- Yellow onion: 1 small, finely chopped
- Garlic: 3–4 cloves, minced
- Fresh thyme: 2 teaspoons leaves (or 1 teaspoon dried)
- Smoked paprika: 1/2 teaspoon (optional but great)
- Dry white wine: 1/3 cup (optional; choose a dry variety)
- Chicken or vegetable broth: 4 cups, low-sodium
- Heavy cream: 3/4 to 1 cup

- Fresh parsley or chives: for garnish

How to Make It
- Prep the mushrooms: Wipe them clean with a damp towel. Slice thick for texture or thin for a smoother blend.
If using shiitakes, remove tough stems.
- Sauté in batches: Heat a large pot over medium-high. Add 1 tablespoon butter and the oil. Add half the mushrooms and a pinch of salt.
Cook 6–8 minutes until browned. Remove to a bowl, then repeat with remaining mushrooms using 1 tablespoon butter.
- Cook the aromatics: Lower heat to medium. Add the final tablespoon of butter.
Sauté onion 3–4 minutes until soft. Stir in garlic, thyme, and smoked paprika for 30 seconds until fragrant.
- Deglaze: Pour in the white wine, scraping up any browned bits. Let it reduce by half, about 1–2 minutes.
If skipping wine, use a splash of broth and a squeeze of lemon later.
- Simmer: Return all mushrooms to the pot. Add broth. Bring to a gentle simmer and cook 10 minutes to meld flavors.
- Blend to your texture: For silky soup, use an immersion blender right in the pot.
For mixed texture, blend half the soup and return it. For chunky, skip blending.
- Make it creamy: Reduce heat to low. Stir in heavy cream and cream cheese until smooth.
If needed, whisk or briefly blend to fully incorporate the cream cheese.
- Season: Taste and adjust with salt and pepper. Add a splash of coconut aminos or tamari for umami, and a small squeeze of lemon for brightness if you like.
- Finish and serve: Ladle into bowls. Garnish with chopped parsley or chives and a crack of black pepper.
A drizzle of olive oil or a dollop of sour cream is a nice touch.
How to Store
- Refrigerator: Cool completely, then store in an airtight container for up to 4 days.
- Freezer: Cream soups can separate when frozen. If you plan to freeze, blend the soup and skip the cream and cream cheese. Freeze up to 2 months.
Reheat gently, then stir in cream and cream cheese at the end.
- Reheating: Warm over low heat on the stove, stirring often. Avoid boiling to prevent curdling.
Health Benefits
- Low in carbs: Mushrooms and aromatics keep net carbs low while delivering a hearty, satisfying bowl.
- High in healthy fats: Cream and butter provide sustained energy and help keep you full on a keto plan.
- Micronutrient rich: Mushrooms offer B vitamins, selenium, and antioxidants that support immune and metabolic health.
- Gluten-free without effort: No flour, no roux—just natural thickness from cream cheese and blending.
What Not to Do
- Don’t overcrowd the pan: Mushrooms steam instead of brown, and you’ll lose flavor. Cook in batches.
- Don’t boil after adding cream: High heat can cause separation.
Keep it to a gentle simmer or below.
- Don’t skip salt: Mushrooms need proper seasoning to shine. Taste at the end and adjust.
- Don’t use sweet wine: It can throw off the balance. Choose dry or use broth and lemon instead.
- Don’t add starchy thickeners: They raise carbs.
Use cream cheese and blending for body.
Variations You Can Try
- Truffle touch: Add a few drops of truffle oil just before serving. A little goes a long way.
- Bacon and leek: Crisp 3 strips of bacon, remove, and cook sliced leeks in the drippings. Crumble bacon on top.
- Roasted garlic: Roast a whole head of garlic and squeeze the sweet cloves into the soup before blending.
- Coconut cream version: For dairy-light, swap heavy cream with full-fat coconut cream and use ghee or olive oil.
Flavor stays rich with a subtle coconut backdrop.
- Protein boost: Stir in shredded rotisserie chicken or browned ground turkey near the end.
- Herb twist: Swap thyme for rosemary or tarragon. Finish with fresh dill for a bright pop.
- Spicy kick: Add red pepper flakes or a pinch of cayenne with the garlic.

Can I make it dairy-free?
Use olive oil or ghee, swap heavy cream for coconut cream, and omit cream cheese or use a dairy-free alternative. Blend well to keep it silky.

A mix gives the best flavor. Cremini or baby bella for depth, white button for bulk, and a handful of shiitake or oyster for umami and texture.
