Cozy Weekend Project: Butternut Squash and Sage Macaroni Bake

There are certain weekends that call for a project, something that fills the house with a gentle, earthy perfume long before you sit down to eat. This butternut squash and sage macaroni bake is that kind of cooking. It asks for a bit of time, a willingness to let the squash caramelise slowly, and the simple pleasure of stirring a creamy, sage-flecked sauce. It’s the sort of dish you build, layer upon layer, until the kitchen feels warm and the promise of that golden, bubbling top is the only thing on your mind.

Why You’ll Love This Butternut Squash and Sage Macaroni Bake

• The aroma alone is worth it. The scent of sage leaves crackling in butter, mingling with the sweet, nutty fragrance of roasting squash, is the very definition of a slow, cosy weekend — much like our Cozy Weekend Chicken Divan with Aromatic Comfort.online/cozy-weekend-one-pan-chili-mac-bake/”>Cozy Weekend One-Pan Chili Mac Bake.
• Two textures in every bite. You get the creamy, soft interior of the pasta and sauce, contrasted with a gloriously crispy, golden crust of cheese and breadcrumbs. It’s a study in contrasts.
• It’s a complete meal in a dish. With the squash, pasta, and a rich, cheesy sauce, this bake is satisfying enough to stand on its own, needing only a simple green salad on the side.
• The flavour deepens overnight. I stumbled upon this combination by accident, and it’s been a hit ever since. The leftovers, if any remain, are even more flavourful the next day as the sage and squash meld together.
• It trains you to slow down. This isn’t a rushed weeknight dinner. It’s a deliberate, mindful process of roasting, stirring, and assembling. The kitchen becomes your sanctuary for an afternoon.

Ingredients You’ll Need

• 1 large butternut squash (about 1kg), peeled, seeded, and cut into 2cm cubes
• 3 tablespoons olive oil
• Salt and freshly ground black pepper
• 500g dried macaroni pasta
• 60g unsalted butter
• 1 large onion, finely chopped
• 3 cloves garlic, minced
• 20 fresh sage leaves, finely chopped, plus a few whole leaves for garnish
• 60g plain flour
• 900ml whole milk
• 200ml chicken or vegetable stock
• 250g mature cheddar cheese, grated
• 100g Parmesan cheese, finely grated
• 100g fresh breadcrumbs
• Pinch of freshly grated nutmeg

Tip: For the best flavour, use a block of mature cheddar and grate it yourself. Pre-grated cheeses often contain anti-caking agents that prevent the sauce from becoming as smooth and creamy as it should be.

How to Make Butternut Squash and Sage Macaroni Bake

1. Roast the squash. Preheat your oven to 200°C (180°C fan). Tumble the cubed butternut squash onto a large baking tray. Drizzle with the olive oil, season generously with salt and pepper, and toss to coat. Spread into a single layer. Roast for 25-30 minutes, until the edges are caramelised and the flesh is tender when pierced with a fork. The kitchen will fill with a sweet, nutty scent. Set aside to cool slightly.
2. Cook the pasta. While the squash roasts, bring a large pot of salted water to a rolling boil. Add the macaroni and cook for 2 minutes less than the package directions suggest. You want it quite al dente, as it will continue to cook in the oven. Drain it, reserving a cup of the pasta water, and set aside.
3. Infuse the butter with sage. In a large, heavy-based saucepan, melt the butter over a medium heat. Add the chopped onion and cook for 5-7 minutes, or until it becomes translucent and soft. You’ll hear a gentle sizzle. Add the minced garlic and the chopped sage, stirring for another minute until the garlic is fragrant and the sage releases its earthy, almost peppery aroma.
4. Make the roux. Sprinkle the flour over the onion and sage mixture. Stir continuously for 2 minutes, cooking the flour until it forms a pale, bubbling paste. This is your roux; it should smell nutty and look like wet sand. The colour will be a very light gold.
5. Build the sauce. Gradually pour in the milk, a little at a time, whisking constantly to prevent lumps. Once all the milk is incorporated, add the stock. Continue to whisk over a medium heat until the sauce thickens enough to coat the back of a spoon. This will take about 5-7 minutes. Listen for the change in sound as it thickens, from a sloshing to a gentle, slow bubble.
6. Finish the sauce. Remove the pan from the heat. Stir in the grated cheddar and half of the Parmesan cheese until they are fully melted and the sauce is silky. Grate in a pinch of nutmeg, then taste and adjust the seasoning with salt and pepper. The texture should be smooth and glossy.
7. Assemble the bake. Add the drained pasta and the roasted butternut squash to the sauce. Stir gently until everything is evenly coated. If the sauce seems a little thick, add a splash of the reserved pasta water to loosen it. The mixture should look creamy and inviting.
8. Top and bake. Pour the mixture into a 9×13 inch baking dish. In a small bowl, combine the breadcrumbs with the remaining Parmesan cheese. Sprinkle this mixture evenly over the top. Dot with a few whole sage leaves for extra fragrance and visual appeal. Bake for 25-30 minutes, until the filling is bubbling around the edges and the top is a deep, crunchy golden brown. The sound of the bubbles breaking through the crust is the sound of success.
9. Rest and serve. Remove from the oven and allow the bake to rest for 10 minutes. This is crucial; it lets the sauce settle and firm up slightly, making it much easier to serve. The steam that rises as you cut into it will carry the final, perfect note of sage and nutty squash.

