This bold, flavor-packed full roasted cauliflower is coated in a smoky-spicy sriracha sauce and roasted until caramelized and crispy. Finished with tangy lemon and nutty Parmesan, it’s a show-stopping vegetarian main or side dish.
Why You’ll Love This
This roasted cauliflower is one of my favorite side dishes because it’s so easy to make – just mix the ingredients together and bake. The combination of Montreal Steak Spice and fresh cilantro generates layers of smoky, savory flavor, while freshly grated Parmesan cheese is baked at high temperatures to create a delectable golden brown crunch. You can quickly mix up excellent flavor combinations with only the seasonings you usually have on hand: lemon, olive oil and hot pepper sauce!
It can also be a veggie lover’s choice by simply omitting the cheese. And it’s gluten-free, making it acceptable for practically any dietary need.

Tips for Perfectly Roasted Cauliflower
- Choose a variety that has a white surface with no browning and firm florets for the best roasted flavor.
- Soak cauliflower in salted water for 10 minutes before roasting to remove impurities
- Upgrade the flavor with specialty sauces – try the Southeast Asian Dipping Sauce (sriracha + honey + fish sauce).
- Sprinkle fresh minced garlic during the last 5 minutes of grilling to bring out the aroma.

Storing whole roasted cauliflower
Although fresh cauliflower is the best, you can preserve leftovers if necessary. Before moving the cauliflower florets to a container, allow them to cool completely.
- Refrigerate: Store leftover cauliflower in an airtight jar in the refrigerator for up to three days for best results. And you need to line the bottom with paper towels to reduce moisture during refrigeration.
- Freeze: Store in a ziplock bag for up to a month for a weekday after-work supper, but not suggested for too long.
- Reheat: To preserve crispiness, reheat cauliflower in an oven set to 400 degrees Fahrenheit for 8 to 10 minutes. Avoid using the microwave if not necessary, as it will cause the cauliflower to soften.
