Trader Joe's Butternut Squash Mac and Cheese Recipe: Roasted Squash Meets Creamy Cheese Comfort

Recreating Trader Joe's butternut squash mac and cheese at home delivers that signature creamy, slightly sweet comfort in every bite. The roasted squash adds natural sweetness while keeping the dish rich and satisfying—just like the store version, but made with fresh ingredients and precise technique.

I've perfected this recipe over years of testing, ensuring the cheese sauce stays velvety smooth without separating.

This recipe combines tender elbow macaroni with roasted butternut squash cubes, all blanketed in a foolproof cheese sauce made from sharp cheddar, Gruyère, and a touch of cream. The roasting process caramelizes the squash naturally, enhancing its sweetness while maintaining a pleasant texture.

No special equipment is needed—just a baking dish and about 45 minutes of active time.

What sets this apart is the balance of flavors: the creamy cheese sauce complements the roasted squash's natural sweetness, while a sprinkle of breadcrumbs on top adds texture. The result is a side dish that feels indulgent yet stays true to Trader Joe's signature taste.

Perfect for weeknight dinners or holiday gatherings, this mac and cheese delivers restaurant-quality comfort at home.

For those watching their dairy intake, a dairy-free version is possible using nutritional yeast and coconut milk, though the texture will differ slightly. The key to success lies in the roasting and sauce-making—both require patience but yield unbeatable results. Let's get started on recreating this crowd-pleaser.

Ingredients for trader joe's butternut squash mac and cheese

Fresh roasted squash meets velvety Gruyère and cheddar for Trader Joe's signature comfort in every bite.

The butternut squash is the foundation—organic, sweet varieties like Sugar Pie yield the best results. Trader Joe's organic squash works perfectly, but avoid firm, fibrous specimens. Peel and cube uniformly to ensure even roasting. For optimal flavor, roast at 425°F (220°C) until caramelized at the edges. Gruyère is non-negotiable here; Whittard of Chelsea or Murray's Cheese brands deliver the nutty depth Trader Joe's achieves. If substituting, aged Gouda comes closest, though texture differs slightly.

No Gruyère? Extra-sharp white cheddar plus a splash of cream cheese mimics the creaminess, though the flavor profile shifts. For dairy-free adaptation, nutritional yeast plus full-fat coconut milk creates a cheesy note, but expect a denser texture. The breadcrumbs should be toasted in butter for added richness—Panko from Trader Joe's is ideal. Pre-shredded cheese? Always pulse in a food processor to mimic freshly grated texture. The garlic cloves should be minced finely before roasting to infuse the squash with subtle depth.

Roasted squash keeps 5 days refrigerated in an airtight container, though best within 3 days for peak texture. The cheese sauce reheats beautifully—low heat, stirring constantly prevents separation. For make-ahead convenience, assemble the dish day-of-serving and bake immediately. Leftovers freeze for 3 months when stored in a sealed container, though texture may soften slightly upon reheating. Always sprinkle breadcrumbs fresh post-baking for optimal crunch.

Step-by-step instructions for roasted butternut squash mac and cheese

A rich, velvety sauce meets caramelized squash in this elevated mac and cheese. Here's how to achieve that perfect balance of texture and depth.

Preheat your oven to 400°F and line a rimmed baking sheet with parchment paper. Toss the 1.5 lb medium butternut squash, cut into 1-inch cubes, with 2 tbsp extra-virgin olive oil, 2 cloves minced garlic, and ½ tsp freshly ground black pepper. Spread in a single layer, ensuring the pieces don't overlap.

Roast for 25-30 minutes, stirring once halfway through, until the squash is tender when pierced with a fork and the edges are deep golden brown. The squash should smell sweetly caramelized—this is your cue it's ready. Let it cool slightly before transferring to a food processor for blending.

