What’s Up, Hungry People

Weird recipe week continues here in the Starving Chef’s kitchen as I continue to cook my way through all the delicious, however unusual, ingredients I picked up a few weeks ago at Jungle Jim’s. Tonight’s dinner, we’re getting a little fancy with some black truffle butter and filet mignon.

Here’s What You Need

  • Filet mignon steaks: The main attraction, known for its tenderness and rich flavor.
  • Black truffle butter: Adds a luxurious, earthy flavor to elevate the steak.
  • Ghee: Used for frying, adds a nutty flavor and can withstand high cooking temperatures.
  • Olive oil: For caramelizing onions, offering a fruity note to the savory sweetness.
  • Onion: Adds sweetness and texture contrast when caramelized.
  • Salt and pepper: Basic seasonings to enhance the natural flavors of the steak.
  • Fresh parsley: Provides a fresh, herbaceous garnish to brighten the dish.
  • Garlic: Gives a pungent, spicy flavor that mellows when cooked, perfect for mashed potatoes.
  • Potatoes: The base for garlicky mashed potatoes, offering creaminess and comfort.

Let’s Cook!

Onions, in my humble opinion, go best with, well, everything! To achieve super nice and caramelized onions, I started those about an hour ahead at a low temperature to really get the onions super sweet and tangy, perfect for topping my filets.

While the filet mignon in this recipe might be the star of the show, it’s the black truffle butter that really sets it apart from every other steak I’ve ever cooked. At Jungle Jim’s, there’s a whole stand devoted to different butters from around the world.

While some of the more exotic butters sounded delicious, how often do I have the opportunity to cook with bona fide black truffles?

Not nearly enough, obviously! I’ve been scouring for more black truffle recipes that I can whip up on a Starving Chef budget – and I’m always open to suggestions from you, Hungry People!

For those seeking solid instructions on how to cook your steak to perfection, I’ve found some tips from my culinary mentor, Gordon Ramsay, who hands down has the best recipes for perfect steaks. He’s a genius when it comes to getting that flawless sear and juicy center.

In most cases, the rule of thumb is the more butter, the better. However, with truffle butter’s unique and pronounced flavor, a combination of half truffle butter and half clarified butter ensures the truffle taste shines through without overpowering the dish.

You’ll know your steak has reached perfection when it boasts a nice brown crust, yet the center remains tender and juicy. A prime filet mignon is ideally served rare to medium-rare. Venturing beyond that, you might as well choose a different dish, as you’re not savoring the full experience of a premium steak if it’s cooked well-done.

The rich, earthy flavor of the truffle butter melds beautifully with the sweetness of the caramelized onions and is brilliantly complemented by some garlicky potatoes. It’s a pity filet mignon tends to be on the pricier side; otherwise, I’d indulge in this luxurious dish every night…but hey, a little splurge now and then to pamper my expensive tastes is always worth it.

Black Truffle Butter Filet Mignon Tips

  • Choosing Your Steak: Opt for steaks that are at least 1.5 inches thick. This ensures a juicy center with a beautifully seared crust.
  • Achieving Perfect Caramelized Onions: Patience is key. Low and slow is the mantra for onions that are perfectly sweet and golden.
  • Using Ghee: Ghee’s high smoke point makes it ideal for searing steaks. It won’t burn as quickly as regular butter, giving you a perfect sear without the smoke alarm serenade.
  • Black Truffle Butter Magic: This is not just any butter. Its rich, earthy flavor makes every bite of steak a luxurious experience. Since it’s the star, let it shine but don’t overpower the dish.
  • Seasoning: Don’t be shy with salt and pepper. Proper seasoning brings out the meat’s natural flavors and complements the truffle butter.
  • Checking Doneness: Use a meat thermometer to ensure perfection without cutting into your steak. It’s the sneak peek that doesn’t ruin the surprise.
  • Letting It Rest: Allow your steak to rest for a few minutes after cooking. This lets the juices redistribute, ensuring every bite is as flavorful as the last.

Servings 2


  • 2 filet mignon
  • 3 tablespoons black truffle butter
  • 2 tablespoons ghee
  • 1 tablespoon olive oil
  • 1 onion chopped
  • salt & pepper to taste
  • fresh parsley for topping


  • OPTIONAL: Start by caramelizing the onions. Heat the olive oil over medium-low heat. Add the chopped onion and cook for 40 minutes, until the onions are caramelized and tender.
  • In a large skillet over high heat, melt the ghee until frothy and beginning to brown. Season the filets with salt and pepper, to taste.
  • Place the filets in the hot skillet and cook for 4-5 minutes per side, or until the internal temperature reaches 120°F for rare or 130°F for medium-rare. Lower the heat and add the truffle butter. Swirl the pan to mix the butters. Move the steaks to one side and tilt the pan so that the butters cover the steaks, or use a spoon to ladle the butter over the steaks, ensuring a golden brown crust forms.
  • Serve the filet mignon topped with the caramelized onions and on a bed of simple garlicky mashed potatoes. Garnish with parsley, as desired. Enjoy!
