Keto alfredo sauce is a low-carb version of the traditional alfredo sauce commonly used in Italian cuisine.
Don’t worry, though—just because it’s a low-carb keto doesn’t mean it’s not tasty at all.
Rich and flavorful, keto alfredo sauce pairs well with a variety of keto-friendly dishes, such as zucchini noodles, spaghetti squash, grilled chicken, or keto pizza.

raw material
Keto alfredo sauce is made with simple ingredients like butter, heavy cream, garlic, and Parmesan cheese.
Because the ingredients are fairly basic, I recommend using fresh, high-quality ingredients to ensure a variety of flavors in your homemade keto alfredo sauce.
This is really important!
To make this creamy sauce you will need:
- parmesan cheese -Thickens and flavors sauces while adding saltiness and nuttiness. Fresh Parmesan that you shred yourself melts (and tastes) so much better than pre-grated.
- heavy cream – Delivers the creamy texture and richness that Alfredo sauce is known for, while being low in carbohydrates.
- unsalted butter – Use as a base for sauces to add richness and flavor. I recommend using grass fed butter for best results.
- garlic – Adds a fragrant aroma and subtle saltiness to sauces.
- salt and pepper – Enhances the flavor of the other ingredients in this keto alfredo sauce recipe and provides a balanced taste.

Making this creamy keto alfredo sauce is quick and easy. It can be done in a few easy steps.
Following these directions, you can create a deliciously creamy low-carb sauce that’s perfect to add to your favorite low-carb dishes.
First, melt the butter in a saucepan over medium heat. Then, add minced garlic, stirring constantly, and cook until fragrant.
Next, pour in the heavy cream and mix well. Reduce the heat to low and let the mixture simmer for 5-10 minutes or until it begins to thicken.
Finally, add grated Parmesan cheese, salt and black pepper. Stir until the cheese is completely melted and the sauce is smooth.
Taste and adjust seasoning as needed. Garnish with parsley and serve immediately on your favorite keto-friendly pasta or vegetable dish.
If you find that your keto alfredo sauce is too runny, one option is to simmer the sauce over low heat until it thickens and thickens to your desired consistency. You can also add more parmesan or cream cheese to the sauce. If your sauce is too thick, add a little more cream or water.
hint: You can also thicken the sauce by adding a low-carb thickener like xanthan gum, but be sure to add it gradually and stir well to avoid lumps.
Substitution
Several substitutions can be made for keto alfredo sauce to suit different dietary needs or preferences. Below you’ll find our recommended alternatives:
- parmesan cheese – Other hard cheeses such as Asiago, Pecorino Roman or Gruyère can be used in place of Parm.
- butter – Coconut oil, olive oil or ghee can be used instead of butter.
- dairy free – If you’re lactose intolerant or don’t eat dairy, you can substitute non-dairy alternatives like coconut cream and nutritional yeast for the heavy cream and Parmesan cheese. You may need to adjust other seasonings to balance the flavors.
Keep in mind that these substitutions may taste slightly different or change the texture of the low-carb alfredo sauce, so you may need to adjust other ingredients in the recipe to balance the flavors.
Variety
Want to mix up your Alfredo sauce? Here are five different flavors of keto alfredo sauce you can try:
- garlic and herbs – Add fresh or dried herbs such as basil, oregano, thyme or rosemary, and minced garlic to the sauce.
- Lemons and Capers – Add some fresh lemon juice and vinaigrette, and some salty capers. This adds a bright, rich flavor that pairs well with chicken or seafood.
- mushroom – Fry some sliced mushrooms in butter or ghee until they are soft and golden brown.
- Sun Dried Tomatoes and Spinach – Added some chopped sun-dried tomatoes and wilted spinach to the sauce. This will add a pop of color and flavor to the dish.
- Bacon and Cheddar – Fry some chopped bacon until crispy, then stir it into the sauce along with some shredded cheddar cheese. This will add a smoky and salty flavor to the dish.

equipment
Making keto alfredo sauce is a relatively simple process that doesn’t require any specialized equipment. However, having a few basic kitchen tools on hand can make the process easier and more efficient. Here’s some of the equipment you’ll need:
- pan or skillet – You will need a small to medium saucepan to cook the sauce. I opted to use a small cast iron skillet for my alfredo sauce. The smaller the pot, the longer it will take to cook. Alternatively, a pan that is too large can cause the sauce to burn.
- whisk or spoon – You will need a whisk or silicone/wooden spoon to stir the sauce.
- cheese grater – If you are using Parmesan or another hard cheese, you will need to shred the cheese with a grater.
- measuring cup and spoon – To ensure you add the right amount of ingredients to your sauce, you’ll need measuring cups and spoons.
Overall, the equipment needed to make keto alfredo sauce is minimal, and most home cooks already have everything they need in their kitchens.
storage
If you have leftover keto alfredo sauce or want to make a batch ahead of time, be sure to store it properly to ensure it stays fresh and delicious. Here are some tips on how to store Alfredo sauce:
- refrigerator – Store the sauce in an airtight container in the refrigerator for up to 5 days. Make sure the container is tightly sealed to prevent air from getting in and causing the sauce to spoil or dry out.
- refrigerator – You can also freeze keto alfredo sauce. Let the sauce cool completely, then transfer it to a freezer-safe container or zip-top bag. Freeze for up to 3 months. Thaw the sauce in the refrigerator before reheating.
- reheat – To reheat the sauce, heat gently on the stovetop or in the microwave. If the sauce is too thick after refrigerating or freezing, you can add a little heavy cream, water or broth to thin it to the desired consistency.
- separate – It is very common for Alfredo sauce to separate when refrigerated or frozen. If this happens, simply whisk the sauce vigorously or place it in a blender until it is smooth and creamy again.
By following these tips, you can store keto alfredo sauce for later.
top tips
Use a block of Parmesan cheese, shredded yourself. This will ensure that the cheese is melted and not grainy. Pre-shredded cheese contains additives that prevent it from melting properly.
FAQ
Store-bought or found alfredo sauces in restaurants are made with flours that are high in carbohydrates. However, keto alfredo sauce uses low-carb alternatives. Therefore, keto alfredo sauce is very low in carbohydrates.
Heavy cream is better for rich, creamy sauces. You can use whole milk for a thinner, less rich alfredo if desired, but whole milk has about twice the carbs of heavy cream.
If you find that your keto alfredo sauce is too runny, one option is to simmer the sauce over low heat until it thickens and thickens to your desired consistency. You can also add more parmesan or cream cheese to the sauce.
The good news is there are plenty of low-carb friendly ways to enjoy this decadent sauce. My favorite is using keto pasta, which usually ends up being zucchini noodles (learn how to make zoodles here). You can also try white wood sides.
Another great way to use this creamy sauce is with blackhead dough for pizza sauce. I also love using it as a dip for anything from bread to chicken.
