Strawberry Rhubarb Custard – A Sweet-Tart Classic with Creamy Comfort

Strawberry rhubarb custard is pure comfort in every bite. With sweet strawberries, tangy rhubarb, and silky custard, it’s a timeless spring and summer treat that never goes out of style.

At Recipes of Kitchen, The Gluten-Free Sweet Kitchen, I believe that delicious desserts should be accessible to everyone. When I had to give up gluten for my health, I refused to give up on flavor, so I set out to reimagine classic recipes into something both safe and satisfying. This custard recipe is one of my go-to treats that proves gluten-free baking can be just as satisfying.

Key Ingredients That Make It Special

Strawberry rhubarb custard stands out because it blends simple ingredients into something rich, fruity, and satisfying. Each element plays a key role in both flavor and texture.

Core Ingredients Explained Strawberry Rhubarb Custard

Ingredient	Role in the Recipe
Strawberries	Add natural sweetness, bright color, and juicy texture
Rhubarb	Provides tartness and a soft bite that balances the sweet custard
Eggs	Thicken the custard and create a rich, smooth texture
Milk or Cream	Adds creaminess to the custard; use heavy cream for extra richness
Sugar	Sweetens both the custard and the fruit
Vanilla Extract	Enhances the flavor of the custard and adds warmth
Salt	Balances sweetness and sharpens flavors

Ingredient Tips

• Use fresh strawberries for the best color and flavor. If using frozen, thaw and drain well.
• Chop rhubarb into small, even pieces so it cooks evenly in the custard.
• Full-fat dairy results in a creamier custard, but you can use half-and-half or plant-based milk for a lighter version.
• Adjust sugar depending on how tart your rhubarb is. Some varieties are more sour than others.

Flavor Boosters (Optional but Delicious)

• A Pinch of Cinnamon or Nutmeg
• Adds cozy warmth and depth to both the custard and the fruit mixture, perfect for enhancing those classic flavors.
• A Splash of Lemon Juice
• Brightens up the fruit mixture, balancing the sweetness and highlighting the natural tartness of the rhubarb.
• Cornstarch or flour can be used for added thickness in bar or pie variations

Choosing the Right Rhubarb and Strawberries

The flavor of strawberry rhubarb custard starts with the quality of your fruit. Selecting the right ingredients ensures a sweet-tart balance and the perfect texture after baking.

Choosing Strawberries

• Use fresh, ripe strawberries when in season for the best flavor and color
• Look for berries that are:
  • Bright red all over
  • Fragrant
  • Firm, not mushy
• Frozen strawberries are a backup option
  • Thaw completely
  • Drain excess liquid to prevent watery custard

Choosing Rhubarb

• Fresh rhubarb stalks should be:
  • Bright pink or red
  • Firm and crisp
  • Free from blemishes or limp spots
• Avoid rhubarb leaves (they’re toxic)
• Field-grown rhubarb tends to be more tart than hothouse rhubarb
• Frozen rhubarb is convenient
  • Chop before freezing or buy pre-chopped
  • No need to thaw fully before baking, but measure frozen for accuracy

Fresh vs Frozen Comparison

Flavor	Bright, clean taste	Slightly muted due to freezing
Texture	Firmer, better for pies or bars	Softer, better for custard cups
Convenience	Requires prep (washing, hulling)	Prepped and ready

How to Make the Perfect Custard Base

The custard is what ties the entire strawberry rhubarb custard together. It’s rich, creamy, and contrasts beautifully with the sweet-tart fruit. Getting it right is key to a successful dessert.

What Is Custard?

• A creamy mixture of eggs, milk (or cream), and sugar
• Thickens gently when heated
• Can be poured over fruit or layered into a pie or tart

Basic Custard Ratio

Ingredient	Standard Amount (for 4–6 servings)
Eggs	3 large
Milk/Cream	1 ½ to 2 cups
Sugar	⅓ to ½ cup
Vanilla Extract	1 to 2 teaspoons
Salt (optional)	A pinch

Steps to Make a Smooth Custard

1. Whisk eggs and sugar together until well combined
2. Heat milk or cream until just warm (not boiling)
3. Temper the eggs by slowly pouring in the warm milk while whisking nonstop; this keeps the eggs from scrambling.
4. Add vanilla and salt
5. Strain the mixture through a fine mesh sieve (optional but recommended) for extra smooth texture

Tips for Custard Success

• Use room temperature eggs to prevent curdling
• Don’t let the milk boil; keep it warm to avoid scrambling the eggs
• Always whisk while adding warm milk to temper gently
• Pour custard slowly over fruit to ensure even cooking

Common Custard Problems and Fixes

Problem	Cause	Solution
Curdled custard	Milk was too hot or overbaked	Temper gently and use a water bath if needed
Watery custard	Not cooked long enough	Bake until edges are set and center jiggles
Grainy texture	Eggs cooked too fast	Strain mixture before baking
Overly eggy taste	Too many eggs or under-sweetened	Adjust ratio of sugar to eggs

Baking and Assembly Techniques

Getting the texture and flavor just right in strawberry rhubarb custard depends on smart baking and assembly. Whether you’re making a pie, custard cups, or bars, these steps help you avoid common mistakes.

How to Assemble Your Custard

1. Prepare fruit first
   • Toss strawberries and rhubarb with a small amount of sugar
   • Let sit for 15–20 minutes to release juices
   • Drain excess liquid to avoid watery custard
2. Layer or mix
   • For pies and bars: layer fruit on the crust, then pour custard over
   • For ramekins or crustless versions: gently fold fruit into the custard mixture
3. Pre-bake crusts (optional)
   • For custard bars or pies, blind-bake crust for 10–12 minutes at 375°F
   • Prevents sogginess from fruit juices

Baking Temperature and Timing

Recipe Type	Temp	Time	Notes
Custard Pie	350°F	45–55 minutes	Center should be just set
Baked Custard Cups	325°F	30–40 minutes	Bake in a water bath for gentle heat
Custard Bars	350°F	35–40 minutes	Cool fully before cutting

Doneness Test

• Edges set, center slightly jiggly when gently shaken
• Toothpick or knife inserted in center should come out clean or with a moist crumb
• Do not overbake or the custard may split or curdle

Serving Suggestions and Pairings

Once baked, strawberry rhubarb custard can be dressed up or enjoyed simply on its own. Here are some ideas to make your dessert shine.

Best Ways to Serve
