How to Store or Freeze This Sauce
- Allow the Keto Alfredo Sauce to cool completely before storing. This prevents condensation, which can make the sauce watery.
- Transfer the sauce to an airtight container. Glass jars or BPA-free plastic containers work best to maintain freshness.
- Label the container with the date to keep track of its shelf life.
- Store the sauce in the refrigerator for up to 5 days. The heavy cream and butter help preserve its rich texture.
- For longer storage, consider freezing. Pour the cooled sauce into a freezer-safe container, leaving some space at the top for expansion.
- Alternatively, use ice cube trays to freeze individual portions. Once frozen, transfer the cubes to a ziplock bag for easy portion control.
- When ready to use, thaw the sauce in the refrigerator overnight. Avoid microwaving directly from frozen to prevent separation.
- Reheat the sauce gently on the stovetop over low heat, stirring frequently to maintain its creamy consistency.
- If the sauce appears too thick after reheating, add a splash of heavy cream or chicken broth to achieve the desired consistency.
- Pair the reheated sauce with freshly cooked keto-friendly pasta or vegetables for a quick and delicious meal.
How to Reheat Leftovers
Stovetop Method: Place the leftover Keto Alfredo Sauce in a saucepan over low heat. Stir continuously to prevent the sauce from separating. If the sauce appears too thick, add a splash of heavy cream or chicken broth to reach the desired consistency.
Microwave Method: Transfer the sauce to a microwave-safe bowl. Cover it with a microwave-safe lid or plastic wrap with a small vent. Heat on medium power in 30-second intervals, stirring in between, until the sauce is heated through. If the sauce is too thick, mix in a bit of heavy cream or water.
Double Boiler Method: Fill a pot with a couple of inches of water and bring it to a simmer. Place the leftover Keto Alfredo Sauce in a heatproof bowl and set it over the simmering water, ensuring the bottom of the bowl doesn't touch the water. Stir occasionally until the sauce is warmed through and smooth.
Oven Method: Preheat your oven to 300°F (150°C). Place the sauce in an oven-safe dish and cover it with aluminum foil. Heat for about 15-20 minutes, stirring halfway through. If the sauce is too thick, add a bit of heavy cream or broth and stir well before serving.

How to Save Time on This Recipe
