Select avocados that yield slightly to gentle pressure but aren't mushy—they should hold their shape during baking without becoming too soft or separating from the skin.

Sprinkle kosher salt on your baking sheet under the avocado halves to prevent them from rolling or tipping over during baking, ensuring the eggs cook evenly.

Use a preheated baking sheet at 400°F for 2-3 minutes before placing avocados on it—this ensures the eggs begin cooking immediately for better texture and consistent doneness.

Dust garlic powder directly into the avocado well before cracking the egg, then add more around the egg white for complex flavor distribution that won't taste one-dimensional.

Add parmesan cheese in the last 2-3 minutes of baking so it melts and lightly browns rather than burning, creating a golden crust while keeping the cheese flavorful and not bitter.
