Healthy Alfredo Sauce Recipe Variations
Low Sodium Alfredo Sauce
To make this Alfredo Sauce low sodium, cut the parmesan cheese by 1/2. You can add 1 teaspoon lemon zest to boost the flavor as well.
Gluten-Free Alfredo Sauce
To make this Alfredo Sauce gluten-free, swap out the flour for gluten-free flour. I like Bob’s Red Mill “One to One” gluten-free flour.
Low Fat Alfredo Sauce
This Alfredo Sauce is already pretty low in fat, but we can easily cut it down more by skipping the roux. Heat the almond milk and garlic clove in a sauce pot, once hot scoop out 1 cup of the almond milk and add it to a bowl. Add 2 tablespoons of cornstarch and mix well until you have a paste. Add this to the sauce and mix well. This will remove the butter and cut down the fat even more.
Vegan Alfredo Sauce
To make this a vegan Alfredo Sauce swap out the butter for vegan butter, and the parmesan for vegan parmesan cheese.
High Protein Alfredo Sauce
To boost the protein in this recipe add 1-2 scoops unflavored and unsweetened protein powder or collagen powder.
Low Carb Alfredo Sauce
This recipe is already low in carbs, to keep the carbs extra low serve this sauce over spaghetti squash, zoodles, or protein pasta. I like Banza chickpea pasta.

Refrigerate – Will hold in the fridge for up to 5 days.
