I don’t know about you, but I’m tired of seeing cauliflower forced into pretending to be everything BUT cauliflower. Sure, it can masquerade as rice, pizza dough, potatoes, and whatever else you’re trying to avoid.

But cauliflower, as cauliflower, is an incredible vegetable. And roasting it until it has caramelized brown edges is the perfect way to bring out its best.

This is a dish we made in culinary school, and I was shocked at how much incredible flavor you could get with just these simple techniques and ingredients. It’s a must try!

This recipe takes perfectly roasted cauliflower and tosses it in gremolata, a bright, fresh mixture of parsley, lemon zest, and garlic. With just a handful of ingredients, this cauliflower proves how much flavor you can get from a well-roasted vegetable.

Ingredients

Cauliflower: This recipe calls for 12 oz. cauliflower florets, or about 1 head. While I love this recipe enough to double it, I’d advise only doing so if you have a sheet pan large enough to still give the florets plenty of breathing room.
Olive oil, salt, and pepper: This flavors the cauliflower during its initial roasting. The olive oil helps caramelize the edges of the cauliflower.
Fresh parsley, lemon zest, and garlic: This makes up the classic gremolata we will toss the cauliflower in. You can adjust exact quantities to taste, but I’d advise against using too much garlic: the cauliflower cooks down quite a bit and raw minced garlic can easily become overpowering.
Butter, salt, and pepper: Tossing the roasted cauliflower in butter adds extra flavor and helps the gremolata to stick. A final addition of salt and pepper to taste really helps the dish shine!

How to make roasted cauliflower with gremolata

Roasting the cauliflower at a high enough temperature with plenty of breathing room on the pan is the key to perfectly caramelized edges.

Cut and roast the cauliflower. If you are getting pre-cut florets, these usually need to be cut into smaller, bite-sized pieces so they will cook evenly and have plenty of crispy edges. Toss in olive oil, salt, and pepper, and roast at 400 degrees F for 20-30 minutes. 25-30 was the sweet spot for me to get those lovely edges.

Make the gremolata. Finely chop fresh parsley, zest a lemon, and mince a small clove of garlic. Mix together in a small bowl.

Toss together. Toss roasted cauliflower in butter while it's still hot, until butter is melted. Add gremolata, toss again, and add salt and pepper to taste.

Enjoy! Serve with baked chicken thighs, lemon soy salmon, or your favorite protein main.

Tips & Tricks

Use a large sheet pan: Having plenty of breathing room on the pan for your cauliflower is key to getting those crispy, caramelized edges. Without adequate space around each floret, the cauliflower will steam and become mushy before the edges brown.
Fully preheat your oven: Ovens can be misleading; they often use a timer instead of a thermometer to tell you when your oven is preheated. If you don't have a standalone oven thermometer you can cross check (available for under $10) give your oven an extra 15 minutes to preheat for best results.
Use lightly dried parsley as a shortcut: Lightly dried herbs (from Gourmet Garden) are a staple in my refrigerator — they're flavorful, fresh, and convenient. You can use a couple tablespoons of their parsley if you don't want to buy an entire bunch of parsley or spend time chopping your own.
