Step 1: Brown the venison
- Preheat your oven to 160°C (320°F). Toss the venison pieces in flour, shaking off any excess. Heat olive oil in a large frying pan over medium heat. Brown the venison in batches, making sure all sides are seared. Set aside the browned venison.
Step 2: Sauté the vegetables
- In the same pan, add the chopped onions, carrots, celery, and garlic. Sauté for 5-7 minutes until softened and lightly browned. Stir in the tomato paste and cook for an additional 1-2 minutes to bring out the flavor.
Step 3: Deglaze the pan
- Pour in the red wine and scrape up any browned bits from the bottom of the pan. Let the wine simmer for 2-3 minutes to reduce slightly.
Step 4: Combine and slow cook
- Transfer the venison and sautéed vegetables to the casserole dish. Add the bay leaves, thyme, and beef stock. Stir everything together, making sure the venison is submerged in the liquid. Cover the dish and place it in the preheated oven. Cook for 2-2.5 hours, or until the venison is tender.
Step 5: Season and serve
- After cooking, remove the casserole from the oven and discard the bay leaves and thyme sprigs. Season with salt and pepper to taste. Serve the Mary Berry Venison Casserole hot, garnished with fresh parsley if desired.
