Description

Perfectly seared ribeye steak paired with sweet, slow-cooked caramelized onions and creamy herb-infused mashed potatoes. This elegant yet comforting dish is ideal for special occasions or cozy weekend dinners, offering a harmonious blend of savory flavors and textures.


Ingredients

For the Steak and Onions:

  • 2 ribeye steaks
  • 1 tablespoon olive oil
  • 2 tablespoons butter
  • 2 large onions, thinly sliced
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon fresh thyme leaves

For the Herb Mashed Potatoes:

  • 2 lbs potatoes, peeled and cubed
  • 1/2 cup milk
  • 3 tablespoons butter
  • 2 tablespoons chopped fresh parsley
  • 1 tablespoon chopped chives
  • 1/2 teaspoon salt


Instructions

  1. Boil Potatoes: Place the peeled and cubed potatoes into a pot of salted water. Bring to a boil and cook for 15–20 minutes, or until the potatoes are tender when pierced with a fork. Drain the potatoes well.
  2. Mash Potatoes: In a large bowl, mash the drained potatoes with milk, butter, chopped parsley, chives, and salt until smooth and creamy. Set aside and keep warm.
  3. Caramelize Onions: Heat olive oil and 1 tablespoon of butter in a skillet over medium heat. Add the thinly sliced onions and cook for 12–15 minutes, stirring occasionally, until the onions become golden brown and caramelized. Remove from skillet and set aside.
  4. Season Steaks: While the onions caramelize, season both sides of the ribeye steaks with salt and black pepper evenly.
  5. Sear Steaks: In the same skillet used for the onions, add the remaining 1 tablespoon of butter over medium-high heat. Once melted and hot, add the steaks and sear for 3–5 minutes on each side, depending on your desired level of doneness.
  6. Plate and Serve: Once cooked, remove steaks from the skillet and let them rest for 5 minutes. Top each steak with the caramelized onions, sprinkle fresh thyme leaves over them, and serve alongside the creamy herb mashed potatoes.

Notes

  • Use Yukon Gold potatoes for extra creamy and smooth mashed potatoes.
  • Allow steaks to rest for 5 minutes before slicing to retain juices.
  • Add a splash of balsamic vinegar to the onions while caramelizing to enhance depth and sweetness.
