Ingredients

Here’s what you’ll need to create this delightful dish (serving about 6):

For the Beef:
- 1 (3-4 pound) beef tenderloin, trimmed
- 2 tablespoons olive oil
- Salt and pepper to taste
- 2 tablespoons fresh rosemary, chopped (or 1 tablespoon dried)
- 2 tablespoons fresh thyme, chopped (or 1 tablespoon dried)
For the Au Jus:
- 2 large onions, thinly sliced
- 4 cups beef broth
- 1 tablespoon balsamic vinegar
- 1 teaspoon Worcestershire sauce
- Salt and pepper to taste

Cooking Steps

Ready to impress? Let’s get started!

Preheat Your Oven: Preheat your oven to 425°F (220°C). This is where the magic starts!
Prepare the Beef: Pat the beef tenderloin dry with paper towels—you want it to sear nicely. Rub the olive oil all over the tenderloin and season generously with salt, pepper, rosemary, and thyme.
Sear the Meat: Heat a large pan over medium-high heat. Sear the tenderloin on all sides, about 2-3 minutes per side until it gets that lovely brown crust. It’s like a lightning bolt of flavor!
Roast the Beef: Transfer the beef to a roasting pan and place it in the preheated oven. Cook until a meat thermometer inserted into the thickest part reads 135°F (for medium-rare), about 25-30 minutes. Adjust the time based on your preferred doneness.
Make the Au Jus: While your beef is roasting, let’s whip up that au jus! In the same pan you used for searing (don’t wash it yet—flavor overload!), add the sliced onions. Sauté them until they’re soft and golden brown, about 15 minutes. This is where the magic happens—what’s a great dish without great onions?!
Combine Everything: Add the beef broth to the skillet, scraping up any brown bits from the bottom. Stir in the balsamic vinegar and Worcestershire sauce. Let it simmer for about 10 minutes to meld those flavors.
Rest the Meat: Once your beef reaches the right temperature, take it out and let it rest for about 10 minutes. This helps the juices redistribute—no one likes a dry piece of meat!
Serve: Slice the beef tenderloin and serve it with the French onion au jus drizzled generously over the top. Your family may just start reinventing the dinner table as a restaurant after tasting this!

Cooking Tips

Don’t Rush the Searing: This step adds an incredible flavor. If the beef is eager to stick to the pan, just be patient—it’ll release once it’s nicely browned.
Leftover Love: If there are any leftovers (and that’s a big IF), store the beef in an airtight container in the fridge for up to 3 days for quick lunches or dinners—a beef sandwich, anyone?
Make It a Feast: Pair this dish with some roasted vegetables or creamy mashed potatoes for a full spread! You’ll feel like a top chef in no time, sipping wine while your family raves about your culinary skills.

FAQs

Can I substitute an ingredient in this recipe?
Absolutely! If you don’t have fresh herbs, you can use dried—but remember, dried herbs are more potent, so use about one-third of the amount.

How can I store leftovers?
Once cooled, place any leftovers in an airtight container in the fridge for up to three days. Reheat gently in the oven or on the stove with a splash of broth.
