Side Dishes
This Trader Joe’s butternut squash mac and cheese recipe delivers restaurant-quality comfort with a modern twist—roasted squash swirls that add natural sweetness and nutty depth to every bite.
The secret lies in perfectly caramelizing the squash before blending it into the cheese sauce, creating a velvety texture that balances rich cheddar and creamy sauce. I developed this recipe after years of testing how to integrate roasted vegetables without sacrificing the classic mac and cheese experience.
The process is straightforward but precise: roast the squash until tender and caramelized, then blend it into the cheese sauce for a smooth, vibrant swirl. Boiling the pasta until al dente ensures it holds up to the creamy sauce, while a crispy breadcrumb topping adds texture contrast.
This dish transforms a simple side into a showstopper—ideal for holiday tables or weeknight dinners when you want something special without the fuss.
What makes this recipe stand out is how the roasted squash elevates the dish without overpowering the cheese. The result is a creamy, golden mac and cheese with pockets of sweet, caramelized squash that melt into every forkful.
It’s rich enough to satisfy cravings but light enough to balance heartier mains. The nutty depth from the squash pairs perfectly with the sharp cheddar, creating a flavor profile that’s both familiar and exciting.
Customize it with crispy fried shallots for extra crunch, a sprinkle of smoked paprika for warmth, or a drizzle of honey to enhance the squash’s sweetness.
Serve immediately for the best texture, or reheat gently to maintain that creamy, velvety consistency. Here’s how to make it—step by step—for foolproof results every time.

The butternut squash is the star—Trader Joe's organic variety delivers the best flavor and texture. Look for squash with smooth skin and vibrant color, avoiding any with soft spots or bruising. If you can't find organic, conventional works fine. Cutting the squash into 1-inch cubes ensures even roasting and caramelization. For the cheddar, block cheese is non-negotiable—pre-shredded contains anti-caking agents that make the sauce grainy. I recommend Cabot or Tillamook for that perfect sharpness, but any quality sharp cheddar will work. Roast the squash until tender and caramelized, which takes about 35-40 minutes at 400°F—this is where the magic happens.
No butternut squash? Delicata squash works in a pinch, though the texture will differ slightly. Short on sharp cheddar? Pepper Jack or Gruyère add great depth, though the flavor profile changes. The heavy cream can be swapped for half-and-half if you're watching fat content, though the sauce won't be as rich. For the breadcrumb topping, Japanese panko is ideal, but Italian-style breadcrumbs work too. If you're feeling fancy, add toasted pecans or fried shallots for extra crunch. The thyme is optional but adds a lovely herbal note—fresh is best, but dried works at a ratio of one-third the amount. Always taste the sauce before serving and adjust seasoning with extra salt or a splash of lemon juice if needed.
This dish reheats beautifully—gentle heat in a skillet revives the crispy topping while keeping the sauce creamy. Store leftovers in an airtight container for up to 4 days in the fridge. For longer storage, freeze portions for up to 3 months, though the breadcrumb topping may lose some crunch. To serve, garnish with extra thyme and a drizzle of honey for a touch of sweetness that complements the squash. The squash swirls add natural sweetness, so avoid adding sugar unless you're balancing a particularly sharp cheese.
Why You'll Love This Recipe
- One-Pot Magic: That roasted squash right in the sauce? No chopping, no mess—just peel, cube, and toss. The squash melts into the cheese while you stir, turning into this velvety, naturally sweetened base that tastes like it simmered all day.
- Creamy Cheese Obsession: Extra-sharp and medium-sharp white cheddar layered together? It’s a flavor bomb—sharp, tangy, and just enough creaminess from the heavy whipping cream to make every bite feel like a hug. The milk keeps it luscious without being heavy, and honestly, I’ve never met a mac that didn’t disappear faster than this one.
- Leftover Legend: This reheats like a dream—no graininess, no sad texture. Pack it for lunches, freeze half for lazy nights, or bring it to a potluck where everyone asks for seconds. Between us, I’ve had it three days in a row and still crave it.
