Ingredients for Roasted Garlic and Parmesan Cauliflower
To create this roasted cauliflower masterpiece, you’ll need the following ingredients:
- 1 large head of cauliflower, cut into florets
- 2 tablespoons olive oil
- 4 cloves garlic, minced
- 1/2 cup grated Parmesan cheese
- Salt and black pepper, to taste
- 1 teaspoon dried oregano or Italian seasoning
- Fresh parsley, chopped (optional, for garnish)

These ingredients are simple, yet they come together to create a perfect balance of flavor. Roasting cauliflower in the oven helps caramelize its natural sugars, making it both tender and crispy at the same time.
Step-by-Step Instructions
Making roasted garlic and Parmesan cauliflower is quick and easy! Here’s how you can do it:
Step 1: Preheat the Oven
Start by preheating your oven to 400°F (200°C). A high heat is crucial for achieving that delicious caramelization on the cauliflower.
Step 2: Prepare the Cauliflower
Cut the cauliflower into florets. Try to make them evenly sized so they cook at the same rate. If you have any extra large pieces, feel free to slice them in half to ensure uniform cooking. The cauliflower florets are the perfect bite-sized pieces to roast and get crispy.
Step 3: Season the Cauliflower
Place the cauliflower florets in a large bowl. Add olive oil, minced garlic, salt, black pepper, and oregano or Italian seasoning. Toss everything together, making sure each piece of cauliflower is coated with the seasoning. The olive oil will help the garlic and spices stick to the florets and promote a crispy texture during roasting.
Step 4: Spread on a Baking Sheet
Once the cauliflower is seasoned, spread the florets out evenly in a single layer on a baking sheet. You want the florets to have enough space to roast properly and get those nice crispy edges. Avoid overcrowding the pan to ensure that the cauliflower roasts, not steams.
Step 5: Roast in the Oven
Roast the cauliflower in the oven for 25–30 minutes. Be sure to stir halfway through the roasting time to ensure an even cook. The cauliflower should turn a golden brown color and become tender when pierced with a fork. If you like your cauliflower extra crispy, you can leave it in the oven for an additional 5 minutes.
Step 6: Add Parmesan and Garnish
Once the cauliflower is roasted to perfection, remove it from the oven. While it’s still hot, sprinkle the grated Parmesan cheese over the florets. The warmth of the cauliflower will cause the cheese to melt slightly, creating a delicious cheesy crust. Garnish with fresh parsley for a pop of color and an extra touch of flavor.
Step 7: Serve and Enjoy
Serve your roasted garlic and Parmesan cauliflower warm. It’s the perfect side dish for almost any main course, including grilled meats, pasta dishes, or even as a snack on its own.

Tips for the Perfect Roasted Garlic and Parmesan Cauliflower
To ensure your roasted garlic and Parmesan cauliflower is perfectly cooked every time, here are some tips:
- Don’t Skip the Garlic: The minced garlic is what infuses the cauliflower with a rich, savory flavor. Make sure to use fresh garlic for the best results.

- Add Lemon Zest: A touch of fresh lemon zest can add a zesty flavor that pairs beautifully with the garlic and Parmesan.
- Add Other Veggies: Cauliflower is wonderful on its own, but you can add other vegetables, such as broccoli, carrots, or Brussels sprouts, to the roasting pan for a medley of flavors.
FAQs about Roasted Garlic and Parmesan Cauliflower
