Crock Pot Creamy Mushroom and Brie Soup Recipe

Ingredients
Ingredients:
- 2 tablespoons olive oil
- 1 1/2 pounds mushrooms, sliced (cremini or button preferred for best flavor)
- 2 tablespoons unsalted butter
- 1 yellow onion – thinly sliced, then halved
- 2 cloves fresh garlic, minced or finely chopped
- 1/3 teaspoon dried thyme (or 1 teaspoon fresh thyme leaves, chopped)
- 2 tablespoons all-purpose flour
- 1/2 cup dry white wine (such as Pinot Grigio or Sauvignon Blanc; substitute with more chicken broth for alcohol-free)
- 4 cups chicken broth (low sodium preferred, or vegetable broth for a vegetarian option)
- 4 ounces Brie cheese, cut into 1-inch pieces (ensure rind is completely removed for the smoothest texture)
- 1/2 cup heavy cream (or half-and-half for a slightly lighter soup)
- Salt & freshly ground black pepper to taste
Instructions
- Begin by preparing your mushrooms. Clean them gently with a damp cloth to remove any dirt, and then slice them evenly. Aim for consistent slices to ensure they cook uniformly and achieve optimal caramelization.
- In a large bowl, toss the sliced mushrooms with the olive oil until they are lightly and evenly coated. This step is crucial for achieving a beautiful golden-brown color and intensifying their flavor during roasting.
- Spread the oiled mushrooms in a single layer on a baking sheet. Roast them in a preheated oven at 400°F (200°C) for approximately 20 minutes, or until they are deeply caramelized and tender. Make sure to turn them once halfway through the cooking time to ensure even browning on all sides. Roasting truly brings out their intense umami flavor, a key element for this mushroom soup.
- While the mushrooms are roasting, melt the unsalted butter in a large skillet or pan over medium heat. Add the thinly sliced and halved yellow onion. Cook, stirring occasionally, until the onions are soft, translucent, and slightly golden, which should take about 5-7 minutes.
- Stir in the minced garlic and dried thyme. Continue to cook for another minute until the garlic is fragrant and slightly golden. Be careful not to burn the garlic, as it can turn bitter quickly.
- Sprinkle the all-purpose flour over the onion and garlic mixture. Cook for 2 minutes, stirring constantly. This step creates a roux, which will serve as the thickening agent for our soup and ensures there’s no raw flour taste.
- Once the roasted mushrooms and sautéed onions are ready, transfer them into your slow cooker. Pour in the dry white wine and chicken broth. Add the prepared Brie cheese pieces. Remember to remove the rind from the Brie for the smoothest, most luxurious soup texture.
- Cover the slow cooker and cook on the LOW setting for 6-10 hours, or on the HIGH setting for 4-6 hours. The longer cooking time on low generally allows the flavors to deepen and meld more thoroughly, resulting in a richer, more complex slow cooker mushroom and Brie soup.
- About 30 minutes before serving, or just before you’re ready to eat, stir in the heavy cream. This adds the final touch of creaminess without risking curdling from prolonged cooking. Season generously with salt and freshly ground black pepper to taste. Adjust as needed to bring out the best flavors.
- Ladle the warm, creamy soup into bowls. Garnish with fresh herbs, such as chopped parsley or chives, if desired, for a touch of freshness and color. Serve immediately and enjoy every heartwarming spoonful of this delectable slow cooker mushroom and Brie soup!
Ingredient Spotlight: Making Your Soup Shine
Each ingredient in this creamy mushroom and Brie soup plays a crucial role in building its incredible flavor and texture. Understanding these roles can help you customize and perfect your dish, transforming it into a truly unforgettable meal.
Mushrooms: The Umami Powerhouse
The foundation of this soup lies in its mushrooms. While common button mushrooms will work, using cremini (often labeled as baby bella mushrooms) offers a richer, meatier flavor profile that greatly enhances the soup’s depth. For an even more profound and complex taste, consider incorporating a mix of wild mushrooms like shiitake, oyster, or porcini. Roasting them beforehand isn’t just an extra step; it’s a culinary game-changer. This process caramelizes their natural sugars, intensifying their earthy flavor and developing that coveted umami taste that makes the soup so profoundly satisfying. Don’t skip this critical step for truly deep mushroom flavor!
Brie Cheese: The Secret to Silky Smoothness
Brie cheese is the star that transforms this into a truly decadent experience. Its mild, buttery, and slightly pungent flavor, combined with its incredible melting properties, contributes significantly to the soup’s velvety, luxurious texture. When adding Brie, it’s absolutely essential to remove the rind. While edible on its own, the rind doesn’t melt smoothly in a hot liquid and can leave a slightly grainy or chewy texture in the finished soup. Cutting the cheese into small, uniform pieces also helps it melt faster and incorporate more evenly into the hot broth, ensuring a consistently smooth and delightful spoonful every time.
Aromatics and Herbs: Building the Flavor Base
Yellow onions and fresh garlic are the unsung heroes of many great soups, providing a sweet and pungent aromatic base that lays the groundwork for complex flavors. Sautéing them until tender and fragrant unlocks their full flavor potential, releasing their essential oils and mellowing their sharpness. Thyme, with its subtly earthy and minty notes, pairs exceptionally well with the robust flavors of mushrooms and the richness of cheese, adding an aromatic depth without overpowering the other ingredients. You can also experiment with other complementary herbs like a sprig of fresh rosemary, a bay leaf, or even a hint of sage for different aromatic nuances that can elevate your mushroom brie soup.
