This zucchini mushroom chicken stir fry has become my weeknight dinner hero whenever I need something quick, nutritious, and delicious. The combination of tender chicken, earthy mushrooms, and fresh zucchini creates a perfect balance of flavors and textures that never disappoints.
I first created this recipe when I needed to use up some garden zucchini that was threatening to take over my refrigerator. My family was so impressed with how flavorful it was that it quickly became part of our regular rotation, especially on busy weeknights.
Ingredients
- Boneless skinless chicken breasts: provide lean protein and cook quickly when cut into bite sized pieces
- Zucchini: adds freshness, nutrition and a tender crisp texture that soaks up the sauce beautifully
- Mushrooms: contribute meaty texture and umami flavor that makes this dish especially satisfying
- Garlic and ginger: form the aromatic base that gives authentic Asian flavor to the stir fry
- Soy sauce: delivers that essential salty flavor that brings everything together
- Oyster sauce: adds complex umami notes that make this taste like restaurant quality
- Sesame oil: provides that distinctive nutty finish that elevates the entire dish
- Cornstarch: creates the perfect silky sauce that clings to every bite
Step-by-Step Instructions
- Prepare the Protein:
- Cut chicken into uniform bite sized pieces to ensure even cooking. Season lightly with salt and pepper before cooking to build flavor from the beginning. Sear the chicken in hot oil until just cooked through about 5 to 6 minutes. The goal is to get some browning without overcooking the chicken.
- Create the Flavor Base:
- Add fresh minced garlic and ginger to the hot pan. This brief cooking period of about 30 seconds releases their essential oils and creates an aromatic foundation for the dish. The fragrance that fills your kitchen at this point is absolutely intoxicating.
- Cook the Vegetables:
- Add mushrooms and zucchini to the hot pan and stir fry until they release their moisture and begin to tenderize. The key is maintaining high heat to quickly cook the vegetables while preserving their texture. You want them tender but not mushy, which takes about 4 to 5 minutes.
- Combine and Sauce:
- Return the chicken to the pan and pour in the sauce ingredients. Toss everything together so each piece gets coated in the flavorful sauce. The soy sauce and oyster sauce will immediately begin to caramelize slightly on the hot ingredients, creating deeper flavor.
- Thicken the Sauce:
- Pour in the cornstarch slurry and stir immediately. The sauce will transform before your eyes, becoming glossy and thickening just enough to cling to the chicken and vegetables. This takes just 1 to 2 minutes of cooking while stirring.
- Finish with Freshness:
- Add green onions at the very end to maintain their color and fresh flavor. Taste and adjust seasonings as needed. The final dish should have a perfect balance of savory, umami, and slightly sweet notes.

The fresh ginger makes all the difference in this recipe. I once tried making it with powdered ginger in a pinch, and while still good, it lacked that bright zingy quality that fresh ginger brings. Now I keep ginger root in my freezer and grate it directly into dishes when needed.
Make Ahead and Storage
This stir fry reheats beautifully, making it perfect for meal prep. Store leftovers in an airtight container in the refrigerator for up to 3 days. The flavors actually develop and deepen overnight, sometimes making the leftovers even more delicious than the fresh version. Reheat gently in a skillet with a splash of water to refresh the sauce, or microwave until just heated through.
Easy Substitutions
This recipe welcomes adaptations based on what you have available. Bell peppers, snap peas, or broccoli can replace or supplement the zucchini. Beef or shrimp work wonderfully instead of chicken. For a vegetarian version, try using firm tofu or simply double the mushrooms for a hearty meatless meal. If you dont have oyster sauce, you can substitute with additional soy sauce and a pinch of sugar to mimic that sweet umami quality.
Serving Suggestions
While delicious on its own, this stir fry pairs perfectly with steamed rice, which soaks up the savory sauce beautifully. For a lower carb option, serve it over cauliflower rice or alongside a simple cucumber salad dressed with rice vinegar. To make it a heartier meal, consider adding some cooked noodles like ramen or udon directly to the pan during the final minute of cooking.
Flavor Boosters
Experiment with adding a tablespoon of chili garlic sauce or sriracha for heat lovers. A squeeze of fresh lime juice just before serving brightens all the flavors. Add a handful of fresh herbs like basil, cilantro, or mint at the end for a fresh dimension.
Recipe FAQs
- → Can I use different vegetables in this stir-fry?
Absolutely! This stir-fry is very versatile. Try bell peppers, snap peas, broccoli, or carrots. Just adjust cooking times as needed - harder vegetables should go in earlier, while quick-cooking ones can be added later.
- → Is there a substitute for oyster sauce?
Yes, you can substitute oyster sauce with hoisin sauce for a similar sweet-savory flavor, or use an extra tablespoon of soy sauce mixed with a teaspoon of sugar. For vegetarian versions, look for mushroom-based oyster sauce alternatives.
- → How do I prevent the chicken from becoming tough?
The key is not to overcook it. Cut the chicken into evenly-sized pieces, cook it quickly over medium-high heat just until no longer pink (5-6 minutes), and remove it from the pan while cooking the vegetables. Adding it back later prevents it from becoming dry and tough.
- → What can I serve with this stir-fry?
Steamed white or brown rice makes a perfect base for this dish. Other excellent options include noodles (like lo mein or rice noodles), cauliflower rice for a low-carb option, or even wrapped in lettuce cups for a light meal.
- → How can I make this dish spicy?
To add heat, incorporate sliced fresh chilis or red pepper flakes when sautéing the garlic and ginger. Alternatively, add a teaspoon of chili garlic sauce or sriracha to the sauce mixture. Adjust the amount based on your preferred spice level.
- → Can I prepare any components ahead of time?
Yes! Slice all vegetables and chicken up to a day in advance and store in separate containers in the refrigerator. You can also mix the sauce ingredients ahead of time. This makes the actual cooking process much faster when you're ready to prepare the meal.
