Yield: 4 servings
Cuisine: Asian Fusion
Ingredients: Butternut squash; Cauliflower; Pasta; Olive oil; Onion; Garlic; White miso; Milk; Grated cheese; Dijon mustard; Nutmeg; Sage; Pumpkin seeds

A holiday pasta bake does not need butter roux and a flood of cream. This butternut squash and cauliflower bake uses the squash and cauliflower to build a thick, creamy base, with cheese doing flavor duty rather than volume — about 420 calories a serving. A small spoon of white miso deepens the savory layer beyond a standard mac and cheese, without adding weight. Six illustrated steps, you can assemble it ahead and chill, then straight into the oven on the day — a crowd-pleasing healthy mac and cheese that still reads as a low calorie pasta bake.

Step by Step

How to make it

Roast the squash and cauliflower

Toss 400 g cubed butternut and 300 g cauliflower with 1 tbsp olive oil and roast at 200C / 400F for 20 minutes until soft and lightly caramelized. Roasting concentrates their sweetness so the bake tastes rich without any cream.

Blend the sauce base

Blend the roasted squash with 200 ml milk, 1 tbsp white miso, 1 tsp Dijon and a pinch of nutmeg until silky. The squash and cauliflower become the thick, creamy base — the miso adds a salty-savory depth a plain mac and cheese never reaches.

Cook pasta and fold

Boil 250 g pasta to al dente, then fold it with the roasted cauliflower and the squash-miso sauce in a baking dish. Keep a little pasta water to loosen the sauce if it thickens as it sits.

Add cheese, light not heavy

Stir in 40 g of the grated cheese so it melts into the sauce, then scatter the remaining 20 g on top. Cheese here is for flavor, not volume — that is how the bake stays around 420 kcal instead of the usual 700-plus.

Top and bake

Scatter a few sage leaves and pumpkin seeds over the top and bake at 200C / 400F for 18 to 20 minutes until the edges bubble and the cheese turns patchy gold. The sage and seeds add texture and a festive look without extra weight.

Make ahead and finish

Assemble the whole dish up to a day ahead, cover and chill, then bake straight from cold adding 5 minutes. Serve as a vegetarian holiday main or a side — either way it is a lighter, miso-laced take on comfort food.

Tips & Swaps

Roast, do not boil the squash

Roasting caramelizes the squash so the sauce tastes sweet and rich; boiling makes it watery.

Cheese for flavor only

Stir most of the cheese into the sauce and save a light layer for the top — that keeps it around 420 kcal.

Make it vegan

Swap the cheese for a nutritional-yeast blend and use oat milk; the miso and roasted squash still carry the savory depth.

FAQ

Questions, Answered

Can I make the butternut squash pasta bake ahead of time?

Yes. Assemble the whole bake up to a day ahead, cover and chill, then bake straight from cold with 5 extra minutes. It is an ideal make-ahead Christmas side dish for a busy holiday kitchen.

Is this pasta bake vegetarian?

Yes, with cheese and no meat. Use vegetarian hard cheese and oat milk and it stays fully vegetarian — a solid vegetarian Christmas pasta bake option.

How does it stay creamy without heavy cream?

Roasted butternut squash and cauliflower are blended into the sauce, so the creaminess comes from vegetables, not cream. A spoon of white miso adds savory depth, keeping it around 420 kcal a serving.

Can I serve it as a main or a side?

Either. It works as a vegetarian holiday main or a lighter side next to roast meat — the recipe is built to do both, so you can place it wherever the table needs it.
