Ingredients

Butternut Squash: This vibrant orange squash adds a natural sweetness and creamy texture to the dish once roasted. Look for a firm squash without any blemishes. For easier prep, use pre-cut butternut squash cubes from the grocery store. 

Garlic: Adds dimensional and nutty undertones to the vegan macaroni and cheese sauce. Choose a fresh and smooth garlic clove for the best flavor.

Arrowroot Powder: A thickening agent for the cheese sauce that is also gluten-free. Substitute 1:1 with cornstarch if preferred. 

Non-Dairy Milk: Choose your favorite plant-based milk, such as almond, soy, or oat, to provide a creamy base for the cheese sauce. Opt for an unsweetened variety to avoid added sugars and ensure a neutral flavor. 

Grapeseed Oil: The higher smoke point is ideal for roasting the butternut squash and garlic and cooking the cheese sauce. If desired, use another neutral-flavored oil, like canola or melted vegan butter, for a creamier taste. 

Dijon Mustard: Enhances the cheesy flavor with a tangy profile. Use a smooth blend of Dijon mustard to create a smooth sauce for the butternut squash vegan mac and cheese. For a more textured sauce, use whole-grain mustard. 

Onion Powder: Adds depth of flavor without the heartier texture of raw onion. Adjust the quantity to taste. 

Lemon Juice: Freshly squeezed lemon juice brightens the sauce with acidity that balances the richness of the vegan butternut mac and cheese. Use fresh lemon juice for the best flavor, but store-bought will work in a pinch. 

Nutritional Yeast: Key to providing the dairy-free butternut squash mac and cheese with a cheesy flavor and adds nutritional value with B vitamins. Adjust the amount to taste based on the desired cheesiness. 

Sea Salt: Fine sea salt enhances the flavors throughout the dish. Use sparingly and adjust to taste. Kosher salt or Himalayan pink salt can also be used as an alternative.

Macaroni Pasta: Traditionally-shaped elbow macaroni or a similar small-shaped pasta works best in this dish. Cook the noodles al dente for a firm texture that holds up to baking. 

Panko Bread Crumbs: Though this ingredient is optional, toasted panko adds a delightful crunch to the mac & cheese.

Parsley: Garnish your finished mac and cheese with fresh parsley.

How to Make Vegan Butternut Squash Mac and Cheese

• Steam the Butternut Squash. Fit a large pot or Dutch oven with a steamer basket. Add 1 1/2 inches of water to the pot and bring it to a boil over medium-high heat. Add the butternut squash to the basket, cover, and steam for 15 minutes or until very tender.

• Prepare Arrowroot Paste. Whisk the arrowroot powder and ⅓ cup of the milk in a small mixing bowl until smooth. Set aside.

• Sauté Garlic. Warm a saucepan over medium heat on the stovetop. Add the oil or vegan butter and heat until melted. Add the minced garlic and saute for 1-2 minutes, until just golden brown.

• Prepare Cheese Sauce. Add the remaining soy milk, Dijon mustard, onion powder, lemon juice, nutritional yeast, and salt to the saucepan. Whisk to combine.

• Add Arrowroot Paste. Whisk the arrowroot milk mixture into the saucepan. Cook over medium-low heat, whisking regularly, for about 3 minutes or until thickened.

• Prepare Pasta. Cook the pasta according to the package directions until al dente or still slightly chewy. Drain the noodles well, then cool them in a deep baking dish.
• Blend Cheese Sauce. Transfer the sauce to a blender and add the butternut squash and roasted garlic. Blend until smooth and season with more nutritional yeast and salt to taste. The sauce should taste quite salty to balance the noodles.

• Combine Cheese Sauce & Noodles. Pour the cheese sauce over the noodles and stir well to coat.

Recipe Pro-Tips

• Evenly cut the butternut squash. Cut the butternut squash into even-sized cubes to ensure uniform roasting. If you’re short on time, many stores offer pre-cut butternut squash.
• Optional: Roast the butternut squash. Roasted squash instead of steamed squash provides a more naturally sweet, caramelized finish to the cheese sauce! Toss the cubed squash with 1 tablespoon of oil and roast in an oven preheated to 375°F for 30 minutes or until golden brown and tender.
• Thoroughly blend the cheese sauce. Use a high-speed blender or food processor to blend the roasted butternut squash and garlic with the cheese sauce. This will create a silky-smooth texture and creamy consistency. 
• Properly cook the pasta. Heavily salt the pasta water to enhance the flavor of the noodles, and cook the pasta until al dente. The noodles will continue to cook slightly when baked, so cooking until just firm will prevent mushiness. 
• Adjust seasonings to taste. Feel free to add more nutritional yeast, salt, and other spices to suit your preferences. The cheese sauce should be slightly saltier than you think, as the pasta will absorb some of it.

Recipe Variations

Below are optional variations to switch up this butternut mac and cheese vegan recipe:

• Gluten-Free: Use a small-sized gluten-free pasta shape and ensure the arrowroot powder or cornstarch is certified gluten-free.
• Spicy Kick: Add more red chili flakes or mix in a diced jalapeño pepper to the sauce for an extra spicy version. 
• Herbs: Include fresh or dried herbs such as thyme, rosemary, or sage in the sauce for a more aromatic and flavorful dish. 
• Greens: Add sautéed spinach, kale, or Swiss chard to the pasta for added nutrients and a pop of vibrant green color. 
• Protein Boost: Incorporate cooked lentils, chickpeas, or crumbled tofu into the pasta to add more protein. 
• Creamy Cauliflower: To make a lighter yet still creamy sauce, substitute half of the butternut squash with roasted cauliflower.
