Ingredients You’ll Need

Every ingredient in Grandma’s Apple Crisp is simple but purposeful, working together to create that classic taste and irresistible texture. Using the best versions you can find is key, and each item adds its own special flair to the final masterpiece.

• Granny Smith or Honeycrisp apples (6 cups, peeled and sliced): These varieties give the perfect tartness and hold their shape as they bake.
• Granulated sugar (2 tablespoons): Adds just enough sweetness to bring out the apples’ natural flavor without making the filling too sugary.
• Ground cinnamon (1 teaspoon, plus 1 teaspoon for topping): A warming spice that brings depth and comfort to both the apples and the crumbly topping.
• Ground nutmeg (1/2 teaspoon): Just a touch gives the filling a subtle, earthy undertone.
• Lemon juice (1 tablespoon): Brightens the filling, keeping the apples lively and preventing them from turning brown.
• All-purpose flour (3/4 cup): The backbone of the topping—gives body and structure to those delicious crumbles.
• Old-fashioned oats (3/4 cup): For a wholesome chew and that signature crisp, make sure these are not the quick-cook kind.
• Packed brown sugar (1/2 cup): Lends warmth and a caramel-like depth to the topping.
• Granulated sugar (1/4 cup for topping): Balances out the sweetness for a crisp finish.
• Ground cinnamon (1 teaspoon for topping): This extra hit in the topping carries the spice all the way through.
• Salt (1/4 teaspoon): Just enough to sharpen and enhance all the other flavors.
• Unsalted butter (1/2 cup, cold and cubed): The secret to crispy, buttery crumbs; make sure it’s straight from the fridge before you start.

How to Make Grandma’s Apple Crisp

Step 1: Prep Your Baking Dish and Oven

Start by preheating your oven to 350°F—this gives you plenty of time to get your ingredients ready while it heats. Grab a 9×9-inch baking dish (or one similar in size) and give it a light greasing with butter or nonstick spray. This step prevents sticking and ensures your apple crisp serves up easily and neatly later on.

Step 2: Make the Apple Filling

In a large bowl, combine your peeled and sliced apples with granulated sugar, cinnamon, nutmeg, and a splash of lemon juice. Toss everything together until the apples are evenly coated. This mixture is where Grandma’s Apple Crisp really gets its personality—the lemon juice keeps things fresh, while the spices and sugar create the base for an irresistible, gooey filling. Once mixed, spread the apple layer out evenly in your prepared baking dish.

Step 3: Prepare the Crisp Topping

Now for the fun part! In another bowl, stir together your flour, oats, brown sugar, granulated sugar, cinnamon, and salt. Drop in the cold cubes of butter, and use a pastry cutter, fork, or even your fingers to work the butter in, squeezing and mixing until the topping forms coarse, pebble-sized crumbs. The result should be crumbly and a little clumpy—just like Grandma’s Apple Crisp should be! This texture is what transforms into a golden, crunchy topping in the oven.

Step 4: Assemble and Bake

Sprinkle the crumble topping evenly over your apple mixture, making sure to cover every bit of fruit for maximum flavor and crunch. Slide your baking dish onto the center rack of your preheated oven. Bake for 40–45 minutes, until the topping is deeply golden and the apples below are bubbling and fragrant. If you peek in and see the top browning too quickly, you can loosely tent it with foil for the last few minutes.

Step 5: Cool and Serve

Once baked, let Grandma’s Apple Crisp cool on a wire rack for at least 10–15 minutes. The filling will thicken as it sits, and serving it warm means you’ll get the best of both molten apples and crispy topping. When you scoop it out, listen for the crackle of crust—you’ll know you nailed it!

How to Serve Grandma’s Apple Crisp

Garnishes

Sometimes the simplest touch makes all the difference. A scoop of creamy vanilla ice cream gently melting over a warm bowl of Grandma’s Apple Crisp is pure nostalgia. A dollop of lightly whipped cream, a dusting of cinnamon, or a sprinkle of chopped toasted pecans or walnuts brings added flourish and crunch.

Side Dishes

If you’re serving Grandma’s Apple Crisp at a dinner party or holiday gathering, pair it with a mug of hot spiced cider or a cup of strong coffee for the ultimate cozy pairing. For a lighter touch, offer an assortment of fresh berries on the side to balance out the sweetness.

Creative Ways to Present

Try baking individual portions in small ramekins or mason jars for a special dinner party twist. For brunch, layer spoonfuls of Grandma’s Apple Crisp with yogurt in parfait glasses. You can even use it as a decadent topping for pancakes or waffles—just spoon the warm crisp right over and drizzle with a little maple syrup.

Make Ahead and Storage

Storing Leftovers

Have extra Grandma’s Apple Crisp? Store any cooled leftovers in an airtight container in the refrigerator for up to four days. The flavors will deepen, and a second-day serving can be even more delicious as the juices settle and the spices mingle.

Freezing

You can freeze Grandma’s Apple Crisp fully baked or unbaked. If freezing after baking, let it cool completely, then wrap the dish tightly in plastic wrap and foil. For best results, consume within three months. If prepping ahead, assemble the crisp (without baking), wrap well, and freeze. Bake straight from the freezer, adding 10–15 minutes to the bake time.

Reheating

To bring Grandma’s Apple Crisp back to its glorious just-baked state, reheat individual portions in the microwave for 30–60 seconds, or warm the whole dish in a 350°F oven for about 15 minutes, until bubbling and crisp again. Cover loosely with foil if needed to prevent over-browning.

FAQs
