Ingredients

1 cup old-fashioned rolled oats (do not use instant oats, they get too mushy)
1 cup milk of your choice (dairy milk, almond milk, oat milk, or any plant-based milk all work great)
1/2 cup plain Greek yogurt (use dairy-free yogurt to keep it vegan)
2 tablespoons pure maple syrup (honey or agave syrup can be substituted)
1/2 teaspoon vanilla extract
1/4 teaspoon cinnamon
1/4 teaspoon salt
1/3 cup chopped walnuts (pecans work as a great substitute)
1 tablespoon chia seeds (optional, but adds thickness and extra fiber)
Fresh banana slices or apple chunks for topping (optional)

How to Make Maple Walnut Overnight Oats

Grab two mason jars or airtight containers that hold at least 16 ounces each. This gives the oats plenty of room to expand as they soak.
Add the rolled oats, chia seeds, cinnamon, and salt to each jar, dividing the ingredients evenly between the two containers.
Pour in the milk and add the Greek yogurt to each jar. Stir everything together really well so there are no dry clumps of oats at the bottom.
Drizzle in the maple syrup and vanilla extract. Give it another good stir to make sure the sweetener is fully mixed throughout.
Seal the jars with lids and place them in the refrigerator. Let them soak for at least 6 hours, but overnight works best for the creamiest texture.
In the morning, take the jars out of the fridge and give the oats a good stir. If they look too thick for your taste, just splash in a little extra milk and stir again.
Top with the chopped walnuts and any fresh fruit you like. Drizzle on a little extra maple syrup if you want extra sweetness, then enjoy!

Pro Tips for Perfect Maple Walnut Overnight Oats

Use old-fashioned oats: Quick oats turn too soft and mushy overnight, while steel-cut oats stay too firm. Old-fashioned rolled oats hit the perfect creamy and chewy balance.
Add walnuts right before eating: Stirring the walnuts in the night before can make them soft and lose their crunch. Add them fresh in the morning so every bite stays satisfying.
Toast your walnuts first: Spread them on a dry skillet over medium heat for 3 to 4 minutes until fragrant. Toasted walnuts have a deeper, nuttier flavor that really elevates this recipe.
Adjust the liquid to your liking: Some people love thick oats, and others prefer a looser, more pourable consistency. Start with the recipe as written and tweak the milk amount to match your preference next time.
Do not skip the salt: Just a small pinch of salt might seem odd in a sweet dish, but it actually balances all the flavors and makes the maple and walnut taste even better.

Flavor Variations

Maple Banana Walnut: Mash half a ripe banana right into the oat mixture before refrigerating. It adds natural sweetness and a thick, creamy texture that pairs beautifully with the maple syrup.
Apple Cinnamon Maple Walnut: Stir in 1/4 cup of finely diced apple and increase the cinnamon to 1/2 teaspoon. It tastes just like a slice of apple walnut pie for breakfast.
Chocolate Maple Walnut: Mix in 1 tablespoon of unsweetened cocoa powder and a tablespoon of mini chocolate chips. It is like dessert for breakfast in the best possible way.
Pumpkin Maple Walnut: Stir in 3 tablespoons of pumpkin puree and a pinch of pumpkin pie spice. This version is perfect for fall and tastes incredibly warm and cozy.

Storage Tips

Store your maple walnut overnight oats in sealed jars or airtight containers in the refrigerator for up to 5 days. This makes them ideal for weekly meal prep since you can make a big batch on Sunday and grab one every morning without any extra effort. Just remember to add the walnut topping fresh each day so they stay crunchy.

If you want to freeze them, spoon the oat mixture (without toppings) into freezer-safe containers and freeze for up to 3 months. Thaw overnight in the refrigerator and stir well before eating. The texture may be slightly softer after freezing, but they still taste great with fresh toppings added right before serving.

Frequently Asked Questions

Can I make maple walnut overnight oats without yogurt?

Yes, you can leave out the Greek yogurt if you prefer. Just replace it with an equal amount of extra milk. The oats will be a little less thick and creamy, but they will still taste delicious.

How long do overnight oats need to soak?

Overnight oats need at least 6 hours in the refrigerator to soften properly. Letting them soak for 8 hours or overnight gives you the best creamy texture. Do not rush the soaking time or the oats will still feel too firm to enjoy.

Are maple walnut overnight oats healthy?

Yes, they are a very nutritious breakfast option. Rolled oats provide complex carbs and fiber, walnuts add healthy fats and omega-3s, and Greek yogurt delivers a good amount of protein. Pure maple syrup is used as a natural sweetener in a small amount, making this a wholesome and balanced meal.

Can I eat overnight oats warm?

Absolutely! If you prefer a warm breakfast, just scoop the oats into a microwave-safe bowl and heat for 60 to 90 seconds, stirring halfway through. Then add your walnut topping and any other toppings you like before eating.

What kind of oats work best for overnight oats?

Old-fashioned rolled oats are the best choice for overnight oats. They absorb the liquid at just the right rate and give you a creamy but slightly chewy texture. Instant oats get too mushy and steel-cut oats stay too hard unless you soak them for a very long time.
