- Total time 1 hour
Gratin: In large nonstick skillet, cook bacon over medium-high heat, turning once, until crisp, about 4 minutes. Remove to paper towel–lined plate to drain. Chop bacon into 1/2-inch (1 cm) pieces. Set aside.
Reserving 2 tsp of the fat, drain pan; wipe clean. Return reserved fat to pan. Add oil; heat over medium-high heat. Cook fennel and carrots, stirring and adding water, 1 tbsp at a time, if fennel begins to stick to pan, just until fennel is softened, about 7 minutes. Remove to plate.
In same pan, bring potatoes, broth, cream, milk, thyme, garlic, salt and pepper to boil over medium-high heat. Reduce heat to medium; simmer until potatoes are almost tender, about 10 minutes.
Whisk flour with 1/4 cup water. Move potatoes to 1 side of pan; whisk flour mixture into opposite side until smooth. Add bacon and fennel mixture; cook, stirring, until potatoes are fork-tender, about 2 minutes. Discard thyme.
Spoon half of the potato mixture into greased 13- x 9-inch (3 L) baking dish; sprinkle with Gruyère. Scrape remaining potato mixture over top. (Make-ahead: Let cool completely; cover with foil. Refrigerate for up to 24 hours. Reheat, covered, on bottom rack of 425°F/220°C oven for 45 minutes before continuing with recipe.)
Topping: Stir together bread crumbs, Gruyère and butter. Sprinkle over potato mixture.
Bake on bottom rack of 425°F (220°C) oven until top is golden, about 15 minutes. Let stand for 10 minutes before serving.
