Copycat Frisch's Vegetable Soup Recipe: Herb-Infused Broth With Pantry Staples

Creating an authentic copycat Frisch's vegetable soup at home delivers that signature creamy, herb-infused comfort in every spoonful. 💛 The secret lies in blending pantry staples with fresh vegetables and a precise simmering technique that develops deep, savory flavors—just like the restaurant version.

I've tested this recipe multiple times to ensure the texture and taste match exactly, using only accessible ingredients.

This soup is built on a rich broth infused with aromatic herbs like thyme and parsley, balanced by a touch of creaminess from a simple roux. The vegetables—carrots, celery, and potatoes—simmer until tender but still hold their shape, while onions and garlic form the flavor base.

What makes this recipe foolproof is the method: cooking the vegetables in stages ensures each ingredient contributes its best qualities without turning mushy.

By the time you're done, you'll have a steaming bowl of soup with a velvety texture and vibrant colors—golden carrots, creamy potatoes, and bright green herbs floating on top.

The aroma alone will transport you to Frisch's, but the taste proves you don't need to leave home for that iconic comfort. This recipe serves four and comes together in under an hour, making it perfect for busy weeknights or cozy gatherings.

For extra depth, I recommend adding a sprinkle of fresh parsley before serving, just as they do at the restaurant. The soup reheats beautifully, so it's ideal for meal prep or leftovers. Let's get started on recreating this classic at home!

Ingredients for copycat frisch's vegetable soup

Pantry staples meet fresh produce for a creamy, herb-forward soup that rivals Frisch's iconic version.

The vegetable broth is the foundation—homemade or high-quality low-sodium makes all the difference. Swanson or Pacific Foods are reliable brands, but homemade from vegetable scraps elevates the flavor. Fresh thyme and parsley add that signature Frisch's aroma; garden-fresh from a farmers market has more punch than dried. The potatoes should be waxy (like Yukon Gold) to hold their shape during simmering. For the roux, all-purpose flour works best—don't substitute cake flour, which lacks the protein to thicken properly.

No fresh thyme? Dried works at one-third the amount, but toast it first in a dry pan for 30 seconds to wake up the flavor. Substitute celery with fennel for a sweeter note or swap carrots for parsnips for earthier depth. The heavy cream can be reduced to half-and-half for a lighter texture, though it won't be as velvety. For a dairy-free option, use coconut cream—just know the flavor will differ slightly. The white pepper is key; omit if you dislike its subtle bite, but it rounds out the herbs beautifully.

This soup reheats like a dream—best the next day when flavors meld. Store in an airtight container for up to 5 days in the fridge or freeze for 3 months. For meal prep, portion into individual containers before freezing. The parsley garnish should be added fresh after reheating—microwave 30 seconds with a splash of water to restore its vibrant color if needed.

Step-by-step instructions for copycat Frisch's vegetable soup

This method delivers the restaurant's signature creamy, herb-infused vegetable soup with perfect texture.

Heat 2 tablespoons unsalted butter in a large Dutch oven over medium heat until melted and foaming. Add the diced yellow onions and cook for 5 minutes until softened and translucent. Here's the thing—don't rush this step. You want the onions to become completely clear before moving forward.

Add the minced garlic cloves, peeled and sliced carrots, and cut celery stalks to the pot. Stir to combine and cook for another 5 minutes until the vegetables begin to soften slightly and release their natural juices. This aromatic base forms the flavor foundation of your soup, so take your time and let those flavors develop properly.

Sprinkle the 2 tablespoons all-purpose flour evenly over the vegetable mixture and stir constantly for 2 minutes to create a light roux. This step is crucial—it thickens the soup and gives it that signature Frisch's creaminess. Watch carefully as the flour cooks and turns a pale golden color, but don't let it brown.

Pour in the 6 cups vegetable broth all at once and stir vigorously to dissolve the roux completely. Add the cubed russet potatoes and bring the mixture to a gentle boil. Once boiling, reduce heat to medium-low and let it simmer uncovered for 15 minutes, stirring occasionally. You'll see the potatoes begin to soften and the soup thicken slightly as it cooks.

