Paleo Korean Flank Steak (Whole30, Keto)

4 minute read

Paleo Korean flank steak is a delectable and whole food dish that beautifully blends the vibrant flavors of Korean culinary traditions while keeping with a Paleo diet. I like to marinate the steak the day before to intensify the rich umami flavors, however, you can marinate it the same day and still enjoy that crave-able combination of savory and sweet flavors. This simple, weeknight worthy dish pairs perfectly with a quick and spicy Korean cucumber salad or a crisp and colorful Asian slaw.

One of my favorite beef dishes growing up was bulgogi, and this marinated Korean steak is spot on. This is one of my favorite recipes for Korean barbecue because it is so easy and boasts all the delicious flavors without all the work. I prefer my steak on the medium-rare side, so a flank steak is perfect for getting a tender, juicy, and mouthwatering bite!

Why Grass-Fed Beef vs. Conventional

Let’s first talk about why I prefer grass-fed beef over grass-finished and conventional beef. In their natural habitat, cows eat grass and small amounts of grain when the grass is seeding [1]. This provides the cow all the nutrients it needs to healthy, and we want to eat healthy animals. When cow are fed a lot of grain, like in conventional beef, the food source is not the natural source of food for the cows and it lacks the nutrients the cow needs to stay healthy, thus creating a less nutritious beef.

Additionally, because grass-fed cows are eating what they are supposed to be eating, the beef they produce is the most nutrient dense and has the omega-3’s that are supposed to naturally be in the beef. Due to the lack of nutrients in conventional beef, it does not contain the omega-3’s thus creating a nutrient deficient beef.

Grass-fed beef is not necessarily the same as grass-finished beef, so make sure you ask your butcher or the farm you source your beef from to clarify. Ideally you want beef sourced from an animal that grazed on grass its entire life, however there are farms that grain-feed most of the life and then “finish” on grass, or even grass feed most of the life and “grain-finish” to fatten the animal up in the last few months. As mentioned before, 100% grass-fed beef is the most nutrient dense beef and is my preferred choice when eating any beef nose to tail.

Grass-fed beef is loaded with nutrients such as protein, fat, vitamins and minerals.

  • Protein is an essential nutrient and beef is a complete source of all essential amino acids you need. Amino acids are the building blocks to the proteins in your body, including collagen, and they are necessary in cellular health and repair.
  • Over one third of the fat found in beef is oleic acid, the same monounsaturated fat that is also found in avocado oil and extra virgin olive oil. Oleic acid supports brain and nervous system function and support healthy blood sugar regulation [2].
  • Vitamins: B3 (niacin: support healthy blood fat levels and blood sugars ), B6 (supports a healthy immune system), B12 (essential vitamin necessary in red blood cell formation.)
  • Minerals:
    • Iron: Heme iron that is easily absorbed and is necessary in the formation of hemoglobin.
    • Phosphorus: Supports healthy teeth and bones, muscle recovery after working out, and detoxification.
    • Selenium: Supports thyroid health [3] and supports your immune system.
    • Zinc: Essential in digestion, thyroid health, and a healthy immune system.

So grab some 100% grass-fed beef and let’s get cooking!
