Medallions of Beef with Caramelized Red Wine Onions
Directions
-
Preheat oven to 350°F (180°C). In a large heavy skillet over medium-low heat, melt butter. Add onions and cook until caramelized, 15 to 20 min, stirring often.
-
Season beef medallions with pepper and 1 tsp (5 mL) salt. Heat oil in a large ovenproof skillet over high heat. When hot, sear steaks 1 min. per side (in batches if necessary to avoid overcrowding). If skillet is large enough, place in oven and cook steaks to desired degree of doneness, 7 to 10 min. for medium. (Or place steaks on a baking sheet and place in the oven to finish cooking).
-
Remove beef medallions, set aside to rest. Add red wine, beef broth, cream and peppercorns to skillet, stirring to deglaze pan. Simmer to reduce liquid to half, about 5 to 7 min. Add caramelized onions, remaining salt and thyme and stir to combine. Serve sauce over beef medallions.
