It’s officially fall, so that means it’s also officially apple season! This easy one serving apple crisp recipe really satisfies that apple craving, while indulging your sweet tooth at the same time. I had a serious hankering for something sweet, but not too gooey, and this hits the spot.
Try to use apples that are large, crisp, and juicy, but not too sweet. I am lucky enough to have access to a greenmarket with a farmer who grows 75 kinds of apples. So, I used Esopus Spitzenberg (supposedly Thomas Jefferson’s favorite apple). If you don’t have 75 kinds of apples, Granny Smith or Mutsu or similar will do just fine.
The original recipe called for 2 cups of sugar (for 12 servings), which was waaay too much. Every other recipe I saw used half that. So, I followed suit and cut it in half. It’s still sweet and delicious, without endangering your teeth.

Tools and Ingredients for Easy One Serving Apple Crisp
A mini chopper is essentially a food processor’s little cousin. This is perfect for grinding up the oatmeal in this recipe. And, it takes up a lot less space than a food processor. It’s great for chopping nuts, dicing onions, making pesto, or even grinding a small batch of meat for meatballs.
This dish is ideal for baking smaller casseroles, cakes, crisps, and crumbles. Use it for brownies, peach crumble or a mini-meatloaf. It’s perfectly content in the oven, the dishwasher, and the microwave. And, it also takes up very little space in your cupboard.
