FAQ

Can I prepare this dip ahead of time?

Yes. Combine all ingredients in your baking dish, cover with plastic wrap, and refrigerate up to 24 hours. Bake directly from the refrigerator, adding 5 minutes to cooking time if needed.

What if I don't have Dijon mustard?

Whole grain mustard or yellow mustard works well as substitutes. Use the same 2 teaspoons, though yellow mustard is milder. Spicy brown mustard intensifies the bite.

Can I freeze the leftover dip?

Freezing is not recommended due to mayonnaise breaking down during thawing. Store covered in the refrigerator up to 3 days and reheat gently before serving.
