Step 1: Preheat and Prepare
Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or a silicone baking mat. This step is absolutely crucial – without it, your chips will stick terribly and be impossible to remove. Set aside another piece of parchment paper for rolling.

Step 2: Melt the Cheese
Place the shredded mozzarella cheese in a large microwave-safe bowl. Microwave on high for 1 minute, then stir. Continue microwaving in 30-second intervals, stirring between each, until the cheese is completely melted and smooth. This usually takes 1.5 to 2 minutes total. The cheese should be fluid and stretchy. Alternatively, you can melt the cheese in a double boiler on the stovetop if you prefer.

Step 3: Make the Dough
Working quickly while the cheese is still hot and pliable, add the almond flour, egg (if using), salt, garlic powder, onion powder, cumin, chili powder, cayenne (if using), and lime zest to the melted cheese. Stir vigorously with a spoon or spatula until a thick dough forms. The mixture will be sticky at first but will come together as you mix. If the cheese starts to cool and becomes difficult to work with, microwave for another 10-15 seconds to soften it. Once combined, use your hands to knead the dough a few times in the bowl until it’s smooth and uniform. The dough should be slightly warm, pliable, and not too sticky.

Step 4: Roll Out the Dough
Place the dough ball on your prepared parchment paper-lined baking sheet. Place another piece of parchment paper on top of the dough. Using a rolling pin, roll the dough out as thin as possible – ideally about ⅛ inch thick or even thinner. The thinner you roll it, the crispier your chips will be! Roll evenly to ensure uniform baking. If the dough is sticking to the rolling pin or parchment, it’s too warm – let it cool for a minute or two. Aim for a large rectangle or square shape to minimize waste.

Step 5: Cut into Triangles
Remove the top piece of parchment paper. Using a pizza cutter or sharp knife, cut the dough into chip-sized triangles. Traditional tortilla chip size is about 2-3 inches per side. You can cut straight lines to make squares first, then cut diagonally to create triangles, or cut into any shape you prefer! Don’t separate the pieces yet – leave them touching for now. This makes them easier to handle before baking.

Step 6: Pre-Bake (Optional but Recommended)
For extra crispy chips, pre-bake the entire sheet of connected chips for 5 minutes. Remove from the oven and gently separate the pieces, spreading them apart slightly so they’re no longer touching. This allows air to circulate around each chip.

Step 7: Bake Until Crispy
Return to the oven and bake for 6-8 more minutes (or 10-12 minutes total if you skipped the pre-bake step), watching carefully. The chips are done when they’re golden brown around the edges and firm to the touch. Some darker spots are fine and add flavor, but watch carefully in the final minutes to prevent burning. They’ll continue to crisp up as they cool, so don’t overbake. Remove any chips that are done early to prevent burning while others finish.

Step 8: Cool Completely
Transfer the chips to a wire cooling rack (or leave on the baking sheet) and let them cool for at least 5-10 minutes. This cooling period is essential – the chips will be soft when hot but will become crispy and crunchy as they cool. Resist the urge to eat them immediately! Once completely cool, they’ll have that perfect tortilla chip snap.
