Get ready to smother your zucchini noodles, chicken, or broccoli in this luscious, low-carb delight.

Why This Recipe Works

This keto Alfredo sauce recipe is a game-changer for several reasons:

• No Flour, No Problem: We ditch the traditional flour thickener and rely on heavy cream and cheese to create a luxuriously thick and creamy sauce.
• Simple Ingredients: You probably already have most of these ingredients in your keto-friendly pantry.
• Quick and Easy: This sauce comes together in under 15 minutes, making it perfect for busy weeknights.
• Customizable: Easily adapt the recipe to your taste by adding garlic, herbs, or spices.
• Authentic Flavor: The combination of Parmesan cheese, butter, and heavy cream delivers that classic Alfredo flavor you know and love.

Ingredients

• 4 tablespoons unsalted butter: Provides richness and flavor.
• 2 cloves garlic, minced: Adds a pungent and aromatic note. (Optional, but highly recommended!)
• 1 cup heavy cream: The base of our creamy sauce. Look for heavy cream with at least 36% milk fat.
• 1 cup grated Parmesan cheese: The star of the show! Use freshly grated Parmesan for the best flavor and melting properties. Avoid pre-shredded Parmesan, as it often contains cellulose that can prevent it from melting smoothly.
• 1/4 teaspoon xanthan gum: A keto-friendly thickening agent. A little goes a long way! This helps to prevent the sauce from separating.
• Salt and freshly ground black pepper to taste: Season to perfection!
• Optional additions: Nutmeg, red pepper flakes, fresh parsley, or other herbs.

Instructions

1. Melt the butter: In a medium saucepan over medium heat, melt the butter.
2. Sauté the garlic (optional): Add the minced garlic to the melted butter and sauté for about 30 seconds, or until fragrant. Be careful not to burn the garlic!
3. Add the heavy cream: Pour the heavy cream into the saucepan and bring to a simmer, stirring occasionally.
4. Whisk in the xanthan gum: In a small bowl, whisk together the xanthan gum with 1 tablespoon of the heavy cream. This will help prevent clumping. Slowly whisk the xanthan gum mixture into the simmering heavy cream.
5. Add the Parmesan cheese: Reduce the heat to low and gradually add the grated Parmesan cheese, stirring constantly until the cheese is melted and the sauce is smooth.
6. Season to taste: Season the sauce with salt and freshly ground black pepper to taste.
7. Adjust consistency (if needed): If the sauce is too thick, add a splash of heavy cream. If it’s too thin, simmer for a few more minutes, stirring frequently, until it thickens to your desired consistency.
8. Serve immediately: Pour the keto Alfredo sauce over your favorite keto-friendly pasta alternative, such as zucchini noodles, shirataki noodles, or palmini noodles. It’s also delicious with chicken, shrimp, broccoli, or cauliflower.

Tips for Success

• Use freshly grated Parmesan cheese: Pre-shredded Parmesan cheese often contains cellulose, which can prevent it from melting smoothly. Freshly grated Parmesan will give you the best flavor and texture.
• Don’t overcook the garlic: Burnt garlic will make the sauce bitter. Sauté it gently until fragrant.
• Add the xanthan gum gradually: Adding the xanthan gum all at once can cause the sauce to become lumpy. Whisk it in slowly and thoroughly.
• Keep the heat low: High heat can cause the sauce to separate. Cook the sauce over low heat and stir frequently.
• Adjust the seasoning to your taste: Don’t be afraid to experiment with different seasonings. Nutmeg, red pepper flakes, or fresh herbs can add a delicious twist to the classic Alfredo flavor.
• Prevent Graininess: To prevent the sauce from becoming grainy, avoid boiling it after adding the cheese. Keep the heat low and stir constantly. If graininess occurs, try adding a splash of lemon juice or white wine vinegar to help smooth it out.
• Consider Cheese Variation: While Parmesan is traditional, a blend of Parmesan and Pecorino Romano can add a sharper, saltier flavor. Experiment with different ratios to find your perfect blend.

Storage Instructions

Leftover keto Alfredo sauce can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm the sauce in a saucepan over low heat, stirring frequently. You may need to add a splash of heavy cream or water to thin it out. Avoid microwaving the sauce, as this can cause it to separate.

Freezing Alfredo sauce is not generally recommended, as it can change the texture and cause it to separate upon thawing. However, if you must freeze it, allow the sauce to cool completely before transferring it to a freezer-safe container. Thaw it in the refrigerator overnight and reheat gently as described above.

FAQ

Q: Can I use almond milk instead of heavy cream?

A: While you can use almond milk, the sauce will not be as thick and creamy. Heavy cream is essential for achieving the classic Alfredo texture. If you use almond milk, you may need to add more xanthan gum to thicken the sauce.

Q: Can I make this recipe without xanthan gum?

A: Yes, you can omit the xanthan gum. However, the sauce may be thinner and more prone to separation. If you omit the xanthan gum, be sure to cook the sauce over low heat and stir frequently.

Q: What can I serve with keto Alfredo sauce?

A: Keto Alfredo sauce is delicious with zucchini noodles, shirataki noodles, palmini noodles, chicken, shrimp, broccoli, cauliflower, or any other keto-friendly dish.

Q: Can I add protein powder to this sauce?

A: Adding protein powder is not recommended, as it can alter the texture and flavor of the sauce. If you want to add protein, consider serving the sauce with a protein-rich dish, such as grilled chicken or shrimp.

Q: Is this sauce vegetarian?

A: This recipe is vegetarian, as it does not contain any meat. However, Parmesan cheese is not vegan, as it is made from cow’s milk.
