Ingredients

For the Seared Steak and Caramelized Onions:

• 2 ribeye steaks (or your preferred cut)
• Salt and pepper, to taste
• 2 tablespoons olive oil
• 1 tablespoon butter
• 1 large onion, thinly sliced
• 1 tablespoon brown sugar
• 1 tablespoon balsamic vinegar
• 1 cup beef broth
• 2 tablespoons heavy cream

For the Creamy Mashed Potatoes:

• 4 medium russet potatoes, peeled and cubed
• 4 tablespoons butter
• 1/2 cup milk (or as needed)
• Fresh parsley, finely chopped (for garnish)

Step-by-Step Preparation

Step 1: Prepare the Potatoes

Peel and cube the potatoes. Place them in a large pot, cover with water, and add a pinch of salt. Bring to a boil over medium-high heat and cook until tender (about 15–20 minutes). Drain and return to the pot.

Step 2: Cook the Mashed Potatoes

Mash the potatoes over low heat to let excess moisture escape. Add butter and milk gradually, mashing to your preferred consistency. Season with salt and pepper. Keep warm.

Step 3: Caramelize the Onions

In a large skillet over medium heat, heat olive oil and butter. Add sliced onions and sauté slowly for 15–20 minutes until golden brown. Stir occasionally. Add brown sugar and balsamic vinegar, stir, and remove from skillet.

Step 4: Sear the Steak

Season steaks with salt and pepper. In the same skillet, increase heat to high. Add more oil if needed. Sear steaks for 3–4 minutes per side (for medium-rare) or adjust for preferred doneness. Remove and let rest.

Step 5: Make the Pan Sauce

With the skillet over medium heat, deglaze with beef broth, scraping up browned bits. Simmer and reduce by half. Add heavy cream and let it thicken. Return caramelized onions and stir to coat.

Variations

• Herb-Infused Butter Steak: Add fresh rosemary or thyme while cooking the steak for an aromatic boost.
• Garlic Mashed Potatoes: Add roasted garlic for deeper, richer flavor in the mash.

Cooking Notes

• Let steaks come to room temperature before searing for even cooking.
• Avoid overcrowding the pan to ensure a proper crust forms on the steak.

Serving Suggestions

• Serve steak topped with caramelized onions and pan sauce.
• Plate with a generous scoop of creamy mashed potatoes.
• Garnish with freshly chopped parsley for color and brightness.
