- Banned Episode: Cartoon Network UK rarely aired "The Vacation" due to the Potty Emergency plot, and when they did, it was usually during the late-night hours, due to that feed's hatred of any cartoon episode that centers on a character's desperate attempts to find a bathroom.
- Children Voicing Children: Nicky Jones was 9 when he first voiced Chowder, and Panini, Gorgonzola, and Ceviche are all voiced by children. By the final season, Chowder's voice was several times deeper than it originally had been due to his voice actor hitting puberty.
- Creator Cameo: The series's creator voices Chowder in the last bits of the final episode. Carl also voices himself as a puppet in Shnitzel Quits.
- The Danza: Paul Reubens as Reuben.
- Fan Nickname: Gorgonzola has a handful of nicknames. "Gorgy" being the most popular.
- The Other Darrin:
- Shnitzel was played by Kevin Michael Richardson in the pilot episode before John DiMaggio replaced him.
- Chestnut was originally voiced by Tone Lōc (a 1990s rapper who, coincidentally, did voice work on the obscure Fox Kids cartoon C-Bear and Jamal) in his first three appearances. His replacement was also John DiMaggio.
- In the Mexican dub, Gazpacho's voice actor was replaced by his son after the original voice actor died from complications from diabetes.
- Playing Against Type: No one would expect Tara Strong to voice a cranky old woman (though the voice she uses sounds like Toot Braunstein [the hedonistic, self-harming, washed-up Betty Boop knock-off] from Drawn Together).
- Referenced by...: In the Square Root of Minus Garfield, the Garfield Ate Jon's Donut comic was turned into this version featuring Chowder and Shnitzel.
- Screwed by the Network: During the third season, the airing of new episodes were frequently delayed, Cartoon Network would often hype up new episodes in block promos when there really weren't, and later new half-hour "episodes" would be just a new episode paired with a rerun (Strangely enough, this is how CN now airs new episodes of every show).
- Unintentional Period Piece: In one episode, Chowder scribbles on the screen and gets yelled at. After it's cleaned up he points over at the Cartoon Network logo and asks "What about that one?" to which Gazpacho responds, "Ehh, that one doesn't come off. I've tried." The channel icon is part of the episode, making it obvious that the logo has changed since the episode's initial airing.
- What Could Have Been:
- One idea floating around was to have Mung falsely accused of a crime, then get together with some old friends voiced by Dirk Benedict and Mister T to prove his innocence.
- Originally Panini, who was named Borlotti, had pointed ears and an outfit in which only her face was visible. Her original character concept had her bully Chowder in a manner described by Greenblatt as similar to Angelica Pickles from Rugrats. Greenblatt removed the pointy ears since he felt this did not fit in with the rounded shapes in Chowder. Greenblatt did not like characters similar to Angelica and believed that he needed to make Panini "cuter and sweeter." Greenblatt said that the details of Panini formed when the creator decided that Panini had a crush on Chowder; since Chowder is not old enough to fall in love with females, according to Greenblatt this aspect would frustrate Chowder "in a more fun way."
- Greenblatt's blog includes a couple of episode outlines that were canned for one reason or another. One, "Messy James", was a western parody where Chowder and the other kids fight against bath time which couldn't get to air before the end of the show. Another, "The Mushroom Ball", was the story of how Truffles got her mushroom hat as a young girl, including some insight into her species, but was rejected for being "too girly".
- There were plans to do a Made-for-TV Movie about the gang going on a treasure hunt with Endive and Panini tagging along. The main villains were going to be PIE-rats, with their leader being Picana-hey (and was not only based on Matthew McConaughey, but Greenblatt wanted Matthew himself to do his voice). It ended up scrapped due to not coming along the way Greenblatt wanted and was rushed to get it done on a TV schedule.

- Years after the finale, Lil Nas X paid tribute to the show by naming his first post-fame single "Panini." He even themed the remix video after it.
