Cast Iron Ribeye Steak served with a green herb sauce, will leave you with the feeling that this is the only steak recipe you will ever make again!

If you’ve never made a steak on a cast-iron grill before, then you really don’t know what you are missing. The heat from the grill not only sears the meat, but it cooks up a really juicy steak too.

I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions; to ensure that you have all the ingredients and equipment required, and to understand the steps and timings involved.

Ribeye steak is one of the tastiest and succulent cuts of steak. With a rich marbling of fat, this guarantees that the meat will be juicy and full of flavor.

The green sauce used in this recipe is similar to the popular Argentinian chimichurri sauce, made with fresh herbs, garlic, lemon, oil, and vinegar.

The perfectly cooked steak is sliced and served with the green herb sauce drizzled on top with your choice of sides. We’ve paired it simply with baby potatoes.

Ingredients & Equipment Used In This Recipe

While most ingredients can be bought in grocery stores, for your convenience, any specialized or notable ingredients (and equipment) needed for this recipe have been listed below and linked to Amazon or other stores if available online. The complete list of ingredients with measurements is found in the recipe card.

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. You can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).

Recipe Tips

  • The total cook time for this recipe will vary depending on a number of factors, including the internal starting temperature and thickness of the steaks, and the desired final cooking temperature.
  • For best results, remove the steaks from the refrigerator 30 minutes prior to cooking and use an instant-read thermometer to determine the level of doneness while cooking. As a rule of thumb, remove the steaks from heat when they are approximately 5 degrees below the desired final temperature.
  • It is very important to keep the cooking temperature high. If it’s too low, moisture escapes and makes the steak tough.
  • Do NOT turn the steak constantly which makes timing impossible to calculate – once is enough. Avoid pressing down on a steak as this expresses moisture.
  • Leave the steak to rest on a warm (not hot plate) for 3-5 minutes before enjoying. Resting the steak causes the juices to sink back into the meat making it more tender.
  • Here is a handy temperature chart for beef to use as a guideline.
  • The herb sauce in the recipe is blended until smooth rather than coarsely chopped in a traditional chimichurri. For a more traditional chimichurri-style sauce, briefly pulse the ingredients until just combined or finely chop them by hand for a less homogenous, but equally delicious, result.

  2. Heat a cast-iron grill over medium heat and brush the surface with half the remaining olive oil. Once the grill is hot, add the steaks. Brush with the remaining olive oil, and season with salt and black pepper, to taste.

  3. Cook steaks over medium heat for approximately 4-5 minutes before turning. Continue cooking for another 4-8 minutes, depending on how well you’d like the steaks done. Check the internal temperature with an instant-read thermometer after 4 minutes to determine the final cooking time.

  4. Remove from heat and allow the steaks to rest for 5 minutes.

  5. Slice to serve with a drizzle of the green sauce and your choice of sides. Enjoy!



*Or use 3 tablespoons fresh lemon juice. If using organic lemons, you can leave the rind on the lemon before processing in a high-powered blender. If not, remove the rind completely prior to using.
