For the Marsala Mushroom Sauce

How to Make Beef Tenderloin Roast with Smashed Potatoes
Prepare the Beef: Start by generously coating your beef tenderloin with garlic herb butter. Sear it in a hot, oven-safe skillet over medium-high heat until it s beautifully browned approximately 3-4 minutes on each side.
Roast: After searing, carefully transfer the skillet to a preheated oven at 400 °F. Roast the tenderloin until it reaches your desired doneness, about 20-25 minutes for medium-rare. Let it rest for at least 10 minutes before slicing to keep the juices intact.
Prepare Smashed Potatoes: While the beef is roasting, boil Yukon gold potatoes in salted water until fork-tender, around 15-20 minutes. Drain well, then gently smash each potato with a fork and drizzle with olive oil, garlic powder, salt, and grated Parmesan cheese.
Roast Potatoes: Place the smashed potatoes on a baking sheet and roast in the same oven for 25-30 minutes or until they are golden brown and crispy on the outside.
Make Marsala Sauce: In a saucepan, saut diced mushrooms and onions over medium heat until softened, about 5 minutes. Add Marsala wine, beef stock, and heavy cream; simmer for about 10-15 minutes until thickened. Stir in fresh thyme just before removing from heat.
Serve: Slice the rested beef and plate it alongside the crispy smashed potatoes. Drizzle the savory Marsala mushroom sauce generously over the beef for a luxurious finish.
Optional: Garnish with additional fresh thyme for a touch of color and flavor.

Make Ahead Options
These Beef Tenderloin Roast with Smashed Potatoes are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the garlic herb butter and coat the beef tenderloin up to 24 hours in advance; simply keep it wrapped in the refrigerator to maintain its freshness. The smashed potatoes can also be boiled and smashed a day ahead; simply refrigerate them after seasoning. When ready to serve, reheat the potatoes in the oven while you roast the beef (which takes about 25 minutes), and finish the Marsala sauce as directed. This way, you can create a luxurious meal with minimal effort, impressing your guests just as much as if you had prepared everything from scratch on the day!
Expert Tips for Beef Tenderloin Roast
Room Temperature Beef: Allow the beef tenderloin to reach room temperature before cooking. This ensures more even cooking and prevents a cold center.
Use a Meat Thermometer: Avoid overcooking by using a meat thermometer to check for doneness; medium-rare is around 135 °F.
Resting Time is Key: After roasting, let the tenderloin rest for at least 10 minutes. This helps retain its juices for a more flavorful Beef Tenderloin Roast.
Crispier Potatoes: For extra crispy smashed potatoes, make sure they have enough space on the baking sheet and consider broiling them briefly at the end.
Flavor Boost: Experiment with fresh herbs in your garlic herb butter to elevate the flavor of the tenderloin. Use thyme or rosemary for a delightful twist.
