Here are the ingredients you’ll need to make roasted cauliflower:
- Fresh cauliflower. Cut the cauliflower into small florets, and rinse well. Make sure to dry the florets well so that the oil and seasonings will coat them. Using a salad spinner is a great idea!
- Olive Oil. You’ll need a decent amount of oil to roast the cauliflower. I use 3-4 tablespoons. It may seem like a lot, but it really helps get the cauliflower brown and crispy.
- Salt and Pepper.
Flavor Ideas for Roasted Cauliflower
For this basic recipe, I call for just salt, and pepper as the seasonings. But, cauliflower has such a neutral flavor — it’s perfect for seasoning with your favorite herbs and spices. I encourage you to add more flavors and seasonings to suit your taste. Here are some ideas.
- Add a few cloves of minced garlic, or 1/2 teaspoon of garlic powder to the cauliflower before roasting
- Add up to a tsp of dried herbs, or an all-purpose herb blend.
- Add up to a tbsp of taco seasoning to the cauliflower before roasting. Add it to the bowl when you’re tossing the florets in the olive oil. (This is so good!)
- Add up to 1/2 cup of grated Parmesan cheese to the cauliflower, about halfway through the cooking time. This way it will melt and brown, but not burn in the high heat of the oven.
How to Make Oven Roasted Cauliflower
Making oven-roasted cauliflower is a very simple recipe. After a few minutes of prep, the oven takes care of the rest of the work for you.
To start, wash and dry the cauliflower thoroughly. Cut the cauliflower into small florets. Try to keep the size of the pieces relatively uniform so they will cook evenly.
Then, in a large mixing bowl, toss the florets with olive oil, garlic, salt and pepper to taste. Now is the time to add any additional seasonings, like Balsamic vinegar, red pepper flakes, herbs, or other seasonings.
Next, place the cauliflower on a large rimmed baking sheet. Spread it out in a single layer, being careful not to overcrowd the pan.
Finally, roast the cauliflower in a hot oven for about 20 minutes, or until it is tender and caramelized. That’s it!
Tips for the Best Roasted Cauliflower
These tips apply to this cauliflower recipe, but also for other roasted vegetable dishes like roasted broccoli or roasted brussels sprouts.
- Make sure that the cauliflower florets are dry after rinsing them. You can use a salad spinner or pat them down with paper towels.
- Be generous with the olive oil. Toss the florets will to make sure that they are coated in a thin layer of oil. The oil will make sure that the cauliflower cooks and browns well.
- Don’t overcrowd the pan. It’s important to spread the cauliflower out into a single layer on a large pan. You can use two pans if you don’t have one pan that is large enough to hold all of it at once. If you crowd the pan, the cauliflower will end up steaming and you won’t get brown and crispy edges.
- Use a high enough oven temperature. 425F is the sweet spot in my oven. You may want to buy an oven thermometer if you aren’t sure if your oven is accurate.
- Shake the pan, or use a spatula to toss the cauliflower about halfway through the cooking time for even cooking.
