🥣 Recipe instructions (step-by-step photos)

1️⃣ Step One: Prep the oven and vegetables

First, preheat your oven to 400 degrees F (200 C). Wash and dry your vegetables before cutting them.

  1. To cut broccoli: Cut the stems off the broccoli just above where they meet the stalk.
  2. To cut cauliflower: Cut off the hard stem from the cauliflower head. Next, slice the head in half and use a knife to cut away the cauliflower florets.

👉 Prepping tip! When prepping broccoli and cauliflower for roasting, cut them into similarly sized pieces. This will give them extra crunch and make them easier to eat.

2️⃣ Step Two: Season and add to baking sheet

Place prepared vegetables on a roasting pan or sheet pan.

Toss the cauliflower and broccoli with olive oil until completely coated. Sprinkle sliced garlic on top, and season with salt and pepper to taste.

👉 Seasoning tip! You can also use a bowl to toss the vegetables and seasoning, which can provide more even coating.

3️⃣ Step Three: Roast cauliflower and broccoli

Finally, roast the vegetables in the oven for about 25 minutes or until they begin to brown.

To ensure even browning, stir the broccoli and cauliflower about halfway through cooking time.

Remove roasted veggies from the oven. Serve immediately if using as a side dish, or let cool and serve as a topping for salads or bowls.

How can I meal prep roasted vegetables?

To minimize prep on cooking day, wash and cut the vegetables in advance. If you’re using roasted broccoli and cauliflower as a topping for salads or bowls, bake the vegetables up to three days ahead of time.

How do I get roasted broccoli and cauliflower to roast evenly?

Cut the cauliflower and broccoli into evenly sized pieces to help them cook evenly. Also, separate the vegetables on the roasting pan. If one vegetable is cooking faster than another, remove it to a plate and continue to cook until the other vegetable until done.
