Roasted cauliflower is one of those magical dishes that transforms a humble vegetable into a deliciously savory delight. With its crispy edges and tender interior, it’s hard to believe something so simple can pack such a flavor punch. Whether you’re looking to add a healthy side to your dinner table or serve up a tantalizing appetizer, this roasted cauliflower recipe is sure to impress. The combination of extra-virgin olive oil, fresh herbs, and a sprinkle of cheese elevates this dish to new heights, making it a favorite for both casual family meals and elegant gatherings.
Why This Roasted Cauliflower Stands Out

What makes this roasted cauliflower recipe a standout is its simplicity and the depth of flavor you can achieve with just a few high-quality ingredients. The key here is roasting the cauliflower at a high temperature, which brings out its natural sweetness while creating a delightful caramelization. The addition of lemon zest adds a bright note, and the fresh parsley brings a pop of color and freshness that complements the dish beautifully. Topped with grated Parmesan cheese, this roasted cauliflower becomes an irresistible side that you’ll want to make again and again.
The Ingredient Lineup
- 1 medium cauliflower – The star of the show, providing a hearty base.
- Extra-virgin olive oil – For drizzling, adding richness and flavor.
- Sea salt – Enhances the natural flavors of the cauliflower.
- Freshly ground black pepper – Adds a hint of spice and depth.
- Zest of 1 lemon – Brightens the dish with a fresh citrusy note.
- 1 cup chopped fresh parsley – Offers freshness and a vibrant green color.
- Grated Parmesan cheese – For a savory finish and umami flavor.
Must-Have Equipment
- Baking sheet – Enables even roasting and easy cleanup.
- Sharp knife – For cutting the cauliflower into florets.
- Mixing bowl – Perfect for tossing the cauliflower with oil and seasonings.
- Microplane or zester – For grating the lemon zest.
Cook Roasted Cauliflower Like This

Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). A hot oven is crucial for achieving that crispy texture.
Step 2: Prepare the Cauliflower
Rinse the cauliflower under cold water and remove the leaves. Cut the cauliflower into bite-sized florets, ensuring they are roughly the same size for even cooking.
Step 3: Season the Cauliflower
In a large mixing bowl, toss the cauliflower florets with a generous drizzle of extra-virgin olive oil. Sprinkle with sea salt and freshly ground black pepper. Make sure each floret is well-coated to ensure maximum flavor.
Step 4: Roast in the Oven
Spread the seasoned cauliflower in a single layer on the baking sheet. Roast for about 25-30 minutes, or until the edges are golden brown and the florets are tender. Halfway through, give them a stir to ensure even roasting.
Step 5: Add the Finishing Touches
Once roasted, remove the cauliflower from the oven. Immediately sprinkle with lemon zest and toss in the chopped parsley. Finally, finish with a generous shower of grated Parmesan cheese while the cauliflower is still warm, allowing it to melt slightly.
Low-Carb/Keto Alternatives

- Use nutritional yeast instead of Parmesan cheese for a dairy-free alternative that still offers a cheesy flavor.
- Experiment with different seasonings, such as garlic powder or smoked paprika, to add complexity without adding carbs.
- Serve it as a base for a keto-friendly bowl with your choice of protein and low-carb veggies.
If You’re Curious
Roasted cauliflower is not only delicious but also packed with nutrients. Cauliflower is high in fiber and vitamins C, K, and B6, making it a healthy addition to any meal. Plus, its versatility means you can customize it with different seasonings or sauces to suit your taste. For a spicy kick, try adding crushed red pepper flakes before roasting!
Store, Freeze & Reheat
Leftover roasted cauliflower can be stored in an airtight container in the fridge for up to 3 days. To freeze, place the cooled cauliflower in a freezer-safe bag, removing as much air as possible. It can be frozen for up to 2 months. To reheat, simply toss it back in the oven at 350°F (175°C) until warmed through, or microwave for a quicker option. Keep in mind that reheating in the oven will help retain its crispy texture better than the microwave.
