Roasted cauliflower Greek salad combines golden, crisp cauliflower with halved cherry tomatoes, diced cucumber, red onion, kalamata olives and crumbled feta, tossed in a lemon-oregano vinaigrette. Serve warm or room temperature for easy weeknight meals and make-ahead lunches.
Why this roasted cauliflower Greek salad works
This roasted cauliflower Greek salad balances texture and brightness so every bite is interesting: the cauliflower gives warm caramelized edges and a satisfying chew while the tomatoes, cucumber and onion keep things fresh. The lemon-oregano vinaigrette has a 3:1 oil to acid ratio so it clings without overwhelming the vegetables.
We like this as a vegetarian main, an easy side, or a meal-prep bowl. Add chickpeas, grilled chicken or halloumi to boost protein. For more Mediterranean mains that pair well, try our feta chicken thighs with artichoke hearts or a comforting Greek-style chicken fricassee.
Ingredients — what you need
Below are quantities for 4 servings. We list imperial and metric measurements so you can cook confidently. Use cherry tomatoes to limit extra juice, and pat cucumber and tomatoes dry if you plan to dress this ahead.
- Vegetables and add-ins: 1 medium head cauliflower (about 1-1.2 lb / 450-550 g), 2 cups cherry tomatoes halved (300 g), 1 medium English cucumber diced (200 g), 1/4 red onion thinly sliced, 1/3 cup pitted kalamata olives (50 g), 4 oz / 115 g feta, crumbled.
- Dressing: 3 tbsp / 45 ml extra-virgin olive oil, 1 tbsp / 15 ml fresh lemon juice + 1 tbsp / 15 ml red wine vinegar (or use 2 tbsp / 30 ml lemon juice total), 1 small garlic clove minced, 1 tsp dried oregano or 1 tbsp chopped fresh oregano, 1/2 tsp salt, 1/4 tsp black pepper.
- Optional proteins and swaps: 1 can chickpeas (15 oz / 425 g) drained to keep it light, grilled chicken, halloumi, or vegan feta and tahini in place of dairy.
Equipment
You do not need fancy gear. Use a rimmed sheet pan for roasting so juices do not spill and the cauliflower can spread in a single layer. If you prefer, roast in an air fryer basket. A large mixing bowl, a small jar for dressing, and an accurate scale or measuring spoons make the job easier.
We recommend a heavy rimmed sheet, parchment or a lightly oiled pan, and a spatula for turning. For air fryer instructions see the roasting section below.
Step-by-step: how to roast cauliflower perfectly
Roasting cauliflower well is the heart of this salad. Below are precise, repeatable steps for conventional ovens, convection ovens and air fryers so your florets brown and crisp instead of steaming.
How to prep and cut the cauliflower
Trim the stem and separate the head into even florets about 1-1.5 inches / 2.5-3.5 cm across. Consistent size ensures even browning. Larger chunks need more time and will stay softer in the center.
Seasoning and oil
Toss florets with about 1-2 tbsp / 15-30 ml olive oil per 1 lb / 450 g cauliflower, 1/2 tsp kosher salt and a pinch of black pepper. You want a light sheen, not pooling oil. Add 1/2 tsp smoked paprika or cumin if you want a savory edge.
Oven temps, timing and flipping
For a conventional oven use 425°F / 220°C and roast for 25-30 minutes, tossing once at about 12-15 minutes. For convection ovens lower the temp to 400°F / 205°C and roast 20-25 minutes. In an air fryer roast at 400°F / 200°C for 12-18 minutes, shaking halfway.
Visual cues: look for golden edges and deep caramel color on several florets, with some darker brown spots on tips. If the cauliflower is pale and soft, increase heat and give more time; if it is blackened, lower the temperature next time.
Tips for extra-crisp cauliflower
Spread florets in a single layer with at least 1-2 cm space between them so hot air circulates. Avoid overcrowding or the florets will steam. Use a preheated sheet for faster caramelization or roast on a cold sheet to avoid sticking; both work but we prefer a hot sheet when time is short. For reliably crisp edges try the baking powder trick: mix 1/2 tsp baking powder with the oil and salt to encourage browning, not flavor change.
Make the lemon-oregano Greek vinaigrette
This is a simple, stable vinaigrette that clings to roasted cauliflower and fresh veg. Use a 3:1 oil to acid ratio for balance and an emulsifier like a small spoon of dijon or vigorous shaking.
