01 - Preheat the oven to 375°F. Line two baking sheets with parchment paper.
02 - Cut each corn tortilla into 6 wedges to create chips. Arrange the wedges in a single layer on the prepared baking sheets.
03 - Lightly brush both sides of the tortilla wedges with vegetable oil. Sprinkle with salt and smoked paprika, if desired. Bake for 12–15 minutes, flipping the chips halfway through, until they are golden and crisp. Remove from the oven and allow to cool.
04 - While the chips bake, halve and pit the avocados. Scoop the flesh into a medium-sized bowl and mash with a fork until mostly smooth, leaving some texture with small chunks.
05 - Add the finely diced red onion, seeded and diced tomato, finely chopped jalapeño, fresh cilantro, lime juice, salt, pepper, and minced garlic (if using) to the bowl with the mashed avocado. Stir gently to combine all ingredients thoroughly.
06 - Taste the guacamole and adjust the seasoning with additional salt, lime juice, or jalapeño to suit your preference.
07 - Transfer the freshly prepared guacamole to a serving bowl. Serve immediately with the homemade, crispy tortilla chips.
