Easy Roasted Cauliflower is a delicious and easy side that the whole family will love. Crisp white cauliflower is tossed in with a flavorful olive oil mixture then roasted to golden perfection!

Making great side dishes doesn’t have to take a lot of effort! This easy side dish is the perfect accompaniment for Crispy Baked Parmesan Chicken or even Chicken Stroganoff!

An Easy Cauliflower Side Dish

I always struggle to find a side dish that is healthy, fits nicely with my side, and doesn’t take too much time or effort. I’ve found that roasting vegetables (like my favorite Easy Baked Zucchini) is the perfect side with very little effort and tons of flavor! This roasted cauliflower is simple, super quick, and my husband and daughter call it ‘the star of the show’. What could be better?

While I’ve made Whole Roasted Cauliflower, I find that it takes a bit longer so on a weeknight I prefer to chop it up and roast it.  Roasted Parmesan Broccoli is so good, feel free to add broccoli into this dish too!

Most of the roasted cauliflower recipes I’ve seen have parmesan cheese however this dish is both simple and light (although if you like feel free to add a sprinkle of parm to this recipe too)!

While this is one of my favorite flavor combinations, you can definitely swap up the seasonings or even a few chili flakes to this roasted cauliflower to kick it up a notch. Experiment a little and find a flavor combo that makes your taste buds happy!

This easy side is low carb, keto friendly and a totally guilt free option everyone loves. If you have a main dish in mind that is also low carb (like a perfectly cooked Steak), you are well on your way to a perfect dinner!

How To Roast Cauliflower

It is so so SO simple to make roasted cauliflower. I make baked cauliflower too but roasted cauliflower should be cooked at a higher temperature to really encourage the browning.

  1. Break the cauliflower into bite sized pieces as uniform as possible so they all roast at relatively the same speed. Make sure you dry the cauliflower as water will make it steam instead of roast.
  2. Combine olive oil and seasonings. Toss your cauliflower and oil mixture together until everything is coated nicely.
  3. Roast at a high heat (425-450°F) until golden.

How Long To Roast Cauliflower

The real key to perfect roasted cauliflower is a high oven temperature.  With a higher temperature, you’ll get the beautiful brown caramelization without overcooking the cauliflower. Lower temperatures will cause the cauliflower to cook too much before it browns!

Roast your cauliflower in a 425-450°F oven for 10-15 minutes or until they are fork tender. I find that throwing them on the bottom rack while I have my main dish roasting is the perfect time saver. I like to flip my roasted cauliflower half way through cooking to ensure it roasts evenly!  Serve it alongside a main dish like these barbecue ribs made in the oven, or enjoy it as a healthy and low carb snack option!

  1. Love your recipies they are my go to! Thank you for the work you put in. Not sure if you’ve tried roasting cauliflower leaves and thinly sliced stalked too, but they are delicious. They sometimes take longer to cook than the rest of the florets and they are my fav! Especially when roasted or added to curries etc
