Ingredients

• Butter: Creates a rich base for sautéing the vegetables and adds a silky mouthfeel to the finished soup.
• Shallot: Provides a milder, more delicate flavor than onions. If unavailable, substitute with half a small yellow onion.
• Garlic: Adds essential aromatic depth. Fresh is best, but jarred minced garlic works in a pinch.
• Baby Bella Mushrooms: These brown mushrooms offer a deeper, more earthy flavor than white button mushrooms. They’re the star of this soup!
• Beef Broth: Forms the savory base of the soup. For a vegetarian version, use vegetable broth instead.
• White Wine: Adds brightness and acidity that balances the richness. Use a dry white wine like Sauvignon Blanc or Pinot Grigio.
• Worcestershire Sauce: Provides a umami boost and depth that ties all the flavors together.
• Dried Herbs: Dill, thyme, and paprika create a balanced herb profile that complements the mushrooms perfectly.
• Pearl Couscous: These small, pearl-shaped pasta balls add wonderful texture. Also called Israeli couscous.
• Half and Half: Creates the creamy finish without making the soup too heavy. For a lighter version, use whole milk.
• Sour Cream: Used as a garnish that adds tanginess and extra creaminess when swirled in.
• Crusty Bread: Essential for serving alongside to soak up every last drop of the delicious broth.

Variations

Vegetarian Version

Replace the beef broth with vegetable broth and ensure your Worcestershire sauce is vegetarian (traditional versions contain anchovies). Add a tablespoon of nutritional yeast for extra umami flavor to compensate for the beef broth.

Dairy-Free Adaptation

Substitute the butter with olive oil, and replace the half and half with unsweetened coconut cream or your favorite plant-based cooking cream. Skip the sour cream garnish or use a dairy-free alternative.

Protein-Packed Version

Add 1-2 cups of shredded rotisserie chicken or bite-sized pieces of cooked Italian sausage during the last 5 minutes of cooking for a heartier meal. This transforms the soup into a complete one-pot dinner.

Wild Mushroom Luxury

Elevate this soup by using a mix of wild mushrooms like shiitake, oyster, and chanterelle instead of only baby bellas. The variety of mushrooms creates a more complex and nuanced flavor profile that mushroom lovers will appreciate.

How to Make the Recipe

Step 1: Sauté the Aromatics and Mushrooms

Melt butter in a large pot over medium heat, being careful not to let it brown. Add the sliced baby bella mushrooms, minced shallot, and minced garlic to the pot. Cook for 2 minutes, stirring frequently, until the mixture becomes fragrant and the mushrooms begin to release their moisture.

Step 2: Build the Flavor Base

Sprinkle the dried dill, thyme, and paprika over the mushroom mixture and stir to coat evenly. This helps bloom the dried herbs and wake up their flavors. Whisk in the Worcestershire sauce, white wine, and beef broth. Take a moment to taste and adjust the seasoning with salt and pepper.

Step 3: Cook the Couscous

Bring the soup to a boil, then add the pearl couscous. Cover the pot with a lid, reduce the heat to medium, and let the soup simmer for about 20 minutes. The pearl couscous will absorb some of the flavorful broth as it cooks, expanding and becoming tender.

Step 4: Finish and Serve

Check that the couscous is cooked to al dente – it should be soft but still have a pleasant chew. If needed, simmer for a few more minutes. Remove the pot from heat and stir in the half and half, incorporating it fully into the broth. Ladle the soup into bowls, top with a dollop of sour cream, and serve with crusty bread on the side.

Tips for Making the Recipe

• Don’t rush the mushroom cooking process – allowing them to release their moisture is key to developing deep flavor
• Use room temperature half and half to prevent it from curdling when added to the hot soup
• For extra flavor, deglaze the pot with the white wine after sautéing the vegetables, then add the broth
• If you prefer a thicker soup, make a quick slurry with 1 tablespoon cornstarch mixed with 2 tablespoons cold water and add it before the couscous
• Fresh herbs can be substituted for dried – use 1½ teaspoons each of fresh dill and thyme instead
• For a stronger mushroom flavor, rehydrate a small handful of dried porcini mushrooms and add them along with their soaking liquid

How to Serve

This creamy mushroom soup is best served hot in wide, shallow bowls that allow the steam to rise and the aroma to be fully appreciated. A dollop of sour cream adds a tangy contrast when swirled into the soup. Serve with thick slices of crusty bread or artisan sourdough for dipping – essential for capturing every last bit of the flavorful broth.

For a complete meal, pair with a simple side salad dressed with lemon vinaigrette to provide a refreshing contrast to the rich soup. A glass of the same dry white wine used in the cooking makes an excellent accompaniment, creating a harmonious flavor experience.

Make Ahead

This soup is perfect for make-ahead meals and actually improves in flavor after sitting for a day. To prepare in advance:

For 1-2 days ahead: Complete the recipe through Step 3, but don’t add the half and half. Cool the soup completely, then refrigerate in an airtight container. When ready to serve, reheat gently on the stovetop, then stir in the half and half once hot.

For longer storage: Freeze the soup without the half and half for up to 3 months. The couscous may absorb more liquid upon thawing, so you might need to add a splash more broth when reheating. Add the half and half only after reheating.

The soup will thicken considerably when chilled as the couscous continues to absorb liquid. When reheating, you may need to add additional broth to reach your desired consistency.

FAQs

Can I use regular couscous instead of pearl couscous?

Regular couscous is much smaller and cooks faster than pearl couscous. If substituting, reduce the cooking time to about 5 minutes and be aware that the texture will be significantly different – more like tiny grains instead of pasta-like pearls.

How can I make this soup thicker?

For a thicker consistency, you can either increase the amount of pearl couscous by ¼ cup or create a slurry with 1 tablespoon cornstarch mixed with 2 tablespoons cold water. Add the slurry during the last 5 minutes of cooking the couscous and stir until thickened.

What can I substitute for white wine?

If you prefer not to use alcohol, substitute with an equal amount of additional beef broth plus 1 tablespoon of white wine vinegar or lemon juice to add brightness. Apple juice with a splash of vinegar can also work in a pinch.

Is there a way to make this soup more substantial for a main dish?

Absolutely! Add protein like shredded rotisserie chicken, sliced smoked sausage, or white beans. You could also stir in some baby spinach or kale in the last few minutes of cooking for added nutrients and color.
