The fourth season of the American competitive reality television series Hell's Kitchen premiered on Fox on April 1, 2008, and concluded on July 8, 2008.

Ramsay considered Vanessa's pan-seared halibut "the best dish by a mile", while Rosann's spicy mussel soup was nicely seasoned and Ben's mashed potatoes and gravy were deemed "not bad".

Shayna's dish was burnt, Dominic's chicken cacciatore and roasted orzo was boring and Petrozza's Cornish hen-in-a-pumpkin was dry and bland, and the potatoes underneath were drenched in butter and oil.

Sharon's dish wasn't up to scratch, Christina's was based on a good concept but ruined by the "terrible execution", Louross was scolded for not doing more and Bobby for deep-fat frying his Hawaiian butterfish.

After the challenge, Ramsay announced that the winner of the season would become the executive chef at his brand-new restaurant at the London West Hollywood hotel.

The women quickly decided on Vanessa, while the men eventually chose Bobby, at the expense of not learning the menu for the opening night service.

Ramsay fired Vanessa as captain due to her weak leadership and had Rosann take over, and thanks to her strong guidance and Jen rebounding, the team finished appetizers, but could not serve entrees because Corey overcooked chicken.

After watching Jen's extremely long plea and Christina burst into tears, Ramsay spared them and eliminated Sharon for her second terrible service in a row, greatly upsetting Corey and shocking the other women.

Reward/punishment: Ramsay treated the women to lunch at the Saddle Ranch Chop House on the Sunset Strip, where they unintentionally met restaurant regular and season 3 contestant Aaron Song.

Craig struggled on appetizers and argued with his teammates, while Ben overcooked and undercooked salmon, angering Ramsay when he blamed his mistakes on "different cooking techniques."

Vanessa did well on appetizers, but was sent to the hospital after severely burning her hand extinguishing a fire Shayna accidentally started in a sauté pan.

The women were sent to help them, but Craig, slow-paced, bad-tempered, and uncommunicative throughout the night, yelled at his teammates, Shayna, and even Ramsay himself before finishing service.

Reward/punishment: Before leaving the kitchen to take the women on their reward, Ramsay gave the men a pep talk, saying they had talent, and only lacked teamwork.

The women were rewarded with a helicopter ride and lunch at the Square One restaurant in Santa Barbara, home of the "$90 Burger" and their truffle "fries".

After talking with Ramsay, Vanessa decided to leave Hell's Kitchen, as her injury was not likely to heal quickly, and she did not want to hinder her team by working at only half power.

Louross performed well on appetizers but had communication problems with Bobby on fish, who cooked his scallops too early, prompting Ramsay to berate the entire blue team for lacking teamwork.

Ben, meanwhile, was a complete disaster on meat: he did not respond when Ramsay called out a ticket, then undercooked chicken and claimed that he was not used to cooking on the line.

The blue team was bogged down during the challenge as a result of Jen taking most of the ingredients for herself and then trying to make Louross do a surf and turf for his dish, despite his concerns that the flavors wouldn't work.

Due to Jen and Louross's conflict over his dish, the blue team was unable to plate an ingredient in time and, therefore, automatically lost the challenge.

The blue team managed to serve all entrées successfully and received good reviews from the critics, their only problem being Petrozza slicing meat too early.

The blue team spent the day cleaning the restaurant's exterior, the flaming Hell's Kitchen sign, and the red carpet.

On the red team, Matt declined Christina's help for her pasta dish and had numerous appetizers sent back to the kitchen for being bland, too salty, and undercooked.

After he was caught sweating into the food, Christina kicked him off to go work on the garnish station where he proceeded to serve undercooked Brussels sprouts.

On the blue team, Petrozza was strong on appetizers despite being messy, however, Louross struggled on meat and had three steaks sent back to the kitchen for being undercooked.

After Louross was eliminated, Ramsay announced that Matt and Jen would return to their original teams, as he felt their reassignments were not working.

Petrozza's chicken and Matt's veal received positive feedback, but Jen's ribeye narrowly beat out Christina's sea bass for the win.

Reward/punishment: Jen won an overnight trip to Las Vegas where she had dinner at the Green Valley Ranch Resort with last season's winner, Rahman "Rock" Harper, and chose Corey to join her.

Petrozza was easily distracted by his student's physical appearance, while Jen was threatened with disqualification after twice attempting to handle the ingredients herself.

Challenge: The remaining three ate one of Ramsay's signature dishes with their loved ones (Corey's mother and boyfriend, Christina's parents, and Petrozza's father and girlfriend).

Petrozza was a strong leader despite receiving criticism for plating the dishes himself instead of asking his teammates for help, but Jen talked back to him while serving raw onion rings, though she stopped after Ramsay accused her of sabotage.
