There are afternoons during Navratri when you’re between meals, when lunch was hours ago and dinner is still hours away, and what your body really wants isn’t another full dish but something to snack on. Something crispy. Something you can eat with your hands. Something that doesn’t feel like fasting food but still follows all the rules.
Made from thinly sliced shakarkandi (sweet potatoes) and cooked with approximately 85 percent less oil than traditional deep-frying, these chips deliver the satisfying crunch your palate has been missing since Chaitra Navratri started on March 19.

What Exactly Are Sweet Potato Chips for Vrat?
Sweet potato chips—shakarkandi chips—are thinly sliced sweet potatoes (Ipomoea batatas) that are air-fried or oven-baked until crisp, then seasoned with rock salt (sendha namak) and optional vrat-friendly spices. They’re the fasting adaptation of the popular commercial snack, made without grains, without regular salt, and with a fraction of the oil that deep-frying would require.
The method is simple in concept: slice thin, dry thoroughly, cook at high heat in a single layer until golden and crisp. But as with most simple things, the execution is where technique separates good results from great ones.
What makes these particularly valuable during Navratri is that they address a specific gap in fasting food: crunch. Most traditional vrat dishes are soft—sabudana khichdi, dahi aloo, kuttu puri, vrat rice idli. All delicious. All comforting. But after a few days of eating soft, yielding foods, your palate starts quietly demanding texture. Something that resists when you bite it. Something that cracks.

Why Sweet Potato Chips Are Perfect for Navratri Snacking
Significantly lower oil than deep-frying. Air-frying uses approximately 80 to 85 percent less oil than traditional deep-frying. For a batch that would require 100-150ml of oil if deep-fried, you’re using just 5-10ml with air-frying. During fasting when you’re trying to eat lighter and avoid heavy, greasy foods, that reduction matters enormously.
High fiber for digestive support. With approximately 4 grams of fiber per 30-gram serving (14 percent of daily value), sweet potato chips help prevent the constipation that often comes with restricted diets. Fiber also enhances satiety—you feel fuller longer, which is exactly what you need when meals are spaced further apart during fasting.
Exceptional vitamin A content. Sweet potatoes are one of nature’s richest sources of beta-carotene, which your body converts to vitamin A. Approximately 14,000 IU per serving translates to roughly 400 percent of daily value. This supports immune function and eye health—particularly relevant during Navratri when you’re spending hours in dimly lit puja spaces and need your vision to be sharp.
Potassium for electrolyte balance. With approximately 400mg of potassium per serving, sweet potato chips help maintain electrolyte balance during fasting—important if you’re also reducing water intake or standing through long ceremonies.
Resistant starch for gut health. Sweet potatoes contain resistant starch that feeds beneficial gut bacteria during periods of calorie restriction, supporting digestive health when your eating patterns are disrupted.

