It’s not summer until someone busts out the strawberries and rhubarb…
To make something… ANYTHING!
Ice cream and pies, crumbles and crisps, cobblers and more, ohhhhh yes! Oh, and don’t forget about the rhubarb juice! Have you seen my 2-ingredient recipe for Instant Pot Rhubarb Juice?!
And now? A super easy Instant Pot Strawberry Rhubarb Custard!
If you can get your hands on some rhubarb this season, DO IT!
Strawberries + Rhubarb = Low-Carb Summer Essentials!
If summer desserts have you on carb overload, look to blood sugar-friendly, low-glycemic strawberries and rhubarb. (Plus, this custard is sweetened with only stevia!)
Botanically speaking, rhubarb is a vegetable. Yet, it is often thought of as a fruit because it’s primarily used in sweet dishes.
Rhubarb has just 3 grams net carbs per cup — making it extremely low-carb and also keto-friendly.
Strawberries are another keto/low-carb fruit with just 6 grams of net carbs per cup.
The remaining ingredients in this easy paleo Instant Pot custard — full fat coconut milk, eggs, stevia — are also keto-friendly.
A Recipe That Multi-tasks: Strawberry Rhubarb Custard For Breakfast (or dessert or a snack!)
There’s absolutely no reason you shouldn’t have this yummy strawberry-rhubarb custard for breakfast because…
It’s got plenty of protein, too!
I’ve added grass-fed collagen and gelatin to this sugar-free Instant Pot custard to amp up the protein and give you a healthy start to your day. (Learn the difference between collagen and gelatin here!) The collagen isn’t an absolute necessity in this recipe, but it does add thickness (and, about 30 extra grams of protein).
The gelatin, however, is necessary because it’s what turns this into a silky, creamy custard!
If you like, make this custard in individual jars for an easy grab-and-go breakfast or snack.
And, although rhubarb isn’t typically in season during the school year, these custards would make a great addition to a school lunch, too.
Pssst! Love the Weck jars I use in these photos? You can find them right here!
I love a recipe that multi-tasks, don’t you? 😉
How To Make Stevia-Sweetened Instant Pot Strawberry Rhubarb Custard
It’s really as easy as throw everything into your blender, blend, and pressure cook!
You add all the ingredients except gelatin to your blender. I have a high-powered BlendTec that works like a boss for making pudding and custard bases super smooth.
Once everything is blended, add the gelatin last.
Then, it’s time to cook. You have a couple of options:
- Pour the custard base into a 1.5-quart glass bowl (like this) or casserole dish with a lid (like this). If your bowl doesn’t have a glass lid, cover with parchment first, then foil to prevent water from coming into the custard. Place the dish on the metal trivet, and then pressure cook.
- Or, divide the custard base into 8-ounce jars (like these or these). Put lids on the jars. Place the jars on the metal trivet, then pressure cook.
If serving your Instant Pot Strawberry Rhubarb Custard family-style, the bowl or casserole dish is the way to go.
However, if you’re liking the idea of individual servings, especially for on-the-go snacking or a quick breakfast, go with the jars.
The ingredients, prep, cooking time… everything is the same either way!
Now, let’s make some Paleo Instant Pot Strawberry Rhubarb Custard!

Add the gelatin and blend again.
- Pour the mixture into a 1.5-quart glass dish and cover with parchment then foil or a glass lid. Or, divide the mixture evenly between 5 8-ounce jars and secure a lid on each jar.
- Prepare your Instant Pot by placing the stainless steel trivet in the bottom of the pot along with 1 cup of water.
- Place the jars filled with custard mix on the trivet.
- Put the lid on your Instant Pot, seal the vent, and press the "Manual" button. Adjust the time to 5 minutes on high pressure.
- When it beeps, immediately release the pressure.
- Using an oven mitt or pair of tongs, carefully remove the hot jars from the Instant Pot and set them aside to cool to room temperature.
- When cooled to room temp, transfer the jars to the fridge to finish setting.
- The mixture will likely separate as it cools. This is normal. Simply give each jar a shake to re-emulsify as the custard cools.
- When the custard is totally set and cold, it's ready to enjoy!

This recipe is delicious. Breakfast just because I could
Heck yes! Dessert for breakfast because you can! Thanks for commenting and leaving a review!
This recipe is delicious! Will make again- breakfast yum in a jar. Easy peasy
I had trouble with this. When I first blended it all up it was nice and smooth. Then after I added more stevia and blended again it began to separate. Not sure what I did wrong. I continued with the recipe anyway. It tasted great, just not smooth like custard should be. Kind of chunky. Any ideas? I would love to try again. Maybe with heavy cream?
It’s strange that it separated after you added the stevia… Did you blend it in a blender? Did you shake it after you put it in the fridge a few times?
Yes, I have a Vitamix. I used a 1.5 quart dish, but after I blended it the second time it looked like little pieces of coconut from the milk floating around. One thing I did not do was let the eggs come to room temperature so maybe that was it? I will try it again. It still tasted great though! l’m still eating it:)
The little bits of coconut is normal. Mine does the same thing, but as long as I shake it while it’s cooling, it doesn’t get chunky for sure. Glad you’re enjoying it anyway!
Lindsay – I love this custard. I’m making it for the second time and adding blueberries. There is a mistake in the recipe that may throw some folks. “Finally, add the collagen and blend again.” I believe that’s the step where you “add the gelatin” because the collagen has already been combined. Great job with your blog. Sending you gratitude for the recipes.
Wonderful! And oops! I’ll get that fixed! 🙂
There’s still an error in the recipe so glad I saw this comment and modification with blueberries.
Hi, could you point out the error in the recipe, please?