- Budget Comfort: Butternut squash stretches the cheese further, and TJ’s pre-cubed squash (if you use it) cuts prep time in half. It’s the kind of dish where you’re feeding a crowd for less than you’d spend on takeout, and no one will guess it’s not from a fancy restaurant.
Step-by-step instructions for Trader Joe's butternut squash mac and cheese
Here's how to create a rich, nutty mac and cheese with roasted squash swirls that captures Trader Joe's signature depth.
Roast the Butternut Squash Until Caramelized
Preheat your oven to 400°F and line a baking sheet with parchment paper. Toss the 2 whole medium butternut squash (peeled, seeded, and cut into 1-inch cubes) with 1 tablespoon extra-virgin olive oil and 0.5 teaspoon sea salt. Spread them in a single layer, leaving space between each cube for even browning.
Roast for 25-30 minutes, stirring once halfway through, until the edges are deeply caramelized and the squash yields slightly when pressed. You'll know it's ready when it smells sweetly nutty and pulls away from the pan easily. Let the squash cool slightly before blending—this prevents a watery sauce later.
Cook the Elbow Macaroni to Al Dente Perfection
Bring a large pot of water to a rolling boil and add 12 oz elbow macaroni. Cook according to package directions until 1 minute before al dente—this ensures the pasta finishes cooking in the oven. Reserve 1 cup of pasta water before draining, as it contains starch that helps emulsify the cheese sauce.
Drain the pasta and return it to the pot. Toss with 1 tablespoon chopped fresh thyme leaves to infuse subtle herbal notes. Keep the pasta warm while you prepare the cheese sauce—don't let it sit too long or it'll dry out.
Create the Creamy Cheese Sauce
In a large saucepan, melt 2 tablespoons unsalted butter over medium heat. Add 2 cups extra-sharp white cheddar cheese and 1.5 cups medium sharp white cheddar cheese, stirring constantly until fully melted and smooth. Remove from heat and whisk in 1 cup heavy whipping cream and 0.5 cup warmed whole milk until combined.
Return the sauce to low heat and stir in 1 teaspoon garlic powder and 0.5 teaspoon smoked paprika. Season with 0.5 teaspoon ground black pepper and 0.5 teaspoon sea salt. The sauce should be thick but pourable—if it's too stiff, whisk in 1-2 tablespoons reserved pasta water to reach a velvety consistency.
Combine and Assemble the Baked Mac and Cheese
Transfer the cooked elbow macaroni to a large mixing bowl and pour the cheese sauce over it. Gently fold until every strand is coated, adding more pasta water if needed to loosen the mixture. Fold in the roasted butternut squash cubes, reserving a few for garnish if desired.
Transfer the mac and cheese to a greased 9x13-inch baking dish. For the crispy topping, mix 0.5 cup panko breadcrumbs, 1 teaspoon garlic powder, and 0.5 teaspoon smoked paprika in a small bowl. Sprinkle evenly over the top, pressing down gently to adhere.
Bake Until Bubbly and Golden
Bake at 375°F for 20-25 minutes until the edges are bubbling and the top is golden brown. The center should be hot but not boiling—it'll continue cooking slightly as it rests. For even browning, rotate the dish halfway through baking.
Remove from the oven and let rest for 5-10 minutes before serving. The sauce will thicken further as it sits, creating that perfect creamy texture. Garnish with reserved roasted squash cubes and extra chopped thyme leaves for freshness. Serve immediately for the best experience.
Pro Tips For Making Trader Joe'S Butternut Squash Mac And Cheese
- Peel Squash Like a Pro: Cut the squash in half lengthwise first, then scoop out the seeds with a spoon—no peeling needed. Roast it skin-on for deeper flavor, then peel just the charred outer layer after cooking. (Yes, even if you’re impatient like me, resist the urge to peel raw squash—it’s a waste of time.)
