Whether you’re in the mood for a homemade cream of mushroom soup because you’re a mushroom soup fan or you’re looking to skip the canned varieties and make your own, this recipe is the perfect choice. Store-bought soup often contains many additives, and it’s hard to tell how long it’s been sitting on the shelf.

This soup is incredibly creamy and delicious, making it a great addition to your holiday dishes like green bean casserole, broccoli and cheese casserole, and other favorites.

What is Cream of Mushroom Soup?

Cream of mushroom soup is a smooth, creamy dish made from mushrooms, fats like butter, a bit of flour or another thickener, and milk or cream. It’s a velvety, rich preparation featuring earthy mushrooms, buttery fats, and wholesome milk or cream. While it’s delicious on its own, it’s often used as a comforting base for casseroles, sauces, and hearty home-cooked meals.

In many kitchens, cream of mushroom soup is a versatile pantry essential, adding richness, moisture, and extra flavor to dishes such as green bean casserole, broccoli and cheese casserole, and baked chicken. Making it from scratch provides a fresher taste, a better texture, and a more vibrant mushroom flavor than canned options.

Ingredeints

Mushrooms– Mushrooms are the star of the soup, providing an earthy, savory flavor and natural richness. Use white button, cremini (baby bella), or a mix of both. For a deeper flavor, you can add a few rehydrated dried mushrooms.

Butter– Butter adds richness and helps sauté the mushrooms, building the base flavor of the soup. Olive oil, avocado oil, or dairy-free butter can be used in place of butter.

onion– Onion adds depth and mild sweetness, balancing the earthiness of the mushrooms. Shallots or a small amount of onion powder (a pinch) can be used.

Garlic– Garlic enhances the savory flavor and adds warmth without overpowering the soup. (About 1/4 teaspoon of garlic powder can be used)

Flour- Flour thickens the soup and helps create the classic creamy texture.

Chicken broth: adds flavor and thins the soup to the right consistency without making it heavy. Vegetables are an option for a vegetarian, or homemade mushroom broth.

Milk- milk creates a smooth, creamy base without overpwoing the mushrooms. Half and half can be used for a richer soup, or unsweetned almound milk or oat milk for a diary free. (texture may be slighlty different if using dairy free)

Salt & Black Pepper: Salt and pepper are essential for seasoning and balancing flavors.

Directions

Step 1: Sauté the mushrooms

In a large saucepan or Dutch oven, melt the butter over medium heat. Add the sliced mushrooms and cook for 8–10 minutes, stirring occasionally, until they release their liquid and start to brown.

Step 2: Add onion and garlic

Stir in the diced onion and cook for 3–4 minutes until softened. Add the minced garlic and cook for 30 seconds (just until fragrant).

Step 3: Make the roux (thickener)

Sprinkle the flour over the mushroom mixture and stir well. Cook for 1–2 minutes, stirring constantly, so the flour cooks off and doesn’t taste raw.

Step 4: Add broth slowly

Pour in the chicken broth a little at a time, stirring as you go to keep it smooth and lump-free. Scrape up any browned bits from the bottom of the pot (that’s flavor).

Step 5: Simmer to thicken

Bring the soup to a gentle simmer and cook for 5–8 minutes, stirring occasionally, until it starts to thicken.

Slowly stir in the milk. Keep the heat on medium-low and let it warm through for 5–10 minutes, stirring often.

Step 7: Season to taste

Add salt and black pepper to taste. If you want extra flavor, you can add a pinch of thyme or a tiny splash of Worcestershire sauce (optional).

Step 9: Serve or use in recipes

Serve warm, or let it cool and use it as a base for casseroles like green bean casserole or broccoli and cheese casserole.

How to store Cream of Mushroom Soup

Refrigerator

Let the soup cool completely, then transfer it to an airtight container. Store in the refrigerator for up to 4 days. Stir well before reheating, as separation is normal.

Freezer

Homemade cream of mushroom soup freezes well. Once cooled, place it in freezer-safe containers or freezer bags, leaving room for expansion. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

Make Ahead for Holidays

This soup is perfect for holiday prep. You can make it 2–3 days in advance, store it in the refrigerator, and use it straight from the fridge when assembling dishes like green bean casserole or broccoli and cheese casserole. For longer prep, freeze it a few weeks ahead and thaw it the night before you need it.

Reheating

Reheat gently on the stovetop over medium-low heat, stirring often. If the soup thickens too much, add a splash of broth or milk to loosen it. Avoid boiling to keep the texture smooth.
