There is a reason people over 40 get misty-eyed talking about McDonald’s fries. From the 1940s until 1990, McDonald’s cooked their french fries in beef tallow. The result was a fry so crispy, so golden, and so deeply savory that it became the defining fast-food experience of an entire generation.
Then they switched to vegetable oil. The fries were never the same.
I have spent the last several months trying to recreate that experience at home. I bought five different beef tallow brands, sourced three varieties of potato, and dialed in a double-fry technique that produces fries every bit as good as what McDonald’s served in 1985. Here is everything I learned.
Why McDonald’s Used Beef Tallow (And Why They Stopped)
McDonald’s original french fry recipe was developed by Ray Kroc’s team in the 1950s, and beef tallow was the secret. The fat did three things that vegetable oil cannot.
First, the flavor. Beef tallow contains natural glutamates — savory compounds that make food taste richer without adding any seasoning. When a potato hits 375F tallow, those compounds bind to the starch and create a flavor profile that is impossible to replicate with seed oils.
Second, the crispiness. Tallow is a saturated fat, which means it solidifies as the fry cools. That thin shell of fat on the outside of the fry is what creates the shatter when you bite into it. Vegetable oils stay liquid, so fries cooked in them go limp faster.
Third, the color. Tallow produces a deep golden-brown color that looks appetizing in a way that pale, vegetable-oil fries never do.
In 1990, a businessman named Phil Sokolof ran full-page newspaper ads attacking McDonald’s for using “beef fat” in their fries, claiming it was causing heart disease. McDonald’s caved to the pressure and switched to a blend of vegetable oils. The nutrition debate has shifted dramatically since then — we now know that saturated fat was wrongly demonized and that the seed oils McDonald’s switched to carry their own health concerns. But the damage was done.
The good news is that you can cook fries in tallow at home, and they taste better than anything you can buy at a drive-through today.

1. 100% Pure Grass Fed Beef Tallow (4 lbs) — Best Overall for Fries
Check Price on Amazon{rel=“sponsored”}
This is the tallow I reach for every time I make fries at home, and it is the one I recommend to everyone who asks.
The 4-pound tub gives you enough volume to fill a Dutch oven to proper frying depth — about 3 inches — with enough left over for a second session. That matters because the number one mistake people make with tallow fries is not using enough fat. If your fries are sitting on the bottom of the pot instead of floating freely, you will get soggy, greasy results no matter what brand you use.
Flavor in the fryer: The fries came out with that unmistakable beefy sweetness that makes tallow fries legendary. Not overpowering — you still taste the potato first — but there is a depth and richness that vegetable oil simply cannot produce. My taste testers described it as “the way fries are supposed to taste.”
Smoke point performance: I measured consistent performance at 400F before visible smoke. That gives you a comfortable buffer above the 375F target for the second fry. The oil stayed clear and clean through three complete fry sessions.
Reusability: After straining through a fine-mesh sieve, this tallow came back looking and performing almost like new for the next batch. I got four full fry sessions before noticing any degradation in color or flavor.

2. Traverse Bay Farms (32 oz) — Best Budget Option
Check Price on Amazon{rel=“sponsored”}
If you are making tallow fries for the first time and you do not want to invest heavily, Traverse Bay gets the job done at a fraction of the cost.
This is conventional (not grass-fed) tallow, and the flavor reflects that — slightly stronger beefy note, less refined, more of that old-school fast-food character. Some people actually prefer this for fries specifically because it leans into the nostalgia.
Smoke point tested at about 385F, which is lower than the grass-fed options. That means you have less room for error at 375F for the second fry. I had to watch the thermometer more carefully with this one, especially during the initial temperature recovery after dropping cold potatoes into the pot.
Perfectly good for fries. Not the best for delicate cooking. At this price, it is an easy entry point.
3. South Chicago Packing Wagyu — Best Premium Fries
For the best-tasting fries I produced during the entire testing process, the wagyu tallow from South Chicago Packing wins. The higher monounsaturated fat content creates a fry that is noticeably smoother and more buttery than standard tallow.
The 42-ounce jar gives you enough for deep frying, which is rare for a premium product. But the price per ounce makes this a special-occasion choice. I would not use it for a Tuesday night batch of fries for the kids. I would absolutely use it when I want to impress someone.
