Ingredients
Getting your hands on the right ingredients for this garlic-studded beef tenderloin is honestly half the battle won. You’re not dealing with some exotic shopping list that sends you hunting through specialty stores—most of these items are probably sitting in your kitchen right now, just waiting to become part of something magnificent.
For the Beef Tenderloin:
- 1 (3-4 lb) beef tenderloin
- 2 garlic cloves, thinly slivered
- 1-2 tablespoons olive oil
- 1 tablespoon fresh coarse ground black pepper
- 1 tablespoon chopped fresh thyme (or 1 teaspoon dried thyme)
- Coarse salt, to taste
For the Mustard Horseradish Cream Sauce:
- 1/3 cup Dijon mustard
- 1/3 cup sour cream
- 1/4 cup prepared mayonnaise
- 1/4 cup well-drained prepared white horseradish
Now, let’s talk about the star of the show—that beef tenderloin. Don’t skimp here, because you’re basically building your entire meal around this gorgeous piece of meat. Look for one that’s nicely trimmed with minimal silver skin, and if your butcher offers to clean it up for you, take them up on that offer.
Fresh thyme makes a noticeable difference over dried, but we’re not going to judge if you reach for the dried stuff on a busy Tuesday. As for the horseradish in your sauce, make sure you drain it well unless you want your cream sauce looking more like soup.
How to Make this Garlic-Studded Beef Tenderloin with Horseradish Cream
Making this garlic-studded beef tenderloin is surprisingly straightforward once you get your hands dirty—literally. Start by preheating your oven to 425°F, because nobody wants to stand around holding a beautiful piece of meat while waiting for the oven to catch up.
Now comes the fun part: take that sharp knife and cut small slits all over your 3-4 pound beef tenderloin, then stuff those 2 thinly slivered garlic cloves right into the slits like you’re giving your beef a little garlic massage. Don’t be shy about it—you want that garlic flavor distributed throughout, not just sitting politely on the surface.
Brush the whole thing with 1-2 tablespoons of olive oil, then get those hands working again as you rub 1 tablespoon of fresh coarse ground black pepper and 1 tablespoon of fresh thyme all over the meat. Finish with a generous sprinkle of coarse salt, because we’re not playing around here.
Place your seasoned masterpiece on a rack in a shallow roasting pan and slide it into that hot 425°F oven for exactly 15 minutes—this initial blast of heat is going to give you that gorgeous crust. For perfectly even cooking and easy cleanup, consider using a premium seafood cookware set that doubles as exceptional roasting equipment for all your proteins.
After those 15 minutes are up, drop the temperature to 350°F and roast for another 20 minutes if you want medium-rare, or 25 minutes total if medium is more your speed. Here’s where patience becomes your best friend: let that tenderloin rest for a full 15 minutes before you even think about slicing into it, unless you want all those beautiful juices running across your cutting board instead of staying put in the meat where they belong.
While your beef is taking its well-deserved break, whisk together your sauce by combining 1/3 cup Dijon mustard, 1/3 cup sour cream, 1/4 cup mayonnaise, and 1/4 cup of that well-drained white horseradish. This tangy, creamy situation is going to be the perfect companion to your perfectly cooked beef.
Slice your tenderloin into thick 1/2-inch pieces, arrange them on your prettiest platter, and serve alongside that mustard horseradish cream sauce that’s practically begging to be dolloped on every single bite.
Substitutions and Variations
Since this recipe is already pretty flexible, you’ve got plenty of room to play around with ingredients based on what’s hiding in your pantry or your personal taste preferences.
Don’t have fresh thyme? Rosemary works beautifully, though I’d use it sparingly since it’s more potent. You can swap the Dijon for whole grain mustard if you like texture in your sauce.
No sour cream? Greek yogurt makes an excellent substitute and adds extra tang.
For the garlic-phobes in your life, you can reduce the cloves or skip them entirely. The beef will still taste incredible with just the herb and pepper coating.
Additional Things to Serve With Garlic-Studded Beef Tenderloin with Horseradish Cream
This gorgeous beef tenderloin practically begs for sides that’ll complement its rich, garlicky flavors without competing for the spotlight.
I love pairing it with roasted asparagus or Brussels sprouts—those earthy vegetables play beautifully against the beef’s intensity.
Creamy mashed potatoes or buttery fingerlings work magic too, soaking up every drop of those savory juices.
Want something lighter? A simple arugula salad with lemon vinaigrette cuts through the richness perfectly.
Roasted carrots add sweetness, while sautéed mushrooms double down on that umami goodness.
Whatever you choose, keep it elegant but unfussy—this tenderloin’s already doing the heavy lifting.
Final Thoughts
Honestly, I can’t think of many dishes that deliver this kind of wow factor with so little fuss. This tenderloin practically cooks itself while you focus on other things, like setting the table or opening wine.
The garlic infuses every bite with subtle warmth, and that horseradish cream? Pure magic alongside the perfectly seasoned beef.
Sure, it’s not exactly budget-friendly, but some occasions call for splurging. When you want to impress without stress, this recipe delivers.
Simple techniques, restaurant-quality results. What more could you ask for in a special dinner centerpiece?