- Melt Cheese Slowly: Heat the milk and cream together until steaming, then whisk in the cheddar a handful at a time. If you dump it all in at once, you’ll end up with clumps no amount of stirring will fix. Think "low and steady," not "dump and panic."
- Don’t Overcook the Pasta: Pull the pasta out of the pot just before it’s al dente—it’ll finish cooking in the cheese sauce. Overcooked noodles turn mushy, and this dish relies on that perfect bite. (Trust me, I’ve ruined enough batches to know.)
- Finish with Cream, Not Water: Stir in the heavy cream at the very end to add richness, not to thin the sauce. If it’s too thick, splash in a little milk, but resist the urge to over-dilute—this mac should be velvety, not soupy. (And no, the cream doesn’t make it "too heavy"—it’s the point.)
Storing and reheating this recipe
Fridge Storage
Store leftovers in an airtight container for up to 4 days at 40°F or below. The breadcrumb topping stays crispier when refrigerated in a single layer, so press it down gently before covering.
I like to reheat portions in 15-minute increments to maintain texture—overheating can turn the sauce grainy. 🧊
Freezer Prep
For longer storage, freeze portions in single-serving airtight containers for up to 3 months. The breadcrumb topping may lose some crunch, so I recommend adding fresh panko when reheating. Label containers with the date—this helps track freshness. Thaw overnight in the fridge before reheating for best results. ❄️
Reheating Methods
For stovetop reheating, transfer mac and cheese to a skillet over medium-low heat. Add 1-2 tablespoons of water or milk to restore creaminess, stirring constantly until heated through (165°F internal temp). Cover with a lid to retain moisture—this prevents drying out. 🔥
Microwave Fixes
If using a microwave, cover with a damp paper towel and heat in 1-minute intervals on 50% power. Stir between intervals to distribute heat evenly. The sauce may thicken slightly, so add a splash of milk if needed. Avoid reheating directly from frozen—thaw first for even cooking. ⏳
Crispy Topping Revival
To restore the breadcrumb topping, sprinkle fresh panko over the reheated dish and broil for 1-2 minutes until golden. For extra crunch, mix panko with 1 tbsp melted butter before sprinkling. This works best when reheating from the fridge, not frozen. 🍞
Garnish Refresh
Brighten reheated mac and cheese with fresh garnishes like chopped thyme, smoked paprika, or a drizzle of honey. The sweetness of honey complements the roasted squash beautifully. For added richness, top with a dollop of sour cream or hot sauce—this balances any texture changes from reheating. 🌟

Frequently asked questions
Can I make this recipe without roasting the butternut squash?
You can, but the flavor will be less developed. For a quick version, steam or boil 1 cup cubed squash until tender (8-10 minutes), then blend it into the cheese sauce. The texture will be softer, and you'll miss the caramelized sweetness that makes this dish special.
What's the best cheese substitute if I don't have sharp cheddar?
Try Gruyère for nutty depth or Pepper Jack for a mild kick. Avoid mild cheddar—it won't provide the same sharpness. For extra richness, blend ½ cup sharp cheddar with ½ cup Monterey Jack. Always shred your own cheese to prevent graininess in the sauce.
Why did my mac and cheese turn out too thick?
This usually happens from overcooking the pasta or not using enough pasta water. Next time, cook pasta just 1 minute before al dente and reserve 1.5 cups pasta water. Stir in 2 tbsp at a time until the sauce reaches a smooth, creamy consistency.
Can I make this ahead of time for a party?
Yes! Assemble the dish (without baking) up to 24 hours ahead and refrigerate in an airtight container. Bake straight from the fridge, adding 5-10 extra minutes at 375°F. For a crowd, double the recipe and use two 9x13-inch pans.
How can I make this dish vegetarian or vegan?
For vegetarian, use vegetarian butter and dairy-free cheese (like Violife or Miyoko's). For vegan, replace cheese with cashew cream sauce (blend 1 cup soaked cashews + 1 cup water + 1 tbsp nutritional yeast) and use vegan pasta. The squash will still shine as the sweet component.
