I took Wednesday off posting and now it seems like I haven’t posted for 2 years. I was so, so, so tired that my body was telling me to go to sleep at 8:30. So I decided to listen (for once) and hit the hay instead of working.

And then I didn’t fall asleep until 12:30.

I hate it when that happens. So here I am, writing the post that I had planned for Wednesday. My son, who is now 10 months old (I KNOWWWW—HOW DID THAT HAPPEN?!?) likes to get up at 5AM Guess what? Today he slept until 7:45. I practically had a heart attack. I actually got some work done before he got up (not this post though, of course…). I enjoyed a cup of coffee before I nursed him. Everyone please say your prayers that it wasn’t a fluke thing. This could be life changing. Maybe I’ll even start working out again.


So yeah…ummm…about that whole not working out thing. Turns out you gotta eat pretty healthy food if you don’t want to work out but don’t want to get fat. I’ve been roasting vegetables like it is my job (wait…I guess it kind of is my job?) and we LOVE them this way. Cauliflower is no exception. Roasted broccoli is amazing, roasted carrots are amazing, mushrooms, squash, etc. You get the point. It brings so much flavor and texture out of the vegetable. It really is the best way to eat it.  And it is unbelievably easy, which is always a bonus.

Once you learn the basics of how to roast cauliflower, you’ll find yourself doing it constantly! Once you learn this method, make sure to try my parmesan roasted cauliflower, too.

Tip: The recipe is written for 425°F but if you need to roast it at a lower temperature like 400°F or even 350°F, you may do so. It won’t cook as quickly and it may not get quiiiiiite as crispy, but it will work if you have something else in the oven that you need to cook at a specific temperature.

I’ve also used roasted cauliflower in other recipes, too. Even though the cauliflower is blended into other ingredients, roasting it first gives it amazing depth of flavor and adds another layer for you to enjoy. Everyone will want to know your secret and how to roast cauliflower! Try this cauliflower cheddar dip — it’s a healthier alternative to heavy all-cheddar dips. Similarly, this roasted cauliflower and cheddar soup tastes unbelievably rich but it actually won’t break your calorie count for the day.

How to Roast Cauliflower in 3 simple steps:

  1. Wash cauliflower and cut into small florets. The smaller they are, the crispier they’ll get and the quicker they’ll cook.
  2. Toss with olive oil, salt and pepper.
  3. Spread on a baking sheet (give them as much space as possible!) and roast at 425°F until crispy and golden brown!

As always, keep reading for directions and a printable recipe!

  • 1 large bunch of cauliflower (about 4 cups)
  • 2 tablespoons olive oil
  • salt and pepper to taste





  1. Preheat oven 425°F.
  2. Wash cauliflower and dry very thoroughly. (Don’t skip drying — it’s important. You can even use a salad spinner if you have one, or just shake, shake, shake all the water out and then pat dry with a towel.)
  3. Cut into medium-sized spears and coat well with olive oil. Spread onto rimmed baking sheet and sprinkle with salt and pepper.
  4. Bake for 10 minutes, flip each piece over, and bake for 10 more minutes.
  5. Serve immediately.

Note: The more dry the cauliflower is, the better this recipe will turn out.

  1. Is this not the best snack or what? I LOVE cauliflower cooked this way. Can’t wait to see you in a couple weeks, girl!

  2. Thanks for this, Rach. I’m not a veggie roaster at all, so wasn’t sure what temp to put the oven on. :) I’m Rachael from Simply Fresh Cooking, btw! I finally got my health back after being bed bound for most of 2013 and I’m doing fantastic now! My diet has DRASTICALLY changed – that’s how I managed to get myself better! ;) I hope you’re well! The blog is looking great. xo

  7. Roasted cauliflower (and broccoli) are two of my all time favorite veggies!! These look so crunchy and perfect!! Now I have to go to the store… :)

  8. Why have I not tried roasting cauliflower?!

  9. Omg. Want to hear something funny? I’ve been roasting my broccoli in the oven ever since that post of yours. So yesterday (I swear) I bought cauliflower, thinking I would do the same thing. And now here you are. With cauliflower. Isn’t that the most hilaaarious thing ever??

  10. HA I cant believe you psted this! I am working on a roasted cauliflower soup right now! I might just need to tag you in my post ;) Looks yum Rachel.

  11. Best thing EVER when your kids start sleeping later! I hope it is a new trend for you-5am is way too early! I love roasted cauliflower too-yum!

  12. I love roasting veggies. When I do cauliflower, I add curry powder. I think broccoli is my favorite.

  13. Could you use frozen cauliflower thawed and dried?

    • It might be hard to get it dry enough (maybe try a salad spinner?) and frozen cauliflower is typically already blanched (right?) so the cooking time might be less. The result wouldn’t be quite the same, but it’s worth a try!

  14. easy-peasy
