For a simple dinner, this Cast Iron Ribeye Steak with Chimichurri Sauce is our go-to. Seared and basted with butter, the steak is then topped with a blended sherry, garlic, and caper chimichurri, and comes together in under 30 minutes.
Bring out your steak to room temperature for at least 30 minutes and season with salt and pepper.
In a high-speed blender or food processor, blend capers, caper brine, parsley, cilantro, garlic, chili flakes, olive oil, sherry vinegar, salt, and pepper until completely blended and smooth and fully emulsified.
Transfer to a deli container or an airtight container and transfer to the fridge until ready to serve.
Heat a cast-iron skillet or stainless steel pan over medium-high heat until very hot. Add neutral oil and carefully place the steak down. Sear for 3 to 4 minutes on each side, until a deep golden crust forms, and cook to medium-rare at 135 degrees using a meat thermometer.
Towards the 30 seconds, add butter and, using a big spoon, baste over your steak. Transfer your steak to a cutting board to rest for 5 to 10 minutes.
Slice against the grain, transfer to a serving platter, and serve with your chimichurri.

Notes
Instead of sherry vinegar for the chimichurri, you can use red wine vinegar or white wine vinegar.
How to Grill Ribeye Steak: If you want to grill your ribeye versus using a skillet, just follow all the same steps, but place it on your grill over direct heat using the same method as in the instructions.
Make sure you allow your steak to rest before slicing against the grain!
Storing: Store the chimichurri in the fridge up to 4 days.
