Prep and Cook Time

Cooking: 10 minutes
Total Time: 20 minutes

Yield

Serves 2 generously

Difficulty Level

Easy to Medium

Ingredients

• 2 thin-cut beef steaks (such as flank, skirt, or flat iron, about 1/2-inch thick, 6-8 oz each)
• 2 large yellow onions, thinly sliced
• 2 tbsp unsalted butter
• 2 tbsp olive oil, divided
• 1 tsp kosher salt, plus more for finishing
• 1/2 tsp freshly ground black pepper
• 1/2 tsp smoked paprika (optional, for subtle warmth)
• 2 garlic cloves, smashed
• Fresh thyme sprigs for garnish
• Fresh lemon wedges for optional brightness

Instructions

1. Prepare the steak: Pat the thin steaks dry with paper towels to ensure a golden crust. Season both sides generously with kosher salt, black pepper, and smoked paprika. Let them rest at room temperature for 10 minutes to absorb the seasoning evenly.
2. Caramelize the onions: Heat 1 tablespoon of olive oil and 1 tablespoon of butter in a wide skillet over medium-low heat. Add the sliced yellow onions and a pinch of salt. Stir occasionally,allowing the onions to soften and turn a rich golden-brown,about 20-25 minutes. Stir more frequently towards the end to prevent burning. when caramelized, remove the onions and set aside, leaving the flavorful fond in the pan.
3. Pan-sear the steaks: Increase the heat to medium-high and add the remaining 1 tablespoon of olive oil to the skillet. When the oil shimmers and just starts to smoke, add the steaks along with the smashed garlic cloves. Avoid overcrowding; cook in batches if necessary.
4. Sear the steak for about 2 minutes on the first side without moving it, allowing a majestic crust to develop. Flip and sear the other side for an additional 1-2 minutes for medium-rare, adjusting time slightly for your preferred doneness.
5. Finish with butter and aromatics: Lower the heat to medium-low, add 1 tablespoon butter and a sprig of fresh thyme. Tilt the pan and spoon the melted butter over the steaks repeatedly for 30 seconds to enhance flavor and juiciness.
6. Remove steaks from the skillet and let them rest on a cutting board for 5 minutes. This allows the juices to redistribute,preserving tenderness.
7. Plate and garnish: Layer the caramelized onions generously over the steak or serve alongside. Garnish with fresh thyme sprigs and a squeeze of lemon for brightness if desired.

Tips for Success

• Choosing the cut: Opt for thin cuts like flank or flat iron, well-suited for speedy pan-searing to retain tenderness and juice.
• Dry steaks before cooking: Moisture is the enemy of browning; drying ensures a rich, crusty exterior.
• Use high smoke point oil: olive oil works well, but avocado or grapeseed oil are excellent alternatives for higher heat tolerance.
• Don’t overcrowd the pan: Crowding releases steam and prevents caramelization; sear steaks in batches if necessary.
• Rest the steak: Crucial to juicy results. Cutting to soon will release precious flavorful juices.
• Caramelizing onions: Low and slow is the key-rushing this step risks bitterness and uneven cooking.
• Make ahead: Caramelized onions keep well refrigerated for up to 3 days; reheat gently before serving.

Serving Suggestions

Slice the steak thinly against the grain and arrange on warm plates. Spoon the golden caramelized onions generously over or beside the steak for contrast in texture and flavor. Garnish with fresh thyme for an herbal note, and add a wedge of lemon for a clean citrus lift. Pair this dish with garlic mashed potatoes, grilled asparagus, or a crisp green salad to complete the meal beautifully.
