This version delivers all the comfort of traditional mac and cheese with a fraction of the fat. A simple swap of whole milk for skim and smart thickening techniques create that signature creamy texture.
You’ll achieve rich flavor without heavy cream or excess cheese. The result is a lighter dish that doesn’t compromise on the velvety sauce or satisfying comfort we all crave.
Ingredients for Low Fat Mac N Cheese
Lighter ingredients deliver that creamy comfort you know and love.
| Ingredient | Amount | Notes |
|---|---|---|
| Whole Wheat Elbow Macaroni 🍝 | 12 oz | Or regular elbow macaroni |
| Skimmilk 🥛 | 2 cups | Cold, for roux consistency |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening the sauce |
| Butter 🧈 | 1 tbsp | Unsalted preferred |
| Sharp Cheddar Cheese 🧀 | 8 oz | Reduced-fat, block form |
| Low-Fat Mozzarella Cheese 🧀 | 4 oz | Shredded from block |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated for intensity |
| Dijon Mustard 🟡 | 1 tsp | Adds tang without fat |
| Garlic Powder 🧄 | ½ tsp | Fresh minced works too |
| Onion Powder 🧅 | ½ tsp | Enhances cheese flavor |
| Dry Mustard 🟡 | ½ tsp | Boosts cheesy depth |
| Salt 🧂 | ½ tsp | Adjust to taste |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Cayenne Pepper 🔥 | 0.125 tsp | Optional, for heat |
The cheese selection is key here. Cabot and Sargento make excellent reduced-fat cheddar blocks that melt smoothly. Always buy block cheese and shred it yourself—pre-shredded has anti-caking agents that mess with the sauce texture. For the Parmesan, Parmigiano-Reggiano is worth the splurge, but any good quality wedge works. The skim milk needs to be cold when you start the roux (trust me on this).
No skim milk? 1% or 2% milk work fine but trim the fat savings. Swap in Greek yogurt at half the amount for extra creaminess if you’re okay with a slight tang. Mustard lovers can use whole grain mustard instead of Dijon. The whole wheat pasta adds fiber, but regular elbow macaroni works too (just don’t overcook it).
Leftovers keep for 4-5 days in the fridge—reheat with a splash of milk to restore creaminess. Freezes for 3 months if you portion before freezing. The sauce thickens as it cools, so thin with warm milk when reheating (worth the extra minute).

Instructions
Here’s the method. Straightforward, tested, works every time.
Step 1: Cook the Macaroni to Al Dente
Bring a large pot of salted water to a rolling boil. Add the 12 oz Whole Wheat Elbow Macaroni and cook according to package directions for al dente texture, usually 8-9 minutes. You want it slightly firm when bitten, as it will continue cooking when combined with the hot cheese sauce.
Stir occasionally to prevent sticking, and check the pasta a minute before the suggested cook time. Drain the pasta in a colander and rinse briefly under cold water to stop the cooking process. This also removes excess starch that could make the final dish gummy.
Step 2: Prepare the Low-Fat Roux
In a large saucepan over medium heat, melt the 1 tbsp Butter. Once melted and foaming, whisk in the 2 tbsp All-Purpose Flour to form a smooth paste. Cook for 1-2 minutes, stirring constantly, until the mixture turns a light golden color and smells slightly nutty.
This roux will thicken the sauce without adding excess fat. The key is to cook it just enough to remove the raw flour taste but not so long that it darkens, which would make the sauce too rich for this lighter version.
Step 3: Create the Creamy Cheese Sauce
Gradually whisk in the 2 cups Skimmilk, adding it in a slow, steady stream to prevent lumps. Continue whisking until the mixture is smooth. Cook over medium heat for 3-4 minutes, stirring frequently, until the sauce thickens enough to coat the back of a spoon.
Reduce the heat to low, then stir in the 1 tsp Dijon Mustard, 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, 0.5 tsp Dry Mustard, 0.5 tsp Salt, 0.25 tsp Black Pepper, and 0.125 tsp Cayenne Pepper. These seasonings enhance the cheese flavors and balance the dish perfectly.
Next, add the shredded 8 oz Sharp Cheddar Cheese and 4 oz Low-Fat Mozzarella Cheese, stirring constantly until fully melted and smooth. Finally, stir in the 0.5 cup Parmesan Cheese until the sauce is velvety and lump-free.
Step 4: Combine and Serve
Add the cooked and drained macaroni to the saucepan with the cheese sauce. Stir gently to coat every piece evenly. If the sauce seems too thick, add a splash of the reserved pasta water to loosen it to your desired consistency.
Let the mixture sit for 2-3 minutes off the heat to allow the flavors to meld together. The pasta will absorb some of the sauce, creating a perfectly creamy texture. Serve immediately while hot, as the sauce will thicken further as it cools.
Pro Tips For Making Low Fat Mac N Cheese
- Use Cold Skim Milk: Start with cold skim milk to prevent the flour from clumping when you whisk it in—I learned this after ending up with lumpy cheese sauce more times than I care to admit.
- Grate Your Own Cheese: Skip the pre-shredded sharp cheddar; it’s coated in anti-caking agents that make the sauce grainy. Grate it fresh for a smoother, creamier texture.
- Cook Pasta Al Dente: Whole wheat elbow macaroni can turn mushy fast, so pull it off the heat 1 minute early—it’ll finish cooking in the cheese sauce.
- Bloom the Flour: After melting the butter, cook the flour for 1-2 minutes before adding milk to remove the raw taste. It’s a small step that actually changes the outcome.
Essential Equipment for low fat mac n cheese
Quality Saucepan
A heavy-bottomed 3-quart saucepan is essential for even heat distribution. I use my All-Clad Stainless Steel—it prevents hot spots that could scorch the milk. Nonstick works too, but stainless is more durable for cheese sauces.
Whisk for Smoothness
A flat-bottom whisk helps create a lump-free roux and sauce. The flat edges get into the pan corners better than balloon whisks. I keep a 10-inch whisk dedicated just for sauces—makes cleanup easier. 💡
Cheese Grater
Block cheese melts better than pre-shredded, so a box grater is your best friend here. I love my OXO Good Grips grater—it has multiple blade sizes and a non-slip base. Grate the cheese fresh for the smoothest sauce.
Large Pasta Pot
The pasta needs room to move while cooking, so use a 5-6 quart pot. I prefer enamel-coated cast iron like Le Creuset for even heating. Don’t skimp on size or you’ll end up with gummy macaroni.
Instant-Read Thermometer
For perfect al dente pasta every time, I check with my ThermoWorks ThermoPop. Pull the pasta at 145°F internal temp—it’ll finish cooking in the hot sauce. This little tool takes the guesswork out completely.
Wooden Spoon
A wooden spoon is ideal for stirring the cheese sauce as it thickens. It won’t scratch your pan like metal utensils might. I’ve had my olive wood spoon for 10 years—it’s my go-to for all creamy dishes. 🔥

Frequently Asked Questions
Can I use regular milk instead of skim?
Yes, but it will increase the fat content. 1% or 2% milk works well while keeping it relatively light. The sauce may be slightly richer with whole milk.
Why does the sauce get too thick?
Overcooking the roux can make the sauce too dense. Keep it at medium heat and whisk constantly. Thin with reserved pasta water if needed.
Can I add vegetables to this dish?
Try steamed broccoli or sautéed spinach for extra nutrition. Stir them in during the final step for even heating.
How can I make it even creamier?
Add 1/4 cup Greek yogurt at the end for extra richness without much fat. Stir gently to avoid curdling.
