Ingredients of Apple Crisp with Oatmeal

• Filling:
  • 4 cups apples, peeled, cored, and sliced (Granny Smith or Honeycrisp work best, but use whatever’s in the fruit bowl)
  • 2 tablespoons granulated sugar
  • 1/2 teaspoon ground cinnamon
  • 1 teaspoon fresh lemon juice (optional, but adds brightness)
• Oatmeal Topping:
  • 3/4 cup old-fashioned oats
  • 1/2 cup all-purpose flour
  • 1/2 cup packed brown sugar
  • 1/4 teaspoon salt
  • 1/2 teaspoon ground cinnamon
  • 1/3 cup (about 5 tablespoons) unsalted butter, melted

Pro Tip for Apple Crisp with Oatmeal:

Don’t skip the oatmeal—this is what gives the topping its magical, crispy texture. If all you’ve got is quick oats, it’ll still work, but the texture won’t be quite as hearty.

Step-by-Step Instructions

I love this step-by-step because it’s so easy—plus you get to sneak a bite of apples as you work. 😉

Step 1: Prep the Apples

1. Peel and slice apples. Aim for slices no thicker than 1/4″. Smaller bits bake faster and get that soft, jammy goodness.
2. Toss with sugar, cinnamon, and lemon juice. This makes the apples taste sweet and a little tangy.

Personal Note: If you’re using apples that seem a bit tired, that’s totally fine. They’re like the underdog, turning into melt-in-your-mouth magic in this crisp.

Step 2: Make the Oatmeal Topping

1. Mix oats, flour, brown sugar, salt, and cinnamon in a medium bowl until combined.
2. Add melted butter, stirring until the mixture looks crumbly and sticks together slightly. Use your hands if you’re feeling fancy—just wash them first, please.

Why I love this step: It’s messy and smells awesome.

Step 3: Build Your Crisp

1. Pour apple mixture into a lightly buttered 8×8″ baking dish.
2. Crumble the oatmeal topping over apples, covering evenly. Don’t press down hard—loose crumbs mean more crunch.

Pro Tip: The topping is basically the best part, so feel free to sneak a little extra on there.

Step 4: Bake

1. Bake at 350ºF for about 40 minutes, until the top is golden brown and the apples are bubbly and soft.
2. Let cool for 10 minutes, so the juices thicken up—and nobody burns their mouth trying to sneak a bite.

Fun fact: The aroma will make everyone wander into the kitchen asking, “What smells so darn good?”

Tips, Tricks & Variations

Apple crisp is one of those desserts you can riff on endlessly. Here’s how to make it yours:

Pro Tips

• Use tart apples for that restaurant-level tang (think Granny Smith).
• Chop apples small if you want quicker baking and softer filling.
• Double up the topping if you’re a crunch fanatic.

Mix It Up

• Add a handful of chopped nuts (walnuts or pecans) to the oatmeal topping for extra crunch.
• Sprinkle in some dried cranberries or raisins with the apples for a twist.
• Swap part of the flour for whole wheat, if you’re feeling health-conscious (just don’t tell the kids).

Ever try warming leftovers for breakfast? IMO, it’s practically healthy—fruit, oats, what’s not to love?

Make-Ahead or Storage Tips

Because sometimes dessert needs to be prepped ahead—hello, busy weekdays.

• Make ahead: Assemble everything (except the topping) and refrigerate the apple mixture for up to 24 hours. Add the topping right before baking for max crunch.
• Store leftovers: Cover tightly and refrigerate for up to 3 days. Reheat in the oven for crispy topping—or in the microwave if patience is not your thing.
• Freeze servings: Wrap cooked crisp portions tightly and freeze for up to 2 months. Thaw before reheating.

Been there, done that, burned the casserole—and learned that a little patience goes a long way. 🙂

Serving Suggestions

Apple crisp with oatmeal topping is party-ready, potluck-perfect, or just a family treat for movie nights. Here’s how to make it a showstopper:

• Serve warm with vanilla ice cream, whipped cream, or a drizzle of caramel sauce.
• Top with a scoop of cinnamon ice cream for full autumn vibes.
• Garnish with fresh berries or mint leaves for a color pop.
