Are There A Lot Of Carbs In Alfredo Sauce?

Traditional Alfredo sauce is generally still considered low carb, but is not keto-friendly, as it uses flour to thicken the sauce.

With this Keto Alfredo sauce, cream cheese and parmesan cheese are used to thicken the cream sauce to perfectly coat anything you choose to serve it with.

What Can I Use Instead Of Cream In Alfredo Sauce?

If you are out of cream and are trying to avoid a last-minute trip to the grocery store, you do have some options. The most readily available in most kitchens are milk and almond milk.

Neither one of the options are the lowest in carbs, so make sure you adjust the nutritional information when you are calculating your daily macros.

Ingredients You'll Need

Butter- I prefer unsalted butter, as the parmesan cheese can be quite salty.
Cream Cheese- Is the primary thickener for this alfredo sauce. It adds a little extra zing to the flavor as well.
Heavy Cream- Makes the cream sauce extra creamy and perfectly pourable.
Parmesan Cheese- Provides a saltiness to the keto alfredo sauce and helps to thicken it.
Salt- Just a touch to taste.
Pepper- Brings out the natural flavors of the parmesan cheese and nutmeg.
Garlic- Diced finely so it doesn't overpower each bite.
Nutmeg- Gives a warm, nutty flavor to your homemade alfredo sauce.

How To Make Keto Alfredo Sauce

All you need is a skillet, a burner, and a few minutes to make an absolutely delectable keto alfredo sauce. Just follow the instructions below for a fail-proof cream sauce every time:

Place a skillet on your stove top and turn your burner on to medium low heat. Add the butter and allow it to melt. Pour in minced garlic and allow it to cook for approximately 1 minute.
Once the butter has melted, add the heavy cream and turn the temperature down to low. Do not allow the cream to boil This can cause it to separate.
Once the heavy cream and butter mixture is hot (but not boiling), cube the cream cheese and add it to the skillet. Whisk repeatedly until the cream cheese is incorporated into the heavy cream.
Add salt, pepper, and nutmeg and stir well.
Remove the skillet from the heat and add parmesan cheese. The residual heat from the sauce base will help the parmesan melt. Stir until well incorporated and serve.

Variations

Omit the cream cheese. The cream cheese in this recipe is used to further thicken the cream sauce. If you're not a fan of the flavor of cream cheese or are trying to reduce the calories per serving, it can be omitted. The addition of heavy cream and parmesan cheese does thicken the sauce so it is not watery, but it may not coat the back of a spoon the same as it would with the cream cheese included.
Spice it up. If you like things spicy, turn this into a Cajun Alfredo sauce. Sprinkle in a tablespoon or two of Cajun Spice Mix to jazz up the flavor of your next Alfredo dish.
Double the recipe. I'm not joking when I say this recipe is absolutely addictive. It can be used in a variety of dishes as a flavor booster or served alongside some of your favorite meals as a way to increase your daily fat macros to keep hunger at bay.

Serving Suggestions

Serve over veggies. Steam some zucchini noodles, cauliflower, broccoli, or even spaghetti squash, and drizzle a little bit of this keto alfredo sauce over the top.
Use as a dipping sauce. Use keto bread, keto chicken tenders, or even cauliflower breadsticks to dip in this low carb alfredo sauce.
Make a creamy casserole. Use this cream sauce as a low carb substitute for the bechamel sauce. Pour it into a variety of casseroles such as Keto Broccoli Chicken Casserole or Chicken Cordon Bleu Casserole to make them extra creamy.

How Long Does It Last?

Whether you happen to have leftovers or simply decided to double the recipe to enjoy with another meal, you can expect a bite that is just as tasty the second time.

For the best results, store the keto alfredo sauce in an airtight container in the refrigerator for up to four days.
