NICE for soups!
Style: 34 Ounces, Size: 34 Count
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!
Style: 34 Ounces, Size: 34 Count, Style: 34 Ounces, Size: 34 Count
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!

No more washing pozole/menudo bowls for me
Style: 34 Ounces, Size: 34 Count
Very sturdy for a paper plate. Used these for pozole at a party and saved me the hassle of washing plates. Good size, bigger than you think. When serving it does get hot so use something underneath so you don’t get burned.

Extra large paper bowls are sturdy, affordable, and make clean up a breeze.
Style: 34 Ounces, Size: 34 Count
I like the convenience of paper plates and these large 34 oz. bowls are perfect for microwave cooking. They are deep enough to handle soup, pasta, stuffing and vegetable sides with no problems and without any leaking, and are a good value for the price. They look stylish and make clean up less of a chore. You can't go wrong with Dixie paper products. They're sturdy, fun, and last through the meal.
