There’s something particularly fun about eating pumpkin at this time of year, even if it comes from a can. It’s not as popular here in the UK as it is elsewhere, but I love the extra dimension the pumpkin brings to this cheesy pasta. This one pot pumpkin mac and cheese is rich, comforting and full of autumnal flavour.

And the best part? It’s a one pot meal! The pasta cooks right in the sauce, so there’s no need to boil it separately and wash up another pan. As it cooks, the pasta soaks up all the delicious flavour from the creamy pumpkin sauce, making every bite super tasty. It’s easy, cosy and requires minimal washing up – basically everything I want from a weeknight dinner.

🥗 Ingredients

Here’s what you’ll need to make this cheesy pumpkin pasta.

Detailed ingredient quantities (in both US and UK recipe formats) can be found in the printable recipe card.

  • canned pumpkin. This can sometimes be hard to find in the UK, but if needed you can purchase it on Amazon. Make sure you use 100% pumpkin – nothing sweetened or spiced.
  • macaroni or similar small pasta shape. Larger pasta will also work, but will take a little longer to cook. If you’re using a larger pasta shape, make sure you measure the quantity by weight, not by cups, as this will differ from the small macaroni.
  • milk
  • vegetable stock – I used a stock cube dissolved in water, but liquid stock will also work fine.
  • smoked paprika, garlic and dried thyme – to add plenty of warm, autumnal flavour to the sauce.
  • cheddar cheese – ideally freshly grated mature (or extra mature!) cheddar.

📝 Note: If you have a fresh pumpkin that you’d like to use instead of canned, you can microwave or roast the pumpkin, puree it thoroughly, then proceed with the recipe as written.

🔪 Equipment You’ll Need

For this one pot pasta recipe, I used my favourite enormous Le Creuset pot. I’ve been looking for any excuse to use it recently (see my creamy vegetable stew!) – it’s just so satisfying to see such a beautiful big pot of food bubbling away on the hob.

Le Creuset casserole dishes are admittedly pretty expensive (mine was a very generous gift a long time ago and I don’t think I would have bought one myself, purely for price reasons – though I do absolutely love having one). Luckily, you can also buy very similar pots that are a much more budget-friendly and have great reviews:

Recipe by: Becca Heyes

Ingredients

  • 1 Tablespoon butter
  • 1 teaspoon minced garlic
  • 1 teaspoon smoked paprika
  • 1 teaspoon dried thyme or sage
  • 450 g (~ 1 lb / ~ 3 cups) uncooked macaroni
  • 1 can (425 g / 15 oz / ~ 1 3/4 cups) plain unsweetened pumpkin
  • 625 ml (~ 2 1/2 cups) milk
  • 500 ml (~ 2 cups) vegetable stock
  • 300 g mature cheddar cheese, grated (~ 3 cups when grated)
  • Salt and black pepper, to taste.

Instructions
 

  • Melt the butter in a large pot, and add the minced garlic, smoked paprika and dried thyme. Cook for a couple of minutes over a medium heat, until fragrant.
  • Add the next 4 ingredients (uncooked pasta, canned pumpkin, milk, vegetable stock), and mix well to combine. Bring to a simmer, stirring regularly to stop the pasta from sticking.

  • Turn the heat down low, and add the grated cheese. Mix to combine, and allow the cheese to melt into the sauce. Season to taste with salt and black pepper (I like lots of pepper!). If you like, you can sprinkle a little extra cheese on top, and allow it to melt (or even place it under the grill / broiler for a minute or two) to create an extra little cheesy topping. I also garnished with some semi-dried parsley.
