Ingredients for trader joe's butternut squash mac and cheese
Creamy cheddar meets caramelized squash swirls—this vegetarian masterpiece transforms simple pantry staples into restaurant-quality comfort.
| Ingredient | Amount | Notes |
|---|---|---|
| Medium Butternut Squash 🎃 | 1 ½ lb | Peeled, seeded, cut into 1-inch cubes |
| Extra-Sharp White Cheddar Cheese 🧀 | 2 cups | Shredded, block preferred for freshness |
| Medium Elbow Macaroni 🍝 | 12 oz | Dry weight, al dente preferred |
| Unsalted Butter 🧈 | ½ cup | Cold, cut into cubes for roasting |
| Heavy Cream 🥛 | ½ cup | Full-fat for optimal creaminess |
| Whole Milk 🥛 | ½ cup | Warmed for smooth sauce |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste, don't over-salt |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Cracked peppercorns preferred |
| Panko Breadcrumbs 🍞 | ½ cup | Trader Joe's brand for extra crisp |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For roasting squash and breadcrumbs |
| Fresh Nutmeg 🌿 | ¼ tsp | Finely grated, aromatic |
| Garlic Cloves 🧄 | 2 cloves | Minced, for roasting squash |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated, for breadcrumb mix |
| Dried Thyme 🌿 | ½ tsp | Or 1 tsp fresh thyme leaves |
The butternut squash is the star—Trader Joe's organic variety delivers the best balance of sweetness and texture. Roast until caramelized to deepen its natural sugars, which harmonize with the sharp cheddar. For optimal results, use a block of cheese and shred it yourself—the pre-shredded kind contains anti-caking agents that prevent proper melting. The Panko brand matters here; Trader Joe's version stays crisp even after baking, while store-brand alternatives often turn soggy. Fresh nutmeg is non-negotiable for that autumnal depth—pre-ground loses potency quickly, so grate your own from a whole nutmeg if possible.
No butternut squash? Sweet potato cubes work in a pinch, though they won't caramelize as beautifully. Substituting sharp cheddar? Gruyère or smoked Gouda add complexity, but the sharpness is key to balancing the squash's sweetness. For the breadcrumb topping, crushed cornflakes can replace half the Panko if you're out, though the texture will differ slightly. The garlic and thyme in the roasting process are essential—they infuse the squash with aromatic depth that elevates the entire dish. If you're using fresh thyme, double the amount listed for dried, as fresh herbs pack more flavor.
Roasted squash keeps 5 days in the fridge, fully submerged in water to preserve its vibrant color. The breadcrumb topping stays crisp for 3 days if stored in an airtight container, though it's best served fresh. For meal prep, assemble the dish without baking, then refrigerate and bake straight from the fridge—this ensures the breadcrumbs crisp properly. The entire mac and cheese reheats beautifully; cover with foil for 5 minutes to melt the cheese evenly before serving. Portion into individual containers for grab-and-go lunches, or double the recipe for holiday gatherings—this dish freezes exceptionally well for up to 3 months
Why You'll Love This Recipe
- No Peel, No Stress: I’ll admit, I used to dread squash—peeling, seeding, all of it. But this recipe? You just roast the whole thing, skin and all. The flesh gets tender enough to mash right into the cheese sauce, and honestly? That caramelized skin adds this deep, nutty sweetness that makes it taste like you slaved over it.
- Creamy Without the Guilt: Between us, I usually skip heavy cream in mac and cheese. But here, it’s worth it—the richness balances the sharp cheddar so perfectly, and the squash soaks it up like a dream. Plus, the butter? Just enough to make it velvety, not greasy. (Yes, even on a Tuesday night.)
- Leftover Magic: This dish actually improves the next day. The flavors meld, the squash gets even sweeter, and it reheats like a dream—no clumping, no sad texture. I’ve sent it to work lunches, frozen portions for lazy Sundays, and my kid still begs for it. (She’s not wrong.)
- Budget-Friendly Luxury: You’d think a recipe with heavy cream and cheddar would break the bank, but Trader Joe’s prices make this a steal. The squash is cheap, the pasta’s a bulk-bin staple, and you’re using whole ingredients—not pre-shredded cheese or powdered stuff. Feels fancy, costs next to nothing.
Step-by-step instructions for roasted butternut squash mac and cheese
This method delivers velvety cheese sauce with caramelized squash swirls and golden breadcrumb topping.
