Sauté: Bring a dutch oven or large pot to medium-high heat. Add 2 tablespoons butter and let melt; swirl to coat the pan. Add onion and 3 tablespoons garlic. Move around pan until garlic becomes fragrant and onion softens, approx. 2 minutes.
Add Veggies: Add 1 ½ cups celery, 1 cup carrots, 1 russet potato (cubed), and 1 jalapeño (minced). Move around pan 4-5 minutes. Add the last 2 tablespoons of butter and let melt. Stir to coat the veggies. Add 3 tablespoons all-purpose flour and stir to coat the veggies again.
Simmer: Slowly add in 5 ½ cups chicken broth, approx. 1/4 cup at a time, stirring as you go. Bring to a simmer and then add 1 pound boneless skinless chicken breasts. Cover and let simmer 12-15 minutes or until chicken is fully cooked. Remove chicken from pot, shred, return to pot along with a ½ cup Frank's RedHot Wing Sauce. Stir to combine.
Cream Cheese + Seasoning: Add 4-8 ounces cream cheese and stir until melted. Add ½ teaspoon kosher salt and ⅛ teaspoon ground black pepper. Taste and add more, as-desired.
Serve: Enjoy with lots of sliced green onions and blue cheese crumbles (if desired).
Notes
Frank's RedHot Wing Sauce: if you want to use the original Frank's Red Hot, start with 1/4 cup and add more as-desired.
Chicken Thighs: feel free to sub in 1 pound of boneless, skinless chicken thighs instead of the chicken breasts.
Dairy-Free: you can sub in dairy-free butter and cream cheese to make this dairy-free (and omit the blue cheese).
Storage: Store leftovers in an airtight container in the refrigerator for up to 3-4 days.
