This Chicken and Broccoli Stir-Fry is a fast weeknight dinner that beats takeout. Thin strips of chicken and crisp-tender broccoli get tossed in a garlicky soy sauce that turns glossy and just a little sticky.

It’s made for two, uses a short list of pantry ingredients, and takes about 25 minutes. You don’t need a wok. A large skillet works just fine.

Why This Stir-Fry Works

The chicken cooks first, then comes out of the pan. That keeps it from overcooking while the broccoli gets its turn. When everything goes back together with the sauce, the chicken is still juicy.

The sauce is simple. Soy sauce brings salt, oyster sauce adds a rich, slightly sweet depth, and a small cornstarch slurry thickens it so it clings to every piece. One clove of garlic is enough to flavor the whole pan.

Ingredients and Easy Swaps

• Chicken breasts: 2 boneless breasts, sliced thin. Boneless thighs stay juicier and are hard to overcook.
• Broccoli florets: 2 cups. Snap peas, sliced bell peppers, or green beans can replace some or all of it.
• Vegetable oil: 1 tablespoon. Any high-heat oil works, like canola or avocado.
• Garlic: 1 clove, minced. Add a teaspoon of grated ginger for extra flavor.
• Soy sauce: 2 tablespoons. Use low-sodium soy sauce or tamari for gluten-free.
• Oyster sauce: 1 tablespoon, optional. Hoisin is a sweeter swap.
• Cornstarch: 1 teaspoon mixed with 2 tablespoons water.
• Salt and pepper: To taste. Go easy on salt since soy sauce is already salty.

How to Make It at a Glance

1. Heat the oil in a large skillet over medium-high heat.
2. Cook the chicken until browned and 165°F inside, then move it to a plate.
3. Stir-fry the broccoli and garlic for 3 to 4 minutes.
4. Return the chicken, add the soy sauce, oyster sauce, and cornstarch slurry, and stir until thick and glossy.

Equipment You’ll Need

• Large skillet or wok
• Sharp knife and cutting board
• Small bowl for the cornstarch slurry

Common Mistakes to Avoid

Crowding the pan. Too much chicken at once steams instead of browning. Cook it in two batches if your skillet is small.

Cutting uneven slices. Slice the chicken about ¼ inch thick so it cooks evenly. A partly frozen breast is easier to slice thin.

Overcooking the broccoli. It should be bright green with a little bite. If it’s still too firm, add a tablespoon of water and cover for 1 minute.

Adding dry cornstarch. Always mix it with water first. Stir it again right before adding, since it settles fast.

Variations

• Spicy: Add red pepper flakes or a spoonful of chili garlic sauce.
• Beef and broccoli: Use thinly sliced flank steak instead of chicken.
• Sesame: Finish with a few drops of toasted sesame oil and a sprinkle of sesame seeds.
• Cashew chicken: Toss in a handful of roasted cashews at the end.

What to Serve With It

Steamed jasmine rice is the classic choice. Rice noodles, lo mein noodles, or brown rice also work. For a low-carb plate, serve it over cauliflower rice. Add egg rolls or a quick cucumber salad on the side if you want more.

Make Ahead, Storage, and Reheating

Make ahead: Slice the chicken, cut the broccoli, and mix the sauce up to a day ahead. Keep them in separate containers in the fridge.

Storage: Store leftovers in a sealed container in the fridge for up to 2 days.

Reheating: Warm in a skillet over medium heat with a splash of water, or microwave until the chicken is hot all the way through.

FAQ

Can I use frozen broccoli?
Yes. Thaw it and pat it dry first so it doesn’t water down the sauce.

Can I double it?
Yes. Double everything and cook the chicken in batches so it browns well.

What if I don’t have oyster sauce?
Skip it or use 1 tablespoon of hoisin. The dish still tastes great with soy sauce alone.

Is this stir-fry gluten-free?
It can be. Use tamari or a gluten-free soy sauce, and check that your oyster sauce is labeled gluten-free.

How do I keep the chicken tender?
Toss the sliced chicken with ½ teaspoon of cornstarch and a splash of soy sauce before cooking. This light coating helps it stay soft and juicy.

Tips for the Best Results

• Get everything chopped and the sauce mixed before you turn on the heat. Stir-fries cook fast.
• Let the pan get hot before the chicken goes in. You should hear a strong sizzle.
• Cut the broccoli into small, even florets so they cook in 3 to 4 minutes.
• Add the garlic with the broccoli, not before. Garlic burns quickly in a very hot pan.

Leftover Ideas

Turn leftovers into fried rice. Heat a little oil, add cold cooked rice, then stir in the chopped chicken and broccoli and a scrambled egg. A splash of soy sauce brings it together. Leftovers also make a quick lunch wrapped in a warm tortilla with a little sriracha mayo.

Budget Tips

Boneless thighs often cost less than breasts and taste great in a stir-fry. Buy whole heads of broccoli instead of pre-cut florets and slice the peeled stems into coins to use them too. Soy sauce and oyster sauce last a long time in the fridge, so one bottle covers many dinners.
