Let’s Get Cooking! Your Step-by-Step Guide

Ready to create the creamiest, most delicious mac and cheese ever? Let’s get started.

Part 1: The Creamy Butternut Squash Sauce

1. Simmer the Squash: In a medium saucepan, combine the cubed butternut squash, broth, milk, and minced garlic. Bring the mixture to a boil over medium-high heat, then reduce the heat to medium-low and let it simmer for about 20 minutes. The squash should be very tender and easily pierced with a fork.
2. Cook the Pasta: While the squash is simmering, preheat your oven to 375°F (191°C) and bring a large pot of salted water to a boil. Cook your pasta just until al dente (still a little firm). If you’re using kale, add it to the pasta water for the last 1-2 minutes of cooking. Drain the pasta and kale together.
3. Blend the Sauce: Carefully pour the warm butternut squash mixture (including all the liquid) into a blender or food processor. Add the Greek yogurt, salt, pepper, and nutmeg. Secure the lid tightly and blend until the sauce is completely smooth and velvety.

Part 2: Assemble and Bake to Bubbly Perfection

4. Combine Sauce and Pasta: Pour the blended butternut squash sauce into a very large bowl. Stir in the shredded cheese until it’s combined (it’s okay if it doesn’t melt all the way). Give the sauce a taste and add more seasonings if you like. Add the drained pasta and kale to the sauce and stir until everything is beautifully coated.
5. Assemble the Casserole: Pour the entire mixture into an ungreased 9×13-inch baking pan or a similar-sized oven-safe dish. It will look quite saucy, but the pasta will absorb the liquid as it bakes.
6. Top and Bake: Sprinkle the top with breadcrumbs and an extra handful of cheese, if desired. Cover the dish with aluminum foil and bake for 20 minutes.
7. The Final Golden Touch: Remove the foil and bake for another 5 minutes, or until the sauce is hot and bubbling around the sides and the top is lightly golden.
8. Rest and Serve: Let the mac and cheese rest for a few minutes before serving. Garnish with a sprinkle of fresh thyme leaves or extra black pepper.

• 1–2 cups roughly chopped kale stems discarded (optional)
• 1/3 cup plain Greek yogurt (80g)

Equipment

• Large Pot
• Blender or Food Processor
• 9×13-inch baking pan or similar 3-4 quart dish

Method

 

1. Combine the squash, broth, milk, and garlic in a medium saucepan over medium-high heat. Bring to a boil, then reduce heat and simmer for 20 minutes, until the squash is very tender.
2. Meanwhile, preheat oven to 375°F (191°C). Cook the pasta in a large pot of boiling salted water until al dente. If using kale, add it during the last 1-2 minutes of cooking. Drain pasta and kale.
3. Pour the warm butternut squash mixture (with all its liquid) into a blender. Add the yogurt, salt, pepper, and nutmeg. Blend until completely smooth.
4. Pour the blended sauce into a very large bowl. Stir in the shredded cheese until combined. Add the drained pasta and kale to the sauce and stir to coat.
5. Pour the mixture into a 9×13-inch baking pan or similar 3-4 quart dish. Top with breadcrumbs and an extra sprinkle of cheese, if desired.
6. Cover with aluminum foil and bake for 20 minutes. Remove the foil and bake for another 5 minutes, until bubbly on the sides and lightly golden on top.
7. Let rest for a few minutes before serving. Garnish with fresh thyme or extra pepper if desired.

Notes

Undercook Pasta: Cook the pasta just to al dente as it will continue to cook in the oven. This is key to preventing a mushy final dish.

Smooth Sauce: Ensure the butternut squash is very soft before blending for the creamiest, most velvety sauce.

Make Ahead: This casserole can be fully assembled up to a day in advance. Cover and refrigerate, then add 10-15 minutes to the covered baking time.

WiseRecipes’ Top Tips for the Creamiest Mac and Cheese

These simple secrets will ensure your butternut squash mac and cheese is a flawless, flavorful triumph.

1. Cook the Squash Until Very Tender. For the absolute smoothest, most velvety sauce, make sure your squash is completely soft after simmering. It should offer no resistance when pierced with a fork. This ensures it blends perfectly.
2. Undercook Your Pasta Slightly. The pasta will continue to cook in the hot sauce in the oven. Cooking it just to al dente is the key to ensuring it doesn’t become mushy in the final baked dish.
3. Grate Your Own Cheese. For the best, smoothest melt, always grate your cheese from a block. Pre-shredded cheese contains anti-caking agents that can give your sauce a slightly grainy texture.
4. Don’t Be Alarmed by the Soupy-ness! When you first mix the pasta and sauce, it will look like there is a lot of liquid. Trust the process! The starchy pasta will absorb a good amount of that delicious sauce as it bakes, creating the perfect creamy consistency.
5. Baking Covered is Key. The initial 20 minutes of baking covered with foil is an important step. It traps the steam and allows the casserole to heat through evenly without the top drying out or burning before the inside is hot and bubbly.
6. Refrigerator: Once cooled, cover the baking dish tightly or transfer leftovers to an airtight container. Store in the refrigerator for up to 5 days. The sauce will thicken considerably as it chills.
7. Reheating: To reheat, you can microwave individual portions. For best results, add a splash of milk or broth when reheating on the stovetop or in the oven to bring back some of the creamy texture.
