and balance. The quick marinade keeps the chicken tender; the high-heat stir-fry keeps vegetables vibrant and slightly crisp; the sauce is savory with a touch of sweetness and a glossy finish that makes every bite satisfying. It’s flexible enough to use whatever produce you have and forgiving in timing — a tiny extra minute on the veggies won’t ruin the dish.

Flavor-Forward Alternatives

Swap protein — use thinly sliced pork loin, firm tofu, or shrimp. Adjust cook time: tofu needs gentle browning, shrimp cooks in 2–3 minutes.
Go spicy — add 1 teaspoon chili paste or sliced fresh chilies with the garlic for heat.
Use different sauces — replace oyster sauce with hoisin for a sweeter profile, or add a splash of rice vinegar for brightness.
Make it gluten-free — use tamari instead of soy sauce and check oyster sauce label or use a gluten-free alternative.

Tools of the Trade

Wok or large skillet — wide surface for even high-heat cooking and tossing.
Sharp knife and cutting board — uniform slices mean even cooking.
Small whisk or fork — for combining marinades and slurry smoothly.
Heatproof spatula or wooden spoon — to stir and scrape without damaging the pan.

Frequent Missteps to Avoid

Overcrowding the pan — crowding cools the pan and steams the meat and veg. Cook in batches if necessary.
Skipping the marinade — the egg white and cornstarch coating improves chicken texture and mouthfeel; don’t skip it.
Cooking vegetables too long — stir-fry means quick, high heat. Aim for crisp-tender, not mushy.
Adding the slurry too fast — pour the cornstarch slurry slowly while stirring to prevent lumps and reach the right sauce thickness.

Fresh Seasonal Changes

Spring — use asparagus tips and sugar snap peas for a bright, green stir-fry.
Summer — add summer squash and use colorful bell peppers at peak ripeness.
Fall — include sliced baby bok choy and thinly sliced carrots; they hold up well to stir-frying.
Winter — frozen mixed vegetables work fine; add broccoli florets and baby corn for heartiness.

Cook’s Notes

Marinade time — 30 minutes in the fridge is ideal. If you’re in a rush, 15 minutes still helps. Don’t exceed 2 hours; the egg white benefits are front-loaded.
Chicken slices — slice against the grain and as thin as possible for tender bites and fast cooking.
Sauce balance — using low-sodium soy sauce and low/no-sodium broth gives you control; always taste before adding salt.
Leftovers — the sauce thickens as it cools; add a splash of water or broth when reheating to loosen it up.

Storage & Reheat Guide

Refrigerator — store in an airtight container for up to 3 days.
Freezer — not recommended for best texture, but you can freeze for up to 1 month; thaw overnight in the fridge before reheating.
Reheating — reheat gently in a skillet over medium heat with a tablespoon or two of water or broth to refresh the sauce; microwave on medium power in short bursts, stirring between intervals.

Troubleshooting Q&A

Q: My sauce is lumpy after adding the slurry. What went wrong? — A: You likely added the slurry too quickly or didn’t stir continuously. Whisk the slurry before adding and pour slowly while stirring. If lumps form, strain the sauce quickly or keep stirring over low heat to dissolve.
Q: The chicken is chewy. How can I prevent that? — A: Slice the chicken thinly against the grain and don’t overcook. The quick sear in step one is just to set the exterior; finishing in the sauce will cook it through without drying.
Q: Vegetables turned soggy. — A: Your heat was too low or you cooked too long. Use higher heat and toss often; add heartier vegetables first and softer ones later.
Q: Too salty? — A: Add a splash of water or more low-sodium broth and a small pinch of sugar to balance, or serve with extra rice to dilute intensity.
