👉 Ready to learn how to bake potatoes and cauliflower? Let’s do it!

🥣 Ingredients

  • Potatoes: one pound of potatoes, I like waxy red or new potatoes
  • Cauliflower: one large head of cauliflower
  • Garlic cloves: use fresh garlic cloves, cut into thin slices
  • Olive oil: adds flavor and helps your vegetable to brown in the oven
  • Salt and pepper: adds a touch of flavor
  • Recommended tools: sheet pan, knife set, cutting board

🥣 Recipe instructions (with step-by-step photos)

1️⃣ Step One: Prep vegetables

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

  1. To cut potatoes: Remove any spuds and cut into 1 inch pieces
  2. To cut cauliflower: Cut the stem from the cauliflower head. Slice the head in half and then cut away the cauliflower florets.

👉 Prepping tip! Cut your potatoes and cauliflower into similarly sized pieces. This will help them roast evenly and give them extra crunch.

2️⃣ Step Two: Season vegetables

Place prepared vegetables on a sheet pan or roasting pan.

Toss the cauliflower and potatoes with olive oil until evenly coated. Season with salt and pepper to taste, and add sliced garlic on top.

3️⃣ Step Three: Roast vegetables

Bake the vegetables in the oven for about 25 minutes or until lightly browned.

To ensure even roasting, stir the potatoes and cauliflower halfway through cooking time. If the cauliflower is cooking faster than the potatoes, remove it and let the potatoes cook a bit longer.

Remove the pan from the oven. Serve your vegetables immediately if using as a side dish, or let them cool and then use as a topping for salads or bowls.

  • Use fresh herbs: top your veggies with seasonal herbs and/or toasted nuts
  • Add some spiciness: if you like it hot, toss your veggies with hot pepper sauce, or top with red pepper flakes

Eat cauliflower and potatoes in season! The best time to make this recipe is when both vegetables are in season! In most areas of the U.S., cauliflower is available in late summer and early fall. Potatoes are available year round in most places. Click here to find out when produce is in season where you live.

Reduce waste by using your vegetable scraps! Did you know that cauliflower leaves are edible? Simply add them to soups or salads. The ends of your potatoes can also be eaten – just leave them on rather than trimming them off! If you prefer to cut off the ends, you can compost them or use them in a vegetable broth.
