Roasted Beef Tenderloin

You need this fancy recipe! Why? Because it’s so delicious and so easy. Roasted Beef Tenderloin is the perfect meal for a celebration. I marinate the tenderloin overnight to ensure a delicious flavor and sear it with mushrooms then finish it in the oven. The result is a perfectly cooked beef tenderloin that’s packed full of flavor. 

Why? Because it’s so easy! Oh my gosh I’m in love with this roasted beef tenderloin. It’s.so.fancy. but it’s really not. I mean…it is, like it looks fancy and tastes fancy, but it’s a no fuss recipe.

Marinate the meat, sear the meat, then roast the meat in the oven.

I can’t believe I’m saying this, buuuuuuut I think it’s kinda pretty. Right? I don’t love photographing meat…it’s just not all that photogenic but I think this is really beautiful. Maybe because it’s almost Christmas and everything looks amazing right now.

This is the perfect Christmas (I know it’s like in 4 days away) or New Year’s Eve recipe though! It’s a crowd pleaser, that’s for sure.

But don’t think you just need to make this for a special occasion. I made this on a weeknight for Vin and me with sweet potato fries. Uffff. It was delicious. And! an!d and!, guess what? I saved some for steak sandwiches the following night. You could also cut it up and throw it into a salad with blue cheese all over it.

Uffff again.

I roasted this bad boy up with some mushrooms, just throw them in the pan. The juices from the marinade will caramelize and make them taste like…like the best dang thing you’ve ever eaten. Vin was obsessed with the shrooms…they cook up so nicely with the tenderloin.

So…Christmas? Maybe New Year’s Eve? Or perhaps just a casual Wednesday night?

Do it.

Roasted Beef Tenderloin

Print

This simple roasted beef tenderloin recipe is so delicious. It's marinated in a salty and sweet marinade and served with caramelized mushrooms.

Prep Time 2 hours

Cook Time 20 minutes

Total Time 2 hours 20 minutes

Ingredients

• 1.5 pound beef tenderloin (you can get a larger one if needed)
• 1 container mushrooms (any kind will work)
• Olive oil for sautéing

Marinade

Toggle ingredient group

• 1/2 cup olive oil
• 2 teaspoons minced garlic
• 1/2 teaspoon black pepper
• 4 tablespoons light brown sugar
• 2 tablespoons soy sauce
• 2 heaping tablespoons dijon mustard
• 1 tablespoon chopped fresh rosemary

Instructions

1. The beef tenderloin marinates for 2 hours so when you are ready to roast, preheat oven to 450 degrees.
2. To make the marinade, mix all the ingredients in a bowl.
3. Place beef tenderloin in a zipper bag and pour marinade over top. Seal the bag and move beef around so that it’s completely covered. Place in refrigerator and marinate for at least 2 hours (overnight is even better).
4. When you’re ready to cook, take the beef out 30 minutes prior to cooking so it comes to room temperature. Pat dry with a towel to remove excess moisture.
5. Drizzle a little olive oil in an oven proof skillet (a cast iron skillet works well for this) and place over medium – medium/high heat for a few minute so the pan heats up. Add the beef tenderloin along with the mushrooms and sear the tenderloin on all sides so that it’s nicely browned, about 2 minutes per side.
6. Place the skillet into a preheated oven for about 12-15 minutes for medium doneness. If you’re using a larger tenderloin, it will most likely need to cook for a few additional minutes.
7. Let the tenderloin rest for 15 minutes before cutting into it. Serve with mushrooms and enjoy!

Notes

You will want to trim excess fat and tie the beef tenderloin with cooking twine so that it cooks evenly. You can do this yourself or you can have your grocery store butcher do this.

This recipe will serve 4-6 people depending on how much meat you want to serve. 4, 6 ounce filets, or 6, 4 ounce filets.