White Wine & Broth: The Liquid Foundation
A dry white wine, such as Pinot Grigio or Sauvignon Blanc, adds a layer of acidity and sophisticated complexity that brightens the soup’s overall flavor profile. The alcohol cooks off during the sautéing and simmering process, leaving behind a delightful depth of flavor that is hard to replicate. If you prefer to avoid wine, an equal amount of good quality chicken or vegetable broth can be substituted, though you might miss that subtle, acidic lift that wine provides. Chicken broth provides a robust savory base, making it an excellent choice, but for a truly delicious vegetarian version, a high-quality vegetable broth works perfectly.
The Cream: The Finishing Touch
Heavy cream is the final ingredient that brings everything together, creating the signature rich and velvety texture of this creamy mushroom and Brie soup. Adding it at the end, just before serving, is crucial. This prevents the cream from curdling or breaking down during prolonged cooking, ensuring your soup remains perfectly smooth and luscious. For those looking for a slightly lighter option, half-and-half can be used as a substitute, though it will result in a less intensely rich final product.
Tips for Achieving the Perfect Creamy Mushroom & Brie Soup
Follow these expert tips to ensure your slow cooker mushroom and Brie soup turns out perfectly every time, cementing its place as a family favorite:
- Don’t Rush the Roast: As mentioned, caramelizing the mushrooms properly in the oven is non-negotiable for maximum flavor and umami development. It takes a little extra time, but it’s absolutely worth every minute for a truly standout homemade mushroom soup.
- Rind Removal is Key: For the smoothest, most luxurious soup, always take the time to meticulously trim the rind off your Brie cheese before adding it to the slow cooker. This prevents any gritty texture.
- Sauté Before Slow Cook: Pre-cooking the onions and garlic until tender and fragrant, and gently blooming the flour to create a roux, lays a strong flavor foundation that cannot be achieved by simply dumping raw ingredients into the pot. This initial step builds layers of flavor.
- Low and Slow for Best Flavor: While a high setting works in a pinch, cooking on low for a longer duration allows the flavors to truly develop and meld together, resulting in a richer, more harmonious, and deeply satisfying soup. Patience is a virtue in slow cooking!
- Season Thoughtfully: Add salt and pepper gradually and always taste the soup before serving. Remember that broths can vary in sodium content, and the Brie cheese also contributes a salty element. Adjust seasoning as needed for perfect balance.
- Cream at the End: Heavy cream is added at the very end of the cooking process to prevent it from curdling and to maintain its beautifully rich, smooth texture. Stir it in gently just before serving.
Creative Variations & Customizations for Your Soup
This creamy mushroom soup recipe is wonderfully versatile and can be easily adapted to suit your tastes or what you have on hand. Don’t be afraid to get creative!
- Vegetarian Delight: Easily transform this into a vegetarian soup by swapping the chicken broth for a rich, high-quality vegetable broth. The mushroom and Brie flavors are robust enough to stand on their own.
- Herb Boost: Enhance the herbaceous notes by adding a bay leaf to the slow cooker during the main cooking phase (remember to remove it before serving). A sprinkle of fresh parsley, chives, or even a few torn basil leaves before serving can add vibrant color and fresh aroma.
- Spice It Up: If you enjoy a little warmth or a subtle kick, a pinch of red pepper flakes added with the garlic and thyme can introduce a pleasant heat without overpowering the delicate flavors.
- Different Cheeses: While Brie is divine, you could experiment with other creamy, meltable cheeses. Gruyère offers a nutty, more intense flavor, while a touch of cream cheese can add extra tang and thickness. A blend of cheeses could also be interesting!
- Add Protein: For a heartier meal, consider adding cooked shredded chicken (rotisserie chicken works great!), sautéed slices of Italian sausage, or even crispy bacon bits during the last hour of cooking to infuse more flavor and substance.
- Gluten-Free Option: To make this soup gluten-free, substitute the all-purpose flour with a gluten-free all-purpose flour blend. Alternatively, you can use a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) added at the end with the cream to achieve the desired thickness.
Serving Your Delicious Mushroom & Brie Soup
This decadent slow cooker mushroom and Brie soup is fantastic on its own, but it truly shines when paired with the right accompaniments, making it a complete and satisfying meal:
- Crusty Bread: A warm, crusty baguette, a rustic artisan loaf, or a slice of flavorful sourdough bread is absolutely perfect for soaking up every last drop of the creamy, rich broth.
- Garlic Croutons: Homemade garlic croutons, toasted until golden and crispy, add a delightful crunch and an extra burst of aromatic flavor to each spoonful.
- Fresh Green Salad: A simple, lightly dressed green salad with a vinaigrette provides a refreshing and vibrant counterpoint to the richness and warmth of the soup, balancing the meal beautifully.
- Gourmet Grilled Cheese: For the ultimate comfort food pairing, serve this soup alongside a gourmet grilled cheese sandwich. The combination of cheesy soup and a gooey, grilled sandwich is simply irresistible.
- Roasted Vegetables: A side of tender roasted asparagus, broccoli florets, or green beans can add a lovely touch of greenery, additional nutrients, and a different texture to complement the smooth soup.
Storage and Reheating Instructions
Leftover creamy mushroom and Brie soup makes for an excellent lunch or quick dinner the next day. To store, allow the soup to cool completely before transferring it to an airtight container. It can be safely stored in the refrigerator for up to 3-4 days. When reheating, gently warm the soup on the stovetop over low to medium-low heat, stirring frequently, to prevent the cream from separating. Avoid boiling the soup aggressively. If the soup appears too thick or needs a refresh, you may need to add a splash of extra broth, milk, or cream to restore its original smooth and creamy consistency. This ensures your leftovers are just as delicious as the freshly made batch.
