There’s nothing quite like a vibrant, colorful stir-fry loaded with crisp-tender broccoli and cauliflower florets tossed in a silky, umami-rich sauce. This broccoli and cauliflower stir-fry recipe is one of my absolute favorite weeknight dinners because it’s not only delicious and satisfying, but it comes together in just about 20 minutes from start to finish!
I absolutely love making stir-fries at home because they’re so incredibly versatile. You can easily swap out vegetables based on what you have on hand, adjust the heat level to your preference, and serve it over rice, noodles, or even cauliflower rice for a lighter option. Plus, this recipe is naturally gluten-free if you use tamari instead of regular soy sauce, making it a fantastic choice for nearly any dietary preference.
What makes this stir-fry truly special is the perfect balance of flavors and textures. The broccoli and cauliflower become beautifully caramelized on the edges while maintaining that perfect tender-crisp bite, and they’re coated in the most incredible savory sauce that has just a hint of sweetness and a whisper of heat. I love to add some garlic, ginger, and a touch of sesame oil for that restaurant-quality depth of flavor that makes everyone ask for seconds.
This recipe is also wonderfully customizable! If you’re looking for a heartier meal, you can easily add protein like chicken, shrimp, or tofu. You could also try serving this alongside my Best Heavy Cream Alfredo Sauce Recipe if you want to create a surf-and-turf style dinner, or pair it with Easy Chicken Alfredo Recipe for a more indulgent meal.
I’ve been making stir-fries for years, and I’ve learned quite a few tricks along the way that really make a difference in the final result. The most important thing is to prep all your ingredients before you start cooking – stir-fries cook so quickly that there’s no time to chop vegetables once the pan is hot. I also recommend using a wok or large skillet for even heat distribution, and don’t overcrowd the pan, which can cause the vegetables to steam rather than sear beautifully.
For a complete meal, I often serve this alongside jasmine rice or brown rice, but you could also enjoy it with quinoa, farro, or even over a bed of fresh greens.

What I absolutely adore about this recipe is how it proves that healthy eating doesn’t have to be boring. The combination of fresh vegetables, bold flavors, and a beautiful glossy sauce makes this feel like you’re ordering takeout from your favorite restaurant, but it’s made right in your own kitchen. Plus, it’s a fantastic way to get more vegetables into your diet – and your family’s diet – without anyone even noticing!
According to Serious Eats’ guide to perfect stir-fries, the key to success is having your mise en place ready and maintaining high heat throughout the cooking process. I also love checking out Bon Appétit’s broccoli stir-fry recipes for inspiration on new flavor combinations.
This recipe serves four people as a main course when served over rice, or six people as a side dish. It’s also incredibly budget-friendly, especially if you buy your vegetables when they’re in season or on sale. The best part? You can make a double batch and have leftovers for lunch the next day – just store them in an airtight container in the refrigerator for up to three days. You can enjoy it cold, or simply reheat it gently in the microwave or stovetop.

Let me show you exactly how to make it!
Ingredients
- 3 cups fresh broccoli florets (about 1 medium head)
- 3 cups fresh cauliflower florets (about 1 small head)
- 3 tablespoons vegetable oil or peanut oil, divided
- 4 cloves garlic, minced
- 1 tablespoon fresh ginger, minced
- 3 tablespoons soy sauce or tamari
- 2 tablespoons rice vinegar
- 1 tablespoon honey or brown sugar
- 1 tablespoon sesame oil
- 1 teaspoon cornstarch
- ½ teaspoon red pepper flakes (optional, for heat)
- ¼ cup low-sodium vegetable broth or water
- 2 green onions, sliced thin
- 1 tablespoon sesame seeds (optional garnish)
- Salt and black pepper to taste
Instructions
- Prepare all ingredients before you begin cooking. Cut broccoli and cauliflower into bite-sized florets, making sure they’re roughly the same size so they cook evenly. Mince your garlic and ginger, and slice the green onions. This mise en place is essential for stir-fry success since everything cooks quickly once you start.
- In a small bowl, whisk together the soy sauce, rice vinegar, honey, sesame oil, cornstarch, red pepper flakes if using, and vegetable broth. Stir until the cornstarch is fully dissolved and the mixture is smooth. Set this sauce aside – this is what will bring everything together at the end.
- Heat a large wok or skillet over medium-high heat until it’s very hot – you should feel the heat radiating from it when you hold your hand about 6 inches above the surface. This high heat is crucial for achieving that beautiful caramelization on the vegetables.
