Ingredients for american mac and cheese recipe uk

British cheeses and simple pantry staples create this ultra-creamy mac and cheese masterpiece.

The cheeses are the heart of this dish. Red Leicester gives that authentic British tang, while sharp cheddar delivers the classic American richness. Grab mature cheddar from Waitrose or Red Leicester from Tesco Finest for the best results. Cream cheese isn't just a binder—it's what makes this sauce truly velvety. The butter should be European-style (like President's) for better flavor and lower water content. For the roux, don't rush—cook the butter and flour until it's a deep golden color but not browned, or you'll get a bitter taste. The macaroni should be elbow shape for maximum surface area to soak up the sauce.

No Red Leicester? Substitute with extra sharp cheddar—just add 1 extra tablespoon of milk to compensate for the lower moisture. Out of cream cheese? Double the cheddar and add 1 tablespoon of cornstarch to thicken the sauce. The mustard is crucial for that signature tang—don't skip it, but if you're sensitive to heat, use Dijon-style with lower heat. For the breadcrumbs, panko works too but regular breadcrumbs give a better British-style texture. The garlic can be pre-minced from a jar in a pinch, but fresh is always better if you've got it. And if you're watching calories, you can reduce the butter by 2 tablespoons and use olive oil instead—just don't tell anyone.

This mac and cheese tastes even better the next day—make extra if you can. Store leftovers in an airtight container in the fridge for up to 4 days. For freezing, let it cool completely first, then portion into containers with a layer of parchment paper between servings to prevent sticking. It keeps for 3 months in the freezer. When reheating, add a splash of milk to prevent drying out. The breadcrumb topping can be made ahead and stored separately—just toast it fresh before serving for maximum crispiness. And that golden crust? Worth the extra minute under the broiler to get it perfectly crispy.

Step-by-step instructions for American mac and cheese

Here's the method for a velvety, ultra-creamy mac and cheese with a perfect crispy breadcrumb topping.

Bring a large pot of water to a rolling boil and add 1.5 teaspoons salt—it should taste like the sea. Add the 12 oz elbow macaroni and cook until 1 minute before the package instructions for al dente. This ensures the pasta finishes cooking perfectly in the cheese sauce.

Before draining, reserve 1 cup of pasta water—this starchy liquid is essential for creating the creamiest sauce. Drain the pasta and return it to the pot, shaking gently to break up any clumps. Keep the pot over low heat to prevent the pasta from cooling while you prepare the cheese sauce.

In a separate large saucepan, melt the 0.5 cup unsalted butter over medium heat until foaming. Whisk in the 0.25 cup all-purpose flour and cook for 1-2 minutes until the mixture forms a smooth, pale roux and smells nutty. This is your sauce foundation—don't let it brown or it'll taste bitter.

Gradually whisk in the 1.5 cups whole milk over 2-3 minutes until the mixture thickens into a smooth paste. Reduce heat to low and stir in the 8 oz sharp cheddar cheese, 8 oz red leicester cheese, and 4 oz cream cheese all at once. Cook for 3-5 minutes until the cheese is completely melted and the sauce is silky smooth.

Add the cooked pasta to the cheese sauce and stir gently but thoroughly to coat every strand. The sauce should cling beautifully—if it's too thick, whisk in 2-3 tablespoons of reserved pasta water at a time until you reach your desired consistency. The mixture should be velvety but still coat the back of a spoon.

Stir in the 1 tablespoon yellow mustard, 0.5 teaspoon white pepper, 0.5 teaspoon black peppercorns, and 1.5 teaspoons salt. The mustard adds subtle tang that balances the richness, while the white pepper gives a sophisticated finish. Taste and adjust seasoning—this is where the magic happens.

In a small bowl, mix the 0.5 cup plain breadcrumbs with the 2 minced garlic cloves. Spread the macaroni and cheese evenly into a 9x9-inch baking dish (or similar size) and sprinkle the breadcrumb mixture evenly over the top. For extra crispiness, I like to press down gently with the back of a spoon.

Bake at 375°F for 15-20 minutes until the top is golden brown and bubbly. The breadcrumbs should be crispy enough to crunch between your teeth while the macaroni underneath remains creamy and warm. Watch closely in the last few minutes to prevent over-browning.

Remove from the oven and let rest for 2-3 minutes—this allows the sauce to set slightly and makes serving easier. Garnish with 2 tablespoons chopped fresh chives for a pop of color and freshness. The chives add a delicate onion flavor that complements the rich cheese perfectly.

Serve immediately while piping hot. Each forkful should deliver that perfect balance of creamy cheese sauce, tender pasta, and crispy breadcrumb topping. For extra indulgence, serve with a simple side salad or crusty bread to soak up any remaining sauce.

Perfect pairings for these flavors

Classic Side Pairings

Start with a simple arugula salad dressed with lemon vinaigrette—its peppery bite cuts through the richness of the mac and cheese beautifully. Toss 4 cups baby arugula with 2 tbsp extra-virgin olive oil, 1 tbsp fresh lemon juice, and a pinch of flaky sea salt.

For extra crunch, top with 1 tbsp toasted pine nuts or crumbled feta cheese. This keeps the meal light and fresh while balancing the heavy comfort food. 🥗

Crispy Bread Match

A garlic bread made with a baguette or sourdough loaf is a must—it's perfect for soaking up any leftover sauce.

Brush slices with melted butter, sprinkle with minced garlic, dried parsley, and grated Parmesan, then toast in the oven at 375°F for 5-7 minutes until golden and crisp. I like to serve it alongside the mac and cheese for an extra indulgent touch.

The contrast of warm, buttery bread with creamy pasta is pure comfort.

Vegetable Balance

Add a roasted vegetable medley to round out the meal. Toss 1 lb baby carrots, 1 cup Brussels sprouts, and 1 red bell pepper in 2 tbsp olive oil, 1 tsp smoked paprika, and ½ tsp salt.

Roast at 400°F for 20-25 minutes until caramelized. The natural sweetness of the vegetables complements the savory mac and cheese without overpowering it. This adds color and nutrition to your plate.

Protein Additions

For a heartier meal, add grilled chicken or smoked sausage. A simple lemon-herb grilled chicken breast (marinated in olive oil, lemon zest, rosemary, and garlic) pairs perfectly.

Alternatively, smoked gouda and apple sausage adds a smoky depth that elevates the dish. Both options turn this into a satisfying main course rather than just a side.

Dessert Pairing

End the meal with something light and refreshing, like vanilla ice cream or a fruit salad. A scoop of homemade vanilla ice cream with a drizzle of caramel sauce feels like a decadent treat after a rich mac and cheese.

For a fresher option, serve a mixed berry salad with a honey-lime dressing—the tartness cleanses the palate beautifully. 🍓

Beverage Pairings

A crisp white wine like Sauvignon Blanc or a light red such as Pinot Noir complements the dish perfectly. For beer lovers, a hoppy pale ale or a wheat beer balances the richness.

If you prefer something non-alcoholic, sparkling apple cider or iced hibiscus tea adds a refreshing contrast to the creamy, cheesy flavors. 🍷
