Toss the Brussels sprouts and 1 tablespoon of the olive oil in a large bowl. Place on a large rimmed baking sheet. Sprinkle with the salt and pepper. Bake for 20 minutes or until crisp-tender and lightly browned. Remove from the oven and reduce oven temperature to 400 degrees.
Meanwhile, coat a 6 to 8 cup baking dish with nonstick cooking spray and toss the breadcrumbs in a small bowl with the remaining 1/2 tablespoon olive oil.
Arrange half of the roasted sprouts in the baking dish and top with half each of the cottage cheese, cream and bacon.
Top with the remaining sprouts, cottage cheese, cream and bacon. Sprinkle with the Gruyère cheese and breadcrumbs.
Bake at 400 degrees for 10 to 15 minutes or until the cheese is melted and the mixture is hot and golden brown. Let stand for 5 minutes before serving.
