The sizzle, the sear, the sheer joy of sharing—it’s all right here.

Recipe Overview

Prep Time: 10 minutes
Cook Time: 25 minutes
Total Time: 35 minutes
Servings: 4
Dietary Type: Gluten-Free (naturally)

Ingredients

4 tablespoons unsalted butter
2 tablespoons olive oil
2 large yellow onions, sliced
2 lbs boneless sirloin steaks
Salt and pepper to taste
1/2 cup Bourbon

Equipment Needed

Large skillet (cast iron preferred)
Serving platter

Instructions

In a large skillet, melt 2 tablespoons of unsalted butter with 1 tablespoon of olive oil over medium heat. The skillet should be large enough to accommodate the onions without overcrowding. Using a cast iron skillet will give you the best sear and heat distribution, but any heavy-bottomed skillet will work.
Add the sliced yellow onions to the skillet. Cook, stirring occasionally, until they are golden brown and caramelized, about 15 minutes. Patience is key here; don’t rush the process. The natural sugars in the onions need time to break down and create that deep, sweet flavour. If the onions start to burn, reduce the heat slightly.
Transfer the caramelized onions to a bowl and set aside. This prevents them from overcooking while you prepare the steak.
Season both sides of the boneless sirloin steaks generously with salt and pepper. Don’t be shy with the seasoning – it’s crucial for flavour. Press the seasoning into the meat to help it adhere.
Add the remaining 1 tablespoon of olive oil to the skillet. Increase the heat to medium-high. Once the oil is shimmering and hot, carefully place the seasoned steaks in the skillet.
Fry the steaks over medium-high heat, turning once, until browned to your liking. For medium doneness, cook for about 6 minutes per side. For medium-rare, aim for 4-5 minutes per side. Use a meat thermometer to ensure accuracy; 130-135°F (54-57°C) for medium-rare, 135-145°F (57-63°C) for medium. Remember that the steak will continue to cook slightly as it rests.
Transfer the cooked steaks to a serving platter and keep warm. Tenting the platter loosely with foil will help retain heat without making the steak soggy.
Pour the Bourbon into the hot skillet. Over medium heat, use a spatula to scrape up any browned bits that are clinging to the pan. These bits, called fond, are packed with flavour and will add depth to the sauce.
Allow the Bourbon to simmer and reduce by half, about 1 minute. This will concentrate the flavour of the Bourbon and burn off the alcohol. Be careful not to over-reduce, as the sauce can become too thick and syrupy.
Add the caramelized onions and the remaining 2 tablespoons of unsalted butter to the skillet. Stir until the butter is melted and incorporated into the sauce.
Reduce the heat to low and cook until the onions are heated through and tender, about 2 minutes. Season to taste with additional salt and pepper, if needed.
To serve, cut the steak into 1/4-inch thick slices against the grain. This ensures maximum tenderness. Top the sliced steak generously with the bourbon-glazed onions and serve immediately.

Expert Tips & Tricks

Pat the steak dry: Before seasoning and searing, pat the steak dry with paper towels. This helps to achieve a beautiful, brown crust.
Don’t overcrowd the pan: If your skillet isn’t large enough to accommodate both steaks without overcrowding, cook them in batches. Overcrowding lowers the temperature of the pan and prevents the steak from searing properly.
Let the steak rest: Allowing the steak to rest for 5-10 minutes after cooking is crucial. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavourful steak.
Use high-quality bourbon: While any bourbon will work, using a good-quality bourbon will significantly enhance the flavour of the sauce.
Consider adding a splash of beef broth to the bourbon sauce for added depth.
For extra richness, stir in a tablespoon of heavy cream or creme fraiche at the end.

Serving & Storage Suggestions

Serve the pan-seared steak and onions immediately for the best flavour and texture. Accompany it with roasted potatoes, steamed green beans, or a simple salad for a complete meal.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm the steak and onions in a skillet over low heat, or in the microwave. Be careful not to overcook the steak, as it can become dry. The sauce may thicken upon cooling; add a splash of water or beef broth to loosen it up during reheating. Freezing is not recommended as the steak’s texture will suffer.

Garlic Lovers: Add minced garlic to the skillet during the last minute of cooking the onions for a pungent kick.

FAQs (Frequently Asked Questions)

Q: Can I use a different type of onion?
A: While yellow onions are recommended for their sweetness when caramelized, you can substitute them with white or Vidalia onions. Red onions will also work, but will impart a slightly different flavour and colour to the dish.

Q: How do I know when the steak is cooked to my liking?
A: The best way to ensure your steak is cooked to the desired doneness is to use a meat thermometer. Insert the thermometer into the thickest part of the steak, avoiding bone.

Q: Can I make this dish ahead of time?
A: You can caramelize the onions ahead of time and store them in the refrigerator for up to 2 days. The steak is best cooked fresh, but can be seared ahead of time and finished in the oven just before serving.

Q: What if I don’t have bourbon?
A: If you don’t have bourbon on hand, you can substitute it with beef broth or apple juice for a non-alcoholic alternative. The flavour will be different, but still delicious.

Q: Can I use a different type of steak?
A: Absolutely! This recipe works well with other cuts of steak, such as ribeye, New York strip, or even flank steak. Just be sure to adjust the cooking time accordingly. Thicker cuts will require a longer cooking time.
