Italian Beef Tenderloin

This is very flavorful and almost melts in your mouth. The cut of meat is expensive, but it is worth it! I did make this in a crock pot with a regular rump roast. You still get the flavor and it does make a yummy roast. Although, I do recommend the tenderloin the most.
Ingredients:
Beef tenderloin roast (4-5 lbs.)
2 TBSP. olive oil
1 tsp. basil
1 tsp. thyme
1 tsp. pepper
1 tsp. Oregano
1 tsp. garlic powder
1 tsp. salt
1 tsp. minced garlic

Gravy:
1 small yellow onion, chopped
2 TBSP. butter
1/4 cup water
1 TBSP. corn starch
1 tsp. dijon mustard
1 tsp. tomato paste
1 can beef broth
2 cups portabella mushrooms, sliced

Directions: Take the first set of ingredients and combine all the spices in a bowl. Take the olive oil and spread over the roast. Then coat the roast with the spices. Brown until a crisp outer coating on all sides. Then place in a roasting pan on a rack and roast it at Bake 425 for 35-40 minutes, rotating occasionally. Then remove from the oven, cover with tinfoil and let sit for 20 minutes before slicing.

Gravy: Saute the onion and mushrooms in the 2 TBSP. butter, mix the corn starch in the 1/4 cup cold water and add to the onion/mushroom mixture. Add the can of beef broth and the tomato paste and mustard. Bring to a boil and then simmer until thickened. Serve over the roast.
