Perfect Roast Beef with Gravy

This dish is such a treat!  Super easy and super delicious!  The veggies are also very flavorful and they melt in your mouth.  I served ours with my simple mashies.  Enjoy!

Ingredients:
-1 (about 3 lbs) beef roast, trimmed of excess fat
-salt and pepper
-4 Tbs extra virgin olive oil, divided
-8 oz mushrooms, thickly sliced
-1 large onion, thickly sliced
-1 cup red grape juice
-1 cup beef stock
-2 Tbs flour
Directions:
Preheat oven to 375 F.
Season the roast with salt and pepper.  In an oven proof large skillet, heat 2 Tbs of the oil.  Add the meat and sear on all sides.
While that is going, add the mushrooms and onions to a bowl.  Stir in the other 2 Tbs of oil and season with salt and pepper.  Mix well.  Add mixture to the skillet, all around the roast.
Place skillet in preheated oven and cook for 40 minutes.  Remove roast from pan and let rest.  Place mushrooms and onions on a different plate.
Return the skillet to the stove, on medium heat.  Add grape juice and stock, scraping the browned bits on the bottom of the pan, to get all the yummy stuff.  Whisk in the flour and cook until the gravy is thickened and smooth.
Slice the beef into thin slices and top with veggies.  Pour gravy on top of mashies.  Enjoy!
