Why You’ll Love This Pan-Seared Filet Mignon with Garlic Butter
- Restaurant-Quality at Home: That dramatic, golden-brown crust and a molten, buttery centre usually cost a fortune. Now you own the secret.
- Impressive Plating: A few deliberate garnishes and a glossy sauce transform a simple steak into a work of art that wows your guests.
- Surprisingly Quick: From fridge to plate in under 30 minutes, this feels like a grand gesture without the all-day kitchen slavery.
- Foolproof for Entertaining: With the right technique, you can nail the perfect medium-rare every single time, even with people watching.
- Customisable Elegance: The garlic butter base is a canvas for herbs, spices, or a cheeky splash of balsamic, letting you tailor it to your crowd.
Ingredients You’ll Need
- 2 filet mignon steaks, about 200g each, 4cm thick
- 2 tablespoons neutral oil (such as vegetable or rapeseed)
- Fine sea salt and freshly ground black pepper
- 3 tablespoons unsalted butter, softened
- 4 garlic cloves, minced
- 2 sprigs fresh thyme
- 1 sprig fresh rosemary
- 1 tablespoon chopped fresh parsley (for garnish)
- Flaky sea salt (for finishing)
Tip: For the best results, take your steaks out of the fridge 30 minutes before cooking to let them come to room temperature. This ensures even cooking and a perfect crust.
How to Make Pan-Seared Filet Mignon with Garlic Butter
- Prepare the steaks: Pat the filets dry with kitchen paper. Season generously on all sides with fine sea salt and black pepper. Let them sit on a plate while you heat the pan. The surface should feel dry to the touch, not tacky.
- Heat the pan: Place a large, heavy-based frying pan over a medium-high heat for a good 3-4 minutes. Add the neutral oil and swirl to coat. The oil should shimmer and ripple when you tilt the pan — a wisp of smoke is your cue that it’s ready.
- Sear the steaks: Carefully lay the steaks in the pan, away from you to avoid splatter. You’ll hear a fierce, satisfying sizzle. Cook for 3-4 minutes without moving them. The underside should be a deep, mahogany brown with a crisp edge.
- Flip and baste: Turn the steaks over using tongs. Add the butter, garlic, thyme, and rosemary to the pan. Tilt the pan slightly and use a spoon to baste the melting, foaming butter over the steaks for another 3-4 minutes. The air will be thick with the scent of toasted garlic and fragrant herbs.
- Check the temperature: Use an instant-read thermometer to check doneness. For medium-rare, aim for 52°C. For medium, 57°C. The steak should feel springy yet firm when pressed with your finger.
- Rest the steaks: Transfer the steaks to a cutting board or warm plate. Spoon any remaining garlic butter from the pan over the top. Let them rest, uncovered, for a full 5-7 minutes. You’ll see the juices settle and the internal temperature rise by a degree or two.
- Slice and serve: Slice the steaks against the grain into thick medallions, if you prefer, or serve whole. Sprinkle with flaky sea salt and fresh parsley.
Tips From My Kitchen
- Dry the steaks obsessively: Moisture is the enemy of a good crust. After testing this recipe five times, I finally got it just right by using extra kitchen paper to ensure the surface is bone-dry before seasoning. Any dampness creates steam, which steams the meat instead of searing it.
- Use a heavy pan: A cast-iron or heavy stainless-steel skillet retains heat far better than a non-stick one. This means the pan temperature doesn’t plummet when you add the cold steaks, giving you that immediate, aggressive sear.
- Don’t crowd the pan: If you’re cooking for four, use two pans or cook in batches. Overcrowding drops the pan’s temperature, causing the steaks to stew in their own juices rather than sear. They should have at least 2cm of space around them.
- Baste with purpose: The basting step isn’t just for show. The constant spooning of hot, foaming butter over the steak cooks the top gently while the bottom sears, ensuring an even cook and a flavourful crust. Tilt the pan so the butter pools, and spoon it over for a full minute.
- Resting is non-negotiable: If you cut into the steak immediately, all those precious juices will flood your cutting board. Resting allows the muscle fibres to relax and reabsorb the liquid, keeping the meat tender and moist. I always set a timer for exactly 7 minutes.
Equipment You’ll Need
- Large frying pan or skillet (cast-iron preferred)
- Sharp knife and cutting board
- Mixing bowls
- Wooden spoon or spatula
- Instant-read thermometer
- Tongs
Common Mistakes to Avoid
- Overcrowding the pan: When you crowd the pan, the steaks release moisture and the temperature drops. The meat ends up grey and tough instead of beautifully browned. Cook in batches if needed, and keep the first batch warm in a low oven.
- Wrong temperature: A pan that’s not hot enough will leave you with a sad, grey exterior. Medium-high heat is your friend. Use the shimmering oil and the first wisp of smoke as your visual cues. Conversely, don’t crank it to maximum or the butter will burn before the steak is done.
- Skipping the rest time: This is the most common mistake I see. Cutting into a steak straight from the pan releases a flood of juice, leaving the meat dry. Those 5-7 minutes of rest are what transform a good steak into a great one.
Delicious Variations to Try
- Spicy Version: Add a small, finely chopped red chilli or a teaspoon of smoked paprika to the garlic butter during the basting stage. The heat cuts through the richness beautifully and gives a lovely kick.
- Vegetarian/Vegan Option: Swap the filet for thick portobello mushroom caps or a block of firm, pressed tofu. Sear them in the same way, and use a vegan butter alternative with the garlic and herbs. The technique remains the same, and the result is just as satisfying.
- Different Protein: This method works a treat for thick pork loin steaks or lamb rump. Adjust the cooking time slightly; pork needs a few extra minutes to reach 63°C, while lamb is lovely at 55°C. The garlic butter compliments them all.

Frequently Asked Questions
Can I use a different cut of beef?
Absolutely, though you’ll need to adjust your cooking time. Rib-eye or sirloin work wonderfully, but they have more marbling and fat, so they’re slightly more forgiving. Just be sure to adjust your thermometer target based on the thickness of the steak.
How do I achieve a perfect medium-rare?
The only reliable way is with an instant-read thermometer. Remove the steak from the pan at 50°C, as the internal temperature will rise another 2-3°C during resting. This guarantees a warm, red centre without being raw.
Can I prepare the garlic butter in advance?
Yes, and I actually recommend it. Simply mash the softened butter with the minced garlic and chopped herbs, roll it into a log in cling film, and chill. Slice off a pat just before basting. It saves time and the flavours meld beautifully.
What if I don’t have a cast-iron skillet?
A heavy stainless-steel pan is your next best bet. Avoid non-stick pans if you can; they don’t retain heat as well and make it harder to get that deep crust. If you must use non-stick, preheat it thoroughly over a medium heat for longer.
How do I keep the steak warm while resting?
Rest the steak on a warm plate or a wire rack set over a baking tray. Tent it loosely with foil if you must, but leaving it uncovered preserves the crisp crust. A low oven at 80°C is fine for keeping the first batch warm while you cook the second.

Ensure steaks are patted very dry for a perfect sear. Use an instant-read thermometer for precise doneness. Resting the steaks is crucial for juiciness.
