Is Alfredo Sauce Keto?
Many store bought Alfredo sauces are not keto-friendly, as they contain sugar and starches, and have up to 5 grams of carbs per serving. Jarred Alfredo sauces are highly processed and should be avoided on healthy low-carb diets.
However, homemade sauces do not require these things. Alfredo sauce is a thickened cream sauce, flavored with garlic, Italian seasoning, and parmesan cheese. In moderation, it’s a healthy addition to a keto or low carb diet.
What You’ll Need
- Butter (pastured or grass-fed has the best nutrient profile!)
- Garlic (fresh is best! It’s a prominent flavor in Alfredo sauce, so buying bulbs of fresh garlic and freshly chopping it will give you the best flavor.)
- Heavy Whipping Cream (I buy pastured or grass-fed, which makes this a more nutritious sauce).
- Parmesan Cheese (you can buy grated cheese, or a block and grate it yourself.)
- Sea Salt & Pepper
- Italian Seasoning
- Nutmeg (optional, use if you enjoy it!)
- Parsley (an optional garnish for your Alfredo pasta dishes! We love the fresh touch it adds to the rich sauce.)
How to Make a Low Carb Alfredo Sauce
Step 1: Into a skillet, add butter and garlic and saute over medium heat until the garlic is fragrant, about 5 minutes.
Step 2: Into the skillet, pour the heavy whipping cream. Stir the heavy whipping cream as it heats up, for about another 5 minutes.
Step 3: Add the parmesan cheese into the hot heavy whipping cream, and stir constantly until well incorporated. The sauce needs to bubble for about 5-7 minutes at a LOW SIMMER (not boil) to melt the cheese. NOTE: If your sauce isn’t “creamy”, or the cheese does not seem melted, you have not simmered it long enough or did not heat the cream prior to adding the cheese.
Step 4: Add and adjust the seasonings to taste, and then remove the creamy sauce from heat once it reaches the desired consistency. Use while hot. The sauce will thicken and a film will form over the top as it cools.
FAQs for the Best Sauce!
Why is my Alfredo Sauce too thin?
If your sauce seems thin, it hasn’t simmered long enough. Allow it more time, and as the water in the cream evaporates and the cheese fully melts, the sauce continues to thicken. Also be sure to fully heat the cream prior to adding the parmesan cheese.
What if my Alfredo sauce becomes too thick?
If your sauce thickens beyond your preference, thin it with additional heavy whipping cream, and then season it with more salt and pepper if necessary.
What type of cream is used for Alfredo Sauce?
Alfredo sauce is made with heavy whipping cream. Using half and half will increase the carb count, and also make it more difficult to form a thick sauce without using a starch.
