Gather all your ingredients. Ensure your cream cheese is softened for easy mixing.
In a large mixing bowl, combine the softened cream cheese, mayonnaise, and sour cream (or Greek yogurt). Use a mixer to blend until smooth and creamy.
Sprinkle in the garlic powder, onion powder, paprika, dried oregano, salt, and pepper. Mix until evenly incorporated.
Add the freshly shredded cheddar cheese to the mixture. Stir gently with a spatula to maintain a chunky texture.
Carefully fold in the drained jarred pimentos and chopped pickled jalapeños. Adjust the amount of jalapeños based on your heat preference.
Transfer the dip to your serving dish and refrigerate for at least 30 minutes to allow the flavors to meld. Garnish with chopped green onions before serving, if desired.
