Arugula pesto, the secret lies in the olive oil.

Arugula pesto is a pleasant alternative to the classic Genovese pesto or basil pesto. Its uses are essentially identical, so you can use it as a condiment for first courses, to make savoury pies, and to prepare good appetizers. Just spread it on croutons to obtain a mouthwatering entrée. Just like traditional pesto, this is also quick and easy to make. This does not imply, however, that achieving a great outcome is simple.

The secret to preparing an excellent arugula pesto lies in the choice of oil. Oil is one of the main ingredients for a good homemade pesto, so the better the oil, the better the result.

Among the varieties available on the market, the winner still goes to extra virgin olive oil. It is obtained by pressing olives and must have an acidity of 1% or less. Low acidity is important, as it indicates that the oil was obtained from ripe olives, but that alone is not enough to guarantee high quality.

Recipe arugula pesto

Preparation arugula pesto

  • To prepare the arugula pesto, start by washing the arugula very well, then dry it and put it in the blender.
  • Add the pine nuts, the Parmigiano Reggiano cheese, the pecorino cheese, the garlic clove, the salt, and a little oil.
  • Start blending everything at low speed and gradually add the remaining olive oil.
  • Continue blending until you obtain a well-combined and fluid cream.
  • Finally, close the jar of pesto and place it in the refrigerator, where it will retain its flavour and colour for more than a month.

Ingredients arugula pesto

  • 100 gr. arugula50 gr. aged pecorino cheese
  • 50 gr. 48-month Parmigiano Reggiano cheese
  • 30 gr. pine nuts
  • 1 clove of garlic
  • 150 ml. extra virgin olive oil
  • salt to taste

How to choose the most suitable oil for the arugula pesto?

To prepare homemade arugula pesto, it is important to choose a good extra virgin olive oil and to be able to recognise the various levels of quality. For example, extra virgin olive oil can be extracted by centrifugation or by cold pressing. In the first case, the label suggests that it is the first oil produced by pressing the olives (and is considered the best). In the second case, the product is obtained with the more traditional method that does not use hot water to extract the oil.

There is also virgin olive oil, which is obtained directly from pressing the olives and which, like extra virgin oil, only undergoes physical and mechanical treatments but not chemical ones.

When buying olive oil, you should be wary of fraud. One of the most common is passing off coloured seed oils as olive oil. In fact, olive oils have a yellow-green colour, while seed oils are almost colourless, having undergone decolourization treatments. Therefore, you can only use your sense of smell to differentiate between the two types. You should be sceptical if the oil you bought doesn’t smell anything like olive oil.

A few misconceptions regarding high-quality oil

Additionally, watch out for products whose origin is unclear and oils that are sold at prices that are too low in comparison to the norm. Lastly, there are a lot of fallacies about oil that need to be debunked. The most prevalent one is that there are no fatty or lean oils; in actuality, they all contribute the same quantity of fat. Because olive oil is more viscous and fragrant, its flavour is perceived as being more intense, giving the sense that it is fattier than other oils.

Another fallacy is that the so-called diet oils don’t actually aid in weight loss, despite popular belief. Actually, this kind of oil is distinguished by the addition of vitamins that aid in stabilising it; yet, the caloric content remains unchanged.

Finally, the idea that vegetable oils are always low in saturated fats must also be dispelled. In fact, coconut and palm oils are widely used in the confectionery industry and contain high percentages of saturated fats.

Be mindful of oil conservation

If your goal is to prepare an excellent arugula pesto, it is not enough to use an adequate oil, but you will also have to pay attention to its conservation. Oil deteriorates in heat, so the ideal way is to store it in a cool and dark place, away from other products that have very strong odours.

A bottle of oil should be consumed within 18 months of the indicated date on the label. In addition to its ability to make dishes tastier, olive oil has earned a privileged place in the hit parade of “good” foods for its numerous beneficial properties demonstrated by various studies.

It has been demonstrated that olive oil, particularly extra virgin olive oil, can help prevent the activity of free radicals, which accelerate the ageing process and the development of arteriosclerosis. Furthermore, because extra virgin olive oil is high in unsaturated fats and low in saturated fats, it tends to produce solely “good” cholesterol (HDL) rather than “bad” cholesterol (LDL). This implies that it also aids in preventing heart disease. It is also used as an effective treatment tool for diabetic patients.

