"This was a fantastic base recipe, but I did change one major thing - I only used 1 large onion instead of 3. We like cooked onions in our dishes, but not THAT MUCH. I can't imagine 3 whole onions. Otherwise, it was fantastic.

"I made this exactly as the recipe called for and they were phenomenal! I couldn't believe how easy it was to make, I had always expected this dish to be time consuming and tedious.
The only drawback to my dish was the tenderloins were so thick that they were almost completely rare after the 20 min baking time. I stuck them back into the oven for an additional 5 minutes for medium rare and then another few minutes for my daughter's serving, which she likes more medium well.
Its a costly dish to make, so I will save this recipe for special occasions. :)

"I made this for the first time this week and the family raved about it! I couldn't find truffle butter at any of my local groceries so I made my own (1 stick of unsalted sweet cream butter + 1/2 teaspoon white truffle oil) for the recipe. Will definitely be making this again!
