How to prevent runny apple pie: 7 tips for solving a soupy situation

Runny apple pie. It’s the bane of even some of the best of us bakers.

You’ve probably experienced apple pie angst yourself. You know, that moment when you hold your breath as you cut the first slice of pie and carefully lift it out to reveal … either perfectly thickened filling, the apple slices settling just a bit into the space you’ve created; or apples swimming in a sea of liquid. The former generates a sigh of relief; the latter, slumped shoulders and resigned disappointment.

Best solution to runny apple pie: Find a recipe you love and stick with it

You may already have an apple pie recipe you love, one that yields perfect results every time. If so — go ahead and read this post if you like, but we’re not about to try to get you to abandon it!

Still, if you feel timid and cautious making the same recipe over and over again, think about it: How often do you make apple pie? If you’re like most of us, probably no more than a half a dozen or so times a year: a couple during the fall harvest, one or two at Thanksgiving, maybe one at Christmas… Apple pie feels like such a fall thing, you just don’t think of making it in, say, February or June.

Given it’s an occasional treat, you needn’t worry about “same old, same old;” every apple pie you bake will be welcomed with open arms (and mouths). So don’t thrash around in online recipe-land wondering if THIS recipe will be better than THAT one. If you’ve already got the recipe of your dreams, stick with it.

Determine which apples work best for you

Your favorite recipe may not call for a specific apple variety, but you’ve probably discovered your own favorites. Some apples bake up firm, others soft. You’ll find some apples are tart and tangy, others mild and sweet. Some bakers use a single variety in their pie; others mix and match different types.

Thankfully, apple pie filling readily lends itself to thickening success — no matter which type of apple you choose.

Apples are naturally high in pectin, the intercellular “glue” that helps them keep their shape and retain their juices when baked. So you’re less likely to bake a runny apple pie than, say, a runny rhubarb pie.

Still, if you find yourself consistently producing pies that are juicier than you like, consider this: the more tart the apple the stronger its pectin. So a tart apple like Granny Smith will naturally offer more structure to pie filling than a sweeter McIntosh or Delicious.

Veteran apple pie bakers have long since chosen their favorite apples. But for those of you who haven’t, read our blog post, The very best pie apples. Spoiler alert: I like a combination of specialty-type apples, but Granny Smiths are a fine choice, and available year-round.

Runny apple pie: how to fix an existing recipe

What if the filling in your current favorite apple pie recipe is juicier (softer, more liquid-y) than you like? Or despite the reliable success of your veteran recipe, you want to try something different? Here are some tips to prevent runny apple pie.

How to prevent runny apple pie via @kingarthurflour

1. Precook the filling

I’m not advising you to cook your apples until they’re perfectly tender before spooning them into the crust; after all, they’ll continue to bake in the oven.

But by cooking apples, sugar, spices, and thickener just long enough for the apples to release their juice and the thickener to do its work — typically, 5 to 10 minutes over a burner — you reduce the risk of those same juices pooling in the bottom of the crust as your pie bakes. For further details see our post, Make-ahead apple pie filling.

2. Reduce the juice

Here’s a smart technique: put apples’ excess juice to good use by turning it into apple syrup.

Start by combining sliced apples, sugar, and a tablespoon of lemon juice. Let everything sit for an hour or so. Sugar will draw juice from the apples, which will then accumulate in the bottom of the bowl.

Drain off this juice, place it in a saucepan, and simmer until it’s reduced in volume by about half.

Once you’ve combined the apples with the remaining filling ingredients and spooned them into the crust, drizzle this syrupy juice over the apples.

The result? Less juice to collect in the bottom of the crust; concentrated apple flavor.

3. Experiment with different thickeners

If you usually use flour to thicken your apple pie and it’s not doing the job, try something different: cornstarch, tapioca, and arrowroot are other established fruit pie thickeners. For more on specific thickeners and how to use them, see our Pie Filling Thickeners Guide.

