Aged Rib Eye With Onion Purée Recipes

Steps:

• For the onion confit: Heat a large enameled cast-iron pot over medium heat. Add the butter; when it begins to foam, add the red onions, marjoram, thyme, bay leaves and sugar, and sprinkle liberally with salt. When the onions begin to caramelize, add the red wine and balsamic vinegar and reduce to dry. Reduce the heat to medium-low and add 1 cup of the beef stock; cook until reduced to a glaze. Repeat until all the beef stock has been used. Turn off the heat and adjust the seasoning with salt and pepper.
• For the rib-eye: Heat a 12-inch cast-iron skillet over high heat; add the oil. Pat the steak dry with paper towels, and sprinkle liberally with salt and pepper. When the oil is just below smoking, place the steak into the pan. Once a nice sear has developed, flip the steak and add the butter, thyme and garlic. If the garlic or steak begins to burn, reduce the heat. Cook, basting the steak with the bubbling butter, until an internal temperature of 125 degrees F has been reached for medium-rare. Remove the steak to a cutting board and let rest for 7 to 10 minutes before slicing. Serve with the French onion confit.
• Place the potatoes in a large pot, cover with room temperature water and season liberally with salt. Bring to a boil over high heat. Reduce to a simmer and cook until fork tender. Drain the potatoes, saving 1/2 cup of the cooking water for thinning out if needed.
• Pass the potatoes through a food mill into a large bowl. Add the butter and heavy cream, and fold together with a spatula until combined. Fold in the shredded cheese. If the potatoes get too thick, thin them out with a little of the cooking water. Add salt and pepper to taste. Serve garnished with chives and a drizzle of olive oil.

Steps:

• Season steak generously with salt and pepper. Sprinkle with sliced garlic and rosemary and set aside to marinate, 20 to 30 minutes.
• Heat oven to 450 degrees. Meanwhile, bring a pot of well-salted water to a boil. Add potatoes and cook at a brisk simmer until just done, 10 to 15 minutes. Drain and keep warm.
• Heat a cast-iron or other heavy skillet over high heat. Remove and discard sliced garlic from steak. (If left on, it will burn in the skillet.)
• When pan is hot, put in the steak and let brown well on one side, 4 to 5 minutes. Wait until steak forms a crust and comes away cleanly from the bottom to move it.
• Flip steak and transfer pan to oven, uncovered. Roast until juices begin to rise on surface of steak (you will see the droplets) and internal temperature is 120 degrees, 8 to 10 minutes. Remove steak from pan and let rest, tented with foil, for 5 to 10 minutes. (Residual heat will continue to cook the meat to medium-rare as it rests.) Warm a serving bowl for the potatoes and plates for the steak.
• Melt butter in a wide skillet over medium-high heat. Add potatoes and toss to coat and heat through. Sprinkle with salt and pepper. Add minced garlic and cook, stirring, until softened but not browned, 1 minute or less. Gently stir in parsley and lemon zest and transfer to serving bowl.
• Cutting on a slight diagonal, slice steak into 1/2-inch slices, then transfer to plates. If using, place a handful of greens next to the steak. Serve immediately, passing potatoes at the table.
