How to Prepare Marinated Beef Tenderloin
Preparation Steps
Alright, let’s get started on this delicious journey! First things first, you’ll want to bring your beef tenderloin to room temperature. Just take it out of the fridge about 30 minutes before cooking. This little trick helps it cook evenly, which is super important for achieving that perfect juicy texture.
Next, you’ll tie the beef in three or four places. This isn’t just for looks; it helps the meat cook uniformly. Trust me, a nice, even thickness makes all the difference! Now, let’s whip up that marinade. In a large bowl or baking dish, combine the balsamic vinegar, olive oil, minced garlic, minced shallots, brown sugar, prepared horseradish, Dijon mustard, fresh thyme, rosemary, sea salt, and cracked black pepper. Whisk it all together until it’s well blended. The aroma is divine!
Marinating Process
Now, it’s time to marinate that beef! Place the beef tenderloin into the marinade, making sure it’s coated all over. Cover it with plastic wrap or a lid and pop it in the fridge. Ideally, let it marinate for at least 2 hours, but if you can swing it, leave it overnight for even more flavor. Just remember to turn the beef in the marinade once during that time to ensure every part gets that tasty goodness!
Cooking Instructions
When you’re ready to cook, preheat your oven to 425 degrees Fahrenheit (220 degrees Celsius). While the oven heats up, grab a small roasting dish and grease it lightly with some oil. Remove the beef from the marinade, letting any excess drip off before placing it in the prepared dish. Drizzle a few tablespoons of the marinade over the top—oh, this is where the magic happens!
Slide that beautiful beef into the oven and roast it for about 30 to 40 minutes. You’re looking for an internal temperature of 145 degrees Fahrenheit (63 degrees Celsius) for that juicy medium-rare. Once it’s done, let the beef rest, covered loosely with aluminum foil, for about 10 minutes. This step is crucial; it allows the juices to redistribute, making every slice a flavorful delight!

Tips for Success
To truly elevate your Marinated Beef Tenderloin, here are some pro tips that I swear by:
- Marinate Overnight: If you have the time, marinating the beef overnight is a game changer! It allows the flavors to penetrate deeper into the meat, making it even more delicious.
- Use a Meat Thermometer: For perfect doneness, invest in a meat thermometer. This way, you can avoid any guesswork and ensure your tenderloin is cooked just right.
- Let It Rest: Don’t skip the resting step! Letting the meat rest for about 10 minutes before slicing helps keep those flavorful juices locked in.
- Serve with Horseradish Sauce: A dollop of horseradish sauce on the side complements the beef beautifully and adds a nice kick!
- Pair with Sides: Consider serving it with roasted vegetables or a fresh salad to balance out the richness of the beef.
With these tips in your back pocket, you’ll be on your way to impressing everyone at your next gathering!
