Soups & Stews
This brown rice and cream of mushroom soup recipe delivers a comforting, hearty meal where velvety soup meets perfectly cooked rice in every bite. The secret lies in cooking the rice separately—stovetop or rice cooker—while building the soup from scratch with sautéed mushrooms and rich cream for depth.
No shortcuts here; just restaurant-quality texture and flavor that feel like a warm hug on a chilly evening.
The soup starts with earthy mushrooms caramelized in butter, then blended into a smooth, creamy base using broth and cream. Meanwhile, the brown rice cooks up nutty and tender, absorbing just enough flavor from the soup to tie the dish together.
Serve them side by side or let the rice soak up the last spoonfuls of soup—either way, it’s a meal that’s equal parts satisfying and simple to prepare.
Ingredients for brown rice and cream of mushroom soup
Rich, earthy mushrooms and nutty brown rice create a comforting, restaurant-style meal.
| Ingredient | Amount | Notes |
|---|---|---|
| Brown Rice 🌾 | 1 cup | Uncooked, long-grain preferred |
| White Button Mushrooms 🍄 | 1 ½ lbs | Fresh, sliced into quarters |
| Unsalted Butter 🧈 | 4 tbsp | For caramelizing mushrooms |
| Shallots 🧅 | 2 whole | Minced, or sub 3 tbsp onion |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Vegetable Broth 💧 | 4 cups | Low-sodium preferred |
| Chicken Broth 💧 | 1 cup | For depth of flavor |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening soup |
| Fresh Thyme 🌿 | 1 tbsp | Leaves only, chopped |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated, for garnish |
The mushrooms are the soul of this dish—cremini or baby bella add more depth than white buttons, but those work fine too. Local farmers markets often have fresh, organic options at better prices than grocery stores. For the broth, Homemade is ideal, but Pacific Foods or Imagine brands are solid store-bought choices. The brown rice? Jasmine or long-grain cooks up fluffier than basmati, but any brown rice works. Rinse it well before cooking to remove excess starch.
No fresh thyme? Dried works at one-third the amount, but fresh gives that bright, herbal note. Running low on heavy cream? Full-fat coconut milk mimics the richness, though it tastes slightly different. The flour is just for thickening—arrowroot powder works too if you're gluten-free. For extra umami, add 1 tsp soy sauce or 1 tbsp nutritional yeast to the soup. And if you're short on time, pre-sliced mushrooms from the store save chopping minutes (just avoid the pre-cooked kind).
The rice keeps 4-5 days in the fridge, while the soup reheats beautifully—just stir in a splash of broth or water if it thickens. For make-ahead meals, cook the rice and soup separately, then refrigerate. Reheat the soup first, then warm the rice in a separate pot. Garnish with extra Parmesan and fresh thyme right before serving to keep everything vibrant. Portion into containers for 3-4 days of easy lunches.

Step-by-step instructions for brown rice and cream of mushroom soup
This method delivers a rich, velvety soup with perfectly cooked brown rice and deep mushroom flavor.
🍳 Step 1: Cook the Brown Rice Separately
Rinse the 1 cup brown rice thoroughly under cold water until the water runs clear. This removes excess starch that can make the soup gummy. In a medium saucepan, combine the rice with 2 cups water and bring to a boil over medium-high heat. Reduce heat to low and simmer uncovered for 40-45 minutes, stirring occasionally, until the rice is tender and the liquid is absorbed.
I like to press a grain between my fingers to check doneness—it should be soft but still hold its shape slightly. Once cooked, fluff the rice with a fork and set it aside. The rice will continue cooking slightly in the soup, so don't overcook it here. If you prefer firmer rice, reduce the simmering time to 35 minutes.
🍳 Step 2: Caramelize Mushrooms and Aromatics
In a large Dutch oven, melt the 4 tbsp unsalted butter over medium heat until it foams. Add the 1.5 lbs sliced white button mushrooms and cook for 8-10 minutes, stirring occasionally, until they release their moisture and begin to brown. This step develops deep umami flavor—don't rush it.
