Can I use frozen peaches?
Yes. You can use them straight from frozen. Just know frozen peaches vary a lot. If they are very icy or you see a lot of frost, expect the bake time to increase by about 5 to 15 minutes. You can also add an extra 1/2 to 1 tablespoon cornstarch if your peaches are especially juicy. If you want a head start, toss frozen peaches with the sugars and let them sit 5 to 10 minutes, then proceed. The cornstarch helps a ton, but giving the excess ice a minute to melt (and drain if needed) keeps things from going soupy.
What about canned peaches?
Also yes. Drain them well. If they are packed in syrup, start by reducing the sugar by about 2 tablespoons, then taste a slice and adjust if needed. If they are packed in juice, you may not need to reduce the sugar at all. I still like a little lemon juice here because it keeps the flavor bright.
Do I need to peel fresh peaches?
It is optional. Peels soften a lot during baking. If you want a smoother filling, peel them. Quick trick: score an X on the bottom, blanch in boiling water for 30 to 60 seconds, then shock in ice water. The skins usually slip right off.
What is an easy buttermilk substitute?
No buttermilk? Add 1 tablespoon lemon juice or white vinegar to a measuring cup, then fill with milk to make 1 1/4 cups. Stir and let it sit for 5 minutes, then use as directed.
Why is my cobbler runny?
Two big reasons: not enough thickener or cutting into it too soon. Let the cobbler cool at least 20 to 30 minutes so the filling can set. If your peaches are very ripe, extra juicy, or frozen and icy, do not skip the cornstarch, and consider adding a little more.
Can I make it ahead?
You can bake it earlier in the day and rewarm before serving. If you fully assemble and hold it unbaked, the topping can absorb liquid and bake up heavier. If you need to prep ahead, mix the peach filling and the dry topping ingredients separately, then combine right before baking.
What should I serve with peach cobbler?
Vanilla ice cream is the classic for a reason. Whipped cream is great too. If you want to lean Southern, try lightly sweetened whipped cream with a pinch of cinnamon.
