French Beef Au Gratin - cooking recipe

Ingredients

1/2 cup butter or 1/2 cup margarine
4 cups thinly sliced vidalia onions or 4 cups any sweet onions
1 lb beef tenderloin (I buy the pre-cut beef stew tips) or 1 lb sirloin, cut into 1/2 \" cubes (I buy the pre-cut beef stew tips)
3 tablespoons flour
1 tablespoon dark brown sugar, packed
1 teaspoon cumin
1 teaspoon salt
1/2 teaspoon pepper
1 quart beef broth
2 cups cooked fettuccine pasta
1 cup shredded mozzarella cheese
1/2 cup parmesan cheese, grated

Preparation

In large, heavy bottomed pan, over medium heat, melt butter.
Add onions; saute, stirring often, until caramelized, but not burned, 15 to 20 minutes.
With slotted spoon, remove onions to medium bowl.
Add beef to pan; brown well on all sides.
Return onions and any juices to pan.
In small bowl, mix flour, sugar, cumin, salt and pepper and add to pan; stir 1 minute until bubbly. Gradually add broth, stirring to scrape drippings from pan; simmer 10 minutes.
Cook pasta according to package directions.
Heat broiler; place 1/2 cup fettucine in each of 4 ovenproof bowls; divide beef mixture over pasta.
In medium bowl, stir cheeses together; sprinkle evenly over beef.
Broil until cheese is melted and lightly browned, about 5 minutes. Makes 4 servings.
