Ingredients

8 cups water
2 cups chicken or vegetable broth
3–4 medium potatoes, peeled, diced, and rinsed
2 lbs mushrooms, sliced
2 cups half & half (or 1 cup milk + 1 cup heavy cream)
4 Tbsp flour (use 5 Tbsp for a thicker soup)
1 medium onion, finely diced
1 large carrot, grated
3 Tbsp unsalted butter
2 Tbsp mushroom seasoning, or ½ Tbsp Mrs. Dash or other vegetable seasoning*
Salt and black pepper, to taste
⅓ cup chopped parsley, dill, or a mix of both

*If using regular seasoning instead of mushroom seasoning, a suggested combo is: 1 Tbsp salt, ½ tsp black pepper, and ½ Tbsp Mrs. Dash.

Instructions

Cook the Potatoes
In a large soup pot, combine water, broth, and diced potatoes. Bring to a gentle boil and cook for about 10 minutes, or until potatoes are nearly tender.
Sauté the Mushrooms
While the potatoes cook, sauté the sliced mushrooms in a dry skillet over medium-high heat until lightly browned and softened, about 6–8 minutes. Add them to the soup pot and cook for another 5–8 minutes.
Cook the Aromatics
In the same skillet, melt 3 Tbsp butter. Add diced onion and grated carrot. Sauté over medium heat for 8–10 minutes, or until golden and fragrant. Add to the soup pot.
Optional: For a smoother texture, blend the sautéed onion and carrot before adding them to the soup.
Make the Cream Base
In a small bowl, whisk together the half & half and flour until smooth. Slowly pour into the soup, stirring constantly.
Season and Finish
Add mushroom seasoning (or the alternative blend), salt, and pepper to taste. Stir in chopped herbs. Bring the soup to a gentle boil for a few minutes. Check the potatoes for doneness, then remove from heat.

Tips

Brown the mushrooms well to enhance the soup’s depth of flavor.
Stir the cream mixture thoroughly to avoid lumps.
For a thicker soup, increase flour to 5 Tbsp or simmer slightly longer after adding the cream.
For a vegetarian version, use vegetable broth and vegetable-based seasoning.

Variations and Substitutions

Dairy-Free: Use unsweetened plant-based cream and dairy-free butter.
Low-Carb: Skip the potatoes and use cauliflower florets instead.
Protein Boost: Add shredded chicken or cooked lentils.
Herb Swap: Use thyme or chives instead of parsley or dill.
