Apple crisp is the dessert I make when I want the house to smell like I have my life together. It is cozy, low drama, and basically impossible to mess up if you taste the apples and pay attention to the topping texture.

This classic version keeps things accessible: real apples, a bright hit of lemon, cinnamon warmth, and an oat crumble that bakes into crisp edges and buttery pockets. No fussy pie crust, no gadgets, just a baking dish and a spoon. If you want it extra special, serve it warm with vanilla ice cream and watch it do that melty, creamy thing that feels like a reward.

Why It Works

  • Apples that stay tender, not mushy: A mix of apple varieties and a little lemon juice keeps the filling lively and balanced.
  • Crunchy, golden topping: Brown sugar plus oats and cold butter create those crisp edges and buttery crumble clusters.
  • No soggy bottom: A touch of flour or cornstarch thickens the juices so you get spoonable sauce, not apple soup.
  • Make it your way: Easily adjust sweetness based on your apples, or add nuts if you want extra crunch.

Storage Tips

Refrigerator: Cover the baking dish or transfer to an airtight container. Store for up to 4 days.

Freezer: Freeze tightly wrapped portions for up to 2 months. Thaw overnight in the fridge before reheating for best texture.

Reheating tips:

  • Oven (best for crisp topping): Warm at 350°F (175°C) for 12 to 18 minutes, uncovered, until hot and crunchy again.
  • Microwave (fast): 30 to 60 seconds per serving. The topping will soften, so if you care about crunch, finish it in a toaster oven for a few minutes.

Common Questions

What are the best apples for apple crisp?

You want apples that hold their shape and taste like apples after baking. My favorite mix is Granny Smith for tartness plus Honeycrisp or Gala for sweetness. If you only have one type, go for Honeycrisp or Granny Smith and adjust sugar to taste.

Do I need to peel the apples?

Peeling is optional. Peeled apples give a softer, more classic texture. Unpeeled apples add a little chew and color. If your apple skins are thick or waxy, I peel them.

How do I keep the topping crunchy?

Use cold butter and bake uncovered. If your kitchen is warm, pop the prepared topping in the fridge for 10 minutes before sprinkling it on. Also, do not overmix it. You want crumbly bits, not a paste.

Can I make apple crisp ahead of time?

Yes. You can assemble it up to 1 day ahead and refrigerate, covered. Just know the topping can soak up some moisture and lose a little crunch. For the crispest results, store the topping and apples separately, then combine right before baking. If baking straight from the fridge, add 5 to 10 minutes to the bake time.

Why is my crisp watery?

Usually it is one of three things: very juicy apples, not enough thickener, or it was served too soon. Let it rest 15 to 20 minutes after baking so the juices settle and thicken.

Flour or cornstarch, which should I use?

Either works. Flour gives a slightly softer, more “cozy” thickness. Cornstarch tends to set a bit more and look glossier. If your apples are extra juicy, lean toward cornstarch or add a touch more thickener.

This is the dessert I make when I want something homemade but I do not want to negotiate with pie dough. The first time I made apple crisp on my own, I learned two important truths: one, you can fix almost anything with a little more salt and lemon. Two, the best bites are always the ones along the edge of the pan where the topping gets extra crisp and the apples caramelize just a bit. Now I make it like I am cooking for friends in my kitchen, which means I taste the apples, adjust the cinnamon until it makes sense, and absolutely call dibs on the corner piece.
