Indulge in the ultimate comfort food with this incredibly creamy sweet potato mac and cheese! It’s not just a delight for your taste buds but also sneaks in a boost of nutrition thanks to the humble sweet potato. Perfect for any meal, this recipe also offers fantastic gluten-free and whole-grain options, making it a versatile crowd-pleaser.
My recent recipe creations have been a bit of a whirlwind, jumping from refreshing summer salads to cozy autumnal healthy cinnamon apple muffins, and then back to another seasonal summer dish. And now, as if on cue for a festive gathering, I’m sharing this incredible sweet potato mac and cheese recipe. You might wonder why such a hearty dish is appearing now, but there’s a charming reason behind it.
Growing up, summer vacations were synonymous with the simple joy of mac and cheese for lunch. It wasn’t a frequent treat, which perhaps made it even more special. For me, the comforting, cheesy goodness of mac and cheese holds a nostalgic and somewhat unusual connection to the warmth and leisure of summer days. This recipe perfectly blends that childhood nostalgia with a nutritious, modern twist.
Why Sweet Potato Mac and Cheese? A Healthier, Flavorful Upgrade
This sweet potato variation elevates traditional mac and cheese into something truly special. Incorporating sweet potatoes is one of my favorite ways to subtly enhance a dish, adding a touch of natural sweetness, vibrant color, and a significant nutritional boost. I’ve previously added them to unexpected places like these Paleo Chicken Meatballs or Healthy Muffins for Kids, always with delicious results. In this mac and cheese, the sweet potato not only contributes to an unbelievably creamy sauce but also introduces essential vitamins and fiber, transforming a classic comfort food into a more wholesome meal.
The first time I experimented with this easy mac and cheese recipe, I found myself short on the full amount of cheese. The outcome was surprisingly delightful – it had a distinct flavor reminiscent of Cheetos! While unexpectedly delicious, I decided to stick to the original plan for subsequent attempts. When I used the full quantity of cheese, it tasted exactly like classic mac and cheese, but with that wonderful underlying sweetness and depth from the sweet potato. If you’re looking for a more pronounced sweet potato flavor, don’t hesitate to increase the amount of puree.
Achieving the Perfect Creaminess: Blending vs. Mashing
The texture of your sweet potato puree plays a crucial role in the final consistency of your mac and cheese sauce. For a perfectly smooth, velvety sauce that’s indistinguishable from traditional mac and cheese (as seen in the initial photos), an immersion blender is your best friend. Alternatively, a small food processor or the nut butter jar attachment of a high-speed blender (like a Blendtec or Vitamix) works just as well. These tools break down the sweet potato completely, creating a seamless integration with the cheese sauce.
However, if you don’t mind a bit of texture and prefer a more rustic feel, simply mashing the cooked sweet potatoes with the bottom of a glass or a potato masher will yield a delightful, slightly chunkier sauce (as pictured below). Both methods result in a delicious dish, but if you’re serving this to particularly discerning eaters – be they picky kids or partners – the ultra-smooth texture achieved with a blender is often the preferred choice. It ensures the sweet potato blends seamlessly, offering all the nutritional benefits without any noticeable chunks.
No matter which method you choose, the resulting mac and cheese will be wonderfully flavorful. But for those aiming for a “hidden veggie” approach, blending is definitely the way to go for an unnoticeably nutritious meal.
The Great Cheddar Debate: Choosing Your Cheese Wisely
When it comes to cheese, I used 2 cups of regular orange cheddar for the photos at the top of this post. Interestingly, I often use a mix of 1 1/2 cups white cheddar and 1/2 cup Pecorino Romano, and that version still achieves a beautiful orange hue, as you can see in an older photo of this recipe below. For years, I exclusively used white cheddar under the assumption that all orange cheddar was artificially colored.
It turns out, while some cheddars are indeed artificially dyed, many achieve their vibrant color naturally using annatto seeds. Annatto is a natural food coloring derived from the seeds of the achiote tree. Despite this discovery, I still tend to gravitate towards white cheddar. I find that it offers the same rich flavor without any perceived difference, and I simply prefer its natural appearance. Feel free to experiment with your favorite cheddar or a blend of cheeses to find what you love most!
Customizing Your Sweet Potato Mac and Cheese
This sweet potato mac and cheese is truly spectacular on its own, offering a comforting and flavorful experience. However, it’s also incredibly versatile and easy to personalize with your favorite additions. I often enjoy it simply with a dash of garlic powder for an extra layer of savory depth. My husband, on the other hand, is a big fan of adding crispy bacon bits, which introduce a wonderful smoky, salty crunch that perfectly complements the creamy sauce.
Next time, I’m planning to incorporate some diced ham for a leaner protein option that adds a savory kick without the extra fat of bacon. Other fantastic additions could include sautéed mushrooms, caramelized onions, a sprinkle of fresh chives or parsley, or even a touch of smoked paprika for extra depth. You could also stir in some cooked broccoli florets or spinach for even more hidden veggies. Whatever you choose to add, this sweet potato mac and cheese serves as a delicious canvas for your culinary creativity!
Perfect Pairings and Serving Suggestions
What’s better than cheesy, carb-filled goodness? More cheesy, carb-filled goodness, or a delicious side to round out the meal! This sweet potato mac and cheese pairs beautifully with a variety of dishes. I’m already planning my next feast, where I’ll serve it alongside these delightful Gluten-free Cheddar Herb Muffins. The savory herbs and cheesy notes of the muffins would be a fantastic complement to the subtly sweet mac and cheese.
