Easy Spinach Pesto Recipe (2024)

FAQs

Why is my spinach pesto bitter? ›

The most common reason for pesto tasting bitter is that the olive oil is past its best and has started to turn rancid.

Add a pinch of salt if the basil tastes too bitter or the pesto needs more zing. Add more Parmesan if you'd like a creamier/cheesier pesto. If desired, you can thin out the pesto with more olive oil.

For pesto sauces, use about one jar of 5.6-ounce sauce for a 16-ounce package of pasta. The amount of pesto sauce needed for pasta per person would be about . 75 ounces of sauce for each 2 ounce (about 1 cup cooked) serving of pasta.

Acid in the form of vinegar or citrus juices can make a pesto taste less bitter and could even enhance the flavour of the sauce at the same time. In low concentrations, salt can be used to suppress bitterness, which is why people have been adding tiny amounts to coffee for decades. Always go easy to start with.

Citrus juice can efficiently cover the bitterness of the spinach and give a fresh flavour to it. You can use either lemon, lime or even orange juice for the purpose. As soon as the leaves get cooked, take them out in a bowl. Drizzle some citrus juice over them, give a light stir and let it sit for 15 minutes.

Swirl in flavored salt

Flavored salt is one of the quickest ways to upgrade any store-bought pesto since you just sprinkle, mix, and you're ready to serve. You don't want to oversalt the pesto, of course, so start by dusting a very small amount and add more to the pesto to taste. Garlic salt is a fantastic choice.

Pesto Variations

You can add anything from parsley to marjoram (a favorite!), mint to fresh oregano to your basil base. Or leave the basil out entirely! I like to add citrus zest on occasion, or switch up the type of nuts I use - toasted almonds and walnuts are favorites. Let me know if you try this and what you think!

Pistachios, almonds, and walnuts or even seeds like sunflower, sesame, and pumpkin can replace the traditional pine nuts in pesto. Pretty much any edible nut tastes delicious—just make sure to toast and cool the nut before grinding them into the sauce.

You'll want to be mindful of the sodium content. Some jars have more than 500mg per serving and the 2020-2025 Dietary Guidelines recommend you eat no more than 2,300mg per day. It would be hard to stay within those guidelines if you get more than 20% of your sodium from pesto.

Its scarcity, plus the fact that the plants are picked roots, soil, and all to ensure that only juvenile leaves make it into pesto, makes it extraordinarily expensive and something that only premium, artisan pesto makers can justify using.

What can I use instead of pine nuts in pesto? ›

Almonds would be my choice, they have a delicate flavor. Unsalted cashews work well also. Macadamia and brazil nuts are also really good, though not necessarily cheaper than pine nuts. I prefer pecans to walnuts, since they are somewhat sweeter.

Adding a small amount of acidity (lemon juice or vinegar) and balancing that with a little sweetness (sugar or honey) is the best way to take the edge off a pesto that tastes overwhelmingly of garlic. Almost every cuisine on earth makes use of garlic, and it's a vital component in pesto.

And wouldn't you know, cilantro happens to naturally share a chemical that is also used during soapmaking. So, for those of us who have a certain gene cluster, we find those chemicals to be very assertive, hence the soapy flavors coming through.

The most important tip: Be generous with salt and basil!

These form the main pesto flavour so you don't want to scrimp on them - it will lead to a bland taste. If your pesto looks too dry, add more oil. You can also add more lemon juice if you want a stronger kick.

Stay away from larger, darker leaves, they'll have a higher concentration. Young spinach is more tender and tends to be sweeter. Overcooking spinach can bring out the bitterness, as well. It only needs a couple minutes in boiling water/the frying pan, max.

Spinach is high in calcium and the insoluble form of oxalic acid, which forms crystals that stick onto your teeth as you chew on it. These crystals give that gritty, tannic feeling in your mouth and also give what some people characterize as a bitter taste to spinach.

One way to balance the bitterness is to add some fresh basil leaves to the pesto (for example, three ounces of arugula and one ounce of basil). Alternatively, you can add a tablespoon of fresh lemon juice or a simple splash of water to the food processor to counteract the bitterness.
