Heat avocado oil in a Dutch oven over medium/high heat. Add the celery, onion, and carrot and cook for 3-4 minutes.
Next, add the minced garlic, thyme, turmeric, salt, pepper, and crushed red pepper to the Dutch oven and cook for an additional minute. Pour in the borth, coconut milk, and pumpkin puree. Whisk to mix.
Bring to a boil. Then turn the heat down to low and cover. Let simmer for 20 minutes.
Add the cheddar cheese and stir to combine. Cook for another 5 minutes.
While the soup is simmering, place the ritz crackers on a baking sheet. Place 1-2 teaspoons of blue cheese crumbles onto each cracker. Broil the ritz crackers for 1-2 minutes in the oven.
Serve each bowl with 3 blue cheese ritz crackers as garnish.