Here in the King Arthur Flour test kitchen we swear by Instant ClearJel (and its sibling, Pie Filling Enhancer). With more thickening power than flour, this modified cornstarch is similar to standard cornstarch but yields fruit filling with a softer feel, and without the gummy texture you can sometimes get from regular cornstarch.

But don’t take it from us. Here’s what one of our readers says:

“I used this for the first time in an apple pie. I was so pleased with the results. The pie holds its shape when cut and tastes great. I also think that my bottom crust stayed flakier…” Sandy — PA

ClearJel also makes fruit filling that’s freezer-safe, unlike fillings made with other thickeners, which can break down and become watery if frozen then thawed.

One cautionary note: It’s best to mix ClearJel with some of the sugar in your recipe before adding it to the apples, to prevent the ClearJel from clumping. So if you’re going to “reduce the juice” (above), save out about 1/4 cup of the sugar to add to the ClearJel.

Again, if you’re perfectly satisfied with your current recipe using flour, cornstarch, or tapioca, great! Stick with it. But if you’re not 100% sold, try Instant ClearJel.

4. Vent the top crust  

Why mar your pristine top crust by cutting holes in it? Because steam from the baking apples needs to escape, lest it collect under the crust and create (you guessed it) soupy filling.

Make sure the vents you cut are sufficiently deep and long to allow steam to escape easily. A random scattering of pinpricks with a fork isn’t going to do it!

For best results, make a series of slashes, or cut a 1″ round hole in the center of the crust. Releasing steam not only helps thicken the filling, it encourages the crust to become crisp and flaky rather than waterlogged.

5. Try a lattice or crumb top crust

Venting helps release steam in a solid-top crust. But if you’re not wed to a traditional solid-top apple pie, weave a lattice crust. Even if you place them very close together, those woven strips of pastry offer plenty of ventilation.

Never tried a lattice crust? See how it’s done: How to weave a lattice pie crust.

Even easier, make a “Dutch” apple pie: a single-crust apple pie topped not with pastry but with streusel, a crumbly mixture of butter, flour, sugar, and often oats and/or nuts.

Both a lattice crust and streusel topping are obviously much more effective than a solid-top crust (even when it’s vented) at releasing steam quickly and effectively.

6. Bake thoroughly — and then some

One of the chief reasons bakers end up with apple soup under the crust is failure to bake their pie long enough.

There’s almost no such thing as over-baking an apple pie; I’ve baked apple pies for 2 hours and longer, and they turn out just fine. But if you underbake your pie, not only will the apples potentially be crunchy and the crust wan and flabby; the combination of heat, liquid, and thickener won’t have sufficient time to work.

Juice bubbling out the edges of the pie is actually a good sign: it shows the filling is hot enough to thicken.

When apple pie bakes, the apples exude juice. At some point that juice starts to boil, which releases excess moisture in the form of steam. In addition, the starch in the thickener absorbs some of the water in the juice, making the remaining juice highly flavorful and dense enough to hold the apples in place.

For best results, bake your apple pie for at least 10 more minutes after you see juice actively bubbling out the vents (or edges) in the top crust. Note: Baking your pie on a parchment-lined baking sheet (to catch any filling overflow) helps you avoid a smoking mess on the oven floor.

7. Let the pie cool completely — preferably overnight

Even a perfectly thickened pie may show signs of excess juiciness when cut into directly out of the oven. As the pie cools, its filling will solidify. It takes time for pie to cool thoroughly and its filling to thicken completely, so control your appetite and let it rest for several hours.

At left, pie served hot from the oven; notice how it can’t hold its shape on the plate. At right, a slice of that same pie cut the next day.

Better yet, let the pie rest all day (or overnight) at room temperature; this will further solidify the filling, as well as melding its flavors.

If you want to serve the pie hot, reheat individual slices very briefly in the microwave — just enough to warm the filling but not enough to toughen the crust.

