Balsamic cauliflower ingredients

  • Cauliflower (fresh or frozen) – be sure to cut the cauliflower up into similar bite size pieces to ensure even cooking.
  • Red bell pepper – adds some sweetness to the dish. Optional – see alternatives below.
  • Balsamic vinegar – be sure to use a vinegar you enjoy that isn’t too acidic
  • Olive oil – olive oil helps to cut through the acidity of the balsamic vinegar and helps the cauliflower caramelize when cooking.
  • Spices: Italian seasoning, Salt, Garlic powder – I like to use garlic powder so the garlic doesn’t burn. Use your favorite herbs here – basil, oregano, mint, marjoram, thyme, rosemary

Top tips

  • You can use fresh or frozen cauliflower for this recipe! I actually love having a few bags of frozen cauliflower on hand so that I can skip the step of cutting the cauliflower from the stalk.
  • Be sure to line your baking sheet with parchment paper! This really helps make clean up a breeze! If you don’t have parchment paper, you could use foil as well. If you don’t have parchment paper or foil, you may want to use a glass baking dish instead for easy clean up.
  • Use a big enough baking sheet! When roasting veggies, you want to ensure they have some room to spread out so they aren’t steaming but instead roasting. This can be achieved by using an extra large baking sheet or dividing the cauliflower between two baking sheets if necessary. Be sure to rotate the pans in the oven if you are using 2.
  • Be sure to cut the cauliflower into similar size pieces so it can cook evenly. This applies to fresh or frozen cauliflower florets.
  • Use a balsamic vinegar you actually like the taste of. I have to admit I’ve had a few balsamic vinegars that were 100% terrible and it ruins a dish. I love the aged balsamic from Trader Joe’s or they have a great one at a good price from Thrive Market too!

What other veggies can you roast with balsamic vinegar

I love the simplicity of just the cauliflower and red bell pepper. This is because I almost always have these veggies on hand at my house. Some other good veggies to roast are:

  • Carrots
  • Brussel sprouts
  • Onions (white or red)
  • Asparagus
  • Radish (halved)
  • Parsnips
  • Eggplant
  • Sweet potatoes
  • Butternut squash
  • Grape tomatoes

Note: When you are adding the balsamic to the pan, if you are using eggplant be sure to coat that last as eggplant is known to absorb a ton of liquid and you likely won’t have any balsamic for the rest of the veggies.

Other spices you could add

  • Herbs de Provence
  • Za’atar seasoning
  • Fresh herbs like mint, oregano, rosemary, dill (finely chop these)
  • Fresh basil, flat leaf parsley (great for finishing the dish) add after cooking.

FAQs

What is the best temperature for roasting veggies?

I personally love 425F for roasting veggies. This temperature allows the veggies to get caramelized edges without having to be in the oven for too long.

What is the best way to cut cauliflower

Start by cutting off the green leaves so you can see the stalk vs. the florets on the bottom of the cauliflower.

With the stalk facing you (and the florets on the cutting board), use a sharp knife and trace around the stalk (this will cut away all of the sides at once). You will be left with just the top portion of the florets attached).

Steps on how to cut a head of cauliflower.

Cut the top part of the florets from the stalk. Now you have large chunks of cauliflower to work with.

Break the florets down into bite size pieces. You want them to be similar sizes so they don’t burn or undercook.

Can you make this ahead of time?

Roasted cauliflower is best right out of the oven. If you need to make it ahead, you will probably want to reheat it under the broiler 2-3 minutes (don’t use parchment paper for this) or in the air fryer 390F for 5 minutes (possibly in batches depending on the size of your air fryer).

You can also prep everything ahead so that when it’s time to cook, all you have to do is put it in the oven. For this you can cut the cauliflower or open the bags of frozen cauliflower and cut down any that are large. Place on a parchment paper lined baking sheet and store in the fridge. Make the balsamic dressing and store in the fridge. When it’s time to cook simply place the baking sheet in the oven and follow the rest of the directions.

How to store leftover roasted balsamic veggies

Fridge: Store leftovers in the fridge up to 4 days. See my note above about reheating. Roasted veggies are also great on salads cold!

Freezer: the texture of these will change when frozen. If you have to freeze them, I suggest using them in soup or a dish where the texture is not as important. If you want to try to eat them out of the freezer, defrost and reheat in the air fryer or broiler.

Substitutions

  • Cauliflower and red bell pepper: You can use any of the veggies listed above to replace cauliflower or red pepper. The cooking times may vary based on the veggies you use. Hard winter veggies like butternut squash, sweet potatoes, onions, brussel spouts, carrots and parsnips will probably cook in the same amount of time as stated. Other veggies like asparagus, tomatoes, eggplant, fennel will likely cook up in about 20 minutes total roasting time. You can add the marinade directly to those veggies before roasting.
  • Balsamic vinegar: You can also use a balsamic glaze. This is much thicker than balsamic vinegar and is a bit sticky. It could take a little longer to combine with the veggies but would impart an even deeper flavor.
  • Italian seasoning: see other herbs you could add above or omit completely.
  • Salt: This helps elevate all the flavors. If you think you don’t like vegetables it’s likely because you aren’t salting them. Use your favorite “no salt added” seasoning here.
  • Garlic powder: You could also use fresh garlic however, it may burn a bit in the oven which is why I use garlic powder. If you are low fodmap or cannot tolerate garlic you can omit or use garlic infused olive oil (1 tbsp) in place of garlic powder.

Notes

How to reheat:
Roasted cauliflower is best right out of the oven. If you need to make it ahead, you will probably want to reheat it under the broiler 2-3 minutes (don’t use parchment paper for this) or in the air fryer 390F for 5 minutes (possibly in batches depending on the size of your air fryer).
Storage: 
  • Store leftovers in the fridge in an airtight container for up to 4 days. See reheating instructions above. 
  • Cauliflower will get mushy when freezing. I don’t recommend storing it this way. If you have to freeze it, it will likely be best served in a soup or a dish where the texture is not as important. 
How to cut cauliflower:
  • Start by cutting off the green leaves so you can see the stalk vs. the florets on the bottom of the cauliflower.
  • With the stalk facing you (and the florets on the cutting board), use a sharp knife and trace around the stalk (this will cut away all of the sides at once). You will be left with just the top portion of the florets attached).
