Time 40m

Yield 36 crostinis, 8-10 serving(s)

Number Of Ingredients 16

1 1/2 lbs roast beef, peppered (right from your grocers deli - 1/4-inch thick slices)
1/4 cup marsala wine
3/4 cup beef broth
3 cups onions, cut in quarters and thin sliced (2 large)
1 teaspoon butter
1 teaspoon olive oil
1/2 teaspoon sugar
1/2 teaspoon salt
1 head garlic, peeled
1 cup olive oil
2/3 cup sour cream
2 1/2 tablespoons prepared horseradish (more or less according to taste)
1/2 teaspoon white wine vinegar
salt
pepper
1 tablespoon fresh chives, fine chopped

Steps:

  • Lets start with all the components and make them one at a time.
  • Horseradish Cream -- Just mix the sour cream, prepared horseradish (not creamy), vinegar, and season with a little salt and pepper to taste. Refrigerate until ready to use. The chives should be added right before serving.
  • Onions -- To a medium to large sauce pan, add the butter and olive oil and bring to medium heat. Add the onions and slowly begin to caramelize them - don't rush this. It will take a good thirty minutes, but it isn't hard. After 5 minutes add a pinch of salt and sugar and continue to stir now and then. After 15 minutes the moisture (water) from the onions will start to evaporate and the onions begin to caramelize. Once they get golden brown, remove, let cool and refrigerate until you are ready to use them. They can be reheated in the microwave in just a minute when you are ready to make the crostini.
  • Garlic Oil -- In a small sauce pan on medium heat, add the oil and garlic. Cook for just a minute on medium and then reduce to medium low and simmer for about 20 minutes until the garlic is golden brown. Remove the garlic and you have wonderful garlic oil. You can always buy a bottle which is expensive, and not nearly as good.
  • Beef -- Add the beef broth and marsala to a small bowl to a small pan and heat until warm. Add in the beef slices and cook just a minute or two until the beef is warm. You don't want to over cook it, it doesn't take long.
  • Crostini -- Slice and grill or broil just until golden brown on each side. Remove and brush each slice with some of the garlic oil.
  • Onions -- As the bread is toasting and the beef warming up - heat up your onions for just 1 minute in the microwave, they are all done you just want them warm.
  • Horseradish Cream -- Don't forget to stir in the chives right before you are ready to serve.
  • Toppings -- Top each garlic crostini with some of the warmed caramelized onions, then a slice or two of beef, then a little of the horseradish cream.
  • ENJOY!

FIG, CARAMELIZED ONION & GORGONZOLA CROSTINI



Fig, Caramelized Onion & Gorgonzola Crostini image

A friend gave me this recipe about 10 years ago. I tweaked it a little. It's always a hit when I make it for special occasions and parties. I always double and sometimes triple the recipe depending on how many guests. Also, I make the fig jam ahead of time and sometimes caramelize the onions the day before. That's a real time...
