I usually build mine around cauliflower, broccoli, turnips, shallots, and garlic, but the technique works with almost any keto-friendly vegetable you want to swap in. This is genuinely a good side for any time of year.

Use a heavy, sturdy sheet pan with raised sides. Thin, lightweight cookie sheets warp under this kind of high heat.

Chef Jenn’s Take on Roasted Vegetables

Cutting every vegetable the same size regardless of type is the most common mistake here. Root vegetables like turnip and carrot take longer to cook through, so cut them smaller than quicker-cooking vegetables to help everything finish at roughly the same time.

I leave the cauliflower and broccoli pieces a bit larger than the rest, partly for even cooking and partly because bigger florets just look nicer on the plate. Toss everything with oil, salt, pepper, and whatever seasoning you’re in the mood for, then roast at 425 degrees for about 15 minutes. Check at the 10-minute mark so you don’t overcook anything, and flip everything halfway through for even caramelization on both sides.

Skip the butter here. It burns at this high a temperature and turns bitter instead of adding flavor, stick with a high-heat oil like avocado or olive instead.

This is genuinely flexible on seasoning direction. Italian seasoning leans one way, thyme and rosemary lean French, and red pepper flakes add heat if you want it. It’s also a great meal-prep dish, a big batch keeps well in the fridge for up to a week.

What You’ll Love About Roasted Vegetables

• A great meal-prep side, keeps well in the fridge for up to a week.
• Never gets boring, since the vegetable mix changes based on what you have on hand.
• Works with almost any keto-friendly vegetable, so it’s endlessly adjustable.

Ingredients

• Cauliflower – Cut into fairly large florets.
• Broccoli – Cut into fairly large florets.
• Turnips – Peeled and cut smaller than the cauliflower and broccoli, since they take longer to cook.
• Shallots – Peeled and cut into wedges. Milder than onion, though onion works too.
• Garlic – Peeled and smashed.
• Olive oil – Or avocado oil, both handle high heat well. Skip butter, it burns at this temperature.
• Salt and pepper – To taste, plus any additional seasoning you like.

Prepare the vegetables and cut them into chunks, keeping root vegetables like turnip a bit smaller than the rest.

Mix the oil with the salt and pepper in a large bowl.

Add the vegetables to the bowl and toss well to coat evenly with the seasoned oil.

Spread the vegetables out on a heavy sheet pan in a single layer.

Roast in a 425°F oven for about 15 minutes, checking at the 10-minute mark and flipping halfway through for even caramelization.

Serve hot.

Make It A Meal

This works well with almost anything off the grill, like Kefta Beef Kabobs or Bacon-Wrapped Pork Tenderloin.

For a second vegetable side on the same table, Skillet Cabbage with Bacon pairs well too.

Storage

Store in an airtight container in the fridge for up to 7 days. Reheat gently in a skillet or the microwave. Freezing is not recommended, the vegetables lose texture and moisture during freezing and thawing.
