Riley Reid and Jenna Foxx kick off season 3 with a dish neither have made before: crab cakes.

Riley leans into her recent cooking glow-up after ditching veganism, while Jenna trusts her instincts as a home cook. After a strong start, Riley gets confused about the rawness of eggs and Jenna forgets her slaw entirely.

Chef Jojo steps in to steady both of them, but in the final minutes it's less about perfection and more about finishing.

Chef Jojo thinks Riley's crab cakes have great texture and flavor, even if her slaw is a miss.

Jenna's dish is solid, but Chef Jojo wouldn't serve her spicy slaw to his own mother.

It's a clear win for Riley Reid... and Jenna has a choice hand gesture for Chef Jojo.

Elsa Jean and Nicole Doshi take on homemade pizza, and chaos starts before the oven even heats up.

Elsa leans into a "we'll see what happens" approach and goes on record that pineapple does belong on pizza. Meanwhile, Nicole goes more traditional with mushrooms, spicy sausage, and olives, but struggles with nerves.

As the clock winds down, Nicole's pizza collapses and instantly becomes an accidental calzone.

After sampling both pizzas, Chef Jojo is impressed by both sauces, especially given the chefs' inexperience.

Nicole's pizza-turned-calzone delivers strong flavor, but the presentation works against her. Elsa balances her controversial pineapple with the spicy kick well enough to make it work.

Unfortunately, calzones don't get bonus points. Elsa advances to the semifinals.

Leah Gotti and Violet Myers take on fried chicken and waffles with foie gras.

Although neither contestant can even pronounce foie gras, they both hunker down. Having recently binge-watched both previous seasons of This Is Fire, Violet knows that Chef Jojo loves spicy food and plans to use that to her advantage.

Leah is also planning to go the spicy route. The competition is literally heating up like never before.

When time is up, Violet and Leah are proud of what they've put on the plate. And Chef Jojo is genuinely impressed with their dishes.

In true Chef Jojo style, he keeps the pair waiting a comically long time before announcing that Violet’s dish held together better across components, while Leah’s bacon fat doesn’t fully render.

Violet's heading to the semifinals.

Arabelle Raphael and Mick Blue face off over shepherd’s pie, with Mick admitting he’s never even heard of the dish.

Early on, it's clear both will be leaning heavily on Chef Jojo for guidance. And, as they get on with their dishes, both stop to ask him basic questions several times.

Although Arabelle completely blanks on the word “fork” while Mick searches for a “potato squisher,” it's time management (not vocabulary) that becomes the problem.

In the final seconds, Arabelle forgets her peas entirely while Mick barely scrambles his in before plating.

After a particularly chaotic cook, Chef Jojo samples both dishes and determine's they're more or less tied in terms of overall quality.

Mick’s dish lands with better consistency and presentation, but Arabelle's flavors are dialed in well.

However, without her peas, Chef Jojo has no choice but to declare Mick the winner.

Chef Jojo welcomes Riley Reid and Elsa Jean back to the kitchen to kick off the semifinals. Their challenge? Chicken cordon bleu, one of the most complicated dishes in the show's history.

Neither wastes time hammering out their chicken breasts with a meat tenderizer, but Elsa is first to get hers into the deep fryer.

Her advantage is short-lived, however, when Chef Jojo gags at her cheese sauce. Riley isn't faring much better, and she worries her chicken is undercooked.

Fortunately, both Riley and Elsa manage to plate completely non-toxic food in the nick of time.

Unfortunately, Elsa's dish falls flat during the tasting. Her chicken is dry and her over-corrected cheese sauce comes out bland.

Riley's dish, however, wins Chef Jojo over in one bite. Her chicken is cooked to perfection, with perfect proportions of cheese and ham.

Riley will be heading into the finals.

Violet Myers and Mick Blue return to cook their way into a spot in the finals against Riley Reid.

Although both have been studying up since their wins, neither are prepared for today's challenge: duck breast.

With the clock ticking, Mick decides to start with his mashed potato side, and Violet starts on her glaze.

As time starts to run out, the pressure gets to both of them. Violet suddenly forgets how the kitchen sink works and Mick slices his finger with a knife.

With only two minutes remaining, Mick realizes his duck is undercooked. He hopes that cutting it into medallions will let it cook faster and keep him in the game.

Despite the drama, both manage of plate dishes worthy of any fining dining restaurant.

Chef Jojo compliments Mick on his creamy mashed potatoes and flavorful mushrooms. Violet's dish is also a hit: the mushrooms are crispy and delicious, and the duck is succulent.

In the end, while Mick's duck was salted perfectly, it was a bit overcooked. Violet advances to take on Riley Reid.

This Is Fire Season 3 culminates in a final meaty challenge: tomahawk wagyu steaks with twice-baked potatoes.

Instead of the usual half hour, Riley Reid and Violet Myers will have a full 45 minutes to cook. The catch? They won't be able to ask for Chef Jojo's help.

Violet starts on her twice-baked potato side, saving the challenge of a 48oz steak for later.

Meanwhile, Riley jumps headfirst into her steak prep, making bold seasoning choices. Chef Jojo, who is sworn to silence, can’t resist raising his eyebrow when Riley adds raw onions to the top of her steak.

Even with malfunctioning tools and a few burnt hands, both finalists finish strong plates with plenty of time left on the clock.

At the tasting, Riley's rare steak is prepared so beautifully that Chef Jojo doesn't mind how pink it is. Meanwhile, Violet's steak is cooked to perfection, and her use of roasted garlic makes her twice-baked potatoes a real standout.

After another hilariously long deliberation, Chef Jojo is finally ready to announce the winner...

Riley Reid wins the $20,000 grand prize and the title of This Is Fire Season 3 Champion. Now, can she steal the Grand Championship from Nathan Webb in the Superfinals?

Grand Champion Nathan Webb returns to battle Riley Reid for an extra $10,000 cash prize. And Chef Jojo has a surprise for this challenge: there won't be any "cooking" at all...

That's because Riley and Nathan will be preparing tuna tartare. As the challenge starts, Nathan tries to rattle Riley, but she is unflappable, and stays focused on preparing the citrus elements that will “cook” her tartare.

Meanwhile, repeats one of his old tricks from last season: copying his opponent's techniques.

As time runs out, Riley is in a full-blown frenzy trying to salvage a broken rice cake. Meanwhile, Nathan stays calm and focused, serenely tweezing garnish onto his plate.

At judging, it's obvious Nathan has the better-looking plate. However, after sampling Riley's tartare first, Chef Jojo has nothing but compliments for her use of citrus.

Chef Jojo really struggles to pick a winner, and stays quiet for what feels like eternity.

Ultimately, Nathan wins the first-ever This Is Fire triple crown.
