Pro Tips for Tender Roasted Beef with Caramelized Onions and Horseradish

To make the most of this delicious roasted beef tenderloin recipe, take the time to caramelize the onions slowly over medium-low heat. This patient process will develop deep flavors and a luxurious sweetness that elevates the dish. Stir frequently and let them cook for about 45 minutes until they turn a deep golden color.

When preparing the horseradish sauce, ensure to mix the mayonnaise, sour cream, prepared horseradish, lemon zest, and juice thoroughly. This creamy and tangy sauce perfectly complements the rich flavor of the beef and the sweetness of the caramelized onions. Make the sauce ahead of time to allow the flavors to meld together for the best results.

For a perfect roast, remember to let the beef tenderloin rest after cooking. This step allows the juices to redistribute within the meat, ensuring each slice is juicy and flavorful. Garnish with fresh thyme leaves for a burst of aroma and color, enhancing the overall appeal and taste of this impressive dish.

How to Make Tender Roasted Beef with Caramelized Onions and Horseradish

Step 1: Caramelize the Onions

In a large pot over medium-high heat, heat olive oil and butter. Add sliced onions, season with kosher salt and black pepper, and cook for 10 minutes, stirring often. Reduce heat to medium-low, add thyme, rosemary, and bay leaf. Cook for about 45 minutes until caramelized. Stir in sherry wine, simmer for 15 minutes, remove herbs, adjust seasoning, and keep warm.

Step 2: Prepare Horseradish Sauce

Combine mayonnaise, sour cream, horseradish, lemon zest, lemon juice in a bowl. Whisk until smooth. Season with salt and pepper. Refrigerate until serving.

Step 3: Roast the Beef Tenderloin

Preheat oven to 450°F (232°C). Place beef tenderloin on a rack over a sheet pan. Pat dry and let rest at room temperature for 20 minutes. Drizzle with olive oil, season with kosher salt, granulated garlic, and black pepper. Roast for 30 minutes until internal temperature reaches 135°F (57°C) for medium-rare. Rest covered with foil for 15 minutes before serving.

Step 4: Slice and Serve

Slice beef tenderloin into 1/4-inch thick pieces and place on a platter. Top with caramelized onions, serve with horseradish sauce, and garnish with fresh thyme leaves.

Storage Tips

To store the finished dish, it is recommended to wrap leftover beef tightly in plastic wrap or foil and refrigerate it for up to three days. It is best to slice only what you plan to eat immediately to help retain its juiciness. The caramelized onions and horseradish sauce can both be stored in airtight containers in the refrigerator for a couple of days. This allows you to enjoy the dish over multiple meals without compromising its quality.

For longer storage options, while the cooked beef is not ideal for freezing due to texture changes, you can freeze the caramelized onions in a freezer bag for future use. The horseradish sauce is best made fresh but you can prepare the plain beef loin, freeze it after roasting, and then slice and reheat it gently in the oven when you’re ready to enjoy it again. By properly storing the components of the dish, you can savor the flavors of this roast beef with caramelized onions and horseradish over multiple meals, ensuring that each bite is as delicious as the first.

Ingredient Substitutions

If you are unable to find fresh herbs, you can substitute them with half the amount of dried thyme and rosemary. Just remember that dried herbs are more potent than fresh, so adjust accordingly to avoid overpowering the dish with their flavor.

If sherry wine is not available, you can use a substitute like a splash of dry white wine or apple cider vinegar to provide a similar sweet acidity to the caramelized onions. This swap will still offer the depth of flavor needed to complement the beef and onions in the dish.

For a tangier twist, Greek yogurt can be used as a substitute for sour cream in the horseradish sauce. This substitution will add a slightly tangy flavor to the sauce while maintaining its creamy texture, making it a suitable alternative for those who prefer a bit more tanginess in their sauces.

Serving Suggestions

For a creative serving suggestion, try plating the roasted beef tenderloin with caramelized onions and horseradish sauce on a bed of creamy mashed potatoes, allowing the flavors to meld together for a comforting and elegant presentation. Garnish with a sprinkle of fresh thyme leaves for a pop of color and aroma that enhances the dish’s visual appeal.

Another delightful way to serve this dish is to create a build-your-own sandwich station with sliced roasted beef, caramelized onions, and horseradish sauce alongside a selection of freshly baked poppy seed rolls, crisp lettuce leaves, and sliced tomatoes. Let your guests customize their sandwiches to their liking, adding a touch of freshness and interactivity to your gathering.
