<\/p>\nA single serving in an earthernware dish<\/p>\n<\/div>\n
Inspired by the French classic Gratin dauphinois<\/span><\/span>, this version swaps out the all-potato layers for a thrifty mix of root vegetables that stretch further and add extra flavour. It\u2019s naturally gluten-free, completely vegetarian, and perfect if you\u2019re trying to cook good food on a tight budget.<\/p>\n Whether you serve it as a hearty meat-free main or as a side dish for a Sunday roast, this carrot, swede and potato dauphinoise is proof that simple ingredients can still feel a bit special.<\/p>\n My grand-daughter, who lives with us, adores potatoes and loves cream, so I made her this dish, in the picture above, for her dinner when she got back from college. She ate the lot with a look of bliss on her face! For one portion, 90ml of cream is plenty. The cream isn\u2019t very visible in the picture, but it tastes deliciously, indulgently creamy!<\/p>\n Let\u2019s talk about why this recipe works so well when money\u2019s tight.<\/p>\n Carrots, swede and potatoes are some of the cheapest vegetables you can buy in the UK. They\u2019re:<\/p>\n Swede in particular is often overlooked, but it\u2019s incredibly affordable and adds a subtle sweetness that works beautifully in a creamy bake. When you layer it with potatoes and carrots, you get a balance of soft, tender texture and gentle earthy flavour.<\/p>\n If you\u2019re trying to stretch your grocery budget, root vegetables are your best friend. They bulk out meals, reheat well, and make vegetarian dishes feel substantial rather than skimpy.<\/p>\n Traditionally, dauphinoise refers to thinly sliced potatoes baked slowly in cream and garlic until meltingly tender, with that irresistible golden top. This recipe keeps the spirit of that classic \u2014 the layering, the cream, the (optional) slow bake \u2014 but adds carrots and swede to make it more economical and a little more interesting.<\/p>\n There\u2019s no flour in a traditional dauphinoise, and there\u2019s none here either. The cream thickens naturally as it bakes, which means this recipe is naturally gluten-free without needing any substitutes.<\/p>\n It\u2019s simple food, done properly.<\/p>\n The name \u201cDauphinoise\u201d refers to the Dauphin\u00e9 region in southeastern France, where this dish is believed to have originated. However, the exact origins of Potatoes Dauphinoise are a bit murky. Some believe it was named after the Dauphin (the eldest son of the king of France) due to its regal taste and texture.<\/span><\/span><\/p>\n<\/div>\n<\/div>\n Not at all sure how to say Dauphinoise?<\/p>\n It is is typically pronounced\u00a0doh-fee-NWAZ <\/strong>(\/\u02ccd\u0259\u028af\u026an\u02c8w\u0251\u02d0z\/ in UK English). A commonly accepted, slightly simpler, or Anglicized pronunciation is doh-fee-NWAH<\/strong>. The word breaks down into three syllables: \u201cdoh\u201d (like dough), \u201cfee,\u201d and \u201cnwaz\u201d (or \u201cnwah\u201d), with the stress on the final syllable.<\/p>\n<\/div>\n Here\u2019s what you\u2019ll need to make this cheap root vegetable gratin to feed 4 as a main, 6 as a side:<\/p>\n 500g potatoes (about 4\u20135 medium)<\/p>\n<\/li>\n 1 small swede<\/p>\n<\/li>\n 2\u20133 large carrots<\/p>\n<\/li>\n 360ml double cream (or use half cream, half milk to save money)<\/p>\n<\/li>\n 2 cloves garlic<\/p>\n<\/li>\n Salt and black pepper<\/p>\n<\/li>\n That\u2019s it.<\/p>\n No expensive herbs. No specialist ingredients. Just everyday staples that work hard.<\/p>\n Some people like to add grated cheese on top, but I never do. I think it\u2019s gilding the lily somewhat. The traditional version doesn\u2019t use cheese, but of course, if you want cheese, you go right ahead and use it, there are no dauphinoise police that will come knocking at your door!<\/p>\n Swap half the cream for whole milk.<\/p>\n<\/li>\n Use whatever root vegetables you already have that need using up \u2013 as well as potatoes, carrots and swede (rutabaga) I would try any combination of celeriac, fennel, sweet potatoes, pumpkin or butternut squash, parsnip, onions, even beetroot. I have used beetroot before and it worked really well.<\/p>\n<\/li>\n Look for \u201cwonky veg\u201d or yellow-sticker reductions and use those.<\/p>\n<\/li>\n Frugal cooking isn\u2019t about deprivation. It\u2019s about being smart.<\/p>\n A smallish portion of mixed root vegetables dauphinoise<\/p>\n<\/div>\n This is a relaxed, forgiving recipe. No stress required.<\/p>\n Peel the potatoes, swede and carrots. If the vegetables are in good condition, you may not need to peel them \u2013 I haven\u2019t peeled the potatoes in the pictures. Slice them thinly \u2014 about 3mm if you can. The thinner the slices, the more evenly they cook. A sharp knife works perfectly well, but if you have a mandoline, this is its moment.<\/p>\n Crush the garlic \u2013 be generous with it.