- Once the wok is hot, add 1½ tablespoons of oil and swirl to coat the surface evenly. Allow the oil to heat for about 30 seconds until it just begins to shimmer and move fluidly around the pan.
- Add the broccoli florets to the hot oil in a single layer, allowing them to sit undisturbed for 2-3 minutes. This creates a beautiful golden-brown sear on one side. Don’t stir too frequently – let them get some color!
- After the broccoli has seared, add the cauliflower florets and stir everything together. Continue cooking for another 3-4 minutes, stirring occasionally, until both vegetables are starting to turn golden brown around the edges but still have a slight firmness to them.
- Push the vegetables to the sides of the wok, creating a well in the center. Add the remaining 1½ tablespoons of oil to the center well and let it heat for about 15 seconds until shimmering.
- Add the minced garlic and ginger to the center well and cook for about 30 seconds to 1 minute, stirring constantly. You’ll know it’s ready when the mixture becomes incredibly fragrant – that’s when you know the aromatics are properly bloomed and ready to flavor the entire dish.
- Pour the prepared sauce into the wok over the garlic and ginger mixture, stirring constantly to combine everything. The sauce will immediately begin to thicken and coat the vegetables beautifully.
- Toss all the vegetables with the sauce, stirring constantly for about 1-2 minutes until everything is well coated and heated through. The sauce should be glossy and cling to the vegetables in the most appetizing way.
- Taste the stir-fry and adjust the seasonings as needed – add more soy sauce for saltiness, more rice vinegar for tang, or more red pepper flakes for heat. Season with salt and black pepper to your preference.
- Transfer the finished stir-fry to a serving platter or individual bowls. Garnish generously with sliced green onions and sesame seeds if desired. Serve immediately over steamed rice, cauliflower rice, or rice noodles while it’s still hot and the vegetables are at their peak texture.
- Enjoy your beautiful, restaurant-quality stir-fry! Store any leftovers in an airtight container in the refrigerator for up to three days, and reheat gently when ready to eat again.
Pro Tips
- **Pro Tip for Perfectly Crisp Vegetables**: The key to achieving that ideal tender-crisp texture is not to overcrowd your pan. If your wok or skillet isn’t large enough, cook the broccoli and cauliflower in two batches. Overcrowding causes the vegetables to release moisture and steam rather than sear, which prevents that beautiful golden-brown caramelization we’re after.
- **Sauce Consistency Control**: If your sauce ends up too thin, you can mix an additional ½ teaspoon of cornstarch with 1 tablespoon of water and stir it in at the end. If it’s too thick, simply add more broth or water a teaspoon at a time until you reach the desired consistency.
- **Make It a Protein-Packed Meal**: This stir-fry is perfect for adding protein! You can add diced chicken, shrimp, beef, or cubed tofu. Cook your protein first, set it aside, then follow the recipe as written, adding the cooked protein back in when you add the sauce.
- **Storage and Reheating**: Store leftovers in an airtight container in the refrigerator for up to three days. Reheat gently on the stovetop over medium heat, stirring occasionally and adding a splash of water if the sauce has thickened too much. You can also reheat in the microwave in 1-minute intervals, stirring between each minute.
- **Vegetable Substitutions**: Don’t have broccoli and cauliflower on hand? Try bell peppers, snap peas, bok choy, mushrooms, carrots, or green beans. The cooking time might vary slightly depending on which vegetables you choose, so adjust accordingly.
- **Oil Selection Matters**: Use an oil with a high smoke point like vegetable oil, peanut oil, or avocado oil. Avoid olive oil for stir-frying as it has a lower smoke point and can burn at the high temperatures required.
- **Freshness Indicators**: Choose broccoli and cauliflower that are bright in color with no yellowing or dark spots. The florets should feel firm when gently squeezed, not soft or mushy. Fresh produce will give you the best results.
- **Make Ahead Preparation**: You can prep your ingredients several hours in advance. Keep the cut vegetables in separate containers in the refrigerator, and prepare your sauce in a small bowl. This makes weeknight cooking even faster!
- **Sodium Considerations**: If you’re watching your sodium intake, use low-sodium soy sauce and reduce the amount to 2 tablespoons, tasting and adjusting as needed. You can add depth with additional sesame oil or a splash of mirin instead.
- **Serving Suggestions**: Serve over jasmine rice, brown rice, quinoa, rice noodles, or even cauliflower rice for a lower-carb option.
