Recipe FAQs

→ How can I ensure the crust is firm and not soggy?

Chilling the pressed dough before baking helps set the crust and prevents sogginess. Make sure your filling isn’t too wet and avoid overloading with marinara sauce.

→ Can I substitute almond flour with another low-carb flour?

Coconut flour can be used, but adjust the amount since it absorbs more moisture. Start with a third of the almond flour amount and increase if needed.

→ What other meats work well in this casserole?

Try ground turkey, chicken, or even shredded rotisserie chicken for different flavors while keeping the casserole low in carbohydrates.

→ Is fresh mozzarella better than pre-shredded?

Fresh mozzarella offers a creamier melt, while pre-shredded is convenient and melts evenly. Both work well, so it’s based on preference.

→ How do I store and reheat leftovers?

Cool thoroughly, then refrigerate in an airtight container for up to 4 days. Reheat in the oven or microwave until hot and bubbly.

→ Can I freeze this casserole?

Yes, assemble and bake, then cool completely. Wrap well and freeze up to 2 months. Thaw overnight before reheating.
