Step 1: Preparing the Steak
- Season the Steak: Pat the steaks dry with a paper towel. Season both sides generously with salt and freshly ground black pepper. For more flavor, you can also rub minced garlic and thyme into the steak.
- Bring Steak to Room Temperature: Let the steak sit at room temperature for 20-30 minutes before cooking. This helps it cook more evenly.
Step 2: Caramelizing the Onions
- Heat the Pan: Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the sliced onions and a pinch of salt.
- Cook the Onions: Stir occasionally and cook the onions for 15-20 minutes, until they are soft and golden brown. For extra depth of flavor, add a teaspoon of balsamic vinegar during the last few minutes of cooking.
- Set Onions Aside: Once caramelized, transfer the onions to a plate and keep them warm.
Step 3: Cooking the Steak
- Heat the Skillet: In the same skillet, add 1 tablespoon of olive oil and 2 tablespoons of butter over medium-high heat. Allow the butter to melt and start to foam.
- Sear the Steaks: Once the pan is hot, add the steaks. Sear each side for 3-5 minutes, depending on your desired level of doneness (3 minutes per side for medium-rare). For thicker cuts, you may need to reduce the heat slightly after searing and cook for a few more minutes.
- Add Garlic and Thyme: During the last minute of cooking, add the minced garlic and fresh thyme (if using) to the pan. Baste the steaks with the butter for extra flavor.
- Rest the Steaks: Remove the steaks from the pan and let them rest for 5-10 minutes. This allows the juices to redistribute throughout the meat, ensuring a juicy bite.
Step 4: Bringing It All Together
- Serve the Steak: Once rested, slice the steak against the grain (if serving sliced) and top with the caramelized onions.
- Drizzle with Pan Juices: For added flavor, drizzle any remaining pan juices or a splash of Worcestershire sauce over the steak and onions.
5. Serving Suggestions
- With Mashed Potatoes: The creamy texture of mashed potatoes pairs beautifully with the rich steak and onions.
- Over Rice or with Crusty Bread: Serve the steak and onions over steamed rice or with crusty bread to soak up the delicious juices.
- Vegetable Sides: Add a side of roasted asparagus, green beans, or sautéed spinach for a complete meal.
6. Tips for the Perfect Steak
- Use a Meat Thermometer: For precise doneness, use a meat thermometer. Aim for 130°F (54°C) for medium-rare, 140°F (60°C) for medium, and 150°F (66°C) for medium-well.
- Let the Steak Rest: Always rest the steak after cooking to lock in the juices.
- Don’t Overcrowd the Pan: Cook the steaks in batches if needed to ensure a good sear and even cooking.
7. Variations and Customizations
- Mushroom and Onion Combo: Add sliced mushrooms to the onions for an earthy twist.
- Steak Marinade: Marinate the steak in a mixture of soy sauce, Worcestershire sauce, and garlic for a few hours before cooking for a deeper flavor.
- Spicy Kick: Add a pinch of red pepper flakes to the onions for a spicy edge.
8. FAQs and Storage Tips
- How Long Can I Store Leftovers? Store leftover steak and onions in an airtight container in the refrigerator for up to 3 days.
- Can I Freeze the Leftovers? Yes, freeze the steak for up to 2 months. Reheat gently to avoid drying out the meat.