Add the 2 minced shallots and 4 minced garlic cloves, cooking for another 3-4 minutes until the shallots are translucent and the garlic is fragrant. Sprinkle the 1 tbsp all-purpose flour over the mushrooms and stir well to coat, cooking for 1 minute to remove the raw flour taste. This creates a natural thickener for the soup.
🍳 Step 3: Build the Velvety Mushroom Base
Pour in the 4 cups vegetable broth and 1 cup chicken broth, scraping up any browned bits from the bottom of the pot. Add the 1 tbsp chopped fresh thyme, 1 tsp salt, and 0.5 tsp black pepper. Bring to a gentle simmer over medium-low heat and cook for 15-20 minutes until the flavors meld and the soup reduces slightly.
Here's the thing—this simmering time allows the thyme to infuse properly and the mushrooms to develop their earthy depth. Taste the soup at this stage and adjust seasoning if needed. The broth should be well-seasoned but not salty, as we'll be adding the heavy cream next.
🥘 Step 4: Finish with Cream and Incorporate Rice
Reduce the heat to low and gradually whisk in the 1 cup heavy cream. Be careful not to let the soup come to a full boil, as this can cause the cream to curdle. Stir constantly for 2-3 minutes until the soup is smooth and creamy. The cream should blend completely without any lumps.
Gently fold in the cooked brown rice using a wooden spoon, mixing just until the rice is evenly distributed. The rice will absorb some of the soup, so we're adding it at the end to prevent it from becoming mushy. If the soup is too thick after adding the rice, thin it with a splash of warm broth. The final consistency should be creamy but still spoonable.
🍽️ Step 5: Garnish and Serve Warm
Ladle the soup into bowls and garnish each serving with 1 tablespoon freshly grated parmesan cheese. The parmesan adds a nice salty contrast to the creamy soup. Serve immediately while hot, as the flavors continue to develop together.
This soup pairs beautifully with crusty bread or a simple green salad. The brown rice adds a satisfying chewiness that balances the velvety texture of the cream of mushroom base. For extra richness, you can add a dollop of sour cream or extra parmesan on top before serving.
Pro Tips For Making Brown Rice And Cream Of Mushroom Soup
- Sauté Shallots Slow: I learned this the hard way—shallots caramelize fast, but if you rush them, they’ll turn bitter before the soup even simmers. Keep the heat at medium, stir every 30 seconds, and don’t walk away. You’re aiming for soft, translucent, not golden—save that for the mushrooms later.
- Toast Rice First: Skip the pre-cooked shortcut unless you’re in a hurry. Toast your brown rice in the same pot with butter for 2 minutes before adding liquid—it deepens the nutty flavor and prevents a gummy texture. (Yes, even if you’re impatient like me.)
- Slice Mushrooms Thin: Thick, uneven slices won’t break down into that creamy texture you want. Use a sharp knife and cut them paper-thin—almost like shaving. They’ll cook faster and blend smoother into the soup, making it velvety instead of chunky.
- Resist the Urge to Overcook: Brown rice needs 10–12 minutes after boiling, but cream of mushroom soup starts falling apart if you simmer it too long. Once the rice is tender, stir it into the soup just until heated through—no more. Overcooking turns the mushrooms mushy and the broth watery.
Essential equipment for brown rice and cream of mushroom soup
Dutch Oven Essentials
A large Dutch oven is my go-to for this recipe—it handles the high heat for caramelizing mushrooms while keeping the soup from boiling over. I use a Le Creuset 5.5-quart because its thick walls distribute heat evenly, preventing hot spots that can burn the mushrooms.
