Understanding the Three Potato Categories
To determine where Yukon Golds fall, it's essential to understand the three main categories of potatoes based on their starch content and moisture levels: high-starch, low-starch (waxy), and all-purpose (medium-starch). This classification directly influences how a potato cooks and its final texture.
High-Starch (Floury) Potatoes
High-starch potatoes, like the classic Russet, are low in moisture, giving them a dry, fluffy, or mealy texture when cooked. The cells separate easily, which makes them perfect for creating light and fluffy mashed potatoes or for baking and frying, where a crisp exterior and tender interior are desired. However, this same quality causes them to fall apart in soups and salads.
Low-Starch (Waxy) Potatoes
Conversely, low-starch potatoes, such as Red Bliss and new potatoes, have a high moisture content. This allows them to hold their shape exceptionally well when boiled, roasted, or pan-fried, making them the top choice for potato salads, soups, stews, and gratins. Because their cell structure remains intact, they do not produce a fluffy mash.
Medium-Starch (All-Purpose) Potatoes
This is where the Yukon Gold shines. All-purpose potatoes like the Yukon Gold occupy the middle ground, offering a perfect balance of starch and moisture. This versatility is why they are a pantry staple, excelling in almost any cooking application. They provide the best of both worlds: they can mash beautifully into a creamy consistency while also holding their shape better than a Russet when roasted or boiled in a soup.
Why Yukon Golds Are Often Misunderstood
The misconception that Yukon Golds are low in starch likely stems from a comparison with high-starch Russets. Because Yukon Golds don't fall apart and become fluffy in the same way, some home cooks assume they are a waxy, low-starch variety. However, their balanced composition gives them a rich, buttery, and creamy texture that sets them apart and makes them suitable for a wide range of preparations. This medium starch level allows them to crisp up nicely when roasted while retaining a delicious, creamy interior.
Cooking with Yukon Golds vs. Other Varieties
The best cooking methods for Yukon Golds leverage their unique balance of starch and moisture. For creamy mashed potatoes, many chefs prefer Yukons because they are less likely to become gluey than Russets if overworked. For roasting, they develop a flavorful, crispy edge while the inside remains tender and creamy. In soups, they hold their shape well enough to provide satisfying chunks but can also release some starch to slightly thicken the broth.
Comparison Table: Yukon Gold vs. Other Potatoes
| Feature | Yukon Gold (Medium Starch) | Russet (High Starch) | Red Potato (Low Starch) |
|---|---|---|---|
| Starch Content | Medium | High | Low |
| Moisture Content | Medium | Low | High |
| Cooked Texture | Creamy, buttery, dense | Fluffy, light, mealy | Firm, waxy, solid |
| Best For | Mashing, roasting, gratins, soups | Baking, frying, fluffy mash | Salads, boiling, gratins, soups |
| Holds Shape? | Well | Poorly | Excellent |
| Skin Texture | Thin, smooth | Thick, rough | Thin, smooth |
The Genetic Origins of Yukon Golds
The Yukon Gold potato was developed in Canada at the University of Guelph by Gary Johnston in the 1960s. It was a crossbreed between a North American white potato and a wild yellow South American potato. This unique lineage gave it the sought-after golden flesh, thin skin, and perfect all-purpose texture that has made it a kitchen favorite for decades.
Conclusion
In short, the answer to the question "Are Yukon Gold potatoes low in starch?" is no. They are a medium-starch, all-purpose potato, celebrated for their exceptional versatility and buttery flavor. Their position in the middle of the starch spectrum, between starchy Russets and waxy Reds, is the key to their widespread appeal and why they perform so well in a multitude of cooking applications. Next time you're cooking, knowing this distinction can help you choose the right potato for a perfectly textured dish.

Key Takeaways
- Medium Starch Level: Yukon Gold potatoes are an all-purpose variety with a medium starch and moisture content, not a low-starch one.
- Versatile for Cooking: Their balanced composition allows them to excel in almost any dish, from mashing to roasting, where they achieve a creamy yet intact texture.
- Holds Shape Well: Unlike high-starch Russets that fall apart, Yukon Golds hold their shape, making them suitable for gratins, soups, and salads.
- Naturally Creamy Flavor: They possess a naturally buttery and creamy flavor, requiring less added fat to achieve a luxurious consistency in dishes like mashed potatoes.
- All-Purpose Substitute: While they are not low-starch, their versatility means they can often be used as a substitute for both high and low-starch potatoes, with slightly different results.
- Thin Skin: The skin on Yukon Gold potatoes is thin and edible, offering additional nutrients and making preparation easier for many recipes.
FAQs
Question: How do Yukon Gold potatoes differ from Russet potatoes in terms of starch? Answer: Yukon Gold potatoes have a medium starch content and medium moisture, while Russet potatoes are high in starch and low in moisture. This gives Yukon Golds a creamy texture and Russets a light, fluffy, and dry texture when cooked.
Question: Are Yukon Gold potatoes suitable for making mashed potatoes? Answer: Yes, Yukon Golds are an excellent choice for mashed potatoes. Their medium starch content prevents them from becoming gluey if overworked, and they produce a creamy, rich, and naturally buttery mash.
Question: What happens if I use Yukon Gold potatoes for a potato salad? Answer: Yukon Gold potatoes hold their shape well enough for potato salad, unlike high-starch varieties. They will result in a firmer texture than traditional waxy potatoes but will not fall apart and create a mashed potato-like salad.
Question: Why are some potatoes classified as 'low starch'? Answer: Low-starch potatoes, also known as waxy potatoes (like Red Bliss or new potatoes), have a high moisture content. This is why their cell structure stays intact during cooking, allowing them to hold their shape.
Question: Can I substitute Yukon Gold potatoes for Russet potatoes when making french fries? Answer: While you can use them, Russet potatoes are generally preferred for french fries due to their high starch and low moisture, which yields a crispier fry. Yukon Golds will produce a delicious fry with a creamier interior rather than a fluffy one.
Question: Why are Yukon Gold potatoes considered an 'all-purpose' potato? Answer: Yukon Gold potatoes are labeled 'all-purpose' because their balanced medium starch and moisture levels make them suitable for a wide variety of cooking methods, from mashing and roasting to boiling for soups and salads.
Question: Is the skin on Yukon Gold potatoes edible? Answer: Yes, the skin of Yukon Gold potatoes is thin and perfectly edible. Many people choose to leave it on when cooking to preserve nutrients and enhance the flavor.
