Is A1 Sauce Keto?

A1 sauce is one of the go-to condiments for meat. Besides, it was rebranded from ‘A1 Steak Sauce’ ever so recently; so that says a lot about how this sauce can and should be used. But is it keto-friendly and suitable if you are following the keto diet? Here is what you need to know.

So, is A1 sauce keto? A1 sauce is not particularly keto-friendly. It does include corn syrup and does provide 3 grams of net carbohydrate per serving (17g). That being said, you could eat A1 sauce on keto if you are to do so sparingly and are mindful of the carbohydrate content coming from the rest of your diet.

In reality, A1 sauce is never going to be your best option.

But while it’s not ideal; it can be eaten.

Just with a little mindfulness, as we shall now see below.

What Is In A1 Sauce?

A1 sauce is a tomato-based sauce that includes vinegar and a range of spices and flavorings.

The result is a relatively tart, salty, sweet, tasting sauce with a hint of pepper.

No wonder it’s ideal for steak!

In fact, the complete ingredient list for the original A1 sauce is as follows:

Tomato Puree (Tomato Paste, Water), Vinegar, Corn Syrup*, Salt, Raisin Paste, Crushed Orange Puree, Mixed Spices, Dried Garlic Powder, Caramel Colour (E150d), Dried Onions, Potassium Sorbate, Xanthan Gum, Celery Seeds, *Genetically Modified

I’ve flagged corn syrup there as that is the one we need to be careful of.

Although, tomatoes can include a lot of carbohydrates too, naturally.

But what does this all mean for our keto diet?

Let’s find out.

Can You Have A1 Sauce On Keto?

You can consume A1 sauce on keto, but you will need to keep to 1-2 serving sizes (1-2 tablespoons) to ensure you do not exceed your carbohydrate quota for the day.

While there are sauces out there that are much more carbohydrate-dense than A1, it still packs a fair share of carbs per serving.

3 grams in fact.

And while this is far from ideal, it doesn’t necessarily mean you cannot eat it while following the ketogenic diet.

What truly matters, at the end of the day, is your macros.

You need to ensure you keep your carbohydrates sufficiently low.

As low as 20-50 grams, according to the studies.

So, as long as you are keeping below that threshold, you should be okay.

It will mean being vigilant about how much you consume.

Now, remember, sauce is not the only source of carbohydrates in your diet.

So you essentially will need to work it out and stay within your limits.

Otherwise, you really will risk being knocked out of ketosis.

And that really does defeat the purpose of this diet!

Now, if you’re like me and you love your sauce – you may even need to restrict it altogether.

But if you can limit yourself, a small amount should be fine.

Just consider what it could be displacing though – like a side of vegetables.

How To Eat A1 Sauce On Keto

A1 sauce is steak sauce first and foremost, so it naturally follows that you should eat this sauce with steak!

However, you can also consume it with other meats – it pairs nicely with chicken, too.

Other than this, consider drizzling a small amount over a salad, or with some low-carbohydrate vegetables!


A1 sauce is not the best sauce for the keto diet, but that being said, that doesn’t mean you cannot have it.

You just need to be cautious of how much you are having and what you are having it with.

In reality, 1-2 servings in a day are the most you will likely be able to consume.

That will leave you with sufficient carbs for the rest of your diet.

Otherwise, do consider one of the alternatives referenced here today.