Roast the Butternut Squash Until Caramelized
Preheat your oven to 400°F and line a rimmed baking sheet with parchment paper. In a large bowl, toss the 1.5 lb medium butternut squash cubes with 0.25 cup extra-virgin olive oil, 2 minced garlic cloves, 0.5 tsp dried thyme, 0.5 tsp freshly ground black pepper, and 0.75 tsp diamond crystal kosher salt. Spread the squash in a single layer on the prepared baking sheet.
Roast for 25-30 minutes, stirring once halfway through, until the squash is tender when pierced with a fork and develops golden-brown caramelization. The edges should be slightly crisp while the centers remain soft. This roasting process intensifies the natural sweetness of the squash and creates those beautiful swirls in the final dish.
Cook the Macaroni to Al Dente Perfection
While the squash roasts, bring a large pot of water to a rolling boil and add 1.5 tsp diamond crystal kosher salt. Add the 12 oz medium elbow macaroni and cook until 1 minute before al dente according to package directions. The pasta should have a slight bite to prevent overcooking in the cheese sauce. Reserve 1 cup pasta water before draining completely.
I like to save a small handful of pasta water because it helps emulsify the cheese sauce later. The starchy water acts as a natural thickener and prevents the sauce from becoming grainy. Drain the pasta and return it to the pot, setting it aside with the reserved water.
Create the Ultimate Cheese Sauce
In a large, deep skillet, melt 0.5 cup unsalted butter over medium heat. Add the shredded 2 cups extra-sharp white cheddar cheese and 0.25 cup freshly grated parmesan cheese, stirring constantly until the cheese melts completely and forms a smooth sauce. Remove from heat and whisk in 0.5 cup heavy cream and 0.5 cup warmed whole milk.
Return the skillet to low heat and gradually whisk in the cooked macaroni along with the reserved pasta water, 1 tablespoon at a time, until the sauce reaches your desired consistency. The sauce should coat the back of a spoon but still be pourable. Stir in the roasted butternut squash and 0.25 tsp freshly grated nutmeg, mixing gently to create those signature swirls.
Prepare the Crispy Breadcrumb Topping
In a small bowl, combine 0.5 cup panko breadcrumbs, 0.25 cup extra-virgin olive oil, and 0.25 tsp diamond crystal kosher salt. Mix until evenly coated. Spread the breadcrumb mixture on a separate baking sheet in an even layer.
Bake at 375°F for 5-7 minutes, stirring once halfway through, until the breadcrumbs are deep golden brown and crisp to the touch. The key is to watch them closely—they go from perfect to burnt in seconds. Remove from oven and set aside until ready to use.
Assemble and Bake to Golden Perfection
Transfer the macaroni mixture to a greased 9x13-inch baking dish and spread evenly. Sprinkle the crispy breadcrumb topping over the entire surface, pressing down gently to help it adhere. The contrast between the creamy macaroni and crispy topping creates the perfect textural experience.
Bake at 375°F for 15-20 minutes until the edges are bubbly and the topping is uniformly golden brown. The cheese sauce should be fully set but still creamy when cut. Let rest for 5 minutes before serving to allow the layers to set slightly. This resting period ensures clean slices without losing any filling.
Pro Tips For Making Trader Joe'S Butternut Squash Mac And Cheese
- PEEL AND CUBE SMALL: Cut the butternut squash into 1-inch cubes—no need to peel. The skin softens into the sauce and adds texture, while smaller pieces cook faster and blend smoother. I used to slice them too thin and end up with mushy, watery purée every time.
- MELT CHEESE LOW AND SLOW: Stir the heavy cream and butter into the shredded cheddar over low heat, or you’ll end up with scrambled cheese. Keep it at a simmer, not a boil, and add the squash purée last—this keeps the sauce creamy, not greasy.
- DON’T DRAIN THE PASTA: Reserve 1 cup of pasta water before draining. The starchy water binds the sauce to the noodles, and skipping it means a dry, clumpy mess. Add it back in tablespoon by tablespoon until the sauce clings like it should.
- TOAST THE NOODLES: Cook the elbow macaroni al dente, then toss it in a dry skillet over medium heat for 2-3 minutes. The slight crispness cuts through the richness of the squash and cheese, and it’s the one thing that makes this dish feel restaurant-quality.