<\/p>\n To keep the cost of the fuel to a minimum, I experimented and found that there is no need to cook it for an hour and a half in an oven. Pile all the vegetables and the garlic into a microwavable dish with a lid, or put a plate on top, season and cook on full power for 5 minutes. Test with the point of a knife to see if they are tender. If not, give them another minute.<\/p>\n Lightly grease an ovenproof dish.<\/p>\n Pile the cooked vegetables into the dish.<\/p>\n Warm the cream gently in a small pan (don\u2019t boil it). Add the garlic and season well. Pour the garlicky cream slowly over the vegetables. It should just about reach the top layer but not drown it.<\/p>\n I like to sprinkle one of my favourite ingredients over the top \u2013 Aleppo pepper. It looks pretty and gives a little spicy warmth. Black pepper does just as good a job.<\/p>\n If you cannot cook your vegetables in a microwave and they are still raw, cover with foil and bake in a moderate oven for about 60 minutes 170\u00b0<\/strong>C \/ \u00a0340\u00b0F \/ <\/span>Gas Mark 3, or 150\u00b0C for a fan oven. Then remove the foil and bake for another 20\u201330 minutes until golden and bubbling.<\/p>\n If your vegetables have been pre-cooked in the microwave, this time can be reduced hugely. Bake at 170\u00b0C (fan) for about 20 minutes.<\/p>\n You\u2019ll know it\u2019s ready when a knife slides easily through the centre and the top is beautifully golden.<\/p>\n Let it sit for 10\u201315 minutes before serving. This helps it firm up and makes slicing easier.<\/p>\n Air fry at 160C \u2013 180\u2218C for 30-40 minutes, covering with foil initially if needed. Uncover and cook for a further 5-10 minutes<\/p>\n 160C for about 40\u201350 minutes (for uncooked vegetables) total is ideal to ensure the cream does not boil over and the potatoes cook through.<\/span>\u00a0<\/span><\/span><\/span><\/p>\n If you are using pre-cooked vegetables, 15-20 minutes should do it<\/p>\n<\/div>\n<\/li>\n<\/ul>\n This isn\u2019t just a side dish. It can easily be the main event \u2013 my grand daughter loves it, just as it is, with nothing else, and I must say I am pretty partial to it too.<\/p>\n If you\u2019re feeding a family on a budget, you might like to add little something. Perhaps:<\/p>\n A simple green salad<\/p>\n<\/li>\n Buttered cabbage<\/p>\n<\/li>\n<\/ul>\n It\u2019s filling enough to stand on its own, especially on colder evenings when you want something warming and comforting.<\/p>\n Because it\u2019s made from affordable root vegetables, you can feed four people generously without spending much at all. That\u2019s the kind of recipe worth keeping in regular rotation.<\/p>\n Yes \u2014 completely.<\/p>\n There\u2019s no flour, no breadcrumbs and no wheat-based thickeners. The cream reduces naturally in the oven, creating that thick, silky texture without needing anything extra.<\/p>\n If you\u2019re cooking for someone who\u2019s gluten-free, this is a safe and comforting option that doesn\u2019t feel like a compromise.<\/p>\n It\u2019s already fully vegetarian.<\/p>\n To make it vegan:<\/p>\n The texture will be slightly different, but it\u2019s still a delicious, budget-friendly bake.<\/p>\n Another reason this recipe is perfect for frugal cooking? It keeps beautifully.<\/p>\n In the fridge:<\/strong> To reheat:<\/strong> Can you freeze it?<\/strong> Batch cooking something like this can save both money and time during busy weeks. What tends to work best for me is to make a double batch, separating the batch into two and freezing one of them for another week. If I try storing what is left after dinner, too many second and even third helpings happen!<\/p>\n This makes a fabulous dish for entertaining. It tastes like you\u2019ve gone to a lot of effort when you really haven\u2019t \ud83d\ude42 And you can even make it when you have time to so so and freeze (or store in the fridge if your event is just a few days away)<\/p>\n Root vegetables are ideal because they hold their shape and soften beautifully. Potatoes, swede, carrots, parsnips and even celeriac work well.<\/p>\n Any combination that you have in the fridge. I\u2019ve also sucessfully added broccoli, cauliflower and beetroot.<\/p>\n Very. Swede becomes tender and slightly sweet when baked in cream. It balances the richness of the potatoes perfectly.<\/p>\n You can use whole milk instead, though the sauce will be lighter and slightly less rich. For best results on a tight budget, use half cream and half milk.<\/p>\n Keep the oven temperature moderate and avoid boiling the cream before baking. Slow cooking gives the best texture.<\/p>\n There\u2019s something deeply satisfying about turning basic, inexpensive ingredients into something that feels generous and comforting.<\/p>\n This carrot, swede and potato dauphinoise isn\u2019t flashy. It won\u2019t break the bank. But it will fill your kitchen with that warm, garlicky smell and give you a tray of golden, bubbling comfort food that feeds everyone properly.<\/p>\n This version, as at February 2026, will cost 58p a portion<\/p>\n And that, really, is what frugal cooking is all about.<\/p>\n Simple food. Cooked well. Shared generously.<\/p>\n Kounoupithi Yiahni or Tomato Stewed Cauliflower. A traditional Greek food<\/a><\/p>\n
