Ingredients for Truffle Butter Filet Mignon with Garlic Herb Mash

Here’s what you’ll need to create this mouthwatering dish (measurements are key – trust me, I’ve tested this so many times!):

• 2 (8 oz) filet mignon steaks – about 1½ inches thick for perfect searing
• 2 tbsp truffle butter – the star of the show!
• 1 tsp salt – I use kosher for even seasoning
• 1 tsp black pepper – freshly ground makes all the difference
• 2 tbsp olive oil – for that beautiful sear
• 2 large potatoes, peeled and cubed (Yukon Gold are my favorite for mash)
• 3 cloves garlic, minced – don’t skimp here!
• 2 tbsp butter – for ultra-creamy potatoes
• ¼ cup heavy cream – makes the mash dreamy
• 1 tbsp fresh parsley, chopped
• 1 tsp fresh thyme, chopped

Ingredient Notes and Substitutions

No fresh herbs? Use ⅓ the amount of dried (but fresh really is better!). For the truffle butter – splurge on the good stuff; it makes or breaks this dish. If you’re dairy-free, olive oil works for searing and coconut cream can sub for dairy in the mash (though it’ll change the flavor). And if you can’t find filet, ribeye works in a pinch – just adjust cooking time for the thicker cut.

How to Make Truffle Butter Filet Mignon with Garlic Herb Mash

Okay, let’s get cooking! This dish comes together surprisingly fast once you get going. I like to start the potatoes first since they take a bit longer, then multitask with the steaks. The key is having everything prepped and ready – trust me, when that steak is perfectly seared, you don’t want to be scrambling for ingredients!

Preparing the Filet Mignon

First, pat those beautiful steaks dry – this helps get that gorgeous crust. Season generously with salt and pepper on all sides. Heat your skillet screaming hot with olive oil until it shimmers. Carefully add the steaks (listen for that satisfying sizzle!) and don’t touch them for 4-5 minutes per side for perfect medium-rare. When they’re done, immediately top each with a glorious tablespoon of truffle butter and let them rest for 5 minutes – this is crucial for juicy results!

Making the Garlic Herb Mash

While the steaks cook, get those potatoes boiling in salted water until fork-tender (about 15 minutes). Drain well, then return to the pot. Add garlic, butter, cream, and half the herbs, then mash until smooth but still slightly chunky. Taste and adjust seasoning – I usually add another pinch of salt here. Stir in the remaining herbs right at the end for maximum freshness. So simple, yet so heavenly!

Tips for Perfect Truffle Butter Filet Mignon with Garlic Herb Mash

After making this dish more times than I can count, I’ve learned a few tricks that guarantee perfection every time. First – and this is non-negotiable – let your steaks sit at room temperature for about 30 minutes before cooking. Cold steaks won’t sear evenly, and nobody wants a gray exterior with a cold center!

Fresh herbs make all the difference in the mash – dried just can’t compete with that bright, vibrant flavor. And don’t be shy with the cream in your potatoes! Start with the measured amount, then add more by the tablespoon until you get that dreamy, cloud-like consistency. My grandma always said “mashed potatoes should barely hold their shape” – words to live by.

One last pro tip: warm your plates before serving. It keeps everything at the perfect temperature while you’re plating up this masterpiece.

Serving Suggestions for Truffle Butter Filet Mignon with Garlic Herb Mash

Oh, plating this beauty is half the fun! I love serving these steaks alongside simple roasted asparagus – the crisp-tender veg cuts through the richness perfectly. A bright arugula salad with lemon vinaigrette works wonders too. For wine? A buttery Chardonnay complements the truffle butter beautifully, or go bold with a Cabernet Sauvignon if you prefer red. Just don’t forget the crusty bread to swipe up every last bit of that truffle butter sauce!

Storage and Reheating Instructions

Leftovers? They rarely happen with this dish in my house, but if you’re lucky enough to have some, here’s how to keep them perfect. Store the steak and mash separately in airtight containers in the fridge for up to 2 days. When reheating, warm the steak gently in a low oven (275°F) for about 10 minutes – any hotter and it’ll overcook. The mash? A quick zap in the microwave with a splash of cream brings it right back to creamy deliciousness. Pro tip: the truffle butter flavor actually deepens overnight!

Frequently Asked Questions

Q: How do I adjust cooking time for different steak doneness?
For rare, aim for 3-4 minutes per side; medium needs 5-6 minutes. Use a meat thermometer – 125°F for rare, 135°F medium-rare, 145°F medium. Just remember the steak keeps cooking while resting!

Q: What if I can’t find truffle butter?
No panic! Mix 2 tbsp softened butter with ½ tsp truffle oil. It won’t be quite the same, but still delicious. Or try compound butter with minced shallots and herbs for a different twist.

Q: Can I prep anything ahead?
Absolutely! Peel and cube potatoes hours before; keep them in water. Mix herbs for the mash too. But sear steaks fresh – they only take minutes anyway. The truffle butter topping must happen right before serving!

Q: My mash seems gluey – help!
Overmashing releases too much starch. Use a potato ricer or hand-masher, not a food processor. And always warm your cream before adding – cold dairy makes potatoes gummy.

Q: Can I use a different steak cut?
Filet’s tenderness is ideal, but ribeye works (adjust thickness/time). Avoid lean cuts like sirloin – they won’t stand up to the rich truffle butter as beautifully.
