Prep your gear: Have a high-powered blender or food processor ready. If your blender struggles with frozen fruit, let the strawberries sit at room temp for 5–10 minutes.
Add the base: To the blender, add Greek yogurt, protein powder, vanilla extract, salt, and 1/3 cup milk.
Sweeten it: Add your sweetener of choice.
Start with less; you can always add more after tasting.
Blend with strawberries: Add the frozen strawberries. Pulse several times, then blend on medium-high, stopping to scrape down the sides. If the mixture is too thick, add milk a tablespoon at a time until it blends smoothly.
Taste and tweak: Adjust sweetness and add lemon juice if you want a brighter flavor.
Blend again briefly.
Choose your texture: For soft-serve, serve immediately. For scoopable ice cream, spread the mixture in a loaf pan, cover, and freeze 2–3 hours.
Scoop smart: If freezing longer, let it sit at room temp 10–15 minutes before scooping for the best texture.
