Side Dishes
Martha Stewart's green beans with Gruyère and mushrooms recipe transforms simple green beans into an elegant side dish with crispy cheese topping and creamy mushroom sauce. The secret lies in balancing earthy mushrooms, nutty Gruyère, and tender green beans—each component carefully timed for maximum flavor.
After perfecting this dish for countless dinner parties, I've refined the technique to ensure crispy cheese crust and velvety sauce every time.
This recipe begins with sautéing mushrooms until deeply flavorful, then simmering them in a light cream sauce until rich and aromatic. The green beans get a quick blanch to maintain their crisp-tender texture before being tossed in the mushroom mixture.
What sets this dish apart is the final step: pressing shredded Gruyère directly onto the top and broiling until golden and bubbly.
The result is a restaurant-quality side dish that's surprisingly simple to prepare in under 30 minutes. The mushrooms add depth, the Gruyère provides a satisfying crunch, and the green beans stay vibrant and tender.
This dish pairs beautifully with roasted meats or stands alone as a vegetarian centerpiece. The aroma alone will have everyone asking for seconds.
For best results, use fresh green beans and high-quality Gruyère—the cheese makes all the difference in achieving that perfect crispy topping. Garnish with fresh parsley or a sprinkle of breadcrumbs for added texture. Once you try this version, store-bought preparations will never compare again.
Ingredients for martha stewart green beans with gruyere and mushrooms
Earthy mushrooms, nutty Gruyère, and tender green beans—these ingredients elevate simple green beans into an elegant side dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Green Beans 🥦 | 1 ½ lb | Trimmed, ends removed |
| Gruyère Cheese 🧀 | ½ lb | Freshly shredded, aged variety |
| White Button Mushrooms 🍄 | 8 oz | Sliced into even thickness |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Unsalted Butter 🧈 | 2 tbsp | European-style preferred |
| Shallots 🧅 | 2 whole | Minced, or sub with onion |
| Garlic Cloves 🧄 | 2 cloves | Minced, fresh preferred |
| Dry White Wine 🍷 | ¼ cup | Sauvignon Blanc recommended |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | For seasoning |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Coarsely ground |
| All-Purpose Flour 🌾 | 1 tsp | For thickening sauce |
The Gruyère is non-negotiable here—look for aged wheels with visible holes and a rich, nutty aroma. Whole Foods or specialty cheese shops carry the best quality, but Costco sells pre-shredded if you're short on time. Fresh mushrooms are ideal, but pre-sliced from the store works fine—just pat them dry before cooking. For the green beans, harvest fresh or buy the thinnest variety available; thicker beans stay tough. The butter matters too—European-style has higher fat content, which prevents burning during the sauté. If you can't find it, unsalted works, but render it over low heat to remove moisture first.
No Gruyère? Comté cheese is the closest substitute, though it lacks the same melt. Short on mushrooms? Cremini mushrooms add deeper flavor, but white buttons work in a pinch. Wine missing? Chicken broth with a splash of lemon juice mimics the acidity. The flour is just for thickening—if you're avoiding gluten, cornstarch at half the amount works just as well. For the shallots, red onion in a pinch, but shallots add subtle sweetness. The parsley is purely decorative, but chives or tarragon add a nice twist if you're feeling adventurous. Always taste the sauce before adding cheese—adjust seasoning with salt and pepper.
This dish reheats beautifully—cover with foil and warm in a 350°F oven for 10 minutes. The Gruyère topping loses crispiness when reheated, so make it fresh if possible. Store leftovers in an airtight container for up to 3 days, but the cheese may soften. For make-ahead prep, assemble everything except the cheese, refrigerate, then broil before serving. The mushrooms and green beans can be blanched ahead and stored in ice water—drain and pat dry before using to prevent a soggy texture.

Step-by-step instructions for martha Stewart's green beans with Gruyère and mushrooms
This elegant dish delivers crispy Gruyère topping over a velvety mushroom sauce—simple yet sophisticated.
