🥣 How to make (step-by-step photos)

1️⃣ Step One: Preheat oven and prep vegetables

First, preheat your oven to 400 degrees F (200 C), then wash and cut the vegetables:

  1. To cut cauliflower: Cut stem and leave from the bottom of the cauliflower, then cut the entire head in half. Then cut the cauliflower florets form the thick white stem.
  2. To cut sweet potatoes: Cut off the ends, then cut potatoes into small 1/2 inch cubes for roasting (you do not need to peel them before roasting).

👉 Pro tip! We like to cut the sweet potatoes and cauliflower florets into similar sized pieces so they're easier to eat, have similar cooking times, and for extra crunch.

2️⃣ Step Two: Spread veggies evenly on a roasting pan

Next, place the cut cauliflowers and sweet potatoes on a roasting or sheet pan.

Toss the veggies with olive oil until completely coated. Season with sliced garlic, as well as salt and pepper to taste.

👉 Tip! We like to keep the vegetables separated on the roasting pan. Sweet potatoes can a bit take longer to bake and you can easily scoop the roasted cauliflower off the pan when it's done and keep cooking the potatoes.

3️⃣ Step Three: Roast vegetables in the oven

The last step is to roast the mixed veggies in the oven until they are tender and brown around the edges. This will take about 35 minutes, more or less depending on your oven.

To make sure the cauliflower and sweet potatoes cook evenly, stir them halfway into cooking. If the cauliflower is cooking faster than the sweet potatoes, remove it to a plate and continue to cook the potatoes until they're done.

When the vegetables are done cooking, remove them from the oven. If eating the mixed veggies as a side dish, serve them immediately. You can also let them cool and serve on top of salads or bowls.

💡 Seasoning ideas

Garlic, salt, and pepper are the simple seasonings we used for this recipe, but feel free to get spicy…with your spices. Here are some ideas:

  • Add a squeeze of citrus: sprinkle fresh lemon or lime zest over sweet potatoes and cauliflower when they are done cooking for a fresh acidic kick
  • Cinnamon and cumin: add a dash of warming cumin and cinnamon (trust us) for deep and earthy flavor
  • Paprika, chili powder, and cayenne: add some spice by roasting the vegetables with paprika and chili powder, then sprinkling a little cayenne pepper on top
