2 beef steaks
1 large onion, thinly sliced
2 tablespoons butter
1 tablespoon olive oil
Salt and black pepper, to taste
1/2 cup sour cream or garlic butter (optional for topping)
Fresh parsley, chopped (for garnish)
Directions
-
Season both sides of the steaks with salt and freshly ground black pepper. Let them rest at room temperature for 10 minutes.
-
Heat the olive oil in a skillet or grill pan over medium-high heat. Sear the steaks for 3–4 minutes per side for medium-rare, or longer if you prefer a different level of doneness. Remove the steaks from the pan and let them rest for 5 minutes.

In the same pan, reduce the heat to medium and add the butter. Once melted, add the sliced onions and cook slowly, stirring occasionally, until caramelized—about 10–15 minutes. The onions should be golden brown and soft.
-
Serve the steaks topped with the caramelized onions and a spoonful of sour cream or garlic butter, if desired.

Garnish with chopped fresh parsley and serve hot.

FAQs
What cut of steak works best for this recipe?
Ribeye, strip steak, or sirloin are excellent choices for tenderness and flavor.
How do I know when the steak is done?
Use a meat thermometer—130°F (54°C) for medium-rare, 140°F (60°C) for medium, and so on.
Can I grill the steak instead of pan-searing?
Yes, this recipe works equally well on a grill. Cook over high heat and rest before serving.
What’s the best way to caramelize onions?
Cook slowly over medium heat in butter, stirring occasionally, for 10–15 minutes until golden brown and soft.
Can I make the onions ahead of time?
Yes, caramelized onions can be made a day in advance and reheated.
What’s a good substitute for sour cream?
Garlic butter, crème fraîche, or even a herbed cream cheese can be used.
Can I use red onions instead of yellow?
Yes, red onions will caramelize slightly sweeter and add a deeper color.
Should I marinate the steak first?
It’s not necessary, but a simple marinade of olive oil, garlic, and herbs can enhance flavor.
Can I use ghee instead of butter?
Yes, ghee is a great alternative for caramelizing onions with a richer taste.
What sides go well with this dish?
Roasted vegetables, mashed potatoes, steamed asparagus, or a fresh green salad are all excellent pairings.
