This crisp recipe feeds a crowd and it's one of my go-to party desserts. You can always cut the amounts in half and use a 9-inch pie plate to make a crisp that serves about 6.
Place the peaches into a large bowl and toss with the cornstarch and the lemon juice. Spread into the prepared baking dish.
Place the butter, yogurt, oats, flour, sugar, cinnamon, vanilla, into a medium bowl. Stir together.
Spread the topping over the peaches in the pan. Press down slightly.
Bake for 45-50 minutes or until the peaches are bubbly and soft. (If the topping starts to brown too much at any point, cover it loosely with a piece of foil and continue baking.) Let cool slightly and serve warm or at room temperature.
Notes
Store any leftovers, covered, in the fridge for up to 5 days. Serve leftovers warm or cold with yogurt, ice cream, or whipped cream.
If using fresh peaches, slice them uniformly. You do not need to peel them. Fresh peaches should be ripe but still a little firm.
If using frozen peaches, you may need to bake for the longer time duration simply since they will start very cold.
Using fresh lemon juice will add a bright flavor to the fruit, making it taste ripe and fresh even if they weren't perfectly ripe to start!
Sprinkle the peaches with a little sugar before adding the topping to make this a little sweeter.
Substitute almond flour or gluten-free flour blend for the whole wheat flour to make this gluten-free.
