- Olive oil
- 1 1/4 pounds plum tomatoes, halved lengthwise
- 2 large red bell peppers, halved lengthwise, seeded
- 5 tablespoons butter
- 4 large shallots, minced
- 1 14 1/2-ounce can low-salt chicken broth
- 1/2 cup dry white wine
- 3/4 cup chopped fresh basil
- 1/2 teaspoon dried crushed red pepper
- 8 8-ounce filet mignon steaks (each about 1 inch thick)
- 1/4 cup water
- Preheat broiler. Brush large baking sheet with oil. Place tomatoes and bell peppers, cut side down, on prepared sheet. Broil until tomatoes and peppers begin to char and blister, about 5 minutes. Cool. Peel skins from 1 pepper half, then cut into thin strips; set aside. Chop tomatoes and remaining peppers (do not peel).
- Melt 1 tablespoon butter in large nonstick skillet over medium heat. Add shallots and sauté until tender, about 4 minutes. Add broth and wine; bring to boil. Add chopped tomatoes, chopped bell peppers, 1/2 cup basil, and crushed red pepper. Boil mixture gently until reduced to 2 cups, stirring occasionally, about 15 minutes. Cool slightly. Puree mixture in blender until smooth. Pour into strainer set over bowl, pressing on solids to extract as much liquid as possible; set aside. (Sauce can be made 1 day ahead. Cover and chill.)
- Heat heavy large skillet (preferably cast iron) over high heat. Sprinkle steaks with salt and pepper. Working in batches, add steaks to hot dry skillet and cook about 4 minutes per side for medium-rare. Transfer to platter; cover to keep warm. Add 1/4 cup water to skillet; stir to scrape up browned bits. Add sauce to skillet; reduce heat and simmer until heated through, about 4 minutes. Remove from heat. Whisk in remaining 4 tablespoons butter, then remaining 1/4 cup basil. Season sauce with salt and pepper.
- Place 1 steak on each of 8 plates. Drizzle sauce over. Garnish steaks with reserved pepper strips and serve.
