Directions

Step 1: Prepare the Cauliflower

I begin by removing the outer leaves from the cauliflower while keeping the central core intact. I trim the bottom of the stem slightly so the cauliflower sits flat on my cutting board.

Using a sharp knife, I cut the cauliflower vertically through the core into thick wedges, approximately 1½–2 inches wide. I make sure each wedge includes part of the core to help hold the florets together during grilling.

I save any loose florets that fall away and grill them alongside the wedges.

Step 2: Prepare the Spice Marinade

In a small bowl, I combine the olive oil, smoked paprika, ground cumin, ground coriander, garlic powder, salt, black pepper, and lemon juice.

I whisk everything together until the spices are evenly distributed throughout the oil.

I love how this simple marinade adds warmth, color, and a slightly smoky flavor to the cauliflower.

Step 3: Season the Cauliflower

I arrange the cauliflower wedges on a large plate or baking tray and brush both sides generously with the spice marinade.

I make sure the seasoning reaches between the florets so every bite develops plenty of flavor.

I let the cauliflower rest for about 5–10 minutes while I prepare the grill.

Step 4: Grill the Cauliflower Wedges

I preheat my grill or grill pan to medium heat, approximately 375–400°F (190–200°C), and lightly oil the grates to prevent sticking.

I carefully place the cauliflower wedges on the grill and cook them for about 6–8 minutes on each side, turning gently with a wide spatula.

Once I see beautiful grill marks, I move the wedges to a cooler part of the grill, close the lid, and continue cooking for another 5–10 minutes until the centers are fork-tender.

If I use a grill pan, I cover it briefly or finish the wedges in a 400°F (200°C) oven to ensure the cauliflower cooks through without burning.

Step 5: Prepare the Tahini Yogurt Sauce

While the cauliflower cooks, I prepare the creamy tahini yogurt sauce.

In a medium bowl, I combine the Greek yogurt, tahini, lemon juice, grated garlic, olive oil, salt, and optional cumin.

I whisk everything until smooth and creamy, gradually adding cold water until I reach a thick but spreadable consistency.

I taste the sauce and adjust the lemon juice or salt as needed. I prefer a slightly tangy sauce because it balances the smoky cauliflower beautifully.

Step 6: Make the Sumac Onions

I place the thinly sliced red onion in a bowl and add the ground sumac, lemon juice, olive oil, and salt.

Using clean hands or a spoon, I gently massage the onions for about one minute to soften them and distribute the seasoning.

I stir in the chopped parsley and let the mixture rest for 10–15 minutes.

I love how the onions become slightly softer and develop a bright, tangy flavor that complements the creamy sauce.

Step 7: Assemble the Dish

I spread a generous layer of tahini yogurt sauce across a large serving platter, using the back of a spoon to create decorative swirls.

I carefully arrange the warm grilled cauliflower wedges over the sauce.

Next, I spoon the sumac onions over the cauliflower, allowing some to fall onto the yogurt for a colorful presentation.

Step 8: Garnish and Serve

I finish the dish with fresh parsley or cilantro, an extra sprinkle of sumac, toasted pine nuts or pistachios, and a drizzle of extra virgin olive oil.

I serve the cauliflower immediately with fresh lemon wedges on the side.

I especially enjoy pairing this dish with warm pita bread, fluffy couscous, or a fresh Mediterranean salad.

Servings and Timing

I find that one large head of cauliflower makes approximately four side-dish servings or two generous vegetarian main-course portions. These are estimated timings for this version of the recipe, and I allow extra cooking time for particularly thick wedges.

Variations

Make It Vegan

I replace the Greek yogurt with a thick, unsweetened plant-based yogurt, such as coconut or soy yogurt. I make sure the yogurt has a neutral flavor so the tahini and lemon remain the dominant flavors.

I find that this simple substitution creates a delicious dairy-free version without sacrificing the creamy texture.

Add a Spicy Kick

When I want extra heat, I add ½ teaspoon of chili flakes or a pinch of cayenne pepper to the cauliflower marinade.

I also enjoy drizzling a little harissa over the finished dish for a bold North African-inspired twist.

Try Roasted Cauliflower Instead

If I don’t have access to a grill, I roast the seasoned cauliflower wedges in a preheated 425°F (220°C) oven for approximately 25–35 minutes, turning carefully halfway through.

