This Ashley Christensen-inspired mac and cheese delivers the perfect balance of crispy breadcrumb topping and velvety cheddar layers that’ll impress even the most skeptical dinner guests. The secret lies in a rich, three-cheese sauce that never breaks, paired with a golden, crunchy crust that stays crispy until the last bite.
I’ve tested countless variations to perfect this technique—no more soggy tops or grainy textures here.
The recipe begins with a classic roux base, where butter and flour cook until nutty before blending with sharp cheddar, Gruyère for depth, and a touch of cream cheese for creaminess.
The pasta cooks directly in the sauce, absorbing all that cheesy goodness, while the breadcrumb topping gets toasted to a perfect golden brown. Every element comes together in one foolproof baking dish for minimal cleanup and maximum flavor.
What you’ll end up with is a dish that looks as impressive as it tastes—crispy edges that shatter with each bite, tender pasta strands coated in a smooth, cheesy sauce, and a rich aroma that fills your kitchen.
This isn’t just comfort food; it’s a showstopper that pairs beautifully with grilled meats, roasted vegetables, or even as a standalone main course. The best part? It’s easier than it looks.
For extra indulgence, fold in cooked bacon or steamed broccoli before baking, or swap the breadcrumbs for panko for an even crunchier texture. The recipe scales perfectly for crowds, making it ideal for holidays or game day gatherings. Let’s get cooking—your taste buds will thank you.
Ingredients for ashley christensen mac and cheese
Six ingredients make this mac and cheese a showstopper with crispy crust and velvety layers.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 1 ½ lbs | Medium or jumbo size preferred |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for roux |
| All-Purpose Flour 🌾 | ½ cup | For roux base |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, block preferred |
| Gruyère Cheese 🧀 | ¾ cup | Shredded, adds depth |
| Cream Cheese 🧀 | 4 oz | Full-fat for creaminess |
| Whole Milk 🥛 | 1 ½ cups | Warmed slightly |
| Yellow Mustard 🌶️ | 1 tbsp | For tangy depth |
| Garlic Cloves 🧄 | 2 cloves | Minced for flavor |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Panko Breadcrumbs 🍞 | 1 ½ cups | For crispy topping |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For topping crispiness |
| Dried Parsley 🌿 | 1 tbsp | For garnish |
The cheeses are where the magic happens. Sharp cheddar delivers that classic tang, while Gruyère adds nutty depth—don't substitute with pre-shredded, it gets gummy. I grab block cheddar from the deli counter at Whole Foods for the best flavor, but any quality sharp cheddar works. The cream cheese is non-negotiable for that ultra-creamy texture—full-fat only. For the Gruyère, Trader Joe's has a great pre-shredded option if you're short on time. Pasta matters too—jumbo elbows hold up better than small ones when baking.
No sharp cheddar? Pepper Jack works in a pinch, but it'll add heat. Skip the Gruyère? Add extra Parmesan for umami. The mustard is key for that slight tang—Dijon works too. For a dairy-free twist, swap milk for unsweetened almond milk, but the texture won't be quite as rich. Panko is better than regular breadcrumbs—it stays crispier. If you're out, toast regular breadcrumbs with olive oil first. The garlic can be pre-minced from a jar, but fresh is always better—just smash 2 cloves with the side of your knife for quick mincing.
This mac and cheese reheats beautifully—5 minutes at 350°F covered with foil. The topping stays crispy if you bake it uncovered the last 5 minutes. Store leftovers in an airtight container for 4 days or freeze for 3 months. For parties, double the topping recipe—it's the first thing that disappears. The sauce thickens as it cools, so add a splash of milk if it seems too thick when reheating. Garnish with parsley right before serving—it keeps the topping looking fresh.
Why You'll Love This Recipe

Step-by-step instructions for Ashley Christensen's mac and cheese
Here's how to make this dreamy mac and cheese with perfect cheesy layers and that irresistible crispy breadcrumb topping.
Cook the Elbow Macaroni to Al Dente Perfection
Bring a large pot of water to a rolling boil and add the 1.5 lbs elbow macaroni. I like to use medium or jumbo size for that satisfying bite. Cook until 1 minute before the package directions specify for al dente—this ensures it finishes cooking perfectly in the oven. The pasta should have a slight bite to it when you taste test.
