We try to keep these in the house. They are REALLY nicely sized and work great for soups. They are AWESOME for soups and the only disposable plates I feel comfy using for large stews and such. Makes cleaning easy because I don't HAVE TO CLEAN! They are a bit more expensive than otherd disposable plates, but they are worth it. Pretty heavy duty plates that are thick and great for heavier foods. <3

Favorite compostable plates ever!

I’ve been using the Dixie Ultra Extra Large Compostable Paper Bowls, and I can honestly say I absolutely love them! They’re sturdy, deep, and hold generous portions, perfect for everything from hearty soups and pasta to big salads or even snacks for movie night. Unlike other paper bowls, they don’t get soggy or collapse, even with hot or liquid-heavy foods. Another huge plus for me is that they’re compostable, so I can enjoy the convenience of disposables without the guilt. They’re strong, reliable, and environmentally friendly, which is a rare combo! If you’re looking for durable, eco-conscious paper bowls that can handle anything you throw in them, these are a must-have. Highly recommend!
