Half-and-Half (Best Option)
1 cup per 1 cup whole milkHalf-and-half contains about 10-12% fat, which is closer to whole milk's 3.5-4% fat than other dairy substitutes. This fat content helps in browning and caramelizing the vegetables during roasting, enhancing flavor and texture.
When using half-and-half, ensure even coating of the vegetables to prevent pooling and sogginess. It’s best added before roasting to allow the fat to aid in Maillard reactions.
The final dish will have a slightly richer mouthfeel compared to whole milk but will maintain the intended moisture and flavor profile without overwhelming the vegetables.
