Let’s get the most important thing out on the table here: Anything that is meatless and still pleases my husband is a WINNER WINNER chicken dinner. Minus the chicken part…for obvious reasons…okay just a winner dinner.

So what is this exactly? It’s cauliflower florets, tossed in a bit of oil and coated in cornstarch and then baked to perfection. Crispy on the outside, tender on the inside. A lot like chicken, only more cauliflower-y. And all of that faux-fried cauliflower goodness is then tossed in the best sweet and sour sauce. You will want to put this sauce on e-ver-y-thing. It’s incredibly easy to make and the flavor is spot-on.

Eating meatless once in a while is healthier for you, is a great way to incorporate more plant proteins into your diet, is more nutritional (and cheaper) than takeout, and it is better for the planet, a big consideration on a lot of people’s minds these days. If you’re looking for more meatless options, then this Asian cauliflower dish is the perfect place to start. 

This dish is a great entry into the world of meatless meals if you are simply trying to be okay with the idea of eating cauliflower where chicken and pork usually take the stage. Whatever the reason, I’m positive this baked sweet & sour cauliflower thing will fit in there somewhere.


I like to serve this dish over rice. Sweet & Sour over starchy & simple is kinda how we roll at this house. But there are other just as delicious ways to serve up this cauliflower recipe. 

  • Sure, you could use regular white rice, but what about brown rice or even cauliflower rice? (That one isn’t for those with sensitive stomachs, though!)
  • Serve them alone, as an appetizer. Think of them like meatless wings with an Asian sauce.
  • Serve this cauliflower over zucchini or yellow squash noodles. You could even try half a cooked spaghetti squash for a purely vegetarian dish. 
  • Make kebabs by alternating cauliflower with pineapple before or after baking. 
  • Add sweet & sour cauliflower over quinoa, barley, or wild rice for a truly nutty tasting, filling meal.

Although it might sound complicated, it’s not at all. If you can cut and bake chicken or pork with sauce, then you can do the same to a veggie! 

Preheat the oven to 425 degrees, and grease a baking sheet. Combine the cut cauliflower and oil in a large air-tight bag. Make sure it’s sealed and give it a good shake to coat all the cauliflower thoroughly. Open the bag back up and add cornstarch. Seal the bag back up and shake some more to make sure the cornstarch now coats the cauliflower pieces. 

Now that the cauliflower is coated in both oil and cornstarch, you can transfer it to the greased pan. Spread it out into one even layer and bake for 15-20 minutes or until it starts to brown on the bottoms. Change the oven over to broil and cook on high another 3-4 minutes under the broiler to get the tops to brown as well. Make sure to keep a close eye on it so it doesn’t burn. 

While the cauliflower is cooking, you can make the sauce. Mix together sugar, vinegar, soy sauce, garlic powder, onion salt and ketchup in a medium saucepan at high heat and let it come to a boil while you stir. 

In another small bowl, whisk together 1 tablespoon of cornstarch into cold water until it dissolves. Add this mixture to the sauce pan and stir it all together until it thickens some more, then turn the burner down to low heat. 

When the cauliflower is done baking, toss it and the sauce together in a heat-safe bowl. Serve! 


I cut cauliflower similarly to how I cut broccoli. That is to say, break it down from bigger to smaller pieces. 

  1. First, remove the leaves. 
  2. Turn the head upside down and cut out the stem. 
  3. Either break or cut the bigger pieces of florets off. 
  4. Cut the larger parts of the stems off the bigger florets, if desired. 
  5. Take each larger floret and cut those down into smaller ones, or the desired size for the recipe. 

For this recipe, I like to keep the florets around 2 inches long so they bake more evenly and crisp up just the right amount.  


Believe it or not, cauliflower is considered a superfood. Right up there with kale and acai berries, and pomegranate juice, I suppose. It’s chock full of vitamins B and C as well as fiber and antioxidants and it’s low in calories and has zero fat. 

So go ahead, see what all the cauliflower buzz is about!

“I’m very pleasantly surprised by this sauce! I was pretty suspicious of it (“ketchup, really? Where are the pineapples, the peppers?”), but it turned out great, almost just like the red sweet-and-sour sauce at my favorite Chinese restaurants. I’ll definitely be using that recipe again.” – Steph

Terrific result. I doubled the veggies, adding tofu, zucchini and broccolini. Then I halved the sauce. It came out perfectly. If I hadn’t read the other reviews, and adjusted accordingly, it would have been crazy sweet.

    Thanks for your feedback, Jodie!

Can I sub monkfruit for the sugar? My husband is diabetic.

    Hi Kathleen! I don’t have any experience using monk fruit, sorry. I wish I had better advice for you on that one!
