Pesto sauce is a great and very low carb way to add an Italian flair to your meal. You can pour it over some shrimp, chicken, zucchini noodles, Palmini noodles or add a little extra flavor to your vegetables. You can even freeze some to have on hand anytime you want!
Because this Keto pesto is a no-cook sauce, it relies heavily on the simple flavor combinations of only the freshest of ingredients, particularly the olive oil and parmesan cheese.
Toasting the pignoli (pine nuts) adds a wonderful nutty flavor as well.
Real Italian pesto has ever been easier. Blend it up in a matter of minutes and you’ll never go back to store bought again.

How to Make this Keto Pesto Recipe?
Add all the nuts, garlic, salt and pepper to the bowl of a food processor.
Pulse a few times, then add in the basil and lemon juice, pulse briefly.
With the food processor running, stream in the olive oil slowly until combined.
Add in the parmesan cheese and pulse just enough to combine.
Add a little more olive oil if needed to make it loose enough to pour over zoodles.
Note: Pine nuts are used in traditional pesto sauces, but I know they can be difficult to find in some areas. Walnuts are an excellent substitution in this case, and I definitely recommend toasting either nut you decide to use.
How Many Carbs in Pesto
This Keto Pesto recipe is extremely low carb. There is only one net carb per serving in this sauce. How’s that for low carb!?!
Store leftovers in the fridge in an airtight container.
Can You Freeze Pesto?
Pesto freezes very well. One convenient way to freeze it is to use an ice cube tray to freeze it into small portions. Once the cubes of pesto are frozen solid, dump them into a freezer bag and store for up to several months.
By using this method, you’ll have the perfect little portions for those times when you need a bit of pesto to top off a dish!
I used mine to make Grilled Chicken Pesto over Zoodles.

Is Pesto Keto?
Absolutely. In fact, if there was a number one place for a Keto condiment or sauce, it would have to be pesto. Just take a look at the ingredients…olive oil, basil, Parmesan. And pine nuts alone have almost perfect Keto macros with 21 grams of fat, 4 grams of protein and just 1 net carb.
You just can’t ask for a better source of fat in a sauce.
