Ribeye Steak with Caramelized Onions and Mashed Potatoes: The Ultimate Comfort Dinner

Boil the Potatoes: Place the peeled and cubed potatoes in a large pot. Cover with water, add a pinch of salt, and bring to a boil over medium-high heat. Reduce the heat and simmer for 15-20 minutes, or until the potatoes are fork-tender.
Mash the Potatoes: Drain the potatoes and return them to the pot. Add the butter and cream, mashing until smooth and creamy. If you like garlic, add minced garlic at this stage and stir to combine. Season with salt and pepper to taste.
Keep Warm: Cover the mashed potatoes and set them aside, keeping them warm while you cook the steak and onions.
Step 2: Caramelize the Onions

Cook the Onions: In a large skillet, heat the butter and olive oil over medium-low heat. Add the sliced onions and a pinch of salt. Stir occasionally and cook for about 20-25 minutes until the onions are soft and golden brown.
Add Sugar and Vinegar: Stir in the brown sugar, and cook for an additional 5 minutes until the onions are deeply caramelized and sweet. Add the balsamic vinegar for extra depth of flavor, if desired.
Set Aside: Remove the onions from the skillet and set them aside, keeping them warm.
Step 3: Cook the Ribeye Steaks

Prepare the Steaks: Pat the ribeye steaks dry with paper towels and season both sides generously with salt and pepper.
Sear the Steaks: Heat the olive oil in a large skillet over medium-high heat. Once the oil is hot, add the steaks and cook for 4-5 minutes per side for medium-rare, or longer if you prefer your steaks more done.
Add Butter and Garlic: When the steaks are almost done, add the butter, crushed garlic, and rosemary (if using) to the skillet. Spoon the melted butter over the steaks as they finish cooking.
Rest the Steaks: Remove the steaks from the skillet and let them rest for 5-10 minutes before slicing. This ensures the juices stay locked in and the steak remains tender.
Step 4: Assemble and Serve

Plate the Dish: Serve the ribeye steak on a plate, topping it with a generous portion of caramelized onions.
Serve with Mashed Potatoes: Add a scoop of creamy mashed potatoes on the side. Garnish with chopped chives or parsley for a fresh touch.
Enjoy: Serve immediately while everything is warm and enjoy this comforting, hearty meal!
