Ingredients
- Cauliflower florets: fresh is best for texture check for vibrant white heads free from brown spots
- Low sodium soy sauce: brings the umami while keeping it lighter than regular soy Choose a naturally brewed option for best taste
- Pure maple syrup honey or agave: for sticky sweetness Use real maple syrup for top shelf flavor
- Rice vinegar: adds the tang that balances the sweetness Select an unseasoned variety for the cleanest taste
- Minced garlic: fresh garlic gives deeper flavor than jarred or powdered
- Toasted sesame oil: this adds unbeatable nutty aroma Always choose toasted rather than regular sesame oil
- Powdered ginger: dried ginger gives warmth If you have fresh ginger you can grate it in for a brighter zing
- Cornstarch or arrowroot: both work to thicken the sauce
- Water: simply to dissolve the starch and achieve the right consistency
- Sesame seeds: classic garnish that adds crunch and visual flair White or black both work
- Scallions: for garnish and fresh bite Look for bright green, crisp stalks
Step by Step Instructions
- Prep and Roast the Cauliflower:
- Preheat your oven to 450 F Cut the cauliflower into bite size florets then slice so each piece has one flat side Arrange them in a single layer on a greased or parchment lined baking pan Roasting this way lets them brown more deeply on the flat side Bake on the center rack for 10 minutes
- Make the Sticky Sesame Sauce:
- While the cauliflower roasts whisk together the soy sauce sweetener rice vinegar garlic sesame oil and ginger in a small saucepan Set over medium heat and bring to a boil The heat blooms the flavors and thickens the sauce
- Thicken the Sauce:
- Stir together the cornstarch and water in a small bowl until fully dissolved As soon as the sauce boils slowly pour in the cornstarch mixture whisking constantly to avoid clumps Reduce heat to medium and cook for 2 more minutes stirring until the sauce bubbles and becomes glossy and thick Remove from heat The sauce will thicken even more as it cools
- Finish Roasting and Crisp the Cauliflower:
- Flip the cauliflower florets after the first 10 minutes and return to the oven for another 10 minutes on the center rack If you love extra crispy edges like my family does move the pan to the top rack for the final 1 to 2 minutes and broil Keep an eye so they do not burn
- Sauce and Garnish:
- Pour the hot sticky sesame sauce evenly over the roasted cauliflower Toss gently to coat Arrange on a serving dish Sprinkle with sesame seeds and sliced scallions for extra crunch and a burst of fresh flavor

Sesame oil is my favorite ingredient by far The nutty aroma always makes the whole kitchen smell like a cozy restaurant I still remember my daughter sneaking bites straight off the sheet pan during dinner prep and giggling about sticky fingers
Storage Tips
Store any leftovers in an airtight container in the fridge for up to three days Reheat in the oven or in a hot skillet to restore crispness Avoid microwaving if you want to keep the edges crispy Sticky sesame sauce can be made ahead and kept chilled for up to a week
Ingredient Substitutions
