Tips

Tip 1

Ensure cream cheese is fully softened before mixing to prevent lumps in the cheesecake filling. Room temperature ingredients blend more smoothly.

Tip 2

Cool the cheesecake gradually in the oven to prevent surface cracking. The slow temperature change helps maintain a smooth top.

Tip 3

Whisk custard constantly while cooking to prevent curdling. Remove from heat as soon as it coats the spoon to avoid overcooking.

Good to Know

Storage

Refrigerate covered for up to 5 days. Best texture when served within 3 days.

Make Ahead

FAQ

Can I use regular sugar instead of erythritol?

Yes, substitute 1:1 but this will no longer be keto-friendly and will significantly increase the carb content per serving.

How long does this cheesecake keep in the refrigerator?

Properly stored covered, it will keep for up to 5 days. The texture is best within the first 3 days of making.

Can I freeze this cheesecake?

Yes, wrap tightly and freeze for up to 2 months. Thaw overnight in refrigerator before serving for best texture.
