Low-Fat Creamy Mushroom Soup

Yes — unsweetened oat milk is an excellent substitute and produces a slightly creamier, less neutral body than almond milk because its higher starch content thickens naturally during the simmer. Use the same 1:1 ratio. Avoid flavored or sweetened oat milks, which throw off the savory balance. Soy milk also works well at 1:1; coconut milk (full-fat) works but adds a distinct coconut note that competes with the cremini and thyme.

Yes, with caveats. The almond milk base freezes reasonably well — better than a dairy cream soup, which typically breaks on thaw. Cool completely, store in freezer-safe containers for up to 2 months, and thaw overnight in the refrigerator rather than on the counter. Reheat gently over medium-low heat, whisking occasionally; if the texture looks slightly grainy after thawing, a 30-second blitz with an immersion blender restores the smooth body. Avoid refreezing.

The comparison is between this recipe (roughly 8 g fat per serving, calculated from USDA FoodData Central standard entries for cremini mushrooms, vegetable broth, and unsweetened almond milk) and a typical serving of Campbell's condensed cream of mushroom soup prepared as directed (approximately 28 g fat per equivalent serving per the USDA FoodData Central condensed-cream-of-mushroom entry). (28 − 8) ÷ 28 ≈ 71%. Both figures are approximate and reflect standard ingredient composition; individual nutrition may vary by brand and portion size.

This recipe is naturally gluten-free as written — no flour or roux is used for thickening; the creamy body comes entirely from the reduced mushroom juices and almond milk. The only potential gluten source is the broth: verify your vegetable or chicken broth is labeled gluten-free (some use maltodextrin or caramel color from barley). Everything else in the recipe — cremini mushrooms, almond milk, olive oil, onion, garlic, thyme — contains no gluten.

Total time is about 45 minutes (10 min prep + 35 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep olive oil from drying out.

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

Yes — this recipe is tagged low fat, vegetarian based on its ingredient list. Always cross-check labels for packaged ingredients (sauces, broths, condiments) since formulations vary by brand.
