How to Microwave Turnips

How to Microwave Turnips (Cubed Method)

Turnips have a reputation for being a slow, boil-it-forever kind of vegetable, but that’s really only true on the stovetop or in the oven.

The short answer is turnips microwave beautifully in under 10 minutes — cube them, add a splash of water, cover, and cook on high.

I’ve leaned on this method on plenty of weeknights when I didn’t want to heat the whole oven for one side dish.

If you’ve got more turnips than you can use this week, it’s worth learning how to freeze turnips so you’ve always got some ready to go.

Wash and Prep

Give your turnips a good scrub under cold water, since they often come with garden soil clinging to them.

Peel them, then cut into cubes around 1/2 to 3/4 inch — smaller, even pieces cook faster and more consistently.

Cook and Season

Place the cubes in a microwave-safe dish and add about 2 to 3 tablespoons of water.

Cover with a microwave-safe lid or vented plastic wrap, then microwave on high for 4 minutes.

Stir, then microwave another 4 to 6 minutes, until a fork slides in easily.

Let the turnips rest a minute, then season with salt, pepper, and a pat of butter.

Should You Peel or Cut Turnips Before Microwaving?

This is where a lot of people get stuck, and it depends on what you’re trying to do.

If you want to actually cook turnips through, peeling and cubing first is the faster, more reliable route — heat just doesn’t penetrate a whole vegetable quickly.

That said, some cooks microwave a whole turnip briefly first purely to soften the skin, which makes peeling easier afterward.

A short 2 to 3 minute zap on the whole turnip is enough to loosen the skin without cooking the inside at all.

In my experience, trying to fully cook a whole, unpierced turnip straight in the microwave just leads to a rock-hard center and a mushy outer layer.

The same logic applies to other dense vegetables — see how to microwave broccoli for another quick-prep, high-heat approach that rewards cutting first.

How to Microwave a Whole Turnip (Skin On)

Sometimes you genuinely want a whole turnip — maybe you’re roasting it afterward, or mashing a big batch later.

You can microwave a whole turnip with the skin on, but expect it to take 10 to 18 minutes depending on size.

Start by piercing the skin all over with a fork or paring knife, just like you would a potato, so steam has somewhere to escape.

Place it on a microwave-safe plate — no water needed — and cook on high for 10 minutes if it’s small to medium, around 3 inches across.

Turn it over halfway through so it cooks more evenly on both sides.

Larger turnips, closer to softball size, can take 15 to 18 minutes, and it’s worth checking with a fork every few minutes near the end.

Let it rest, still covered, for 2 to 3 minutes before cutting — it keeps cooking a little from residual heat.

Turnips behave a lot like beets when microwaved whole; if you want a side-by-side approach, our guide to how to microwave beetroot walks through the same whole-vegetable method.

My Turnip Is Only Partially Cooked — Now What?

This happens more than you’d think, especially with whole turnips or unevenly cut cubes.

If your turnip is still firm in the middle, just put it back in for more time in short bursts.

Add 1 to 2 minutes at a time, checking with a fork after each round, rather than guessing at one long cook time.

If the dish looks dry, splash in another tablespoon of water before covering and continuing — dried-out turnip pieces just toughen up, they don’t soften.

One thing that trips people up is cutting some cubes small and others nearly double the size, so they finish cooking at very different rates.

Microwaves also have hot and cold spots, so stirring the dish or rotating a whole turnip partway through makes a real difference.

Tips for the Best Microwaved Turnips

A few small habits make a noticeable difference once you’ve got the basic method down.

According to USDA FoodData Central, raw turnips provide a decent amount of vitamin C, though cooking — including microwaving — can reduce heat-sensitive nutrients such as vitamin C to some degree.

Use a Dish With a Real Lid

A shallow bowl with a sealable lid, or a casserole dish with a glass lid, traps steam far better than loose plastic wrap.

That trapped steam is what actually softens the turnip, so a good seal matters more than most people assume.

Bring Out the Natural Sweetness

Once cooked, a knob of butter and a pinch of nutmeg brings out the turnip’s mild sweetness.

For a creamy mash, swap in Greek yogurt instead of butter and mash everything together while it’s still warm.

Don't Toss the Tops

If your turnips came with their green tops attached, save them — they cook up a lot like spinach and add another nutritious element to the meal.

Microwaving Turnip Greens (Fresh and Frozen)

Turnip greens are worth cooking on their own, whether they came attached to your turnips or in a separate bag.

For fresh greens: rinse well, add to a covered microwave-safe bowl with a tablespoon of water, and microwave 2 to 3 minutes, until wilted.

Frozen turnip greens go in straight from the freezer — there’s no need to thaw first.

Microwave frozen turnip greens in a covered dish with about 2 tablespoons of water for 5 to 6 minutes on high, breaking up the block and stirring halfway.

Cooking greens briefly, rather than boiling them for a long stretch, helps them hold onto more of their color and nutrients.

The technique is close to how you’d handle other frozen vegetables — see how to microwave frozen peas for a similar frozen-to-table method.

Reheating Mashed Turnips

Mashed turnip reheats well, whether you’ve got a microwave handy or not.

In the microwave: spread the mash in a shallow dish, add a splash of milk or broth, cover, and heat in 1-minute bursts, stirring between each.

No microwave? Mashed turnip reheats just fine on the stovetop instead.

Put it in a small saucepan over low heat with a splash of milk or broth, and stir frequently for 5 to 8 minutes until hot throughout.

An oven works too — cover a baking dish with foil and warm at 350°F for about 15 to 20 minutes.

Whichever method you use, the USDA recommends reheating leftovers to an internal temperature of 165°F.

The stovetop-or-oven fallback works the same way for other leftovers meant for a microwave — our guide to how to reheat pasta bake covers the same swap for a heavier casserole dish.

How to Cook Turnips Without a Microwave

If you don’t have a microwave, or you just prefer a stovetop, turnips take well to a few other methods.

Boiling

Cut into even chunks, cover with cold salted water, bring to a boil, and simmer 15 to 20 minutes until fork-tender.

Steaming

Steam cubed turnips over simmering water for 10 to 15 minutes — this keeps more flavor than boiling, since the pieces aren’t sitting in water.

Roasting

Toss cubes with oil, salt, and pepper, then roast at 400°F for 25 to 35 minutes, until browned at the edges.

Roasting is where turnips really shine flavor-wise, developing a nutty, caramelized sweetness the microwave just can’t replicate.

Why (and Why Not) to Microwave Turnips

Microwaving turnips has real advantages, but it’s not the whole story.

Speed is the biggest win — roughly 8 to 10 minutes in the microwave versus up to 30 minutes in the oven.

There’s also less cleanup, since you skip pots, pans, and baking trays entirely.

On the downside, prep still takes a few minutes of washing, peeling, and cutting before anything goes in the microwave.

It’s also best suited to smaller portions, since large batches or big chunks won’t cook evenly.

And you lose the color and nutty caramelization that oven-roasting gives turnips — the microwave just steams them.

Compare that to a vegetable like baby corn, where how to microwave baby corn takes barely any prep at all, since there’s no peeling involved.