The Double-Fry Technique: How to Make Perfect Tallow Fries
This is the method that separates good fries from legendary fries. The double-fry technique is how professional kitchens and the original McDonald’s process worked. One fry cooks the potato through. The second fry creates the crust.
Potato Selection and Prep
Use Russet potatoes. They have the highest starch content, which means they crisp better and stay fluffy inside. Yukon Golds work but produce a denser fry. Red potatoes are too waxy — skip them.
Cut them consistently. Aim for about 1/4 inch thick and 3 to 4 inches long. Uniform cuts mean uniform cooking. If half your fries are thin shoestrings and the other half are steak cuts, you will end up with a mix of burnt and undercooked.
Soak in cold water for at least 30 minutes, up to overnight in the refrigerator. This removes surface starch, which is the biggest enemy of a crispy fry. Surface starch causes fries to stick together and turns brown too fast.
Dry them completely. After soaking, drain the potatoes and pat them bone dry with clean towels. Water hitting 325F tallow causes violent splattering and drops the oil temperature. Every drop of moisture is working against you.
First Fry: 325F for 5 to 6 Minutes
Heat your tallow to 325F in a Dutch oven or deep heavy pot. Use a clip-on thermometer — guessing temperatures is how people burn tallow and ruin fries.
Drop the potatoes in small batches. Do not overcrowd the pot. You want each fry to have room to float freely. When you add cold potatoes, the temperature will drop — that is normal. Wait for it to recover to around 300F before you start timing.
Fry for 5 to 6 minutes. The potatoes should be cooked through but still pale — no significant browning. They will look limp and unappetizing. That is exactly right. You are cooking the interior, not the exterior.
Remove with a spider strainer or slotted spoon and let them rest on a wire rack over a sheet pan. Do not use paper towels — they make the fries soggy. Let them rest for at least 10 minutes, up to 2 hours at room temperature.
Second Fry: 375F for 2 to 3 Minutes
This is where the magic happens.
Bring your tallow up to 375F. The higher temperature is critical. It creates rapid dehydration of the outer surface while the interior stays fluffy. The thin layer of tallow on the fry solidifies almost instantly when it hits air, creating that signature crunch.
Fry for 2 to 3 minutes until golden brown. Watch the color — you want deep gold, not dark brown. These go from perfect to overcooked in about 30 seconds, so stay close.
Remove immediately, let excess oil drip for about 10 seconds, then transfer to a clean wire rack. Season with fine salt immediately while the surface is still hot and sticky enough for the salt to adhere.
Serve within 5 minutes. Tallow fries are at their absolute best right out of the fryer. After 10 minutes, the crust starts to soften.
Temperature Control Tips
Temperature management is the difference between restaurant-quality fries and disappointing ones. Here are the practical details that most recipes leave out.
Use at least 2 to 3 pounds of tallow. More oil means more thermal mass, which means the temperature recovers faster when you add cold potatoes. Skimping on oil volume is the most common mistake.
Invest in a good thermometer. A clip-on deep-fry thermometer costs about $10 and eliminates guesswork. Digital instant-read thermometers work too, but you have to check manually.
Adjust your burner between fries. After the first fry at 325F, you need to bring the temperature up to 375F. Start increasing the heat while the fries are resting. Do not wait until the last minute.
Fry in small batches. A large batch of cold potatoes can drop your oil temperature by 50F or more. If the temp drops below 300F, you get greasy, oil-logged fries. Three small batches always beat one big batch.

How to Reuse Tallow After Frying
One of the biggest advantages of tallow over vegetable oil is reusability. Tallow is a stable saturated fat that does not break down as quickly as polyunsaturated seed oils. With proper care, you can reuse the same batch of tallow for 4 to 6 frying sessions.
Step-by-Step Reuse Process
- Let the tallow cool to about 150F after frying. Still warm, but not dangerously hot.
- Strain through a fine-mesh sieve lined with cheesecloth into a clean glass jar or the original container. This removes all the potato bits and debris that would burn during the next session.
- Store in the refrigerator. Strained tallow will solidify into a clean white or cream-colored block. It keeps for 2 to 3 months in the fridge between uses.
