When it comes to heart, heroism, and heat, Chicago Fire never disappoints — and that includes its unforgettable weddings. Over more than a decade on NBC, the hit drama has given fans a mix of tear-jerking vows, impulsive “I do’s,” and full-blown romantic spectacles.
With Sylvie Brett (Kara Killmer) and Matt Casey (Jesse Spencer) now officially married, it’s the perfect time to look back and rank every Chicago Fire wedding — from rushed courthouse ceremonies to epic love stories on the water.
6. Joe Cruz and Chloe Allen
Season 5
No one can deny that Joe Cruz (Joe Minoso) and Chloe Allen (Kristen Gutoskie) make an adorable couple — their chemistry is pure, their love story genuine, and their little family is one of Firehouse 51’s sweetest.
Unfortunately, their wedding episode felt a little undercooked. The pacing was rushed, Chloe’s parents weren’t even there, and Stella Kidd’s role as maid of honor felt a bit forced. Compared to the emotional depth of later weddings, the Cruz ceremony came off more like a setup for future events than a moment worthy of one of 51’s most loyal members.
Still, their love story continues to be one of Chicago Fire’s most wholesome.
5. Gabriela Dawson and Matt Casey
Season 5
Ah, the wedding that time forgot. Gabriela Dawson (Monica Raymund) and Matt Casey (Jesse Spencer) had undeniable chemistry during their time together, but in hindsight, their rushed courthouse wedding feels… off.
Neither was dressed for the occasion, and the ceremony lacked the fanfare their relationship once promised. What makes it even more awkward now is that Sylvie Brett — Casey’s future wife — was in attendance. Talk about foreshadowing!
In the grand scheme, the Dawson/Casey union now feels like a prologue to the real love story that came later.
4. Wallace Boden and Donna Robbins
Season 2
The wedding of Chief Wallace Boden (Eamonn Walker) and Donna Robbins (Melissa Ponzio) remains one of the show’s most quietly powerful moments.
Boden is a man of few words, so when the team at Firehouse 51 transformed the firehouse into a makeshift chapel, it was the perfect mix of personal and profound. With Herrmann as best man and the entire crew standing by, it was a ceremony filled with loyalty and respect.
The decision to mute the vows and play music over the exchange was genius — letting emotion speak louder than words. An underrated gem.
3. Stella Kidd and Kelly Severide
Season 10
This one had it all — emotional build-up, personal growth, and pure Chicago Fire magic. Stella Kidd (Miranda Rae Mayo) and Kelly Severide (Taylor Kinney) fought their way through long-distance struggles and emotional setbacks, but when they finally tied the knot, it was worth the wait.
Set aboard a boat on Lake Michigan, their wedding was both intimate and cinematic. The intercut flashbacks of their journey — from partners-in-danger to life partners — gave longtime fans chills.
It’s the kind of wedding only Chicago Fire could pull off: romantic, reflective, and a little bit dangerous.
2. Sylvie Brett and Matt Casey
Season 12, “Port in the Storm”
After years of missed chances and emotional turbulence, Brettsey fans finally got their happy ending.
The Chicago Fire team pulled out all the stops for this one — emotional reunions, heartfelt toasts, and even a cameo from Brett’s half-sister. When Severide barely made it in time to serve as best man, it added just the right touch of chaos to an otherwise picture-perfect event.
More than anything, the episode reminded fans that Firehouse 51 isn’t just a workplace — it’s a family.
1. Trudy Platt and Mouch
Season 4
The #1 wedding in Chicago Fire history goes to Trudy Platt (Amy Morton) and Randall “Mouch” McHolland (Christian Stolte) — and for good reason.
Their ceremony perfectly balanced Chicago Fire’s signature humor and heart. Modest, unpretentious, and full of character, it captured everything fans love about the show’s tone.
Plus, this wedding gave us one of the best One Chicago crossovers ever, uniting Chicago Fire and Chicago P.D. in celebration of two of the franchise’s most down-to-earth characters.
Theirs wasn’t a flashy “TV wedding” — it was real, funny, and authentically them.
Final Thoughts
Whether it’s firehouse vows or lakefront “I do’s,” Chicago Fire weddings have always reflected the soul of the show — courage, family, and love that survives the flames.
From Mouch and Trudy’s relatable romance to Brett and Casey’s emotional payoff, these weddings remind us why Firehouse 51 has one of the most loyal fanbases on TV.
