Ingredients You’ll Need

• 500g beef mince (15-20% fat for flavour)
• 1 large onion, finely diced
• 3 cloves of garlic, minced
• 1 large red bell pepper, diced into 1cm pieces
• 2 tablespoons tomato purée
• 400g can of chopped tomatoes
• 300ml beef stock (use a good-quality stock for depth)
• 1 tablespoon smoked paprika
• 2 teaspoons ground cumin
• 1 teaspoon dried oregano
• ½ teaspoon cayenne pepper (adjust to your heat preference)
• Salt and freshly ground black pepper, to taste
• 250g dried macaroni pasta (or another short pasta like conchiglie)
• 200g mature cheddar cheese, grated
• 100g mozzarella, grated (for that glorious, stretchy top)
• Small handful of fresh parsley or coriander, roughly chopped, for finishing

Tip: Use a block of cheddar and grate it yourself — pre-grated cheese contains anti-caking agents that prevent it from melting as smoothly, and you want that silky, cohesive cheese layer on top.

How to Make One-Pan Chili Mac Bake

1. Brown the mince with patience: Warm a large, ovenproof skillet or heavy-based pan over a medium-high heat. Add the beef mince, breaking it apart with a wooden spoon. Let it sit undisturbed for 3-4 minutes — you want to see the underside turn a deep, rich brown before stirring. The sound should be a gentle, steady sizzle, and the smell will shift from raw to toasty and savoury. Once browned, use a slotted spoon to transfer the mince to a plate, leaving the rendered fat in the pan.
2. Soften the aromatics: Reduce the heat to medium. Add the diced onion to the pan and cook for 5-6 minutes, stirring occasionally, until it becomes translucent and begins to catch a little colour at the edges. The kitchen will fill with a sweet, fragrant note. Stir in the minced garlic and diced red pepper, and cook for a further 2 minutes, until the pepper has softened and you can smell the garlic mellowing.
3. Bloom the spices: Add the tomato purée to the pan and stir for 1 minute — it will darken and release a deeper, concentrated tomato aroma. Then sprinkle over the smoked paprika, ground cumin, dried oregano, and cayenne pepper. Stir constantly for 30 seconds. This toasts the spices, making them fragrant and unlocking their full flavour. You’ll notice the colour of the mixture deepen to a warm, rusty red.
4. Build the sauce: Return the browned mince to the pan. Pour in the chopped tomatoes and beef stock, then stir everything together, scraping the bottom of the pan to lift any browned bits. Season with salt and pepper. Let the mixture come to a gentle simmer — you should see lazy bubbles breaking the surface, not a furious boil. The liquid will look thin and soupy at this stage, which is exactly right.
5. Cook the pasta in the sauce: Stir the dried macaroni directly into the simmering sauce. Cover the pan with a lid (or a tight sheet of foil) and reduce the heat to low. Let it cook for 12-14 minutes, stirring once halfway through to prevent the pasta from sticking. The texture of the sauce will thicken noticeably as the pasta releases its starch, and the macaroni will become tender but still have a slight bite at the centre. The smell at this stage is deeply comforting — rich, tomatoey, and smoky.
6. Finish with cheese and bake: Preheat your oven’s grill to a high setting. Remove the lid from the pan — the sauce should be coating the pasta generously, not swimming in liquid. Sprinkle the grated cheddar and mozzarella evenly over the top, creating a blanket of cheese. Place the pan under the grill for 4-6 minutes, watching carefully. You are looking for the cheese to melt, bubble, and turn golden-brown in patches — the surface should have a few darker, blistered spots for texture. The sound of the cheese bubbling under the grill is a signal that it is nearly ready. Remove from the oven and let it rest on the stovetop for 5 minutes before serving.
7. Serve with a flourish: Scatter the chopped fresh parsley or coriander over the top. The contrast of the bright green herbs against the rich, golden cheese is a visual promise of the warmth within. Scoop into bowls while it is still hot and stretchy.

Tips From My Kitchen

• Don’t rush the browning of the mince: This is the single most important step for flavour. If you crowd the pan or stir too often, the meat will steam rather than brown, and you lose that deep, caramelised taste. Let it sit, let it sizzle, and only stir once the underside is properly dark. Friends always ask me for this recipe after trying it at dinner parties, and I credit this step for the difference.
• Use a heavy-based, ovenproof pan: A cast-iron skillet or a stainless-steel pan with a metal handle is ideal. It distributes heat evenly for browning, and it can go straight under the grill. If your pan has a plastic or wooden handle, wrap it in several layers of foil to protect it, or transfer the mixture to a baking dish before adding the cheese.
• Adjust the liquid based on your pasta: Different shapes and brands of pasta absorb liquid at slightly different rates. If the sauce looks too thick before you add the pasta, stir in an extra 50ml of stock. If it looks too thin after the pasta has cooked, uncover the pan and let it simmer for a minute or two to reduce.
• Grate your own cheese from a block: As mentioned in the ingredients tip, pre-shredded cheese is coated in starch to stop it clumping, which also stops it from melting into a smooth, cohesive layer. For that glossy, bubbly top, grating your own is non-negotiable.
• Let the dish rest after baking: The 5-minute rest after grilling allows the sauce to settle and thicken further. If you serve it immediately, the cheese layer might slide off, and the sauce will be too runny. Patience here rewards you with a cleaner serve and a more cohesive texture.

Common Mistakes to Avoid

• Overcrowding the pan: If your pan is too small, the mince will pile up and steam instead of browning. Use a pan that is at least 30cm in diameter, or cook the mince in two batches if necessary. A proper brown is the foundation of the entire dish.
• Wrong temperature: For browning the mince, you need a medium-high heat that is hot enough to create a crust but not so hot that the fat burns and turns bitter. A good test: a drop of water should sizzle and evaporate instantly when it hits the pan. For simmering the sauce, keep it on a low heat — a vigorous boil will break down the pasta and make it mushy.
• Skipping the rest time: It is tempting to dive straight in, but the rest is not optional. It allows the starch from the pasta to fully absorb into the sauce, creating a thick, luscious consistency. Without it, you end up with a soupy bottom layer and a dry top.

Delicious Variations to Try

• Spicy Version: Add a finely chopped red chilli (seeds included for extra heat) along with the garlic and pepper. You can also stir in a teaspoon of chipotle paste with the tomato purée for a smoky, fiery depth that lingers.
• Vegetarian/Vegan Option: Replace the beef mince with 400g of cooked lentils (brown or green work best) or a plant-based mince alternative. Use a vegetable stock instead of beef stock, and swap the cheddar and mozzarella for a good-quality vegan melting cheese. The cooking time remains largely the same, though plant-based mince may require a slightly shorter simmer.
• Different Protein: Swap the beef mince for an equal weight of turkey mince or lamb mince. Turkey mince is leaner, so add a tablespoon of olive oil when browning to prevent it from drying out. Lamb mince brings a richer, more gamey flavour that pairs beautifully with the cumin and smoked paprika.
