We were so smitten with Olive Garden's most popular soup, we decided to crack the code so that we could make it ourselves on those days that we just can't get there.
For optimal flavor development, ensure the bacon and sausage are well-rendered and browned before removing them. The rendered fat is crucial for sautéing the aromatics. Dice the potatoes evenly for consistent cooking; they should be fork-tender, not mushy. Add the kale and cream only after the potatoes are cooked through, as overcooking kale can make it bitter and lose its vibrant color. The final splash of white wine vinegar brightens the soup and balances the richness, a key professional touch. Consider adding a pinch of dried oregano or thyme with the aromatics for a deeper Italian profile.