If you don’t have one, a heavy-bottomed stainless steel pot works too, just monitor the heat more closely. 🔥
Immersion Blender
For that ultra-smooth texture, an immersion blender is a game-changer. After simmering the mushrooms and broth, I blend right in the pot for 10-15 seconds to break down the mushrooms without losing any flavor. A Ninja BN601 is my top pick—it’s powerful enough to handle the job without splattering.
If you don’t have one, a regular blender works, but you’ll need to strain the soup afterward to remove any lumps.
Wooden Spoon
A long-handled wooden spoon is a must for stirring the soup without scratching the pot. I prefer Oxo Good Grips because the handle stays cool even after hours of use.
Wood also helps distribute heat more evenly than metal, preventing hot spots that can curdle the cream. Avoid plastic spoons—they can melt under high heat.
Fine-Mesh Strainer
If you’re blending the soup separately, a fine-mesh strainer ensures a silky-smooth result. I use a Mesh King Strainer to remove any mushroom bits or thyme stems that could make the texture gritty.
For extra insurance, line the strainer with a cheesecloth and press gently with a spoon to extract all the flavor. This step is especially important if you’re using dried thyme, which can leave behind tiny particles.
Measuring Cups and Spoons
Precision matters with this recipe, so invest in stainless steel measuring cups and spoons for accurate broth and cream ratios. I keep a set of OXO Good Grips in my kitchen—they’re durable and easy to read.
For the 1 cup heavy cream, use a liquid measuring cup to avoid overfilling. A splash too much can make the soup too rich, while too little leaves it thin and watery.
Cheese Grater
Freshly grated Parmesan cheese makes all the difference in the final garnish. A microplane grater gives you the finest, most flavorful shavings without the large, grainy bits. I love the Barbour Abrasive—it’s affordable and does the job perfectly.
For extra efficiency, grate the cheese right before serving so it stays fresh and aromatic. Pre-grated cheese loses flavor quickly and often contains anti-caking agents that dull the taste. 🧀
Nutrition facts
Frequently asked questions
Can I use instant brown rice for this recipe?
Instant brown rice works in a pinch, but it won't have the same nutty flavor or texture. The cooking time is much shorter (20-25 minutes), but you'll miss the depth that comes from simmering regular brown rice. If you're short on time, use 1.5 cups instant rice (which yields 3 cups cooked) and reduce the soup's liquid by 1 cup to compensate.
How do I fix curdled cream in my soup?
If your soup curdles, don't panic! Remove from heat immediately and whisk in 1-2 tablespoons of cold water to temper the cream. For a smoother fix, blend the soup with an immersion blender to break up any lumps. If the curdling is severe, strain the soup through a fine-mesh sieve to remove any separated cream, then whisk in 1 tablespoon cornstarch mixed with 2 tablespoons cold water to restore thickness.
Can I make this soup dairy-free?
Replace the 1 cup heavy cream with 1 cup full-fat coconut milk (canned, not carton) for a rich, creamy texture. For extra depth, add 2 tablespoons nutritional yeast when blending. The coconut milk will give a slightly tropical note, but it works beautifully with mushrooms. If you prefer a lighter option, use 1 cup cashew cream (blend 1 cup soaked cashews with 1 cup water until smooth).
Should I pre-cook the mushrooms before adding them to the soup?
No pre-cooking needed! The recipe relies on caramelizing the mushrooms to develop their rich, earthy flavor. Pre-cooking would make them mushy and watery, which would thin out your soup. The 8-10 minute sautéing time is crucial—it removes excess moisture and creates those beautiful browned bits (fond) that add incredible depth to the soup. Just slice them evenly so they cook uniformly.
How can I make this recipe gluten-free?
This recipe is naturally gluten-free except for the 1 tablespoon all-purpose flour. Replace it with 1 tablespoon gluten-free all-purpose flour blend or 1 tablespoon cornstarch. For extra insurance, check your broth labels—some contain wheat. If you're using gluten-free flour, you may need to simmer the soup for an additional 2-3 minutes to achieve the same thickness, as gluten-free flours thicken differently.
