Growing up, we ate out quite a bit.

One of my favorite places to go as a kid was the Olive Garden where Fettuccine Alfredo was my go to meal. I can still remember diving into a bowl. I would always ask for an extra side of Alfredo to dip my breadsticks in.

Because as much as I loved pasta, it was all about the delicious sauce.

Pasta and I have officially broken up, but I am still loving alfredo.

I think you are going to fall in love with this Keto Alfredo Sauce as much as I have. It has all the yumminess of you know and love.

Cream cheese thickens the sauce, eliminating the need for any other thickener.

Ingredients for Making Low Carb Alfredo Sauce

Butter: I recommend using unsalted butter so that you can adjust the seasonings to your liking.
Heavy Cream: If you are low carb and not keto, half and half works as well.
Broth: For best flavor, consider making your own using this Instant Pot Chicken Bone Broth recipe.
Cream Cheese: Make sure you use full fat. I typically pull it out of the refrigerator and let it come to room temperature before using, but this step is optional.
Seasonings: Garlic powder, Italian seasoning, salt and pepper round out the flavors for this delicious keto cream sauce. Adjust the amounts to your liking.
Parmesan: Use freshly grated or pre-grated from the refrigerator section.

Tips & Tricks

Make sure that you do not bring the sauce to a boil as this will cause the cheese to turn grainy. Keep it at a low simmer.
You will need to whisk this frequently - this keto white sauce isn’t a recipe you want to start and forget about.
Make sure that you use fresh Parmesan cheese and not canned.

VARIATIONS FOR THIS RECIPE

Add an extra kick with ¼ teaspoon cayenne pepper.
You can use Asiago cheese in place of the Parmesan.

Serving Suggestions

One of my favorite ways to enjoy it is with Keto Chicken Alfredo or in this Keto Alfredo Chicken Bake.

Both are crazy good and surprisingly easy meals. It is also great over broccoli, spaghetti squash or meatballs or even just drizzled on a steak. Dinner bliss!
