How to Make Cheesy Baked Zucchini Casserole
Preheat your oven to 400 °F (204 °C). This ensures even cooking for the casserole, creating that perfectly golden top you ll love.
Grease an 8 8 baking dish with cooking spray or butter. This step keeps your casserole from sticking and makes for easier serving later on.
Roll out the crescent dough into the baking dish, pressing it to cover the bottom. This flaky base adds delicious texture to your Cheesy Baked Zucchini Casserole.
Melt butter and olive oil in a large skillet over medium heat; add chopped onions and zucchini. Cook until tender, about 7 minutes, stirring occasionally. Remove from heat when soft but not mushy.
Whisk together the eggs, heavy cream, garlic powder, parsley, oregano, salt, and pepper in a separate bowl. This mixture acts as the binder, bringing all the fantastic flavors together.
Combine the egg mixture with the saut ed zucchini, adding in both cheeses. Stir until everything is well-mixed and coated for that ultimate cheesy bliss.
Pour the mixture over the crescent rolls in the baking dish, spreading it evenly. Every bite should be filled with creamy goodness and cheesy delight!
Bake for 40-45 minutes, or until the top is slightly browned and the casserole is set. A golden top indicates it s ready to be enjoyed!