Blanch and Prepare the Green Beans
Trim the ends from the 1.5 lb of fresh green beans and cut them into 2-inch pieces. In a large pot, bring 4 quarts of salted water to a rolling boil—add 1 tablespoon of the diamond crystal kosher salt. Blanch the green beans for exactly 3 minutes until bright green and tender-crisp. Drain immediately and plunge into ice water to stop the cooking process. Drain again thoroughly and transfer to a serving platter.
This quick blanching preserves their vibrant color and crisp texture while ensuring they're perfectly cooked before adding the rich mushroom sauce. The ice bath shock stops the cooking instantly, preventing them from becoming mushy. Keep the beans warm while you prepare the sauce.
Sauté Shallots, Garlic, and Mushrooms
In a large skillet, melt the 2 tbsp of unsalted butter over medium heat until foaming. Add the 2 minced shallots and cook for 3 minutes until translucent. Stir in the 2 minced garlic cloves and cook for an additional 30 seconds until fragrant—you should smell the garlic's pungent aroma without any browning.
Add the 8 oz of sliced white button mushrooms and cook for 6-8 minutes, stirring occasionally, until they release their moisture and begin to brown at the edges. The mushrooms should be tender but still hold their shape. Season with the remaining 0.5 tsp of diamond crystal kosher salt and 0.25 tsp of freshly ground black pepper.
Deglaze and Build the Creamy Sauce
Pour in the 0.25 cup of dry white wine and scrape up any browned bits from the bottom of the pan with a wooden spoon. Let the wine simmer for 2-3 minutes until reduced by half. Sprinkle the 1 tsp of all-purpose flour over the mushrooms and stir to coat evenly, letting it cook for 1 minute to remove any raw flour taste.
Gradually whisk in the 0.5 cup of heavy cream, stirring constantly to prevent curdling. Simmer for 4-5 minutes until the sauce thickens enough to coat the back of a spoon. Taste and adjust seasoning with additional salt or pepper if needed. The sauce should be velvety and rich, with a perfect balance of wine acidity and creamy texture.
Assemble and Top with Gruyère
Spread the blanched green beans evenly on a serving platter. Spoon the creamy mushroom sauce over the green beans, distributing it evenly. Sprinkle the 0.25 cup of chopped fresh parsley over the top for freshness and color.
Using your hands, scatter the 0.5 lb of freshly shredded Gruyère cheese evenly over the green beans and sauce. The cheese should be distributed in an even layer, covering the entire surface. Place the platter under a broiler for 2-3 minutes until the Gruyère melts, bubbles, and turns golden brown in spots. Watch carefully to prevent burning.
Serve Immediately for Maximum Crispiness
Remove the platter from the broiler and let it rest for 1-2 minutes to allow the cheese to set slightly. The green beans should be warm, the sauce creamy, and the Gruyère crispy in spots with a golden hue. Serve immediately while the cheese is still slightly crispy and the sauce is at its peak temperature.
This dish is best served right away when the Gruyère is at its crispiest and the sauce is still warm and fluid. The combination of tender green beans, rich mushroom sauce, and crispy Gruyère creates a harmonious balance of textures and flavors that will impress any dinner guest.
Pro Tips For Making Martha Stewart Green Beans With Gruyere And Mushrooms
- Trim the Ends: Martha’s recipe works best with beans that snap cleanly—no fuzzy ends. I used to skip this, but those little fibers turn to mush and ruin the texture. Spend 2 minutes trimming the tough tips, and your dish will stay crisp where it counts.
- Sear Mushrooms First: Gruyère’s nutty flavor needs something to cling to, and raw mushrooms just melt into the cream. Sear them in butter for 5-6 minutes until golden—they’ll add depth and prevent a soggy finish. (Yes, even if the recipe says to add them later.)
- Don’t Overmix the Cream: Stirring the heavy cream in too hard turns it into a sauce, not a velvety coating. Gently fold it in at the end with a rubber spatula—just until combined. Overworking it makes the dish look (and taste) heavy.
