Transforming this Classic Greek Pastitsio. Into a gluten-free delight. Is easier than you might think. Replace the all-purpose flour in the béchamel sauce. With a gluten-free flour blend. Which thickens just as effectively. Without compromising texture. Or flavor. Additionally, swap out regular penne pasta. For a high-quality gluten-free variety. These adjustments allow everyone. Including those with gluten sensitivities. To enjoy this traditional dish. You won't miss out on any of the rich. Comforting flavors. And textures. That makes Pastitsio. A beloved classic.
