This classic Italian sauce is creamy and rich. Traditionally the ingredients are heavy cream, butter, Parmesan, salt and pepper. There are many other variations around, often including garlic, egg yolks, flour, bacon, and more! Alfredo is one of the few sauces that I'll buy pre-made in jars, because the carb count is much lower than in most other sauces. I'll order it in restaurants too as I know I'm going to be full by the end of the meal,
But when I stopped to look at how it is made, I was struck by that list of traditional ingredients, which are ALL low carb (and quite high in fat too, I should note)! With a bit of research and testing, I arrived at this recipe which is AWESOME and actually very easy to make. I serve it with meat, fish, and veggies – it's very versatile. You are seriously going to love it!

How to Make Low Carb Alfredo Sauce
To start making the sauce, melt some butter in a saucepan. Add heavy cream, and stir well.
Add grated Parmesan cheese, a quarter cup at a time, whisking well between each addition.
Taste for seasoning and add salt and black or white pepper, as required. And done! Less than 50 words in those instructions and the result is a rich, decadent, creamy sauce.

You could even add a little chopped parsley for garnish – it depends what you're using it for!!
This low carb alfredo sauce is so smooth, thick, and comforting. It's like a hug in a sauce!
This sauce can be made ahead of time and reheated if necessary. It may separate, but whisking will rescue it! This keto Alfredo sauce works really well with chicken, broccoli, cauliflower and many other dishes. I love combining it with spaghetti squash!
