Roasted Garlic Cauliflower Steaks with Tahini

Jump to Recipe

Cauliflower steaks get a bad reputation for being boring. Cut them thick, roast them hot, and they’re anything but.

The key is a flat, direct surface against a hot sheet pan. That contact creates a proper sear in the oven, the same caramelized crust you’d get from a cast iron skillet, without the extra step.

Whole garlic cloves roast right alongside the cauliflower. By the time the steaks are done, the garlic is soft, golden, and mild enough to spread or tuck alongside each bite.

The tahini sauce is just four ingredients. It comes together in two minutes and does a lot of work on the plate.

Why You’ll Love This Recipe

• Caramelized crust forms without any frying or flipping tricks
• Roasted garlic gets soft and mild, not sharp or raw
• Tahini sauce takes under two minutes to mix together
• Works as a satisfying main or a substantial side dish

Ingredient Notes

• cauliflower: One large head yields 4 solid steaks from the center. The outer florets that fall off can be roasted alongside as a snack or side.
• tahini: Use a runny, well-stirred tahini (Soom or Seed + Mill work well). Thick, dry tahini will seize up when you add lemon juice.
• garlic: Whole cloves roast best here. If you only have pre-minced, spread it on the steaks in the last 10 minutes so it doesn’t burn.
• olive oil: Don’t skimp. The oil is what helps the cut face of each steak get color in the oven.
• lemon juice: Fresh lemon juice keeps the tahini sauce bright. Bottled works in a pinch but the flavor is flatter.
• smoked paprika: Adds a faint warmth and color to the spice rub. Regular paprika or cumin works if that’s what you have.

Ingredients

  

Cauliflower Steaks

• 1 (about 1 kg) large cauliflower head trimmed, cut into 4 steaks about 3 cm thick
• 3 tbsp olive oil
• 8 garlic cloves whole, unpeeled
• 1 tsp smoked paprika
• 1/2 tsp ground cumin
• 3/4 tsp fine sea salt
• 1/4 tsp black pepper freshly ground

Tahini Sauce

• 60 ml (1/4 cup) tahini well-stirred, runny consistency
• 2 tbsp lemon juice freshly squeezed
• 3 to 4 tbsp cold water added gradually to reach drizzling consistency
• 1/4 tsp fine sea salt
• 1 small clove garlic grated or finely minced

To Serve (optional)

• small handful fresh flat-leaf parsley roughly chopped
• 1 tsp toasted sesame seeds
• 4 lemon wedges

Method

 

Prep

1. Heat the oven to 220 C / 430 F. Place a large rimmed sheet pan on the middle rack while the oven heats.
2. Remove the outer leaves from the cauliflower. Trim the base of the stem flat so the head sits steady. Cut straight down through the center to make 4 steaks, each about 3 cm thick. Reserve any loose florets for another use or roast alongside.
3. In a small bowl, stir together the olive oil, smoked paprika, cumin, salt, and black pepper.

Roast

1. Remove the hot sheet pan from the oven carefully. Lay the cauliflower steaks flat on the pan in a single layer. Brush or spoon the spiced oil generously over both sides of each steak.
2. Scatter the whole garlic cloves around the steaks on the pan.
3. Roast for 15 minutes until the cut face is deep golden and starting to char at the edges. Flip each steak carefully using a wide spatula. Roast for another 10 minutes until the second side is browned and a fork slides through the thickest part of the stem with slight resistance.

Make the Tahini Sauce

1. While the cauliflower roasts, whisk together the tahini, lemon juice, grated garlic, and salt in a small bowl. The mixture will seize and thicken first.
2. Add cold water one tablespoon at a time, whisking after each addition, until the sauce is smooth and drizzles easily from a spoon. It should be pourable but not watery.

Serve

1. Remove the pan from the oven. Rest the steaks for 3 minutes. Squeeze the soft roasted garlic from its skin and scatter over the steaks, or serve the cloves whole alongside.
2. Arrange steaks on plates. Drizzle generously with tahini sauce. Top with chopped parsley and sesame seeds if using. Serve with lemon wedges on the side.

Notes

A preheated sheet pan is the single most important step here. It gives the cauliflower an immediate sear on contact rather than letting it sit and soften before browning.

Tips for Success

• Preheat the sheet pan in the oven so the cauliflower sears on contact, not steams.
• Cut steaks at least 3 cm thick so they hold together through roasting without falling apart.
• Pat cauliflower slices dry before oiling to help browning rather than steaming.
• Thin the tahini sauce with cold water, one tablespoon at a time, until it drizzles easily.
• Rest steaks 3 minutes off the oven before plating so moisture settles and slices stay firm.

Variations

• Add a teaspoon of harissa to the tahini sauce for a spiced, red-tinted finish.
• Top with toasted pine nuts and fresh flat-leaf parsley for texture and color contrast.
• Swap smoked paprika for za’atar in the spice rub for a more herby, Middle Eastern profile.

Storage and Reheating

Store leftover steaks flat in an airtight container in the fridge for up to 3 days. Keep the tahini sauce in a separate small jar.

Reheat steaks on a hot skillet over medium heat for 3 to 4 minutes per side, or on a sheet pan in a 200 C / 390 F oven for 8 minutes. The microwave softens the crust and makes the cauliflower watery.

The tahini sauce firms up in the fridge. Stir in a splash of cold water and whisk until it loosens before using.

Serving Suggestions

Serve as a main with warm gluten-free rosemary flatbread and a simple cucumber and tomato salad on the side. A handful of cooked chickpeas on the plate adds protein if you want a more filling meal.

For a mezze-style spread, pair with hummus, roasted cherry tomatoes, and pickled red onions alongside a chickpea lemon rice pilaf. The garlicky tahini sauce works across everything on the table.

As a side dish, these steaks sit well next to grilled salmon or lamb chops. The tahini sauce doubles as a dipping sauce for the rest of the plate.

FAQ

Why do my cauliflower steaks fall apart when I cut them?

The stem is what holds the steak together. Cut straight down through the center of the head so each slice includes a section of the core. Slices cut too far from center won’t have enough stem to stay intact.

Can I use almond butter instead of tahini for the sauce?

You can, but the flavor shifts significantly. Almond butter is sweeter and nuttier, while tahini has a savory, slightly bitter quality that balances the roasted garlic. If you use almond butter, add extra lemon juice to compensate.

Can I roast the cauliflower steaks ahead and reheat them for a dinner party?

Yes. Roast them up to 4 hours ahead, then reheat on a hot sheet pan at 200 C / 390 F for 8 minutes before serving. Make the tahini sauce fresh the same day since it only takes 2 minutes.

What protein goes well alongside roasted garlic cauliflower steaks?

Grilled lamb chops, pan-seared salmon, or a fried egg all work well. If you’re keeping it plant-based, spiced chickpeas or a turmeric garlic white bean stew on the side adds enough protein to make it a full meal.

Are roasted cauliflower steaks with tahini suitable for a gluten-free diet?

Yes, this recipe is naturally gluten-free. All the ingredients (cauliflower, olive oil, garlic, tahini, lemon, spices) contain no gluten, but check your tahini label if cross-contamination is a concern.

How do I know when the cauliflower steaks are properly roasted?

Look for a deep golden-brown color on the cut face with edges starting to darken. A fork should slide through the thickest part of the stem with just slight resistance, not mushy and not hard.
