Filetes de coliflor asados
Thick planks of cauliflower brushed with a smoky spice oil and roasted at high heat until the edges caramelize and the core turns silky and tender. Cutting straight through the stem keeps each slab in one piece, and a hot sheet pan plus one mid-roast flip gives you deep browning on both sides instead of steamed, pale florets. It is a hearty, knife-and-fork vegan main that comes together with pantry spices in about 45 minutes.
Heat the oven to 220 C (425 F) with a rack in the lower third. Pull the leaves off 2 large heads of cauliflower, trim the stem flat but leave the core intact, then stand each head upright and cut two 4 cm (1.5 inch) slabs straight through the center of the core; save the loose side florets for another use or roast them alongside. Stir 60 ml (1/4 cup) olive oil with smoked paprika, garlic powder, cumin, salt, and pepper, brush the paste generously over both sides of each steak, and lay them on a parchment-lined rimmed baking sheet. Roast 15 minutes, flip carefully with a thin metal spatula, and roast another 12 to 15 minutes until the edges are deeply browned and a knife slides through the core with no resistance. Finish with a squeeze of lemon, chopped parsley, and flaky salt.
- Cut straight through the center of the core — only the middle slices hold together as steaks, so plan on 2 steaks per head.
- Brush the spice oil on rather than drizzling; an even coat on both flat faces is what builds the browned, crusty surface.
- Flip only once, halfway through, using a thin spatula under the whole steak — extra flipping is when they break apart.

Ingredientes
Cauliflower
- large heads cauliflower, about 900 g / 2 lb each, with tight, unblemished heads
Spice oil
- 60 ml extra-virgin olive oil
- 2 g smoked paprika, sweet paprika works too
- 3 g garlic powder
- 1 g ground cumin
- 6 g kosher salt, use a scant 3/4 tsp if using fine sea salt
- 1 g freshly ground black pepper
To finish
- lemon, cut into wedges
- 8 g chopped fresh flat-leaf parsley
- 1 g flaky sea salt, optional, for serving
Elaboración
- PASO01
Set a rack in the lower third of the oven and heat it to 220 C (425 F). Line a large rimmed baking sheet with parchment paper. The lower rack position puts the pan closer to the heat source, which helps the underside of the steaks brown instead of steam.
- PASO02
Pull off the outer leaves from both heads and trim the stem end flat so each head stands upright, but do not cut out the core — it is the spine that holds every steak together.
- PASO03
Stand one head on its trimmed base. Slice off the rounded left and right sides (about 2.5 cm / 1 inch from each edge), then cut the center section into two slabs about 4 cm (1.5 inches) thick, cutting straight down through the middle of the core. Repeat with the second head so you have 4 steaks. Save the loose florets from the sides for another meal, or tuck them onto the pan around the steaks.
- PASO04
In a small bowl, stir together the olive oil, smoked paprika, garlic powder, cumin, kosher salt, and black pepper until it forms a loose, brick-red paste.
- PASO05
Arrange the steaks in a single layer on the prepared pan. Brush the spice oil over both flat sides of each steak, working it into the crevices, and use it all — the oil is what carries heat into the surface and builds a crust. Leave space between the steaks so air can circulate.
- PASO06
Roast for 15 minutes, until the underside is spotted deep golden brown when you peek with a spatula.
- PASO07
Slide a thin metal spatula fully under each steak and flip it in one confident motion. Roast another 12 to 15 minutes, until the edges are dark and caramelized and a paring knife slips through the thickest part of the core with no resistance.
- PASO08
Transfer the steaks to plates, squeeze lemon over the top, and scatter with parsley and a pinch of flaky salt. Serve hot, while the edges are still crisp.
Make ahead
You can cut the steaks and mix the spice oil up to 1 day ahead. Wrap the raw steaks tightly or store them in an airtight container in the fridge, and keep the spice oil covered at room temperature (give it a stir before using). Brush and season just before roasting — salting too far ahead draws out moisture and slows browning.
Storage
Refrigerate leftovers in an airtight container for up to 4 days. Reheat on a baking sheet at 200 C (400 F) for 8 to 10 minutes, or in a dry skillet over medium heat, to bring back the browned edges — the microwave makes them soft and watery. Freezing is not recommended; thawed cauliflower turns mushy and weeps liquid.
Variations
Parmesan-crusted (vegetarian)
In the last 5 minutes of roasting, sprinkle each steak with about 15 g (2 tbsp) finely grated Parmesan and return to the oven until melted and golden. Adds dairy, so it is vegetarian rather than vegan — use a plant-based hard cheese to keep it vegan.
Harissa and tahini
Swap the spice paste for 2 tbsp harissa whisked into the olive oil, then drizzle the finished steaks with a sauce of 60 g (1/4 cup) tahini thinned with lemon juice and water. Still vegan; note that tahini adds sesame for anyone tracking allergens.
Curry-spiced
Replace the paprika and cumin with 2 tsp curry powder and 1/2 tsp ground turmeric. Finish with cilantro instead of parsley and a spoonful of coconut yogurt on top.

Preguntas frecuentes
Why does my cauliflower steak fall apart when I flip it?
Almost always it is one of three things: the core was trimmed away, the slices came from the outer edges of the head, or the steak was moved too often. Cut straight through the center of the core so the stem holds the florets together, take only the two middle slices from each head, and flip just once with a thin spatula slid fully underneath.
How thick should I cut a cauliflower steak?
Aim for 2.5 to 4 cm (1 to 1.5 inches). Thinner slices crisp faster but break easily and can dry out before they brown; thicker ones hold together well but need a few extra minutes, so check the core with a paring knife before pulling them.
Can I grill cauliflower steaks instead of roasting them?
Yes. Brush them with the same spice oil and grill over direct medium heat for 5 to 6 minutes per side, then move to indirect heat, cover, and cook another 8 to 10 minutes until the core is tender. A grill basket or a wide spatula makes flipping safer.
How do I know when a cauliflower steak is done?
Look for two signals: the edges and flat faces should be deeply browned, and a paring knife should slide through the thickest part of the core with no resistance. If it browns before it is tender, tent loosely with foil and give it 5 more minutes.
What should I do with the leftover florets from the sides?
Each head only yields two true steaks, so you will have a pile of loose florets. Toss them with a little extra oil and salt and roast them on the same pan (they finish in about 20 minutes), or save them raw for stir-fries, soup, or cauliflower rice within 3 to 4 days.
