Low Carb Turnip Gratin — Vegetarian Recipe — Diet Doctor (5)


Making low carb simple


Instructions are for 6 servings. Please modify as needed.

  1. Preheat the oven to 400°F (200°C).

  2. Peel the onion, garlic and turnips. Slice everything very thinly – ideally with a mandolin or food processor.

  3. Finely chop the chives.

  4. Grease a 9" baking dish with butter and alternate slices of onion, garlic and turnip with chives and most of the cheese, saving some to go on top. Season with salt and pepper to taste.

  5. Add cream and remaining cheese on top. Bake for about 30 minutes until bubbly and golden brown.


This dish can be made dairy free if you substitute the cream with coconut milk and skip the cheese.

For the best flavor, select turnips that have smooth skin and are about the size of a tennis ball.

    I dont like turnip but I have a variation of this dish most nights - just parboil your chosen veg - I use cauli, brocc, cabbage, spinach, chard, mushrooms - place in the dish in layers then put the cream and cheese on top and bake til golden. Yummy and nice and fatty. Goes with everything - fish and meat.

    This is a great recipe, but for those who want to go lower carb try using celeriac.

    Celeriac is one of the lowcarb mega stars. Much tastier than potatoes, lowcarb and unlike other root vegetables, which store a large amount of starch, celery root is only about 5-6% starch by weight. Collins Gem calorie counter states flesh only boiled 1.9 grams of carb per 100 grams.

    Celeriac may be used raw or cooked. It has a tough, furrowed, outer surface which is usually sliced off before use because it is too rough to peel. Celeriac has a celery flavour, and is often used as a flavouring in soups and stews; it can also be used on its own, usually mashed, or used in casseroles, gratins and baked dishes. It can be roasted like a potato, giving it a crispy edge.

    I found these directions very vague - for example, when does the butter go in? Do you layer the cheese? What about the salt and pepper? I put the butter on a fork and greased casserole dish. Then I sliced it up and layered it every few layers with the turnip, onion, cheese, and gave a few grinds of salt and pepper every few layers. I did not use the garlic but rather did a couple shakes of garlic powder every few layers too. I put the heavy cream in and then the cheese on top. This turned out great, but I wanted to help others who may find these directions are not very detailed. Enjoy!

    I would never have thought of preparing parsnips this way. This was a fantastic dish.
    One of the best things about the Diet Doctor website is finding and trying new recipes and discovering a new cooking style. Thank you... Keep up the recipes..they are great.

    So, I made the turnip gratin and, instead of lamb chops, I made pork chops because they were on sale and the lamb was expensive. Now, I have eaten turnips in a stew or a casserole and they were ok, I then tried them roasted and I started to have more of a relationship with them. But, last night, when I tasted them in this dish, the turnip gratin, I fell in love with them! One could almost mistake them for potatoes! I use the shredded cheese, the Italian one, with asiago, provolone etc. I sprinkled tarragon, fresh ground black pepper and sea salt, the chunky one. I use quite a bit of garlic and whipping cream. The cheese was subtle and gooey, the tarragon offered a lovely flavour without being overpowering and the garlic blended well with the onion and cream. I am so in love with this dish and I am now thinking of what other vegetable can I try in this recipe and what other cheese can I use and see what I can come up with! On top of that, turnips have just been raised up to a higher level on my list of go to veggies!

    Just made this tonight, absolutely delicious! I used a bit of mozzarella between the layers for a bit of extra cheesiness.

    I found this recipe in an old low carb book from 1997. Almost didn't make it because of the turnips...

    There is of course more carbs per 100g in carrots or onions... So no root vegetables must mean look at the numbers more than no root vegetables.

    The directions aren’t entirely clear on a few things.
    I layered the turnips with the onions, then added chives and garlic every layer. Would add a thin layer of cheese every second layer.
    I added the butter to the top layer and melted it, then added the cheese after it had melted.
    It said to cook for 30 minutes at 400, but I cooked it for 20 minutes extra to ensure that the turnips were well cooked (turnips take a long time to cook) and they were undercooked at 30 minutes.

    Don't worry about this recipe too much. Add your own little details to make it yours. I've layered the onion, turnip, cheese, and sometimes just mixed the whole thing up...cant really tell the difference. I've used butter, Ghee, coconut oil, avocado oil for the pan greasing. Currently have made it the last 4 times with rutabaga, works perfectly. I make such a big casserole dish that I usually cover it for 30 minutes then take cover off and cook till top browning.

    Anyone have any ideas about quantities for this recipe? It looks good, but the quantities of all the ingredients are missing. Would love to try it, but how much butter, heavy cream and shredded cheese are you supposed to use?

  20. 20


    September 15 2017

    1/4 tsp cream? most recipes call for 1-1/2 cups or so. Is this correct?

  21. 21


    September 25 2017

    Check your recipe. It's changed from 1 1/2 cups to "Tablespoons" People, I think it's 1 1/2 cups. Certainly works. This is a go to dish and keeps me in ketosis if I pace myself.

    NOTE: This recipe used to say 1.25 cups heavy cream, it's much better that way!

    Glad I read the posts I was also wondering about the cream being 1/4 teaspoon.

    Totally agree on the insufficient cooking time. Definitely undercooked at 30 minutes. I cut out a square and ate it 'crunchy' because I was so starving, but put the rest back in at a lower temp (150ºC) with foil on top because it was already well browned. Hoping it will cook through in another 30 mins! Shannon had the right instinct; why do I never learn? My gratins always need more time than the recipe. Maybe my basic mandolin doesn't slice thin enough? Taste was very oniony, but, hey, the onions were also half-raw, so no wonder.

    There are two ways to speed up the cooking process. One is to part-cook the turnip slices etc in the cream in a saucepan before putting into a baking dish and the other is to part-cook in a microwave before finishing both off in the oven.

    Love this. I've added mushrooms and tuna for a really nice casserole.
