- 1/4 Cup Honey (or maple syrup for a vegan option)
- 2 Garlic Cloves, minced
- 1/4 Cup Low sodium soy sauce or coconut aminos
- 1 tablespoon Sriracha
- 1 tablespoon Hoisin Sauce
- 1 teaspoon Gluten-free flour or cornstarch
Step-by-Step Instructions

- Sprinkle the florets with garlic salt, salt, and pepper, then use your hands to toss them thoroughly until every piece is coated.
- Bake in the preheated oven for 15 to 20 minutes, or until the cauliflower starts to turn golden brown on the edges.
- While the cauliflower is roasting, combine the honey, minced garlic, soy sauce, sriracha, hoisin sauce, and cornstarch in a small saucepan.
- Place the saucepan over medium heat and whisk frequently for about 4 to 5 minutes until the sauce thickens into a sticky glaze.
- Once the cauliflower is finished baking, remove it from the oven and let it cool for just a few minutes.
- Pour the thickened sauce over the cauliflower and toss until fully coated, then garnish with sliced green onions and sesame seeds before serving.

Expert Tips / Pro Tips
To get the best results with your Sweet Spicy Baked Cauliflower, ensure you cut the florets into even sizes so they cook at the same rate. If you find your cauliflower isn’t getting as crispy as you like in the oven, try not to overcrowd the pan; air needs to circulate around each floret to create those browned edges. For the sauce, using cornstarch is highly recommended over flour as it results in a clearer, stickier glaze that clings perfectly to the vegetables.
Variations & Substitutions
If you are following a strictly vegan diet, you can easily substitute the honey for maple syrup or agave nectar. For those with gluten sensitivities, ensure you use coconut aminos instead of soy sauce and a certified gluten-free cornstarch. If you prefer even more heat, feel free to double the amount of Sriracha or add a pinch of red pepper flakes to the sauce. You can also make this recipe in an air fryer by cooking the seasoned florets at 400F for 22 to 25 minutes, tossing halfway through.
Serving Suggestions
This Sweet Spicy Baked Cauliflower pairs beautifully with a wide variety of main courses. Serve it alongside a Garlic Beef Tenderloin Roast or a Lemon Garlic Oven-Roasted Whole Chicken for a complete meal. It also works wonderfully as a vegetarian main dish when served over a bed of jasmine rice or quinoa. For a fun appetizer spread, serve it with other finger foods like honey garlic air fryer tofu or shrimp cauliflower fried rice.
Storage, Freezing & Reheating
Store any leftover cauliflower in an airtight container in the refrigerator for up to 5 days. While you can freeze roasted cauliflower, the texture may become softer upon thawing, so it is best enjoyed fresh. To reheat and maintain some of the crispiness, place the florets back in the oven at 350F or in an air fryer for 3 to 5 minutes until warmed through. Avoid microwaving if possible, as this will make the cauliflower soggy.

FAQ
Can you eat cauliflower on keto?
Yes, cauliflower is a very popular low-carb vegetable used in keto diets. However, because this specific recipe uses honey and hoisin sauce, the sugar content is higher. For a keto-friendly version, you would need to use a sugar-free sweetener and a keto-approved thickener.
Why do you soak cauliflower before cooking?
Soaking cauliflower in salted water before cooking is a great way to ensure all debris and tiny insects are removed from the tight crevices of the florets. Just be sure to dry it thoroughly before roasting so it can get crispy.
Why is my roasted cauliflower not crispy?
If your cauliflower is soggy, it is likely because the pan was overcrowded, which causes the vegetable to steam rather than roast. Make sure the florets are in a single layer with space between them.
How do I make the sauce thicker?
The key to a thick, sticky sauce is the cornstarch and the simmering time. Ensure you whisk the sauce over medium heat until it bubbles and visibly thickens before tossing it with the cauliflower.
