Start by heating a large skillet over medium-high heat. Add 1 tablespoon of olive oil and 1 tablespoon of butter to get the base sizzling. This ensures your potatoes cook evenly and pick up great flavor.
Add sliced potatoes, garlic, thyme, rosemary, and oregano to the skillet. Cook for 3 minutes, stirring occasionally, then continue for another 3 minutes until lightly golden. The herbs infuse the potatoes with aromatic flavor.
Once cooked, transfer the potatoes to a plate and keep warm. This prevents them from overcooking while you sear the steak.
Turn the heat to high and add the remaining butter. Add steak cubes and sear for 1 minute, then stir until the steak is evenly browned. The high heat locks in juices and creates a delicious crust.
Return the potatoes to the skillet and toss with the steak. Finish with a sprinkle of fresh herbs and a bit more butter if desired. Serve immediately for the best taste and texture.
