1/2 cup sour cream – This is where the creaminess kicks in!
1/2 cup mayonnaise – Trust me, it makes the sauce ultra-rich and luscious.
1 1/2 cups shredded cheddar cheese (divided) – Because gooey, melty cheddar is a must!
1/2 cup shredded mozzarella cheese – For that irresistible stretchiness.
2 eggs, lightly beaten – Helps hold everything together while adding a little fluffiness.
1/4 cup heavy cream – Makes it extra silky and indulgent.
1 tbsp mustard (Dijon or yellow) – A tiny zing that ties it all together.
1 tbsp Worcestershire sauce – Adds a deep, umami-packed flavor boost. (check for gluten-free)
1/2 cup cooked and crumbled bacon (optional but highly encouraged!) – Because bacon makes EVERYTHING better, period.
