Best Time to Add Oil to Roti Dough: Tips for Softer Flatbreads

Soft, flaky, melt-in-the-mouth rotis aren’t some magic trick you need years in an Indian grandmother’s kitchen to master. Yet, one subtle detail keeps slipping under the radar even for seasoned roti-makers: when exactly do you add oil to the dough? This tiny timing decision doesn’t seem life-altering until you realise those pillowy, restaurant-style rotis are totally doable at home — if you play your oil cards right. My mum used to eyeball the oil, tossing it in during kneading “when it feels right.” I’m not quite that fearless. Instead, after much trial, error, and actual science reading, I know there’s a clear answer. By the way, Darren can tell who's made the roti by the softness alone, so there's no cheating at our dinner table.

Why Does Oil Matter in Roti Dough?

Let’s get straight into it. Oil isn’t just there for shine. It’s all about texture: think gentle separation, moistness, and preventing that dreary, dry chew. There’s some neat food chemistry at work. Oil coats wheat flour particles, limiting gluten development during kneading. Not enough: your rotis turn out dry and papery. Too much: they get heavy, almost greasy.

Here’s the interesting bit. Recent tests by Cook’s Illustrated found adding fat directly to flour before you pour in water makes wheat proteins less eager to tangle up and form strong gluten strands. That’s what keeps rotis soft and their layers delicate. If you add oil early, you’re essentially “shortening” the flour—hence the baking term—and get weaker gluten, softer rotis. Mixing oil later, after water, gives a completely different result. You’ll notice the surface of your dough looks oily, but inside, it can be oddly tough.

Home cooks in Punjab swear by ‘moyan’—a splash of oil or ghee rubbed into flour first—claiming it’s the only way to guarantee soft rotis that puff up perfectly. It’s not just tradition, but a wise hack. And if you doubt the fuss, just try making roti both ways (oil before and after water), and notice the difference in how easily the dough rolls out and how soft it stays even hours later.

If you’re curious about data, a 2022 survey of over 200 Indian home cooks showed 78% add oil before water and swear by its results, while only 12% prefer kneading it in at the end. That’s a pretty clear winner, isn’t it?

Traditional Method: Adding Oil Before Water

So here’s the step-by-step most Indian cooks (and their mums and grandmums) use. The classic method is to always add oil before pouring in water:

• Start with your wheat flour in a wide plate or bowl.
• Add salt (if you use it) and blend well with flour.
• Add a tablespoon or two of oil (or ghee, if you want extra flavour).
• Use your fingers to rub in the oil until the flour looks like damp bread crumbs.
• Now slowly add water while kneading to form a soft, pliable dough.

This pre-rubbing does more than moisturise. It stops gluten from toughening up too soon, so kneading gets easier and your dough stays smoother. It also results in rotis that remain soft even after sitting for hours, which in my house means they’re still perfect after Darren gets home late from cricket practice.

If you want to impress anyone—maybe that nosy neighbour who thinks only her rotis are soft—try this out. Mix just enough oil so the flour has that sandy feel, but not so much it turns sticky. I find 1–2 teaspoons per cup of flour is the sweet spot.

Here’s a quick table, based on actual rotis made in Brighton last month, comparing oil addition timing and its effect on softness:

That dramatic softness boost isn’t just feel-good—it survives taste tests and lunchbox checks alike. I’ll say it: skip the oil at your peril.

Modern Variations: When to Add Oil Later

Things get interesting in busy kitchens. Some cooks, in a rush (raising my hand), forget the oil entirely and panic-splash it onto finished dough. Does it help? Slightly. Here’s what happens: oil on worked dough mainly stops sticking, but it does little for that pillowy internal texture. It's like applying lotion after your skin’s already dry—better than nothing, but nowhere near as good as being preemptive.

That said, in certain regional recipes, oil does intentionally come in at different stages. In Gujarat, theplas (yep, those spicy flatbreads) often have extra oil kneaded in halfway. When you want crispier, more durable rotis—like those meant for travel—some cooks go heavy with oil after kneading, or just before rolling, for a totally different texture. This gives you less softness, more durability and a pleasantly chewy bite that’s perfect for days-long train journeys.

If gluten matters to you (perhaps you’re aiming for higher fibre or a less processed flour), you might also experiment with timing. Here’s the truth: whole grain flours benefit even more from early oil addition because the bran is tougher and needs that extra softness. If you’re into nutrition, try olive oil or cold-pressed groundnut oil for a punch of healthy fats. And on that note, don’t worry if you’re vegan—oil or plant-based ghee does exactly the same job as dairy ghee here.

Modern appliances like food processors also change the game. If you add oil early in the processor bowl, you still get those classic, soft results but with less manual squeezing. Just don’t skip the “resting” step; it’s as vital as the oil itself.

One respected chef on BBC Good Food put it best:

“A dash of oil rubbed in before the water makes all the difference, allowing the cooked roti to stay soft even after hours in the breadbox.”

Troubleshooting: Getting the Oil Balance Just Right

Now for the part everyone messes up at least once. Too much oil and your dough turns greasy, can’t hold shape, and is nearly impossible to roll out thin. Too little and you’re back to dry territory. Here’s how to get spot-on, every time:

• Measure your flour—don’t just guess. Even a small cup is fine if you keep the ratios the same.
• For each cup (around 120g) of whole wheat flour, add 1 to 2 teaspoons oil. For softer, slightly richer rotis, go up to 2 teaspoons per cup. For everyday soft but sturdy rotis, 1 teaspoon works a treat.
• Add the oil when you first handle the flour, and rub it in thoroughly. If it doesn’t feel dampish, you can add a smidgen more—just avoid making the flour sticky or shiny.
• The dough should look evenly moistened, and you’ll feel how easily it comes together with water.
• If you only remember the oil after kneading, it’s not a disaster. Make a mental note for next time and maybe brush oil onto the cooked roti’s surface for extra support!

One last trick for show-stopper softness: after kneading, cover your dough and let it rest for at least 30 minutes. No matter when you added oil, this rest gives the gluten a breather and makes everything easier to roll (and eat).

If you want numbers, a 2023 study from India’s National Institute of Food Technology found that rotis made with 2% oil by flour weight retained 60% more surface moisture after three hours than those with no oil. That’s the secret behind those lunchbox rotis your friend’s mum made, still soft at 4 pm.

Here’s my own standard roti recipe, Brighton-tested and Darren-approved:

• 1 cup atta (whole wheat flour)
• 1/4 tsp salt (optional)
• 1–2 tsp sunflower oil (or ghee, for extra luxury)
• 1/3–1/2 cup water, as needed

1. Mix flour and salt in a bowl. Add oil, rub it in until you feel that sandy texture.
2. Drizzle in water as you knead, aiming for a soft, not sticky, dough.
3. Let dough rest, covered, at least 30 minutes.
4. Roll, cook, and enjoy the applause from your favourite critic—or partner, if you’re lucky like me.

Getting your roti dough timing right is more than just a kitchen habit—it’s soft, comforting evidence you care enough to master the details. Next time you hear the sizzle of your flatbread, you’ll know exactly when to pour in that gold, and why it matters. Soft roti is never an accident; it’s all in the timing, a pinch of patience, and that one, simple splash of oil.
