Place onion on the bottom of a roasting pan.
Top with meat (rinse off with water first)
Preheat the oven to 375
Combine garlic, oil, and all spices in a bowl and cover the meat.
Let it sit for an hour or two to absorb the flavors.
Combine the wine, water, and ketchup and pour over the meat.
Insert an oven thermometer into the thickest part of the meat.
Place in the oven uncovered for 45 minutes
Cover the meat and let it cook until the thermometer shows 135 degrees.
The meat will be rare at that time BUT… the meat continues to cook after you take it out of the oven.
Let me meat cool for 30-45 before slicing thin.
Cover with juices and warm it up in the oven if you like well done.
