Easy Apple Crisp

I’m always on the lookout for easy dessert recipes, and I really developed a taste for crisps, crumbles, and cobblers when I lived in Florida. 

As a fun aside, it is the one state that is in the South but is not considered Southern. Go figure! 

That doesn’t mean that they don’t love them some crisps and cobblers like most other Southern states. You can see why I fell in love with them during my time there!

I usually make my easy apple crisp with Golden Delicious apples because they bake so well. This time, I decided to try some delicious Honeycrisp apples instead. 

And as soon as I tasted this apple crisp recipe with oats, I knew I had to share it with all of you!

Ingredient Notes and Substitutions

• Honeycrisp Apples – You can technically use any type of apple that you want for this old fashioned apple crisp recipe. 
  
  But, I have to say… I think that Honeycrisp is the tastiest! If you do opt to use other varieties, a mix of tart and sweet is your best bet.
  
• Sugar – You’ll need granulated sugar for the easy apple crisp filling, and brown sugar for the topping.
  
• All-Purpose Flour – I use flour as a thickening agent in the filling. You could also replace with cornstarch if you’d like.
  
• Old-Fashioned Oats – The key to a crispy and crunchy topping! Use old-fashioned oats — not instant — for the ideal texture.
  
• Butter – For your topping as well! Butter helps form the crumble layer of this dessert while also adding flavor.
  
• Cinnamon – It wouldn’t be an easy apple crisp recipe without cinnamon! You’ll use it in the filling and topping.
  
• Walnuts – A fun extra for the crumble! Walnuts add crunch and a touch of earthy flavor.

Easy Apple Crisp Recipe Tips and Tricks

• Slice the apples thin.

Every apple crisp recipe is different. Some require peeled apples, others don’t. Some ask you to cube or dice your fruit, while others (like mine) call for thinly sliced apples. 

They’ll cook evenly and will soften more easily that way.

• Don’t forget to add a bit of lemon juice.

Did you scratch your head when you saw lemon juice on the recipe card for this apple crisp recipe with oats?

If you did, you probably don’t know that citrus juice helps prevent fruit from turning brown. It also adds a subtle hint of bright flavor to this easy apple crisp recipe!

• Use very cold butter.

Don’t take the butter out of the fridge until you’re ready to add it to the topping. In fact, freezing it may be even better!

Using very cold butter will create a delightfully crispy crumble. 

Warm or room temperature will cause the topping to spread and/or go flat… which you definitely don’t want!

Storing and Reheating Leftover Old Fashioned Apple Crisp

Let leftovers cool completely before storing them in an airtight container in the fridge. 

This easy apple crisp will keep for up to 3-4 days, but keep in mind that the texture will change over time.

Reheat single servings in the microwave in 30-second bursts until heated through. 

Or, preheat your oven to 350°F to reheat larger portions. Bake for about 15 minutes, or until warm.

Kitchen Tools You Will Need

Ingredients

 

1x2x3x

Apple Mixture Ingredients:

• ▢ 4-6 thinly sliced apples, a mix of tart and sweet, adding up to 7 cups of sliced apples
• ▢ 1/4 cup granulated sugar
• ▢ 2 tablespoons all-purpose flour
• ▢ 1 teaspoon lemon juice
• ▢ 1 teaspoon ground cinnamon

Topping Ingredients:

• ▢ 1 cup old fashioned oats
• ▢ 1/2 cup all-purpose flour
• ▢ 1/3 cup packed brown sugar
• ▢ 1/4 cup chopped walnuts
• ▢ 1 teaspoon cinnamon
• ▢ 1/2 cup butter, diced

Instructions

 

• Preheat the oven to 350 degrees.
• Peel your apples and then thinly slice them. Use a mixture of tart and sweet apples. I started with 4 apples and then peeled and sliced one more at a time until I filled 7 cups of sliced apples.
• In a large bowl, toss the apple slices in the all-purpose flour, sugar, lemon juice and cinnamon.
• In another medium bowl, combine the old-fashioned oats, flour, brown sugar, walnuts, and cinnamon. Cut the stick of butter into cubes. Cut them into the oatmeal mixture until they form a crumble using a fork or a dough cutter.
• Spray an 8×8 dish with nonstick cooking spray. Pour in your apples and then top with the oatmeal mixture. Gently spread it to make sure the oats are even.
• Bake for 40-45 minutes. The top will be golden brown, and the sides will be bubbly.
