This keto mushroom soup recipe is easy to make and can be used in any recipe calling for a can of condensed cream of mushroom soup! Plus, it is also gluten-free and with a few simple swaps can also be whole30, vegan, and paleo-compliant!
Now that casserole season is here, you definitely don't want to miss this easy keto condensed cream of mushroom soup recipe!
It's easy to prepare, doesn't have the junk ingredients of the canned stuff, and is Keto and allergy-friendly! I'm talkin' to you, Keto Green Bean Casserole, lol!
Ingredients
Here are the simple ingredients you will need:
- Butter - For buttery goodness and sauteing the veggies.
- Onion - For flavor.
- Mushrooms - Because you have to have mushrooms in mushroom soup!
- Garlic - Garlicky goodness.
- Chicken Broth - Used the thin the soup and add flavor.
- Heavy Cream - Makes the low-carb soup rich and creamy.
- Ground Thyme - Adds SO MUCH yummy flavor, do not skip it!
- Salt & Pepper - Seasonings, to taste. If the soup tastes "flat", it needs more salt.
Easy instructions
Start by cooking onion, garlic, and an 8 oz. package of sliced mushrooms in some butter or oil until nice and tender.
After that, stir in ½ Cup of heavy cream, ¾ cup of chicken broth, thyme, salt, and pepper, and let it bubble a bit.
To thicken the soup
To thicken the soup, just transfer it to a blender and blend until smooth. This will make it thicken up nicely. If you would like a little bit of texture, simply reserve some of the mushrooms and stir them in after blending.
Another way to thicken the soup is by mixing 3 Tbsp. of tapioca flour with 3 Tbsp. of cold water. Then, pour the slurry into the boiling soup and stir until thickened - about 1 or 2 minutes.
This method thickens nicely and works well too, but has added carbs and starch so I prefer the blended method.
If you do use this method, steer clear of arrowroot because it loses its thickening power under prolonged heat so it will not work well if you're using the recipe for a casserole. Also, you may want to cut or break up your mushrooms a bit more.
I hope you're able to use this recipe to make all kinds of awesome recipes and casseroles. Please let me know what you think in the comment section below!!!
Storage
- Store: Store in the fridge for up to 3 days.
- Freeze: Freeze in a freezer-safe container for up to 3 months.
- Reheat: Allow the keto soup the thaw (if needed) and then come to room temperature. Then, reheat gently on the stove.
Substitutions
This recipe is gluten-free, keto, and low-carb. Here are some substitutions to make it fit more diets:
- Whole30, Dairy-Free & Paleo: Use non-dairy butter or ghee for Paleo and Whole30, and replace the heavy cream with well-shaken full-fat canned coconut milk. I don't recommend keeping the coconut milk in the fridge for this recipe. If the coconut cream is cold, it will separate and be hard to stir. If it's hard to stir, simply place it in a microwaveable bowl and heat for a few seconds, or just until soft.
- Vegan: Replace the butter with non-dairy butter, the chicken broth with vegetable broth, and the heavy cream with full-fat canned coconut milk.
Top tips
- This recipe is equal to 1 10.5 oz can of condensed cream of mushroom soup.
- If eating as soup and not used in place of a can of soup in a recipe, you will need to thin it out with broth to the desired consistency.

I made this recipe. It is absolutely delicious. I love mushrooms, and soups, just stirred into other recipes, so this was great. Thank you!

Cream of mushroom soup does not have onions!
Cassidy Stauffer says
Hi SW,
Not all recipes are the same. Some cream of mushroom soup recipes have onions and others do not. In this recipe, I like the flavor that the onions lend. If you prefer, you can leave them out.

Great recipe! Made it for The green bean casserole for Thanksgiving. Absolutely delicious! I had to keep tasting it & plan to have it for dinner one night … but not this week! I was wondering if I could freeze it?
Thanks & have a lovely Thanksgiving 🙂
Cassidy Stauffer says
Oh YAY thank you, I'm so happy you like it!!!
I haven't tried freezing it myself, but I'd imagine it would freeze nicely 😀
XO,

Judy says
I want to make the soup, not the condensed version. Can I eat it as is, or should I add more liquid of some kind?
I hope to make this next week. Looking forward to your reply. I am new to dairy free and gluten free, and this would be so nice!
THANK YOU!

Hi Judy!
To eat as a soup, you can just thin it out with some chicken broth until it reaches the right consistency 🙂 I'm excited for you to try this, please come back and let me know what you thought!
XO,
Cassidy
Judy says
Sounds great, Cassidy! We look forward to trying it.
I’ve tried other cream of mushroom recipes, but they were much too thin. I love that I can moderate the texture. I might add more mushrooms, though.
Thanks for the tips on the more neutral tasting canned coconut milks.
I wonder how adding oatmilk would work out.
Mera says
Thanks for posting this recipe - it will make converting some family favorites to a paleo version much easier! I live in Hot Dish Land, so almost every recipe calls for condensed cream of mushroom soup.
JaimeS says
Could you make this in a few batches and freeze it so you have it for a quick addition to a meal rather than making it every time?
Cassidy says
Hi JaineS!
While I think you could, I just couldn't say for sure because I haven't tried it - sorry! If you thicken it with gluten free flour I wouldn't recommend it as it doesn't always re-heat well, but I *think* if you use the recipe as written it should be OK. If you try it come back and let me know how it worked!!!

Karen says
Yes! It freezes well and is absolutely wonderful when used after being frozen. I make several batches at once and freeze for convenience. Works like a charm.
Cassidy Stauffer says
Oh awesome, I'm glad you liked it! ...thanks so much for letting me know!!!

Laura M says
I think you mean vegetable broth...in order to qualify as vegan?
Cassidy says
I did!! Thanks for pointing it out me, I'll fix it right away!

Laura Moya says
Could I use heavy cream instead of the coconut milk? If so, would it be the same amount? Looks amazing!
Cassidy says
Even though I haven't tried it myself, I don't see any reason why you can't use heavy cream as a 1:1 substitute. I imagine it should work fine 🙂

This looks great! I've never had cream of mushroom soup. So happy to have a creamy vegan nourishing soup for these cold months ahead.
