Substitute for Milk in Cream Soup: Rich and Dairy-Free
When making cream soup, the best substitute for milk is Oat Milk + Butter. Oat milk's natural starchiness gives soup a creamy body similar to dairy milk. Adding butter boosts the fat content and richness. It is heat-stable and does not curdle when simmered. Milk adds creaminess and body to cream-based soups like cream of mushroom, broccoli cheddar, and potato soup. It provides a smooth, rich base. The substitute needs body, creaminess, and heat stability.
