Chill your base: Place the yogurt in the fridge until very cold.
Cold ingredients freeze faster and create a better texture.
Prep the fruit: Peel and slice the bananas. If your berries are large, roughly chop them. Keep fruit frozen if you want a thicker, quicker churn.
Blend smooth: In a blender, combine Greek yogurt, bananas, berries, vanilla, lemon juice, and a pinch of salt.
Blend until creamy with no chunks. Taste and adjust lemon or vanilla. If using a no-calorie sweetener, add a small amount now and blend again.
Chill the mixture: Pour into a bowl and refrigerate 1–2 hours.
This step helps prevent iciness and speeds up churning.
Churn (ice cream maker): Add the cold mixture to your machine and churn according to the manufacturer’s instructions, usually 20–25 minutes, until thick and soft-serve-like.
Freeze to scoopable: Transfer to a lidded, shallow container. Press a piece of parchment directly onto the surface to limit ice crystals. Freeze 2–4 hours, until scoopable.
No-machine method: Pour the mixture into a shallow, freezer-safe dish.
Freeze for 45 minutes, then whisk vigorously or beat with a hand mixer to break up ice crystals. Repeat every 30 minutes for 2–3 hours, then freeze until firm.
Serve: Let the frozen yogurt sit at room temperature 5–10 minutes before scooping for the best texture.
