Preheat the oven to 350°F (180°C). While it heats, slice the baguette and cut the cherry tomatoes in half. Arrange both on a baking sheet. Drizzle the bread with olive oil, sprinkle with salt and rosemary. Drizzle the tomatoes with olive oil, salt, and oregano. Once the oven is hot, bake in the center for 10 minutes.

Meanwhile, score the Camembert into 8 sections, being careful not to cut through the edges. Slice the garlic cloves and tuck the slices into the cuts in the cheese. Drizzle with olive oil, and sprinkle with black pepper and rosemary. After the first 10 minutes, flip the bread slices and add the cheese to the baking sheet. Return everything to the oven for another 3–4 minutes.
