Apples for Isaac is a warm, comforting dessert of tender apples baked in a buttery cinnamon sauce, topped with a crisp oat streusel. It works because it uses everyday ingredients and simple techniques to turn firm apples into a soft, caramelized filling that pairs beautifully with the crunchy topping. This dish is perfect for a cozy weeknight treat or a simple fall gathering.
Ingredients
- 6 medium firm apples (such as Honeycrisp, Fuji, or Granny Smith), peeled, cored, and sliced into 1/4-inch (6 mm) thick wedges
- 1/4 cup (50 g) granulated sugar
- 2 tablespoons (28 g) unsalted butter, melted
- 1 tablespoon (15 ml) lemon juice
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/8 teaspoon salt
- For the streusel topping:
- 1/2 cup (60 g) all-purpose flour
- 1/2 cup (40 g) old-fashioned rolled oats
- 1/2 cup (100 g) packed light brown sugar
- 1/2 teaspoon ground cinnamon
- 1/4 cup (56 g) cold unsalted butter, cut into small pieces
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9-inch (23 cm) square baking dish or a 10-inch (25 cm) round pie dish.
- In a large bowl, combine the sliced apples, granulated sugar, melted butter, lemon juice, cinnamon, nutmeg, and salt. Toss well to coat every apple slice evenly.
- Transfer the apple mixture to the prepared baking dish and spread it into an even layer.
- In a separate medium bowl, make the streusel. Whisk together the flour, oats, brown sugar, and cinnamon. Add the cold butter pieces and use a pastry blender or your fingertips to work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized butter chunks.
- Sprinkle the streusel evenly over the apples.
- Bake for 40–45 minutes, until the apples are tender when pierced with a fork and the topping is golden brown. If the topping browns too quickly, loosely cover the dish with foil for the last 10 minutes.
- Let the dish rest for 5 minutes before serving. Serve warm.
Tips
- Apple choice: Use firm, tart-sweet apples like Honeycrisp, Fuji, or Granny Smith. Softer apples like McIntosh may turn mushy during baking.
- Butter temperature: For the streusel, the butter must be cold. If it warms up, the topping will become greasy instead of crumbly. You can chill the flour mixture and butter in the freezer for 10 minutes before mixing if your kitchen is warm.
- Even slices: Slice the apples uniformly so they cook at the same rate. Aim for about 1/4-inch (6 mm) thick wedges.
- Make ahead: You can assemble the entire dish (without baking) up to 24 hours ahead. Cover and refrigerate, then bake as directed, adding 5–10 minutes to the baking time.
Serving Suggestions
Serve this warm, straight from the oven, with a scoop of vanilla ice cream or a dollop of lightly sweetened whipped cream. A drizzle of caramel sauce also pairs beautifully. For a breakfast twist, serve leftovers with a spoonful of Greek yogurt.
Variations
- Add dried fruit: Toss 1/3 cup (50 g) of raisins or dried cranberries with the apples before baking.
- Add nuts: Mix 1/2 cup (60 g) of chopped pecans or walnuts into the streusel topping.
- Spice it up: Replace the nutmeg with 1/4 teaspoon of ground ginger or cardamom for a different flavor profile.
- Gluten-free: Use a gluten-free all-purpose flour blend in the streusel instead of regular flour.
- Reduce sugar: If your apples are very sweet, reduce the granulated sugar to 3 tablespoons (38 g).
Storage and Reheating
Store any leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, place a portion in a microwave-safe dish and heat on medium power in 30-second intervals until warmed through, or reheat in a 350°F (175°C) oven for 10–15 minutes. The streusel will soften upon storage, but it will still taste delicious. You can also freeze the baked dish for up to 3 months; thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
Can I use pre-sliced apples? Yes, you can use store-bought pre-sliced apples, but they are often treated to prevent browning and may have a slightly different texture. If using them, reduce the lemon juice to 1 teaspoon, as they may already be acidic.
Why is my streusel not crumbly? This usually happens if the butter is too warm or if you overmix. Make sure the butter is cold and stop mixing as soon as the mixture looks like coarse crumbs. If it becomes a paste, chill it for 10 minutes before sprinkling.
Can I make this in a cast-iron skillet? Absolutely. Use a 10-inch (25 cm) cast-iron skillet. You can even start the apples on the stovetop for a few minutes to soften them slightly, then add the streusel and bake.
Do I need to peel the apples? Peeling is recommended for a smooth, tender texture. If you leave the peel on, it will become chewy and may separate from the apple during baking. If you prefer a more rustic texture, you can leave it on, but slice the apples thinner.
Can I use quick oats instead of old-fashioned oats? Yes, but quick oats will produce a finer, less textured streusel. Old-fashioned oats give a heartier crunch, which is why they are preferred.
Is this safe for children? Yes, this is a fully cooked dessert. The apples are baked until tender, and the dish is safe for all ages. Just ensure it has cooled to a safe temperature before serving to young children.
