12 ounces Fresh Broccoli, cut into very large florets, 1 cup celery, 1 cup carrot
Add the celery, carrots, ONLY 2 cups of the chicken broth, salt, pepper, and broccoli florets to the inner pot of the NInja Foodi.
4 cups chicken broth, ½ teaspoon fine grind sea salt or kosher salt, ½ teaspoon black pepper
Add the butter and flour to a 6"x 2" pan and cover with foil or a silicone lid. You can use any size pressure-safe pan that fits on a rack above the soup ingredients and allows the pressure lid to go on. See the recipe article for more information. If you want to make the roux on the stove, see the recipe notes for details.
Place a rack or trivet into the pressure cooker and place the covered pan with the butter and flour on top.
Put the pressure lid on and turn the valve to seal. Select pressure cook on high and set the time for 2 minutes. When the time is up, turn the valve to vent to immediately release the pressure. When the pressure has released and the pin has dropped, you can open the lid.
Remove the pan with the flour and butter and stir to combine. The roux will be the consistency of paste.
Add the remaining 2 cups of chicken broth and the roux. Stir to break up the broccoli florets and thicken the soup base.
4 cups chicken broth

½ cup heavy cream, 8 ounces shredded sharp cheddar cheese
Stovetop Roux: In a small saucepan or frying pan, melt 4 Tablespoons of butter and stir in the flour. Cook for 2-3 minutes on medium-low heat to cook the flour. The roux will be light in color and form a loose paste. Remove from the heat and let sit until it is time to add it to the soup.
