HOMEMADE ALFREDO SAUCE WITH BASIL PESTO
Served over keto pizza, steak pasta, 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 √
- We first melt the butter in a large skillet and stir in the garlic.
- Whisk in the heavy cream and cook for 5 minutes, until thickened.
- Next, whisk in the parmesan cheese, then the basil pesto. Cook over low heat until smooth and creamy.
- 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.
- Pour over your favorite food and serve.
HOW TO STORE HOMEMADE ALFREDO SAUCE
- Let sauce cool down completely.
- 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.
This sauce is quick and easy to make, taking a total time of 10 minutes and made with ingredients you already have on hand.
If you couldn’t tell by now, I am a all about homemade sauces:
and so on…
Basically, I buy sauces from the store only if my time is limited. Homemade just tastes better, but most importantly, you have full control over the ingredients.
ENJOY!
