Roasted butternut & mascarpone pasta sauce with mushrooms recipe with pumpkin seeds and crspy brown butter sage leaves

Roasted butternut and mascarpone make the most delicious and velvety creamy sauce to coat pasta. Serve this with pan-fried mushrooms, toasted pumpkin seeds, crispy sage and Parmesan for a cosy autumnal treat.

A refreshing change from the ubiquitous tomato or cream-based sauce varieties, this recipe is adapted from my first cookbook. I included fried bacon and crispy prosciutto in the original rendition.

Here, for the sake of keeping it vegetarian, I have topped it with toasted pumpkin seeds and crispy fried sage leaves. It is so delicious!

Why this roasted butternut and mascarpone sauce works?

This is one of my all-time favourite pasta recipes and I can just spoon the sauce right out of the pan.

Roasting the butternut until the edges are caramelised gives them a delicious and intense flavour. I cut the pieces quite small so as to maximise this.

Using a mix of mushrooms such as Portobello, porcini, shitake, and enoki gives this pasta sauce an amazing umami flavour which balances out the sweetness of the butternut sauce.

Pan-frying the mushrooms in butter and thyme adds an earthy nutty flavour.

Mascarpone is essentially triple cream so this adds an amazing richness and silky texture. Although quite a calorie intense, it’s worth every one of them as a special treat. Use anywhere from 150 – 200 grams. This will depend on the size of your butternut. 

Parmesan cheese adds a salty dimension and obviously incredible flavour. Add bacon or crisped-up prosciutto as per my original recipe and as per the instructions below for an even more savoury flavour.

I love to use roasted pumpkin seeds with this recipe to add delicious crunch. Pumpkin seeds and butternut squash go perfectly together.

Sage leaves fried in butter are one of my all-time favourite herb garnishes and is perfect with butternut squash in this recipe. Drizzle over some of the brown sage butter to take this pasta to another indulgent but very delicious level.

If you are adding bacon, I suggest cooking it until crispy and adding it right at the end. Mix half into the sauce and half scattered over the top for a lovely crunchy texture. Decorate with oven-baked shards of crispy prosciutto.

For the mushrooms, I use a mix of portobello, porcini and shiitake mushrooms because I love their slightly chewy texture and meaty flavour, but any mushrooms will work well.

How to make roasted butternut & mascarpone pasta sauce with mushrooms

First, cut the butternut into small pieces and toss in olive oil, salt and pepper. Scatter over a few sprigs of thyme (you can just add them in whole here) and roast in an oven that has been preheated to 200C/400F until the edges are starting to caramelise.

Slice and pan-fry the mushrooms with butter and thyme until brown on the edges.

Add the drained pasta to the sauce. If necessary add a splash of pasta cooking water to loosen, but there should be more than enough sauce.

Roasted butternut & mascarpone pasta sauce with mushrooms recipe with pumpkin seeds and crspy brown butter sage leaves
Prep Time:10 minutes
Cook Time:35 minutes

Ingredients

  • 1 medium butternut peeled and diced fairly small (about 4 heaped cups)
  • Olive oil for drizzling
  • Salt  & freshly ground black pepper
  • 150 gms-200gms mascarpone
  • 250 ml 1 cup vegetable or chicken stock
  • 30 gms butter
  • 300 gm mixed mushrooms of your choice such as shiitake porcini, enoki, Portobello, sliced
  • 1 stalk of fresh thyme and 2tsp of stripped thyme leaves
  • 300- 350 gms dried tagliatelle pasta or other long pasta of your choice
  • Freshly grated Parmesan to serve
  • Toasted pumpkin seeds to serve optional
  • Fried sage leaves to serve optional
  • Salt & black pepper

Instructions

  • Preheat the oven to 200°C/400F.  Place the butternut and garlic on a baking tray and drizzle with olive oil, coating well. Season with salt and pepper and bake for 25 to 30 minutes or until caramelised and tender.
  • Blend the butternut, mascarpone and stock in a food processor or blender until smooth. Adjust the seasoning.
  • Heat a non-stick frying pan with a little olive oil and sauté the mushrooms until they just start to caramelise (about 4 minutes). Add the thyme and cook for another minute or two.
  • Add the puréed butternut mixture to the mushrooms and stir through.
  • Cook the pasta in salted water until al dente and drain, reserving some of the cooking liquid. Add the cooked pasta to the butternut sauce and stir. If the sauce is a bit thick, add about 60ml of the pasta water to thin it out.
  • Serve with freshly grated Parmesan, roasted pumpkin seeds, and sage leaves fried in butter.

Notes

*To fry the sage, melt about 30 grams of butter in a small pan and fry 6 – 8 sage leaves until starting to crisp up. Remove from the butter with a slotted spoon and drain on kitchen paper. You can drizzle the brown sage butter over your pasta for extra deliciousness
*To roast pumpkin seeds, spread a handful of pumpkin seeds over a baking tray and roast in 200C/400F oven for a few minutes until they start to crackle and go brown on the edges. You can do this directly after you have roasted the butternut as the oven will be preheated.
