Ingredients You’ll Need

These ingredients work harmoniously to create that perfect balance of buttery richness and tangy mustard punch. When shopping, choose fresh, firm green beans for the best texture and flavor.

• Fresh green beans: Look for bright green, snap-ready beans without blemishes or wrinkles.
• Coarse grain mustard: Adds texture and a robust flavor that really stands out.
• Dijon mustard: Provides a smooth and slightly spicy note, balancing the coarse mustard.
• Kosher salt: Enhances flavor without overpowering; adjust based on your salt preference.
• Black pepper: Freshly ground is best for that fragrant heat.
• Lemon juice: Brightens the sauce with fresh acidity—don’t skip it!
• Unsalted butter: Melted to bring creaminess; you can swap with olive oil if needed.

Variations

I love tweaking this recipe depending on what I have on hand or the mood we’re in. Feel free to make it your own! Sometimes I add little extras or switch out ingredients to match what’s fresh or to suit dietary needs.

• Make it vegan: I swapped the butter for good-quality olive oil once, and it was still delightful—with a lighter, bright flavor.
• Add garlic: For a garlicky twist, sauté minced garlic in the butter before tossing with the beans—I’ve done this when I wanted an extra savory touch.
• Use different mustards: Try all Dijon or spicy brown mustard if you don’t have coarse grain—each gives a unique flavor profile.
• Roasted green beans: Roasting instead of boiling gives a smoky edge, great for a fall twist.

How to Make Green Beans with Mustard Butter Sauce Recipe

Step 1: Blanch the Green Beans to Perfection

Start by bringing a large pot of salted water to a boil—seasoning the water is key since it’s your chance to add flavor from the get-go. Toss in the green beans and cook them until they’re crisp-tender, which usually takes about 5 minutes. If you like your beans softer, give them an extra 2 or 3 minutes. When they’re just right, drain them immediately to stop the cooking process—no mushy beans here!

Step 2: Whisk Together Your Mustard Butter Sauce

While the beans cook, grab a medium bowl and combine the coarse grain mustard, Dijon mustard, kosher salt, black pepper, lemon juice, and the melted butter. Give it a good whisk until everything’s blended into a creamy, zesty sauce. The lemon juice really brightens this up, so don’t skimp on it!

Step 3: Toss and Serve Immediately

Drain the green beans well, then add them straight into the bowl with your sauce. Toss gently but thoroughly so every bean is coated in that gorgeous mustard butter. Serve right away for the best texture and flavor. Trust me, you’ll want to dig in immediately!

Garnishes

I like to sprinkle some toasted sliced almonds or crispy shallots on top for crunch. A little extra lemon zest also brings a fresh burst of citrus aroma that elevates the dish. Don’t underestimate a sprinkle of finely chopped fresh parsley—it adds a pop of color and freshness.

Side Dishes

This green bean dish plays super well with grilled chicken or steak, but honestly, I’ve served it next to roasted salmon and creamy mashed potatoes for a dinner that’s impressive yet easy. It’s also a fantastic component at holiday meals, cutting through richer mains beautifully.

Creative Ways to Present

For dinner parties, I’ve arranged these green beans in a neat ring on a platter with lemon wedges fanned out alongside. Adding edible flowers or microgreens as a finish makes it really feel special. I also like serving them in individual ramekins for a cozy, elegant touch.

Make Ahead and Storage

Storing Leftovers

I store any leftovers in an airtight container in the fridge—green beans stay best when eaten within 2 days. Make sure to keep the sauce and beans together to keep the flavors melding.

Freezing

Freezing this dish isn’t my favorite because the texture of green beans changes, but if you must, freeze the beans and sauce separately, and thaw slowly in the fridge to preserve some texture.

Reheating

To reheat, gently warm the beans in a skillet over low heat just until heated through to avoid turning them mushy. Add a splash of water or a little extra melted butter if needed to refresh the sauce.
