Grilled Steak with Bourbon Peppercorn Sauce

A perfectly **grilled steak with bourbon sauce** is the kind of meal that makes everyone at the table go quiet for a second. The method here uses a reverse sear: you bring the steak up to temperature slowly in a low oven, then hit it with a ripping-hot cast iron sear for a crust that’s evenly browned edge to edge. While the steak rests, you make a bourbon peppercorn pan sauce right in the same skillet — flambé the liquor, scrape up the fond, finish with cold butter. The result is a steakhouse-quality dinner that takes about 45 minutes start to finish. This is the steak I cook every Father’s Day, and it has never let me down.

Why You’ll Love This Grilled Steak With Bourbon Sauce

• **Even edge-to-edge doneness** — The reverse sear method eliminates the gray band you get from stovetop searing. The interior hits 130°F uniformly before the final sear, so every bite is medium-rare.
• **A pan sauce that takes 4 minutes** — Instead of making sides, you use the fond left in the cast iron to build a glossy bourbon peppercorn sauce while the steak rests.
• **Works with any good ribeye** — You don’t need Wagyu. A Choice-grade ribeye, 1.5 inches thick, gives you the fat content and tenderness you need at a reasonable price.
• **The bourbon flambé is optional but worth it** — Lighting off the alcohol burns off the raw bite and leaves behind a caramelized sweetness that balances the cracked peppercorns.
• **One pan, no juggling** — The same cast iron goes from searing to sauce to table. Fewer dishes, better results.

Ingredients

• 1 pound (1.5 inches thick) bone-in ribeye steak (Choice grade works well. Pull from the fridge 45 minutes before cooking to take the chill off.)
• 1 teaspoon kosher salt (Diamond Crystal. If using Morton's, use 3/4 teaspoon — it's denser.)
• 2 tablespoons, plus more for finishing cracked black peppercorns (Crush them coarsely with the bottom of a pan or a mortar and pestle. You want visible fragments, not powder.)
• 1 tablespoon avocado or canola oil neutral oil (High smoke point matters for the cast iron sear. Do not use olive oil.)
• 1/3 cup bourbon (Any mid-shelf bourbon — Buffalo Trace, Woodford Reserve. Save the single malt for sipping.)
• 2 medium, finely diced (about 1/3 cup) shallots (Smaller dice so they cook through in the time you have.)
• 1/2 cup low-sodium beef broth (Better Than Bouillon roasted beef concentrate mixed with water works perfectly here.)
• 3 tablespoons, cubed cold unsalted butter (Cold butter emulsifies into the sauce and gives it body. Warm or melted butter will break the sauce.)
• 2 sprigs fresh thyme (Added to the sauce while it simmers. Discard before serving.)

Equipment

• Cast iron skillet (12-inch) — retains heat for a hard sear and goes from stovetop to oven safely
• Sheet pan with wire rack — for the reverse sear stage in the oven
• Instant-read thermometer — a Thermapen or similar probe is non-negotiable for hitting 130°F accurately
• Aluminum foil — for tenting the steak during its 8-minute rest
• Long lighter or kitchen torch — for flambéing the bourbon safely
• Small saucepan (optional) — if you want to pre-mix the bourbon and broth before adding to the pan

How to Make Grilled Steak With Bourbon Sauce

Step 1 — Reverse sear the steak (30-35 minutes)

Preheat the oven to 275°F. Season the ribeye generously on all sides with kosher salt. Place it on a wire rack set inside a sheet pan. Insert an instant-read thermometer probe into the thickest part of the steak, avoiding the bone. Cook until the internal temperature reaches 125°F for medium-rare (about 25-35 minutes depending on steak size). This slow bake renders the exterior fat gently and brings the interior to an even temperature. Pat the surface completely dry with paper towels before searing — any moisture will steam instead of sear.

Step 2 — Sear in cast iron (2-3 minutes)

Heat the cast iron skillet over high heat for 4 full minutes. Add the avocado oil. When the oil just begins to smoke, lay the steak away from you into the pan. Press down gently with tongs for the first 15 seconds to ensure full contact. Sear for 90 seconds without moving it. Flip and sear the second side for 60-90 seconds. For a thick crust, use a spoon to baste the steak with the pan drippings during the last 30 seconds of the second side. Transfer the steak back to the wire rack, tent loosely with foil, and rest for 8 minutes. The carryover heat will bring the internal temperature up to 130-132°F.

Step 3 — Build the bourbon peppercorn sauce (4-5 minutes)

Reduce heat to medium. Add the diced shallots to the same skillet and stir for 60 seconds until softened. Add the cracked peppercorns and toast for 30 seconds, stirring constantly. Remove the pan from heat, pour in the bourbon, and return to the burner. If cooking with gas, tilt the pan toward the flame to ignite the bourbon. If electric, use a long lighter. Let the flame subside naturally (about 30 seconds) — the alcohol burns off and leaves caramelized sweetness. Add the beef broth and thyme sprigs. Simmer until reduced by half, about 2-3 minutes.

