Preheat your oven to 425°F.
Peel the outer layers of the garlic bulb, leaving the cloves intact.
In a 13x9 baking dish, combine cherry tomatoes, shallot, oregano, thyme, basil, and crushed red pepper. Place the garlic bulb in the center.
Drizzle with olive oil, and season with salt and pepper.
Bake for 40-45 minutes until tomatoes burst, and garlic is tender.
Meanwhile, cook the pasta until al-dente according to the package instructions. Save 1 cup of pasta water.
Allow the tomato mixture to cool slightly, then transfer it to a blender with the heavy cream. Blend until smooth.
Transfer the sauce to a pot with the cooked pasta, Parmesan cheese, and pasta water if needed. Stir well to combine.
Serve warm and enjoy!
