Combine butter, mayonnaise, cheese, olives and green onions in a mixing bowl
Stir together until thoroughly combined. Mixture can be refrigerated at this point and used within 2-3 days
Spread mixture onto French bread that has been sliced lengthwise
Bake at 325ºF for 20-25 minutes or until cheese is melted and edges of bread are browning
Notes
Choose the right bread - A crusty French loaf or Italian bread works best—it holds up well to the rich topping without getting soggy.
Mix up the olives - Use a combination of black and green olives for the best flavor. Kalamata adds a tangy bite, while green olives bring in saltiness.
Don’t skip the fresh herbs - A sprinkle of fresh parsley or basil adds color and freshness to balance the richness.
Use real cheese -Sharp cheddar, mozzarella, Monterey Jack, or even a bit of parmesan will give great flavor. Shredding your own cheese melts better than pre-shredded.
Soften the butter -Make sure your butter is softened (not melted) before mixing it with the olives, cheese, and mayo—it spreads more easily and evenly.
