Make ahead:You can prep the goat cheese log entirely in advance, wrap it tightly in plastic and refrigerate for up to 3 days. The pecan coating will not be as crunchy but still delicious. For a crunchier coating, you can prep the cheese log all in advance except for the pecan coating, then when ready to serve, let the cheese log sit for 15 minutes or so at room temperature to soften then roll in pecans.
Herbs: You can mix up the herbs with your favorites!
Goat cheese substitute:Yes, you can use cream cheese, just like a cheeseball. I think cream cheese with some finely, freshly grated Parmesan would be tasty.
Nut substitute:Nothing stays quite as crunchy as nuts, so I recommend not substituting unless you need to for nut allergy reasons. If that’s the case, you can try panko toasted with a little butter like I do in this cheeseball: https://carlsbadcravings.com/bruschetta-cheese-ball/ or toasted sesame seeds, crushed crackers, crushed pretzels or crushed potato chips – or a combo. I recommend adding these coating options last minute so the stay crunchy. You can also add dried cranberries, cherries, etc.