Step 4 — Finish the sauce and plate (1 minute)

Reduce heat to low. Drop in the cold butter cubes one at a time, swirling the pan constantly with a spatula. The sauce will become glossy and thick enough to coat the back of a spoon. Remove the thyme sprigs. Taste and adjust salt — the pan drippings are already salty, so go easy. Slice the steak against the grain into 1/2-inch-thick pieces. Arrange on a warm plate and spoon the burgundy-colored sauce over the top. Finish with an extra crack of peppercorns.

Pro Tips

**Rest the steak, don’t skip it.** Cutting into a steak immediately after searing releases all the juice onto the board. The 8-minute rest lets the muscle fibers relax and reabsorb those juices. Cover loosely with foil so it stays warm.

**Pat the steak bone-dry before searing.** Even after the oven, the surface will have condensation. Moisture is the enemy of the Maillard reaction. Dry paper towels, dry crust.

**Use a thermometer, not the finger test.** For a 1.5-inch ribeye, timing alone is unreliable. Oven temperature variances, steak thickness, and starting temperature all shift the math. A $10 probe thermometer is the single best investment for cooking steak.

**Don’t crowd the pan with sauce ingredients.** Wait for the shallots to soften before adding the bourbon. Adding everything at once dilutes the fond and prevents proper caramelization.

**If the sauce breaks (looks greasy instead of glossy),** whisk in 1 teaspoon of cold water off the heat. This re-emulsifies the butter and brings it back together.

Variations & Substitutions

**H3: Mushroom Bourbon Sauce
Sauté 4 ounces of sliced cremini mushrooms in the pan before adding the shallots. Push them aside and follow the original sauce recipe. The mushrooms pick up the bourbon and broth and give the sauce an earthy depth. This is my go-to fall variation.

**H3: Blue Cheese Butter Finish
Skip the pan sauce entirely and top each slice of steak with a tablespoon of compound butter — 4 tablespoons softened unsalted butter mixed with 2 tablespoons crumbled blue cheese, 1 tablespoon chives, and a pinch of black pepper. Let it melt over the hot steak for a rich, tangy finish.

**H3: Coffee-Bourbon Rub
Mix 2 tablespoons finely ground coffee with 1 tablespoon cracked peppercorns, 1 tablespoon brown sugar, and 2 teaspoons kosher salt. Rub onto the steak 30 minutes before cooking. The coffee adds a dark, roasty bitterness that makes the bourbon sauce taste even better by contrast.

Storage & Reheating

Refrigerate leftover sliced steak in an airtight container with the bourbon sauce spooned over the top. The sauce congeals in the fridge — that’s the butter solidifying, and it’s perfectly fine. Eat within 3 days.

For the freezer, vacuum-seal or wrap the slices tightly in plastic wrap, then place in a freezer bag with as much air removed as possible. Freeze for up to 2 months. Thaw overnight in the fridge, not on the counter.

To reheat, bring the steak to room temperature for 20 minutes, then sear in a medium-hot pan for 60 seconds per side. For the sauce, warm it gently in a small saucepan over low heat, swirling in a teaspoon of cold water to re-emulsify. Microwave reheating works in a pinch but can toughen the steak, so keep the power at 50% and heat in 30-second bursts.

Frequently Asked Questions

Can I use a different cut of steak?

Yes, but adjust expectations. New York strip works well with the reverse sear and has less marbling — the sauce helps compensate. Filet mignon is too lean and mild; it benefits less from the bold bourbon sauce. Avoid thin cuts (under 1 inch) — they overcook before you can build a crust.

What if I don't want to flambé the bourbon?

Skip the lighter step entirely. Add the bourbon to the hot pan and let it simmer for 90 seconds before adding the broth. The raw alcohol taste won’t burn off completely, but the reduction concentrates the flavor enough that it’s barely noticeable. This is honestly what I do half the time.

Can I reverse sear on the grill instead of the oven?

Absolutely. Set up your grill for indirect heat at 275°F using a two-zone fire. Place the steak on the cool side with the lid closed. Use a probe thermometer to monitor internal temp. Then move it directly over the hot coals or burners for the sear. The smoke adds a bonus layer of flavor that you don’t get in the oven.

How do I know when my cast iron is hot enough?

Drop a few drops of water onto the dry pan. If they bead up and dance across the surface (the Leidenfrost effect), you’re above 350°F and ready to go. If they sit and evaporate slowly, wait another minute. If they steam instantly and disappear, it’s not hot enough yet.

My sauce is too thin. How do I fix it?

Simmer it an extra minute to reduce further. If it’s already thick enough in volume, remove the pan from heat and whisk in another tablespoon of cold butter — this thickens through emulsification, not reduction. Avoid adding flour or cornstarch; they dull the bright bourbon flavor.

This is the steak that turns a regular Friday into something worth remembering. The reverse sear gets you restaurant-quality doneness at home, and the bourbon peppercorn sauce takes four minutes and makes the whole plate taste like you spent an hour in the kitchen. Pair it with a [Bourbon Old Fashioned](/1303), put something simple on the side, and let the steak do the talking.
