Rubio’s KETO Friendly Options for the Low-Carb Diet (2022)

Rubio’s has some really delicious seafood tacos! It’s an American restaurant chain offering a fusion between seafood and Mexican cuisine.

Think of it like Chipotle but with a focus on fish!

Rubio’s philosophy goes way beyond just taste. Did you know? They source sustainable seafood and the menu is free from MSG or artificial sweeteners.

The very first Rubio’s opened in 1983. It all started when the founder, Ralph Rubio, encountered a fish taco at a local eatery in Baja California.

He was thrilled by the recipe and decided to make a business out of it. (Yup, they invented the fish taco before fish taco was “cool”.)

Fast forward to 2021, there are 160 Rubio’s across the United States serving multiple varieties of fish tacos – Shrimp, Mahi Mahi, Wild Salmon – they’ve got it all.

If you are on a ketogenic diet, Rubio’s brings a lot to the table (literally!)

Rubio’s offers cheese taco shells for just 2g net carbs. It’s a crispy layer of cheese that replaces your carb-laden corn tortillas. Simply order your favorite tacos and ask for the keto swap.

But that’s not all.

They also have various low-carb offerings like guacamole, cauliflower rice, chopped salads, and much more. Read on for a complete guide to surviving keto at Rubio’s.

Is Rubio’s Keto-Friendly?

Tex-Mex food is one of the most keto-friendly cuisines out there.

Here are three simple reasons backing my claim:

  1. All Tex-Mex restaurants offer customizable bowls. So you can choose your own ingredients.
  2. They have low-carb protein choices, a lot of salady-greens, and keto-friendly salsas.
  3. If all else fails, you can always fall back to a serving of fresh guacamole!

And by the way, Rubio’s Coastal Grill checks off all the boxes.

But that’s not all.

Rubio’s changed the whole game with the launch of their keto-style menu. Back in 2019, they came up with the ultimate low-carb replacement for taco shells.

They call it the Keto-Style Cheese Taco.

The keto trend really picked up momentum during 2019. A huge number of people jumped on the wagon and Rubio’s was bombarded with “low-carb” order requests each day.

Customers would ask for a lettuce wrap instead of the taco shell, or simply order the taco in a bowl (me included!)

That’s when the company decided to step in.

Rubio’s now offers a cheese taco shell for just 2g net carbs. It is a blend of mozzarella, Monterey Jack, and white cheddar cheese. They melt it on a hot flat grill until it becomes a crispy layer.

This means you can finally enjoy a proper taco without turning it into a salad bowl!

Rubio’s menu also includes cauliflower rice. It is a keto-friendly food that can satisfy all your rice cravings (minus the carbs!)

Their cauli rice is seasoned with citrus and cilantro. It makes for a perfect side dish with your keto-style cheese tacos.

And the best part is that it’s made with a non-starchy vegetable. As a result, a single serving of cauli rice contains just 2g net carbs.

If you make the right customizations, Rubio’s has plenty of keto-friendly options.

When I say keto-friendly, I’m talking about meals that are under 15g net carbs. This isn’t a magical number by any means. But I’ve accepted it as an ideal intake when dining out on keto.

See, there’s always a trade-off between the carbs and the food variety you can have. So whenever I’m dining out, I make sure it’s worth it.

Go below 10g carbs and you limit your options. Exceed 15g carbs and you can’t have anything for the rest of your day.

Hence, the 10-15g carb bracket fits just fine.
