The Proven Trick to Keep Guacamole Fresh and Green All Day

Homemade guacamole lovers know the truth: once you've mastered it, store-bought versions pale in comparison in flavor and freshness. It's simple to whip up—mash ripe avocados with a fork, then mix in your favorite spices (Old El Paso's blend is a standout). For the ultimate fresh version, blend avocados with lemon juice, garlic, onion, tomato, and a dash of Tabasco. The catch? It quickly turns brown from oxidation, ruining the vibrant green appeal.

Use a Cooking Spray to Preserve That Perfect Green

Food experts at PureWow share a game-changing tip: lightly mist fresh guacamole (or cut avocado halves) with a neutral cooking spray like canola oil nonstick spray. This simple barrier keeps it vividly green for up to 24 hours—ideal for prepping ahead or saving half an avocado without waste. While cooking sprays aren't staples in French supermarkets, you can grab authentic PAM spray from My American Market for just €6.29.
