Step 1: Prep & Preheat
Preheat oven to 400°F (200°C).
Line a baking sheet with parchment paper.
Step 2: Mix Dry Ingredients
In a large bowl, whisk 2½ cups flour, salt, baking powder, baking soda, and sugar.
Step 3: Cut in Butter
Add cold, cubed butter to dry ingredients.
Use a pastry cutter or food processor to blend until mixture resembles coarse crumbs.
Step 4: Add Wet Ingredients
In a separate bowl, whisk beaten egg and sour cream until combined.
Stir wet ingredients into flour-butter mixture until just combined.
Step 5: Add Zucchini & Cheese
Fold in drained zucchini and ½ cup cheddar cheese.
Dough will be sticky—if too wet, add 1 tbsp flour at a time.
Step 6: Shape the Scones
Turn dough out onto a floured surface; gently knead a few times.
Pat dough into an 8-inch circle about ¾-inch thick.
Cut into 8 wedges and transfer to prepared baking sheet.
Step 7: Bake
Sprinkle remaining ¼ cup cheddar cheese on top of scones.
Bake 18–22 minutes, until golden brown.
Cool slightly before serving.
Step 8: Serve
Enjoy warm with butter, a drizzle of honey, or alongside eggs or soup.
