Apple Crisp with Oats

Apple crisp with oats was the first dessert I ever made all by myself and I still remember how proud I was. I didn’t have to worry about making a pie crust or rolling dough, just slice the apples and mix up a buttery topping with oats. The result was magic: juicy, spiced apples bubbling under a golden, crispy oat topping that made the kitchen smell like autumn in a pan.

Now it’s one of my most trusted recipes when I want something comforting, simple, and crowd-pleasing. Whether it’s a Sunday dinner or a holiday table, this crisp never fails to impress without requiring much effort. The oats give it that perfect crunch while the apple filling stays warm, soft, and just the right amount of sweet. And of course, it’s even better with a dollop of whipped cream or a scoop of vanilla ice cream on top.

Ingredients

Here’s what I use for this recipe. You can always make substitutions if you prefer!

• Apples – The star of the show, sliced thin for a soft and juicy filling.
• Brown sugar – Adds sweetness and depth to both the apples and the crisp topping.
• Granulated sugar – Balances the tartness of the apples with extra sweetness.
• Lemon juice – Brightens the apple flavor and keeps them from browning.
• Cinnamon – The essential spice that gives that classic apple crisp flavor.
• Nutmeg (optional) – Adds warmth and extra depth.
• Old-fashioned oats – Provide the signature crunchy texture in the topping.
• All-purpose flour – Helps bind the topping and gives it a crumbly bite.
• Butter – Creates a rich, golden topping when melted into the oats and flour.
• Salt – Enhances all the sweet and spiced notes in both layers.

Tools You’ll Need

• 9×13 baking dish – Large enough to hold the apple filling and crisp topping evenly.
• Mixing bowls – One for the apples and one for the crisp topping.
• Apple peeler or paring knife – To prep the apples quickly and efficiently.
• Cutting board – For slicing apples evenly.
• Measuring cups and spoons – For precision when mixing the topping.
• Spatula or spoon – To toss the apples with sugar and lemon and layer everything together.
• Oven mitts – For safely removing the hot and bubbly crisp from the oven.

Instructions

Step 1:

I preheat the oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.

Step 2:

I peel, core, and slice the apples thinly, then toss them in a bowl with lemon juice, granulated sugar, brown sugar, cinnamon, and a pinch of nutmeg. I spread the apple mixture evenly into the baking dish.

Step 3:

In another bowl, I mix together the oats, flour, brown sugar, cinnamon, and salt. Then I add the melted butter and stir until the mixture becomes crumbly and well combined.

Step 4:

I sprinkle the oat topping evenly over the apples, covering them completely without pressing it down too firmly.

Step 5:

I bake the apple crisp for 45–50 minutes, or until the top is golden and crisp and the apples are bubbling underneath.

Step 6:

Once baked, I let it cool for about 10–15 minutes before serving to allow the filling to set slightly.

Tips

I like using a mix of apples like Granny Smith and Honeycrisp for a balance of tart and sweet.

If I want a thicker filling, I add a tablespoon of cornstarch to the apple mixture.

I toast the oats slightly before mixing if I want an even nuttier flavor.

This crisp is great reheated just pop it in the microwave for a warm, comforting treat.

You can make it gluten-free by using certified GF oats and a 1:1 gluten-free flour.

Ways to Serve

I always serve this warm with a scoop of vanilla ice cream it’s a classic for a reason.

A drizzle of caramel sauce or maple syrup takes it to the next level.

For breakfast, I’ll even eat a small bowl with a spoonful of Greek yogurt.

It pairs beautifully with spiced tea or hot apple cider.

Frequently Asked Questions

Can I make Apple Crisp with Oats ahead of time?

Yes and I often prep it the night before and store it in the fridge. I bake it fresh the next day or reheat before serving.

Can I use quick oats instead of old-fashioned oats?

You can, but I find old-fashioned oats give a better texture. Quick oats tend to soften more and don’t crisp up as well.

What’s the best type of apple to use?

I like to use a combination Granny Smith for tartness and Fuji or Honeycrisp for sweetness. This balance makes the filling rich and flavorful.

Can I freeze leftover apple crisp?

Yes and I freeze cooled portions in airtight containers. Reheat in the oven or microwave when ready to enjoy again.
