Cauliflower florets are tossed with olive oil, garlic powder, onion powder, smoked paprika, cumin and cayenne, then roasted on a sheet pan at 425°F until tender and golden. A squeeze of lemon and a handful of parsley finish it. The recipe serves 4 as a side, takes 40 minutes and has about 4 grams of carbohydrates per serving.

Save this recipe for later:

The high oven heat browns the edges of the florets, and the spice mix turns a plain vegetable into something with smoke, warmth and a little heat.

The Spice Mix

  • Cauliflower (1 medium head): cut into bite-sized florets so they cook evenly.
  • Olive oil (3 tablespoons): helps the spices stick and carries their flavor as the cauliflower roasts.
  • Garlic powder (1 teaspoon) and onion powder (1 teaspoon): savory depth.
  • Smoked paprika (1 teaspoon) and ground cumin (1 teaspoon): a warm, smoky base.
  • Cayenne pepper (1/2 teaspoon): adjust it to taste for more or less heat.
  • Salt and pepper: to taste.
  • Fresh parsley (2 tablespoons, chopped) and lemon wedges: for garnish and serving. The lemon brightens the spices.

Roasting It

Preheat the oven to 425°F (220°C). Put the florets in a large bowl with the olive oil and all the spices and toss until evenly coated. Spread them in a single layer on a baking sheet lined with parchment paper. A single layer matters, because crowded florets steam instead of roasting.

Roast for 25-30 minutes, stirring halfway through, until the cauliflower is tender and golden brown. Garnish with parsley and serve with lemon wedges on the side. A squeeze of lemon just before eating adds a sharp contrast.

Tips

  • Use fresh spices. If you have whole spices, grind them just before use.
  • Watch the oven. If yours runs hot, shorten the time a little. Aim for golden brown and tender.
  • Try other pans. A standard baking sheet works well, and a cast iron skillet can add depth of flavor.

Variations

  • Parmesan: sprinkle grated Parmesan over the cauliflower during the last 5 minutes of roasting so it melts into a crust.
  • Other spices: curry powder gives an Indian-style flavor, Italian seasoning a Mediterranean one, and chili powder adds more kick.
  • More vegetables: mix in bell peppers, zucchini or broccoli.

What to Serve With It

Grilled chicken or fish go well with it, as does a simple green salad with an olive oil dressing. Sparkling water with lemon or herbal tea suits it as a drink.

FAQ

Can I use frozen cauliflower?

Yes. Thaw it and drain it well before seasoning, so it browns instead of steaming.

How long do leftovers keep?

Up to 3 days in an airtight container in the refrigerator. Reheat in the oven or microwave. The oven re-crisps it best.

Which other spices work?

Curry powder, Italian seasoning and chili powder all work.
