How to select the perfect cauliflower
When selecting your head of cauliflower, avoid crumbly florets, brown spots, and dull color. The outer leaves should look fresh and beautiful, vibrant green.
If you buy them already pre-cut, select pieces with no discoloration.

Ingredients needed to make this excellent oven-roasted cauliflower with lemon dressing
This is a short introduction. The ingredient list is also brief. It includes essential items that you may already have in your pantry. Please read the recipe for complete instructions.
Cauliflower – nicely round, tight florets and a beautiful cream color with no bruising
Garlic – you can mince it or even grate it if you wish. Gives that uplifting flavor to your recipe
Lemon – with the sweetness of the cauliflower, it adds a layer of acidity.
Olive oil – used in the baking process as well as for dressing
Salt – the only seasoning you will need, and just a splash.

Roasting tips and step-by-step instructions on how to make this roasted cauliflower recipe
For all my recipes, please gather all the ingredients before you start cooking or baking, and I will guide you every step of the way.
- Preheat the oven to 400F
- Start by removing the florets from the cauliflower’s trunk.
- Split large florets into bite-sized pieces for easier eating.
- Toss the florets with love oil and place them on a rimmed baking sheet.
- Please place them in the preheated oven and bake until browned and crisp.
Meanwhile, prepare the vinaigrette by mincing or grating the garlic, whisking it with lemon juice, a splash of olive oil, and a dash of salt.
- Once the cauliflower florets are done, mix them with the vinaigrette and serve.
This roasted cauliflower recipe can be enjoyed warm or at room temperature.

The garlic in the lemon dressing is a great addition to it. However, it can be omitted if you wish.
Giangi’s Pro Tip
- Mincing or grating the garlic? I prefer grating because, to me, the natural oil and flavor of the garlic are intensified and mixed well with the lemon and oil, and I do not bite into chunks of garlic.
- Mincing is terrific, too, if you prefer a more pungent bite of garlic.
Variations and Substitutions
- Add a few grinds of black pepper to the finished dish to add a kick of heat.
- With all the selection of cauliflower at the market, you can make this recipe with orange or purple cauliflower.
- Instead of cutting it into florets, you can slice the cauliflower into steaks and proceed with the recipe described below. Check for doneness, as every oven bakes differently.
Make Ahead, Storing and Reheating
Meal Prep: you can pre-chop your cauliflower up to two days before using it, cover and refrigerate. Add seasoning before roasting.
Refrigerate: once cooled to room temperature, store in an airtight glass container for up two days.
Reheating: It is not necessary to bring it back to room temperature before you enjoy it again. However, if you wish to eat it warm, you can reheat it on the stovetop or oven until heated.
Frequently Asked Questions
Is cauliflower a winter vegetable?
Yes, it is a very sturdy winter vegetable. Cauliflower loves the cold weather and is rich in Vitamin C.
What part of the cauliflower is not edible?
Every part of the cauliflower is edible, not only the florets but also the trunk. I recommend peeling the outer part before cooking it, as it will be tough.
Is it OK to eat cauliflower every day?
Everybody tolerates food differently, but too much cauliflower is known to cause some G.I. distress, such as gas and bloating. It would be best to drink plenty of water to help it move through your system.

Such a simple recipe. My husband loves cauliflower and he really enjoyed this (plus he is trying to eat lighter so this was perfect). I made half with your recipe and the other half with buffalo sauce for my son and he gobbled it up.

The buffalo sauce sounds fun! I am happy your husband enjoyed it.
Thank you for making my recipe and sharing your feedback.

Even the kids loved this! I am always looking for ways to prepare veggie sides that they will eat. I will be making this again for sure!

Kristina
It’s amazing how a few simple and fresh ingredients combine to make such a delicious recipe like they do here. This cauliflower turned out perfectly seasoned and roasted and it made a great side for our grilled dinner this weekend. I like using roasted garlic as well, for a little extra garlicky flavor.

Anything with garlic always tastes yummy. Thank you for the suggestion.
Enjoy!
