Ingredients:

For the Steak:

  • 4 beef steaks (ribeye, sirloin, or filet mignon)
  • Salt and black pepper, to taste
  • 2 tablespoons olive oil or butter

For the Red Wine Sauce:

  • 1 cup red wine (such as Cabernet Sauvignon or Merlot)
  • 1 cup beef broth
  • 1 tablespoon balsamic vinegar (optional, for added depth)
  • 1 tablespoon tomato paste
  • 2 cloves garlic, minced
  • 1 teaspoon dried thyme (or 1 tablespoon fresh thyme leaves)
  • 1 tablespoon butter
  • 1 teaspoon cornstarch mixed with 2 teaspoons water (optional, for thickening)

For the Caramelized Onions:

  • 2 large onions, thinly sliced
  • 2 tablespoons butter or olive oil
  • 1 tablespoon balsamic vinegar or sugar (optional, for sweetness)
  • Salt, to taste

For the Mashed Potatoes:

  • 4 large potatoes, peeled and cut into chunks
  • 1/2 cup milk or cream (adjust based on desired consistency)
  • 4 tablespoons butter
  • Salt and black pepper, to taste

Instructions:

1. Prepare the Mashed Potatoes:

  • Place the peeled and chopped potatoes in a large 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 and return them to the pot.
  • Add the butter and milk (or cream) to the potatoes and mash until smooth. Adjust the amount of milk based on your preferred consistency.
  • Season with salt and black pepper to taste. Cover and keep warm.

2. Caramelize the Onions:

  • In a large skillet, melt 2 tablespoons of butter (or olive oil) over medium heat.
  • Add the sliced onions and a pinch of salt. Cook, stirring occasionally, for 20-30 minutes until the onions are soft, golden, and caramelized.
  • If you prefer a sweeter flavor, stir in 1 tablespoon of balsamic vinegar or sugar during the last few minutes of cooking.
  • Once caramelized, remove from heat and set aside.

3. Cook the Steaks:

  • Season the steaks generously with salt and black pepper on both sides.
  • In a large skillet or grill pan, heat 2 tablespoons of olive oil or butter over medium-high heat.
  • Add the steaks to the hot pan and cook to your desired level of doneness:
    • Rare: 2-3 minutes per side (internal temperature of 125°F/52°C)
    • Medium-Rare: 4-5 minutes per side (internal temperature of 135°F/57°C)
    • Medium: 6-7 minutes per side (internal temperature of 145°F/63°C)
  • Once cooked, transfer the steaks to a plate, cover with foil, and let them rest while you prepare the sauce.

4. Make the Red Wine Sauce:

  • In the same pan you cooked the steaks, add the minced garlic and cook for 1 minute until fragrant.
  • Stir in the tomato paste and cook for another minute.
  • Pour in the red wine and balsamic vinegar (if using), scraping up any browned bits from the bottom of the pan.
  • Bring the wine to a simmer and cook until it reduces by about half, approximately 5-7 minutes.
  • Add the beef broth and thyme, and continue to simmer for another 5 minutes until the sauce thickens slightly.
  • If you prefer a thicker sauce, mix 1 teaspoon of cornstarch with 2 teaspoons of water and stir it into the sauce. Cook for another 2-3 minutes until thickened.
  • Stir in 1 tablespoon of butter to finish the sauce, adding richness and shine.
  • Taste and adjust seasoning with salt and pepper if needed.

5. Assemble the Dish:

  • Plate the mashed potatoes, then place the steak on top or beside the potatoes.
  • Spoon the red wine sauce generously over the steak.
  • Top with the caramelized onions for a delicious finishing touch.

6. Serve:

  • Serve the dish hot, alongside your favorite vegetables, such as sautéed spinach or roasted asparagus.
