This recipe pairs succulent beef fillets with the flavors of garlic, mustard, olives, and capers, delivering a delightful culinary experience.
Ingredients:
Instructions:
- Take the butter out of the fridge to let it soften.
- Mince the garlic cloves.
- Finely chop the olives and capers.
- Peel and cut the potatoes into even chunks.
- In a small bowl, combine the softened butter, minced garlic, mustard, chopped olives, and capers.
- Add the lemon juice and mix well until all ingredients are evenly incorporated.
- Transfer the mixture onto a piece of parchment paper and roll it into a log. Place it in the refrigerator to firm up while you prepare the rest of the meal.
- Place the potato chunks in a large pot and cover with cold, salted water.
- Bring to a boil over medium-high heat and cook until tender, about 15-20 minutes.
- Drain the potatoes and return them to the pot. Let them sit for a minute to allow excess moisture to evaporate.
- In the pot with the drained potatoes, add the sour cream and olive oil.
- Mash the potatoes until smooth and creamy. Season with salt and pepper to taste. Keep warm.
- Preheat a grill or large skillet over medium-high heat.
- Season the beef fillets with salt and pepper on both sides.
- Add a little olive oil to the skillet if using, and cook the fillets for about 4-6 minutes on each side, depending on your desired doneness (use a meat thermometer for precision: 125°F for rare, 135°F for medium-rare, 145°F for medium, 155°F for medium-well, and 160°F for well-done).
- Place a generous spoonful of olive oil mash onto each plate.
- Lay the cooked beef fillet on top of the mash.
- Slice the chilled lemon-thyme butter into rounds and place a round on top of each fillet to melt slightly from the heat of the steak.
- Garnish with a sprinkle of fresh thyme or parsley if desired.
Tips:
- Choose high-quality beef fillets.: Invest in good quality, tender beef fillets for the best results.
- Let the butter soften naturally.: Let the butter come to room temperature before mixing it with other ingredients for a smoother consistency.
- Use a meat thermometer.: To achieve the perfect level of doneness, use a meat thermometer to ensure the fillets are cooked to your desired temperature.
- Season well.: Don't skimp on seasoning both the meat and the potatoes to bring out the full range of flavors.
- Let the steak rest.: After cooking, let the steak rest for a few minutes to allow the juices to redistribute, ensuring a juicy and tender bite.
- Blend the olives well.: For a smoother olive oil mash, make sure to finely chop or blend the olives before incorporating them.
The combination of the tender, juicy fillet steak and the rich, creamy olive oil mash creates a dish that is both sophisticated and comforting. Adding the vibrant lemon-thyme butter elevates the flavor profile, making it a memorable meal perfect for any special occasion.
