Ingredients
- 2 medium sweet potatoes
Sweet potatoes are the star of this dish, providing a naturally sweet and slightly nutty flavor. They are also packed with nutrients like beta-carotene and fiber, making this dish not only delicious but healthy. - 4 tablespoons unsalted butter
Butter is essential for creating the brown butter sauce, which develops a rich and nutty flavor as it cooks. Unsalted allows for better control over the seasoning in the final dish. - 12 fresh sage leaves
Fresh sage adds an aromatic quality that complements the sweetness of the potatoes. It infuses the butter with its distinctive flavor, creating an earthy balance to the dish. - Salt to taste
Salt enhances the flavors of the ingredients and is crucial for bringing out the sweetness of the sweet potatoes. A pinch can make a significant difference in achieving a well-rounded taste. - Black pepper to taste
Freshly cracked black pepper adds a hint of spice to balance the sweetness of the dish. Its heat contrasts nicely with the rich brown butter and complements the earthy sage. - Grated Parmesan cheese (optional)
Parmesan adds a salty umami depth to the dish, enhancing the overall flavor profile. It's optional, but a sprinkle can elevate the richness of the brown butter sauce.
Directions & Preparation
Step 1: Spiralize the Sweet Potatoes
Begin by washing and peeling the sweet potatoes, then use a spiralizer to create noodles. This step is crucial as it transforms the sweet potatoes into the primary component of this dish. Ensure your noodles are uniform in thickness for even cooking.
Step 2: Cook the Sweet Potato Noodles
In a large pan, add a splash of water over medium heat and toss in the spiralized noodles. Cook for about 5-7 minutes, stirring occasionally until tender. This method preserves some of the noodles' natural sweetness and prevents them from becoming mushy. Keep an eye on them to ensure they cook just until al dente.
Step 3: Prepare the Sage Brown Butter
In a separate skillet, melt the unsalted butter over medium heat. Add the sage leaves once the butter starts foaming. This step is vital; swirling the pan as the butter cooks allows it to brown evenly, developing an incredible nutty flavor that will coat the noodles beautifully.
Step 4: Combine Noodles and Sauce
Once the butter has turned golden brown and has a delicious aroma, add the cooked sweet potato noodles to the skillet. Toss gently to coat the noodles in the sauce, allowing the flavors to meld together. This important step ensures every strand is infused with the rich brown butter and sage essence.
Step 5: Season and Serve
Season the dish with salt and freshly cracked black pepper to taste. If desired, finish with grated Parmesan for a creamy addition. Serving immediately preserves the warmth and texture of the noodles, showcasing the rich flavors that come together in this elegant dish.

Perfecting the Sage Brown Butter
Achieving the ideal sage brown butter requires attention and patience. As the butter melts, watch for a change in color, transitioning from yellow to a golden amber. The sage will crisp and infuse its flavor into the butter. It’s crucial to swirl the skillet to ensure even browning and to avoid burning, which can create a bitter taste.
Choosing Sweet Potatoes Wisely
When selecting sweet potatoes, aim for firm, unblemished ones without sprouts. Different varieties vary in sweetness and texture; orange-fleshed ones tend to be sweeter, while purple-mottled varieties may have a drier texture. Smaller potatoes are often sweeter and easier to spiralize, making for the best noodle experience.
Adding Variations to Your Dish
Customization is key to keeping this dish exciting. Consider adding sautéed mushrooms or spinach for extra nutrition and flavor. You could also spice it up with a hint of red pepper flakes or blend in some nuts for texture. This flexibility allows you to create a personalized meal tailored to your taste preferences.
FAQs
What if my sweet potato noodles become mushy?
To prevent mushy noodles, ensure you cook them only until al dente. Stirring occasionally while cooking helps maintain their structure, and soaking them in ice water before cooking can also keep them firmer.
How do I adjust the thickness of the sauce?
If your sauce is too thick, add a splash of pasta water or broth to loosen it. For a thicker sauce, allow it to simmer longer to reduce, or add a bit more butter to create a silkier texture.
Can I use dried sage instead of fresh?
Yes, you can substitute dried sage for fresh, but use it sparingly since dried herbs are more concentrated. Start with about a teaspoon and adjust to taste as it cooks, as it will infuse the butter quickly.
What types of sweet potatoes work best?
While orange-fleshed sweet potatoes are commonly used, Japanese or purple sweet potatoes can add a unique flavor and color. Just ensure they are firm and without blemishes for the best noodle experience.
Can I make this dish vegan-friendly?
To make this dish vegan, substitute the butter with a plant-based alternative and skip the Parmesan cheese. The nutty flavor of the browned vegan butter will still be delicious when paired with the sweet potatoes.
What should I do if my sauce lacks flavor?
If the sauce tastes bland, check your seasoning! Increasing the salt or mix in a splash of lemon juice can brighten the flavors significantly. Tasting as you go helps ensure the perfect balance.
Conclusion
Sweet potato noodles with sage brown butter sauce create a beautifully balanced dish that delights the palate. The combination of nature’s sweetness from the potatoes and the savory, nutty sauce exemplifies the magic of transforming simple ingredients into something extraordinary.
Whether served as a main course or a side dish, this recipe is sure to impress. So gather your ingredients, embrace the cooking process, and enjoy a hearty meal that celebrates the vibrant flavors of sweet potatoes.
