Why You’ll Love Hearty Apple Walnut Steel-Cut Oats Ready in 30 Minutes

I enjoy this recipe because it’s wholesome, simple, and keeps me full for hours. I like how it balances nutrition and flavor without feeling heavy. It’s a warm, reliable breakfast that feels especially comforting on busy mornings or cooler days.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

1 cup steel-cut oats
2 cups water
1 cup milk (or plant-based alternative)
1 apple, diced
1/4 cup walnuts, chopped
1 tbsp honey or maple syrup
1/2 tsp cinnamon
Pinch of salt

Directions

I start by bringing the water and milk to a boil in a saucepan over medium heat. Once it’s boiling, I add the steel-cut oats and reduce the heat to a gentle simmer.

I let the oats cook for about 20 minutes, stirring occasionally so they don’t stick to the bottom. After that, I stir in the diced apple, cinnamon, and a pinch of salt.

I continue cooking for another 10 minutes until the oats are tender and creamy and the apples are soft. Once done, I remove the pot from the heat and stir in the chopped walnuts and sweetener.

I serve the oats warm and enjoy them right away.

Servings and Timing

I usually get 2 servings from this recipe. It takes about 5 minutes to prep and roughly 30 minutes to cook, making the total time around 35 minutes.

Variations

I sometimes use pears instead of apples for a different flavor. When I want extra richness, I add a splash more milk at the end. I also enjoy topping the oats with raisins, flaxseed, or an extra drizzle of honey.

Storage/Reheating

I store leftover oats in an airtight container in the refrigerator for up to 3 days. To reheat, I warm them on the stovetop or in the microwave with a splash of milk to loosen the texture.
