There’s something deeply satisfying about the sizzle of mushrooms hitting a hot pan. That initial sear unlocks an earthy, savory depth that transforms simple ingredients into something special. As a chef, I’ve found this combination of mushrooms and spinach to be one of the most reliable, quick, and flavorful side dishes in my repertoire.
It’s the perfect answer to “what vegetable should I make?” on a busy weeknight, yet it’s elegant enough for a dinner party. You’ll be amazed at how a few basic techniques—like proper browning and deglazing—can create a side dish that tastes like it came from a professional kitchen, all in about 15 minutes.
- One-pan convenience: Everything cooks in a single skillet, meaning less cleanup and more flavor built right into the pan.
- Big flavor, fast: The technique of searing mushrooms and deglazing the pan creates a complex, umami-rich sauce in minutes.
- Diet-flexible: Naturally vegetarian and easily made gluten-free or vegan with simple swaps, fitting many dietary needs.
- Meal prep friendly: This dish reheats beautifully and can be the base for grain bowls, omelets, or pasta throughout the week.
- Endlessly versatile: Serve it as a simple side, toss it with pasta, pile it on toast, or use it as a gourmet burger topping.
- Nutrient-packed: You’re getting a powerful dose of vitamins, minerals, and antioxidants from two superfood vegetables.
Ingredients You’ll Need
Let’s gather our ingredients—this is where simple pantry staples come together to create something greater than the sum of its parts. The magic lies in the quality and treatment of the mushrooms. I highly recommend cremini mushrooms (also called baby bellas) for their robust flavor and meaty texture that holds up beautifully to high-heat cooking.
Their darker gills also give the final dish a richer color. For the fat, we’re using a combination of butter for flavor and olive oil for a higher smoke point, which allows us to get that perfect sear without burning. The dry white wine isn’t just for chefs; it adds a subtle acidity that brightens the dish, but a good broth works just as well.
The soy sauce is my secret weapon—it doesn’t make the dish taste Asian, but it adds a deep, savory backbone that enhances the mushrooms’ natural umami. Finally, using fresh baby spinach means it wilts in seconds without any tough stems.
[INGREDIENTIMAGEPLACEHOLDER]Kitchen Equipment Needed
You don’t need any fancy gadgets for this recipe. A large skillet (12-inch is ideal) is the most important tool. You need the surface area so the mushrooms can brown properly instead of steaming in a crowded pan.
A wooden spoon or spatula is perfect for stirring and scraping up the flavorful browned bits. A good chef’s knife makes quick work of slicing the mushrooms evenly, which is key for consistent cooking. That’s truly it.
While not essential, a pair of tongs is helpful for gently tossing the spinach at the end.
How to Make Sautéed Mushrooms with Spinach Recipe
Step 1: Prep Your Ingredients
This is a fast-moving recipe, so having everything measured and ready—your mise en place—is crucial. Wipe the mushrooms clean with a damp paper towel; rinsing them under water makes them soggy and they won’t brown properly. Slice them evenly, about a quarter-inch thick.
Mince the garlic and have your wine and soy sauce measured. This upfront work makes the cooking process smooth and stress-free.
Step 2: Sear the Mushrooms
Heat your large skillet over medium-high heat. Add the butter and olive oil. Wait until the butter’s foam subsides, then add the mushrooms in a single layer.
Here’s the pro tip: don’t touch them! Let them sit undisturbed for a good 2-3 minutes to develop a deep, golden-brown crust. This caramelization is the foundation of flavor.
Believe me, stirring them too soon will cause them to steam and turn gray.
Step 3: Build the Foundation
After that first good sear, you can stir the mushrooms. Continue cooking for another 4-5 minutes, stirring occasionally, until they are browned all over and have released their liquid. You’ll see the liquid evaporate and the sizzle will become louder.
Now, add the minced garlic and thyme. Stir constantly for just 30 seconds until incredibly fragrant—any longer and the garlic can burn and turn bitter.
