Low-carb sausage and zucchini casserole FAQ:

What should I do if my casserole isn't bubbling after 30 minutes?

How do I store leftovers of this casserole?

Store leftovers in an airtight container in the refrigerator for up to 3-4 days. You can also freeze the casserole for up to 2 months; however, the texture may change slightly upon reheating.

What can I substitute for mayonnaise salad dressing?

Cooking Tips:

- Choose Fresh Zucchini: Opt for zucchini that are firm and free from blemishes to ensure the best texture and flavor in your casserole.

- Drain the Sausage: If using canned Vienna sausages, be sure to drain them well to prevent excess moisture in your casserole.

- Cheese Variations: Feel free to experiment with different cheeses such as mozzarella or Monterey Jack for a slightly different flavor profile.

- Bake Until Golden: Make sure to bake the casserole until the top is golden brown and bubbling for the best texture and taste.

- Serve Hot: This casserole is best enjoyed hot, so serve it straight from the oven for maximum flavor.
