Servings: 6 Total Time: 2 hrs 25 mins Difficulty: Intermediate

Easy slow-roasted beef tenderloin is a showstopper on its own, but when paired with the right sides, it becomes a truly unforgettable meal. 

Creamy mashed potatoes are an ideal companion; their buttery richness complements the beef’s robust flavor, creating a perfect balance. Roasted vegetables, like carrots, Brussels sprouts, and asparagus tossed in olive oil and sea salt, add texture and a slight sweetness that enhance the tenderloin’s savory profile.

A fresh arugula salad with a light vinaigrette brings a refreshing contrast, offering a crisp bite to balance the richness of the beef. For an indulgent touch, garlic bread is an irresistible choice. The toasted bread, slathered in garlic butter, is perfect for mopping up those delicious beef juices. 

And to round it all off, a glass of red wine, like a smooth Pinot Noir or a bold Cabernet Sauvignon, elevates the flavors of the tenderloin, making each bite even more enjoyable. These pairings create a harmonious and elevated dining experience that complements the slow-roasted beef tenderloin beautifully.

Step by Step Directions

Step 1: Preheat Your Oven

Begin by preheating your oven to 250°F (120°C). A lower temperature is key for that melt-in-your-mouth texture.

Step 2: Prepare the Beef Tenderloin

Trim any excess fat from the beef tenderloin. This not only prevents flare-ups in the oven but also ensures the beef doesn’t turn greasy. Season generously with kosher salt and black pepper to enhance flavor.

Step 3: Sear the Beef

In a large skillet or cast-iron pan, heat 2 tablespoons of ghee over medium-high heat. Once melted, add the tenderloin. Sear on all sides until golden brown, about 2-3 minutes per side. This step is crucial as it locks in juices and adds depth of flavor.

Step 4: Add Shallots and Rosemary

Once the tenderloin is seared, remove it from the heat. Add the chopped shallots and rosemary sprigs around the beef in the skillet. The shallots will cook and impart sweet flavor during roasting.

Step 5: Coat with Mustard and Ghee

Brush the tenderloin with Dijon mustard, then drizzle the remaining ghee over it. This not only enhances the taste but also helps create a lovely crust.

Step 6: Roast in the Oven

Transfer the skillet to the preheated oven. Roast the beef tenderloin slowly until it reaches an internal temperature of 125°F (52°C) for medium-rare. This usually takes about 1 to 1.5 hours, depending on the thickness of the meat.

Step 7: Rest the Meat

After roasting, remove the beef from the oven and allow it to rest for at least 15-20 minutes. Resting is vital; it helps redistribute the juices, ensuring each bite is juicy and tender.

Step 8: Slice and Serve

When ready, slice the tenderloin into medallions. Serve this delicious roast with flaked sea salt, freshly chopped tarragon, and your homemade horseradish cream sauce.

Tips on Making Easy Slow Roasted Beef Tenderloin

  • Choose the Right Cut: Selecting a good quality center-cut beef tenderloin ensures better flavor and texture.
  • Use a Meat Thermometer: Avoid overcooking by keeping an eye on the internal temperature.
  • Low and Slow: Resist the urge to crank the heat; patience is your friend for this recipe.
  • Resting is Key: Always let the meat rest before slicing to maintain moisture.
  • Experiment with Flavors: Incorporate different herbs like thyme or garlic for variety.

How Do You Store This Easy Slow Roasted Beef Tenderloin?

If you have leftovers (which is rare, but it happens!), here’s how to store them:

  1. Cool Completely: Allow the beef to cool down to room temperature before storing.
  2. Wrap Tightly: Use plastic wrap or aluminum foil to wrap slices tightly. You want to minimize air exposure to prevent drying out.
  3. Refrigerate: Keep it in the fridge and consume within 3-4 days.
  4. Reheat Gently: To warm, place in an oven preheated to 250°F (120°C) until heated through without compromising texture.

What Other Substitutes Can You Use in Easy Slow Roasted Beef Tenderloin?

If you’re looking to get creative or make adjustments, consider these options:

  • Pork Tenderloin: Great alternative with similar cooking methods, though it has a milder flavor.
  • Lamb Loin: Offers a unique taste; just adjust seasoning to complement the meat.
  • Chicken Breast: Use boneless, skinless chicken breasts. Keep cooking time in check to avoid dryness.
  • Plant-Based Options: Portobello mushrooms can offer a hearty, meaty texture for vegetarians.
  • Roast Beef: Use a cheaper cut like chuck or round. Just be prepared for a different cooking time and resulting texture.

Frequently Asked Questions

Expand All:
Can I use olive oil instead of ghee?

Certainly! Olive oil is a fine substitute. Just note that the flavor profile may change slightly. Ghee brings a creamy, nutty taste that enhances the beef.

Yes, seasoning the beef overnight allows the flavors to penetrate deeper. Just make sure to refrigerate it and bring it to room temperature before cooking.

What’s the best way to serve the leftovers?

Leftover beef tenderloin slices are excellent on a fresh salad, in sandwiches, or heated with a side of mashed potatoes.

Can you cook this dish in a slow cooker?

While not traditional, it’s possible! Searing the meat beforehand remains important. Then, add it to a slow cooker with shallots and herbs on low for about 6-8 hours.

Do I need to tie the tenderloin before cooking?

While it’s not necessary, tying the tenderloin can help it cook evenly. Use kitchen twine to create a more uniform shape.
