STEP-BY-STEP INSTRUCTIONS FOR MAKING MUSHROOM SOUP RECIPE
First Step: Prepare Ingredients
First, prepare all the needed ingredients. Clean and chop the mushrooms to your desired size, and cut the onions into small pieces.
Second Step: Saute Onions and Mushrooms
Prepare your cooking pot and saute the onions in the melted butter until caramelized. Add the mushrooms and cook until they release their moisture.
Third Step: Add Broth and Cream
Once the onions and mushrooms are cooked, add the cream, bone broth, and salt and pepper. Bring the mixture to a boil, reduce to medium heat, and let it simmer for about 10 minutes.

TIPS FOR MAKING LOW CARB CREAM OF MUSHROOM SOUP:
- Mushroom Variety: Mix different mushroom types like cremini, shiitake, or portobello for a richer flavor. Sauté them first to bring out their natural, earthy taste.
- Creamy Texture: Use heavy or coconut cream for a smooth, rich texture. Add it slowly to control how thick and creamy you want the soup to be.
- Seasoning Boost: Add a dash of garlic, onion powder, or even a splash of Worcestershire sauce for extra depth in flavor.
- Thickening Without Flour: Instead of flour, blend a portion of the cooked mushrooms with broth to naturally thicken the soup. This trick keeps it low carb and adds to the creaminess.
- Garnish: Add crispy bacon bits, fresh thyme or fried mushroom slices on top for a delicious crunch and a gourmet touch.
