Preheat the oven to 375°F (190°C). Remove 6 ounces cream cheese and 2 ounces mascarpone from the refrigerator and let soften at room temperature for about 20–30 minutes to make mixing easier.
In a medium bowl, combine the softened 6 ounces cream cheese and 2 ounces mascarpone with a pinch of salt, 1/4 teaspoon black pepper, and 1/8 teaspoon nutmeg. Mix with a spoon or rubber spatula until smooth and evenly combined.
Add 1 cup freshly grated parmesan cheese and 1/2 cup of the 3/4 cup sliced toasted almonds to the cheese mixture. Fold until the parmesan and almonds are evenly distributed.
Transfer the mixture to an ovenproof baking dish and spread/press it into an even layer.
Bake in the preheated oven for 25–30 minutes, until the dip is hot and the edges are set and lightly golden.
Remove the dish from the oven and sprinkle the remaining 1/4 cup sliced toasted almonds evenly over the top, pressing lightly so they adhere.
Let the dip cool for about 5 minutes, then serve warm with crackers and pita chips.
