What makes Roasted Cauliflower with Garlic so good?
I love the way roasting at a high temperature brings out the flavor of vegetables, and roasted cauliflower gets a slightly nutty flavor that you don’t get from cauliflower that’s cooked in other ways. And in this recipe the flavor of the roasted garlic is such a bonus! Don’t be afraid to roast the cauliflower until it’s starting to get slightly browned on the edges; that will make the flavor even better!

Can I make roasted cauliflower with frozen cauliflower?
I can’t imagine making this with frozen cauliflower. Since it’s already partially cooked, I don’t think the garlic will get done in the time it takes to cook the cauliflower. And you’d have to thaw it first so I am guessing it might be soggy.
If you do try it, I’d love to hear how it works.
Cindy I love that idea of topping cauliflower with all those other flavorful things!
Mmmm! I like to use roasted cauliflower as a substitute for potatoes. I have never tried it with fresh garlic! Must try! Have you ever had the hashbrowns at WaffleHouse, where they add all kinds of toppings to them? My favorite was hashbrowns with onions, bell pepper, tomatoes and ham. Now I do the same with the roasted cauliflower. I add the onions and peppers at the beginning of the roasting time, and add tomato and ham (or bacon bits!) at about the halfway point. The rest of the family adds cheese, too, but I can't eat dairy. I love garlic, so I am gonna hafta try this version!
-M, have not tried pureeing it, but I would imagine it would taste wonderful. Let us know if you try it.
Hey Kalyn! Have you ever pureed the roasted cauliflower? I’d like to serve it with meatloaf, so I think a mashed/pureed version would be better. Thanks!
My favorite variation: to toss in some capers, chopped olives and a spritz of lemon juice at the end!
This caulflower is amazing. I have made it for about 6 months now and everyone eats it – from my husband all the way down to my toddler . It also is a hit at dinner parties.
Hey I’m closely following your posts. They are really interesting…..keep up the good work!!!
Biggles, hmmmm. Adding the flavor after. Have to give that some thought.
Alanna, amazing that this was your first post.
Cookiecrumb, my brother found the wonderful beans. He’s amazing. I’m thinking the darker the cauliflower (up to a point) the more toasty it will taste. Let me know if you try the longer time.
Aria, it was fabulous, if I do say so. (Well of course I can say so, it’s Alanna’s recipe!)
mmmmyes, roasted cauliflour is so good!!!
Hey, cool beans! (Your banner.)
I think the color of your roasted cauliflower looks fine, but if Alanna’s pushing for an even darker color, maybe I’ll just have to get brave and try.
It’s so funny to see the unassuming “Day One” of A Veggie Venture up in lights at Kalyn’s Kitchen … that’s something like 450 vegetables ago and low-carb without even trying! I haven’t made a tray yet this year, but will check timing for the browning aka caramelization. Thanks for making this! ; – )
Hey Kalyn,
I’m as surprised as you. Cauliflower is like meat. It takes intense heat while cooking and can hold a staggering array of spices & herbs.
After playing with it for the last year, I get the best results by adding flavors afterwards. Except for the curry version, that was good too!

Bill, I like cauliflower most any way. One of my faves is Cauliflower Fried in Butter, an old Frugal Gourmet recipe.
Kitarra, I would have kept the garlic whole, but I didn’t have any big garlic cloves.
Sher, never grown cauliflower. I bet it’s wonderful.
Scott, I think veggies are great.
Christine, your combination sounds great.
W_P, me too!
Biggles, who would imagined you’d become vegetarian for a meal?
Hey,
I recently did a post about roasting cauliflower and realized there’s very little you can’t do to make it a wonderful dish or an entire meal. I do mine at 450 for 30 minutes. And this last time just did onions, mushrooms and the cauliflower. It was so good it was all I had for dinner. That’s saying something coming from me. No meat?

This cauliflower dish lokks absolutely yummy… I love cauliflower!
Yum! Great recipe. I love roasted cauliflower and I’d already decided to roast it tonight along with broccoli, leeks, a few carrots and garlic to accompany lamb chops. Post coming soon…
Lovely. Aren’t vegetables underused in the kitchen these days? The always have to “accompany” something, but this is delicious on it’s own.
We’re great fans of cauliflower in my house–and I just planted some. So, this will be on my table for sure!
This is the BEST way to make cauliflower! Though I keep my garlic whole. It provides a subtle garlic flavor and you can eat the whole soft cloves at the end. I also make it with different kinds of oils. My favorite is hazelnut oil right now but I bet flax seed woul be good too!
This is about the only way I’ll eat cauliflower these days 😉
