Ingredients + Inspiration

This recipe is inspired by all the cozy feels that come with autumn. There’s nothing like a hearty, creamy, stick-to-your-ribs recipe to get you through the darker, rainy days, am I right?
The pumpkin cream sauce for our Baked Vegan Pumpkin Mac & Cheese is a simple, but flavor-packed blend of cashews, pumpkin puree, olive oil, and spices. The buttery sourdough breadcrumbs on top are technically optional, but trust me when I say they take the dish to the next level! Plus, they’re infused with fragrant rosemary that packs loads of fall flavor 🙂
How to Make No-Boil Baked Pumpkin Mac & Cheese

I know how much you all love the dump-and-bake recipes on the blog, and I’ve got another favorite for you to add to this list! While this recipe takes about an hour until it’s ready to enjoy, it only needs 10 minutes of prep work—the remaining time is in the oven. All you need to do is:
- Blend the pumpkin “cheese” sauce until smooth & creamy.
- Place the diced pumpkin, pasta, and shallot in a casserole dish, pour the sauce over then cover and bake.
- Add the sourdough to the oven on a separate baking tray and bake until crisp & golden. In a food processor, pulse with rosemary, oil, salt, and pepper to make breadcrumbs.
- Spread the breadcrumbs evenly over the casserole and bake until golden and fragrant.
- Transfer to serving dishes and enjoy!

Enjoy this creamy, fall-inspired pumpkin mac & cheese anytime you’re craving something comforting! A cozy dish like this is perfect for lunch, dinner, or to bring along to a get-together this season 🙂 It’s great on its own, or you can pair it with more fall-flavored sides like these Pumpkin Cornbread Muffins or this Fall Vegetable Salad with Smoky Tempeh!

Baked Vegan Pumpkin Mac & Cheese
Ingredients
For the Pumpkin Cream Sauce:
- 3/4 cup cashews, soaked in water overnight*
- 1 cup pumpkin puree
- 3 cloves garlic
- 2 tablespoons olive oil
- 1/4 cup nutritional yeast
- 1/4 teaspoon ground nutmeg
- 1 1/2 teaspoons sea salt
- 4 1/4 cups water
For the Pasta:
- 12 ounces pasta, gluten-free if necessary*
- 1 shallot finely diced
- 2 cups diced pumpkin; see notes for substitutions
For the Breadcrumbs:
- 3.5 ounces sourdough bread
- 2 tablespoons olive oil
- 1/2 tablespoon fresh rosemary roughly chopped
- 1/4 teaspoon salt
- black pepper to taste
Instructions
- Prep: preheat the oven to 425F and set a 9×13″ casserole pan aside.
- Blend: add the soaked and drained cashews, pumpkin puree, garlic, olive oil, nutritional yeast, nutmeg, salt, and water to a high-speed blender. Blend on high for 45-60 seconds, until the cashews completely dissolve and you are left with a smooth and creamy sauce.
- Mix: add the pasta, pumpkin, and shallot to the casserole dish and mix until evenly distributed. Pour the sauce over the casserole, then use a spatula or spoon to press everything down evenly into the sauce, especially the pasta noodles.
- Bake: Cover the dish tightly with aluminum foil (or parchment paper, followed by aluminum foil) and bake in the middle rack of the oven for 45 minutes.
- Breadcrumbs: place the sourdough on separate baking tray and bake alongside the casserole for 10-20 minutes, until dry and golden; bake time will depend on the size of your bread. Roughly break up the bread with your hands, then transfer it to a food processor along with the chopped rosemary, salt, and pepper to taste. Pulse until a fine but crumbly texture forms. Drizzle the oil over the breadcrumbs, then pulse again until evenly distributed. Transfer the breadcrumbs to a small bowl and set aside.
- Make it Crispy: after 45 minutes, remove the casserole dish from the oven and stir well to evenly distribute the sauce. Cover the pasta evenly with breadcrumbs, then return to the oven and bake for an additional 7-10 minutes. (See notes for cooking time without breadcrumbs)
- Serve + Store: serve warm; leftovers can be stored in the fridge and are best eaten within 5 days
Recipe Notes
- Cashews: If you forget to soak your cashews ahead of time, you can (1) cover them in boiling water and let sit for 20 minutes, or (2) cover them with water and microwave for 3 minutes, then let sit for 3-5 minutes before draining.
- Pasta: I recommend using short pasta shapes (as opposed to noodles) for this recipe. If you are using gluten-free pasta, corn & rice varieties tend to hold up better without breaking.
- Pumpkin: cubed pumpkin can be replaced with peeled sweet potato, butternut squash, or kabocha squash.
- No Breadcrumbs: bake the casserole for 45 min only, but let sit 5 minutes covered before mixing and serving
- Oil-Free: you can omit the oil from the sauce if you’d like, but it will not be as smooth. Same with the breadcrumbs; they will not get as golden, but will still be tasty!
Made this tonight and it came out amazing! I used butternut squash instead of pumpkin. I will definitely make this again. Thank you!
Yay! Thank you, Heather! ♥
Delicious and comforting on a cold and rainy day. I used butternut squash, gluten free brown rice macaroni and added a can of cannelini beans.
Great additions, thank you for sharing!
This is excellent! Thank you for publishing it it. I made it with GF rice-lentil pasta, used a can of pumpkin and adjusted the water and it was yummy.
That’s great, Gail! Thank you for making the recipe.
This has become a family favourite! We love it!
Happy to hear that, Allison!
Hi! Can’t wait to make this. Any suggestions on what to use instead of nutritional yeast? Thank you!
There is no true substitute for nutritional yeast, though you could try using some shredded plant-based cheese instead. Let me know if you try this!
Hi Caitlin! I love your recipes, but I’m allergic to nuts. Any other way I can make a creamy sauce without cashews? Thank you so much!
Raw sunflower seeds can be substituted for cashews in a 1:1 replacement. You will need to soak your sunflower seeds similarly to your cashews. This works very well in savory recipes like sauces and dips.
I don’t have a food processor, how else can I make the breadcrumbs or what substitutions can I make? I’m dying to try this. Ty!
You can use a blender or even a box grater.
Made this for dinner tonight and it was amazing. Definitely getting added to the rotation! I used butternut squash purée and cubed butternut squash, some of the cubes aren’t quite soft enough for my liking but I don’t think I cubed them small enough so I know next time they’ll be perfect. I used Ronzoni gf rotini pasta and it held up well. I also used Ian’s gf panko for the breadcrumbs and only used half of the breadcrumb recipe to top. 9/10! (Will be 10/10 next time with smaller cubes 🙂 )
It’s so yummy! My whole family enjoys it!
So glad you all enjoy it, Celine!
I was skeptical that this could turn out so good, but I don’t mind being wrong! This recipe is phenomenal – my partner and I loved it! Bonus points for it being easy to make but yielding such a surprisingly creamy and flavorful dish! We ended up eating this over a few days as leftovers and still enjoyed it every time. The only substitution we made was replacing the cubed pumpkin with sweet potato since it’s easier and more affordable.
Thanks, Nancy! So glad to hear you enjoyed it. 🙂
So delicious! I made this for a vegan Friendsgiving and it was incredible. The breadcrumbs just make it amazing!
Glad you loved it, Vanessa! 🙂
Thank you, Vanessa!
So easy to make, super yummy, and perfect for meal prep! Made it at the start of the week and my partner and I didn’t get tired of it even though we ate it multiple days in a row, which made it a total success!
Thanks, Quinn! So glad to hear you enjoyed it. 😊