- Check before reusing. Before your next fry session, look at the tallow. It should be white to pale yellow. If it is dark brown, smells rancid or sharp, or foams excessively when heated, discard it and start fresh.
When to Discard
- The tallow is noticeably darker than when you started
- It produces excessive foam when heated
- It smells sharp, rancid, or “off”
- The smoke point has dropped noticeably (smoking before reaching 350F)
- It has been stored for more than 3 months

Seasoning Ideas for Tallow Fries
Once you have the basic fry technique dialed in, here are seasoning combinations that work especially well with tallow’s natural flavor.
Classic: Fine sea salt only. Let the tallow do the talking. This is my default.
Garlic parmesan: Toss hot fries with finely grated Parmigiano-Reggiano, garlic powder, and chopped parsley. The fat on the surface of the fry makes the cheese stick perfectly.
Cajun: Dust with a mix of paprika, garlic powder, onion powder, cayenne, and black pepper. The heat pairs beautifully with the beefy richness of the tallow.
Truffle salt: If you want to impress, truffle salt on tallow fries is genuinely special. The earthy truffle compounds complement the beef fat in a way that does not work with vegetable oil fries.
Malt vinegar: The British chip shop approach. Tallow fries with malt vinegar and salt is one of the simplest and best combinations in all of fried food.
Frequently Asked Questions
What kind of tallow did McDonald’s use for fries?
McDonald’s used a blend of beef tallow and a small percentage of cottonseed oil for their fries from the 1940s through 1990. The tallow was the dominant fat and provided the signature flavor. They switched to vegetable oil in 1990 following public pressure about saturated fat and heart disease — a decision that most food historians and many nutritionists now consider a mistake.
How much tallow do I need for french fries?
Plan on 2 to 3 pounds (32 to 48 ounces) for a standard Dutch oven. You need at least 3 inches of depth so the fries float freely. The 4-pound grass-fed tallow{rel=“sponsored”} gives you enough for the initial fry plus leftovers for the next session.
Can I mix tallow with other oils for frying?
You can, and McDonald’s actually did. A mix of about 80% tallow and 20% vegetable oil gives you a slightly higher smoke point while retaining most of the flavor. I prefer 100% tallow, but the blend is a reasonable compromise if you are short on tallow.
Why do my tallow fries taste greasy?
Three likely causes: your oil temperature was too low, you overloaded the pot with too many fries at once, or you did not dry the potatoes thoroughly before frying. Temperature is the most common culprit. If the tallow is below 300F when the potatoes go in, they absorb fat instead of frying in it.
Are tallow fries healthier than fries cooked in vegetable oil?
Tallow is a stable saturated fat that does not oxidize easily at high temperatures. Vegetable oils — especially soybean, canola, and corn oil — are polyunsaturated fats that produce harmful oxidation byproducts when heated repeatedly. From a cooking chemistry standpoint, tallow is the safer choice for deep frying. The broader nutritional debate about saturated fat is more nuanced, but for the specific context of frying, tallow has clear advantages. Our guide on tallow nutrition covers this in more detail.
How many times can I reuse tallow for fries?
With proper straining and storage, quality tallow can handle 4 to 6 frying sessions. The key is filtering out all food particles after each use and storing the strained tallow in the refrigerator. Discard when the color darkens significantly, the smell changes, or it foams excessively when heated.
Bottom Line
If you want french fries that taste the way they did before every restaurant switched to vegetable oil, cooking in beef tallow is the answer.
Best overall: 100% Pure Grass Fed Beef Tallow (4 lbs){rel=“sponsored”} gives you the quality, volume, and smoke point to make restaurant-caliber fries at home. It is what I use every week, and it is what I recommend first.
Best budget: Traverse Bay Farms (32 oz){rel=“sponsored”} gets you into the tallow fry game at the lowest cost.
The technique matters as much as the tallow. Soak your potatoes, dry them thoroughly, nail the double-fry at 325F then 375F, and do not overcrowd the pot. Follow those rules with any decent tallow and you will produce fries that make people ask what your secret is.
The secret is that there is no secret. It is just beef tallow. The way fries were always meant to be cooked.
