Ingredients You’ll Need

You won’t need much to whip up a soul-soothing pot of Mushroom and Spinach Soup. Each ingredient plays a starring role, lending its unique character to create depth, color, and crave-worthy flavor in every bowl.

Mushrooms (8 oz, fresh cremini or button, sliced): For hearty texture and earthy flavor, mushrooms take center stage—be sure to use fresh for the best results.
Spinach (5 cups, fresh, washed): Tender spinach adds gorgeous green color and a gentle sweetness as it wilts into the broth.
Onion (1 medium, chopped): A savory base that enhances the soup’s complexity and balances the other flavors.
Garlic (2 cloves, minced): Garlic brings bold aroma and a punch of flavor, waking up your taste buds right from the start.
Vegetable broth (4 cups, low-sodium): The backbone of the soup—use a high-quality veggie broth for a rich, satisfying result you’ll love.
Olive oil (1 tbsp): Essential for sautéing and adding a subtle richness that ties everything together.
Salt and pepper (to taste): Seasoning is key—make sure to taste and adjust so every bite sings.

How to Make Mushroom and Spinach Soup

Step 1: Sauté the Aromatics

Begin by heating the olive oil in a large pot over medium heat. Once the oil shimmers, add the chopped onion and let it cook, stirring occasionally, until it turns translucent and oh-so-sweet—about five minutes. Toss in the minced garlic and let it sizzle just until fragrant, making sure not to let it brown, to keep that lovely mellow flavor.

Step 2: Cook the Mushrooms

Next, add your freshly sliced mushrooms. Give them a good stir in the aromatic onion and garlic base. Allow them to cook for 7 to 10 minutes, stirring every now and then so they brown beautifully and release their juices. This step is what gives Mushroom and Spinach Soup its signature deep, umami flavor and a satisfying, meaty texture.

Step 3: Add the Broth and Simmer

Pour in the vegetable broth, scraping up any flavorful bits from the bottom of the pot. Bring the soup to a gentle simmer—this is where the magic happens as the flavors begin to meld and the base becomes rich and inviting. Let it simmer for around 5 minutes so everything comes together in harmony.

Step 4: Wilt the Spinach

It’s time for the spinach to take a bow! Add all those gorgeous greens to the pot, stirring gently until the leaves are thoroughly wilted and vibrant, which should only take about 2 minutes. You’ll notice the soup take on a lusciously green hue, and the spinach adds a subtle freshness that lightens the broth.

Step 5: Season and Finish

Taste your Mushroom and Spinach Soup and adjust with salt and pepper as desired. Give the soup a final gentle simmer for just another minute to marry the flavors together. With that, you’re ready to serve up ladles of steaming, savory goodness to warm every soul at your table.

Garnishes

For a finishing flourish, drizzle your steaming bowl with a touch of good olive oil or dust with freshly grated parmesan for a savory hit. A sprinkle of cracked black pepper or a scattering of crisp croutons can also add lovely contrast. Let everyone around the table add their own final touches for a bit of interactive fun.

Side Dishes

Mushroom and Spinach Soup shines with rustic, crusty bread—especially when warm and slathered with butter. A simple salad of leafy greens and citrus vinaigrette makes a refreshing pairing. For a heartier meal, serve alongside a classic grilled cheese or a slice of savory quiche.

Creative Ways to Present

For a chic presentation, try serving your Mushroom and Spinach Soup in small mugs or shot glasses as an appetizer at your next gathering. For cozy nights in, ladle soup into sourdough bread bowls, or top with a puff pastry round for a dramatic, golden-topped effect. Don’t be afraid to play with presentation—it makes every bowl feel extra special.

Make Ahead and Storage

Storing Leftovers

If you find yourself with extra Mushroom and Spinach Soup, let it cool completely, then transfer to an airtight container and refrigerate. It will keep beautifully for up to four days, making it a fantastic option for meal prep or next-day lunches.

Freezing

Yes, this soup freezes wonderfully! Pour fully cooled soup into freezer-safe containers or resealable bags. Leave a little headspace for expansion, then freeze for up to three months. Thaw overnight in the fridge for the best texture and to preserve those bright, fresh flavors.

Reheating

To reheat, gently warm on the stovetop over low to medium heat, stirring occasionally until heated through. If your soup has thickened, add a splash more broth or water to loosen it. Avoid boiling, as that can make the spinach lose its vibrancy and delicate flavor.

FAQs

Can I use frozen spinach instead of fresh?

Absolutely! Swap in frozen spinach if that’s what you have on hand. Just defrost and squeeze out excess moisture before adding to avoid watering down your Mushroom and Spinach Soup.

What kind of mushrooms work best?

Cremini or button mushrooms are both fantastic choices. If you want a bolder, woodsy flavor, try using a mix of wild or shiitake mushrooms for a unique twist to your Mushroom and Spinach Soup.

How can I make this soup creamier?

To make your Mushroom and Spinach Soup creamy, stir in a splash of heavy cream or a swirl of coconut milk at the end. For a lighter option, blend a cup of the soup and stir it back in to add body without the dairy.

Is this soup vegan and gluten-free?

Yes! As written, Mushroom and Spinach Soup is naturally vegan and gluten-free. Just double-check your broth and garnishes to keep things perfectly plant-based and safe for gluten-sensitive folks.

Can I add other vegetables or grains?

Certainly! Feel free to toss in diced carrots, celery, or a handful of cooked grains like rice or barley for even more heartiness and texture in your Mushroom and Spinach Soup. Make it your own!

Final Thoughts

With its luscious broth, meaty mushrooms, and heaps of bright spinach, Mushroom and Spinach Soup is pure comfort in a bowl. I hope you’ll treat yourself (and perhaps a few lucky friends) to this easy recipe soon—there’s just something about it that makes even an ordinary day feel wonderfully special.
