Instructions

  1. Step 1: Finely dice 1 medium apple (skin on) and toast 1/4 cup chopped walnuts in a dry skillet over medium heat for 3 minutes until fragrant, then set aside.
  2. Step 2: Combine 1 cup old-fashioned oats, 2 cups almond milk, 1 tbsp brown sugar, 1 tsp cinnamon, and a pinch of salt in a saucepan. Bring to a gentle simmer over medium heat, stirring constantly.

  4. Step 4: Stir in the diced apple and cook for 2 more minutes until apples are tender but not mushy. Remove from heat, then mix in 2 tbsp maple syrup and the toasted walnuts.
  5. Step 5: Serve warm in bowls, ensuring each portion has a balanced mix of oats, apples, and walnuts.

How do I store leftover Williams-Style Apple Cinnamon Oatmeal with Walnuts?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat in the microwave or oven; egg- or grain-based items may need a splash of milk or water to refresh texture. Cold-served items (overnight oats, smoothies) keep 2–3 days in the fridge.

Can I substitute ingredients in Williams-Style Apple Cinnamon Oatmeal with Walnuts?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut).

The recipe is written for 2 servings. Multiply each ingredient by (your serving target / 2). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
