Ingredients for baked macaroni and cheese recipe with dry mustard

Six ingredients make this mac and cheese extraordinary—especially that mustard powder.

The cheese is where magic happens. Sharp cheddar gives the classic tang, but white cheddar adds that nutty depth the intro promised. I grab Kraft 2% Milk Sharp Cheddar from the store—it shreds perfectly and melts smooth. For the white cheddar, Cabot or Tillamook are my go-tos, but any aged cheddar works. The mustard powder? Mustard powder, not mustard—this is key. Penzeys sells a great one, but the stuff in the spice aisle at Walmart is fine too. Pro tip: toast your breadcrumbs in a dry pan for 2 minutes before mixing with butter—extra crispy every time.

No sharp cheddar? Extra-sharp white cheddar plus a pinch of smoked paprika mimics that depth. Heavy cream too expensive? Half-and-half works, but the sauce won't be quite as rich. The mustard powder non-negotiable—it's what makes this stand out. No panko? Regular breadcrumbs toasted do the job, but they won't be as crispy. The garlic powder is optional but worth it for that subtle aroma. For the roux, don't rush it—cook the butter and flour until it's light golden, not brown. That's what makes the sauce silky.

This reheats like a dream—just cover with foil and pop in the oven at 350°F for 10-15 minutes. The topping stays crispy if you bake it uncovered the last 5 minutes. Keeps 4 days in the fridge, but honestly? It disappears faster. Freezes beautifully for 3 months—portion into single servings before freezing. I always make a double batch because this disappears faster than you can say 'crispy topping'. Leftovers? Toss with a fried egg on top—breakfast for dinner, anyone?

Step-by-step instructions for baked macaroni and cheese with dry mustard

Here's how to make the ultimate baked mac and cheese—creamy, tangy, and topped with golden, crispy perfection.

Bring a large pot of water to a rolling boil and add 12 oz elbow macaroni. Cook until 1 minute before the package directions for al dente—you want it slightly firm to hold up in the oven. Drain and set aside, reserving 1 cup of pasta water for the sauce. This starchy water is your secret weapon for a silky, velvety texture.

Don't rinse the pasta—those surface starches help the cheese cling perfectly. I like to give the drained pasta a quick shake in the colander to break up any clumps before moving to the next step. This ensures even coating with the cheese sauce later.

In a large skillet, melt 4 tbsp unsalted butter over medium heat. Once melted, whisk in 2 tbsp all-purpose flour and cook for 1-2 minutes until the mixture turns a light golden color—this is your roux. Here's where the magic happens: slowly whisk in the 0.5 cup heavy whipping cream and 0.5 cup whole milk until smooth.

Reduce heat to low and gradually add the 2 cups sharp cheddar cheese and 1 cup extra-sharp white cheddar cheese, stirring constantly until fully melted. Sprinkle in the 0.5 tsp dry mustard powder and 0.25 tsp garlic powder, mixing well. The mustard powder is what gives this recipe that signature tangy depth—don't skip it! Taste and adjust seasoning with 1.5 tsp kosher salt and 0.5 tsp black pepper. If the sauce seems too thick, add a splash of the reserved pasta water to reach your desired consistency.

Add the cooked elbow macaroni to the skillet with the cheese sauce and stir gently until every strand is fully coated. The sauce should look glossy and cling to the pasta. Transfer the entire mixture to a 9x13-inch baking dish and spread it out evenly. This step is crucial for even baking—don't skip spreading it out!

I like to use a spatula to smooth the top, making sure there are no dry spots. The cheese sauce should be thick enough to hold its shape but still have a slight sheen. If it looks too thin, add a bit more of that reserved pasta water to help it set properly in the oven.

In a small bowl, mix together the 0.5 cup panko breadcrumbs, 1 tbsp extra-virgin olive oil, and an extra pinch of kosher salt. Sprinkle this mixture evenly over the top of the mac and cheese, pressing down gently with the back of a spoon to help it adhere. The olive oil is key here—it helps create that golden, crispy crust we're after.

Dot the top with the remaining 4 tbsp unsalted butter, cutting it into small pieces. This butter will melt and create pockets of extra richness as it bakes. Pop the dish in the refrigerator for 15 minutes to chill slightly—this helps the topping stay crispy instead of sinking into the sauce.

Preheat your oven to 375°F. Bake the mac and cheese for 20-25 minutes until the top is deep golden brown and the edges are bubbling. The crispy topping is what makes this dish special, so keep an eye on it—if it starts to brown too quickly, tent it with foil to prevent burning.

When it's done, let it rest for 5-10 minutes before serving. This resting time allows the cheese to set slightly, making it easier to slice and preventing a runny mess. The result should be a creamy, tangy mac and cheese with a golden, crispy top that's impossible to resist—every bite delivers that perfect combination of textures!

It’s a perfect balance of comfort and innovation. 🌿
