Food Network and Williams-Sonoma both provide good recipes for bacon-wrapped filet mignon. While the Food Network recipe uses butter and olive oil, the Williams-Sonoma recipe requires truffle oil.
The Food Network recipe includes kosher salt and freshly ground black pepper, an 8- to 10-ounce beef filet steak approximately 2 inches thick, a piece of thinly sliced bacon, 1 tablespoon of butter and 1 tablespoon of olive oil. Preheat an oven to 450 degrees Fahrenheit.
Add salt and pepper to both sides of the steak. Wrap the steak with the bacon, and use a toothpick to keep the bacon intact around the steak. Heat an ovenproof skillet over medium-high heat. Melt the butter and olive oil on the skillet. Add the steak to the skillet and sear it on both sides until for one minute on each side.
Remove the steak from the skillet and place it in the oven to finish cooking. Cook it for about seven to 10 minutes. Remove it from the oven and allow it to rest for five minutes before serving.
The Williams-Sonoma recipe requires the same basic preparation, but the recipe uses truffle oil. It also suggests trimming the fat from the filet mignon before wrapping it with the bacon. The recipe yields four servings, rather than one serving. The cooking time varies based on how individuals like their steaks prepared.
