Ingredients You’ll Need

• 500g macaroni pasta
• 1 medium butternut squash (about 800g), peeled, seeded, and diced into 1cm cubes
• 2 tablespoons olive oil
• 1 large onion, finely chopped
• 3 cloves garlic, minced
• 2 tablespoons fresh sage leaves, finely chopped (or 1 tablespoon dried sage)
• 500ml chicken or vegetable stock
• 300ml double cream
• 200g grated cheddar cheese
• 100g grated Parmesan cheese
• 1 teaspoon salt
• ½ teaspoon black pepper
• ½ teaspoon ground nutmeg
• 50g breadcrumbs (optional, for topping)

Tip: If you’re short on time, buy pre-chopped butternut squash from the supermarket — it saves a good 10 minutes of peeling and dicing, and the texture stays exactly the same.

How to Make Butternut Squash and Sage Macaroni Bake

1. Preheat and prep: Preheat your oven to 200°C (180°C fan). Bring a large pot of salted water to a rolling boil — you’ll know it’s ready when the surface is bubbling vigorously and steam rises steadily. Add the macaroni and cook for 2 minutes less than the package directions (it will finish cooking in the oven). Drain the pasta, reserving about 100ml of the starchy pasta water. You’ll see the pasta is still quite firm and pale in the centre.
2. Sauté the aromatics: In the same large pot, heat the olive oil over medium heat until it shimmers and smells nutty. Add the chopped onion and cook for 4-5 minutes, stirring occasionally, until the onion turns translucent and softens — you’ll notice it becomes glossy and releases a sweet, savoury aroma. Stir in the minced garlic and chopped sage, cooking for another minute until the garlic is fragrant but not browned.
3. Cook the squash: Add the diced butternut squash to the pot along with the stock. Bring the mixture to a simmer — you’ll see small bubbles breaking the surface and the stock will look slightly cloudy. Reduce the heat to low, cover the pot, and let it cook for 10-12 minutes. The squash is ready when you can easily pierce a cube with a fork and it feels tender but not mushy; the stock will have reduced by about a third and smell sweet and earthy.
4. Create the creamy sauce: Remove the pot from the heat. Using a potato masher or a stick blender, mash or blend the squash mixture until smooth — you’re aiming for a thick, velvety purée with no lumps, the colour of a deep sunset. Stir in the double cream, grated cheddar, half the Parmesan, salt, pepper, and nutmeg. The sauce will look glossy and smell rich and cheesy. If it seems too thick, add a splash of the reserved pasta water until it reaches a pourable consistency.
5. Combine with pasta: Add the drained macaroni to the sauce and stir thoroughly until every piece of pasta is coated — you’ll see the sauce clinging to the ridges of the macaroni, creating a uniform, golden mixture. Taste and adjust seasoning if needed.
6. Assemble and bake: Transfer the mixture to a lightly greased 23x33cm baking dish. Sprinkle the remaining Parmesan and the breadcrumbs evenly over the top. Bake for 15-18 minutes, until the top is golden brown and bubbling around the edges — you’ll hear a gentle sizzle, and the breadcrumbs will look crisp and toasted. Let it rest for 5 minutes before serving; the sauce will thicken slightly as it cools.

Tips From My Kitchen

• Undercook the pasta deliberately: Because the bake goes into the oven, the pasta continues to absorb liquid and cook. If you boil it until fully tender, it will turn mushy after baking. Cooking it 2 minutes under al dente ensures it finishes perfectly in the oven, with a slight bite that holds up well.
• Use fresh sage for the best flavour: Dried sage works in a pinch, but fresh sage leaves have a more delicate, peppery aroma that mellows beautifully as it cooks. Fry the leaves briefly in the oil before adding the onion to release their essential oils — you’ll smell a distinct pine-like fragrance that signals they’re ready.
• Don’t skip the nutmeg: Nutmeg might seem optional, but it acts as a subtle bridge between the sweet squash and the savoury cheese. Just half a teaspoon lifts the entire dish without being noticeable on its own. Grate it fresh if you can — the pre-ground stuff is fine, but fresh nutmeg has a warmer, more aromatic character.
• Make it ahead for stress-free evenings: Assemble the bake completely (without the breadcrumb topping) up to 24 hours in advance. Cover tightly with foil and refrigerate. When you’re ready, add the breadcrumbs and bake straight from the fridge, adding an extra 5-7 minutes to the cooking time. The texture remains creamy and delicious.
• Freeze individual portions: This bake freezes exceptionally well. Portion it into individual oven-safe containers, cool completely, and freeze for up to 3 months. To reheat, thaw overnight in the fridge and bake at 180°C for 20 minutes, or microwave individual portions for 3-4 minutes. The sauce might separate slightly, but a quick stir brings it back together.

Delicious Variations to Try

• Spicy Version: Add 1 teaspoon of red pepper flakes or a finely chopped fresh red chilli when you sauté the onion. The heat cuts through the creamy squash and cheese, giving the dish a lovely warmth that pairs wonderfully with the sage.
• Vegetarian/Vegan Option: Use vegetable stock and replace the double cream with a can of full-fat coconut milk or a cup of cashew cream. Swap the cheddar and Parmesan for a good vegan melting cheese — the squash purée is naturally creamy, so you won’t miss the dairy.
• Different Protein: Stir in 300g of shredded rotisserie chicken or cooked, crumbled turkey mince along with the pasta. The mild flavour of poultry lets the squash and sage shine, while adding extra protein for a more filling meal. For a heartier option, try diced and pan-fried chicken thighs.

What to Serve With Butternut Squash and Sage Macaroni Bake

• A crisp green salad with a simple lemon vinaigrette to cut through the richness
• Steamed green beans or tenderstem broccoli, lightly seasoned with salt
• Garlic bread or crusty sourdough to mop up any extra sauce from the dish
• A side of roasted cherry tomatoes, which add a burst of acidity

Notes

For a vegetarian version, use vegetable stock. The pasta is cooked 2 minutes less than package directions to ensure it doesn’t become mushy after baking. Let the dish rest for 5 minutes before serving for best texture.