Combine 3 tbsp / 45 ml extra-virgin olive oil, 1 tbsp / 15 ml lemon juice and 1 tbsp / 15 ml red wine vinegar, 1 small minced garlic clove, 1 tsp dried oregano (or 1 tbsp chopped fresh), 1/2 tsp salt and 1/4 tsp black pepper in a jar. Shake until emulsified, or whisk in a bowl until glossy. Taste and adjust salt. If the dressing tastes flat, add another teaspoon lemon juice or a pinch more salt; acid brightens flavors.
Assemble the salad and timing
To avoid a soggy salad, timing matters: dress components just before serving, and add delicate ingredients like feta and herbs last. Roasted cauliflower can be warm or room temperature when you toss the salad.
Assembly order: in a large bowl combine halved cherry tomatoes, diced cucumber, sliced red onion and olives, then add roasted cauliflower and pour about 3-4 tbsp dressing over the top for the whole salad. Toss gently, then sprinkle 4 oz / 115 g crumbled feta and torn herbs like parsley or mint just before serving.
Pro tip:
For meal prep keep the salad undressed in the fridge up to 24 hours; store dressing separately for 4-5 days. If you must dress ahead, reserve the feta and herbs until serving and use only half the dressing so ingredients do not get soggy.
Variations, make-ahead, storage, troubleshooting and nutrition
Variations and add-ins: Add a can of rinsed chickpeas (15 oz / 425 g) for fiber and heft, or top with grilled chicken or halloumi for extra protein. For a vegan version swap feta for firm tofu cubes or vegan feta and replace the dressing with a tahini-lemon blend.
Make-ahead and storage: Store roasted cauliflower in an airtight container for 3-4 days in the fridge. Keep the dressing separate for 4-5 days. Assembled and dressed salad is best the same day, but undressed you can store it up to 24 hours.
Troubleshooting common issues: If your cauliflower turns soggy it is usually from overcrowding the pan, cutting florets too small, or using too much oil. If tomatoes or cucumber make the salad watery, halve cherry tomatoes and pat diced cucumber and tomatoes dry on a kitchen towel. I learned this the hard way: I used supermarket tomatoes that were ripe and juicy, and the salad watered down quickly. Now I halve cherry tomatoes and blot them dry before tossing, and that simple step saved the texture every time.
Nutrition estimate per serving: about 270 kcal, 12 g protein (without added chicken), 18 g fat, and 18 g carbohydrates. Values vary with add-ins like chickpeas or chicken. For a fuller protein boost add grilled chicken or a drained can of chickpeas.
Pairings: Serve this salad with simply grilled lamb or pan-seared fish, or pair with Mediterranean sides. For a lighter weeknight dinner add a warm grain like farro or quinoa to make it a bowl.

1/3 cup pitted kalamata olives (50 g)
4 oz / 115 g feta, crumbled

Directions
- Preheat the oven to 425°F / 220°C for a conventional oven, or 400°F / 205°C for convection; if using an air fryer set it to 400°F / 200°C.
- Cut the cauliflower into even 1-1.5 inch / 2.5-3.5 cm florets and toss in a bowl with 1-2 tbsp / 15-30 ml olive oil per 1 lb / 450 g, 1/2 tsp salt and a pinch of pepper until lightly coated.
- Arrange florets in a single layer on a rimmed sheet with 1-2 cm gaps and roast in the conventional oven at 425°F / 220°C for 25-30 minutes, tossing once at about 12-15 minutes, until edges are golden and caramelized.
- If using a convection oven roast at 400°F / 205°C for 20-25 minutes; in an air fryer cook at 400°F / 200°C for 12-18 minutes, shaking the basket halfway through.
- Meanwhile, halve cherry tomatoes, dice cucumber and thinly slice red onion and place in a large bowl; pat tomatoes and cucumber dry if you plan to store or dress ahead to avoid extra water.
- Make the dressing by combining 3 tbsp / 45 ml olive oil, 1 tbsp / 15 ml lemon juice and 1 tbsp / 15 ml red wine vinegar, 1 minced garlic clove, 1 tsp dried oregano, 1/2 tsp salt and 1/4 tsp pepper in a jar and shaking until emulsified.
- When the cauliflower is done, add warm or room temperature florets to the bowl with the fresh vegetables, pour about 3-4 tbsp dressing over the salad, toss gently, then finish with 4 oz / 115 g crumbled feta and chopped herbs before serving.
Notes
- Tip 1: Pat tomatoes and cucumber dry on a towel to prevent a watery salad.
Tip 2: Spread florets with space between them so they brown instead of steam.
Tip 3: Store dressing separately for 4-5 days and roasted cauliflower for 3-4 days in the fridge.