For those who love sweet potatoes as much as I do, this gluten-free sweet potato casserole looks like another incredible recipe to try. Imagine a table laden with both dishes – a true celebration of sweet potato versatility! And for a complete meal, consider adding a fresh green salad with a light vinaigrette to balance the richness. These gluten-free crescent rolls also look like a wonderful soft and buttery accompaniment to soak up every last bit of that creamy sauce. Whether served as a hearty side dish or a satisfying main, this sweet potato mac and cheese is sure to be a hit!
Frequently Asked Questions About This Recipe
What can I use instead of sweet potato?
If sweet potatoes aren’t available or you’d like to try a different flavor profile, pumpkin or butternut squash would make excellent substitutes. Both offer a similar creamy texture and a hint of sweetness. However, keep in mind that pumpkin and butternut squash tend to be a bit more watery than sweet potatoes. To avoid a thin sauce, you might want to reduce the amount slightly or, if using fresh squash, wring out some of the excess water with a tea towel after cooking and mashing. Alternatively, you could skip the guesswork and try my dedicated Pumpkin Mac and Cheese recipe!
Can I use a different type of pasta?
Absolutely! The beauty of mac and cheese is its adaptability. While elbow macaroni is a classic choice, feel free to use any pasta shape you prefer. Shells, penne, rotini, or even farfalle would work wonderfully to capture the rich, creamy sauce. For a gluten-free version, simply ensure you select a high-quality gluten-free pasta that holds up well to cooking.
Can I use something other than olive oil?
Yes, you can certainly substitute olive oil with other fats. Any neutral-flavored oil will work well. If you opt for coconut oil, I highly recommend using refined coconut oil to ensure there’s no lingering coconut taste in your mac and cheese. Butter is another excellent alternative that will add a rich, traditional flavor. If using butter, start with just a tiny bit more than 2 tablespoons to achieve a similar consistency to the oil-based roux, as butter has a slightly different fat content.
Do I have to use the flour?
Yes, the flour is a crucial component of this recipe as it forms the roux, which is essential for thickening the sauce. Without the flour, your sauce won’t emulsify and will likely result in a thin, soupy mixture rather than the rich, creamy consistency you’re looking for. For a gluten-free version, using a reliable 1-to-1 gluten-free baking flour (like Bob’s Red Mill 1-to-1 Gluten-Free Baking Flour) works perfectly to create a smooth and thick sauce.
Can I use a different type of cheese?
By all means! The cheese choice is very personal, and this recipe is flexible. Feel free to use whatever type of cheese you normally enjoy in your mac and cheese. Sharp cheddar, mild cheddar, Colby Jack, Monterey Jack, Gruyere, or even a blend of different cheeses would be delicious. As mentioned, I sometimes use a mix of white cheddar and Pecorino Romano for added depth. Just ensure it’s a cheese that melts well to create that signature gooey, comforting sauce.
Sweet Potato Mac and Cheese (gluten-free option)
Ingredients
- 1 medium sweet potato (mine was 370 grams and was a little more than what was needed)
- 2 cups (~250 grams) elbow macaroni if just mashing the sweet potato OR 3 cups (375 grams) if pureeing the sweet potato to make it totally smooth (for a gluten-free version, make sure to use GF macaroni)
- 2 tablespoons olive oil
- 2 tablespoons all-purpose flour or for a gluten-free version, use Bob’s Red Mill 1-to-1 Gluten-free Baking Flour
- 2 cups (475 ml) full-fat milk
- 1/2 teaspoon Dijon mustard (you can leave it out if you dislike it and add some garlic powder instead)
- 2 cups (225 grams) freshly grated cheddar or a mix of cheeses (I prefer 1 1/2 cups cheddar + 1/2 cup Pecorino Romano)
- 1/2 teaspoon salt
- 1/4 teaspoon freshly ground black pepper
Instructions
-
Bring a small pot of water to a boil. Meanwhile, peel and dice the sweet potato into 1/2″ pieces. Place in the boiling water and cook until tender, about 10-20 minutes. You can alternatively place the potato on a baking sheet and bake at 400 °F for 1 hour or until soft and then scrape out the flesh (you can really use any method at all to cook the sweet potato).
-
If you want a totally smooth sauce like in the photos, use an immersion blender to puree the sweet potato. A small food processor or a high-speed blender (using the smaller nut butter jar) would also work. If you don’t mind a little texture, you can mash the cooked sweet potato very well until no lumps remain. I used a flat-bottomed glass and it worked fine. Measure out 1 cup (245 grams).
-
Bring a medium pot of water to a boil and cook the macaroni according to the instructions on the package. Drain and set aside.
-
While the pasta is cooking, heat the olive oil in a large saucepan over medium-high heat. Add the flour and whisk for 1 minute. Slowly pour in the milk while whisking constantly. Cook until the mixture is thick enough to coat the back of a spoon, about 3-5 minutes.
-
Stir in the mustard, if using, cheese, and 1 cup of mashed / pureed sweet potato. If needed, cook another few minutes until thickened.
-
Add in the salt, pepper and then the macaroni. Stir until totally combined. Serve hot.
-
Let leftovers cool, cover and refrigerate to up to 5 days.