How to prevent runny apple pie: your takeaways

  1. Drain apples of much of their juice, then simmer the juice until thick before adding it back to the filling.
  2. Partially pre-cook the filling to evaporate its excess juice.
  3. Experiment with different thickeners beyond flour.
  4. Vent the pie’s top crust so steam from juice can escape.
  5. For even better evaporation, try a lattice crust or crumb crust.
  6. Bake pie thoroughly; let it remain in the oven for at least 10 minutes after its juices begin to boil.
  7. Cool pie all day (or overnight) before cutting.

    My husbands grandma baked the best apple pies ever. Always with Northern Spy apples. Some years I have to search high and low for them. They do need a bit of sugar but hold up well in the pie. I am ordering some pie filling enhancer. My husband can never wait for the next day to taste the pie.

    My favorite solution is to add dried fruit to the filling, which absorbs the extra liquid from the apples. =) I love raisins in apple pie, but dried cranberries would also work nicely. I always top with streusel, too, rather than a top crust.

    So happy I just disovered your web site.The one thing my Alsatian mother taught me to make was apple pie. Granma and Mom and I went to the farmers’ market in San Antonio to buy a bushel of Jonathon apples in the fall.They are crisp and tart, best for eating and great for pies.We tried different amounts of sugar, not more than 2/3 c was best. We never cooked apples ahead, used cinnamon and just tad of nutmeg if any, vented with slits in lid, used flour to thicken,though I can see that cornstarch would work better because it dissolves quicker with liquids as in Chinese stir frying, and I took great pride in learning to make a latice top if we enough time( Mom worked 9–to –5). Brings back great memories sitting on that old stool with the folding steps by the rolling cabinet next to the combination gas stove with the wood burning side.

    From my perspective, you could have saved yourself a long article and just told us to use your pie filling enhancer. ;-D I tried for YEARS (I’m an old person ;-D ) to make a decent apple pie because my husband loves them. They were all just ok, and usually too runny. I tried flour, cornstarch, mixing apple types and using half for flavor and half for structure, cooking the filling first, using canned filling (the horror!) … you name it. Then, one day, I send off for your pie filling enhancer and the problem was solved. I feel like I’m cheating somehow when I use it, but after this many years, I don’t care LOL. Oh, and I also tried Braemar apples with that first PFE pie and they were wonderful. It’s been hit-and-miss on the apples (they’re sometimes hard to find), but I can always get your pie filling enhancer!

    Very interesting article, PJ. I have a tried-and-true recipe for apple pie that has never come out runny. However, some of the suggestions in the article and from contributors peak my interest. I’m going to have to try them all, just for fun and have family and friends “judge” which they find the best.

    My favorite combination of apples is Honeycrisp and good old Cortland. I add freshly grated nutmeg to the cinnamon, but just a little. Also, I go easy on the sugar, as others have suggested. Let the delicious apple flavor shine through!

      Judith, I’m gradually becoming more of a Cortland fan, for their flavor; it seems like, with the Honeycrisp, you’d have a good combination of textures, too. And an apple pie bakeoff? YES!! PJH@KAF

      Cortland is my absolute favorite for pies! My biggest issue is that when the pie is cut (it’s cooled, and the filling isn’t runny), it doesn’t stay together in anything that remotely resembles a pie wedge! I want a pie wedge when I’m serving it.

    3. The Baker's Hotline

      Jodi, it sounds like some of the tips in this post could be helpful for you! To some degree, apple pie slices will always have a little runaway filling, but extra thickener and good, firm apples can help. Also, make sure your knife is regularly honed and sharpened. A dull knife can definitely cause your crust to smoosh into your filling a bit (that’s the technical term, we promise), which in turn gives your filling nowhere to run but out onto the plate. Happy baking! Kat@KAF

    Some time ago I read a tip by a KAF member who said “let the apples speak for themselves”. Since then I use almost no sugar but do add spices and the pies taste Delicious.

      Sweet apples need very little sugar, Barbra, it’s true; as another commenter here said, it’s always good to taste the apples before deciding how much sugar to add. I do like to add some; I feel it helps with the filling texture, but kudos to you for cutting way back on the sugar, flavoring with spices, and “letting the apples speak for themselves.” PJH@KAF
