Preheat oven to 300 degrees F.
Pat beef dry with paper towels (this is important as surface moisture will interfere with browning). Using cotton kitchen twine, tie roast as show in the photo below. Sprinkle with salt and pepper on all sides.
Place pancetta into a Dutch oven and cook, stirring occasionally, until crisp. When crisp, remove with a slotted spoon to a paper towel lined plate; set aside.
Add the prepared chuck roast to the pot and cook until well browned on both sides. Transfer to a large plate; set aside.
Add the onions, carrots, celery, and tomato paste to the pot, sauteing and stirring occasionally, until the vegetables begin to soften and brown. Add the garlic, sugar, flour, and the crisp pancetta. Cook, stirring constantly until well combined and fragrant. Add wine, chile peppers, and tomatoes; stir with a wooden spoon to release the browned bits on the bottom of the pan. Add the thyme sprig, thyme leaves, and rosemary sprig.
Return the browned chuck roast and any accumulated juices to the pot. Bring just to a boil and then remove from heat. Cover with a lid and place in the oven.
Using oven-safe glove and tongs, turn the meat every 45 minutes, and cook until the meat is fork tender and almost falling apart, approximately 3 hours.
After approximately 3 hours, check the internal temperature of the beef with your meat thermometer. When the internal temperature registers 180 degrees F. on your thermometer, remove from the oven.
When the meat is done cooking, remove from the oven, and transfer the meat to a cutting board. Cover with aluminum foil to keep warm and let the meat rest approximately 15 minutes for juices to settle and cool a little.
Using a wide shallow spoon, skim the fat off the surface of the cooking braising sauce. Stir in the fresh parsley leaves.
After resting, slice the roast and serve with the braising liquid and vegetables.
Do not waste the extra braising sauce - You will have lots of braising sauce left from this dish. Place the sauce into the refrigerator ernight and then remove the rest of the congealed fat the next day. This delicious sauce can be used as a soup base, pasta base, or used to cook chicken pieces in and then served over pasta. Karen likes to use the leftover braising sauce in her Tuscan Frittata with Two Cheeses.
* Cabernet Sauvignon wine may be substituted.
