Ingredients for brio mushroom soup
Restaurant-quality depth starts with these 15 ingredients—simple but transformative.
| Ingredient | Amount | Notes |
|---|---|---|
| Brio Mushroom Soup Base 🍄 | 1 box | Standard 10.5 oz box |
| Fresh White Button Mushrooms 🍄 | 8 oz | Sliced into 1/4-inch pieces |
| Celery Stalks 🧅 | 2 whole | Large, trimmed and cut into 1-inch pieces |
| Yellow Onion 🧅 | 1 whole | Medium, diced |
| Garlic Cloves 🧄 | 3 cloves | Fresh, minced |
| Dry White Wine 🍷 | ¼ cup | Sauvignon Blanc or Pinot Grigio |
| Vegetable Broth 💧 | 1 ½ cups | Low-sodium preferred |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Or 1 tsp dried thyme |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for richness |
| Heavy Cream 🥛 | ¼ cup | Optional for extra richness |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Butter 🧈 | 1 tbsp | Unsalted, for crispy celery |
| Panko Breadcrumbs 🍞 | ¼ cup | For celery crowns |
| Parmesan Cheese 🧀 | 2 tbsp | Freshly grated, for garnish |
The Brio box is your flavor foundation, but fresh mushrooms and celery take it to the next level. Trader Joe's or Whole Foods carry excellent white button mushrooms—look for plump, firm ones with no sliminess. For celery, choose stalks with crisp, pale green tops and no brown spots. The white wine adds brightness, so grab a dry Sauvignon Blanc or Pinot Grigio—whatever's open in your fridge works too. Fresh thyme is ideal, but dried thyme (one-third the amount) gets you close if you're in a pinch.
No white wine? Substitute extra vegetable broth—just add an extra splash. For a richer version, swap the heavy cream for cashew cream (blend soaked cashews with water). The crispy celery crowns are non-negotiable for that restaurant touch—panko breadcrumbs give the best texture. If you can't find panko, regular breadcrumbs toasted in a dry pan work too. The Parmesan should be freshly grated—pre-grated cheese gets clumpy and ruins the presentation. For a vegetarian boost, add 1/2 cup cooked lentils to the soup base.
This soup reheats beautifully—3-4 days in the fridge, 3 months frozen. The crispy celery crowns stay crunchy for 2 days if stored in an airtight container. I always make a double batch of crowns—one for the current soup, one for next week's leftovers. For meal prep, portion the soup into containers and store the crowns separately. When reheating, add a splash of water or broth to restore creaminess.

Step-by-step instructions for Brio mushroom soup with crispy celery crowns
Transform simple ingredients into a rich, earthy soup with restaurant-worthy crispy celery crowns.
Sauté Aromatics and Develop the Base
Heat 2 tablespoons olive oil in a large pot over medium heat. Add the diced yellow onion and cook for 5 minutes until softened and translucent. Add the minced garlic cloves and cook for an additional 30 seconds until fragrant—don't let it brown or it'll turn bitter.
Stir in the 8 ounces sliced fresh white button mushrooms and cook for 6-8 minutes until they release their moisture and begin to brown. This step builds deep umami flavor that forms the soul of your soup. Season with 1 teaspoon salt and ½ teaspoon black pepper, then add the 1 tablespoon fresh thyme leaves. Let the thyme infuse for 1 minute before proceeding.
Deglaze and Build the Soup
Pour in the ¼ cup dry white wine and scrape up any browned bits from the bottom of the pot—this deglazing captures all the flavor you've built. Let the wine simmer for 2-3 minutes until reduced by half. Add the 1 box Brio mushroom soup base and stir until fully dissolved.
Pour in the 1½ cups vegetable broth and bring to a gentle simmer. Reduce heat to low and let the soup cook for 10 minutes to allow all the flavors to meld together. Taste and adjust seasoning—you might need a pinch more salt or pepper depending on your broth. Here's where the magic happens: the Brio base enhances the homemade aromatics rather than overpowering them.
Finish with Cream and Prepare Celery Crowns
Stir in the ¼ cup heavy cream (if using) and let the soup simmer for another 2 minutes—this adds luxurious richness without making the soup heavy. While the soup finishes, prepare the crispy celery crowns: Trim the 2 whole celery stalks by cutting off the leafy tops and the bottoms. Cut each stalk lengthwise into ¼-inch thick strips, then slice each strip into 1-inch pieces. Toss them with 1 tablespoon butter and ¼ cup panko breadcrumbs until evenly coated.
Assemble and Garnish
Return the soup to a gentle simmer and carefully spoon the celery crowns into the pot. Let them simmer for 3-4 minutes until golden brown and crispy—this is where you get that satisfying crunch. Remove the celery crowns with a slotted spoon and place them on a paper towel-lined plate to drain any excess moisture.
Ladle the soup into bowls and garnish each serving with 2 tablespoons freshly grated Parmesan cheese and the crispy celery crowns. The contrast between the velvety soup and the crispy celery is what makes this dish truly special. Serve immediately while the celery remains crisp and the soup maintains its perfect temperature.
