Additional Tips for Perfect Caramelized Onion Guacamole

Choosing the Right Avocados: Look for avocados that give slightly when gently squeezed. Too firm, and they’ll be hard to mash; too soft, and they might be overripe.
Caramelizing the Onions:
- Be patient! Cook the onions over low heat, stirring occasionally to avoid burning. This process can take 20–30 minutes but ensures deep, sweet flavor.
- Add a pinch of salt or a sprinkle of sugar while caramelizing to enhance their sweetness.
Balancing Flavors: Taste as you go! If the guacamole feels too sweet from the onions, add an extra squeeze of lime or a pinch of salt. If you love spice, don’t shy away from adding a dash of cayenne or chopped jalapeño.
Prevent Browning: To keep your guacamole vibrant green, press a piece of plastic wrap directly onto the surface of the guacamole to minimize air exposure, or serve it right away.
Customizing Texture: If you love a chunkier guacamole, dice the avocados instead of mashing them completely. For a smoother dip, use a fork or potato masher for a creamy consistency.
Caramelize onions ahead of time:
- Caramelize the onions in advance and store them in an airtight container in the fridge for up to a week. Warm them slightly before folding into the guacamole.
- Guacamole is best served fresh, but you can mix it a few hours ahead. Keep it in an airtight container with lime juice to prevent browning.
Creative Variations:
- Add crispy bacon bits for a smoky crunch.
- Mix in a dollop of Greek yogurt or sour cream for an extra creamy texture.
- Top with crumbled queso fresco or feta for added tang.
Serving Presentation: Garnish with a few reserved caramelized onions, a sprig of cilantro, or a sprinkle of chili flakes for a beautiful finishing touch.
