Ingredients for baked panera mac and cheese

Here's what you need to recreate that iconic crispy-topped, stretchy-cheese mac and cheese.

The cheeses are non-negotiable—sharp white cheddar for tang and Gruyère for that signature melt. Grab a wedge of each from the deli counter (pre-shredded gets clumpy). For the breadcrumbs, Panko is your best friend—it stays crispy and adds texture. I always buy mine in bulk from Costco or Trader Joe's since it's a staple. The elbow macaroni should be the medium-sized variety—it holds up better during baking than the small stuff. Look for the Barilla brand if you're in the U.S., or any reputable store-brand pasta.

No sharp cheddar? Extra-sharp cheddar at half the amount works in a pinch. Gruyère hard to find? Comté cheese is a decent swap, though it's pricier. For the roux, don't skip the butter—it's what makes the sauce velvety. If you're out of milk, half-and-half gives you extra richness. The mustard powder adds that subtle tang you taste in the restaurant version—don't leave it out! For the breadcrumb topping, you can use regular breadcrumbs, but Panko mixed with a little Parmesan gives you that perfect crunch.

Cook the pasta just shy of al dente—it'll finish cooking in the oven. The cheese sauce keeps for 3 days in the fridge if you make it ahead, but the breadcrumb topping is best added fresh before baking. For leftovers, store the whole casserole (covered) in the fridge—reheat at 350°F until bubbly. Freezes beautifully for up to 3 months if you wrap it tightly. Pro tip: Make a double batch—this disappears fast, especially with that crispy top calling your name.

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

Get that perfect Panera-style mac and cheese with a golden, crunchy breadcrumb crown and gooey cheese rivers.

Bring a large pot of water to a rolling boil and add 1.5 lbs elbow macaroni. I like to use about 12 cups of water for this quantity—it should taste like the ocean when you dip in a noodle. Cook until 1 minute before the package directions say al dente, then drain immediately and return to the pot.

Here's the thing—you want those noodles to finish cooking in the oven while soaking up all that cheesy goodness. If you overcook them now, they'll turn mushy later. Toss the drained macaroni with 1 tablespoon olive oil to prevent sticking, and set aside while you make the sauce.

In a large saucepan over medium heat, melt the 0.5 cup unsalted butter until it foams. Whisk in the 0.25 cup all-purpose flour and cook for 1-2 minutes until it forms a smooth, golden roux. This is your flavor foundation—don't rush it or you'll get a raw flour taste.

Slowly whisk in the 1.5 cups whole milk to prevent lumps from forming. Keep stirring until the mixture thickens enough to coat the back of a spoon. Then reduce heat to low and stir in the 1.5 cups sharp white cheddar and 1 cup gruyère, along with the 0.5 tsp dried mustard powder, 1.5 tsp salt, 0.5 tsp black pepper, and 0.5 tsp garlic powder. Stir until completely melted and smooth—this should take about 3-4 minutes.

Add the cooked macaroni to the cheese sauce and stir gently until everything is evenly coated. You want those noodles swimming in that creamy, melty goodness. If the sauce looks too thick, add 2-3 tablespoons of the pasta water you reserved earlier—just enough to loosen it slightly while keeping it rich.

Taste and adjust seasoning if needed. I usually add a pinch more salt at this point because cheddar can vary in saltiness. The sauce should be thick enough to coat the back of a spoon but still silky smooth. Transfer the macaroni mixture to a greased 9x13-inch baking dish and spread it out evenly.

In a small bowl, mix together the 1 cup panko breadcrumbs and 0.5 cup parmesan cheese. The panko gives that perfect crispy texture while the parmesan adds depth of flavor. Sprinkle this mixture evenly over the top of the macaroni, pressing down gently to help it stick.

Here's where the magic happens: pop the baking dish in the refrigerator for 15 minutes to let the breadcrumbs firm up slightly. This chilling step is crucial—it prevents the crown from sliding off during baking and ensures that crispy texture we're after.

Preheat your oven to 375°F. Bake the mac and cheese for 25-30 minutes until the top is deep golden brown and the edges are bubbling. You'll see those beautiful cheese rivers forming—this is when you know it's ready. If the top isn't brown enough after 25 minutes, broil for 1-2 minutes at the end, watching closely to avoid burning.

Let it rest for 5 minutes before serving—this gives the breadcrumb crown time to set properly and prevents a runny cheese disaster. The mac should be creamy inside with that perfect crispy crust on top, and each bite should deliver that stretchy, cheesy goodness we all love.

Pro cooking tips for perfect results

Cheese Sauce Secrets

The roux is where the magic happens—cook it until it’s a golden brown color, not white. This adds depth to your sauce. I use unsalted butter because it gives you control over the seasoning. If you rush the roux, you’ll taste raw flour, and that’s a flavor killer. 🧈

For the cheeses, sharp white cheddar gives that tangy kick, while Gruyère adds that signature melt. If your cheddar isn’t sharp enough, add an extra ¼ tsp of mustard powder to boost the tang. Always shred your own cheese—pre-shredded clumps up and ruins the texture.

Pasta Perfection

Cook your pasta 1 minute less than the package suggests—it’ll finish cooking in the oven. Tossing it with 1 tablespoon olive oil right after draining prevents sticking and helps it absorb the cheese sauce better. I like to use Barilla elbow macaroni because it holds up well during baking.

Don’t overmix the macaroni and cheese sauce after combining—just stir until the noodles are coated. Overworking it makes the sauce gummy. If it’s too thick, add 2 tablespoons of pasta water to loosen it slightly while keeping that rich, creamy texture.

Crispy Top Tricks

Chilling the dish for 15 minutes before baking is non-negotiable—it sets the breadcrumb crown so it doesn’t slide off. Use Panko breadcrumbs mixed with Parmesan for that perfect crunch. Press them down gently to help them adhere to the cheese.

For an extra-crispy top, broil for 1-2 minutes at the end if needed, but watch it like a hawk—it burns fast. The breadcrumb crown should be golden brown, not black.

Let it rest for 5 minutes before serving so the cheese sets up properly and you don’t end up with a runny mess.

Oven Temperature Matters

Bake at 375°F—any hotter and the top burns before the center is done. If your oven runs hot, reduce the temperature to 350°F and bake for 35-40 minutes. The cheese rivers should form naturally as it bakes—this is your sign it’s ready.

For even baking, place your dish on the middle rack of the oven. If you’re using a glass baking dish, it might need 5-10 extra minutes to brown compared to metal.

Always grease your dish well with olive oil to prevent sticking—trust me, you don’t want to scrub cheese off later. 🔥
