Ingredients

Why this recipe works

Slow cooking allows the cranberries to pop and release their natural pectin, creating a thick, jammy sauce without any added thickeners.

The low, steady heat also softens the apples while keeping them distinct, so every bite has a mix of tender fruit and bright, tart bursts. The maple syrup and orange zest infuse the fruit as it cooks, deepening the flavor without becoming cloying.

The streusel, made with oats, walnuts, and cold butter, stays crisp on top because it is not stirred into the fruit.

The slow cooker's moist heat gently toasts the topping while the fruit bubbles beneath, producing a texture that mimics a baked crumble. This method also keeps the kitchen cool and the oven free for other dishes—a win for any holiday cook.

Notes and substitutions

Choose firm, sweet apples like Honeycrisp or Fuji that hold their shape during slow cooking. Tart Granny Smiths can be used, but you may want to add a touch more maple syrup. Fresh cranberries are ideal, but frozen (unthawed) work well—just add 10 minutes to the cooking time. Do not use dried cranberries, as they will not provide the same juicy pop.

The streusel is the heart of this crumble. Use old-fashioned rolled oats, not instant, for the best texture. Walnuts can be swapped for pecans or hazelnuts. Keep the butter cold until you cut it into the dry ingredients—this ensures a crumbly, not greasy, topping. If the topping begins to brown too quickly, cover it loosely with foil.

• Honeycrisp apples: Use any firm, sweet apple like Fuji, Gala, or Braeburn. Tart Granny Smith can be used, but add an extra tablespoon of maple syrup.
• Fresh cranberries: Frozen cranberries work without thawing. Add 10 minutes to the cooking time.
• Walnuts: Pecans or hazelnuts can replace walnuts. For a nut-free version, use additional oats.
• All-purpose flour: Use a 1-to-1 gluten-free flour blend for a gluten-free streusel. Ensure oats are certified gluten-free.
