What is kung pao?

Kung pao is a Chinese dish made with chicken, peanuts, vegetables and chili peppers. It has an intense sweet and sour flavour with some heat from sichuan peppers.

This recipe is inspired by Westernized kung pao and is definitely not authentic in any way.

Ingredient Notes

Visual list of ingredients for kung pao cauliflower. Each ingredient is labelled with text overlay.
  • cauliflower – you’ll need two small to medium sized heads
  • bell peppers – the recipe calls for red bell peppers but you could use another color in a pinch
  • sesame oil – key for flavor, don’t skip it!
  • serrano chili – can be substituted with sichuan pepper or if you can’t find either, jalapeno will work
  • low-sodium soy sauce – it’s important ot use a low-sodium variety otherwise the sauce will be too salty, for a gluten-free recipe, use low-sodium tamari
  • maple syrup – agave syrup or honey (not vegan) also work here
  • rice wine vinegar – seasoned or unseasoned both work, I used unseasoned

This list is not complete. Please see the recipe card at the end of the post for the complete ingredient list with measurements and detailed instructions.

Step-by-Step Instructions

Before you Start: To get prepped for the recipe, chop the cauliflower, peppers, garlic, ginger and Serrano pepper and get the all of the sauce ingredients ready to go.

Step 1. Preheat the oven to 450 F. Arrange the cauliflower and bell pepper in a single layer on a baking tray and roast for about 15 minutes until browned and tender.

Step 2. Make the Sauce

  1. Start by heating the sesame oil in a skillet then sautéing the ginger, Serrano pepper for 2-3 minutes.
  2. Mix the maple syrup, soy sauce and 2 vinegars together in a bowl and add to the pan.
  3. Bring to a light boil, then reduce heat and cook for a couple of minutes to slightly reduce.
  4. Mix the water and cornstarch together until smooth then pour into the an, reduce heat and stir to thicken, about 1-2 minutes.

Step 3. Finally add the roasted veggies to the pan with the sauce and toss to coat.

Can I use different vegetables? Sure! Try it with broccoli instead instead of cauliflower to switch things up! The sauce is also perfect for coating crispy tofu, tempeh, seitan, plant-based chicken or chickpeas.

Cauliflower Batter Variation

I kept this recipe very simple and did not batter the cauliflower, however, adding a batter really takes it up a notch and it only requires a simple extra step and 2 extra ingredients.

If you’d like to try it battered, use the recipe from my buffalo cauliflower wraps (just the batter part, not the buffalo sauce!). You’ll need:

  • 3/4 cup brown rice flour
  • 3/4 cup unsweetened almond milk (plus more as needed to adjust consistency)
  • pinch of salt and pepper

Everything else in the recipe stays the same.

Storing

  • Store on its own or with rice.
  • Let cool then store in the fridge in an airtight container for up to 4 days.
  • Reheat on the stovetop or in the microwave until heated to your preference.
  • This recipe is not ideal for freezing.

Ingredients 

For the Vegetables

  • 2 small to medium-sized heads cauliflower, cut into florets (1900 g)
  • 2 red peppers, thinly sliced (275 g)
  • 1 tbsp sesame oil, 15 ml
  • 5 cloves garlic, finely chopped (20 g)
  • 2 tbsp peeled and finely chopped fresh ginger, 20 g
  • 1 Serrano chilli, seeds removed and finely chopped (20 g)

For the Kung Pao Sauce

  • 2/3 cup low sodium soy sauce, 160 ml
  • 2 tbsp maple syrup, 30 ml
  • 3 tbsp rice wine vinegar, unseasoned (45 ml)
  • 3 tbsp balsamic vinegar, 45 ml
  • 2 tbsp corn starch, 15 g
  • 1/3 cup water, 80 ml

For Serving

  • 1 bunch green onion, sliced (50 g)
  • 1/2 cup roasted peanuts, 125 g
  • cooked rice

Instructions 

  • Preheat oven to 450 degrees F. 
  • Place cauliflower florets and sliced red pepper on a baking sheet and roast for 15 minutes, until slightly golden brown. 
  • In a medium bowl mix together the soy sauce, maple syrup and 2 vinegars and set aside for now.
  • While the cauliflower and peppers are roasting, take a large sauté pan and heat the sesame oil. Over medium heat sauté the garlic, ginger and serrano chilli. Cook until garlic is golden brown, roughly 2 minutes. Be aware the heat from the chilli can be quite powerful so be careful what you touch and make sure you wash your hands well after handling.
  • Pour the prepared sauce into the pan with sautéed garlic and ginger, bring to a boil, reduce heat and cook for a few minutes to slightly reduce.
  • In the same bowl you used for the soy sauce mixture, mix the water and corn starch together until smooth and pour into the sauté pan. Stir the sauce until thickened, roughly 1-2 minutes. 
  • Remove roasted cauliflower and red peppers from the oven and add to the pan. Toss in the sauce until fully coated. 
  • Serve immediately over a bed of cooked rice and top with roasted peanuts and sliced green onions.

    Absolutely delicious – a restaurant quality dinner with best of all, minimal effort! ย I agree with others that it takes realistically @ 25 minutes to roast the cauliflower and red peppers. ย Those extra few minute will not deter me from making this dish again. ย  I served it with baked tofu cubes and jasmine rice. ย This is definitely going into my dinner rotation. ย Thank you!

  2. I’m wondering how I might add tempeh to this dish. Put it in the oven with the veggies? Any thoughts? Thank you.

    1. That’s what I would do! You could also pan-fry or air fry it separately but really no need, I’d just roast with the veggies.

  3. 5 stars
    Tasted like something Iโ€™d order in a restaurant !! So impressed with how good it was. Took awhile to bake then stir fry the veggies but so worth it.ย 

  4. 5 stars
    Great recipe again thanks Deryn! I did not have any rice wine vinegar so used white wine vinegar instead and that seemed to work fine.

  5. 5 stars
    Deryn does it again! This recipe is so easy and sooooo delicious! Do yourself a favor and take the extra minute to use the batter recipe from her buffalo cauliflower wrap (which is excellent as well). Super quick coming together and the flavor is just what you want and expect from a Kung Pao recipe.ย 

    1. So great to hear, Angi! Glad the batter worked out well for you, great feedback! Thank you for the review.
