Horizon Farms



Please note that due to ever-increasing production and import costs the price of this product has been raised. We thank you for your understanding.

You get a whole of tenderloin filet roast, also known as the Chateaubriand. Choose between 500g (1.1lbs) and 1kg (2.2lbs). This is the same cut used for the famously expensive Chateaubriand, also the same part the filet mignon steaks are cut from. Our tenderloin filets roasts are perfectly trimmed and ready for a luxurious cooking experience right at home - specially made for festive occasions. The roast is lean and very fine-grained in texture. Cooked medium-rare the roast is incredibly tender - typical for cuts from the tenderloin.  There is nothing more tender than the tenderloin. Compared to the ribeye and striploin the tenderloin is much leaner, much more tender but less intensive in taste. For best results check our cooking instructions below.

Beef Tenderloin / Chateaubriand Roast Recipe Instructions

Chateaubriand Roast

Completely defrost the roast in the fridge. Heavily rub the roast with olive oil, high-quality sea salt, and freshly ground pepper. Optionally rub the roast with crushed garlic and thyme or rosemary. Cover the roast filet and store it in the fridge for a couple of hours. For maximum flavor store in the fridge for up to 24 hours - this is optional. Once out of the fridge make sure the roast reaches room temperature before you continue with the preparation.  

Chateaubriand Roast Searing

Prepare a skillet or fry pan with non-salted all-natural butter and make it hot. Really hot. Yes, turn on the range hood at full power, you'll need that. Sear all sides of the roast and make sure to create a crispy brown outside. Hear that sizzle? 

Searing Tenderloin Filet

Remember, we are not cooking the roast so make sure to flip often, keep basting with the juices to keep the outer layer juicy. Keep the searing under 5 minutes. Remove the roast and place it aside. 

Vegetables for Roasting

Have vegetables cut and prepared before you start the searing. Place the vegetables into a frying pan and add a cup of water. Cover with a lid and steam hard vegetables such as the potatoes, carrots, and zucchini on high heat for 10 minutes ahead as they take longer than the roast. 
 Chateaubriand Roast Vegetables

Place the Chateaubriand roast in the middle of the oven pan. Now add all the other vegetables such as baby onions, Brussel sprouts, broccoli, garlic cloves, mushrooms, asparagus, and mini tomatoes. To keep the vegetables moist place small cups and fill halfway with water. Now loosely cover the whole oven pan with aluminum foil. This will keep most of the moisture inside. 

Oven Roast

Preheat oven to 180 degrees Celsius or 350 degrees Fahrenheit and place the roasting pan in the middle. Set the timer to 30 minutes. Make sure to have a meat thermometer at hand as you need to check the internal temperature after 25 minutes.  


Roast Temperature

Check on the roast after the first 25 minutes and make sure the core temperature of the roast is 52 degrees Celsius or 125 degrees Fahrenheit before taking it out of the oven. If the roast is not ready after the timer has gone off - keep roasting. 

Resting Beef Roast

Let roast covered in the oven pan for another 10 minutes before slicing. It is still cooking on the inside and the core temperature will reach 55 degrees Celsius or 130 degrees Fahrenheit. Note that you can't really overcook the tenderloin as it is an extremely tender cut of beef that is very forgiving. For the tenderloin, we recommend medium-rare.

Sliced Roast Tenderloin

Slice the Chateaubriand roast in front of everybody for the wow effect. Make sure to use a large and sharp knife as the filet is very soft and wobbly and may, therefore, be difficult to cut.  

Sliced Chateaubriand Roast

Soft as butter. The tender eating experience of the Chateaubriand is unforgettable.  

Chateaubriand Candle Light

Sprinkle high-quality sea salt on the vegetables. Eat while still warm for soft and buttery flavor and experience. Serve with any full-bodied dry red wine that will perfectly complement this roast. Enjoy.
