Begin by ensuring the cream cheese is softened for easy mixing. If it's too firm, cut it into smaller chunks and microwave in 10-second increments until soft.

In a large mixing bowl, combine the softened cream cheese and mayonnaise. Using an electric mixer or a sturdy spatula, beat these two ingredients together for about 2 minutes until smooth.

Add the dry ranch dressing mix and dry Italian dressing mix to the bowl. Continue mixing for 1-2 minutes until thoroughly incorporated.

Stir in the undrained chopped green chilies until evenly mixed. Use a spatula to fold the mixture gently.

Fold in the shredded cheddar cheese and Monterey Jack cheese until evenly distributed.

Add the chopped green onions and pickled jalapeños, stirring well and adjusting the jalapeño quantity based on desired spice level.

Transfer your dip to an airtight container or cover the bowl and refrigerate for at least 2 hours, or ideally overnight.

Before serving, give it a good stir to bring ingredients back together and transfer to a serving bowl.

Serve with your favorite crackers, such as saltines, tortilla chips, or fresh veggie sticks.

Optionally garnish with extra cheese, chopped green onions, or additional jalapeños.