Step 4: Deglaze for Maximum Flavor
Pour in the white wine or broth and the soy sauce. Immediately use your wooden spoon to scrape up all the delicious, dark browned bits stuck to the bottom of the pan. This process, called deglazing, dissolves those bits into the liquid, creating an instant, flavorful sauce.
Let it bubble and reduce by about half, which concentrates the flavor and cooks off the alcohol if using wine.
Step 5: Wilt the Spinach and Serve
Reduce the heat to medium-low. Swirl in the final tablespoon of butter to make the sauce glossy and rich. Now, add all the fresh spinach.
It will look like a lot, but it wilts down dramatically. Using tongs, gently toss and fold the spinach with the hot mushrooms and sauce. In just 1-2 minutes, it will be perfectly wilted but still vibrant.
Taste and season with pepper and salt only if needed.
- Dry is key: Always wipe mushrooms clean instead of washing them. They are porous and will absorb water, which then steams out in the pan and prevents proper browning.
- Don’t crowd the pan: If your skillet is smaller than 12 inches, cook the mushrooms in two batches. Overcrowding creates steam, which is the enemy of a good sear.
- Deglaze thoroughly: Those browned bits (fond) are pure flavor. Take the extra 30 seconds to scrape every last bit off the pan when you add your liquid.
- Timing for spinach: Add the spinach off the heat if you prefer it with more texture. The residual heat will wilt it gently. For fully wilted spinach, the minute or two over low heat is perfect.
- Acid balance: If you don’t use wine, a small squeeze of fresh lemon juice added at the very end can provide the necessary brightness to balance the rich, savory flavors.
Recipe Variations
- Creamy Mushrooms & Spinach: After deglazing, stir in 1/4 cup of heavy cream, crème fraîche, or full-fat coconut milk and let it simmer for 2 minutes before adding the spinach.
- Garlic & Herb Bomb: Increase the garlic to 5 cloves and add 2 tablespoons of chopped fresh herbs like parsley, chives, and tarragon with the spinach.
- Spicy Kick: Add 1/2 teaspoon of red pepper flakes or a few slices of fresh jalapeño with the garlic for a pleasant heat.
- Vegan Version: Substitute the butter with vegan butter or all olive oil, and use vegetable broth instead of wine if preferred. The soy sauce already provides plenty of savory depth.
- With Protein: Turn this into a main dish by adding a can of drained white beans or chickpeas when you add the spinach, or top it with a fried or poached egg.
- Italian Twist: Use balsamic vinegar instead of wine for deglazing, and finish with a sprinkle of grated Parmesan cheese.
What to Serve With This Recipe
This dish is the ultimate versatile side. For a classic pairing, serve it alongside pan-seared steak, roasted chicken, or grilled salmon—the savory mushrooms complement rich proteins perfectly. It’s also fantastic spooned over creamy polenta, mashed potatoes, or a bed of risotto, where the sauce adds incredible moisture and flavor.
To make it a complete vegetarian meal, toss it with whole wheat pasta or farro and an extra drizzle of olive oil. For a lighter option, it makes a wonderful warm salad topping. A crisp, dry white wine like Sauvignon Blanc or a light Pinot Noir pairs beautifully.
Storage & Make-Ahead Instructions
- Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 4 days. The flavors actually meld and deepen overnight.
- Reheating: Reheat gently in a skillet over medium-low heat with a tiny splash of water or broth to refresh the sauce. Avoid the microwave, as it can make the spinach slimy and the mushrooms rubbery.
- Freezing: I do not recommend freezing this dish, as both mushrooms and spinach become very watery and lose their texture upon thawing.
- Make-Ahead: You can fully cook the mushrooms with the sauce (through Step 4) up to 2 days in advance. Store the mixture in the fridge, then gently reheat it in a pan and wilt the fresh spinach just before serving for the best texture.
Frequently Asked Questions
Q: Can I use frozen spinach instead of fresh?
A: Yes, but thaw and thoroughly squeeze out ALL excess liquid from the frozen spinach first. If you add it with its water, it will make your dish soupy. Add it at the same time as you would fresh.
