Quick answer

Correct: Brussels sprout (1) / Brussels sprouts (2+). Incorrect: brussel sprout, brussel_sprout, brussels-sprout (as a noun).

Keep the city spelling: Brussels (capital B, ends with s).
Use sprout (singular) or sprouts (plural) like any count noun.
Hyphenate only when the phrase is a compound modifier before another noun and you want to avoid ambiguity.

Core explanation: origin, capitalization, pluralization

The name comes from the city Brussels. When a place name modifies a noun, preserve the place-name spelling and capitalization: Brussels sprout(s).

Pluralize and use articles as usual: a Brussels sprout (one); Brussels sprouts (more than one).

Place name + noun → keep place-name spelling: Brussels sprout(s).
Capitalize Brussels in running text; only capitalize sprouts in title case.
Treat singular/plural like any count noun: a Brussels sprout; Brussels sprouts are seasonal.

Spacing and hyphenation: short rules and examples

Default: two words - Brussels sprout / Brussels sprouts. Avoid joined forms or underscores used in code or casual typing (brussel_sprout).

Hyphens are optional when the phrase functions as a compound modifier before a noun. Follow your style guide and be consistent.

No hyphen (noun): I love Brussels sprouts.
Optional hyphen (modifier): Brussels-sprout tart or Brussels sprout tart - both work; hyphen adds clarity.
Avoid underscores and dropped letters: wrong → brussel_sprout, brussel-sprout, brussel sprout.

Grammar quick checks: articles, agreement, and count

Use a/an for singular: a Brussels sprout. Use the plural for general statements: Brussels sprouts are in season.

Watch subject-verb agreement in container phrases: "A bowl of Brussels sprouts is on the table" (bowl is singular).

Singular: a Brussels sprout; the Brussels sprout I tried.
Plural general: Brussels sprouts are healthy.
Collective agreement: A plate of Brussels sprouts was served (plate = singular).

FAQ

Is it brussel sprout or Brussels sprout?

Use Brussels sprout (singular) and Brussels sprouts (plural). "Brussel sprout" without the final s is incorrect.

Do I capitalize "Brussels sprouts"?

Capitalize Brussels because it's a proper noun. In running text: Brussels sprouts. In title case: Brussels Sprouts.

Should I hyphenate "Brussels-sprout" when used before another noun?

Hyphenation is optional for compound modifiers: Brussels-sprout tart can be hyphenated for clarity, but Brussels sprout tart is also acceptable. Be consistent with your style guide.

Which is correct: "A plate of Brussels sprouts are" or "is"?

Use "is" because the subject is the plate: "A plate of Brussels sprouts is on the table." If the subject is the sprouts, use "are": "Brussels sprouts are on the plate."

How can I remember the correct spelling every time?

Use the mnemonic "Brussels = buses" and run the three quick checks: place-name spelling, singular/plural, and hyphenation. When unsure, copy the phrase from a reliable source.
