Old-Fashioned Oats: Adds chew and a rustic texture to the crisp.

How To Make the Warm Grandma’s Apple Crisp

Step 1: Prepare the Apples

Peel, core, and slice the Granny Smith apples. Toss them in a mixing bowl with lemon juice, granulated sugar, and a bit of cinnamon. Spread the seasoned apple mixture evenly into a greased 9×13 baking dish.

Step 2: Mix the Topping

In another bowl, combine brown sugar, flour, oats, cinnamon, nutmeg, and salt. Add in cold cubed butter and cut it in using a pastry cutter or fork until the mixture resembles coarse crumbs.

Step 3: Assemble the Crisp

Sprinkle the oat topping evenly over the apple layer, ensuring full coverage to create that signature golden crust.

Step 4: Bake to Perfection

Place the dish in a preheated oven at 350°F (175°C) and bake for 40–45 minutes, or until the top is golden brown and the apples are bubbling underneath.

Step 5: Serve Warm

Let the crisp rest for about 10 minutes before serving. It pairs perfectly with vanilla ice cream or whipped cream.

Serving and Storing Warm Grandma’s Apple Crisp

Warm Grandma’s Apple Crisp is best served fresh out of the oven when the topping is still crisp and the apples are luxuriously tender. Pair it with a scoop of vanilla ice cream for that unbeatable hot-and-cold contrast, or drizzle on some caramel sauce if you want to take it over the top.

If you have leftovers, let the crisp cool completely before covering it with foil or transferring it to an airtight container. It can be stored in the refrigerator for up to 4 days. Reheat individual portions in the microwave or warm the entire dish in the oven at 300°F until heated through.

For longer storage, you can freeze the apple crisp after baking. Wrap tightly and freeze for up to 3 months. Thaw overnight in the fridge and reheat before serving.

Frequently Asked Questions

How do I keep the topping crispy when reheating?

Use an oven to reheat instead of a microwave. Reheat at 300°F uncovered until warm and crisp.

Can I use different apples?

Absolutely! Try Honeycrisp, Braeburn, or Fuji for a sweeter twist, or mix varieties for depth.

Can I make this apple crisp gluten-free?

Yes! Substitute the flour with a gluten-free blend and ensure your oats are certified gluten-free.

Is it okay to prep it ahead of time?

Yes. Assemble and refrigerate it unbaked for up to 24 hours. Bake when ready to serve.

What if I don’t have oats?

You can replace oats with more flour for a fine crumb texture, though it will miss the chewy bite oats provide.

Can I add nuts?

Definitely. Chopped pecans or walnuts add a great crunch to the topping.