The Drying Secret That Determines Crispness
Before we get into the step-by-step, let’s address the single most important factor in crispy sweet potato chips: thorough drying after soaking.
Here’s what happens: when you soak sweet potato slices in salted water (which you do for 15 minutes to extract moisture and prevent browning), the slices absorb some water on their surface. If you cook them immediately after soaking without drying, that surface moisture turns to steam in the air fryer. Steam creates humidity, and humidity is the enemy of crispness. The chips will come out chewy or leathery instead of crisp and golden.
The research notes state it directly: “Crispness depends on moisture escape.” Every drop of surface moisture you remove before cooking is one less barrier to achieving that perfect golden crunch.
Step-by-Step Instructions: Making Perfect Sweet Potato Chips
Step 1: Prepare and Slice the Sweet Potatoes
Wash 4 medium sweet potatoes (approximately 800g total) thoroughly to remove any dirt. You can peel them or leave the skin on—the skin adds fiber and color, and it crisps beautifully during cooking. The choice is yours.
Time: 10 minutes
Step 2: Soak in Salted Water
Prepare a large bowl of cold water and add a generous pinch of sendha namak. Add all the sliced sweet potatoes and let them soak for 15 minutes.
This soaking step serves two purposes: it draws out excess starch from the sweet potatoes (which prevents browning and improves crispness), and it seasons the chips from the inside out.
Time: 15 minutes soaking
Step 3: Drain and Dry Thoroughly (Critical Step)
Pat the slices dry thoroughly, then spread them out in a single layer on the cloth. Let them air-dry for 20 minutes. The goal is to remove as much surface moisture as possible. Turn them once halfway through if needed. They should feel dry to the touch—not damp, not wet—before you move to the next step.
Time: 20 minutes air-drying
Step 4: Preheat Air Fryer or Oven
While the slices are drying, preheat your air fryer to 200°C or your oven to 180°C (fan mode if available). The research notes state clearly: “Hot start sets crisp structure immediately.” Starting with proper heat is essential.
If using an oven, line a baking tray with parchment paper.
Time: 5 minutes
Step 5: Lightly Coat with Oil (Optional)
This step is optional. For the crispest results with minimal oil, lightly spray or brush the dried sweet potato slices with ghee or neutral oil. You can also skip this entirely and rely solely on the high heat of the air fryer to crisp the natural sugars in the sweet potato.
If you choose to use oil, a light mist is all you need—1 to 2 teaspoons total for the entire batch.
Time: 2 minutes
Step 6: Arrange in Single Layer
Arrange the sweet potato slices in the air fryer basket or on the prepared baking tray in a single layer with no overlapping. This is critical. Overlapping causes steaming rather than crisping. The chips need air circulation on all sides.
Time: 3 minutes
Step 7: Air-Fry Until Golden and Crispy
Air-fry at 200°C for 18 to 22 minutes, shaking the basket or rotating the tray at the 10-minute mark to ensure even cooking. Watch carefully during the final 5 minutes—sweet potatoes contain natural sugars that can go from golden to burnt quickly.
If using an oven at 180°C fan mode, the timing is similar but may extend to 22-25 minutes depending on your oven’s heat distribution.
Time: 18-22 minutes
Total Time: About 45 Minutes

Make-Ahead Strategy for Navratri
Prepare slices in advance and freeze them. On snacking days, air-fry directly from frozen with just 2 extra minutes of cooking time. This lets you have fresh-made chips without the daily prep work.
Why This Recipe Still Matters
In a fasting landscape increasingly focused on “healthy vrat options,” sweet potato chips occupy an interesting position. They’re genuinely nutritious—high fiber, exceptional vitamin A, good potassium—while also feeling like an indulgence. They’re crispy and satisfying in the way that most fasting snacks aren’t. And they store well, which makes them practical for the nine-day marathon of Navratri rather than just a single-day novelty.
The research notes that approximately 65 percent of households include root vegetables in fasting meals, and shakarkandi (sweet potato) sales reportedly surge by approximately 45 percent during Navratri periods. These aren’t just interesting statistics—they’re evidence of sweet potatoes earning their place as a fasting staple through genuine utility and appeal.
What makes sweet potato chips specifically valuable is that they address texture fatigue. After several days of soft fasting foods, crunch becomes psychologically important. The research quantifies this: crunch reportedly increases meal satisfaction by approximately 60 percent. That’s not trivial. That’s the difference between feeling content with your fasting meals and feeling deprived.
When you make sweet potato chips properly—when those thin slices emerge from the air fryer golden and crispy, when you season them with just the right amount of sendha namak, when you store them carefully and pull out a handful between meals for that satisfying crunch—you’re experiencing what happens when nutritional wisdom meets practical technique within the framework of fasting restrictions.
Why are my sweet potato chips chewy instead of crispy?
Chewiness almost always comes from insufficient drying before cooking or overcrowding during cooking.
Do I need to peel sweet potatoes before making chips?
No, the skin is completely edible and adds fiber, nutrients, and color to the chips. The skin crisps beautifully during air-frying.
Can I make these in a regular oven if I don’t have an air fryer?
Yes. Preheat your oven to 180°C with fan mode (convection) if available. Arrange the slices in a single layer on parchment-lined baking trays and bake for 22-25 minutes, flipping halfway through.
