1. Preheat your oven to 350°F (175°C) and grease an 8×8 or 9×9 baking dish well. Don’t skip greasing or you’ll be scrubbing caramelized berry juice forever.
2. In a large bowl, combine the sliced strawberries, granulated sugar, and cornstarch. Toss gently but thoroughly until every strawberry slice is evenly coated. Transfer the mixture to your prepared baking dish and spread evenly. Let it sit for 5 minutes while you make the topping.
3. In a separate bowl, combine the old-fashioned oats, flour, packed brown sugar, cinnamon, and salt. Mix until everything is evenly distributed and no brown sugar lumps remain.
4. Pour the melted butter over the oat mixture and stir with a fork until everything comes together in a crumbly, clumpy texture with some big clusters and some smaller bits. This texture variation is what makes crumble so satisfying.
5. Sprinkle the oat topping evenly over the strawberry filling, covering the entire surface. Pat it down very gently with your hands to help it form a cohesive topping that won’t slide off.
6. Bake in the preheated oven for 35-40 minutes until the topping is deeply golden brown and you can see the strawberry filling bubbling enthusiastically around the edges. That bubbling means the filling has thickened properly.
7. Remove from the oven and let cool for at least 10 minutes before serving—the filling needs time to set slightly. Serve warm with a generous scoop of vanilla ice cream and watch it melt into all those gorgeous jammy layers.

Notes:

• Seriously, use old-fashioned oats or your topping will be mushy instead of chewy
• Don’t skip the cornstarch in the filling or it will be watery and ruin the topping
• The filling should be visibly bubbling around the edges before you pull it out
• Let it cool at least 10 minutes before serving so the filling thickens properly
• Deeply golden brown topping means maximum flavor—don’t pull it out too early

Storage Tips:

• Keep covered at room temperature for up to 2 days or refrigerate for up to 4 days
• Reheat individual portions in the microwave for 60 seconds or the whole dish at 300°F for 15 minutes

Mix It Up (Recipe Variations):
