Mac N Cheese Recipe No Roux: Stovetop Creaminess Without the Fuss

I’ve spent years perfecting a stovetop mac and cheese that skips the roux but still delivers that velvety texture we all crave. This method relies on a simple slurry of cornstarch and milk to create a sauce that clings to every noodle without the fuss of butter and flour.

The beauty of this approach is its simplicity—no whisking, no lumps, just a smooth cheese sauce that comes together in minutes. It’s the kind of recipe that feels indulgent but is surprisingly easy, even for beginners.

What you’ll get is a dish with perfectly cooked pasta and a creamy sauce that’s rich and comforting. The cheese melts seamlessly, creating a consistency that’s impossible to resist.

Serve it hot, straight from the pot, for a meal that’s as satisfying as it is straightforward.

Ingredients for Mac N Cheese Recipe No Roux

Short list. Big cheesy flavor. No roux, no problem.

The cheese blend is everything here. Sharp cheddar for bite, Gruyère for nutty depth (find it at Whole Foods or Trader Joe’s), and yes—American cheese (the real stuff, not singles) for that ultra-smooth melt. Shred it fresh from the block; pre-shredded has anti-caking agents that make the sauce grainy. The milk needs to be whole—lower fat won’t give you that velvety texture the intro promises.

No Gruyère? Fontina or Monterey Jack work well. Out of cornstarch? All-purpose flour at the same amount (but you’ll need to whisk it into hot milk slowly). The Dijon adds a tangy backdrop—yellow mustard in a pinch. For extra richness, stir in that optional butter at the end. Skip the hot sauce if you’re serving kids (or add it to individual bowls).

This keeps 3-4 days in the fridge, but the sauce thickens as it cools. Reheat with a splash of milk to loosen. Doesn’t freeze well—the cheese can separate. Best eaten fresh, straight from the pot like the intro says.

Step-by-Step Instructions for Mac N Cheese No Roux

This stovetop method delivers ultra-creamy results without the hassle of a roux.

Step 1: Cook the Elbow Macaroni

Bring a large pot of salted water to a boil over high heat. Add the 12 oz Elbow Macaroni and cook according to package instructions until al dente, about 8-9 minutes. You want it slightly underdone since it’ll finish cooking in the sauce.

Drain the pasta in a colander and rinse briefly with cool water to stop the cooking process. Shake off any excess water—this prevents the sauce from becoming too thin. Set the pasta aside while you prepare the cheese mixture.

Step 2: Create the Cornstarch Slurry

In a small bowl, whisk together the 3 tbsp Cornstarch with ½ cup of the 3 cups Whole Milk until completely smooth. This slurry is what thickens the sauce without a roux, so make sure there are no lumps.

In a large pot over medium heat, pour in the remaining 2½ cups Whole Milk. Stir in the 0.5 tsp Salt, 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, and 0.25 tsp Black Pepper. Heat the milk until it’s just steaming—don’t let it boil.

Step 3: Thicken the Milk and Add Cheeses

Slowly pour the cornstarch slurry into the warm milk while whisking constantly. Continue whisking for 2-3 minutes until the mixture thickens to the consistency of heavy cream. You’ll notice it coats the back of a spoon when it’s ready.

Reduce the heat to low and add the 3 cups Sharp Cheddar Cheese, 1 cup Gruyère Cheese, and 4 oz American Cheese a handful at a time, stirring until each addition is fully melted before adding more. This gradual melting prevents clumping. Stir in the 2 tbsp Unsalted Butter, 1 tsp Dijon Mustard, and 0.5 tsp Hot Sauce for extra depth of flavor.

Step 4: Combine Pasta and Sauce

Add the cooked Elbow Macaroni to the cheese sauce and stir until every piece is evenly coated. If the sauce seems too thick, add a splash of milk, 1 tablespoon at a time, until it reaches your desired creaminess.

Let the mac and cheese sit for 2-3 minutes off the heat. This resting time allows the sauce to thicken slightly as it cools. The pasta should be tender, and the sauce should cling beautifully to every bite.

Serve immediately while hot and creamy. If it thickens too much as it cools, just stir in a little extra milk to loosen it up.
