In a medium bowl, combine finely grated sharp cheddar cheese, creamy mayonnaise, chopped pecans, and sliced green onions. Blend until thoroughly mixed, creating a chunky texture.

Transfer the mixture into a 9x9-inch baking dish or pie plate and spread evenly, pressing gently.

Spoon raspberry preserves over the cheese mixture, spreading gently to cover entirely.

Cover with plastic wrap and chill in the refrigerator for at least 1 hour, or ideally overnight.

Remove from fridge and serve with buttery crackers for dipping.
