  • 1/2 teaspoon basil
  • 1/2 teaspoon oregano
  • 2 eggs, beaten

Tips & Substitutions

For best results, choose medium-sized zucchini for a good balance of texture and flavor. If you're out of parsley, fresh basil or thyme can be great substitutes. Feel free to add some shredded carrots or bell peppers for added color and nutrients. You can also replace the crescent rolls with a gluten-free alternative if needed.

Serving Suggestions

This casserole is delicious on its own but pairs beautifully with a side salad or some Garlic Biscuits(Good With Spaghetti Or Anything) for a heartier meal. Consider serving it alongside a light soup for a comforting dinner. You can also top with a dollop of sour cream or Greek yogurt for added creaminess.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in a preheated oven at 350°F (175°C) for about 15 minutes, or until heated through. You can also microwave individual portions for 1-2 minutes, but the texture may not be as crisp.

Frequently Asked Questions

Can I make this casserole ahead of time?

Absolutely! You can prepare the casserole up to the point of baking, cover it tightly, and refrigerate for up to 24 hours. When ready to bake, just add an extra 5-10 minutes to the cooking time to ensure it's heated through.

What can I use instead of crescent rolls?

If you don't have crescent rolls, you can use puff pastry or a homemade pie crust. Alternatively, a layer of mashed potatoes or even a polenta base can work well as a gluten-free option.

Can I freeze this zucchini casserole?

Yes, this casserole freezes well! After baking, allow it to cool completely, then wrap it tightly in plastic wrap and aluminum foil. It can be frozen for up to 3 months. To reheat, thaw in the refrigerator overnight and bake until warmed through.
