How Long to Cook Beef Tenderloin Roasts

Keep in mind that beef tenderloin cooking times can vary slightly depending on your oven. The best, and only consistent, reliable way to know you’ve cooked your beef tenderloin to the desired doneness is to use a meat thermometer. Insert an oven-going meat thermometer into the thickest part of the roast. When the thermometer reads 135°F, your roast will be medium after resting, which is ideal.

Remove your tenderloin from the oven when the thermometer is 5-10°F lower than your desired doneness.

Rare 120 – 125 degrees F
Medium Rare 130 – 135 degrees
Medium 140 – 145 degrees F
Medium Well 150 – 155 degrees F
Well Done 160 + degrees F

How to Make a Perfect Rosemary Garlic Beef Tenderloin Roast

Yields: 6 Servings | Prep time: 10 mins | Cook time: 45-50 mins

Ingredients:

3 T. Butter, divided
16 oz. white mushrooms, sliced
2 large shallots, sliced
3 T. fresh rosemary leaves, chopped
3 T. garlic, minced
Sea salt and black pepper, to taste
3 lbs. beef tenderloin roast
1 large red onion, sliced

Directions:

Place oven rack in center position and pre-heat oven to 350°F.

Melt one tablespoon butter 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 butter in a small bowl in a microwave. Add the rosemary and garlic to the butter 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 pre-heated oven for 45-50 minutes for medium-rare. Test with a meat thermometer, ideally beef tenderloin should be cooked to 130 to 135 degrees F.

Remove from oven and rest for 10-15 minutes before serving. Enjoy!
