Ingredients:
- 4 lbs (1.8 kg) beef soup bones (including marrow bones and knuckle bones)
- 1 large onion, quartered
- 2 large carrots, roughly chopped
- 2 stalks celery, roughly chopped
- 4 cloves garlic, smashed
- 1-2 tbsp apple cider vinegar (15-30 ml)
- 1-2 bay leaves
- 10 whole black peppercorns
- 1 tsp dried thyme (5 g)
- 1 tsp salt (or to taste)
- 3 cups (720 ml) of seasonal vegetables (e.g., kale, spinach, or potatoes), chopped
- Salt and pepper to taste
- Fresh herbs (e.g., parsley or chives) for garnish
Instructions:
- Rinse the soup bones under cold water. Optional: roast them in the oven for 25-30 minutes at 400°F (200°C) for enhanced flavor.
- In a large pot, add the bones, onion, carrots, celery, garlic, apple cider vinegar, bay leaves, peppercorns, thyme, and salt. Cover with cold water.
- Bring to a boil over medium-high heat. Reduce to low and simmer. Skim off any foam that rises to the top initially.
- Cook for at least 4 hours, and ideally up to 24 hours, adding water as necessary to keep bones submerged.
- Using a strainer or cheesecloth, strain the broth into another pot or container, discarding solids.
- Return strained broth to the pot. Add seasonal vegetables and cook for an additional 15-20 minutes until veggies are tender.
- Adjust seasoning with salt and pepper. Garnish with fresh herbs and ladle into bowls.