I love how roasting produces caramelized edges and tender centers with minimal effort.

Add Pomegranate Seeds

For a fresh and colorful variation, I sprinkle pomegranate seeds over the finished dish.

I especially enjoy the contrast between the sweet, juicy seeds, tangy sumac onions, and creamy tahini yogurt.

Make It Extra Crunchy

I add toasted almonds, pine nuts, pistachios, or crispy chickpeas before serving.

I find that a crunchy topping gives the dish more texture and makes it feel even more satisfying.

Turn It Into a Complete Meal

I serve the grilled cauliflower wedges over cooked quinoa, pearl couscous, or bulgur wheat.

For additional protein, I add roasted chickpeas or lentils. I love how these simple additions transform the recipe into a hearty vegetarian dinner.

Storage/Reheating

Refrigerating

I allow the grilled cauliflower to cool before placing it in an airtight container. I store it in the refrigerator for up to 3–4 days.

I keep the tahini yogurt sauce in a separate sealed container and refrigerate it for up to 3 days.

I also store the sumac onions separately for up to 3 days to maintain their flavor and texture.

Freezing

I can freeze the grilled cauliflower wedges for up to 2 months in a freezer-safe container, although I find that their texture becomes softer after thawing.

I prefer not to freeze the tahini yogurt sauce because the yogurt may separate and become grainy.

For the best results, I prepare the sauce and sumac onions fresh when serving previously frozen cauliflower.

Reheating in the Oven

I preheat my oven to 375°F (190°C) and arrange the cauliflower wedges on a baking sheet.

I reheat them for approximately 10–15 minutes, or until thoroughly heated.

I prefer this method because it helps restore some of the cauliflower’s caramelized texture.

Reheating in the Air Fryer

I place the cauliflower wedges in my air fryer at 350°F (175°C) for approximately 5–7 minutes.

I check them halfway through to prevent the edges from becoming too dark.

Reheating on the Stovetop

I heat a lightly oiled skillet over medium heat and warm the cauliflower wedges for several minutes on each side until heated through.

I always add the cold tahini yogurt sauce and sumac onions after reheating to preserve their fresh flavors.

FAQs

1. How do I keep cauliflower wedges from falling apart on the grill?

I make sure to leave the central core intact when cutting the cauliflower into wedges. The core helps hold the florets together and makes the wedges easier to handle.

I also avoid cutting the wedges too thin and use a wide spatula when turning them. I find that gentle handling is the key to keeping the cauliflower beautifully shaped.

2. Can I prepare grilled cauliflower wedges ahead of time?

Yes! I often prepare the tahini yogurt sauce and sumac onions a day in advance and store them separately in the refrigerator.

I can also cut and season the cauliflower several hours before cooking. However, I prefer grilling the wedges shortly before serving because freshly grilled cauliflower has the best texture and flavor.

3. What does sumac taste like, and can I substitute it?

I love sumac for its bright, tangy, slightly fruity flavor. It adds a refreshing citrus-like taste to the onions without making them overly acidic.

If I don’t have sumac, I use a little extra lemon juice and a small amount of lemon zest. Although the flavor isn’t exactly the same, I find that this combination provides a similar refreshing acidity.

4. Can I make this recipe without an outdoor grill?

Absolutely! I often use a stovetop grill pan or roast the cauliflower in the oven when outdoor grilling isn’t convenient.

For oven roasting, I arrange the seasoned wedges on a baking sheet and cook them at 425°F (220°C) for approximately 25–35 minutes, depending on their thickness.

I turn them halfway through cooking to encourage even browning.

5. What can I serve with grilled cauliflower wedges and tahini yogurt?

I enjoy serving these cauliflower wedges alongside warm pita bread, hummus, tabbouleh, couscous, or a fresh cucumber and tomato salad.

When I want a more filling meal, I pair them with roasted chickpeas, lentils, grilled chicken, or baked fish.

I especially love including this recipe in a Mediterranean mezze spread because the creamy tahini yogurt and tangy onions complement so many other dishes.

Conclusion

Grilled Cauliflower Wedges with Tahini Yogurt & Sumac Onions is a delicious example of how simple vegetables can become the centerpiece of a memorable meal. I love the balance of smoky, caramelized cauliflower, rich and creamy tahini yogurt, and bright
