Method
Season and sear the steak
- Season the steak cubes with salt and pepper.
- Heat a cast iron skillet over high heat until smoking, then sear the steak bites in a single layer without touching for 2 minutes per side until well browned.
- Work in batches and set the seared steak aside.
Make the cowboy butter and finish
- Reduce the heat to medium and add the butter to the skillet.
- Sauté the garlic and shallot for 1 minute, stirring often.
- Stir in the parsley, chives, Dijon mustard, lemon juice, red pepper flakes, and smoked paprika, then cook until fragrant and bubbling.
- Return the steak bites to the skillet and toss in the cowboy butter until coated, then serve immediately.
Notes
Pro tip: keep the skillet truly smoking for the first sear and don’t crowd the pan—browning happens faster when the cubes have contact. Refrigerate leftovers in an airtight container up to 3 days; reheat gently in a skillet over low heat to avoid overcooking. Freezing is not recommended because steak texture can soften after thawing. For a lighter option, use half butter plus olive oil, then finish with the same garlic-herb mixture.