The main ingredient of arugula pesto

Oil is essential for arugula pesto, but arugula is equally important. Arugula is a widely consumed vegetable in Italy and is the protagonist of simple or complex dishes.

Its versatility makes it suitable for a little bit of everything, from pizzas to salads. Like all vegetables, it is lactose-free and gluten-free. It also boasts a low nickel content, so it is suitable for recipes specifically designed for those who suffer from food intolerances.

When used in pesto, arugula adds a subtle yet fragrant taste. Additionally, it has strong nutritional qualities, just like basil. It has a lot of fibre, which helps with digestion; vitamin A, which is good for eyesight; and vitamin E, which has anti-tumour properties. Additionally, it has a remarkable amount of calcium, which is not always present in plant-based foods. Arugula has high vitamin C content and a relatively modest calorie consumption (28 kcal per 100 grams).

Arugula, a precious ingredient in the kitchen

Arugula is not only the star of this particular pesto but also a valid resource in all its forms; in fact, it boasts many applications in any type of recipe. It can be used as a salad vegetable, perhaps accompanied by fruits to add visual appeal and a little of depth to the flavour.

Arugula makes great stuffing for piadinas, pizza, and sandwiches. It pairs very well with raw ham and speck, and generally with extremely good sausages and cured meats. It functions as a vegetable like cabbage and lettuce, but it can also be used as a first-course condiment, somewhat like celery, coriander, and parsley.

Finally, it can be used as a garnish for gourmet appetisers, which take full advantage of its colour and strong flavour.

Pecorino and Parmigiano, an interesting combination

Arugula pesto differs from the original pesto with just a few ingredients. We certainly find aged cheeses, whose role is to ensure flavour, compactness, and an irregular texture. The official recipe for the classic Genovese pesto requires the use of Grana Padano cheese and Fiore Sardo cheese, a type of pecorino belonging to the Sardinian dairy tradition.

However, they suggest a little twist on the theme for this recipe, asking you to use the “classic” pecorino cheese and 48-month Parmigiano cheese. The first is sufficiently firm and flavourful to encourage a good blend. However, in terms of taste, pecorino cheese is unquestionably more accessible and manageable.

Their inclusion contributes to the nutritional value of this arugula pesto, just like in the traditional version. Both are rich in proteins, calcium, and vitamin D, in a more concentrated form than the milk from which they were made.

Arugula Pesto, one of the many variations of pesto

Pesto is more than a recipe; it is actually a real concept that gives life to a vast range of sauces. Pesto is excellent for seasoning pasta and creating truly delicious appetizers. This seasoning is made with the pestle and mortar, with which the ingredients are reduced to pulp. In this way the fragrance is preserved, making the pesto a truly exquisite seasoning.

There are many types of pesto. Some of these are quite faithful to the classic recipe, as they do not replace basil but integrate it with other aromatic herbs (such as sage).

Some types of pesto propose a radical reinterpretation, that is, the passage to the mixer or the use of vegetables. An example? Carrot pesto, which is sweeter than the classic one. What about pesto with peppers? A vibrant, robust pesto that’s ideal for seasoning pasta.

The most common questions about pesto

How to make arugula pesto less bitter?

Arugula is an aromatic herb rather than a real vegetable. For this reason, it could give off strong and slightly bitter scents. Basically it is a pleasant ingredient, but if you want to reduce the bitterness, just add a few walnuts, which adapt very well to the recipe.

How can I use arugula pesto?

You can use arugula pesto as a traditional pesto. It can be used to make gourmet appetisers as well as pasta sauces. It looks like a “cream” with an irregular grain, aromatic, and easy to spread.

How many calories does arugula pesto have?

The recipe is calibrated for a very small jar, or for the sauce of about eight portions of pasta. According to these doses, it should provide a total of 1500 kcal.

Can pesto be frozen?

Yes, pesto can be frozen. When needed, simply defrost it at room temperature to use it as a sauce.

Do we have any pesto recipes? Of course we do!