Pro Tips For Making Brio Mushroom Soup
- Sauté the Aromatics Slow: Don’t rush the onion, celery, and garlic—they’re the flavor foundation. Cook them on medium-low heat for 5-6 minutes until the onion turns translucent and the celery softens, or you’ll end up with a bitter, overcooked base that fights the Brio powder instead of complementing it.
- Slice Mushrooms Thin and Even: If you chop them unevenly, some will turn to mush while others stay tough. Aim for ¼-inch slices, and don’t overcrowd the pan—cook in batches if needed. This ensures every bite has the same perfect texture, not a mix of rubbery and mushy.
- Bloom the Garlic Right: Add the minced garlic to the pot after the onions are soft, but before the Brio powder goes in. Let it sit for 30 seconds—just until it fragrant, not browned. Burnt garlic ruins the whole dish, and this step guarantees it won’t.
- Simmer, Don’t Boil: Once the Brio base hits the liquid, keep it at a gentle simmer, not a rolling boil. You’re not making pasta water—you want the flavors to meld, not evaporate. A low simmer for 10 minutes does the trick without skimping on depth.
Perfect pairings for this recipe
Crusty Bread Pairings
This soup shines with a warm, crusty baguette—its chewy texture soaks up every last drop of velvety broth. I love using Breads Bakery's Parisian baguette from Trader Joe's, toasted until golden with garlic butter (mix 2 tbsp softened butter with 1 minced garlic clove and ½ tsp salt).
For extra indulgence, split the bread open and stuff it with goat cheese and thinly sliced pear before serving. 🥖
Wine Pairings
A crisp Chardonnay with subtle oak notes complements the soup's creamy texture beautifully. I reach for La Crema Sonoma Coast Chardonnay—its citrus and mineral notes cut through the richness while enhancing the earthy mushrooms.
For something lighter, a dry Riesling (like Dr. Loosen Blue Slate) adds brightness that refreshes your palate between spoonfuls. Avoid heavy reds—they'll overpower the delicate flavors.
Cheese Boards
Turn your soup into a full meal by serving it alongside a simple cheese board. I arrange aged Gouda, creamy Brie, and sharp white cheddar with walnuts and dried apricots for contrast.
The nutty depth of the Gouda pairs perfectly with the umami mushrooms, while the Brie adds a luxurious creaminess. Add a drizzle of honey to balance the savory notes—trust me, it's a game-changer. 🧀
Herbed Yogurt Dip
For a lighter option, serve the crispy celery crowns with a tangy herbed yogurt dip. Mix ½ cup plain Greek yogurt with 1 tbsp chopped fresh dill, 1 tsp lemon zest, and ½ tsp salt.
The cool, creamy dip balances the soup's warmth while adding a refreshing contrast. It's especially great if you're serving the soup as a starter or for a vegetarian meal. 🥄
Roasted Garlic Soup
For a flavorful twist, serve this mushroom soup alongside a roasted garlic soup with Gruyère cheese swirls. The nutty, caramelized notes of the roasted garlic complement the earthy mushrooms beautifully.
I make mine by roasting 4 whole garlic heads at 400°F for 30 minutes, then blending the cloves with 4 cups vegetable broth and 2 tbsp heavy cream. The contrast of flavors takes your meal to the next level. 🌟
Coffee Pairing
Finish your meal with a rich dark roast coffee to cleanse your palate and enhance the soup's umami flavors. I recommend a medium-roast Ethiopian with its floral notes—it creates a perfect balance with the earthy mushrooms.
If you prefer tea, a Earl Grey with its bergamot aroma adds a sophisticated touch that pairs wonderfully with the crispy celery crowns. ☕

Frequently asked questions
Can I make this soup without white wine?
If you don't have white wine, substitute with ¼ cup extra vegetable broth or apple cider vinegar (just 1 tablespoon) for brightness. The wine adds depth, but the soup will still taste delicious. For a richer alternative, use ¼ cup chicken broth instead of vegetable broth.
How do I keep the celery crowns crispy?
Toast the panko breadcrumbs in a dry pan for 2 minutes before coating the celery to add extra crunch. Also, drain the celery crowns on paper towels after cooking to remove excess moisture. Serve them immediately—they lose crispness after 10-15 minutes sitting in the soup.
Can I make this vegetarian?
Yes! Skip the heavy cream and use ¼ cup cashew cream (blend ½ cup soaked cashews with ¼ cup water) for richness. Add ½ cup cooked lentils or crumbled tempeh for protein. The Brio base is already vegetarian-friendly, so no other changes are needed!
Why does my soup taste too salty?
The Brio base is highly concentrated, so taste before adding extra salt. If needed, dilute with ¼ cup extra broth or balance with acidity—stir in 1 teaspoon lemon juice or ½ teaspoon vinegar. The crispy celery crowns also help cut through saltiness when served together.
Can I freeze the soup?
Freeze the soup (without celery crowns) for up to 3 months in airtight containers. Reheat gently on the stove with a splash of broth to restore creaminess. The celery crowns don't freeze well—make fresh when serving. For best results, freeze the soup in portions and reheat only what you need.
