Meatless Monday: Pumpkin mac and cheese

This autumnal pasta is creamy and rich thanks to the roasted squash, a little unctuous thanks to the cooked onions, and gloriously herby thanks to the fresh sage.

Take me to the recipe!

This mac and cheese is warming, cheesy, and chock full of veggies. It also works as dinner or lunch (or both!). I’ve made this with some sausage on the side for an even heartier meal, but it’s very filling on its own.

A couple of notes:
- I use half roasted squash and half pumpkin (butternut or acorn squash is my favorite, but you could use kobocha or delicata) because I don’t always love straight pumpkin pasta sauces. There is something heavy and somehow both flavorless and overwhelming about a sauce made with just pumpkin.
- The most time consuming part of this recipe is cooking the onions. A longer, slower cook yields much better flavor that significantly improves the final dish. I recommend taking the time.
- This recipe makes twice as much sauce as you need for a pound of pasta. You can either freeze half, or make two boxes of pasta for a large family. We’ve found that using 1 box of pasta and freezing half of the sauce yields one dinner for the four of us and some leftovers for lunch the next day.

Pumpkin mac and cheese

Time: 45 minutes, mostly active
Yield: 4 adult-sized dinner servings, 6 kid-sized dinner servings, or more if you’re serving this for lunch

2 Tbsp olive oil, butter, ghee, or your fat of choice
1 large onion, sliced thinly
2 large cloves garlic, diced
10 large sage leaves, minced
2/3 cup pumpkin puree
1 cup squash, roasted
½ tsp kosher salt
1/2 cup milk, or more, to create desired consistency
½ cup gruyere, shredded
½ cup cheddar cheese, shredded
¼ cup grated parmesan
1 lb pasta
1/2 cup reserved pasta water

Preheat the oven to 425. Cut your squash in half lengthwise and place cut side down on a parchment-covered baking sheet. Bake until fork tender, about 20-30 minutes.  

Bring a large stock pot of salted water to a boil. Cook your pasta according to package directions (towards the end of cooking your onions). Reserve 1/2 cup of pasta cooking water.

Heat a large sauté pan with the cooking oil over medium heat. Turn the heat down slightly and add the thinly sliced onions. Cook, stirring often, until caramelized, about 25- 30 minutes.

Add the garlic and sage to the pan with the onions and cook until fragrant, about 2-3 minutes. Remove from the heat.

In a blender or food processor, combine the cooked onions, garlic, sage, squash, pumpkin, salt, and cheese. Blend on high. Slowly add the milk until you’ve reached your desired consistency.* Scrape down the sides as needed.

Pour about 1/2 of the sauce into a large container for another time.

Drain your pasta, but reserve ½ cup of the pasta water. Put the pasta back into the pasta pot, top with ½ of the sauce, and thin out as needed with the reserved pasta water. Taste for seasoning and add salt and pepper as needed.

*The amount of milk you’ll need depends largely on your squash. Some squash have more water in them, so you’ll need less milk. Start with ¼ cup and add more as needed.
