Instructions

1. Step 1: In a large pot, melt 2 tbsp unsalted butter over medium heat. Add 2 large sliced leeks (white and light green parts only) and sauté gently for 6-8 minutes until soft and fragrant but not browned.
2. Step 2: Add 1 medium peeled and diced potato, 3/4 cup rolled oats, and 1 tsp fresh thyme leaves to the pot. Stir to combine.
3. Step 3: Pour in 4 cups chicken or vegetable stock, then season with 1 tsp sea salt and 1/2 tsp freshly ground black pepper. Bring the mixture to a boil, then reduce heat to low and simmer gently for 25 minutes until the potato and oats are tender.
4. Step 4: Remove the soup from heat and use an immersion blender to puree until smooth but still slightly textured. Stir in 1/2 cup whole milk or cream for richness and reheat gently if needed. Serve hot with crusty bread.
