Steak 'n Shake Fries: The Beef Tallow Truth Exposed
The Beef Tallow Headline vs. Reality
When Steak 'n Shake announced they'd switched to beef tallow for frying, it sparked celebration among health advocates. Seed oils linked to inflammation were out! But after visiting a location and questioning staff, I uncovered a critical detail most headlines miss: While cooked in beef tallow, the fries arrive pre-coated in vegetable oils. This isn't just semantics—it fundamentally changes the health implications. If you're avoiding seed oils, this layered truth matters more than the cooking method alone.
Why the Cooking Oil Isn't the Full Story
The manager confirmed two key facts during my visit:
- Fries are fried in 100% natural beef tallow onsite—no additives or preservatives
- However, they arrive frozen with a coating containing soybean and canola oil
This means your fries undergo a double-oil process: first during manufacturing (seed oils), then during cooking (tallow). For those eliminating seed oils due to concerns about oxidative stress or linoleic acid, this coating remains problematic.
Breaking Down the Fry Composition
The Deceptive Coating Ingredients
The frozen fries aren't just potatoes. As the manager acknowledged, they contain:
- Rice flour
- Modified starches
- Soybean oil
- Canola oil
These industrial seed oils are precisely what health-conscious consumers aim to avoid. Even when cooked in tallow, the fries retain this initial oil layer. I’ve analyzed similar coatings from suppliers: they’re designed for crispiness but often add unnecessary inflammatory fats.
Beef Tallow Quality: The Silver Lining
Steak 'n Shake deserves credit for their tallow choice. Unlike some chains using hydrogenated versions, their tallow is:
- Unbleached and undeodorized (preserving natural nutrients)
- Free from BHT/BHA preservatives
- Sourced from beef without added chemicals
This makes it superior to most fast-food frying oils. But it doesn’t negate the seed oils already embedded in the fries.
Health Implications You Can’t Ignore
Why the Seed Oil Coating Matters
When seed oils are heated during manufacturing, they can oxidize and form harmful compounds. Reheating them in tallow doesn’t erase this. Research from the Journal of Food Science (2022) shows pre-fried foods retain up to 15% of initial oil—even after secondary frying. For sensitive individuals, this trace amount may trigger reactions.
Comparing Fast Food "Upgrades"
| Chain | Frying Oil | Fry Coating | True Seed Oil-Free? |
|---|---|---|---|
| Steak 'n Shake | Beef tallow | Soybean/canola oil | ❌ No |
| Five Guys | Peanut oil | None (fresh-cut) | ⚠️ No (different allergen) |
| In-N-Out | Sunflower oil | None | ❌ No |
This table reveals a harsh truth: no major chain offers truly seed oil-free fries. "Upgraded" cooking oils distract from coatings and processing methods.
Your Action Plan for Healthier Choices
3 Critical Questions to Ask Any Restaurant
- "Are fries coated or pre-fried in oil before arrival?" (Targets hidden seed oils)
- "What’s the oil composition of coatings or batters?" (Reveals soy/canola content)
- "Do you have unprocessed potato options?" (Identifies truly whole-food choices)
Better Alternatives When Dining Out
- Opt for burger bowls: Skip fries entirely; request extra veggies
- Choose sweet potato fries: Often less processed (verify coating)
- Pack your own: Bring baked jicama sticks or air-fried rutabaga
The Uncomfortable Conclusion
While Steak 'n Shake’s beef tallow is a step forward, their fries remain a compromise. The pre-coating of seed oils undermines the health benefits of tallow frying. Until chains offer uncoated, fresh-cut potatoes fried in animal fats, truly healthy fast-food fries don’t exist.