While it cooks, I always add 1.5 teaspoons salt to the water (about 1 tablespoon per pound of pasta). Reserve 1 cup of pasta water before draining—this starchy liquid is essential for creating a creamy sauce later. Drain the pasta and set it aside in the pot with the water still clinging to it. Don't rinse it; that surface starch helps the cheese cling beautifully.
Make the Cheesy Roux Base
In a large skillet, melt the 0.75 cup unsalted butter over medium heat. Once melted, add the 0.5 cup all-purpose flour all at once and whisk vigorously for 2-3 minutes until the mixture turns a golden brown color—this is called a roux. You're looking for a nutty aroma and that perfect golden hue.
Here's where the magic happens: slowly whisk in the 1.5 cups warm whole milk (I warm it slightly in the microwave for about 20 seconds) until smooth. The mixture will thicken into a creamy sauce. Remove from heat and stir in the 2 cups shredded sharp cheddar cheese, 0.75 cup shredded Gruyère cheese, 4 oz cream cheese, 1 tablespoon yellow mustard, 2 minced garlic cloves, 0.5 teaspoon black pepper, and the drained macaroni. Stir until the cheese is completely melted and the sauce is silky smooth.
Assemble and Bake the Cheesy Layers
Preheat your oven to 375°F. Transfer the cheesy macaroni mixture to a 9x13-inch baking dish (or similar size) and spread it evenly. The dish should be about ¾ full—this gives room for the breadcrumb topping. Sprinkle the top with 1 tablespoon dried parsley for a pop of color and fresh flavor.
Bake for 20-25 minutes until the top is bubbly and the edges are starting to set. This is where you'll get that perfect balance of creamy inside and slightly crispy edges. Don't overbake—you want it to be just set, not dry. If you're unsure, check at the 20-minute mark and adjust based on your oven's tendencies.
Create the Crispy Breadcrumb Topping
While the mac and cheese bakes, mix the 1.5 cups panko breadcrumbs with the 2 tablespoons extra-virgin olive oil in a small bowl. Spread this mixture evenly over the top of the baked mac and cheese. Return it to the oven and bake for an additional 8-10 minutes until the breadcrumbs are golden brown and crispy.
Here's the thing—I like to broil the mac and cheese for the last 2-3 minutes of this final baking time. Keep a close eye on it to prevent burning. The broiler gives you that extra crispiness and a beautiful golden color that makes this dish look (and taste) restaurant-quality. Let it cool for 5-10 minutes before serving to allow the breadcrumbs to set completely.
Serve and Enjoy the Ultimate Comfort Food
Slice into perfect squares and serve immediately. Each bite should deliver that creamy, cheesy goodness with a satisfying crunch from the breadcrumb topping. The sharp cheddar and Gruyère combination gives a rich, complex flavor, while the mustard adds just enough tang to balance it all out.
I promise, this mac and cheese is worth every calorie. The crispy breadcrumb topping takes it to the next level, making it feel like a special occasion dish. Pair it with a simple green salad and you've got a complete meal that's sure to impress your family and friends. Enjoy!
Pro Tips For Making Ashley Christensen Mac And Cheese
- Cook Pasta Al Dente, Then Toss: The recipe calls for elbow macaroni, and I learned this the hard way—overcooked pasta turns mushy when mixed with the cheese sauce. Boil it just until it’s al dente (about 1 minute less than package instructions), drain, and immediately shock it in ice water for 30 seconds. This stops the cooking and keeps the texture perfect when you fold in the roux.
- Grate Cheese Fresh: Pre-shredded cheese is coated in anti-caking agents that make the sauce grainy. Skip the bagged stuff and grate sharp cheddar and Gruyère yourself—use a box grater for even, fine shreds. Store-bought cheese won’t melt as smoothly, and you’ll notice the difference in every bite.
- Low and Slow for Roux: Whisking butter and flour over high heat can burn before the sauce thickens. Start on medium-low, stir like your life depends on it, and let it cook for 2–3 minutes until it smells nutty but not toasted. This builds flavor without bitterness, and the sauce will coat the pasta perfectly.
- Add Cheese in Stages: Dumping all the cheese at once can make the sauce seize up. Start with half the cheddar and Gruyère, stir until melted, then add the rest a handful at a time. If it looks too thick, splash in a tablespoon of warm milk (or pasta water) to loosen it—this keeps the texture creamy, not gloppy.
