Why did my cheese sauce turn out grainy?

A grainy sauce usually results from overheating the cheese or adding it to a too-hot base. Always remove the sauce from heat before adding cheese and stir gently until just melted. Using pre-shredded cheese with anti-caking agents can also cause graininess.

Can I use different pasta shapes?

Absolutely! While elbow macaroni is traditional, any short pasta with nooks and crannies to hold sauce works wonderfully. Try cavatappi, shells, or rotini for a fun twist. Adjust cooking times as needed to reach al dente.

How do I make this mac and cheese even creamier?

For ultra-creaminess, increase the ratio of sauce to pasta. You can also add 2-3 ounces of cream cheese to the sauce, or replace some of the milk with heavy cream. Just remember that more liquid means you may need to extend the baking time slightly.

My topping isn't getting crispy enough. What am I doing wrong?

If your breadcrumb topping remains pale, try placing the dish under the broiler for 1-2 minutes at the end of baking—but watch carefully! Another option is to pre-toast the buttered breadcrumbs in a skillet until golden before adding them to the top of the dish.

How to Make Baked Mac and Cheese

Step 1: Prepare the Pasta

Cook the elbow macaroni in generously salted water until al dente according to package directions. Remember, the pasta will continue cooking in the oven, so keep it slightly firm. Drain and rinse under cold water to stop the cooking process.

Step 2: Create the Cheese Sauce Base

While the pasta cooks, melt butter in a large oven-safe skillet over medium heat. Add the minced onion with a pinch of salt and cook until translucent and soft. Add the garlic and cook until fragrant, just 30 seconds more.

Step 3: Make the Roux

Sprinkle the flour over the butter mixture and stir continuously until it forms a paste. Cook for about 1-2 minutes to remove the raw flour taste. This is your roux—the thickening base for your cheese sauce.

Step 4: Develop the Sauce

Gradually pour in the milk while whisking constantly to prevent lumps. Continue whisking until the mixture thickens enough to coat the back of a spoon. This takes patience—about 5-7 minutes of gentle cooking and whisking.

Step 5: Add Creaminess and Cheese

Whisk in the sour cream until smooth, then remove from heat. Mix your shredded cheeses together and set aside 2 cups for the topping. Add the remaining cheese to the sauce, stirring until completely melted and velvety smooth.

Step 6: Combine and Transfer

Fold the cooked macaroni into the cheese sauce, ensuring every piece is generously coated. Transfer the mixture to a 9×13-inch baking dish if you weren’t using an oven-safe skillet.

Step 7: Prepare the Topping

Melt the remaining butter in a small pan, add the Panko breadcrumbs, salt, and garlic powder. Stir until the crumbs are evenly coated and golden. Top the macaroni with the reserved cheese and the seasoned breadcrumbs.

Step 8: Bake to Perfection

Bake in the preheated 375°F oven for 15 minutes until bubbly around the edges with a beautifully golden topping. Let it rest for 5 minutes before serving to allow the sauce to set slightly.

Pro Tips for Making the Recipe

Grate Your Own Cheese: Pre-shredded cheese contains anti-caking agents that prevent proper melting. Taking a few minutes to grate fresh cheese makes a world of difference.
Room Temperature Ingredients: Bring milk and sour cream to room temperature before adding them to prevent the sauce from breaking or becoming grainy.
Don’t Overcook the Pasta: Keep it firm as it will soften more during baking. No one wants mushy mac and cheese!
Layer Your Cheese: Reserve some cheese for between layers and on top for those Instagram-worthy cheese pulls.
Rest Before Serving: Let the mac and cheese sit for 5-10 minutes after baking to allow the sauce to thicken to the perfect consistency.

How to Serve

Baked mac and cheese works beautifully in so many meal contexts:

Main Dish Pairing:

Serve with a simple green salad dressed with vinaigrette to cut through the richness, or roasted vegetables like Brussels sprouts or broccoli for a complete meal.

Side Dish Glory:

Pairs wonderfully with grilled or roasted meats—think BBQ ribs, rotisserie chicken, or a juicy steak. It’s also a holiday table must-have alongside turkey or ham.

Presentation:

Sprinkle with fresh parsley just before serving for a pop of color. Serve in individual ramekins for a special touch at dinner parties.

Make Ahead and Storage

Make Ahead

Prepare the entire dish up to the point of baking, cover tightly with foil, and refrigerate for up to 2 days. When ready to serve, let it sit at room temperature for 30 minutes, then bake as directed, adding about 10-15 extra minutes since you’re starting with a cold dish.

Storing Leftovers

Store cooled leftovers in an airtight container in the refrigerator for up to 4 days. The sauce may thicken considerably when chilled.

Freezing

For longer storage, freeze the unbaked mac and cheese without the breadcrumb topping for up to 3 months. Thaw overnight in the refrigerator, add the topping fresh, and bake as directed with extra time.

Reheating

Reheat individual portions in the microwave with a splash of milk to restore creaminess. For larger amounts, cover with foil and reheat in a 325°F oven until hot throughout (about 20 minutes). Remove the foil for the last few minutes to re-crisp the topping.
