Ingredients for american mac and cheese recipe uk

Sharp cheddars, rich roux, and crispy panko—here’s what makes this UK mac and cheese irresistible.

The cheeses are non-negotiable. Red Leicester gives that signature British tang while sharp English cheddar delivers the melt you crave. Grab them pre-grated from Waitrose or M&S for convenience, but grating your own from a block makes all the difference. For the butter, Plugrá or Clover brands are ideal—they handle high heat beautifully. If you're short on time, swap the roux flour for cornstarch (use half the amount) for an instant thickener, though purists won't approve.

No heavy cream? Full-fat Greek yogurt thinned with milk works in a pinch, though texture will differ slightly. Short on Red Leicester? Double the sharp cheddar—just add a splash of apple cider vinegar (1 tsp) to mimic the tang. For the panko, Japanese-style (like Shiniku) gives the best crunch, but any breadcrumbs will do. The smoked paprika is optional but adds that smoky depth you find in American versions—Penzeys has a great UK-sourced option. Pro tip: Toast your panko with a pinch of butter before topping for extra crispiness.

This bakes best when assembled just before baking—30 minutes in the oven at 375°F (190°C) gives that perfect golden crust. Leftovers? Reheat covered with a splash of milk to restore creaminess. Keeps 4 days in the fridge or 3 months frozen—portion into single servings before freezing for easy reheats. The sauce thickens as it cools, so add a splash of milk if it seems too stiff when reheating.

Step-by-step instructions for baked mac and cheese with crispy topping

Here's how to make the ultimate American-style baked mac and cheese with that signature golden crust and melty cheddar streaks.

Bring a large pot of salted water to a rolling boil—it should taste like seawater. Add the 12 oz elbow macaroni and cook for 1 minute less than the package instructions. You want it al dente, with a slight bite. Drain immediately and give it a good shake in the colander to remove excess water. I like to return it to the pot and toss with a bit of cooking oil to prevent sticking.

Don't rinse the pasta—those surface starches are what help the cheese cling beautifully. While the pasta cooks, I like to prep everything else so nothing gets forgotten. This is where good mise en place really pays off.

In a large saucepan, melt the 0.5 cup unsalted butter over medium heat until it foams. Whisk in the 0.5 cup all-purpose flour and cook for 1-2 minutes until it forms a smooth, pale roux—this is your sauce foundation. Here's the thing: don't let it brown or you'll get a floury taste instead of that rich, velvety texture we're after.

Slowly whisk in the 2 cups whole milk and 0.5 cup heavy cream, letting each addition cook for 30 seconds before adding more. Once fully incorporated, reduce heat to low and stir in the 2 cups sharp English cheddar cheese and 1 cup red Leicester cheese until completely melted and smooth. The sauce should be thick enough to coat the back of a spoon but still flow easily.

Add the drained pasta to the cheese sauce and stir vigorously for 2-3 minutes until every noodle is fully coated. This is where the magic happens—you'll see those beautiful cheddar streaks forming as the cheese melts into the sauce. Stir in the 1 tbsp yellow mustard, 1.5 tsp kosher salt, 0.5 tsp ground black pepper, 0.5 tsp garlic powder, and 0.25 tsp smoked paprika. Taste and adjust seasoning if needed—this is your chance to balance the flavors before baking.

Transfer the mac and cheese to a 9x9-inch baking dish and spread it evenly. The goal is a smooth, level surface that will bake uniformly. I use a rubber spatula to scrape every last bit from the pot—no one likes dry mac and cheese in the corners!

In a small bowl, mix together the 0.5 cup panko breadcrumbs, any remaining 0.25 tsp smoked paprika, and a pinch of 0.25 tsp kosher salt. Sprinkle this evenly over the top of the mac and cheese, pressing down gently with your fingers to help it adhere. This topping is what gives that irresistible crunch we all love—don't skip it!

Bake at 375°F for 20-25 minutes until the top is deep golden brown and the edges are bubbling. The cheese should be melted all the way through with those beautiful streaks visible. If the top isn't brown enough after 20 minutes, broil for 1-2 minutes at the end—just watch it closely so it doesn't burn.

Let the mac and cheese rest for 5-10 minutes before serving. This resting period allows the cheese to set slightly, making it easier to slice and preventing that sad, soupy slide. The texture should be creamy yet firm enough to hold its shape when served.

Serve immediately with a side of buttery green beans or a crisp salad. The contrast of the warm, cheesy mac and cheese with something cool and fresh makes every bite even better. Leftovers? Reheat in the oven at 350°F until warmed through—microwaving makes the topping soggy, and we simply can't allow that.

Best sauces and condiments for american mac and cheese recipe uk

Classic Cheese Sauce

This is the foundation of any great mac and cheese, and the roux-based method is non-negotiable for that velvety texture. I start with 0.5 cup unsalted butter and 0.5 cup all-purpose flour cooked to a pale roux—never let it brown!

Then I whisk in 2 cups whole milk and 0.5 cup heavy cream gradually to avoid lumps. The key is patience: let each addition cook for 30 seconds before adding more. Stir in 2 cups sharp English cheddar and 1 cup Red Leicester until completely melted.

For extra depth, add 1 tbsp yellow mustard—it brightens the sauce without overpowering. 🧈

Spicy Kick

If you love heat, fold in ½ tsp cayenne pepper or 1 tsp hot paprika when combining the pasta and sauce. For a smoky twist, add ½ tsp smoked paprika—it mimics the depth of American-style mac without needing specialty ingredients.

I like to toast the spices in a dry pan for 30 seconds before adding to enhance their flavor. Trust me, this makes all the difference in a simple dish like this. 🌶️

Creamy Mustard Sauce

Swap the classic cheese sauce for a Dijon mustard base by whisking 3 tbsp Dijon mustard into the roux before adding milk. This version has a tangy, almost French bistro vibe. I balance it with 1 tbsp honey to soften the heat, then proceed with the same cheese additions.

It’s lighter but still rich—perfect if you’re watching fat content. The mustard also helps the sauce cling to the pasta better. 🍯

Bacon-Infused Sauce

For a smoky, savory depth, cook 4 oz chopped bacon until crispy, then drain all but 2 tbsp of the fat. Use this bacon fat to make your roux instead of butter—it adds incredible flavor. Stir the crumbled bacon into the finished sauce before baking.

The fat renders into the cheese, creating pockets of smoky richness. If you’re short on time, use ½ cup cooked bacon bits stirred in at the end. 🥓

Herb-Infused Cream

Brighten the sauce with 1 tsp dried thyme or 1 tbsp fresh chives, stirred in with the cheese. For a pop of color and freshness, fold in 2 tbsp crème fraîche at the end—it adds a tangy creaminess that cuts through the richness.

I also like adding ½ tsp onion powder to the roux for subtle sweetness. This version feels lighter but still indulgent. 🌿

Topping Variations

Beyond panko, try crushed potato chips (like Walkers Ready Salted) for a salty crunch, or grated Parmesan mixed with breadcrumbs for a cheesy crust. For extra richness, top with buttered breadcrumbs and a sprinkle of paprika before baking.

If you’re feeling fancy, add a layer of crispy fried shallots or crumbled feta for a Mediterranean twist. 🍟
