Add the Greek yogurt, blueberries, honey or maple syrup, vanilla extract, salt, and any optional ingredients like chia seeds or cinnamon into a blender or food processor. Using full-fat Greek yogurt will give the frozen yogurt a richer and creamier texture, while frozen blueberries can help create a naturally thicker consistency. If your blueberries are frozen solid, let them sit at room temperature for a few minutes first so they blend more easily.

Blend the mixture on high speed until it becomes completely smooth, creamy, and evenly colored. The blueberries should fully break down into the yogurt so there are no large fruit pieces remaining. This step is important for achieving a silky frozen yogurt texture instead of an icy or chunky consistency. If the mixture looks too thick for your blender, add a very small splash of milk to help it blend smoothly.

Pause the blender once or twice and use a spatula to scrape down the sides of the blender or food processor. Blueberries and yogurt can sometimes stick along the edges, so scraping everything back into the center ensures the flavor and color distribute evenly throughout the mixture. Continue blending until the texture looks smooth and creamy with no streaks remaining.

Taste the blueberry yogurt mixture before freezing and adjust the flavor as needed. If you prefer a sweeter frozen yogurt, add a little more honey or maple syrup and blend briefly again. For brighter berry flavor, you can add a small squeeze of fresh lemon juice or a little extra vanilla extract. Keep in mind that frozen desserts taste slightly less sweet once fully frozen, so the mixture should taste just slightly sweeter than you want the final result to be.

Pour the blended mixture into a shallow freezer-safe container and use a spatula to spread it into an even layer. A shallow container helps the frozen yogurt freeze more evenly and creates a smoother texture. For extra protection against ice crystals, you can press a piece of parchment paper or plastic wrap gently against the surface before covering the container.

Cover the container tightly and place it in the freezer for about 2–3 hours, or until the frozen yogurt becomes firm but still scoopable. If you prefer a softer frozen yogurt texture, check it closer to the 2-hour mark. Avoid freezing it for too long without checking, as homemade frozen yogurt can become very hard once fully frozen.

If the frozen yogurt becomes too firm after longer freezing, remove the container from the freezer and let it sit at room temperature for about 5–10 minutes before scooping. This allows the texture to soften slightly, making it easier to scoop while also improving the creaminess and flavor.

Scoop the frozen yogurt into serving bowls or cones and add your favorite toppings if desired. Fresh blueberries add extra freshness and color, while chopped walnuts provide crunch and healthy fats. Chia seeds, mint leaves, shredded coconut, or a light sprinkle of cinnamon also work beautifully for extra texture and flavor. Serve immediately while cold, creamy, and refreshing.
