Begin by preparing your ingredients for the Creamy White Crab Chili. Dice the white onion, bell peppers, and jalapeños, and shave the corn off the cob if using fresh. Rinse and drain the cannellini and pinto beans, ensuring they're ready to be folded into the dish later.

In an 8-quart Dutch oven, melt 2 tablespoons of butter over medium-low heat. Once melted, add the diced onion, jalapeños, bell peppers, and corn. Sauté the vegetables for about 5-7 minutes until they are tender and fragrant.

Next, pour in ¼ cup of dry sherry and 1 tablespoon of Worcestershire sauce. Use a wooden spoon to scrape any flavorful bits stuck to the bottom of the pot. Let the mixture simmer for about 2 minutes.

Now, stir in 1 teaspoon of dry mustard and 2 teaspoons of Old Bay seasoning. Gradually add 1 cup of half and half and 1 cup of heavy cream, stirring gently until well combined.

In a small bowl, whisk together 2 tablespoons of corn starch with ¼ cup of cold water to form a slurry. Slowly pour this mixture into your chili base while continuously stirring.

Gently fold in the rinsed cannellini and pinto beans, followed by 1 pound of fresh crabmeat. Heat the mixture through for another 3-4 minutes.

Ladle the Creamy White Crab Chili into bowls, garnishing each serving with shredded cheddar, fresh tomatoes, additional jalapeños, scallions, and chopped parsley.
