Bacon-Wrapped Filet Mignon with Whiskey Mushrooms & Caramelized Onions
Two thick filets, swaddled in Wright's thick-cut bacon and seared on every edge, paired with cremini mushrooms deglazed in Chattanooga Whiskey and onions coaxed slowly into deep amber sweetness. The dish you cook when you want to be remembered.
- 2 USDA Choice filet mignon steaks, 8 oz each, 1.5–2″ thick
- 4–6 strips Wright's thick-cut bacon (2–3 per steak)
- Kitchen twine or toothpicks to secure
- Kosher salt & coarsely cracked black pepper
- 1 tbsp avocado or grapeseed oil (high smoke point)
- 8 oz baby bella mushrooms, sliced
- 2–3 tbsp Chattanooga Whiskey
- 1 tbsp butter
- 1 large yellow onion, thinly sliced
- 1 tbsp butter
- Pinch of kosher salt
- 1 whole head of garlic, top sliced off
- 3–4 tbsp unsalted butter (for basting)
- 4–5 fresh thyme sprigs
- 10″ cast iron skillet
- Digital probe thermometer
- Tongs (never a fork)
- Optional: culinary torch
Heat the oven to 400°F. Slice the top off a whole head of garlic to expose the cloves, drizzle with oil, wrap loosely in foil, set it on the rack, and forget about it. Forty minutes from now you'll have roasted garlic that spreads like butter and tastes like a smoky cathedral. Start this first — everything else builds around it.
Melt 1 tbsp butter in a wide skillet over low-medium heat. Add the sliced onions and a pinch of salt. Stir occasionally — every few minutes is plenty. This takes 20 to 25 minutes and your patience will be tested. But burnt onions taste like failure, so stay the course. When they're deep amber and meltingly soft, pull them off and hold warm.
Pat the filets bone dry. Wrap each filet with thick-cut bacon — however many strips it takes to cover the perimeter with just a slight overlap. Secure with kitchen twine or toothpicks so the bacon stays put during the sear. Season the top and bottom of the medallions with salt and pepper — bacon brings its own salt, so be measured up top.
Heat 1 tbsp butter in your cast iron over medium-high. Add the sliced mushrooms in a single layer and let them sear, undisturbed, until golden — about 4 minutes. Toss, sear another minute. Pull the pan off the heat and add 2–3 tbsp Chattanooga Whiskey. You might see a brief flame as the alcohol ignites — that's normal. Reduce 30 seconds, then move the mushrooms to a warm plate.
Wipe the pan, return it to high heat, and let it get screaming hot — you should see wisps of smoke. Add the avocado oil. Lay the bacon-wrapped filets down and don't touch them. Sear 2:30 on the first side, flip, sear 2:30 on the second side. Then — and this matters — use your tongs to stand each filet on its bacon edge and roll slowly, about 30 seconds per rotation, until the bacon is crisp all the way around.
Drop the heat to medium. Add 3 tbsp butter, the thyme sprigs, and 2–3 cloves of the roasted garlic (squeezed from their skins, smashed into the foaming butter). Tilt the pan toward you and spoon the herb-garlic butter over the steaks for sixty full seconds. This is the moment the dish becomes restaurant-quality.
Transfer the entire pan to the 400°F oven. Probe thermometer in the thickest steak. For medium-rare, pull at internal 128°F — carryover will bring it to 130–135°F while it rests. For other doneness levels, see the Doneness by the Numbers table below.
Move the steaks to a warm plate, tent loosely with foil, and walk away. I know you want to cut into it immediately. Don't. This is a test of character. While they rest, plate the caramelized onions and whiskey mushrooms. Optional finishing touch: pass a culinary torch over the bacon for a final crackle right before serving — extra char, extra theater.