Q: Why are my mushrooms steaming and not browning?
A: This is almost always due to one of two issues: the pan was too crowded, or the heat wasn’t high enough. Ensure your mushrooms are in a single layer with space between them and that your pan is properly preheated.
Q: What’s the best substitute for white wine?
A: An equal amount of chicken or vegetable broth works perfectly. For a different flavor profile, you can use a tablespoon of balsamic vinegar or even fresh lemon juice.
Q: Can I make this without soy sauce for a soy-free diet?
A: Absolutely. Substitute with coconut aminos or simply use an extra pinch of salt. You’ll lose some umami depth, so you could add a teaspoon of tomato paste with the garlic to compensate.
Q: How do I know when the mushrooms are done cooking?
A: They should be a deep, golden brown all over, have significantly shrunk in size, and any liquid they released should have evaporated from the pan, leaving them sizzling in the fat.
Q: Is it okay to use pre-sliced mushrooms from the store?
A: You can, but I find they are often sliced too thinly and can become overcooked and rubbery. If you use them, reduce the initial searing time by a minute or two.
Q: My sauce tastes a bit flat. How can I fix it?
A: A flat taste often needs either salt, acid, or fat. First, ensure it’s properly seasoned with salt and pepper. A small squeeze of fresh lemon juice at the end can work wonders to brighten all the flavors.

Easy Sautéed Mushrooms with Spinach
Equipment
- Large skillet or sauté pan (12-inch is ideal)
- Wooden spoon or spatula
- Chef’s knife and cutting board
- Measuring spoons
Ingredients
- 1 lb Cremini or Baby Bella Mushrooms Wiped clean and sliced 1/4-inch thick
- 5 oz Fresh Baby Spinach About 5 packed cups
- 3 tbsp Unsalted Butter Divided
- 1 tbsp Olive Oil
- 3 cloves Garlic Minced
- 1/4 cup Dry White Wine or Broth Sauvignon Blanc or chicken/vegetable broth
- 1 tbsp Soy Sauce or Tamari
- 1 tsp Fresh Thyme Leaves Or 1/4 tsp dried thyme
- 1/4 tsp Black Pepper Freshly ground
- To taste Kosher Salt
- For garnish Fresh Parsley Chopped
Instructions
- Prepare the mushrooms by wiping them clean with a damp paper towel—never rinse them, as they absorb water like a sponge. Slice them into even 1/4-inch thick pieces. This ensures they cook uniformly. Mince the garlic and measure out your wine and soy sauce so everything is ready to go.
- Heat a large skillet or sauté pan over medium-high heat. Add 2 tablespoons of butter and the olive oil. Once the butter has melted and the foam subsides, add the mushrooms in a single layer. Do not stir for 2-3 minutes to allow a deep, golden-brown sear to develop—this is where the flavor builds. Trust me, this patience pays off.
- After the first side is browned, stir the mushrooms and continue cooking for another 4-5 minutes, stirring occasionally, until they are deeply browned all over and have released their liquid. You should hear a good sizzle. Add the minced garlic and fresh thyme, cooking for just 30 seconds until fragrant.
- Pour in the white wine (or broth) and soy sauce. Use a wooden spoon to scrape up all the delicious browned bits from the bottom of the pan—this is called deglazing and it adds incredible depth. Let the liquid bubble and reduce by half, about 1-2 minutes.
- Reduce the heat to medium-low. Add the remaining 1 tablespoon of butter and swirl it into the sauce until glossy. Now, add all the fresh spinach. Using tongs, gently toss and fold the spinach with the hot mushrooms. It will wilt dramatically in just 1-2 minutes. Season with black pepper and taste before adding salt, as the soy sauce is already salty.
- Transfer to a serving dish immediately. Garnish with chopped fresh parsley for a pop of color and freshness. Serve hot alongside your favorite protein or over creamy polenta. Step back and admire your perfectly cooked, restaurant-quality side dish.
