For the best homemade tortilla chips, fry them. The recipe includes details for fried and baked tortilla chips. The baked chips are excellent, but they will not be as light or crispy as the traditionally fried chips. The recipe calls for 10 corn tortillas, but you can increase or decrease this amount based on how many chips you would like to make.
For the best flavor, look for tortillas made using nixtamalized corn. Nixtamal is dried corn cooked and soaked in water with calcium hydroxide (slaked lime or cal). Not all store-bought tortillas use this method, which is why the flavor of corn tortillas can vary. Look for “nixtamal” or “nixtamalized” on the package. You can also look at the list of ingredients (it should be short and have the words “lime” or “cal.”)
10 corn tortillas or use more for more chips, stale or dried out tortillas are best
3/4 to 1 cup neutral, high-heat cooking oil like avocado oil, safflower oil, peanut oil, or vegetable oil
Sea salt to taste
Cut each tortilla into 6 triangles.
Line a plate with paper towels or a clean dishcloth, and set aside.
Add the oil to a wide, high-sided pot or cast iron pan until it’s about 1/2 inch deep. Heat on medium-high until the oil reaches 350°F (177°C).
Add a single layer of tortilla triangles to the hot oil. Use a slotted spoon or tongs to push them down into the oil.
Cook until the chips are crispy and golden brown, about 2 minutes.
Transfer them to the prepared plate and sprinkle lightly with salt. Repeat with the remaining tortillas.
Preheat the oven to 375°F (190°C). Line two baking sheets with parchment paper or use a silicone baking mat.
Spray or lightly brush the tortillas on both sides with oil.
Cut each tortilla into six triangles and arrange them in one layer on the baking sheets.
Bake until the chips are crisp and golden brown, 10 to 20 minutes. Check the chips often, and if some are browning quicker than others, rotate the baking sheets to encourage even baking.
Lightly season each chip with salt and then serve.
