It’s one of those words. You start typing it, your thumb hovers over the keyboard, and suddenly the vowels look like a scrambled mess. How do you spell casserole? It seems simple enough until you’re halfway through and realize you aren't sure if there's a double "s," a double "l," or maybe some rogue "a" hiding in the middle. Honestly, it happens to the best of us, especially when we’re just trying to label a Tupperware container before shoving it into the freezer.
C-A-S-S-E-R-O-L-E.
That’s it. Seven letters. No "a" in the middle, despite how it sounds when some people say "cass-a-role." It’s a French word by origin, which usually means there are too many letters for the sound we're actually making, but in this case, it’s relatively straightforward once you see the pattern.
Why the spelling of casserole trips us up
We struggle because English is a linguistic junk drawer. We steal words from everywhere and then get annoyed when they don't follow our rules. The word "casserole" comes directly from the Old French word casserole, which is a diminutive of casse. That refers to a large ladle or a pan. If you go back even further, you hit the Latin cattia, which basically meant a basin or a vessel.
Language is weird.
The most common mistake people make when wondering how do you spell casserole is adding an extra "a." You’ll see "cassarole" on handwritten recipe cards from the 1970s all the time. It’s a phonetic trap. Because we often neutralize that middle vowel when speaking—turning it into a "schwa" sound—our brains want to slot an "a" in there. But stick to the "e." Think of it like "role," as in playing a role in a play, though the etymology isn't related. It’s just a helpful memory trick.
Then there’s the double "s." Sometimes people try to get away with "caserole." That looks like it should rhyme with "case" or "phase." We need those two S’s to keep the vowel short and snappy.
The dish versus the pan
Here is where it gets slightly more complex. When you ask how do you spell casserole, are you talking about the food or the thing you cook it in?

In the culinary world, the word is a "contronym" of sorts—or at least a word with a dual identity. It is both the vessel and the contents. This isn't just a quirk of American English; it’s baked into the history of the kitchen. According to food historians like Jean Anderson, the concept of the casserole as we know it—a unified, slow-cooked meal served in the same dish it was baked in—didn't really explode in the United States until the early 20th century.
Before that, you had "baked dishes." But then came the industrial revolution.
Suddenly, companies like Pyrex (which introduced its borosilicate glass in 1915) were marketing specific "casserole dishes." These were durable, easy to clean, and looked nice enough to put on a dining room table. The name of the pot eventually became the name of the meal. It was a branding masterstroke. If you look at mid-century cookbooks, the spelling is remarkably consistent, even if the ingredients—looking at you, tuna noodle—were chaotic.
Regional variations and "Hotdish"
If you’re in Minnesota or North Dakota, you might not even be asking how do you spell casserole because you're busy spelling "hotdish."
Is there a difference?
Basically, no. But also, yes. A hotdish is a specific subset of the casserole family tree. It almost always requires a protein, a vegetable, a starch (usually Tater Tots or noodles), and a "binder," which is almost exclusively a cream-based canned soup. Campbell’s Cream of Mushroom soup is essentially the glue that held the American Midwest together for fifty years.
While "casserole" feels a bit more formal—something you might bring to a brunch—"hotdish" is the functional, utilitarian cousin. But regardless of the name, the spelling of the French-rooted term remains the standard in dictionaries from Merriam-Webster to Oxford.

If you’re writing a menu or a blog post, here are the variations you will likely see—and why they are technically "wrong" according to standard English:
- Cassarole: The most common misspelling. It’s phonetic but incorrect.
- Casseroll: People think of a "roll" (like bread), but this isn't a bakery item.
- Caserole: Lacks the double "s" needed to keep the "a" short.
- Casserol: Forgetting the silent "e" at the end.
The evolution of the one-pot meal
The reason we care about how do you spell casserole is that the dish refuses to die. It’s the ultimate comfort food. It survived the 1950s era of gelatin-encased nightmares, the 1980s obsession with microwave cooking, and the modern era of "clean eating" where it has been rebranded as "meal prep."
In the 19th century, casseroles were often sophisticated French affairs involving rice and molded meats. They were fancy. They were "cheffy."
Then the Depression hit.
Suddenly, the casserole was a way to stretch a very small amount of meat to feed a very large family. You throw in some rice, some leftover veggies, and whatever liquid you have, and you’ve got a meal. It was survival. It was efficiency. By the time the 1950s rolled around, it became a symbol of the "modern" suburban housewife who could spend less time over a stove and more time doing... well, whatever 1950s housewives did in commercials.
Modern spelling in the digital age
Nowadays, Google’s autocorrect usually catches you if you mess up. But search engines are still seeing thousands of hits for the misspelled versions every single month. This tells us that our collective memory of French-derived spelling is a bit shaky.
If you're a food blogger or a recipe creator, getting the spelling right matters for E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness). If a reader sees "Best Tuna Cassarole Recipe," they might subconsciously wonder if you know how to cook if you don't know the name of the dish. It's a small detail, but details are everything in the kitchen.

Interestingly, the word "casserole" is also used in different contexts globally. In some parts of the UK and Australia, it might refer specifically to a stew cooked in the oven, whereas in the US, it almost always implies a dish that is thick, perhaps topped with cheese or breadcrumbs, and not quite "soupy."
How to remember the "E"
Think of the word "Erode." A casserole is often something that gets "eroded" as people scoop out servings. Or, more simply, think of "Eat." You eat a casserole. If you can remember that it starts with an "e" in the second half, you’re golden.

Putting it to use
Now that you’ve mastered the spelling, you’re ready to actually use the word. Whether you are labeling a freezer meal for a friend who just had a baby or you’re writing out a grocery list for a Sunday potluck, you can do it with the confidence of a linguist.
Actually, don’t just write it. Cook it.
The beauty of the casserole is its forgiveness. You don't need a scale. You don't need a degree from the Cordon Bleu. You just need a deep dish and a dream.
Actionable Next Steps:
- Check your digital recipes: Go through your Pinterest boards or digital notes and fix any "cassarole" typos to make your searches more effective.
- Label clearly: When freezing leftovers, use a permanent marker and write "CASSEROLE" in all caps. It helps with recognition when the lid gets frosty.
- Master the ratio: For a perfect dish every time, follow the 1-2-3 rule: 1 part protein, 2 parts vegetables, 3 parts starch/binder.
- Try a non-traditional version: Look into "Enchilada Casseroles" or "Breakfast Casseroles" to see how the spelling remains the same even when the flavor profile shifts from French to Mexican or American styles.
The next time someone asks you how do you spell casserole, you won't just give them the letters. You’ll give them a history lesson. Or maybe just a plate of food. Most people prefer the food.
