Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
• 1 medium head cauliflower, cut into florets (about 7–8 cups)
• Extra‑virgin olive oil (for roasting)
• Paprika
• Kosher salt
• Cracked black pepper
• Garlic cloves, minced
• Grated Parmesan cheese
• Juice of ½ lemon
• Fresh parsley, finely chopped

Directions

Preheat your oven to 450 °F (about 232 °C) and place a large, rimmed baking sheet on the center rack so it heats up.
Cut the cauliflower into small, evenly‑sized florets (aiming for plenty of flat surface area for browning).
In a large bowl, toss the florets with olive oil, paprika, salt, and black pepper until well coated.
Carefully remove the preheated baking sheet from the oven and spread the cauliflower in a single layer on it — don’t overcrowd the pan.
Roast for 20 to 25 minutes until the florets are tender and lightly charred, tossing once midway through.
Sprinkle the minced garlic and grated Parmesan cheese over the roasted cauliflower and return the baking sheet to the oven for 5 more minutes to melt the cheese and roast the garlic lightly.
Remove from the oven, drizzle the lemon juice over the cauliflower, sprinkle with fresh parsley, toss gently, and serve immediately.

Variations

Make it vegan: substitute the Parmesan with nutritional yeast for a cheesy flavor without dairy.
Add heat: toss in a pinch of crushed red pepper flakes along with the paprika.
Change the herb: swap the parsley for fresh dill, chives, or cilantro depending on your preference.
Bulk it up: toss the roasted cauliflower with cooked chickpeas or white beans for extra protein.
Add crunch: sprinkle toasted pine nuts or chopped walnuts just before serving for texture.

Storage/Reheating

Store any leftovers in an airtight container in the refrigerator for up to 5 days. To reheat and restore some crispiness, place the cauliflower in a 350 °F (about 175 °C) oven or an air‑fryer until warmed through. Reheating in the microwave will work but results in softer florets.

FAQs

What size should the cauliflower florets be?

Aim for small to medium‑sized florets so they cook evenly and brown nicely. If pieces are too large they may remain undercooked in the center.

Do I need to preheat the baking sheet?

Yes — preheating the baking sheet ensures the cauliflower starts to sizzle when it hits the pan, improving browning and texture.

Can I skip the garlic or use garlic powder instead?

You can skip the fresh garlic if needed, but fresh minced garlic adds a sharper, more vibrant flavor. Garlic powder would be milder and could work, but won’t deliver quite the same kick.

Is this recipe gluten‑free?

Yes — the core ingredients (cauliflower, olive oil, paprika, salt, pepper, garlic, lemon, Parmesan/par nutritional yeast) are naturally gluten‑free. Just ensure your parmesan (or substitute) is certified gluten‑free if that is a concern.

Can I make this ahead of time?

You can prep the cauliflower by cutting the florets up to 3 days ahead and storing them in the fridge. Roast them just before serving for best texture.

What if I don’t have a high‑temperature oven?

The high temperature (450 °F) helps the cauliflower caramelize and crisp. If your oven maxes out lower, you can still roast it but expect slightly less browning and a bit more cook time.

Could I use other vegetables instead of cauliflower?

Certainly — this method would also work nicely with broccoli, Brussels sprouts (halved), or even cauliflower‑broccoli mixes. Adjust cook time slightly for different veggies.

How can I serve this besides as a side dish?

You could stuff the roasted cauliflower into pita bread, tacos or burrito bowls, toss it into a grain salad, or serve over greens with a tahini or yogurt‑based dressing for a vegetarian main.

Does the Parmesan need to be added at the end?

Yes — sprinkling the Parmesan near the end preserves its flavor and prevents it from burning at high heat during the main roast phase.

What’s the best way to keep the florets from becoming soggy?

Don’t overcrowd the pan (give each floret space), use plenty of oil to promote browning, and roast at high heat. These steps help avoid steaming the cauliflower which leads to soggy texture.
