Beef Tenderloin Roast Ingredients

For the Beef
Beef Tenderloin (4 pounds) – The star of the dish, ensuring a tender and flavorful roast. Trim evenly to cook uniformly.
Salted Butter (1 stick) – Adds richness to both the meat and the creamy sauce. Unsalted butter can be substituted but adjust salt accordingly.
Dijon Mustard (2 tablespoons) – Adds tang and depth to the butter sauce. Can be swapped with yellow mustard for a milder flavor.
Worcestershire Sauce (2 tablespoons) – Enhances umami flavor; soy sauce can be used in a pinch.
Fresh Thyme (1 tablespoon, chopped) – Adds aroma and freshness; dried thyme is a convenient alternative.
Garlic (4 cloves, chopped) – Provides fragrant flavor; garlic powder serves as a last resort if you’re out of fresh garlic.

For the Sauce
Cremini Mushrooms (2 cups, sliced) – Essential for the Marsala sauce, providing earthiness; button mushrooms work well as a substitute.
Marsala Wine (1 cup) – Adds sweetness and depth to the sauce; sherry or a splash of red wine can replace it if needed.
Heavy Cream (2 cups) – Offers creaminess to the Marsala sauce; half-and-half can lighten the richness.

For the Smashed Potatoes
Baby Potatoes – Serve as a delicious base that provides a crispy texture when smashed; Yukon Gold or red potatoes can be substituted if necessary.
Grated Parmesan (½ cup) – Elevates the flavor of the potatoes with a salty, nutty note; you can also use Pecorino Romano or nutritional yeast as alternatives.

Step‑by‑Step Instructions for Beef Tenderloin Roast with Smashed Potatoes

Step 1: Prep Meat
Remove the beef tenderloin from the refrigerator and let it sit at room temperature for at least 1 hour to ensure even cooking. While your meat rests, preheat your oven to 475°F (245°C) to get it nice and hot for the roast. This step helps the beef sear beautifully, creating a flavorful crust.

Step 2: Roast Potatoes
Halve the baby potatoes and arrange them in a large roasting pan around the beef once it’s ready. Drizzle a little olive oil over the potatoes and season with salt. As the beef tenderloin roasts, the potatoes will soak up the savory juices, enhancing their flavor. It’s the perfect foundation for your final dish.

Step 3: Butter Sauce
Melt the salted butter in a small saucepan, then mix in the Dijon mustard, Worcestershire sauce, chopped thyme, and garlic. Stir until combined, creating a rich, flavorful sauce. Pour this mixture evenly over the beef tenderloin, ensuring it is well-coated. Don’t shy away from adding a dash of salt and pepper to enhance the flavors even more.

Step 4: Cooking Beef
Place the roast in the preheated oven and cook until the internal temperature reaches 115°F (46°C) for medium-rare, which typically takes about 25 to 40 minutes. Use a reliable meat thermometer for accuracy. Keep an eye on the beef, as you want it to be beautifully browned on the outside while remaining juicy within.

Step 5: Prepare Sauce
In a skillet, sauté the sliced cremini mushrooms in a bit of butter until they are golden brown and fragrant, about 5 to 7 minutes. Add in some chopped garlic and thyme, cooking for another minute. Pour in the Marsala wine, letting it reduce for about 3–4 minutes until slightly thickened, then stir in the heavy cream and let it simmer until creamy and thickened.

Step 6: Let Rest
Once your beef tenderloin reaches the desired temperature, remove it from the oven and allow it to rest for at least 10 minutes. This resting period is crucial as it lets the juices redistribute throughout the meat, ensuring each bite is tender and succulent.

Step 7: Finish Potatoes
While the beef rests, smash the roasted baby potatoes with a fork or potato masher, taking care to keep them somewhat chunky for texture. Sprinkle the smashed potatoes with grated Parmesan, then return them to the oven for about 10 minutes until they become crispy and golden.

Step 8: Serve
Slice the beef tenderloin into thick pieces and plate it with a generous dollop of the creamy mushroom Marsala sauce. Accompany the dish with the crispy smashed potatoes for a comforting, elegant dining experience that’s perfect for your holiday meal.

