Preheat your oven to 350°F (180°C) and grease the baking dish of your choice. A 8x10, 9x9, or 10 inch round pie dish all work great.
In a large bowl, toss the chopped strawberries with the sugar, 1½ tbsp flour, lemon zest, and vanilla until they are evenly coated. Transfer the berries to your baking dish and arrange in an even layer on the bottom.
In a separate bowl, mix the flour, rolled oats, brown sugar, granulated sugar, cinnamon, and salt together until well combined. Then, pour the melted butter over the mixture and use a spatula to fold until a dough comes together.
Sprinkle the crisp on top of the strawberries.
Bake for 35-40 minutes, or until the strawberries are bubbling and crisp is a light brown. Let cool for 10 minutes. Then, serve warm with vanilla ice cream and fresh strawberries.
