Season the wild boar meat with salt and pepper, then brown it in batches over high heat.
In a large stew pot or Dutch oven, sauté onions until translucent. Add carrots and cook for 3 minutes more.
Place browned wild boar into the pot along with bacon lardons (if using), then stir in tomato paste to form an even mixture over medium heat.
Pour beef or game stock, dissolved cube included. Add thyme and bring to a simmer.
Cover tightly
reduce heat slightly so the stew is at just below boiling point (a light bubble every now and then)
Cook for 1-2 hours on low until meat falls off the bone, checking occasionally that liquid remains. Adjust seasoning as necessary.
Shred cooked wild boar using two sharp knives or a fork.
Serve hot with fresh bread and enjoy your gamey feast!