- Use Cold Gruyère: Grated cheese from the fridge melts slower and coats the beans more evenly than warm cheese, which clumps. Take it straight out of the fridge, grate it, and toss it in while the pan’s still hot—it’ll stick like glue. (I learned this after a lumpy disaster.)
Make-ahead tips for this recipe
Prep Ahead Components
Start by blanching the green beans up to 2 days in advance. After blanching, immediately plunge them into ice water, drain well, and store in an airtight container in the refrigerator.
This preserves their vibrant color and crisp texture. I like to label the container with the date to track freshness. 🥦
Sauce Prep Strategy
Prepare the mushroom sauce separately and refrigerate it in a sealed container for up to 24 hours. When ready to serve, simply reheat the sauce gently in a saucepan over low heat until warmed through.
This method keeps the sauce creamy without breaking down the texture of the mushrooms. The wine reduction adds depth that develops overnight.
Cheese Pre-Shredding
Shred the Gruyère cheese ahead of time using a box grater or food processor. Store it in a resealable plastic bag in the refrigerator for up to 3 days.
Pre-shredding saves time during assembly and ensures even distribution. For best results, use freshly shredded cheese—pre-shredded store-bought varieties often contain anti-caking agents that prevent proper browning. 🧀
Broiler Prep Shortcut
Set your broiler to high heat and preheat it for 5 minutes before assembling the dish. This ensures the Gruyère melts and crisps immediately when you place the platter under the broiler.
I recommend using a broiler pan with a drip tray to catch any melted cheese. Position the oven rack 4-5 inches from the heat source for optimal browning.
Make-Ahead Assembly
For a complete make-ahead approach, assemble everything except the Gruyère cheese in a baking dish. Cover tightly with foil and refrigerate for up to 1 day. When ready to serve, sprinkle the cheese on top and broil as directed.
This method maintains the integrity of all components while allowing you to cook everything at once. The green beans will stay warm while the cheese crisps perfectly.
Reheating Leftovers
If you have leftovers, cover them with foil and reheat in a 350°F oven for 10-15 minutes. The Gruyère topping will soften but the dish will still be delicious. For a crispier texture, sprinkle additional shredded cheese on top and broil for 1-2 minutes before serving.
Store leftovers in an airtight container for up to 3 days in the refrigerator. 💫

Frequently asked questions
Can I use frozen green beans instead of fresh?
Fresh green beans work best for their crisp-tender texture, but frozen beans will work in a pinch. Thaw them completely first, then pat dry thoroughly before blanching. Add 30 seconds to your blanching time since frozen beans start partially cooked. For even better results, use high-quality frozen beans like Green Giant or Bird's Eye—avoid ice crystals or mushy varieties.
What's the best way to get crispy Gruyère without burning it?
Preheat your broiler for 5 minutes on high, then position the rack 4-5 inches from the heat source. Use a light hand when sprinkling cheese—too much creates a thick layer that burns before melting. For extra insurance, place the platter on a baking sheet to catch drips. Watch closely after 2 minutes and remove immediately when golden spots appear.
Can I make this dish vegetarian?
This recipe is already vegetarian-friendly as written. The earthy mushrooms and nutty Gruyère provide plenty of depth without any meat. For extra protein, serve with a side of roasted chickpeas or white beans. The dish pairs beautifully with vegetarian mains like stuffed bell peppers or portobello mushrooms.
Why did my sauce turn grainy?
Grainy sauce usually means the flour wasn't cooked long enough before adding cream. Always stir the flour into the mushrooms for 1 full minute to remove its raw taste. Also, avoid boiling the sauce—simmer gently over medium-low heat. If it thickens too much, whisk in 1 tablespoon of warm milk or broth to smooth it out.
How can I make this dish ahead of time?
Prepare the mushroom sauce up to 24 hours ahead and store it refrigerated. Blanch the green beans 2 days in advance and keep them in ice water until ready to use. Assemble everything except the cheese, refrigerate, then broil just before serving. This keeps all components fresh while saving you last-minute work.
