Ingredients
Instructions
- Line a 13 x 9-inch dish with crescent rolls, sealing perforations.
- Layer cooked and drained sausage, sliced mushrooms, and half the cheese on top of the crescent rolls.

- Sprinkle remaining cheese on top.
- Chill the casserole overnight.

Tips & Substitutions
For added flavor, consider using different types of cheese such as cheddar or pepper jack instead of Monterey Jack. You can also substitute the sausage with turkey sausage or a plant-based alternative for a lighter option. If you prefer a vegetarian dish, omit the sausage and add extra mushrooms or spinach. To save time, use pre-cooked sausage or frozen vegetables. Chill overnight for better flavor absorption.

Frequently Asked Questions
Can I make this casserole ahead of time?
Yes, you can assemble the casserole the night before and store it in the refrigerator. Just follow the instructions up until baking, then cover and chill. When you're ready to bake, remove it from the fridge and let it sit at room temperature for about 30 minutes before baking to ensure even cooking.
What can I substitute for cream of onion soup?
If you don’t have cream of onion soup, you can use cream of mushroom soup or make a homemade version by combining sautéed onions, cream, and a bit of broth. Alternatively, a mixture of sour cream and onion powder can work well for a similar flavor profile.
Can I add other vegetables to the casserole?
Absolutely! Feel free to incorporate other vegetables like bell peppers, spinach, or zucchini for added nutrition and flavor. Just make sure to cook any raw veggies beforehand to avoid excess moisture in the casserole.
