Why You’ll Love This Recipe

I like this recipe because it’s quick to put together and uses basic ingredients I usually have on hand. The balance of tender apples with a crispy oat topping makes every bite satisfying. I also enjoy that it’s versatile—I can make it for weeknight desserts or bring it to family gatherings, and it’s always a hit.

Ingredients

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

6 cups tart apples (Granny Smith or Honeycrisp), peeled and sliced
1/2 cup lemon juice
1 cup old-fashioned oats
1 cup all-purpose flour
1 cup dark brown sugar
1 teaspoon cinnamon
1/2 cup unsalted butter, melted

Directions

1. I preheat the oven to 350°F (175°C).

2. In a bowl, I toss the apple slices with lemon juice and half of the brown sugar.

3. In another bowl, I mix the oats, flour, remaining brown sugar, and cinnamon. I stir in the melted butter until the mixture becomes crumbly.

4. I spread the apple mixture evenly in a baking dish and sprinkle the oat mixture over the top.

5. I bake for 35–40 minutes until the topping is golden brown and the filling is bubbly.

6. I let it cool slightly before serving, often with vanilla ice cream on top.

Servings and Timing

This recipe makes about 8 servings. The total time is 55 minutes, with about 15 minutes of prep and 40 minutes of baking.

Variations

Sometimes I add chopped walnuts or pecans to the oat topping for extra crunch. I’ve also swapped in pears or a mix of apples and berries for a different flavor. If I want a lighter version, I reduce the sugar and add a drizzle of honey instead.

Storage/Reheating

I store leftovers in the refrigerator, covered, for up to 4 days. To reheat, I warm individual portions in the microwave for 30–40 seconds or reheat the whole dish in the oven at 325°F until warmed through.

FAQs

Can I make this apple crisp ahead of time?

Yes, I assemble it in advance and bake just before serving, or I bake it and reheat later.

Do I need to peel the apples?

I prefer peeling them for a softer filling, but leaving the skin on adds extra texture and fiber.

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

Yes, but the topping will be softer and less crunchy.

Can I use butter substitutes?

Yes, plant-based butter or coconut oil works if I want a dairy-free version.

Can I freeze apple crisp?

Yes, I freeze it unbaked or baked. If unbaked, I thaw overnight before baking. If baked, I reheat straight from frozen.

What are the best apples for apple crisp?

I like Granny Smith or Honeycrisp because they hold their shape and balance sweetness with tartness.

How do I prevent the topping from getting soggy?

I bake until the top is deeply golden brown, which keeps it crisp.

Can I reduce the sugar?

Yes, I sometimes cut the sugar in half or replace part of it with maple syrup.

Can I make this gluten-free?

Yes, I substitute gluten-free flour and make sure to use certified gluten-free oats.

What can I serve apple crisp with?

I love it with vanilla ice cream, whipped cream, or even plain yogurt for breakfast.

Conclusion

This apple crisp with oats is one of my favorite desserts because it’s easy, comforting, and full of flavor. I like how versatile it is, whether I keep it classic with apples or add nuts and berries for variety. Warm, sweet, and crunchy, it’s a dish that always feels like home.
