Instant Pot (Pressure Cooker) Method
Combine vegetable stock, wild rice, mushrooms, garlic, carrots, celery, sweet potato, onion, bay leaf and Old Bay seasoning in the bowl of an Instant Pot pressure cooker. Stir briefly to combine.
Cover and set vent to �sealing�. Cook on manual (high pressure) for 25 minutes. Let the Instant Pot rest there for an extra 10 minutes (natural release). Then carefully turn the vent to �venting� and release the remaining pressure (quick release). Remove lid and discard the bay leaf.
Meanwhile, during those final 10 minutes of pressure cooking, prepare your cream sauce on the stove. In a medium saucepan, cook the butter over medium-high heat until melted. Whisk in the flour until combined, and cook for 1 minute. Gradually add in the milk, and whisk until combined. Continue cooking, stirring frequently, until the mixture nearly comes to a simmer and has thickened. (It should be very thick.)
Add the cream sauce and kale to the soup, and stir gently until combined. Taste and season with salt and pepper (plus any extra Old Bay seasoning, if you would like) as needed.
Serve warm. Or transfer to sealed container(s) and refrigerate for up to 4 days.

Stovetop Method
Heat 1 tablespoon butter in a large stockpot over medium-high heat, add onion and saut� for 5 minutes, stirring occasionally, until soft and translucent. Stir in the garlic and cook for an additional 1-2 minutes, stirring occasionally, until fragrant.
Add in the vegetable stock, wild rice, mushrooms, carrots, celery, sweet potato, bay leaf and Old Bay seasoning. Stir to combine.
Continue cooking until the soup reaches a simmer. Then reduce heat to medium-low, cover and simmer for 45 minutes, or until the rice is tender, stirring occasionally.
Meanwhile, during those final 10 minutes, prepare your cream sauce in a separate saucepan on the stove. In it, cook the butter over medium-high heat until melted. Whisk in the flour until combined, and cook for 1 minute. Gradually add in the milk, and whisk until combined. Continue cooking, stirring frequently, until the mixture nearly comes to a simmer and has thickened. (It should be very thick.)
