Easy Spinach Pesto Recipe (2024)

FAQs

Why is my spinach pesto bitter? ›

“Extra-virgin olive oil contains bitter tasting polyphenols coated by fatty acids, which prevent them from dispersing. If the oil is emulsified in a food processor, these polyphenols get squeezed out and the liquid mix turns bitter.

Properly made pesto tastes fresh and zingy and balanced, not muddy. Each flavor component is identifiable—the fragrant basil, the pungent garlic, the buttery olive oil and sweet pine nuts, the tangy cheeses—and yet none dominates. Basil is the star, for sure, but its perfume works in balance with the other ingredients.

Traditional pesto is a blend of fresh basil, garlic, pine nuts, extra-virgin olive oil, and Parmesan cheese. With a food processor, it comes together in just a few steps: Pulse the nuts, lemon juice, and garlic in the food processor until they're finely chopped. Add the basil and pulse again.

Anything sugary will work: granulated white sugar, honey, fruit juices, even sweet dessert wines. 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.

Primarily, I want to say: If you find spinach and other greens too bitter, add some apple cider vinegar or other acid when cooking. This acid will help balance with the bitter. When I cook spinach, I sauté some diced tomato (another acid) in oil for a minute or two, and then put in the spinach. Hope this helps.

So, how do you avoid bitter pesto? One way you can combat this is to put a small amount (1/4 cup or less) of water in with the ingredients (minus the olive oil), just enough to make a paste. Then, after processing, transfer the paste to a bowl and gently mix in the olive oil.

The most common reason for pesto tasting bitter is that the olive oil is past its best and has started to turn rancid. If the pesto has been made in a food processor or blender, there's also the possibility that it has turned bitter from the crude, sheering action of the blades.

Additions - Some roasted or fresh cherry tomatoes would be delicious, I like to add fresh basil leaves to the top too. Pesto usually has pine nuts but you could add some extra toasted ones into the sauce. To add some greens you could mix through some chopped fresh spinach.

Cashews. Cashews resemble pine nuts in color, texture and mild sweetness, and can be used as a substitute in just about any recipe. Stick to unsalted versions (roasted or raw varieties both work), and toast them to provide extra depth of flavor.

Why is pesto so expensive? ›

Italian pine nuts are considered the finest in the world and are therefore eye-wateringly expensive. To make cost savings, many big producers source their pine nuts from China. Not a big issue, you might think, but these pine nuts are notorious for leaving a metallic aftertaste for some people, and that can last weeks.

Pine nuts are classically used in pesto and toasting them before you add them allows their flavor to shine. Looking for a great recipe? Try adding them to Food Network Kitchen's Basil Pesto recipe. They're also delicious tossed into any salad, such as this lemony Kale with Golden Raisins and Pine Nuts salad.

Why is my pesto bland? It's likely because you need to add more basil or salt. You want your pesto to taste slightly too salty - that way when it's mixed with pasta the dish won't be bland.

If, on the other hand, the jar has been opened and left in a fridge for a day or two, it's most likely that the change in colour is simply a result of oxidation.

Pesto can be a bit on the chunky side, or almost like a uniform green paste. It really comes down to personal preferences or what you're using it for, but smoother pesto yields a better flavour and greener colour throughout whatever you toss it through.

Aged spinach leaves which are dark green in colour, often turn out to be slightly bitter in taste. To avoid such a scenario, opt for young spinach in the first place. Always buy spinach that is bright green in colour and has vibrant-looking leaves.

Spinach can become bitter when sautéed due to its high levels of oxalic acid, which can be released when the leaves are cooked for too long or at too high a temperature. Additionally, overcooking can break down the chlorophyll in the spinach, leading to a bitter taste.

To make arugula pesto less bitter, add basil to it. Basil is sweeter and softens up the spicy, bitter notes of arugula. We recommend using 1 part of arugula and 1 part of basil.
