    Ingredients for roasted broccoli and cauliflower

    • Cauliflower and broccoli: Use fresh for the best results. Break them into florets before tossing them with the seasonings and roasting.
    • Oil: To help the veggies crisp up and brown. Olive, canola or vegetable will all work well.
    • Garlic: Garlic adds a great flavor that isn’t too overpowering. In a pinch, you can use a little garlic powder instead.
    • Parmesan: Use freshly grated parmesan for a cheesy bite. Make the dish vegetarian by using a rennet-free parm, or omit it for a vegan side dish.
    • Seasonings and herbs: Italian herbs, salt, and pepper. You can also add chopped fresh parsley, and a drizzle of lemon juice.

    How to roast broccoli and cauliflower

    • Preheat the oven to 400 degrees F. Line a large baking sheet with parchment paper.
    • Mix the broccoli and cauliflower florets in a large bowl. Add the olive oil, minced garlic, half of the parmesan cheese, and season with Italian herb seasoning, salt and ground black pepper. Toss again.
    • Arrange the veggies in a single layer on the lined baking sheet pan, giving them plenty of room to breathe. Bake for 18-20 minutes, until the edges are browned. (Toss halfway through for more even cooking – optional but works better.)
    • Right before serving, toss with remaining parmesan cheese, and sprinkle with additional salt & pepper to taste if desired.

    Can you make it ahead of time?

    This baked broccoli and cauliflower recipe is best enjoyed as soon as it’s ready for the best flavor and texture. You can toss the veggies in the oil and seasonings the night before and leave them covered in the refrigerator till ready to cook. If you do have leftovers, they will keep well for around 3 to 4 days in the fridge and can be reheated at 350F for 10 minutes to warm through.

    Can you use frozen broccoli and cauliflower?

    I’ve found that fresh veggies are best used in this recipe, but you can use frozen if that’s what you have to hand. Don’t defrost them first, just toss them in the oil, garlic, parmesan, and herbs and add an extra couple of minutes to the cooking time.

    TIPS FROM NELI’S KITCHEN

    Recipe Notes and Tips

    • Pat the broccoli and cauliflower dry after washing. If wet, they will steam rather than roast and be soft and mushy rather than crispy.
    • Make sure that the florets are well coated with the oil so that they get crispy all over.
    • Toss the veggies halfway through cooking to allow them to cook more evenly.
    • Mix up the seasonings to suit whatever meal you are serving alongside. Different herbs or spices like paprika all work great.