How to Store and Freeze Beef Tenderloin Roast with Smashed Potatoes

Fridge: Store leftovers in an airtight container for up to 3 days. Ensure the roast and smashed potatoes are cooled before sealing to maintain freshness.

Freezer: For longer storage, freeze beef tenderloin slices and smashed potatoes separately in airtight containers or freezer bags for up to 3 months.

Reheating: Thaw leftovers in the refrigerator overnight, then reheat gently in the oven at 350°F (175°C) until warmed through. This helps preserve the texture of both the beef and potatoes.

Portion Planning: If you anticipate leftovers, consider cooking just a portion of the beef tenderloin roast to minimize excess.

Make Ahead Options

These Beef Tenderloin Roast with Smashed Potatoes are perfect for meal prep enthusiasts seeking an elegant dish without the last-minute stress! You can season and refrigerate the beef tenderloin with the butter sauce for up to 24 hours in advance, allowing the flavors to meld beautifully. The smashed potatoes can also be prepared by cooking and smashing them a day ahead, then simply refrigerate (covered) until needed. When you’re ready to serve, roast the seasoned beef and potatoes directly from the fridge, adding an extra few minutes to the roasting time if they are cold. This way, you’ll enjoy a stunning, worry-free meal with just the right amount of comfort and sophistication!

Tips for the Best Beef Tenderloin Roast

Resting is Key: Allow the beef tenderloin to rest for at least 10 minutes post-roasting to ensure juices lock in, resulting in tender slices.

Temperature Check: Use a meat thermometer to avoid overcooking—medium-rare should be around 120°F. This ensures juicy, flavorful beef tenderloin roast.

Searing for Flavor: Consider searing the beef on all sides in a hot skillet before roasting to develop a rich, caramelized crust that enhances flavor.

Potato Prep: Choose evenly sized baby potatoes for consistent cooking and crispiness. Parboil them for a few minutes before smashing for enhanced texture.

Sauce Simmer: Let the Marsala sauce simmer adequately to allow flavors to meld, creating a rich, creamy finish that complements the dish beautifully.

By following these expert tips, you can create a delicious and memorable Beef Tenderloin Roast with Smashed Potatoes that will impress your guests!

Beef Tenderloin Roast with Smashed Potatoes Recipe FAQs

How do I select the perfect beef tenderloin?
Absolutely! Look for a beef tenderloin that has a bright, rich red color with a good amount of marbling. The marbling indicates fat content, which means more flavor and tenderness. Avoid any with dark spots or an off smell, as these are signs of spoilage.

What’s the best way to store leftovers?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Make sure the beef and smashed potatoes are completely cooled before sealing. This will help maintain their freshness and flavor.

Can I freeze the beef tenderloin roast?
Definitely! For longer storage, you can freeze the beef tenderloin slices and smashed potatoes separately in airtight containers or heavy-duty freezer bags for up to 3 months. Make sure to label them with the date. When you’re ready to enjoy them, thaw in the refrigerator overnight, then gently reheat in the oven at 350°F (175°C) until warmed through to keep that delicious texture.

What if my beef tenderloin roast is overcooked?
If your roast is slightly overcooked, don’t panic! This can happen to the best of us. To add moisture back, slice the beef thinly and serve it with the creamy mushroom Marsala sauce poured generously on top. The sauce will help enhance the flavor and moisture, making the dish more enjoyable.

Are there any dietary considerations I should think about?
Absolutely! If you’re cooking for someone with allergies, be mindful of the ingredients. The beef tenderloin and potatoes are generally safe for most diets, but mushrooms and dairy (in the heavy cream) can cause issues for some. For a dairy-free version, you can substitute the heavy cream with a plant-based option or use a non-dairy milk combined with a thickening agent like cornstarch.

What can I substitute for Marsala wine in the sauce?
If you don’t have Marsala wine, you can use a dry sherry or a splash of red wine as alternatives. If you want to avoid alcohol altogether, consider using a mixture of grape juice with a touch of vinegar for a similar sweetness and acidity, allowing you to still enjoy a flavorful sauce.

Each of these FAQs will help you make the most out of your Beef Tenderloin Roast with Smashed Potatoes recipe and keep your cooking stress-free and enjoyable!
