There's nothing like roasting vegetables to bring out their flavor. And while it's common to use olive oil and salt and pepper, you can add other ingredients, as well.
Inspired by my Mediterranean cauliflower salad, this Mustard Roasted Cauliflower recipe stars tangy Dijon mustard. Along with garlic and fresh dill, it elevated the flavor of this cruciferous vegetable.

Serving suggestions
Mustard Roasted Cauliflower is quite versatile and goes with a wide variety of dishes from lemon artichoke pasta to chickpea rice pilaf to lentil meatloaf.
Or you can add it to a squash and quinoa buddha bowl or chickpea and potato bowl. I've even been known to enjoy the leftovers as a snack.
Storing
Leftover roasted vegetables can be refrigerated in an airtight container for 3 to 4 days.
Reheat them in a microwave-safe bowl or enjoy them cold straight from the refrigerator. This Dijon cauliflower is a wonderful addition to salads topped with Mediterranean green olive salad dressing.
Recipe FAQs
Make sure to spread the florets out evenly on your baking sheet and avoid overcrowding to ensure even roasting.
More nutrients are retained with dry cooking methods such as roasting, grilling, and stir-frying.
This recipe can be prepared in your air fryer by cooking at 375 degrees for 20 minutes, tossing halfway through. Be sure not to overcrowd the basket. You may need to cook the florets in two batches.
This recipe calls for one head of cauliflower, which is about 4 cups.

Hi would this work without the dill or with another herb? I've got a family of non dill likers (except me). Or would you suggest just a bit of dried dill added to the sauce instead to give it a little dill flavour without the very obvious dill garnish?
Amy Katz says
You can use a different fresh herb such as parsley. (Or you can leave the herbs off entirely and just add some fresh dill to your portion only.) But this dish is still delicious without the herbs. I hope you enjoy it, Korina!
