This is basically an anglo-ized variation on Lao Gan Ma ( https://mltshp.com/p/1M5SV ) spicy chili crisp. Frequently TJ's adaptations are kinda watered-down in some way -- not usually in terms of heat (TJ's pretty reliably stocks things like dried ghost pepper), but the flavor balance is usually lacking, or they don't seem to get the essence of whatever cuisine they're pushing.
But in this case the anglo-ization has benefits. First, the flavor balance is pretty good -- the first thing that hits you is the richness of the oil, followed by the salt and garlic, and then there's a slow burn from the pepper and onion that lingers pleasantly (pleasantly for yourself, not necessarily for the people around you). There's good pepper flavor while the heat is at the low/medium end of the scale. Second, the ingredient list is very straight forward: oil, vegetable matter and salt. Most of the crispy chili oil we've looked for in Chinese groceries have sulfites for preservation and sometimes other chemicals. They are probably harmless (or minimally harmful, unless you have a sensitivity) but it's hard to tell, especially if you don't read Chinese and the white label that was slapped on to make it legal to sell in the US got smudged.
Four bucks each at Trader Joe's, or $15/jar on Amazon.
