🥘 Ingredients
- Cauliflower Head – The star of the dish. When trimmed into bite-size florets and roasted, it transforms into tender pieces with crispy edges and nutty, caramelized flavor.
- Extra Virgin Olive Oil – Coats the cauliflower to help it roast evenly and turn golden brown. A little olive oil also brings out the natural sugars in the cauliflower for deeper flavor.
- Garlic Cloves (Minced) – Four fresh garlic cloves infuse the cauliflower with bold, savory depth. Roasting mellows their bite, leaving behind warm, aromatic flavor in every piece.
- Black Pepper – Adds a mild kick and balances the savory and cheesy notes with a subtle heat.
- Sweet Paprika – Brings warm, earthy undertones and gives the cauliflower a gorgeous color while enhancing the toasty, roasted flavor.
- Red Pepper Flakes (Optional) – For those who like a little heat, these add a subtle spicy kick without overpowering the dish.
- Parmesan Cheese or Pecorino Romano (Grated) – A generous dusting of sharp, salty cheese melts into the cauliflower during the last few minutes of roasting, creating crispy, golden bits that are absolutely the best part.
- Fresh Lemon Juice (Optional) – Just a splash brightens the whole dish, cutting through the richness with a clean, citrusy finish.
- Fresh Chopped Parsley (Optional, for Serving) – Adds a pop of color and freshness to balance the roasted flavors and bring an herby lift to each bite.

🔪 Step by Step Instructions
Preheat the oven & prepare the pan: Set your oven to 425ºF (220ºC). Line a large baking sheet with parchment paper and place it in the oven to preheat—starting with a hot pan helps the cauliflower get crispy edges.
Toss the cauliflower: In a large bowl, combine cauliflower florets with extra virgin olive oil, minced garlic, salt, black pepper, sweet paprika, and red pepper flakes (if using). Toss well to coat evenly.
Roast the cauliflower: Carefully remove the hot baking sheet from the oven and arrange the seasoned cauliflower in a single layer, flat sides down when possible. Roast for 25–30 minutes, undisturbed, until golden brown and fork-tender.
Add the parmesan cheese: In the last 5 minutes of roasting, sprinkle grated parmesan cheese or Pecorino Romano over the cauliflower and return the pan to the oven until the cheese melts and turns slightly crisp.
Finish with lemon and parsley: Remove from the oven and, if desired, drizzle with fresh lemon juice. Garnish with chopped fresh parsley for a burst of color and flavor.
Serve: Plate and serve this Italian Roasted Cauliflower immediately as a great side dish for your favorite main dishes—or enjoy it on its own as a low carb, healthy snack.
👩🏼🍳 Chef's Tips
- For the crispiest edges, make sure the cauliflower is completely dry before tossing with oil and seasonings—moisture can cause steaming instead of roasting. Use a paper towel to pat the florets dry after washing.
💭 Recipe FAQs
Yes! You can roast the cauliflower up to a day in advance. Store it in an airtight container in the fridge, then reheat on a parchment paper–lined baking pan at 400ºF until warmed through and crispy again. It's just as delicious the next day!

- 1 teaspoon chili flakes optional, to taste
- ½ cup Pecorino Romano or Parmigiano Reggiano cheese, grated
- 1 tablespoon freshly squeezed lemon juice optional
- Additional grated cheese and chopped fresh Italian parsley for garnish (optional)
Instructions
- Preheat the oven: Set your oven to 425ºF (220ºC). Place a baking sheet in the oven while it preheats—this helps the cauliflower develop crispy, caramelized edges.

- Arrange on the pan: Spread the cauliflower on the hot baking sheet in a single layer, flat sides down when possible. Leave space between pieces to help them roast, not steam.

Notes
- Using a hot pan helps jumpstart caramelization—don't skip it!
