Ingredients
For the Cauliflower
1 large head cauliflower, about 2 lb (900 g)
2½ tablespoons extra-virgin olive oil
3 cloves garlic, finely minced
1 teaspoon paprika
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1/2 teaspoon dried oregano
1/2 teaspoon black pepper
1/2 teaspoon salt, or to taste
1/4 teaspoon red pepper flakes, optional
1/3 cup finely grated Parmesan cheese
1 tablespoon fresh lemon juice
Optional Garnish
1 tablespoon chopped fresh parsley
1 teaspoon lemon zest
Extra Parmesan
A drizzle of olive oil
Freshly cracked black pepper
Instructions
1. Preheat the Oven
Preheat your oven to 450°F (230°C).
Place a large rimmed baking sheet inside the oven while it preheats.
A hot baking sheet helps the cauliflower begin roasting immediately and encourages better browning.
2. Prepare the Cauliflower
Remove the leaves and tough stem.
Cut the cauliflower into small-to-medium florets, keeping them relatively similar in size so they cook evenly.
Wash if needed, then dry the cauliflower extremely well.
Excess moisture will cause steaming instead of roasting.
3. Season the Cauliflower
Place the dry cauliflower florets in a large bowl.
Add:
Olive oil
Minced garlic
Paprika
Garlic powder
Onion powder
Oregano
Black pepper
Salt
Red pepper flakes, if using
Toss thoroughly until every piece is lightly coated.
4. Add to the Hot Baking Sheet
Carefully remove the hot baking sheet from the oven.
Spread the cauliflower over it in one single layer.
Make sure the florets aren’t crowded.
For extra browning, place some pieces cut-side down against the baking sheet.
5. Roast
Roast for approximately 15 minutes.
Remove the tray and flip or stir the cauliflower.
Return it to the oven and roast for another 5–10 minutes, until the edges are deeply golden and crispy and the centers are tender.
6. Add Parmesan
Sprinkle the Parmesan evenly over the roasted cauliflower.
Return to the oven for another 2–3 minutes, just until the cheese melts and becomes lightly golden.
7. Finish
Remove from the oven.
Drizzle with fresh lemon juice.
Garnish with parsley, lemon zest, additional Parmesan, and freshly cracked black pepper.
Serve immediately.

Nut & Allergen Information
Nuts
This recipe contains no peanuts or tree nuts as written.
Other Potential Allergens
Milk: Parmesan cheese
Possible cross-contact: Packaged Parmesan and seasonings may be processed in facilities that handle nuts or other allergens.
For a severe allergy, check individual product labels.
Dairy-Free Version
Simply omit the Parmesan or replace it with a dairy-free Parmesan alternative.
Vegan Version
Use dairy-free Parmesan or nutritional yeast and make sure all seasonings are vegan-friendly.
How to Make It Extra Crispy
Dry the cauliflower thoroughly. Moisture is the enemy of crispiness.
Use a very hot oven. 450°F gives the florets a good roasted exterior.
Don’t overcrowd the pan. Leave space between pieces.
Use enough oil to lightly coat the florets.
Put some flat sides directly against the pan.
Don’t cover the cauliflower while roasting.
Finish under the broiler for 1–2 minutes if you want extra-dark crispy edges. Watch carefully so it doesn’t burn.

Frequently Asked Questions
Q: Why isn’t my roasted cauliflower crispy?
The most common causes are excess moisture, overcrowding the pan, or using an oven temperature that is too low. Dry the cauliflower thoroughly and spread it into one layer.
Q: Should I boil cauliflower before roasting?
No. For this quick recipe, roast the cauliflower directly. Pre-boiling adds moisture and can make it harder to achieve crispy edges.
Q: Can I use frozen cauliflower?
Yes, but fresh cauliflower generally produces better crispiness. If using frozen, roast it directly from frozen and avoid overcrowding the pan.
Q: Can I make this without Parmesan?
Yes. Simply omit it. The cauliflower will still become crispy and flavorful.
Q: Can I use broccoli instead?
Yes. Broccoli works very well with the same seasoning mixture, although it may cook slightly faster.
Q: Can I prepare the cauliflower ahead of time?
You can cut and season the cauliflower several hours ahead, but keep it refrigerated and roast it shortly before serving for the best texture.
Q: Can I use an air fryer?
Yes. Air-fry the seasoned florets at approximately 400°F (205°C) for 12–16 minutes, shaking the basket halfway through. Add Parmesan during the final 2–3 minutes.
Q: Is roasted cauliflower keto-friendly?
Yes. Cauliflower is naturally low in carbohydrates, and this recipe contains only a modest amount of carbohydrates per serving.
Q: Is this recipe gluten-free?
The basic ingredients are naturally gluten-free. If preparing food for someone with celiac disease or severe gluten sensitivity, check packaged Parmesan and seasonings for gluten and cross-contact.
Q: Can I add nuts for extra crunch?
Yes. Toasted sliced almonds, chopped walnuts, or pine nuts can be added after roasting. However, these are not included in the base recipe and would change the allergen and nutrition information.
Q: How do I prevent the garlic from burning?
Finely minced garlic can brown quickly at 450°F. If your garlic tends to burn, use garlic powder during roasting and add fresh minced garlic during the final 5 minutes instead.
Q: Can I make this without olive oil?
A small amount of avocado oil or another suitable cooking oil can be substituted. Some fat is important for achieving good browning and crisp edges.
