⭐ Greek Yogurt (Best Nut-Free Option)
1:1 (1/4 cup Greek yogurt per 1/4 cup sour cream)Greek yogurt has a similar protein and fat content to sour cream, which helps maintain the creamy texture and slight tanginess essential for pasta sauces. The lactic acid in Greek yogurt mimics the sour flavor of sour cream, preserving the intended taste balance.
When incorporating Greek yogurt into hot pasta, temper it by mixing with a small amount of warm sauce before adding to prevent curdling. Stir gently and avoid boiling after adding.
The final dish will have a slightly thicker texture and a fresher tang compared to sour cream, enhancing the pasta sauce without overpowering it.
