16 ounces pasta of your choice like strozzapreti, rigatoni, penne, rotini, or fusilli
2 tablespoons neutral oil
2 red bell peppers trimmed, seeded, and quartered
1 yellow onion peeled and diced
1 pound Brussels sprouts halved
4 tablespoons butter
1 teaspoon dry thyme
½ teaspoon crushed red pepper plus more if desired
⅓ cup all-purpose flour
1½ cups homemade chicken stock from above or use store-bought stock
1 cup heavy cream
1 cup freshly grated Parmesan cheese
Salt and pepper to taste
Freshly minced parsley optional, for garnish

Cover split chicken breasts with water and season liberally with salt. Add the quartered onion and halved head of garlic. Bring to a boil and then reduce heat and simmer for 30–40 minutes until the chicken is cooked through. Skim off the foam that floats to the top as the chicken cooks.
Use tongs to transfer the chicken to a plate and let it cool. Bring the stock back to a boil and boil for 15 minutes until significantly reduced. Strain through a sieve into a large bowl and set aside. You will need 1½ cups stock for the recipe, and any extra stock can be saved for another use.
Once the chicken is cool enough to handle, shred it with your fingers, two forks, or dice it up. Discard the skin and bones.
Wipe out the pot used for the stock and fill it back up with salted water and return it to the stovetop. You'll use it for the pasta later on.

While the stock cooks, prepare the red bell peppers. Arrange the prepared peppers on a baking sheet and drizzle with 1 tablespoon oil. Place under a broiler and cook for 7–8 minutes until blackened all over. Keep an eye on them, so they don't burn to a crisp!
Immediately transfer the peppers to a Tupperware dish with a lid or a gallon freezer bag. The trapped steam will help the skins come off easily. Peel the peppers and roughly chop and set aside.
Turn the broiler off and turn the oven's heat to 400ºF.

Bring the pot of salted water to a boil. Cook the pasta until 2 minutes under al dente. Drain and set aside.

In a wide, oven-proof pot, heat 1 tablespoon oil over medium-high heat. Cook the onion until softened–about 7–10 minutes–and then turn the heat to high. Add the Brussels sprouts and cook for 6 minutes until well-charred. Add the chopped red peppers and cook for 2 minutes more. Season with salt and pepper. Transfer the vegetables to a bowl.

Melt the butter in the pot over medium heat. Once bubbly, add dry thyme and crushed red pepper and cook for 1 minute. Add flour to the butter and cook for 2–3 minutes until lightly golden. Slowly whisk in the reserved chicken stock. Bring to a low boil and then reduce heat and continue whisking until completely smooth.
Stir in the heavy cream and whisk until smooth. Taste and season with salt, pepper, and more crushed red pepper if you like. Turn off the heat.

To the sauce, add the cooked chicken, cooked pasta, and the reserved vegetables and toss to coat and evenly distribute the ingredients. Sprinkle the parmesan cheese on top and transfer to the oven for 10–15 minutes or until the Brussels sprouts are fork-tender and the cheese is melted. If you like, broil for 2–3 minutes to char the top of the pasta.
