I enjoy roasting vegetables, and cauliflower is one of my favorite dishes. Easy to work with and foolproof, there are so many seasonings.

An open canvas.

Our local market had beautiful cauliflower assortments and decided to change things a bit, meaning straying from the usual white and cooking with an orange one this time.

It’s the same flavor, just a different color. I guess it’s more festive for me.

Roasted Cauliflower with Lime Dressing

Ingredients needed to make your roasted cauliflower recipe

Large cauliflower head – No bruising on the main part of the head and no mildew on the stem. You can have fun here. A white cauliflower head for the spring and summer, and why not an orange one for the fall season, adding a bit of fun to your table? I use both, and there is no difference in taste or flavor.

Limes – are used to bake the roasted cauliflower in the oven and create the lime dressing.

Olive oil – to roast your cauliflower in the oven.

Garlic clove – with the lime, the garlic flavor is uplifted with this recipe.

Mustard – marries well with teh mustard and creates with the mayonnaise a creamy dressing.

Mayonnaise – used for the lime dressing, tames the lime’s flavor without removing the acidity’s essence.

Salt and pepper – the seasoning needed for this recipe.

Fresh tarragon – is optional, but if you have some on hand, it adds a nice flavor.

Mixing bowls – used to mix your cauliflower and one to prepare the sauce for the roasted cauliflower

Cookie sheet – to bake the cauliflower

Chef’s knife – to cut away at the cauliflower florets from the stalk.

Step by step on how to Roast Cauliflower

The success of this super easy dish is in a hot oven. At 400 degrees F. creating a beautiful golden brown and crispy florets.

I do use the core and greens. Slice the core into rounds and roast them alongside the florets. You can always use them in soup later by freezing them.

Start with the hard of cauliflower:

  • Wash your head of cauliflower and dry it thoroughly. This step will help accelerate the crisping process.
  • I like to take each floret and either quarter them or halve them. Whichever direction you choose to cut them, ensure they are all the same size.

You can season them on a cookie sheet by drizzling olive oil over them, or if you prefer, in a bowl. 

  • I add lime or lemon juice for two reasons. Once, to keep them moist. The second is that the lemon and/or lime will remove some of the smell appropriate to the cauliflower. Smell that is not particularly liked.

Once ready, place them in the hot oven:

  • Leave space in between the florets and do not overcrowd them or they will not brown and crisp around the edges.
  • Roast in the preheated oven and turn over once.

Meanwhile, prepare the lime salad dressing:

  • Grate the garlic in a bowl and add the lime, mustard, mayonnaise, and olive oil. Stir well and taste. Adjust seasoning to your liking by adding more olive oil if need be.
  • Your dressing can be stored in the refrigerator for up to a week.

Assembling your dish:

  • Once your florets are golden brown and perfectly crispy, add them to your bowl with the salad dressing. Add fresh tarragon, optional, and serve.

Lime Dressing

You can enjoy this wonderfully tasty lime dressing with roasted vegetables: Carrots, broccoli, Brussels Sprouts, fennel, and tomatoes.

It will store well in the refrigerator for up to a week.

Pro Tips

  • Garlic: To enjoy the pure essence of the garlic minus the bitter chunks of chopped garlic, which to me are not the most pleasant to bite into, grating it is my solution. The grating brings out all the natural oils and enhances the olive oil and lime to a new taste level.
  • Beware, as it may be a bit strong. Adjust to your liking.

Roasted Cauliflower Variations

  • Spice things up with cumin, coriander, turmeric, capers, and pine nuts.
  • Some lemon zest with fresh tarragon, as I have it here, which you can substitute with fresh parsley, fresh thyme, or minced fresh rosemary.
  • Freshly grated Parmesan cheese is sprinkled over the florets for the last 5 minutes of baking or until the cheese is melted.

Storing your oven-roasted cauliflower

This recipe stores well in an airtight container in the fridge for several days.

Please bring it back to room temperature and enjoy.
