Ingredients You’ll Need for Keto Cream of Mushroom Soup

Save

Grab these bad boys—no weird specialty items, promise:

2 tbsp butter (because everything’s better with butter, duh)
1 medium onion, finely chopped (the sneaky flavor base—don’t skip!)
2 cloves garlic, minced (garlic is life, fight me)
16 oz (about 1 lb) fresh mushrooms, sliced or chopped (button, cremini, whatever—go wild, but fresh > canned)
4 cups chicken broth (or veggie broth if you’re feeling plant-powered)
1 cup heavy whipping cream (the star of the creamy show)
4 oz cream cheese, cubed (hello, thickener without carbs!)
1 tsp dried thyme (or fresh if you’re fancy)
Salt and black pepper to taste (be generous—mushrooms love salt)
Optional: a splash of sherry or white wine for that je ne sais quoi (keto-friendly in small amounts)

That’s it. No flour, no cornstarch, no drama.

Step-by-Step Instructions

keto cream of mushroom soup making process

Save

Melt the butter in a large pot or Dutch oven over medium heat. Add the chopped onion and sauté until it’s soft and translucent, about 4-5 minutes. Don’t let it brown unless you want onion soup instead.
Add the minced garlic and mushrooms. Stir everything around like you’re giving them a little massage. Cook for 8-10 minutes, until the mushrooms release their liquid and start to brown. They’ll shrink like crazy—it’s normal, don’t panic.
Pour in the chicken broth and add the thyme, salt, and pepper. Bring it to a gentle boil, then reduce to a simmer for 10 minutes. Let those flavors mingle and get happy.
Drop the cream cheese cubes and stir until it melts completely. Pro tip: cube it small so it melts faster—no one wants lumpy soup.
Slowly stir in the heavy cream. Simmer another 5-10 minutes until it’s thickened to your liking. Taste and adjust seasoning—maybe more salt or a grind of pepper.
Optional: For ultra-smooth vibes, use an immersion blender to purée half or all of it. Chunky? Leave it as is. Your call, chef.

Serve hot, maybe with a swirl of extra cream on top for that Instagram glow-up. Boom—done.

Common Mistakes to Avoid

Dumping in the cream too early or on high heat — it can curdle faster than you can say “oops.” Keep the heat gentle once dairy’s involved.
Using old mushrooms — they turn slimy and sad. Fresh ones should feel firm and smell earthy, not like a damp basement.
Forgetting to season layer by layer — mushrooms soak up salt like sponges. Taste as you go, or you’ll end up with bland soup. Rookie move.
Boiling like it’s pasta water — simmer, don’t rage-boil. Dairy hates drama.
Skipping the taste test — always taste before serving. Add more thyme or pepper if it’s missing that something.

Alternatives & Substitutions

No heavy cream? Use half-and-half if you’re okay with slightly fewer fats, but heavy cream is king for max creaminess and keto points.
Dairy-free keto? Swap butter for avocado oil, use coconut cream instead of heavy cream, and a dairy-free cream cheese alternative. It won’t be identical, but it’ll still slap.
Mushroom variety — Mix in shiitake or portobello for a deeper flavor. All white buttons? Totally fine—classic and mild.
Thicker soup — Add ¼–½ tsp xanthan gum if you want it condensed-style (like the canned version). Stir it in well to avoid clumps.
Extra umami — A splash of Worcestershire (check for sugar) or soy sauce/tamari boosts savoriness without carbs.

IMO, the onion + garlic + thyme combo is non-negotiable for that cozy feel, but experiment—you do you.

FAQ

Can I make this ahead and freeze it?

Yep! Cool it completely, portion into freezer bags or containers, and freeze for up to 3 months. Thaw overnight in the fridge and reheat gently on the stove (stir often to avoid separation). Tastes just as good.

Is this soup really low-carb?

Heck yes—about 5-7g net carbs per serving, depending on your exact portions. Way better than the canned stuff that’s loaded with hidden starches.

Can I use dried mushrooms instead?

Sure, but rehydrate them first and use the soaking liquid as part of the broth for bonus flavor. Fresh is easier and more consistent, though.

What if I’m not a fan of chunky bits?

Blend the whole thing! An immersion blender makes it silky-smooth restaurant style. Or leave it chunky for texture—both are delicious.

Can I add protein to make it a full meal?

Totally! Shredded chicken, crumbled bacon, or even ground sausage are sautéed first. Turns it into hearty keto chowder vibes.

Why does my soup taste bland?

You probably under-salted. Mushrooms need salt to shine. Also, taste after adding broth and again after cream—adjust as needed.

Is this gluten-free, too?

100%—no flour or thickeners with gluten. Just pure goodness.
