How to Roast Cauliflower

Oven roasted Cauliflower is really easy to make. It’s one of those simple side dishes you can just throw in the oven while you’re focusing on cooking your main dish. Let it get crispy and flavorful without worrying too much about it, and then it’s ready to go! I like to roast cauliflower with chunks of garlic, onion, and lots of herbs so it can soak up all the flavors.

How to Roast Cauliflower:

  1. Preheat oven to 425°F & cover baking sheet with aluminum foil
  2. Place cauliflower florets on baking sheet along with garlic & onion
  3. Drizzle olive oil over everything, sprinkle with red pepper, thyme, salt, & black pepper
  4. Roast for 35-45 minutes

You can use different spices, herbs, and seasonings if you prefer, but this is the basic process for making roasted cauliflower to follow every time. It comes out nice and crispy and full of flavor.

Homemade Chimichurri Sauce

The homemade chimichurri sauce is my favorite part of this recipe! Roasted cauliflower is SO GOOD, and the chimichurri really brings it to the next level. I created my own chimichurri recipe based on the traditional Argentinian sauce. While it’s generally used on grilled meats as a marinade, I love the garlicy flavor so much that I wanted to use it on other stuff too! I think it is just perfect on this roasted cauliflower recipe and really makes an amazing cauliflower side dish.

How long do you roast cauliflower at 425°?

To get it nice and crispy, roast cauliflower at 425°F for about 35-45 minutes.

What are the benefits of eating cauliflower?

Cauliflower is really great vegetable with lots of health benefits. It’s considered to be a “cancer-fighting” vegetable; it’s anti-inflammatory and rich in anti-oxidants; and it’s filled with tons of important nutrients like vitamin K, riboflavin, fiber, folate, potassium, and more.

How long can you keep cauliflower in the refrigerator?

A fresh head of cauliflower (uncooked) should usually last in the refrigerator for up to 2 weeks. It tends to hold up better than a lot of other produce.

This roasted cauliflower recipe can be stored in the refrigerator after cooking if you have leftovers. Store the cauliflower and the sauce separately. The cauliflower should keep for up to 1 week, while the sauce can last for 2 or 3 weeks.
