Low Carb and Keto Homemade Alfredo Sauce with Basil Pesto in a jar.

Homemade Alfredo Sauce is very simple to make from scratch with just a few pantry ingredients. Rich, creamy, and packed with garlic, basil, and parmesan flavor, this is possibly the most flavorful Alfredo Sauce that you’ll ever have. 

HOMEMADE ALFREDO SAUCE WITH BASIL PESTO

Served over Carrot and Zucchini Noodles, keto pizza, or as a dipping sauce, our Alfredo Sauce recipe is my all-time favorite because… BASIL PESTO. It’s not much – I only use about a tablespoon – but it makes all the difference.

You can leave it out if you want, but please don’t. The basil pesto adds a certain zing to the entire sauce, and once you taste it, I don’t know if you’ll ever want to go without it.

HOW TO MAKE LOW CARB ALFREDO SAUCE

Like all great recipes, this one also starts out with:

butter √

garlic √

heavy cream √

parmesan cheese √

basil pesto √

salt & pepper √

  1. We first melt the butter in a large skillet and stir in the garlic. 
  2. Whisk in the heavy cream and cook for 5 minutes, until thickened.
  3. Next, whisk in the parmesan cheese, then the basil pesto. Cook over low heat until smooth and creamy.
  4. Add salt and pepper; taste for seasonings and adjust accordingly. If sauce is too thick for your liking, thin it out by adding a tablespoon of water or more cream. To thicken it, add a bit more parmesan cheese. 
  5. Pour over your favorite food and serve.

  • Store in an airtight container or jar with a lid. 
  • Keep in the fridge for up to 1 week. 
  • Please keep in mind that cream and cheese-based sauces do thicken as they stand; to thin out the sauce, whisk in a bit of cream or water to reach desired consistency. 

You can also freeze Alfredo Sauce:

  • Store in an airtight container or heavy-duty freezer bags and keep in the freezer for up to 3 months.
  • To prevent from curdling, stir well when reheating the frozen Alfredo Sauce.
