We really enjoyed this. I used a 3 lb sirloin tip roast because I didn't want to have to go buy a tenderloin. I marinated it for about an hour and it worked out great. Very tender. My kids don't care for blue cheese so I served their pieces without any sauce..even without the sauce the meat had a very nice flavor from the marinade so it's a recipe that you can easily serve with the sauce "on the side." Everyone cleaned their plates! Served with baked potatoes (my husband liked the sauce added on his potato, too) corn and warm buttered bread. A keeper.

Excellent recipe. Note, it's cheaper to buy tenderloin as a whole, rather than filets anyway. Also, make sure you buy quality blue cheese as it does make the sauce. I followed the recipe and it was fabulous. I did change the cooking method slightly. I put the tenderloin in the pre-heated oven at 450 degrees for 15 minutes. I then had my hubby grill to an internal temperature of 120 degrees. Wonderful! Will definitely make again.

I went with goat cheese and sun dried tomatoes crumbled over the finished tenderloin instead of blue cheese. I also reduced down (after it was brought to a rolling boil) the remaining marinade and spooned it over the beef. It was very well liked by everyone in my family. The marinade itself is very good and am thinking I'll try it for chicken some time. Thanks for the recipe!

WONDERFUL!!!

I used the marinade and bleu cheese topping on tenderloin steaks-they came out wonderful!

I did not marinate the meat, but the cooking method is the best way to cook a whole tenderloin that I have tried. Superb!

Soooo good!! Everyone loved it. It was so tender. I followed this recipe almost exactly & it was great. I did add a little more mayo. & sour cream to the topping mixture.

This was wonderful!!! I cooked it for our Valentines dinner and everyone swooned! My 2 year old who is not much of a beef eater ate more than her big brothers. I did have to cook it a bit longer since we don't care for rare meat but even with a longer roasting time it was tender and delicious. The sauce is all too fabulous, I had to restrain myself from eating it with a spoon!

Didn't use the marinade recipe because I ran out of time. Just let the tenderloin come to room temp, sprinkled generously with Canadian Steak Seasoning and pan roasted until med-rare. Made this sauce with reduced fat mayo and lite sour cream and used about 2 tsp of worcestershire. Sliced the tenderloin very thin, placed on thin slices of baquette and topped with this sauce. Can't wait to make this again!!! Absolutely wonderful!!!

Fantastic! Fantastic! Fantastic!

Melt in your mouth delicious. We used a 6 lb. tenderloin and didn't have to double the blue cheese mixture but we doubled the marinade. Marinated it for 8 hours or so. I was definitely a keeper but it's really expensive! Thanks!!!

This deserves 10 Stars!. Made this for Christmas. Used a 7lb tenderloin. Made just as directed and wouldn't change a thing. My mother in law went on and on how good it was. It was so easy too and the blue cheese sauce really topped it off just right. A DEFINATE KEEPER. Can't wait to make again.

I can't wait to make this again!

Wonderful restaurant-like recipe! I didn't have beef tenderloin and replaced it with an inch thick, well-done beef sirloin. Blue cheese on top of beef makes a great, tasty combination! I added extra blue cheese for good measure; 1 ounce of blue cheese wasn't good enough for me! :-) A side dish of sour cream and chive potatoes along with a good bottle of red wine add great flavor and ambiance to this great recipe.

My husband loves meat of all types, but I'm not a huge fan. Usually. This was probably the best beef dish I've ever had. I even had seconds.

WE tried this about a week ago and used Oregon state blue cheese and a fine Oregon Sirah. Wonderful! We substituted Elk back strap, which is much better for you and can cut down the expense considerably. It will lower your cholesterol, specifiacally the "BAD" stuff(LDL). For those that don't hunt, this recipe is an arterial clogger. I am a physician and watch that at least 80% of the red meat we ingest is game.

This was delicious! The meat was flavorful and juicy. The sauce was perfect. Smooth, creamy and not too strong. My guests loved it and several asked for the recipe.