Make-ahead tips for ashley christensen mac and cheese
Prep Ahead for Crowds
Make the cheesy sauce up to 24 hours ahead and store it in an airtight container in the fridge. The flavors deepen overnight, and you'll save time on baking day.
Just reheat gently on the stovetop with a splash of milk to restore creaminess before mixing with pasta. This is my go-to strategy for holiday gatherings—less stress, more flavor. 💫
Freezer-Friendly Assembly
Assemble the mac and cheese in the baking dish, but skip the breadcrumb topping. Cover tightly with foil and freeze for up to 3 months. When ready to serve, thaw in the fridge overnight, then bake uncovered at 375°F for 25-30 minutes.
Add fresh breadcrumbs and broil for 2-3 minutes before serving to restore that crispy texture. Perfect for busy weeknights!
Make-Ahead Topping Hack
Mix the breadcrumb topping ingredients ahead and store in a sealed container for up to 5 days. When ready to bake, simply spread it on top—no last-minute prep needed.
For extra crispiness, toast the breadcrumbs in a dry skillet for 2-3 minutes before adding olive oil, then store in the fridge. This shortcut keeps your topping game strong without sacrificing flavor. ✨
Portion Control for Parties
Divide the assembled mac and cheese into individual 8x8-inch baking dishes before baking. This ensures each serving gets perfectly crispy edges and creamy centers. Bake smaller portions at 375°F for 20-25 minutes, then top with breadcrumbs and broil for 2 minutes.
Guests will love the restaurant-style presentation, and you'll avoid the "who gets the last piece?" dilemma. 🍽️
Reheating Leftovers
For best results, reheat leftovers covered with foil at 350°F for 10-15 minutes. Uncover and broil for 2-3 minutes to restore crispiness. If the sauce seems too thick, add 1-2 tablespoons of milk or pasta water while reheating.
Store leftovers in airtight containers for up to 4 days, or freeze for 3 months for future meals.
Game Day Prep
Double the recipe and bake in two 9x13-inch dishes for easy serving at football games or tailgates. Keep one dish covered with foil in a slow cooker on warm** while serving the other.
The slow cooker maintains temperature perfectly, so you can focus on the party without worrying about reheating. Add extra breadcrumbs to the top before serving for maximum crunch. 🏈

Frequently asked questions
Can I make this mac and cheese without baking it?
For a stovetop version, cook the pasta as directed, then make the cheesy sauce and mix it with the drained pasta. Heat everything together over low heat for 5-7 minutes, stirring constantly until creamy. The texture will be slightly softer than baked, but still rich and delicious. For extra richness, stir in 1 tablespoon butter at the end.
What's the best cheese substitute if I don't have Gruyère?
Gruyère adds nutty depth, but you can substitute with Parmesan or Swiss cheese for a similar flavor profile. For a dairy-free option, use nutritional yeast (about 1/4 cup) mixed with extra sharp cheddar to mimic the umami. Just reduce the total cheese by 1/4 cup to maintain balance. The mustard and cream cheese will still give that tangy creaminess.
Why did my breadcrumb topping get soggy?
Soggy toppings usually happen from one of two issues: baking too long at high heat or not toasting the breadcrumbs enough first. To fix it, try this: mix 1 extra tablespoon of flour into the breadcrumb topping, then bake at 350°F for the final 5 minutes instead of broiling. Also, toast your breadcrumbs in a dry skillet for 2-3 minutes before mixing with oil. This creates a barrier that locks in crispiness.
Can I use this recipe for a vegan mac and cheese?
With some adjustments, yes! Swap butter for vegan butter or olive oil, use unsweetened almond milk instead of whole milk, and replace cheeses with vegan cheddar shreds (like Violife or Daiya) plus 1/4 cup nutritional yeast for depth. For the topping, use panko mixed with olive oil or crushed vegan crackers. The texture won't be identical, but it'll still be creamy and satisfying.
How do I keep the pasta from getting mushy when baking?
Undercooking the pasta slightly before baking is key—cook it just 1 minute less than package instructions say. Also, make sure your baking dish isn't too large (use 9x13-inch or similar) so the pasta isn't spread too thin. Finally, bake at 375°F rather than higher heat, and cover with foil for the first 20 minutes to trap moisture. The pasta should finish cooking perfectly in the oven.
