The Perfect Filet Mignon Roast

The Perfect Filet Mignon Roast by

The Perfect Filet Mignon Roast ~ is crusty on the outside, but also moist, juicy and tender on the inside and seasoned to perfection! The meat is so unbelievably moist, it’s like butter!

We gave this roast its full flavor by adding prosciutto, onions and seasonings. But the secret to making a perfect roast is keeping water at the bottom of the pan while roasting in the oven.

We highly recommend using a roasting rack with this recipe.  This helps keep the roast super moist while cooking.  It’s also the reason why it’s so tender.

Not everyone prefers poultry, turkey or even a glazed ham for the holidays.

Our family LOVES this Filet Mignon Roast on special occasions and it’s a nice alternative.  Serve this roast as your main course with your favorite side dishes.  And, don’t forget the wine!  Definitely a red! …we prefer to pair it with a Chianti.

Enjoy this fantastic feast!

The Perfect Filet Mignon Roast

1.  Preheat oven to 350 degrees.

2.  In a large roasting pan with a roasting rack that fits most roasting pans, lay the slices of the prosciutto on the bottom of rack horizontally, overlapping slices.  Place the Filet Mignon roast on top of  prosciutto.  Season the meat with salt, pepper and garlic powder generously.

3.  Scatter sliced onions on top.

4.  Pour about 4 cups of water in the bottom of roasting pan, (under the roasting rack) just below the meat but not touching.  Drizzle olive oil over meat.

5.  Cook for 20 minutes per pound, about 2 hours.  Rotate the roast every half hour.
Remove from rack, and place onto cutting board, allow the roast to sit for 5 to 7 minutes before carving.

6.  Carve into 1-inch slices.  Remove the string, and transfer slices onto a serving platter.  Serve immediately.

Serves 6 to 8

Serve with our vegetable sides like EASY Garlic Mashed Potatoes and Sweet Baby Peas with Onions and Capers.

    This is exactly why I will never be a vegetarian. I could live without burgers and other meat products – but slice a pink steak like this and I start to drool! This is beautiful. We always do a tenderloin roast for Christmas and your recipe sounds terrific! Thanks – have a blessed Thanksgiving.

    Wow, that does look like the perfectly cooked tenderloin roast! The onions and prosciutto must be terrific flavor enhancers. A great recipe to have when it's too chilly for outdoor grilling.

    What do you do with the onions and prosciutto?

    • Reply
      January 29, 2015 at 5:19 pm

      Hi A! You don't have to do anything with the onions or prosciutto l, the tenderloin will absorb their flavors while cooking and will give flavor to the juices under the meat. Sometimes we spoon some of the crispy prosciutto along with the juices over the meat before serving.

    Hello, Sorry to sound so simple, but what do you mean exactly by rotating the roast? Thanx~

    • Reply
      December 23, 2016 at 10:23 pm

      Rotating the roast, means to turn it over to brown all sides evenly while roasting in the oven. I prefer turning it a few times on the rack, turning a 1/4 turn- (rotating the roast) every 30 minutes or so. Makes the outside crusty while it helps cook the meat evenly . I hope this helps. Thanks for asking.

    Hi there…this sounds absolutely scrummy! When you rotate, I take it the prosciutto remains on the bottom or does it stick to the roast? As well with the onions, do you simply place them back on top of the roast after the rotation? Do you think instead of prosciutto could one use pancetta instead?

      Yes Darrin, you can use pancetta with the roast and yes you can place them back on top after you rotate the roast. Hope this helps!! Enjoy!
