Deeply browned mushrooms, thyme, stock, and cream turned into a silky, restaurant-level cream of mushroom soup —
the same base we use for BiteTalk’s scratch green bean casserole, but good enough to serve straight in a bowl.

Cream of Mushroom Soup
A rich, deeply savory cream of mushroom that starts with real mushrooms, browned hard in butter and olive oil,
then finished with thyme, stock, cream, and a splash of soy or Worcestershire for that “what is that?” depth.
Serve as a soup or use as the base for BiteTalk’s green bean casserole.

Adjust “Target servings” on the front card to scale.
Mushroom Base
cremini or button mushrooms, finely chopped
unsalted butter
olive oil
1 small onion (or 2 shallots), minced
3 garlic cloves, minced
all-purpose flour
Liquid & Flavor
chicken or vegetable stock
heavy cream or half-and-half
1 tsp fresh thyme leaves
(or ½ tsp dried thyme)
Pinch freshly grated nutmeg
(optional but excellent)
1–2 tsp soy sauce or Worcestershire
(for depth)
Salt & freshly ground black pepper, to taste
To Finish & Serve
Extra cream or stock to thin to your perfect soup consistency
Chopped fresh parsley or thyme, for garnish
Extra sautéed mushroom slices, for topping (optional)
Dairy: unsalted butter, heavy cream or half-and-half
Pantry: olive oil, all-purpose flour, soy sauce or Worcestershire, nutmeg, salt, black pepper
Stock: chicken or vegetable stock
Step-by-Step — Brown, Build, Blend
1.Prep your mushrooms and aromatics.
Clean the mushrooms with a damp towel (don’t soak them), then finely chop.
Mince the onion/shallots and garlic. Have your stock and cream measured and ready.
2.Brown the mushrooms hard.
In a large sauté pan, heat the butter and olive oil over medium-high.
Add the chopped mushrooms with a pinch of salt. Cook, stirring occasionally, until they release their liquid,
it cooks off, and they get deeply browned around the edges.
This is where the soup’s flavor comes from — don’t rush it.
3.Soften the aromatics.
Reduce the heat to medium. Add the minced onion/shallots and cook until softened, 3–4 minutes.
Add the garlic and thyme and cook 1 minute more, just until fragrant.
4.Build a roux.
Sprinkle the flour evenly over the mushroom mixture. Stir constantly for 1–2 minutes so the flour coats
everything and loses its raw taste. It should look a bit pasty and clingy around the mushrooms.
5.Add the stock slowly.
While whisking or stirring, slowly pour in the stock, smoothing out any lumps as you go.
Bring to a gentle simmer and cook a few minutes until slightly thickened.
6.Finish with cream.
Pour in the cream and bring the soup back to a low simmer. Add the nutmeg (if using) and a small splash
of soy sauce or Worcestershire. Taste and adjust with more soy/Worcestershire until it hits that “supercharged
cream of mushroom” level.
7.Blend (optional) and adjust texture.
For a rustic soup, leave it as-is with little mushroom pieces. For a silkier version, blend part or all of
the soup with a blender or immersion blender, then return to the pot. Thin with extra stock or cream until
it’s as thick or sippable as you like.
8.Final seasoning.
Taste and season with salt and plenty of black pepper.
You want it to taste slightly more intense than a standalone soup if you’re planning to use it as a casserole base.
9.Serve or use as a base.
Ladle into bowls, garnish with herbs and extra sautéed mushrooms, and serve with crusty bread.
Or fold in blanched green beans and bake as the sauce in
BiteTalk’s green bean casserole, topped with
homemade fried onions.
BiteTalk Boost
Color = flavor. Don’t stop cooking the mushrooms when they’re just soft — keep going until they’re deep golden-brown in spots for that steakhouse-level mushroom flavor.
Salt in stages. Add a pinch when browning mushrooms, then season again after adding stock and cream so you don’t accidentally oversalt at the end.
Make it casserole-strong. If you’re using this as a base for green bean casserole, let it be a little thicker and more aggressively seasoned — the veggies and baked time will mellow it out.
Store & Reheat
Cool the soup to room temp, then store in airtight containers in the fridge for up to 3–4 days.
Reheat gently over low heat, thinning with a splash of stock or cream if it thickens.
For the best texture, avoid boiling hard once the cream is in. This base also freezes well for 1–2 months
— thaw in the fridge overnight and reheat low and slow.

Gear I Use for Cream of Mushroom
A wide pan for browning, steady heat, and a good ladle make building this soup (and your green bean casserole base)
way easier. Here’s the style of gear I reach for on BiteTalk.
Cookware
Heavy Sauté Pan or Saucepan
A wide, heavy-bottomed pan gives the mushrooms enough space to brown instead of steam, which is the key to big flavor.
