Is Shallot Acidic or Alkaline?
Shallot (fresh) is alkaline: Negative PRAL: alkalizing after digestion.
Classification
Alkaline like their larger relative: shallots come in at −3.1 because these small onions bring potassium and hardly any protein. They taste milder and more delicate than regular onions, but in a vinaigrette or red wine sauce they're usually just one ingredient among many. One finely chopped shallot adds little to the balance, while plenty of braised shallots as a vegetable side make a noticeable difference.
In the Vegetables & Salad category, shallot (fresh) ranks #69 of 110, sorted from alkaline to acid-forming. More alkaline options include Red cabbage (−3.2), Endive (−3.2), Sauerkraut (−3.3). More acid-forming are Carrots (−3.1), Eggplant (−3.0), Green asparagus (−3.0).
Acidic or alkaline: PRAL, not pH
On this site, acidic and alkaline refer to the PRAL (potential renal acid load). It estimates what a food leaves behind once it has been digested: a positive value is acid-forming, a negative value is alkalizing. That is different from the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0, so it is alkalizing. Your diet does not change your blood pH. It does change how much acid your kidneys have to deal with.

Frequently Asked Questions
Is shallot acidic?
It depends on what you mean by acidic. The pH describes the food itself, for example how sour it tastes. The PRAL describes what it leaves behind after digestion: Shallot (fresh) has a PRAL of −3.1 per 100 g, so it counts as alkaline in your daily acid-base balance.
How much shallot do I need for a noticeable effect?
A serving (150 g) of shallot adds −4.6 to your daily balance. For comparison: an egg is around +5.4, a slice of cheese around +6. So one serving of shallot roughly offsets one of them.
Why is shallot alkaline even though it is not a typical alkaline food?
The PRAL depends on the minerals left over after digestion, not on taste or pH. Shallot provides more potassium, magnesium and calcium than phosphorus and protein, so the balance is negative (−3.1).
