What is Beef Fillet?
Beef fillet, also known as tenderloin, is the softest cut of beef. It runs along the cow’s backbone, where the muscles do very little work. That’s why it’s melt-in-your-mouth tender. It’s the cut used for filet mignon, Beef Wellington, and elegant roasts. Because it’s lean, it cooks fast and pairs beautifully with sauces like this creamy Bearnaise.
Why You’ll Love This Recipe
This beef fillet recipe looks fancy but feels doable. The method is simple, the ingredients are few, and the result tastes like a restaurant dinner. The Easy Bearnaise sauce adds a silky, herby note that lifts the beef without overpowering it. It’s perfect for Christmas or any night you want something truly special.
Ingredient Overview
For the Beef Fillet
You’ll need 1.8kg of beef fillet (tenderloin), salt, and pepper. The salt draws out the natural flavor, and the pepper adds a sharp edge that balances the buttery sauce.
For the Easy Bearnaise Sauce
The sauce uses egg yolks, white wine vinegar, butter, and tarragon. The butter makes it velvety, the vinegar adds brightness, and the tarragon gives it that soft, aromatic kick. Together, they create a sauce that hugs every slice of beef.
How to Cook Beef Fillet (Step-by-Step)
1. Prepare the Beef
First, bring the beef fillet to room temperature. Trim the wider end so both pieces cook evenly. Then tie each with kitchen twine for shape and even roasting.
2. Sear for Flavor
Heat a cast iron skillet until it’s almost smoking. Sear the fillet on all sides until browned. This locks in the juices and gives that crave-worthy crust.
3. Roast to Perfection
Transfer the skillet to an oven at 200°C (400°F). For medium-rare, roast for 25 minutes until it reaches 55°C (130°F). For well done, go for 30 minutes and 60°C (140–145°F). Always use a meat thermometer to be sure.
4. Rest Before Slicing
Let the beef rest for 10–15 minutes. This helps the juices settle so every slice stays tender and juicy.
How to Make Easy Bearnaise Sauce
Melt the butter slowly, then skim off the white solids. In a small blender, mix egg yolks and vinegar until pale. Slowly pour in the warm butter while blending until thick and smooth. Stir in chopped tarragon and season with salt. Keep it warm, but don’t reheat it on high heat — it can split easily.
If it does split, whisk it gently or add a few drops of warm water to bring it back together.
Recipe Tips & Success Notes
Use a meat thermometer to hit the perfect doneness. Cut the fillet into two equal pieces before roasting so the thinner end doesn’t overcook. Sear and roast in the same pan if you can — a cast iron skillet works best. Rest before slicing for that juicy finish. And if your sauce separates, a quick whisk will fix it.
Serving Suggestions
This beef fillet pairs beautifully with Garlic Herb Roasted Potatoes, Carrots, and Zucchini – the perfect side for beef fillet. Add Crispy Pan-Fried Zucchini or lemon butter green beans for color. A spoonful of horseradish sauce is great for those who like a bit of heat. For a cozy pairing, try Creamy Broccoli Cheddar Soup to serve with roast beef.
Storage and Leftovers
This dish tastes best fresh, but you can store leftovers in an airtight container for 3–4 days in the fridge. Reheat gently in the microwave or a low oven to keep it moist. Avoid high heat to prevent dryness.

FAQs
How do I know when beef fillet is perfectly cooked?
Use a thermometer. Medium-rare is 55°C (130°F), medium is 57°C (135°F), and well done is around 60°C (140–145°F). Always rest before slicing for the best texture.
Can I make the Bearnaise sauce ahead of time?
Yes, but keep it warm, not hot. If it cools and thickens, whisk in a bit of warm water to loosen it before serving.
What’s the best pan for searing beef fillet?
A heavy cast iron or oven-safe skillet works best. It gives an even sear and can go straight into the oven.
