Creating Butternut Squash Mac and Cheese with Thyme Breadcrumbs is a blend of straightforward steps. Follow these easy instructions:

1. Preheat Oven: Preheat your oven to 350°F (175°C).

2. Cook Pasta: In a large pot of salted boiling water, cook the elbow macaroni according to package directions. Drain and set aside.

3. Prepare Butternut Squash: In a large baking dish, toss the diced butternut squash with olive oil, salt, and pepper. Roast in the preheated oven for 25-30 minutes or until tender.

4. Sauté Onions and Garlic: In a large skillet over medium heat, add a splash of olive oil. Sauté the diced onion until translucent, about 5 minutes. Add minced garlic and thyme, cooking for about 1 minute more.

5. Blend Sauce: In a blender, combine roasted butternut squash, sautéed onions, garlic, milk, and vegetable broth. Blend until smooth and creamy.

6. Combine Cheese with Sauce: Transfer the blended mixture to a pot over low heat. Gradually add your cheddar and Parmesan cheeses, stirring constantly until melted and smooth. Add cooked pasta, mixing well to ensure the noodles are coated.

7. Prepare Breadcrumb Topping: In a small bowl, mix breadcrumbs with melted butter and a pinch of salt. If using fresh thyme, add some to the breadcrumbs for added flavor.

8. Assemble: Pour the mac and cheese into a greased baking dish. Evenly sprinkle the breadcrumb mixture on top.

9. Bake: Place the baking dish in the oven and bake for about 15-20 minutes or until the top is golden brown and crispy.

10. Cool and Serve: Remove from the oven and let it sit for a few minutes before digging in. This allows the cheese to set slightly for easier serving.
