Serves: 6
Cooking Time: 4-5 hours
Ingredients:
1 can (28 ounces) crushed tomatoes
2 cups fish stock (or vegetable stock for a milder taste)
1 cup finely chopped onion
1 cup chopped carrots
1 cup chopped celery
2 leeks (white parts only), thinly sliced
1 lb cod or halibut, cut into 1-inch cubes
1 cup 2% reduced-fat milk (or unsweetened almond milk for dairy-free)
½ teaspoon ground mace (or substitute with a pinch of nutmeg)
1 teaspoon dried thyme (or 2 teaspoons fresh thyme leaves)
½ teaspoon smoked paprika (adds depth and warmth)
Salt and white pepper, to taste
¼ cup thinly sliced green onions, for garnish
2 tablespoons chopped fresh parsley, for added freshness
Preparation:
1️⃣ Combine the base ingredients: In a slow cooker, add crushed tomatoes, fish stock, onions, carrots, celery, leeks, thyme, and smoked paprika. Stir well, cover, and cook on high for 4-5 hours until the vegetables are tender.
