Strawberry blueberry Salad is a festive and light summer side for the 4th of July and other summer celebrations! It’s a sweet mixed berry salad with bursts of fresh fruit, pockets of mini marshmallows, and a fantastic citrus poppy seed dressing that ties it all together.

Easy fruit salads like this one work perfectly for May celebrations like Mother’s Day and Memorial Day. And, because this recipe has no mayo or dairy products that can spoil in the heat, it’s also perfect in the hot months of summer! 

The red white and blue colors make it a festive side dish for your July 4th cookouts, pool parties, and picnics.

Why We Love Strawberry Blueberry Salad

1. It’s a tasty way to enjoy fresh summer fruit. And if your favorite berries aren’t in season, it’s just as easy to make with frozen fruit!
2. Easy to make ahead. As long as you leave the dressing off, you can prep the berries up to 4 days ahead of time.
3. It doesn’t weigh you down.  We love picnic sides like calico beans and potato salad, but they’re a bit heavy. It’s nice to have a lighter option for the really hot days. And the dressing tastes great with almost any salad you can think of!

Ingredient Notes and Substitutions 

• Strawberries and Blueberries – Any substitutions that keep this a red white and blue salad are great! Raspberries, blackberries, even cherries — just consider how easy they are to slice, and if they might break up the texture of the salad overall. 

For the Fruit Salad Dressing

• Citrus fruit – We use the zest and juice of an orange and a lime. Oranges are easy to find almost all year long, but the lime crops have had rough year weather-wise. If you have trouble finding good limes, lemons will do just fine.
• Honey or Maple Syrup – For a lighter taste that highlights the fruitiness of the strawberry blueberry salad, go with honey. But if you enjoy the vanilla-like taste of maple with your fruit, use maple syrup as your dressing base. Or use a mix of both!
• Poppy Seeds – These seeds don’t just add texture, they have a subtle nutty and pleasantly sweet flavor, too. 

Making Mixed Berry Salad With Frozen Fruit

We actually love working with frozen fruit. It’s usually harvested when it’s perfectly ripe, which actually means that frozen fruit can sometimes have more nutritional value than fresh.

Frozen fruit is also easier to slice! The harder flesh won’t squish and leak juice while you’re cutting into it, and you can get slices that are both thinner and more uniform.

Just be sure to give the fruit a bit of time to thaw before you serve the strawberry blueberry salad. An hour or so in the fridge is usually plenty of time after the fruit has been sliced! 

Sometimes you can even find frozen strawberries that have already been sliced to save even more time!

Strawberry Blueberry Salad Recipe Tips

1. Give the berries a good rinse to brighten their color.

Of course, you should avoid using any fruit that has visible signs of mold or dark black spots. However, if your strawberries are just a little mushy looking, a quick rinse in cool water can spring them back to life!

1. Don’t toss the fruit salad until just before serving.

As any mixed berry salad lover knows, the longer fruits sit together, the more likely the flavors are to meld together. This means, eventually the fruits will lose their individual flavor. 
It’s ideal to wait until the day of serving to combine the fruits for the best possible flavor and texture.

2. Use freshly zested and juiced limes and oranges.

Concentrated juice (lime, lemon, and orange alike) has a very artificial, abrasive flavor. The dressing will maintain a much fresher, sweeter flavor when you use freshly squeezed juice.

As for the zest, be sure to not zest down to the pith (that’s the white, spongy part below the peel). The pith is bitter and doesn’t taste good at all.

3. You can make strawberry blueberry salad with or without marshmallows.

The dish is just as delicious without them! Alternatively, a small bowl of colored marshmallows or even marshmallow fluff can be served on the side for friends and family to add on their own.

If you’d like to serve a sweet dessert salad, try our red white and blue cheesecake salad! It’s definitely more dessert-like than this 4th of July salad. Kids love the sweet cream cheese and pudding mix base!

Mixed Berry Salad FAQ

What other fruits go well with strawberries and blueberries?

Blackberries and raspberries would be our first two recommendations. For more of a classic easy fruit salad, sliced oranges, apples, grapes, and bananas are great options.

If you’re willing to go outside the fruit category, spinach and other leafy greens are a great addition to build a more substantial salad!

Storing and Serving

The mixed berry salad will stay fresh for up to 5 days in the fridge. However, the dressing will make the berries get soggy pretty quickly. If you anticipate leftovers, store the dressing and fruit separately. The dressing will keep a little longer than the fruit.
