Whether you are just getting acquainted with turnips or you are a long-time fan, one thing is certain, roasting turnips with onion is a simple, yet delicious way to enjoy them. This is a perfect low carbohydrate side dish that goes great with proteins like chicken, steak, or fish. Itโs also a great vegetable dish that can take the place of a starch and veggie at the same time. The combination of sweet and tangy balsamic vinegar and earthy turnip and onion flavor will have your taste buds singing! With only five main ingredients, a few spices and 30 minutes of cooking time, youโll be able to enjoy this delicious side dish in no time. The nutritional value of turnips is also a huge bonus. Letโs get cooking!
Why cook turnips?
Iโll be honest. The only reason I even tried to cook turnips was because my husband, the gardener of the house grew them! Why did he grow them you ask? Because he got free seeds thrown into a pack with other seeds he ordered. Ha! True story. Ok, well now for the other reason I decided to mess around with these root vegetables; theyโre low carb! I love potatoes, donโt get me wrong, I really do. Just look at my site and youโll see plenty of potato dishes from Cheesy Au Gratin Potatoes to simple garlic roasted red potatoes. The problem is, I have made a change to my diet in recent months to help lose weight and the only way I could do it is to lower my carb intake. Thatโs where turnips come in and are perfect for people like me.
Health Benefits of Turnips
As mentioned previously, turnips are a great starch alternative that are low carb. The beauty of this cruciferous vegetable is that a cup of turnips has only about 36 calories, whereas a cup of potatoes has about 100 calories. The carbs in about a cup of turnips is 8 grams vs about 26 grams per cup of diced potatoes. Besides being loaded with loads of vitamins like calcium, magnesium, potassium and vitamin C, theyโre a great source of fiber, eye, bone and heart health, regulating blood sugar, and a great veggie for cancer prevention. You can check out more benefits on WebMDโs Health Benefits of Turnips here. This is a perfect side dish for a Keto or low-carb diet.
How to Prepare Roasted Turnips
So, you pretty much prep these root veggies like you would roasted potatoes, but with this turnip recipe I add a little extra goodness to it. A little butter and caramelized flavor with the onions, balsamic vinegar and butter. You do not to need remove the outer peel, but if there are parts you want to remove a vegetable peeler works great. I add the turnips, onion, olive oil and balsamic to a large rimmed baking sheet or a 9 x 13 Pyrex dish works great too.
Oven or Pellet Smoker Roasting
My preference for cooking this recipe is the pellet smoker, i.e. Pit Boss or Traeger. We have a Pit Boss that we are obsessed with. Since my turnips are garden grown, in the summer, the outdoor smoker is ideal. No heating up the house and the turnips turn out amazing this way. Give the turnips and onion a good toss with the oil and vinegar and then add your spices. Stir it all again until everything is coated well with the seasoning. Spread it out evenly in your baking dish and top with your cubes of butter. Now, youโre ready to roast the turnips, uncovered in your oven or pellet grill. My preferred method is the pellet grill to get the best result; it makes them a little smoky, gives the turnips great color and that nice caramelization, that makes this turnip recipe so delicious!
Roasted Turnips with Onion Ingredients
- Medium Purple Top Turnips- I use purple top white globe turnips for this recipe. About 3 medium 3 inch wide turnips, more precisely 1.5 lbs. If you have all sorts of sized turnips, which is highly likely if theyโre growing in your garden, then I do recommend weighing them with a food scale. I use white turnips with purple tops, turnip greens cut off. Donโt discard those turnip greens, cook them! Thereโs a great recipe for these leafy greens from AddaPinch.com, Spicy Skillet Turnip Greens Recipe you can try out.
- Sweet Onion- This turnip recipe is so much better in my opinion with sweet caramelized onion. You can go without, but I donโt recommend it. Youโll be missing out.
- Balsamic Vinegar- The addition of balsamic vinegar helps cut down on some of the bitter flavor of turnips with itโs natural sugars. If youโre following a low carb or Keto diet, just watch the balsamic vinegar you use. Some have more carbs than others.
- Olive Oil- I just like good olโ Extra Virgin olive oil. Avocado oil is great as well for roasted vegetables, especially when cooking in high temperatures.
- Garlic Powder- I love granulated garlic which is about the same, just a bit more coarse and concentrated in taste.
- Sea salt- My go to cooking salt, but you can use kosher salt as well, just be sure to adjust to your liking at the end of cooking and taste before serving.
- Pepper- Standard fine or coarse ground black pepper is great.
- Smoked Paprika- If you donโt have smoked paprika, standard sweet paprika is fine. It just wonโt have as much of the smoky flavor if thatโs what you like.
- Unsalted Butter- Add about 4 tablespoons of butter to the dish before roasting, this is a great way to get a little more of the caramelized flavor and bring out the natural sweetness of the onion as well.
- Optional: Drizzle just a little lemon juice on the turnips after roasting, just before serving. Also, if you have a flourishing herb garden you can toss in some fresh herbs. Some chives, thyme or dill go great with turnips.

Oven Roasting

This did not make it from the kitchen to the dining room table. My wife and I shoved it in like potato chips or Doritos. So good. We had three of these huge purple tops from our CSA and did not know what to do. Glad I settled on this to get rid of the first one. Donโt know how long we will wait before we subject the next two to the same treatment.
Ha! Awesome, Alexander! I love to hear this and I LOVE your vivid description. Thanks so much for taking the time to share your thoughts on the roasted turnips. Enjoy!
I have eaten a turnip fresh out of the garden that was almost as sweet an apple. If you can find fresh ones they are very good. From the store not as good. Have not tried them this way YET.
Robert, I have to say, I have never tried a turnip fresh out of the garden. That is something! I hope you try them this way as well. Thanks for sharing.
Is there any way to make these in the air fryer?
Lisa, You might be able to air fry these turnips, but Iโve never tried so I could not give you temperatures or times. If I do, I will definitely post it.
Honestly, a challenging vegetable to get delicious flavor out of to begin with! But this recipe intrigued me enough to give it a whirl. my feedback is that the turnips needed longer than 30 minutesโmaybe 10 mins more- in the oven to become tender but the onion only need around 25, so If Iโm making this again I pop the turnips in the oven first and around 10 minutes in, Iโll toss in the onion slices, also the turnips are a tad bitter even with the addition of the balsamic vinegar, so half way through I added some sugar, Iโd probably add the sugar in the beginning the next time. overall itโs simple enough with accessible ingredients to give it a try and I didnโt hate it, and I usually hate turnips!
Shasta, thanks for the feedback. Iโve always used homegrown turnips for this dish and as some may say, โnot all turnips are the same.โ Ours are probably sweeter and more tender than store-bought. You should definitely add more time if your turnips need it. I like the onions how they turn out with 25-30 minutes roasted, but you should adjust yours if itโs too much for you. Youโre welcome to add some sugar if you need them sweeter, but the point of this recipe is to keep the carbs down so I choose not to add more sweetener. I appreciate your feedback though and Iโm glad you at least didnโt hate the turnipsโฆlol.
I chose this recipe based on the reviews but there are none in the post. Itโs always nice to see what others have said and what additions they have suggested.
HmmโฆIโm sorry I have no control over that, but there is actually a comment below the recipe. Thanks for checking it out. Hopefully you give it a try!
