Easy Macaroni And Cheese Recipe No Flour: Velvety Smooth Without The Roux

Making creamy macaroni and cheese without flour is simpler than you think. This method uses a no-fuss technique that delivers velvety smooth results every time.

By using evaporated milk and a touch of cornstarch, you can create a rich, luscious sauce that clings perfectly to the pasta. It’s the easy way to enjoy classic comfort food.

The cheese blend is everything here. Sharp cheddar from a block melts smoother than pre-shredded (which has anti-caking agents). I grab mine from Whole Foods or Trader Joe’s—both have great cheddar options. American cheese might seem old-school, but it’s the secret to ultra-creamy sauce. Look for deli counter slices rather than the pre-packaged kind for better melt.

No evaporated milk? Whole milk plus a splash of cream works in a pinch (use 1.75 cups milk + 0.25 cup cream). Swap cheddar for Gruyère or Monterey Jack—both melt beautifully. Cornstarch is key for thickening without flour, but arrowroot powder at the same amount does the job too. The mustard adds tang—yellow mustard works fine if you’re out of Dijon.

Sauce thickens as it cools. Leftovers keep 4-5 days in the fridge, but add a splash of milk when reheating. Freezes well for up to 3 months—portion before freezing for easy meals. Cooked pasta absorbs liquid, so expect it to tighten up overnight.

Step-by-Step Instructions for Macaroni And Cheese Without Flour

Here’s the method. Simple, straightforward, and it works every time.

Step 1: Cook the Pasta Al Dente

Bring a large pot of salted water to a rolling boil. Add the 12 oz Elbow Macaroni and cook according to package directions for al dente, about 1 minute less than suggested. You want it firm because it’ll continue cooking when you add the sauce.

Drain the pasta in a colander but don’t rinse it. That light starch coating actually helps the sauce cling better. Shake the colander gently to remove excess water, then set it aside. The pasta should be tender with a slight bite, not mushy.

Step 2: Create the Cornstarch Slurry

In a small bowl, whisk together the 1 tbsp Cornstarch with 2 tbsp of the 2 cups Evaporated Milk until completely smooth. This slurry will thicken the sauce without needing a roux. It’s the secret to that velvety texture.

Set this mixture aside while you melt the butter. The key here is ensuring no lumps remain—whisk vigorously until it looks like thin, creamy liquid. This step prevents clumping when you add it to the hot mixture later.

Step 3: Build the Cheese Sauce Base

In a large saucepan, melt the 3 tbsp Unsalted Butter over medium heat. Once melted, pour in the remaining evaporated milk and the cornstarch slurry. Stir constantly with a wooden spoon for 2-3 minutes until the mixture thickens slightly and coats the back of the spoon.

Add the 1 tsp Dijon Mustard, 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, 0.5 tsp Kosher Salt, and 0.25 tsp Ground Black Pepper. Stir to combine. The mustard adds a subtle tang that cuts through the richness of the cheese, while the garlic and onion powders deepen the flavor.

Step 4: Melt in the Cheeses

Reduce the heat to low and begin adding the cheese, a handful at a time. Start with the 2.5 cups Sharp Cheddar Cheese, stirring constantly until each addition is fully melted before adding more. This gradual process ensures a smooth, lump-free sauce.

Once the cheddar is fully incorporated, add the 4 oz American Cheese. The American cheese contains sodium citrate, which helps emulsify the sauce and gives it that ultra-creamy, stable texture. Stir until completely melted and silky.

Step 5: Combine and Adjust Consistency

Add the cooked elbow macaroni to the sauce and stir until every piece is evenly coated. If the sauce seems too thick, stir in the 0.5 cup Whole Milk, a little at a time, until it reaches your desired creaminess. The pasta will absorb some of the sauce as it sits, so err on the side of slightly thinner.

Taste and adjust the seasoning if needed. The sauce should cling to the pasta but still flow easily. Serve immediately while hot, as the sauce will continue to thicken as it cools. This is comfort food at its finest—rich, creamy, and effortlessly smooth.

Flavor Customization for This Dish

Add a Kick

For a spicy twist, stir in ½ tsp cayenne pepper or 1 tbsp hot sauce into the finished sauce. I love adding diced jalapeños for fresh heat. The capsaicin balances the richness beautifully.

Herb Infusion

Fresh herbs elevate this dish. Try 1 tbsp chopped chives or 1 tsp dried thyme. Stir in at the end to preserve their aroma. I often use flat-leaf parsley for a pop of color.

Protein Boost

Add cooked proteins for a heartier meal. 1 cup cooked bacon, diced ham, or rotisserie chicken work great. Stir in after the sauce is complete to maintain creaminess.

Veggie Addition

Sneak in vegetables for extra nutrition. 1 cup steamed broccoli or sautéed mushrooms blend perfectly. Fold in gently to avoid breaking the pasta. 💛

Crunchy Topping

Top with ½ cup breadcrumbs mixed with 2 tbsp melted butter. Broil for 2-3 minutes until golden. This adds a satisfying texture contrast to the creamy base.

Cheese Swap

Experiment with different cheeses. Pepper Jack adds heat, while Gruyère offers nutty depth. Use the same total amount for best results. The melt quality varies, so shred yourself.
