Ingredients You Need:

Keto bread: thankfully, with the rise in popularity of the keto diet, there are lots of store-bought options for keto- bread. However, you could also make your own as well if you have a recipe that you love.

Greek yogurt: opt for plain Greek yogurt and skip any excess sugar. This is what helps give a thick taste to the custard and a protein kick to the recipe.

Egg: any eggs you have on hand work just fine. Note that you only need the yolk though so make sure to separate it first.

Sugar-free honey: the custard is minimally but deliciously sweetened with keto-friendly honey. Other liquid sweeteners may work but honey gives the best consistency.

Vanilla extract: with so few ingredients, having a higher quality vanilla will make a difference to the taste of the custard toast.

Strawberries: any fresh berries you have on hand are fine. Switch up the flavor easily enough by switching up the fruit you use.

How To Make It:

  1. In a small bowl, combine the Greek yogurt, egg, honey, and vanilla. Whisk until it’s smooth.
  2. Place the bread slices into a greased air fryer pan and press down in the center of each to form a cavity.
  3. Pour the custard mixture into the cavity in each bread.
  4. Top the toast with slices of strawberries.
  5. Place in a preheated air fryer for 10 minutes or until the bread is toasted.

Expert Tips To Make It:

When you’re pressing the bread down for the indentation, press lightly. You don’t want any holes in your bread for the custard to drip through.

Part of this will also depend on the thickness and brand of keto-bread so be gentle. The softer the bread the better though.

Mix the custard really well, the last thing you want is chunks of egg throughout it.

Air fry the toast until the bread is getting crispy, and slightly caramelized and the custard is cooked through all the way. Keep an eye on the last minute or so and adjust the cooking time as needed.

Topping The Air Fryer Custard Toast:

Though there are strawberries cooked right onto the toast, you can adjust and vary this keto recipe each time you make it by adding a bit more.

First, you can easily switch up the berries used. Strawberries are great but blackberries are a delicious keto-approved fruit as well.

Top the custard toast with fresh berries along with the cooked ones for a delicious pop of flavor.

Once cooked, drizzle the toast with a keto chocolate syrup to make it into an easy dessert.

You can also drizzle a slightly warmed nut butter over the custard toast to make it more rich.

Frequently Asked Questions About Keto Air Fryer Custard Toast:

Q. Can you make custard toast in the oven?

A. Yes, if you don’t have an air fryer, you can still make this popular TikTok recipe. Prep the toast as it’s listed but instead of placing it in the air fryer, bake it in the oven at 350F. It will take a bit longer (12-15 minutes) so make sure to keep an eye on it and make sure it doesn’t burn.

Q. Why is my air fryer not browning toast?

A. The secret to making toast crispy and brown in the air fryer is to make sure that you’re placing it into a greased pan. This is what will create the golden brown look that you’d expect with toast.

Q. Can you reheat keto custard toast?

A. Keto custard toast is best eaten fresh as that’s when the custard will be the richest. However, if you have leftovers, let them cool before storing them in an airtight container in the fridge for up to 2 days. Reheat the custard toast in the air fryer.
