Ingredient Notes & Substitutions
Zucchini
Adds moisture and nutrients while reducing the need for added fat. Look for firm, medium-sized zucchinis with no soft spots.
Substitutions: You can use yellow squash or grated carrots for similar results.
Greek Yogurt
Provides tangy flavor and acts as a healthy fat substitute. Full-fat works best for moisture, but low-fat can be used.
Substitutions: Plain yogurt or sour cream can be substituted 1:1.
Lemon Zest
The bright citrus flavor is essential for these cookies. Use a microplane grater for maximum zest without pith.
Substitutions: Orange zest or lime zest can be used for a different flavor profile.
Flour
All-purpose flour gives the perfect texture. For gluten-free, use a 1:1 GF flour blend with xanthan gum.
Substitutions: Whole wheat flour can be used but will create denser cookies.

Make-Ahead Instructions & Storage
Make-Ahead Tips
Prepare the dough and refrigerate for up to 24 hours. The resting time allows flavors to develop. The dough can also be frozen for up to 2 months - just drop frozen dough balls onto baking sheet and add 2-3 minutes to baking time.
Refrigerator Storage
Store baked cookies in an airtight container in the refrigerator for up to 5 days. For longer storage, freeze baked cookies for up to 3 months. Thaw at room temperature before serving.
Freezer Storage
Place cooled cookies in a single layer in zip-top bags. Freeze for up to 3 months. For best results, separate layers with parchment paper.
Reheating Instructions
Cookies are best enjoyed at room temperature, but can be warmed in microwave for 10-15 seconds if desired.
Troubleshootingleshooting & Common Questions
Q: My cookies are too dry. What did I do wrong?
A: Zucchini can vary in moisture content. If cookies are too dry, try increasing Greek yogurt to 3/4 cup next time. Don't over-squeeze zucchini as this removes needed moisture.
Q: Can I make these gluten-free?
A: Yes! Use a 1:1 gluten-free flour blend with xanthan gum. You may need to add an extra 1/2 teaspoon baking powder for best rise.
Q: How do I prevent cookies from spreading too much?
A: Make sure oven is fully preheated. Chilling the dough for 30 minutes before baking will also help maintain shape. Use parchment paper for even baking.
Q: Can I double the recipe?
A: Yes, but bake in batches to ensure even cooking. The dough may be slightly stickier when doubled, so work quickly or chill for 15 minutes before shaping.
