Shopping List

• Old-fashioned rolled oats (avoid instant; steel-cut requires longer cooking)
• Apple (Honeycrisp, Fuji, or Gala for sweetness; Granny Smith for tartness)
• Walnuts (raw or lightly toasted)
• Unsweetened milk (almond, oat, dairy, or cashew; water works in a pinch)
• Water
• Ground cinnamon
• Ground nutmeg (optional but lovely)
• Pure maple syrup or raw honey (optional, to taste)
• Vanilla extract (optional)
• Pinch of sea salt
• Chia seeds or ground flaxseed (optional for extra fiber and omega-3s)
• Raisins (optional for a touch of chew and sweetness)

Step-by-Step Instructions

1. Prep your apple: Core and dice 1 medium apple into small cubes. Leave the skin on for extra fiber and color.
2. Toast the walnuts: In a dry skillet over medium heat, toast 1/4 cup chopped walnuts for 2–3 minutes until fragrant.

   Set aside. This step deepens the flavor.

3. Warm the base: In a small pot, combine 1 cup unsweetened milk and 1/2 cup water. Add a pinch of sea salt.

   Bring to a gentle simmer over medium heat.

4. Cook the apples: Stir in the diced apple, 1/2 teaspoon cinnamon, and a pinch of nutmeg. Simmer for 2–3 minutes, just until the apples soften slightly.
5. Add the oats: Pour in 1 cup rolled oats. Reduce heat to medium-low and cook, stirring occasionally, for 5–7 minutes until creamy and thickened.

   If you like it thinner, add a splash more milk or water.

6. Flavor boost: Stir in 1/2 teaspoon vanilla extract, 1–2 teaspoons maple syrup (or to taste), and 1 tablespoon chia seeds or ground flax, if using. Cook 1 more minute.
7. Finish and serve: Remove from heat. Fold in half the toasted walnuts and a small handful of raisins, if you like.

   Spoon into bowls and top with the remaining walnuts and a sprinkle of cinnamon.

How to Store

• Refrigerate: Store leftovers in an airtight container for up to 4 days. Add a splash of milk when reheating to loosen it up.
• Freeze: Portion into single-serve containers and freeze for up to 2 months. Thaw in the fridge overnight, then warm on the stove or in the microwave with extra liquid.
• Meal prep tip: Cook a big batch on Sunday, then portion into jars.

  Add toppings right before eating to keep the walnuts crunchy.

Why This is Good for You

• Steady energy: Rolled oats provide complex carbs and soluble fiber, which help keep blood sugar steady and hunger in check.
• Heart-healthy fats: Walnuts offer plant-based omega-3s that support brain and heart health.
• Nutrient-dense: Apples bring vitamin C and fiber. Cinnamon may help with balanced blood sugar when paired with a wholesome meal.
• Protein options: Using dairy milk or adding a spoon of yogurt on top can boost protein, making this bowl more satisfying.

What Not to Do

• Don’t use instant oats if you want the best texture. They can turn mushy and bland.
• Don’t skip the pinch of salt. It doesn’t make the oatmeal salty; it brings out the apple and cinnamon flavors.
• Don’t over-sweeten. Start with a small amount of maple syrup.

  The apple and raisins already add natural sweetness.

• Don’t burn the nuts. Toast on medium heat and watch closely. Burnt walnuts taste bitter and overpower the bowl.
• Don’t walk away while it cooks. Oatmeal thickens fast, and a minute too long can make it gluey. Stir occasionally.

Variations You Can Try

• Skillet caramelized apples: Sauté the apple in a teaspoon of coconut oil with cinnamon before adding to the pot for deeper flavor.
• Protein boost: Stir in a scoop of unflavored or vanilla protein powder at the end with a little extra liquid.
• Spice swap: Use apple pie spice or add cardamom for a brighter, more aromatic twist.
• No nuts: Swap walnuts for pumpkin seeds or sunflower seeds for a nut-free crunch.
• Steel-cut version: Use 1/2 cup steel-cut oats with 2 cups liquid and cook 20–25 minutes.

  Add apples in the last 10 minutes.

• Overnight option: Combine oats, milk, cinnamon, diced apples, walnuts, and chia in a jar. Chill overnight. Eat cold or warm with a splash of milk.
• Creamy finish: Stir in a spoon of plain Greek yogurt or coconut yogurt right before serving.

FAQ

Can I make this without any added sweetener?

Yes.

Use a sweeter apple like Honeycrisp and add raisins. You can also cook the apples a little longer to concentrate their natural sugars.

What’s the best milk to use?

Any unsweetened milk works. Almond milk keeps it light, oat milk makes it extra creamy, and dairy milk adds protein and richness.

Can I make it in the microwave?

Yes.

Combine oats, milk, water, salt, spices, and apples in a large microwave-safe bowl. Cook 2–3 minutes, stir, then cook another 1–2 minutes until thick. Stir in walnuts and extras at the end.

How can I prevent oatmeal from sticking to the pot?

Use medium-low heat, stir often, and don’t skimp on liquid.

A nonstick saucepan or a quick spritz of oil can help if your pot tends to stick.

Is this gluten-free?

Oats are naturally gluten-free, but choose certified gluten-free oats if you’re sensitive or have celiac disease, due to potential cross-contact during processing.

Can I double the recipe?

Absolutely. Double everything and use a larger pot. Cooking time stays about the same; just stir more often.

What apples hold up best?

Honeycrisp, Fuji, and Pink Lady stay firm with good sweetness.

Granny Smith holds shape well and adds a nice tart contrast.
