I love berries of all kinds.

Fourth of July is only a month away. Have you started planning out your menu? Gluten and Dairy Free Mixed Berry Rhubarb Pie with its vibrant bounty of fruit is a festive and delicious way to celebrate not just Independence Day but all of the long days of the summer.
With berries at season’s peak this time of year, this dessert celebrated the gifts of nature. It doesn’t take much to allow their sweet and tart flavors to shine.
For this recipe I am using a combination of strawberries, blackberries, blueberries, and raspberries. The rhubarb adds a bright, tart note that balances and accents all of the berries.
You can either make your favorite Gluten Free pie crust recipe, or take the help of the grocery store and buy a Gluten Free pie shell. What makes this pie extra special is the lightly sweet, crunchy crumble topping featuring rolled oats, brown sugar, Dairy Free butter, and Gluten Free 1.1 flour.
I love using Bob’s Red Mill 1 to 1 Baking Flour in all of my recipes. This allows me to take recipes with regular flour and easily recreate it to be Gluten Free without having to add additional ingredients. The work is already done for you.
How to Bake Gluten and Dairy Free Mixed Berry Rhubarb Pie
With just a few simple steps and tips, this pie truly is easy as pie.
Time needed: 9 hours
Preheat your oven to 400 degrees. Place a baking sheet on the bottom rack of your oven and a second one in the center. This will keep your oven clean in the event and of the filling spills over while allowing the bottom crust to evenly brown and cook.
- Berry Easy
Add your berries, rhubarb, sugar, cornstarch, and orange zest to a bowl and mix to combine. Pour into a prepared pie shell.
- Top It Off
Make sure your Dairy Free butter is cold. Add all of the ingredients to a bowl for the crumble and mix to combine. Sprinkle all over the top of the berries. You can also opt to use pie crust to top your pie.
- Bake it Up
Bake your pie for 45 minutes. At the 25-30 minute mark check on the color and lightly tent it with foil. This will prevent the top from getting too brown.
- Cool Down
Allow your pie to cool for an hour and then refrigerate it for 8 hours to fully chill. The only question is, Dairy Free ice-cream or whipped topping?
Variations on Gluten and Dairy Free Mixed Berry Rhubarb Pie
You have options when making this pie! While it is delicious with the spiced oat crumb topping, it is equally delicious topped with pie crust. Simply make two Gluten Free Crusts for this recipe. The baking time will be about the same.
This recipe is completely gluten free and dairy free. However you can make the same recipe with both dairy butter and also your favorite pie crust.
How to Reheat Pie
There is nothing wrong with that next day cold slice of pie. However, sometimes we want to heat up our pie and give it that fresh baked form the oven warmth while slightly recrisping the crust. Plus is there anything better than that scoop of Dairy Free vanilla ice cream slightly melting into a warm slice of pie when it comes to the sweet pies?
Here are three easy ways to warm up both sweet and savory pies using the oven, air frying, and microwave.
- Oven – Preheat your oven to 225-250 degrees. Add your slices or the whole pie to a parchment paper lined baking sheet. Allow it to bake for ten minutes or until it’s warmed through. You can test the filling by touching it if it’s a slice, or using a metal skewer for a whole pie. If the metal skewer comes out warm, it’s ready.
- Air Fryer – This method is best for warming up just a couple of slices. Heat your air fryer to 350 degrees. Either wrap your slices of pie in foil or place a sheet of foil in your air fryer basket to prevent the pie filling from spilling out. Allow your pie to bake between 5-10 minutes. If it isn’t warm enough, bake it in five minute intervals until warmed through.
Microwave – Like the air fryer, this method is best for individual slices. Place the slices on a microwave safe plate and lightly cover it with a damp paper towel or microwave cover to prevent it from splattering. Working in 30 second to one-minute intervals microwave your pie slices until heated through.
Top Tip For Gluten and Dairy Free Mixed Berry Rhubarb Pie
When you are baking up your pie, check it halfway through and lightly cover it with foil. This will allow it to get golden brown and then prevent it from burning as it continues to bake.
In addition, depending on how deep your pie pan is, there is always a chance your pie might bubble over. To prevent it from spilling onto your oven, always bake your pie on a baking sheet.
