Introduction

Ingredients
- 1 8 oz. can refrigerated crescent rolls
- 2 Tbsp. butter
- 1 small onion, chopped (approx. 1 cup)
- 4 cups chopped zucchini (approx. 4 small zucchini)
- 3 eggs
- 1 tsp. dried basil
- 1 tsp. dried oregano
- 1 tsp. dried mustard
- 1/2 tsp. salt
- 1/4 tsp. pepper
- 8 oz. shredded mozzarella cheese
Instructions
- Step 1: Press the crescent roll dough into a greased 8×8 inch baking pan to form the crust.
- Step 2: Melt the butter in a medium skillet over medium heat. Add the chopped onion and zucchini and sauté for about 5 minutes, until the vegetables are tender-crisp.
- Step 3: In a medium mixing bowl, beat the eggs thoroughly. Stir in dried basil, oregano, mustard, salt, and pepper.
- Step 4: Gradually add a small amount of the warm onion and zucchini mixture to the eggs to temper them, then combine with the remaining vegetables. Stir well.
- Step 5: Fold in the shredded mozzarella cheese until evenly mixed.
- Step 6: Pour the filling evenly over the unbaked crescent roll crust. Bake in a preheated oven at 400°F (200°C) for 25-30 minutes, until the top is golden and set.
Tips & Variations
- Try swapping mozzarella for sharp cheddar or pepper jack for a different cheesy flavor.
- Fresh herbs like thyme or parsley can be added for extra freshness.
- For a lower-carb crust, consider using a cauliflower crust instead of crescent rolls.
- Be sure not to overcook the zucchini in the skillet; tender-crisp keeps the bake from becoming too watery.
Storage
Store leftover bake in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) for 10-15 minutes or in the microwave until warmed through.

FAQs
Can I use frozen zucchini instead of fresh?
Fresh zucchini works best for this bake because frozen zucchini tends to release more water, which can make the dish soggy. If using frozen, be sure to thaw and squeeze out excess moisture before cooking.
Can I prepare this dish ahead of time?
Yes, you can assemble the bake and refrigerate it for a few hours before baking. Allow for an extra few minutes in the oven if baking straight from the fridge.

Ingredients
Crust
- 1 8 oz. can refrigerated crescent rolls
- 2 Tbsp. butter
Filling
- 1 small onion, chopped (approx. 1 cup)
- 4 cups chopped zucchini (approx. 4 small zucchinis)
- 3 eggs
- 1 tsp. dried basil
- 1 tsp. dried oregano
- 1 tsp. dried mustard
- 1/2 tsp. salt
- 1/4 tsp. pepper
- 8 oz. shredded mozzarella cheese
Instructions
- Prepare the crust: Press the refrigerated crescent roll dough evenly into a greased 8×8 inch baking pan, making sure to cover the bottom and sides to form the crust.
- Sauté vegetables: In a medium skillet, melt the butter over medium heat. Add the chopped onion and chopped zucchini, and sauté for about 5 minutes until the vegetables are tender-crisp but still retain some texture.
- Mix eggs and spices: In a medium mixing bowl, beat the three eggs thoroughly, then stir in the dried basil, oregano, mustard, salt, and pepper evenly into the mixture.
- Temper eggs with vegetables: Add a small amount of the warm onion and zucchini mixture into the egg mixture to temper the eggs, preventing curdling, then combine the rest of the sautéed vegetables into the egg mixture and stir well to blend all ingredients.
- Add cheese: Stir in the shredded mozzarella cheese into the combined vegetable and egg mixture until evenly distributed.
- Assemble and bake: Pour the zucchini, egg, and cheese mixture into the prepared crescent roll crust, spreading it evenly. Bake in a preheated oven at 400°F (204°C) for 25 to 30 minutes until the filling is set and the crust is golden brown.
Notes
- For best results, use firm zucchinis and avoid overcooking the sautéed vegetables to maintain texture.
- Feel free to substitute mozzarella with other mild cheeses like Monterey Jack or provolone for variation.
- Let the bake cool slightly before slicing to allow it to set for cleaner pieces.
- This dish can be served warm or at room temperature, making it versatile for any meal.
- Adding a sprinkle of freshly chopped parsley or basil on top before serving can enhance freshness.