Tips From My Kitchen

• Don’t skip roasting the squash. Boiling or steaming the squash will make it watery and bland. Roasting concentrates its natural sugars, giving it a caramelised sweetness that is the backbone of this dish. The charred edges also add a lovely, complex flavour that you simply cannot get any other way.
• Undercook the pasta deliberately. This is the most common mistake. If you cook the pasta to al dente, it will become mushy after baking in the sauce. By cooking it for 2 minutes less, you ensure it remains firm and toothsome, offering a pleasant bite against the creamy sauce and soft squash.
• Use whole milk for the sauce. Semi-skimmed or skimmed milk will not create the same rich, velvety texture. The fat content in whole milk is essential for a stable, luscious béchamel that won’t split or become thin during baking. It’s the difference between a good bake and a transcendent one.
• Grate your own cheese from a block. I cannot stress this enough. Pre-shredded cheese is coated in starches and cellulose to prevent clumping, which also prevents it from melting smoothly. A freshly grated block of mature cheddar will melt into a silky, cohesive sauce with superior flavour.
• Let it rest before serving. I know the temptation to dig in immediately is strong, especially with that amazing smell filling the house. But if you serve it straight from the oven, the sauce will be runny and the layers will slide apart. Ten minutes of patience allows the starches to set, giving you clean, beautiful slices that hold their shape.
• Toast your breadcrumbs first for extra crunch. For an even crispier topping, toss the breadcrumbs with a little melted butter or olive oil and toast them in a dry frying pan for 2-3 minutes before sprinkling them on the bake. They will stay crunchy rather than absorbing moisture from the sauce.

Equipment You’ll Need

• 9×13 inch baking dish
• Aluminium foil (for covering if the top browns too quickly)
• Mixing bowls (one large, one small)
• Sharp knife and a sturdy vegetable peeler
• Large baking tray
• Large heavy-based saucepan
• Large pot for pasta
• Whisk and a wooden spoon
• Box grater

Delicious Variations to Try

• Spicy Version: Add a pinch of dried chilli flakes or a finely chopped red chilli to the butter along with the garlic and sage. The gentle heat contrasts beautifully with the sweet squash and creamy sauce, adding a new layer of complexity.
• Vegetarian/Vegan Option: Use a high-quality vegetable stock and substitute the cheddar and Parmesan with a plant-based melting cheese and nutritional yeast. For the butter, use a good vegan block. The sauce will be slightly less rich, but still very satisfying, especially with the nutty flavour from the nutritional yeast.
• Different Protein: For a heartier meal, stir 300g of shredded, cooked chicken or turkey (leftover roast works wonderfully) into the sauce along with the pasta and squash. You could also add 200g of cooked, crumbled Italian sausage (pork or turkey) for a more robust, herby flavour.

What to Serve With Butternut Squash and Sage Macaroni Bake

• A crisp, simple green salad with a sharp lemon vinaigrette to cut through the richness of the bake.
• Steamed tenderstem broccoli or green beans, tossed with a little butter and salt.
• For a truly indulgent weekend, nothing else is needed. Just a glass of cold water and a quiet table.

Notes

Reserve pasta water to adjust sauce consistency if needed. Letting the bake rest for 10 minutes before serving helps it set for cleaner slices.
