Ingredient Swaps
Life happens, and sometimes you don’t have exactly what the recipe calls for. No worries! Here are some swaps:
- Veal shanks → Beef shanks, lamb shanks, or pork shanks (slightly longer cook times for beef).
- Vermouth or white wine → Chicken broth with 1 tablespoon lemon juice or apple cider vinegar.
- Crushed tomatoes → Tomato sauce or diced tomatoes blended smooth.
- Fresh herbs → 1 teaspoon dried herbs for each tablespoon of fresh.
Helpful Tips
- Brown meat well: Don’t skip this-it adds layers of flavor.
- Low and slow: The longer you cook at low heat, the more tender and flavorful the meat.
- Don’t lift the lid: Opening the slow cooker lets heat escape and can increase cooking time.
- Skim excess fat: After cooking, skim the top of the sauce if you prefer a leaner finish.
- Make ahead: Osso Bucco often tastes even better the next day after the flavors have melded.
Customization Ideas
- Spicy kick: Add a pinch of red pepper flakes when sautéing vegetables.
- Earthy twist: Stir in mushrooms during the last hour of cooking.
- Creamy finish: Swirl in a tablespoon of mascarpone or cream just before serving.
- Herb variations: Experiment with rosemary, sage, or oregano instead of thyme.
- Different garnishes: Try toasted pine nuts, fried sage leaves, or a drizzle of aged balsamic.