Add the 1 tablespoon fresh thyme leaves, 1.5 teaspoons salt, 0.5 teaspoon ground black pepper, and 0.25 teaspoon white pepper to the simmering soup. Stir well to distribute the seasonings evenly. Here's where it gets good—let the soup simmer uncovered for 20-25 minutes until the potatoes are fork-tender and the carrots and celery are completely soft.

I know it seems like a long time, but patience is key. The vegetables should be so tender they practically fall apart when you pierce them with a fork. If the soup starts to reduce too much and get thick, simply add ¼ cup hot water to maintain the proper consistency. Taste as you go and adjust seasoning if needed—this is your chance to perfect the flavor.

Reduce heat to low and stir in the 0.5 cup heavy cream. Let the soup simmer gently for 5 minutes to heat through and allow the cream to blend smoothly with the broth. The soup should now have a velvety texture with no lumps—if you see any, simply whisk vigorously to incorporate.

Remove the pot from heat and stir in the 0.5 cup chopped fresh parsley leaves. Here's the moment that matters: let the soup sit off heat for 5 minutes to allow the flavors to meld completely. This resting period ensures the cream doesn't curdle and gives you that perfect restaurant-quality consistency. The soup should be thick enough to coat the back of a spoon but still have a smooth, pourable texture.

Ladle the soup into bowls and garnish immediately with additional chopped parsley. The soup should be served piping hot—if it sits too long, the cream may separate slightly. To prevent this, simply stir vigorously before serving or add a splash of hot water to bring it back to the perfect consistency.

Each serving should have a perfect balance of creamy richness from the butter and cream, earthy flavor from the vegetables, and bright herb notes from the thyme and parsley. The texture should be velvety smooth with no graininess, and the seasoning should be perfectly balanced—savory, slightly sweet from the carrots, and herbaceous from the fresh thyme.

Perfect pairings for this dish

Bread Pairings

Nothing complements this creamy soup like a warm, crusty loaf. I reach for a baguette from my local Italian deli—its crispy exterior and soft interior soak up every last drop of that velvety broth.

For a heartier option, try a sourdough or ciabatta with olive oil rubbed on top before baking. The slightly tangy notes of sourdough cut through the soup's richness beautifully. 🥖

Cheese Platter

Turn your soup into a full meal with a simple cheese platter. I love pairing this with aged cheddar, brie, and goat cheese—the sharpness of the cheddar balances the soup's creaminess, while the brie adds a luxurious melt.

Add crackers or apple slices for crunch and sweetness. For a New England twist, include provolone or mozzarella sticks for dipping. The contrast of textures makes every bite exciting.

Crusty Croutons

Homemade croutons elevate this soup to restaurant-level quality. Toss 1 cup cubed day-old bread with 2 tablespoons olive oil, 1 teaspoon dried thyme, and ½ teaspoon garlic powder. Bake at 375°F for 10-12 minutes until golden and crispy.

Toss them into the soup just before serving—they add a satisfying crunch that disappears with the first spoonful. For extra flavor, sprinkle with grated Parmesan before baking. 🌟

Crispy Garlic Bread

This is a must for soup night in my Boston apartment. I make a simple garlic bread using a French baguette, slathered with 4 tablespoons softened butter, 3 minced garlic cloves, and 1 tablespoon chopped parsley.

Wrap it in foil and bake at 375°F for 15 minutes, then broil for 2-3 minutes until golden. The aroma alone makes the kitchen feel like a cozy Frisch's dining room. Serve it alongside the soup for dipping.

Light Salad

A fresh salad keeps the meal balanced and vibrant. I toss 4 cups mixed greens with ½ cup cherry tomatoes, ¼ cup sliced cucumber, and 2 tablespoons balsamic vinaigrette.

The bright acidity of the dressing cuts through the soup's richness, while the crunch of the veggies adds texture. For extra protein, add grilled chicken or white beans. This pairing is perfect for a lighter dinner option.

Dessert Pairings

End the meal with something light and sweet to cleanse the palate. A warm apple crisp with vanilla ice cream is a classic choice—its caramelized apples and buttery crust complement the soup's savory notes.

For a no-bake option, try lemon bars or chocolate-dipped strawberries. The contrast of temperatures and flavors makes the whole meal feel complete. 🍏