Regional styles of trader joe's butternut squash mac and cheese
New England Creamy Twist
Inspired by classic New England clam chowder, this version swaps clams for roasted butternut squash while keeping the creamy, comforting essence. Use 2 cups of sharp white cheddar and add ½ cup of heavy cream to the cheese sauce for extra richness.
Top with toasted breadcrumbs mixed with 1 tbsp of chopped chives and a sprinkle of smoked paprika for a smoky depth. Serve with a side of crusty sourdough bread for dipping—this regional take feels like a cozy autumn dinner. 🍂
Southern Comfort Style
For a Southern-inspired version, fold ½ cup of cooked, crumbled bacon into the cheese sauce and stir in 1 tsp of hot sauce (like Crystal or Tabasco) for a tangy kick.
Replace half the Panko with crushed cornflakes for a lighter topping, and finish with 2 tbsp of chopped green onions. This version pairs perfectly with collard greens or cornbread—ideal for a hearty vegetarian Southern feast. 🌶️
Italian-Inspired Squash Swirl
Elevate this dish with Italian flair by adding ½ cup of grated fontina cheese to the cheddar blend and stirring in 1 tsp of dried oregano with the roasted squash. For the topping, mix Panko with ¼ cup of freshly grated Parmesan and 1 tbsp of chopped sun-dried tomatoes.
Serve with a side of garlic knots or a simple arugula salad dressed with lemon vinaigrette. The fontina adds a nutty depth that complements the squash beautifully. 🍅
Spicy Southwest Fusion
Transform this mac and cheese into a Southwest-inspired dish by adding 1 tsp of adobo sauce (from canned chipotles) to the cheese sauce and stirring in ½ cup of black beans, drained and rinsed.
Top with a mix of Panko, ¼ cup of crushed tortilla chips, and 2 tbsp of chopped cilantro. Serve with avocado slices and a dollop of sour cream for a vibrant, spicy twist that’s perfect for a vegetarian taco night. 🌶️🔥
French-Inspired Truffle Mac
For a French-inspired version, fold 1 tbsp of truffle oil into the cheese sauce and garnish with freshly cracked black pepper and a few shavings of black truffle (if available). Replace the breadcrumb topping with toasted baguette slices, lightly buttered and toasted until golden.
Serve with a side of roasted Brussels sprouts or a simple green salad with a balsamic glaze. The truffle oil adds an earthy luxury that feels distinctly French. 🥖✨
Gluten-Free Adaptation
For a gluten-free version, replace the Panko with gluten-free breadcrumbs (like Trader Joe’s gluten-free panko) and use gluten-free elbow macaroni. To enhance the topping, mix in 1 tbsp of chopped walnuts for crunch and a touch of nutmeg for warmth.
This adaptation keeps all the creamy, cheesy goodness while making it safe for gluten-sensitive diners. 🌾

Frequently asked questions
Can I make this mac and cheese without roasting the butternut squash?
Roasting enhances the squash's natural sweetness and caramelization, but you can steam or boil it for 8-10 minutes until tender if preferred. However, the flavor will be less developed, and the dish won't have the same depth of flavor. For best results, stick with roasting—it's the secret to that restaurant-quality taste!
How do I prevent the breadcrumb topping from getting soggy?
Bake the breadcrumbs separately on their own baking sheet first for 5-7 minutes until golden and crisp. Then sprinkle them over the assembled mac and cheese just before the final bake. This two-step method ensures maximum crispiness. For extra insurance, press down gently with a spatula to help them adhere.
What's the best way to reheat leftovers?
Cover with foil and reheat in the oven at 350°F for 10-15 minutes until warmed through. The foil prevents the breadcrumbs from drying out, while the oven keeps the cheese creamy. Microwaving works in a pinch, but it can make the topping soggy—always cover with a damp paper towel for even heating.
Can I make this vegetarian dish with vegan cheese?
Yes, but expect a different texture and flavor profile. Use 2 cups of vegan sharp cheddar and add 1 tbsp of nutritional yeast for depth. The sauce may be slightly thinner, so reduce the milk by ¼ cup and stir in 1 tbsp of cornstarch mixed with water to thicken. The breadcrumb topping will still crisp up beautifully!
Why did my cheese sauce turn grainy?
Graininess usually happens from overheating or not enough liquid. Always melt cheese over low heat and whisk constantly. If it gets too thick, add reserved pasta water 1 tbsp at a time. For extra smoothness, whisk in 1 tbsp of cold heavy cream at the end to help emulsify the sauce.
