Siete is the rare brand where the seed-oil claim holds across the entire chip lineup, not just one hero product. It earns its 4.5 on that consistency and the short ingredient lists. What keeps it from higher is the price and the fact that a cassava-flour chip is still a starchy snack, not a health food.
Yes, Siete chips are fried in avocado oil, and as of September 2026 that is true of all three chip lines: the grain-free tortilla chips, the Maiz nixtamalized corn chips, and the potato chips. No canola, soybean, sunflower, or safflower oil appears on any of those labels. If the only question is “can I eat these without seed oils,” the answer is a clean yes.
The more useful question is whether they are worth buying over a conventional chip that costs a third as much, and there the answer is more nuanced. Siete does the hard thing well: it holds one standard across a whole catalog. But it is now owned by PepsiCo, the chips are expensive, and the grain-free versions trade corn’s downsides for cassava’s. This review covers where that trade lands.
What’s in it
The grain-free Sea Salt tortilla chips read: cassava flour, avocado oil, coconut flour, ground chia seed, sea salt. Five ingredients, one of them the frying oil. The Maiz corn chips are shorter still: nixtamalized corn, avocado oil, sea salt. The potato chips use avocado oil as the fry medium as well. Across all three, avocado oil is the only added fat.
That consistency is the whole case for Siete. Plenty of brands put avocado oil in one marquee product and a seed oil in everything else on the shelf. Siete runs three structurally different products, a grain-free flour chip, a masa corn chip, a fried potato chip, and keeps the same oil in all of them. When PepsiCo acquired the brand in 2024 for around 1.2 billion dollars, the reasonable worry was a quiet reformulation to cheaper oil. It has not happened yet. It is still worth a label glance every few months, because acquisitions are exactly where these changes tend to slip through.
What is inthe chip is the catch. Cassava flour is a starch. It is grain-free and gluten-free, which is a real benefit if you need that, but nutritionally it behaves much like other refined starches and raises blood sugar accordingly. The grain-free chips are a clean swap for a chip. They are not a food you should eat more of because they are “healthy.”
Seed oil status
Avocado oil is the only added oil across the grain-free tortilla chips, Maiz corn chips, and potato chips. Confirmed against Siete's published ingredient statement for Grain Free Sea Salt Tortilla Chips (https://sietefoods.com/shop/chips-and-snacks/grain-free-tortilla-chips/sea-salt-grain-free-tortilla-chips/), September 2026.
Pros and cons
What holds up
- Avocado oil is the frying medium across all three chip lines, not just one hero product
- Short, readable ingredient statements: five items on the grain-free chips, three on the Maiz
- Grain-free and gluten-free, which the corn-chip alternatives are not
- Sold in most conventional grocery stores now, not just health retailers
What to weigh
- 5 to 7 dollars a bag, roughly triple a conventional tortilla chip
- Cassava flour is starchy and high-glycemic; this is a clean swap, not a diet food
- Grain-free chips go stale and soft noticeably faster once opened
- Now owned by PepsiCo (2024), so the formulation is worth re-checking periodically
Price and where to buy
Siete runs 5 to 7 dollars for a 5-ounce bag, roughly triple a conventional tortilla chip and about double a bag of Boulder Canyon. The Maiz corn chips are usually the best value in the range and, with the shortest ingredient list, the easiest to recommend without caveats. The grain-free chips are the premium tier and also the ones that go stale and soft fastest once the bag is open, so buy the size you will finish in a week.
Distribution is no longer a problem. Siete is in most conventional grocery chains now, not just Whole Foods and natural-foods stores. On Amazon the multipacks bring the per-bag price down closer to 4 dollars, which is the point where the premium starts to feel reasonable rather than steep.

Who it’s for, and who it isn’t
Buy it if
Anyone who wants a chip for salsa or nachos without soybean or sunflower oil, and who also needs grain-free or gluten-free.
Skip it if
Anyone watching carbs or blood sugar closely, or unwilling to pay a strong premium for a snack food.
How it compares
Against Boulder Canyon, Siete is the choice when you need grain-free or gluten-free, or when you specifically want a tortilla-style chip for salsa and nachos. Boulder Canyon is the better everyday pick for a plain salted potato chip: same avocado frying oil, a genuine potato chip texture, and half the price. If gluten is not a concern and you just want chips with a sandwich, Boulder Canyon wins on value.
Against Jackson’s Honest, the difference is the oil itself. Jackson’s fries in organic coconut oil, which is more heat-stable than avocado oil but carries a faint sweetness into the chip. Siete’s avocado oil is flavor-neutral. If you want the most oxidatively stable option and do not mind a hint of coconut, Jackson’s; if you want the chip to taste like a chip, Siete.
FAQ
Are all Siete chips fried in avocado oil?
Yes. As of September 2026, the grain-free tortilla chips, the Maiz nixtamalized corn chips, and the potato chips all use avocado oil as the only added oil. No canola, soybean, sunflower, or safflower oil appears on any of those labels.
Did the recipe change after PepsiCo bought Siete?
Not as of our last check. PepsiCo acquired Siete in 2024 and the chip ingredient statements are unchanged since then. Because acquisitions are a common point for quiet reformulation, it is worth a label glance every few months.
Are Siete chips healthy?
They are a clean swap for a chip, not a health food. Cassava flour is starchy and raises blood sugar much like other refined starches. The win is the oil and the short ingredient list, not the macros.