While the squash roasts, bring a large pot of water to a rolling boil and add 12 oz elbow macaroni. Season generously with 1 tsp diamond crystal kosher salt—the water should taste like the sea. Cook until 1 minute before the package instructions for al dente texture. Drain immediately, reserving ½ cup pasta water for the sauce.

Rinse the pasta briefly under cold water to stop the cooking process, then transfer to a large mixing bowl. This step prevents overcooking and ensures the macaroni stays firm when mixed with the sauce later.

In a separate saucepan, melt 4 tbsp unsalted butter over medium heat. Add 3 cups shredded sharp white cheddar cheese and 1 cup shredded Gruyère cheese, stirring constantly until fully melted and smooth. Remove from heat and whisk in 1 cup heavy cream, ½ cup whole milk, and ½ cup coconut milk (for depth and creaminess).

For a dairy-free option, stir in 2 tbsp nutritional yeast at this stage. The sauce should be luxuriously thick but still pourable. If it's too stiff, add 2-3 tbsp reserved pasta water to reach a velvety consistency. Season with ½ tsp freshly ground black pepper and ½ tsp diamond crystal kosher salt.

Transfer the roasted squash to a food processor and blend until smooth, scraping down the sides as needed. You want a silky purée with no visible chunks. With the motor running, slowly drizzle in ½ cup whole milk to thin the mixture to a pourable consistency.

Pour the squash purée over the cooked macaroni in the mixing bowl. Gently fold in the cheese sauce until fully combined and the pasta is evenly coated. The result should be a vibrant orange sauce with pockets of creamy cheese. Taste and adjust seasoning—this is where the magic happens.

Transfer the mac and cheese to a greased 9x13-inch baking dish and sprinkle evenly with ¼ cup toasted panko breadcrumbs. Bake at 375°F for 20-25 minutes until the top is golden brown and bubbling at the edges. The cheese should pull away slightly from the sides of the dish.

For the final touch, broil for 1-2 minutes to achieve a crispy, caramelized crust. Watch closely to avoid burning. Let it rest for 5 minutes before serving—this allows the sauce to set slightly and makes it easier to scoop.

Perfect pairings for these flavors

Protein Additions

This mac and cheese shines with crispy bacon or pulled pork—just fold in ½ cup cooked bacon crumbles or 1 cup shredded pulled pork during the final assembly step.

For extra richness, I like to add ½ cup cooked ground turkey or diced ham for a lighter but still satisfying protein boost. 🥓

Vegetable Boosters

Roasted Brussels sprouts or sautéed kale add fiber and color without overpowering the dish. Toss 1 cup halved Brussels sprouts with olive oil, salt, and pepper, then roast alongside the squash.

Fold them in with the macaroni before baking. For a greener twist, wilt 2 cups chopped kale in the cheese sauce for 2 minutes before combining with the pasta. 🥦

Crunchy Toppings

Swap panko for crushed tortilla chips or fried shallots for a Tex-Mex inspired crunch. I also love a sprinkle of toasted pecans or chopped walnuts for nutty depth. For extra indulgence, top with crumbled bacon or bacon bits before baking. 🌰

Herb Garnishes

Fresh herbs elevate the dish effortlessly. A sprinkle of chopped chives or parsley adds brightness, while thyme leaves complement the Gruyère's nutty flavor. For a smoky note, try crumbled fried sage or a pinch of smoked paprika over the breadcrumbs. 🌿

Beverage Pairings

A crisp Chardonnay or Sauvignon Blanc cuts through the richness beautifully. For beer lovers, a hoppy IPA or Belgian witbier balances the creamy, sweet flavors. Sparkling apple cider adds a refreshing contrast during fall gatherings. 🍷

Dessert Follow-Up

Serve with warm apple crisp or pumpkin bread for a cozy dessert pairing. A scoop of vanilla bean ice cream or a drizzle of caramel sauce completes the meal. For a lighter option, offer honey-drizzled pecans or dark chocolate squares. 🍎
