Onion samosa is a crisp and flaky tea-time snack made with thin samosa pattis and a spiced onion and poha filling. These small, triangle-shaped samosas are also known as Irani Samosa or Poha Samosa and are popular in Mumbai, Pune, Hyderabad and Irani cafés. The filling is quick to make and needs no cooking. You can fry, bake, or air-fry them for a light and crunchy snack that pairs perfectly with fried green chillies and hot chai.
Thaw store-bought samosa pattis or spring roll wrappers as per package instructions. Keep them covered with a damp napkin while working so they don’t dry out.
Prepare Flour Paste
In a small bowl, mix all-purpose flour with water to make a smooth, thick or medium-thick paste without lumps. The consistency should be like glue. Keep it covered while you shape the samosas.
Rinse Poha
Rinse thick poha in a strainer for about 15 to 20 seconds. Drain completely and set aside.
Make sure the poha is softened well, but not mushy or soggy.
Make Filling
In a bowl, combine finely chopped onions, ginger, coriander leaves, soaked poha, green chillies if using, and the ground spices, sugar, lemon juice, and salt.
Mix gently until everything is well combined.
Assemble, Fold & Shape
Place one samosa sheet vertically on a board or work surface. Lift the bottom corner and fold it diagonally to form a triangle. Flip upwards along the sheet, maintaining the triangular shape. Repeat two more folds to create a cone pocket.
Fill the cone about three-fourths full with the prepared onion mixture. Do not overfill or the samosa may tear while frying.
Apply the flour paste on the open edge and fold twice and lastly seal tightly. Press lightly to ensure all corners are closed.If you see any openings, dab a little extra paste and seal. Keep shaped samosas covered with a moist napkin while making the rest.
Fry Patti Samosa
Heat oil in a deep pan or kadai on medium heat. Once the oil is hot, reduce the heat to medium-low or low. Gently add samosas in batches and fry until golden and crisp on both sides. Remove on kitchen paper towels.
Fry Green Chillies
Slit green chillies and fry them in the same oil until you see light blisters on the skin. Remove and sprinkle some salt.
Bake Option
Preheat oven to 180 °C (350 °F) for 15 to 20 minutes. Brush oil on both sides of the samosas. Bake for about 15 minutes, turning once halfway through, until golden and crisp.
Serving & Storage
Serve Onion Samosa hot with fried and salted green chillies paired with chai.
Patti Samosa is best eaten fresh. You can refrigerate leftovers for 1 day and reheat in an oven or air fryer until crisp.
Notes
Always drain poha well before mixing, or the filling can turn soggy.
Finely chop onions so the sheets don’t tear while folding.
Seal the edges tightly with flour paste to prevent the filling from coming out.
Keep the samosa pattis covered with a damp cloth to avoid drying.
First heat oil until it becomes moderately hot. Lower the heat to medium-low or low heat and fry the onion samosa for even golden crispness.
For a healthier version, bake or air-fry patti samosa until evenly golden and crisp.
