Ingredients for ashley christensen mac and cheese
Sixteen ingredients transform into Ashley Christensen's legendary crispy-crowned, velvety mac and cheese masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 1 ½ lb | Medium or jumbo size preferred |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for roux formation |
| All-Purpose Flour 🌾 | ½ cup | Sifted, for smooth roux |
| Whole Milk 🥛 | 3 cups | Room temperature preferred |
| Sharp White Cheddar Cheese 🧀 | 1 ½ cups | Shredded, aged 6+ months |
| Monterey Jack Cheese 🧀 | 1 cup | Shredded, mild flavor |
| Gruyère Cheese 🧀 | ½ cup | Freshly grated, nutty depth |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For seasoning, not roux |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Cracked peppercorns preferred |
| Nutritional Yeast 🍃 | 2 tbsp | For umami depth, optional |
| Panko Breadcrumbs 🍞 | 1 ½ cups | Japanese-style for extra crisp |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | Light drizzle for topping |
| Garlic Powder 🧄 | ½ tsp | For breadcrumb seasoning |
| Dried Parsley Flakes 🌿 | 1 tsp | For garnish, optional |
The cheese selection is non-negotiable for this recipe. Sharp white cheddar provides the signature tang, while Gruyère adds luxurious depth—skip the pre-shredded kind (it's coated with anti-caking agents that prevent proper melting). For the best quality, Whole Foods Market or specialty cheese shops carry aged cheddar and fresh Gruyère. If you're using block cheese, grate it yourself for maximum moisture retention. The Monterey Jack balances the sharpness, so don't substitute with mild cheddar. For the breadcrumbs, Panko is essential—its light, airy texture creates that signature crispy crown. Trader Joe's sells it in bulk at unbeatable prices.
No sharp cheddar? Extra-sharp cheddar at half the quantity works in a pinch, though the flavor won't be identical. Substituting Gruyère? Comté or Emmental both work well, but increase to 0.75 cup for comparable richness. The nutritional yeast is optional but adds that restaurant-quality umami—Bob's Red Mill brand is widely available. For the roux, European-style butter (like Plugrá) has higher fat content, which creates a silkier sauce. The garlic powder in the breadcrumbs can be swapped for fresh minced garlic at double the amount, but toast it first for deeper flavor. If you're making this ahead, assemble everything except the breadcrumb topping and refrigerate overnight—the flavors meld beautifully.
This mac and cheese reheats beautifully—cover with foil and bake at 350°F for 15-20 minutes until the crown is crispy again. For best results, reheat only what you'll serve immediately to maintain that perfect texture. The breadcrumb topping loses crispiness when reheated multiple times, so consider making a fresh batch for leftovers. Store the assembled (unbaked) casserole in the fridge for up to 2 days or freeze the baked version for 3 months. When freezing, wrap tightly in aluminum foil before plastic to prevent freezer burn. The cheese sauce can be made ahead and stored in the fridge for 3 days—just reheat gently before assembling.

Step-by-step instructions for Ashley Christensen's mac and cheese
Master this technique and you'll achieve Ashley's signature crispy breadcrumb crown over velvety cheese.
🍳 Step 1: Create the Perfect Roux Foundation
In a heavy-bottomed saucepan, melt the 0.75 cup unsalted butter over medium-low heat. I use cold, cubed butter to ensure gradual melting and even distribution. Once fully melted, reduce heat to low and gradually whisk in the 0.5 cup all-purpose flour—this is your roux.
Cook the roux for 3-4 minutes, stirring constantly with a wooden spoon, until it turns a rich, golden pale blond color. This color indicates proper development without burning. The roux should coat the back of a spoon and smell nutty—this is the flavor base for your entire dish. If it darkens too quickly, reduce the heat immediately to prevent bitterness.
🥘 Step 2: Develop the Ultra-Smooth Cheese Sauce
Slowly pour in the 3 cups whole milk while whisking vigorously to prevent lumps. Increase heat to medium-low and continue whisking for 5-7 minutes until the mixture thickens and coats the back of a spoon. This process should take patience—rushing leads to a grainy sauce.
Reduce heat to low and stir in the 1.5 cups sharp white cheddar cheese, 1 cup monterey jack cheese, 0.5 cup gruyère cheese, 2 tbsp nutritional yeast, 1.5 tsp diamond crystal kosher salt, and 0.5 tsp freshly ground black pepper. Stir until completely melted and smooth. The sauce should be silky with no visible cheese particles. If it's too thick, whisk in 1-2 tablespoons of milk to reach a pourable consistency.
🍳 Step 3: Cook the Pasta to Al Dente Perfection
While the sauce simmers, cook the 1.5 lb elbow macaroni in a large pot of salted boiling water (it should taste like the sea) until 1 minute before al dente. Drain immediately and return to the pot. Add ½ cup of the cheese sauce and toss vigorously to coat the pasta completely. This step prevents the pasta from absorbing too much liquid later.
Transfer the pasta to a greased 9x13-inch baking dish, spreading it evenly. Pour the remaining cheese sauce over the pasta, pressing down gently to ensure even distribution. The mixture should look glossy and well-coated. Sprinkle the 1.5 cups panko breadcrumbs evenly over the top, pressing down lightly to adhere.
