Garlic Parmesan Roasted Cauliflower is a simple dish. The main star is the cauliflower. You want one big head of it, cut into small florets. This helps it roast evenly.
Next, we use olive oil. Three tablespoons give the cauliflower a nice shine and help the seasonings stick. Garlic is key here. Four cloves, minced, add bold flavor to the dish.
Now, we need some seasonings. Onion powder brings a sweet touch that pairs well with the garlic. Smoked paprika adds warmth and a hint of smoke.
Finally, we can’t forget the cheese! A half-cup of grated Parmesan gives a salty and creamy finish. For garnish, two tablespoons of fresh parsley add a pop of color and freshness to your dish.
This mix of ingredients creates a tasty side dish. Each bite is full of flavor and texture. You can enjoy it with many meals or as a snack!

Step-by-Step Instructions
Preparation Steps
1. Preheat your oven to 425°F (220°C). This high heat helps the cauliflower get crispy.
2. Take a large head of cauliflower and cut it into florets. You want them to be similar in size for even cooking.
3. In a large bowl, combine the cauliflower florets with 3 tablespoons of olive oil, 4 minced garlic cloves, 1 teaspoon of onion powder, 1 teaspoon of smoked paprika, ½ teaspoon of salt, and ½ teaspoon of black pepper.
4. Toss everything well. Make sure each floret is nicely coated in the oil and seasonings.
Roasting Process
1. Spread the cauliflower mixture in a single layer on a baking sheet. I like to use parchment paper for easy cleanup.
2. Roast the cauliflower in the preheated oven for 25 minutes. Be sure to stir halfway through. This helps it cook evenly and get that nice char.
Final Touch
1. After 25 minutes, take the baking sheet out of the oven.
2. Sprinkle ½ cup of grated Parmesan cheese over the roasted cauliflower.
3. Return the baking sheet to the oven for another 5 minutes. This melts the cheese and makes it bubbly and delicious.
Tips & Tricks
Ensuring Even Cooking
To get that perfect roast, stir your cauliflower halfway through cooking. This helps all sides brown nicely. I also recommend lining your baking sheet with parchment paper. It makes cleanup so much easier and prevents sticking.
Perfecting Flavor
You can adjust the garlic to suit your taste. If you love garlic, add an extra clove. If you’re not a fan, use less. Cheese is easy to switch too. Try using a different cheese like cheddar or a dairy-free option if you prefer.
Serving Suggestions
This dish pairs well with many main courses. Try it with grilled chicken or fish. It also makes a great snack or side for any meal. You can enjoy it alone or as a colorful addition to a salad.
Pro Tips
- Choose the Right Cauliflower: Select a cauliflower head that is firm and has tightly packed florets for the best texture and flavor.
- Customize the Seasoning: Feel free to add your favorite spices like cumin or chili powder for an extra kick.
- Don’t Skip the Parchment Paper: Lining your baking sheet with parchment paper prevents sticking and ensures easy cleanup.
- Storage Tips: Store any leftovers in an airtight container in the refrigerator for up to 3 days; reheat in the oven for best results.

Variations
Dietary Adjustments
You can easily make a vegan version of this dish. Simply replace Parmesan cheese with nutritional yeast. This will give it a cheesy flavor without any dairy. Nutritional yeast is a great choice for vegans. It adds a nice taste and is full of nutrients.
If you need to keep it gluten-free, you’re in luck! All the ingredients in this recipe are naturally gluten-free. Just make sure your Parmesan cheese is gluten-free. Most brands are, but it’s always good to check.
Flavor Twists
To spice things up, try adding other spices. Cumin or chili flakes can add a nice kick. If you like heat, chili flakes are perfect. Just sprinkle a little on the cauliflower before roasting.
You can also add more veggies. Carrots or bell peppers work well. Chop them up and toss them in with the cauliflower. This adds color and extra flavor to the dish.
Cooking Methods
Air frying is a fun way to cook this dish. It makes the cauliflower crispy in less time. Set your air fryer to about 380°F (193°C). Cook for about 15 minutes, shaking halfway through.
Grilling is another tasty option. It gives the cauliflower a smoky flavor. Just toss the florets in olive oil and seasonings. Then, place them on a grill basket over medium heat. Grill for about 10-12 minutes, turning until they are tender and charred.
Storage Info
Refrigeration
To store leftover Garlic Parmesan Roasted Cauliflower, let it cool down first. Place it in an airtight container. This keeps it fresh. It stays good in the fridge for about 3 to 5 days. When you want to eat it again, just take it out and reheat.
Freezing Tips
You can freeze roasted cauliflower for later use. First, let it cool completely. Then, spread it on a baking sheet in a single layer. Freeze for about an hour. Once frozen, transfer it to a freezer bag. This helps keep the texture. Garlic Parmesan Roasted Cauliflower can last in the freezer for up to 3 months. When you want to eat it, thaw it in the fridge overnight.
Reheating Options
To keep the texture nice, the oven is best for reheating. Preheat it to 350°F (175°C). Place the cauliflower on a baking sheet and heat for about 10 to 15 minutes. If you’re short on time, you can use the microwave. Heat it in short bursts, checking often to avoid sogginess. Enjoy your tasty dish again!
