Best Keto Low-Carb Beef And Broccoli Recipe

If you are venturing into a low-carb, ketogenic lifestyle, you are probably looking for a recipe that has super low carbs and a sufficient amount of protein. Something that is also easy to prepare, great for meal prep, yet tastes delicious.

Beef and broccoli are perfect ingredients for this type of healthy, low-carb recipe. One is rich, meaty, and fatty, and the other one is, well, broccoli. Still, together they’re greater than their sum — they’re a match made in low-carb heaven.

Chinese American cuisine wouldn’t be the same without this colorful and sticky dish. And I say Chinese American because this staple dish was born in the USA, in the hands of Chinese immigrants!

So, how did beef and broccoli come to be? Most importantly, is there a way to make healthier low-carb beef and broccoli?

The History of Beef and Broccoli

Although similar dishes exist in China, beef and broccoli are 100% made in the USA. Broccoli, as we know it, is not a thing in the big Asian country, and pork is much more common than beef in China.

Still, stir-frying meat and veggies on a blistering wok is very much a Chinese cooking technique, and so is cooking the food with a tasty brown sauce. 

Chinese broccoli, or gai-lan, is leafier than the Mediterranean broccoli we all know. Although the first Chinese restaurants in America opened their doors during the California Goldrush in the mid-1850s, beef and broccoli didn’t appear until Italian immigrants popularized broccoli in the States around the 1920s. That makes the dish around 100 years old! That’s a classic!

What Goes Into Beef and Broccoli?

Beef and broccoli is a deliciously uncomplicated dish. You need beef, most commonly flank steak (or flat iron steak or sirloin steak), and broccoli. Long-stemmed Broccolini or Broccolette works great as well.

The secret behind this delicious meal is the marinade, as flank steak needs tenderizing before cooking. Marinating the meat with garlic, ginger, soy sauce, and black rice vinegar (or white rice vinegar) guarantees tender, flavorful meat.

Fish sauce and toasted sesame oil give the dish umami flavors and intensity, becoming that delicious brown glaze that makes beef and broccoli special. And since we’re aiming at a keto, low-carb beef, and broccoli, we’re keeping out the sugar and cornstarch.

Here’s a healthy version of beef and broccoli that aligns with keto and other low-carb diets.

What To Serve With Low-Carb Beef And Broccoli?

Broccoli and beef are a classic pairing that doesn’t really need a side dish. However, if you do want to add a side dish to serve with them but to keep carbs minimal then it can be a challenge. However, there are a few low-carb rice substitutes that you can use in place of traditional white rice. Some of the most popular substitutes include cauliflower rice, mushroom rice, lentils, and Shirataki rice. These substitutes are easy to prepare and can be used as keto-friendly side dishes for beef and broccoli.

How To Store Beef And Broccoli

The leftover beef and broccoli is best stored in the refrigerator in a sealed, airtight container or a Tupperware box. It will last for about three to four days in the fridge. To further increase the shelf life of beef with broccoli, store it in the freezer for up to two months.

Is Beef And Broccoli Gluten-Free?

Beef and broccoli recipes often include soy sauce and most soy sauces are usually made with soybeans and wheat, which means that most soy sauces are not gluten-free and therefore the whole recipe will contain some gluten. To make this dish gluten-free, use Tamari (Japanese soy sauce) which is made by fermenting soybeans and is usually gluten-free.
