    The Best Keto Alfredo Sauce

    If you're looking for the best keto alfredo sauce recipe to use during your next keto pasta night, this is it! It's rich, velvety, and buttery all at the same time. And this homemade keto alfredo sauce delivers all of that deliciousness without the added "junk" ingredients you'll find in the store-bought kind. 

    Having said that, this creamy keto alfredo sauce is the perfect sauce for more than just pasta. It can complement a variety of other dishes too.

    I mean, you can serve it over vegetables, chicken, and shrimp. And it's so smooth and tasty that literally anything you decide to put on it is instantly upgraded with some added savory deliciousness. 

    That said, my favorite way to use this sauce is to make some keto chicken alfredo with zoodles with it! The whole thing comes together in literally just 15 minutes, and I swear it's one of the best quick and easy keto dinners you can make!

    Now, I'm sure all of this food talk is getting you hungry, so let's jump into the recipe!

    Ingredients

    Ok, the keto alfredo sauce ingredients are all simple keto friendly ingredients.

    And there's a good chance you have all of these ingredients at home already.

    Here's what you'll need to make low carb alfredo sauce:

    • 1 Tbsp. Butter
    • 2 Cloves Garlic, Minced
    • 1 Cup Heavy Cream
    • ½ Cup Cream Cheese
    • ½ Cup Grated Parmesan Cheese
    • ⅓ Tsp. Oregano
    • Black Pepper to Taste
    • Salt to Taste

    Isn't it crazy how just a handful of ingredients can make such a flavorful sauce?!

    By the way, if you want to make a bigger batch of this keto alfredo sauce, all you have to do is double the amount of each ingredient. You'll then have sauce for a large family dinner or even an entire week's worth of meal prep.

    Also, if you have some heavy cream left over, put it to good use and make this Buffalo chicken soup with it.

    Grate Your Own Cheese

    Now for this low carb alfredo sauce, the parmesan cheese will give the sauce that oh so cheesy flavor. 

    I recommend buying a block of parmesan cheese and grating it yourself, rather than getting the pre-grated kind. 

    Pre-grated or shredded cheeses usually have added starches in them that keeps the cheese from sticking together. And these starches will add unwanted carbs to the cheese in the process.

    So, if you shred it yourself with a cheese grater, you'll keep the carbs as low as possible in the sauce.

    Plus, if you end up with extra parmesan cheese, you can use it to make these low carb cheese crackers!

    How to Make the Best Keto Alfredo Sauce

    Alright, now that we've talked about the ingredients you'll need for this alfredo sauce, let's talk about how to make it.

    Two simple steps are all you'll need to follow for this keto alfredo sauce recipe.

    So, whether you're an expert or a beginner in the kitchen, I promise your keto alfredo sauce will turn out delicious. 

    Now let's get into the steps and make the sauce!

    STEP 1: PREP WORK

    So to start, you'll want to grate your parmesan cheese and mince two cloves of fresh garlic.

    STEP 2: STOVE-TOP INSTRUCTIONS

    The next step is to melt the butter and sauté the garlic in a saucepan over medium heat. This will take about 30 seconds.

    Then, pour in the heavy cream and cream cheese and bring them to a boil while continually stirring. 

    Continue this for about 1 minute, then add your grated parmesan cheese, oregano, black pepper, and sea salt.

    Once the ingredients are in the saucepan, stir everything together until the sauce is well-combined.

    After this, remove the saucepan from the heat. 

    And voilà! Your keto alfredo sauce is ready to go!

    Ways to Use Keto Alfredo Sauce

    I mentioned earlier a few traditional ways you can use this creamy keto alfredo sauce recipe, but there are many other ways to have it as well!

    You can use it as a dipping sauce for these keto mozzarella sticks or keto crackers.

    You could use it in place of marinara sauce for this 10-minute keto pizza.

    Or, you could even meal prep this instant pot shredded chicken and use it as a sauce for that as well.

    Serving It With Keto Pasta 

    Of course, one of the best ways - if not the best way - to enjoy this keto alfredo sauce is over pasta. I mean, it is a pasta sauce after all.  

    So, I highly recommend pairing it with some zoodles or this keto pasta made from hearts of palm.

    Personally, I love using zoodles. I love how the freshness of the zoodles balances out the richness of the alfredo sauce.

    And besides being fun to say, zoodles are super easy to make - I'll actually be talking more about that in my upcoming keto chicken alfredo recipe, so definitely stay tuned for that!

    How to Store Keto Alfredo Sauce

    So, this recipe makes 14 servings of keto sauce -which is perfect for a big dinner with family and friends, meal prep, or to have on hand to use for a variety of different keto meals. 

    And one more thing to love about this keto alfredo sauce is that it can be stored and reheated anytime!

    You can keep the sauce in an airtight container in the fridge for up to a week. Or, you can also keep it in the freezer for up to 3 months. 

    How To Reheat Keto Alfredo Sauce

    Once you're ready to enjoy this keto alfredo sauce recipe again, all you have to do to heat it back up is put it in the microwave or a saucepan over low heat until it reaches the desired temperature.

    Now, take note that the sauce gets a little thicker after being stored. To thin it out, stir in a little more heavy cream - or even almond milk - as needed.

    Wrapping It Up

    That is how to make keto alfredo sauce! I mean, this easy keto alfredo sauce is high in fat and low in carbs & protein. It doesn't get much better than that.

    This keto recipe is spot on to what you would get from an authentic Italian restaurant. 

    I can honestly say that this is one of the best sauce recipes I've ever made.

    Oh, and if you're looking for some keto friendly pasta to put this alfredo sauce on, I've got a super tasty recipe on the blog that you should totally check out next.

    Anyway, I hope you enjoy this rich, creamy, and easy keto alfredo sauce recipe. I'd love to hear how you use it in the comments below!

      I made this for dinner tonight for my family. I didn’t have any oregano so I left that out. I doubled the recipe and added chicken and put it over gluten free pasta for the rest of my family. I just had some over chicken. So easy to make and everyone liked it including my picky eater!