🔥 Step 4: Bake to Golden Crispy Perfection
Preheat your oven to 375°F. Drizzle the 2 tbsp extra-virgin olive oil evenly over the breadcrumbs, then sprinkle with 0.5 tsp garlic powder and 1 tsp dried parsley flakes. Bake for 20-25 minutes until the breadcrumb topping is deep golden brown and crispy, and the edges are bubbling.
For the ultimate finish, broil for 1-2 minutes on high, watching closely to prevent burning. The cheese should be fully melted with a smooth, glossy surface, and the breadcrumb crown should be crisp enough to stand up to a fork. Let rest for 5 minutes before serving—this allows the cheese to set slightly for cleaner slices.
Pro Tips For Making Ashley Christensen Mac And Cheese
- Salt the Milk First: Toss a generous pinch of salt—about ½ teaspoon—into the warm milk before making the roux. I used to skip this, and the cheese always tasted flat; salted milk carries flavor through the sauce like a silent partner.
- Shred Cheese Small: Cut the sharp white cheddar into ¼-inch cubes, then pulse them twice in a food processor for a powdery texture. Big chunks melt unevenly, and you’ll end up with a lumpy mess—trust me, I’ve picked them out of my teeth.
- Low and Slow for Roux: Whisk the butter and flour over medium-low heat for 3–4 minutes until it’s a pale golden color, not brown. Rush it, and you’ll taste flour; let it cook too long, and the sauce turns bitter. Patience here makes all the difference.
- Reserve Starchy Water: Save ½ cup of the pasta water before draining, then add it to the cheese sauce in small splashes until creamy. The starch acts like a glue—no extra milk needed, and the sauce won’t break. I learned this after three attempts with gluey, watery results.
Storing and reheating your ashley christensen mac and cheese
Refrigerator Storage
Store your assembled (unbaked) mac and cheese in an airtight container for up to 2 days. The flavors actually deepen overnight—just cover tightly with plastic wrap and refrigerate. When ready to bake, preheat to 375°F and bake for 25-30 minutes until the breadcrumb crown is crispy again. 💛
Freezer Prep Tips
For long-term storage, bake the dish first, then cool completely before wrapping tightly in aluminum foil followed by plastic wrap. Freeze for up to 3 months.
Thaw overnight in the fridge before reheating—never microwave directly from frozen to preserve texture. Reheat covered with foil at 350°F for 20-25 minutes.
Reheating Perfection
For stovetop reheating, transfer portions to a skillet with 2 tbsp milk or broth to prevent drying. Warm over low heat for 5-7 minutes, stirring constantly, until bubbly. The breadcrumb crown will soften slightly but regain crispiness when broiled for 1-2 minutes afterward.
For microwave reheating, cover with a damp paper towel and heat in 30-second bursts at 50% power, stirring between each. 🔥
Make-Ahead Sauce
Make the cheese sauce 3 days ahead and store in an airtight container in the fridge. Reheat gently on the stovetop before assembling with pasta. This shortcut saves time while ensuring the sauce remains silky smooth.
I always prep the sauce first when making this recipe—it’s the foundation of everything. ✨
Breadcrumb Crown Revival
The breadcrumb topping loses crispiness with reheating, so I recommend making a fresh batch for leftovers. For a quick fix, sprinkle extra panko on top after reheating and broil for 1-2 minutes to restore crunch.
Keep a small bag of breadcrumbs on hand specifically for this purpose—it makes all the difference. 🍞

Frequently asked questions
Why does this recipe use three different cheeses?
Each cheese brings something special: the sharp white cheddar delivers tangy flavor, Monterey Jack adds creaminess, and Gruyère contributes nutty depth. This trio creates a complex, restaurant-quality taste that's far more interesting than single-cheese versions. The blend also melts more smoothly than individual cheeses alone.
Can I make this dish ahead of time?
Assemble the dish (without baking) up to 2 days ahead and refrigerate. For the best results, bake it straight from the fridge—just add 5 extra minutes to the baking time. You can also make the cheese sauce 3 days ahead and store it separately. The breadcrumb topping should always be added fresh before baking for maximum crispiness.
What if my breadcrumb topping isn't crispy?
Check your oven temperature—it needs to be 375°F and properly calibrated. For extra crispiness, broil for 1-2 minutes at the end, watching closely to prevent burning. Also ensure you're using Panko breadcrumbs (not regular) and pressing them down lightly before baking. If it's still soft, bake for 5 more minutes until golden brown.
Can I substitute the elbow macaroni?
Yes, but choose a medium or jumbo size for better texture. Penne or fusilli work well too, but avoid small shapes like orzo—they absorb too much sauce. For a gluten-free option, use gluten-free elbow macaroni and ensure all other ingredients are certified gluten-free. The cooking time may vary slightly, so check for al dente doneness.
How do I make this vegetarian?
This recipe is already vegetarian-friendly! Simply omit any optional meat add-ins like bacon. For extra richness, stir in 2 tbsp nutritional yeast or 1 tbsp white miso paste when making the cheese sauce. The existing ingredients provide plenty of depth without animal products. The crispy breadcrumb topping remains perfectly vegetarian as well.
