In a cold, large, ovenproof or cast-iron skillet, arrange bacon in a single layer. Cook over medium heat, stirring occasionally, until crispy, about 10 minutes.
Transfer bacon to a paper-towel-lined plate to drain. Reserve 2 Tbsp. cooked chopped bacon for serving.
In a serving bowl, mix white scallion parts, cream cheese, cheddar, almonds, mayonnaise, salt, and pepper until combined.
Top with green scallion parts and reserved 2 Tbsp. bacon. Serve cold or at room temperature with crackers alongside.
