⭐ Tips
Here are a couple of tips for baking this healthy side dish:
✔️ Arrange the cauliflower florets in a single layer on the baking sheet.
✔️ Roasting at a high temperature will ensure the cauliflower roasts instead of steams and gets mushy. Be sure to allow your oven to preheat.
🍲 Storage
To Store: Store leftover roasted cauliflower in an airtight container in the fridge for 3-4 days. (These are my favorite airtight containers.)
You can also use leftovers to make cauliflower rice or cauliflower grits.
To Reheat: Microwave individual portions in 30 second intervals until heated throughout.
Serving Suggestions
- Roasted cauliflower is the perfect side dish for so many meals like grilled lemon pepper chicken, oven roasted pork tenderloin, and broiled NY strip steak.
- You could also add a little bit of basil salt just before serving.
- Roasted caulifower is also pretty amazing served with our Greek yogurt veggie dip.
- Serve with one of our delicious compound butter recipes like garlic basil butter or our cowboy butter dipping sauce.
📖 Variations
The first time you try any new recipe we recommend that you make it just as it is written on the recipe card since that is how the recipe has been tested. However, the next time you make our recipe, you might want to try one of these ideas, like substituting avocado oil or even sesame oil in place of the extra virgin olive oil.
You can roast frozen cauliflower with frozen broccoli or frozen brussel sprouts, too!
I love the versatility of this caulifower recipe! Play with the seasonings until you find your favorite combination. Instead of garlic powder and onion powder, try one of our many seasoning blends instead. Roasted cauliflower is delicious with our Mediterranean seasoning, Italian seasoning, or lemon pepper.
I also highly recommend garnishing with fresh herbs like parsley, chives, dill, or tarragon.
