Equipment

Ingredients

3 Tbsp coconut oil divided
16 oz / 450g white mushrooms sliced
2 large shallots sliced
3 Tbsp fresh rosemary leaves chopped
3 Tbsp garlic minced
Sea salt and black pepper to taste
3 lbs / 1.4kg beef tenderloin roast
1 large red onion sliced

Instructions

Pre-heat oven to 180C/350F/Gas 4.
Melt one tablespoon coconut oil in a large, high-sided skillet over medium heat. Add the mushroom and shallots and season with salt and black pepper, to taste. Cook, stirring occasionally until the mushrooms and shallots develop a bit of color and soften, approximately 4-5 minutes. Remove from heat and transfer to a bowl and set aside.
Melt the remaining coconut oil in a small bowl in a microwave. Add the rosemary and garlic to the coconut oil and season with salt and black pepper, to taste. Rub the rosemary-garlic mixture on top and all along the sides of the beef.
Arrange the sliced red onion on the bottom of the same skillet and place the seasoned beef tenderloin on top of the onions.
Arrange the mushroom and shallot mixture around the sides of the beef and place in the preheated oven for 45-50 minutes for medium-rare or longer for more well-done results.
Remove from oven and rest for 10-15 minutes before serving. Enjoy

Notes

Actual cooking time will vary depending on a number of factors, including the starting internal temperature of the beef. Therefore, allow the beef to rest at room temperature for 20-30 minutes before roasting and use an instant-read thermometer to check for doneness. For medium-rare, remove from oven at 60C/140F. The temperature will rise to 63C/145F as it rests.
