- Heat the oven: Set oven to 425°F. Line a large sheet pan with parchment if you want easy cleanup.
- Dry and season: Pat cauliflower dry. Toss florets in a bowl with olive oil, salt, pepper, garlic powder, and smoked paprika.
- Roast hot and spaced out: Spread cauliflower in a single layer with space between pieces. Roast 20 to 25 minutes, flipping once halfway, until browned at the edges and tender-crisp.
- Finish with brightness: Zest a little lemon over the top, add parsley, and squeeze lemon juice right before serving.
- Make it yours: Add Parmesan while hot, or drizzle tahini, or hit it with hot sauce. Taste and adjust salt. Cauliflower loves a final seasoning check.

More Healthy, Easy Cauliflower Ideas
If you want variety without having to reinvent dinner, you have two options: start with the roasted base above and switch up the sauce, or use the same cauliflower in a totally different way (rice it, mash it, simmer it) when you want a change of texture.
1) Buffalo Cauliflower Bites (Baked)
Roast cauliflower as written, then toss the hot florets with 3 tbsp buffalo sauce and 1 tbsp melted butter or olive oil. Return to oven for 5 minutes to set the sauce. Serve with a yogurt ranch dip.
2) Cauliflower “Fried Rice” (15 minutes)
How to make cauliflower rice: Cut cauliflower into chunks, then pulse in a food processor until it looks like rice (do not over-blend into mush). No processor? Use the large holes of a box grater. Or buy a bag of pre-riced cauliflower.
Sauté 1 tbsp oil, add 2 cups cauliflower rice, cook 3 to 4 minutes, then add frozen peas and carrots, scrambled egg (optional), and a splash of low-sodium soy sauce. Finish with sesame oil and green onion.
3) Creamy Cauliflower Mash
Simmer florets in salted water until very tender, drain well, then blend with 2 tbsp Greek yogurt or milk, 1 tbsp butter or olive oil, garlic, salt, and pepper. Add Parmesan if you want it extra cozy.
4) Lemon Garlic Cauliflower Soup
Sauté onion and garlic, add cauliflower and broth, simmer until soft, blend until smooth, then finish with lemon juice and black pepper. A drizzle of olive oil on top makes it feel restaurant-y.
5) Cauliflower Tacos
Roast florets with cumin and chili powder. Stuff into warm tortillas with slaw, salsa, and a lime-y yogurt sauce.
