Ingredients You’ll Need

Apples

• 6 cups apples, peeled, cored, and sliced about 1/4 inch thick
  • Use firm baking apples like Honeycrisp, Granny Smith, Braeburn, or Fuji.
  • Mix sweet and tart apples for deeper flavor and better texture.

Apple filling

• 1/3 cup granulated sugar
• 1/3 cup light brown sugar, packed
• 2 tablespoons all-purpose flour
• 1 teaspoon ground cinnamon
• 1/4 teaspoon ground nutmeg
• 1/4 teaspoon ground ginger (optional for a little warmth)
• 1/4 teaspoon fine sea salt
• 2 teaspoons lemon juice or apple cider vinegar
• 1 teaspoon vanilla extract
• 2 tablespoons melted butter, salted or unsalted

Notes:

• Use coconut sugar instead of brown sugar if you prefer.
• Swap all-purpose flour with cornstarch (1 tablespoon) for a gluten-free option.

Crunchy topping

• 3/4 cup old-fashioned rolled oats
• 1/2 cup all-purpose flour
• 1/2 cup light brown sugar, packed
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon fine sea salt
• 1/3 cup cold butter, cut into small cubes
• 1/3 cup chopped pecans or walnuts (optional but highly recommended)

Shortcuts and brand notes:

• Use pre-sliced apples from the produce section when you feel short on time.
• Use gluten-free oat and flour blends if you cook for gluten-sensitive guests.
• Any supermarket butter works, but higher-fat European-style butter gives a richer topping.

Optional add-ins

• 1/3 cup raisins or dried cranberries
• 1/4 cup caramel sauce for drizzling after baking
• 1/4 teaspoon almond extract for a bakery-style twist

Equipment list

• 9×9 inch or similar 2 quart baking dish
• Large mixing bowl
• Medium mixing bowl
• Measuring cups and spoons
• Sharp knife and cutting board or apple slicer
• Rubber spatula or wooden spoon
• Pastry cutter or clean hands for the topping

Tips & Tricks

• Slice apples evenly so they cook at the same rate and stay tender, not mushy.
• Toss apples with lemon juice right away to keep them from browning.
• Use a mix of tart and sweet apples for better flavor than a single variety.
• Keep topping butter cold so it bakes into crunchy, crumbly bits instead of melting flat.
• Taste a slice of apple with the sugar mixture before baking and adjust cinnamon or sugar to your preference.
• Do not pack the casserole too tightly; a little space lets steam escape and keeps texture pleasant.
• Place the baking dish on a sheet pan if you worry about bubbling juices.
• Cover the dish loosely with foil if the topping browns too quickly before the apples finish cooking.
• Let the casserole rest 10 minutes after baking so the juices thicken and scoops hold together.
• Add a scoop of vanilla ice cream or a spoonful of yogurt at serving time instead of baking dairy into the dish.

How to Make Easy Apple Casserole Recipe

Step 1: Prep the oven and pan

Preheat your oven to 350°F. Grease a 9×9 inch or similar 2 quart baking dish with butter or nonstick spray. Set the dish aside while you mix the filling and topping.

Step 2: Prep and season the apples

Peel, core, and slice the apples into about 1/4 inch slices. Place the slices in a large mixing bowl and drizzle on the lemon juice. Toss gently to coat all the slices.

Sprinkle in granulated sugar, brown sugar, flour, cinnamon, nutmeg, ginger, and salt. Add vanilla and melted butter, then toss until every slice looks glossy and evenly coated. Pour the apple mixture into the prepared baking dish and spread it into an even layer.

Step 3: Mix the crunchy topping

In a medium bowl, combine oats, flour, brown sugar, cinnamon, and salt. Stir until everything looks evenly mixed. Add the cold butter cubes.

Use a pastry cutter or your fingers to work the butter into the dry ingredients. Stop when the mixture forms pea-sized clumps and looks crumbly. Stir in nuts and dried fruit if you use them.

Step 4: Assemble the casserole

Sprinkle the topping evenly over the apples. Cover all the apples, but do not press the topping down too firmly. You want little peaks and valleys so the heat can circulate.

Place the baking dish on a sheet pan if you expect any bubbling. Slide the pan into the oven on the center rack.

Step 5: Bake to bubbly perfection

Bake the Easy Apple Casserole Recipe for 35 to 45 minutes. Check at 30 minutes and watch the topping color. The casserole finishes baking when the topping looks golden brown and the apple juices bubble around the edges.

Test the apples by poking a slice with a fork; it should feel tender but not fall apart. If the topping browns too much before the apples soften, tent the dish loosely with foil and keep baking until the apples reach the right texture.

Step 6: Rest and serve

Remove the casserole from the oven and place it on a cooling rack or trivet. Let it rest for about 10 minutes so the juices thicken slightly. Scoop into bowls or onto plates while still warm.

Serve plain or with vanilla ice cream, whipped cream, or a spoonful of Greek yogurt. Sprinkle on extra cinnamon if you feel fancy.

What to Serve with Easy Apple Casserole Recipe

This Easy Apple Casserole Recipe pairs nicely with breakfast favorites like scrambled eggs, turkey sausage, and fluffy pancakes. You can also serve it as a holiday side dish next to roasted turkey, ham, or pork chops. For a lighter spread, add a big green salad, roasted carrots, and a basket of warm dinner rolls.

If you lean toward dessert, serve it with vanilla ice cream, cinnamon ice cream, or a scoop of plain yogurt with a drizzle of honey. Kids usually love it with a glass of cold milk or hot cocoa.

Storage Options

• Store leftover Easy Apple Casserole Recipe in an airtight container in the fridge for up to 4 days.
• Chill the casserole completely before covering so condensation does not make the topping soggy.
• Freeze portions in freezer-safe containers for up to 2 months, and label with the date.
• Reheat single servings in the microwave in 20 to 30 second bursts until warm, then crisp the top under the broiler for 1 to 2 minutes if you like.
• Reheat a larger portion in a 325°F oven, covered with foil for 10 to 15 minutes, then uncover for 5 minutes to refresh the topping.
