Sprinkle the zucchini with salt and let it drain for 30 minutes. After draining, squeeze out the excess moisture. Place the zucchini in a medium bowl.

Spoon marinara sauce over the sausage-zucchini mix. Layer with cheese and desired toppings. Save some cheese to sprinkle on top so that everything stays in place during cooking.

Common Mistakes to Avoid
Making a Keto Pizza Casserole can be simple, but there are a few common mistakes to watch out for.
- Not draining the zucchini properly: Failing to squeeze out excess moisture can lead to a soggy casserole. Always salt and let it drain adequately.
- Using high-carb marinara sauce: Not all marinara sauces are keto-friendly. Check labels for added sugars and opt for low-carb options like Rao’s.
- Overcooking the sausage: Cooking the sausage for too long can dry it out. Aim for just cooked through to keep it juicy.
