Low and Slow: Keep the heat low while cooking to prevent the cream from scorching or curdling.
Crushed Garlic or Powder Garlic: If you’re out of fresh garlic, garlic powder works in a pinch. Just start with a small amount and adjust to taste.
Spicy Alfredo Pasta: This sauce clings beautifully to fettuccine, penne, or any pasta with ridges to capture all that creamy goodness.
Gluten-Free Alfredo Sauce: This sauce is 100% gluten-free although check the ingredients on the label of your hot sauce to make sure it is also gluten-free and use gluten-free pasta.
