Measure out and prepare all of the ingredients.

In a pan over medium heat, add the butter and minced garlic. Stir and cook until fragrant.

Stir in the heavy cream. Let this simmer for about 5 minutes. The mixture should become thick.

Reduce the heat to low. Add the parmesan cheese and stir. Whisk until all cheese is combined and everything is smooth.

Add in the salt and pepper and nutmeg. Stir until combined well.

Serve the alfredo sauce over chicken or cauliflower. Enjoy!
