Instructions (Step by Step)

Step 1: Preparing the Ribeye Steak

Bring the steak to room temperature – Remove the ribeye from the refrigerator 30 minutes before cooking to ensure even cooking.
Season the ribeye – Generously season both sides of the steak with salt and freshly ground black pepper. Optionally, you can apply a steak rub or seasoning blend.
Optional: Marinate the steak – For added flavor and tenderness, you can marinate the steak with olive oil, garlic, and herbs for up to an hour.

Step 2: Caramelizing the Onions

Slice the onions thinly – For even caramelization, slice the onions as thin as possible.
Cook low and slow – In a skillet, melt butter or heat olive oil over low heat. Add the sliced onions and cook slowly, stirring occasionally.
Season the onions – After about 10 minutes, season the onions with salt and pepper. Optionally, add a pinch of brown sugar or a splash of balsamic vinegar to speed up caramelization and enhance the flavor.
Cook until golden brown – Continue to cook the onions until they are deep golden and caramelized, about 30-40 minutes.

Step 3: Cooking the Ribeye Steak

Preheat the skillet – Heat a cast iron skillet over high heat until very hot.
Sear the steak – Add olive oil or butter to the hot skillet. Place the steak in the skillet and sear for 3-4 minutes per side, depending on the thickness, for a medium-rare cook.
Optional: Add garlic and herbs – During the last minute of cooking, add garlic cloves and fresh herbs to the pan for extra flavor.
Baste the steak – Tilt the skillet and use a spoon to baste the steak with the butter and juices in the pan.
Rest the steak – Remove the steak from the pan and allow it to rest for 5-10 minutes to let the juices redistribute.

Step 4: Making the Mashed Potatoes

Boil the potatoes – Peel the potatoes and cut them into chunks. Place them in a large pot of salted water and bring to a boil. Cook until tender, about 15-20 minutes.
Mash the potatoes – Drain the potatoes and return them to the pot. Add butter and milk or cream, and mash until smooth. For a creamier texture, use a potato ricer or an electric mixer.
Season to taste – Add salt, pepper, and roasted garlic if desired. Stir well and adjust seasoning if needed.
Optional garnish – Top with fresh parsley or chives for color and flavor.

Step 5: Bringing It All Together

Plate the steak – Place the ribeye steak on the plate and top with the caramelized onions.
Add the mashed potatoes – Serve a generous scoop of mashed potatoes alongside the steak.
Optional finishing touches – For added richness, drizzle the steak with a balsamic glaze or top with a compound butter.
