This Italian roasted cauliflower recipe is a delightful way to transform a simple vegetable into a flavorful side dish. The combination of olive oil, garlic powder, and dried oregano brings out the natural sweetness of the cauliflower, while a sprinkle of parmesan cheese adds a savory finish.

Most of the ingredients in this recipe are common pantry staples, but you might need to pick up a fresh cauliflower if you don't have one on hand.

The parmesan cheese is optional but highly recommended for an extra layer of taste.

Ingredients For Italian Roasted Cauliflower Recipe
Cauliflower: The star of the dish, cut into florets for even roasting.
Olive oil: Helps to coat the cauliflower and adds a rich flavor.
Garlic powder: Provides a subtle garlic taste without the hassle of peeling and chopping fresh garlic.
Dried oregano: Adds a classic Italian herb flavor to the dish.
Salt: Enhances all the other flavors.
Black pepper: Adds a bit of heat and depth.
Parmesan cheese: Optional, but adds a savory, cheesy finish to the roasted cauliflower.
Technique Tip for This Recipe
To achieve perfectly roasted cauliflower, make sure to cut the florets into uniform sizes. This ensures even cooking and prevents some pieces from burning while others remain undercooked. Additionally, don't overcrowd the baking sheet; give each floret enough space to allow for proper browning and crisping. If necessary, use two baking sheets to avoid steaming the cauliflower instead of roasting it.
Suggested Side Dishes
Alternative Ingredients
cauliflower - Substitute with broccoli: Broccoli has a similar texture and can be roasted in the same way, providing a slightly different but equally delicious flavor.
olive oil - Substitute with avocado oil: Avocado oil has a high smoke point and a neutral flavor, making it a good alternative for roasting.
garlic powder - Substitute with fresh minced garlic: Fresh minced garlic provides a more intense and aromatic garlic flavor compared to garlic powder.
dried oregano - Substitute with dried thyme: Dried thyme offers a slightly different but complementary herbal note that works well with roasted vegetables.
salt - Substitute with sea salt: Sea salt can provide a more complex flavor profile and a slightly different texture.
black pepper - Substitute with white pepper: White pepper has a milder flavor and can be used to add a subtle heat without altering the color of the dish.
grated parmesan cheese - Substitute with nutritional yeast: Nutritional yeast offers a cheesy, nutty flavor and is a great vegan alternative to parmesan cheese.

How to Store or Freeze This Dish
- Allow the roasted cauliflower to cool completely at room temperature before storing.
- Transfer the cooled cauliflower florets into an airtight container. This helps maintain their flavor and texture.
- Store the container in the refrigerator for up to 4 days. Reheat in the oven or microwave before serving to regain some of the crispiness.
- For freezing, place the cooled cauliflower on a baking sheet in a single layer. This prevents the florets from sticking together.
- Freeze the baking sheet for 1-2 hours until the cauliflower is solid.
- Transfer the frozen cauliflower florets into a freezer-safe bag or container, removing as much air as possible to avoid freezer burn.
- Label the container with the date and store in the freezer for up to 3 months.
- To reheat, preheat your oven to 400°F (200°C). Spread the frozen cauliflower on a baking sheet and roast for 15-20 minutes, or until heated through and crispy.
- Alternatively, you can reheat the frozen cauliflower in a microwave-safe dish, covering it loosely with a microwave-safe lid or plastic wrap. Heat on high for 3-5 minutes, stirring halfway through.
How to Reheat Leftovers
Oven Method: Preheat your oven to 375°F (190°C). Spread the leftover cauliflower on a baking sheet in a single layer. Cover with aluminum foil to prevent drying out. Heat for about 10-15 minutes, or until warmed through. For a crispier texture, remove the foil in the last 5 minutes of reheating.
Stovetop Method: Heat a non-stick skillet over medium heat. Add a small amount of olive oil or butter to the pan. Add the leftover cauliflower and sauté for about 5-7 minutes, stirring occasionally, until heated through and slightly crispy.
Microwave Method: Place the leftover cauliflower in a microwave-safe dish. Cover with a microwave-safe lid or a damp paper towel to retain moisture. Microwave on high for 1-2 minutes, stirring halfway through. Continue heating in 30-second intervals if needed, until hot.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the leftover cauliflower in the air fryer basket in a single layer. Heat for about 5-7 minutes, shaking the basket halfway through, until the cauliflower is heated through and crispy.
Toaster Oven Method: Preheat your toaster oven to 375°F (190°C). Spread the leftover cauliflower on the toaster oven tray. Heat for about 10-12 minutes, or until warmed through, stirring halfway for even heating.
