Low-Fat Mac and Cheese (Under 6 g of Fat)

Low-Fat Mac and Cheese (Under 6 g of Fat)

A restaurant portion of macaroni cheese runs to 25–35 g of fat, and a boxed mix is not much kinder. Nearly all of it comes from butter, whole milk and a mountain of mild cheese doing the work that a little sharp cheese and a thickened sauce can do on their own. This version comes out at 5.4 g of fat a serving, still pours off the spoon, and still tastes like the thing you actually wanted.

Why This Version Works

• No butter roux. Cornflour whisked into cold milk thickens just as reliably and brings no fat with it.
• Butternut squash does the clinging. Blended smooth, it gives the sauce body and the colour people expect from macaroni cheese.
• Sharp cheese, less of it. Fifty grams of extra-mature cheddar tastes louder than 150 g of mild, so you pay for flavour instead of volume.
• Seasoned properly. Mustard, nutmeg and white pepper replace the richness you took out. Without them a low-fat sauce tastes flat, and most versions fail here.

Ingredients

• 225 g (8 oz) dried macaroni or small shells
• 300 g butternut squash, peeled and cubed (about 2 cups)
• 400 ml skimmed milk
• 2 tbsp cornflour (cornstarch)
• 50 g extra-mature (sharp) cheddar, finely grated
• 20 g parmesan, finely grated
• 1 tsp Dijon mustard
• 1/2 tsp onion powder
• 1/4 tsp ground nutmeg
• Salt and white pepper
• 2 tbsp dried breadcrumbs, for the top (optional)
• Cooking spray

Instructions

1. Boil the squash in a small pan of water for 12–15 minutes, until it collapses under a fork. Drain well and blend to a completely smooth purée. Lumps here become lumps in the sauce.
2. Cook the pasta in salted water one minute short of the packet time. Drain and keep back a mugful of the cooking water.
3. Whisk the cornflour into 100 ml of the cold milk until no lumps remain, then pour it into a pan with the rest of the milk. Heat gently, whisking, until it thickens to the texture of single cream, about 4 minutes.
4. Off the heat, stir in the squash purée, mustard, onion powder and nutmeg. Now add both cheeses and stir until they melt. Adding cheese off the heat keeps the sauce smooth instead of grainy.
5. Season with salt and plenty of white pepper — a low-fat sauce needs more seasoning than a buttery one, and this is the step people skip.
6. Fold in the pasta, loosening with the reserved cooking water until it pours rather than clumps. It should look slightly too loose; it tightens as it stands.
7. To finish under the grill: tip into a misted dish, scatter with breadcrumbs, and grill 3–4 minutes until spotted brown. To serve straight away, skip this and eat it while it is at its creamiest.

Variations

• Cauliflower instead of squash. Same method, paler sauce, more neutral flavour.
• Add protein. Stir through shredded poached chicken breast or a tin of drained tuna in spring water; both add almost no fat.
• Green version. Fold in a large handful of spinach or frozen peas with the pasta.
• Sharper still. A teaspoon of cider vinegar at the end lifts the whole dish and costs nothing.

Storing and Leftovers

Keeps three days covered in the fridge. It sets firm when cold — that is the cornflour, not a mistake. Reheat in a pan or microwave with two tablespoons of milk per portion, stirring once or twice, and it loosens back to its original texture. It freezes for two months, though the pasta softens a little on thawing, so freeze it slightly undercooked if you plan ahead.

Questions People Ask

Why squash instead of more cheese?

Because fat is what makes a cheese sauce cling, and squash does that job for almost none. It also carries the orange colour people expect, which matters more than anyone admits. Cauliflower works the same way if you would rather the flavour stayed neutral.

Can I use pre-grated cheese?

You can, but pre-grated cheese is coated in starch to stop it clumping and it melts grudgingly. Grating a small block of the sharpest cheddar you can find gives you more flavour per gram, which is the whole trick here.

Will this reheat?

Yes, better than most low-fat pasta. Reheat gently with a splash of milk and stir — the cornflour sauce comes back together. Microwaving it dry is what makes it rubbery.
