Ingredients for trader joe's butternut squash mac and cheese

Six ingredients make the creamy base, four transform it into restaurant-quality perfection.

The Trader Joe's butternut squash is the star—pick a piece with vibrant orange color and no soft spots. Pre-cut cubes save time, but if using whole squash, roast until fork-tender for maximum sweetness. For the cheeses, aged sharp cheddar (like Cabot) and Monterey Jack (Sargento brand melts beautifully) are non-negotiable. The Parmesan should be freshly grated—pre-shredded turns the sauce grainy. Trader Joe's carries all three at reasonable prices, and their organic options work perfectly. Fresh herbs? Whole Foods or local markets have the brightest thyme and parsley, but grocery store bunches work if used within 3 days.

No sharp cheddar? Gruyère or extra-sharp white cheddar at half the quantity delivers similar depth. Substituting milk? Half-and-half or light cream works, but the texture won't be as velvety. For the crispy herb topping, panko plus extra Parmesan gives the same crunch without breadcrumbs. The squash can be roasted ahead—reheat gently in the sauce to maintain moisture. Want extra richness? Swap half the milk for cream cheese, blended smooth. The garlic should be freshly minced—jarred lacks the punch, and pre-minced turns bitter when roasted.

Roasted squash keeps 5 days in the fridge, but fold it into the sauce immediately for best texture. The assembled mac and cheese reheats beautifully—cover with foil and warm at 350°F for 15 minutes. For make-ahead meals, assemble without the crispy topping, refrigerate, then bake topped with breadcrumbs for 10 minutes at 400°F before serving. Freezes for 3 months when fully cooled. Portion into individual containers for easy lunches—just add a sprinkle of fresh herbs when reheating to revive the flavor.

Step-by-step instructions for Trader Joe's butternut squash mac and cheese

Here's how to create a rich, creamy mac and cheese with perfectly roasted squash swirls and a crispy herb topping.

Preheat your oven to 400°F. Toss the 2 lbs Trader Joe's butternut squash (pre-cut into 1-inch cubes) with 2 tablespoons extra-virgin olive oil, 1 teaspoon salt, and ¼ teaspoon ground black pepper. Spread the squash in a single layer on a rimmed baking sheet, ensuring the pieces don't overlap.

Roast for 25-30 minutes, stirring halfway through, until the edges are caramelized and the squash easily pierces with a fork. The squash should be soft inside but still hold its shape when pressed. Let it cool slightly before transferring to a food processor.

Bring a large pot of salted water to a boil and cook the 1.5 cups elbow macaroni for 1 minute less than the package instructions (about 11-12 minutes). Drain the pasta, reserving ½ cup pasta water, and set aside.

In a large skillet over medium heat, melt the 2 tablespoons unsalted butter. Add the 4 minced garlic cloves and sauté for 30 seconds until fragrant. Pour in the 1 cup heavy cream and 1 cup whole milk, simmering for 3-4 minutes until slightly thickened. Gradually whisk in the 2 cups sharp cheddar cheese, 1 cup Monterey Jack cheese, and ½ cup Parmesan cheese until fully melted and smooth.

Add the cooked macaroni and ½ cup reserved pasta water to the cheese sauce, tossing until fully coated. Transfer the mixture to a large bowl and fold in the roasted squash, breaking it into small chunks as you incorporate it evenly. Season with the remaining ½ teaspoon salt and ¼ teaspoon ground black pepper. The squash should be distributed throughout the mac and cheese, creating those signature swirls.

For extra richness, cover the bowl and let the mac and cheese sit off the heat for 5 minutes to allow the flavors to meld.

In a small bowl, combine the ½ cup Panko breadcrumbs, ¼ cup chopped fresh thyme leaves, and ¼ cup chopped fresh parsley leaves. Drizzle with 1 tablespoon extra-virgin olive oil and toss until evenly coated. Spread the mixture on a small baking sheet and bake at 375°F for 5-6 minutes until golden brown, stirring once halfway through. Keep the topping warm until ready to use.

Transfer the mac and cheese to a serving dish and top generously with the crispy herb mixture. The contrast of the creamy, cheesy pasta with the roasted squash and crispy topping creates a perfect balance of textures and flavors. Serve immediately while the topping is still crispy and the mac and cheese is warm.

This dish delivers on the promise of crispy topping and creamy, flavorful mac and cheese with the added sweetness of roasted butternut squash. Each bite combines the richness of the cheese sauce, the earthy sweetness of the squash, and the satisfying crunch of the herb topping.

Dietary considerations for these flavors

Dairy-Free Adaptation

For a dairy-free version, swap the cheeses for a blend of nutritional yeast (½ cup) and cashew cream (blend 1 cup soaked cashews with 1 cup water until smooth).

Use coconut milk instead of dairy milk and heavy cream. The squash and pasta will still shine, though the texture will be slightly lighter. 🌱

Gluten-Free Option

Replace the elbow macaroni with gluten-free pasta like Barilla GF or Jovial. Cook it 1 minute longer than regular pasta since GF noodles can be denser. For extra creaminess, stir in 2 tablespoons cornstarch with the cheese sauce to help bind the sauce.

Cut carbs by using cauliflower mac and cheese instead of pasta. Steam 4 cups riced cauliflower until tender, then mix it into the cheese sauce. For a heartier dish, add ½ cup cooked quinoa or shredded chicken. The butternut squash adds natural sweetness that balances the richness beautifully.

Make this dish fully plant-based by using vegan butter, cashew cream, and vegan cheeses like Miyoko's or Violife. Add 1 tablespoon nutritional yeast to the sauce for a cheesy flavor. The roasted squash and crispy herb topping (use vegan panko) keep the dish satisfying and flavorful.

Add ½ lb cooked chicken breast, ½ lb ground turkey, or ½ cup black beans to the mac and cheese for extra protein. For a meatless option, stir in ½ cup chickpeas or ½ cup lentils.

The protein blends seamlessly with the creamy sauce and sweet squash, making this a complete meal.

Nut-Free Allergy-Friendly

For nut-free adaptations, avoid cashew cream and use oat milk or coconut milk instead. Skip nutritional yeast if allergies are severe, and boost flavor with extra garlic and herbs. The squash and cheese still deliver rich, satisfying flavors without relying on nuts or dairy substitutes.
