Ingredients for Fat Free Mac and Cheese
Simple pantry ingredients create this rich, velvety dish everyone will love.
| Ingredient | Amount | Notes |
|---|---|---|
| Whole Wheat Elbow Macaroni 🍝 | 12 oz | Or regular elbow macaroni |
| All-Purpose Flour 🌾 | 3 tbsp | For thickening the roux |
| Non-Fat Milk 🥛 | 2 ½ cups | Skimmilk works perfectly |
| Low-Fat Sharp Cheddar Cheese 🧀 | 8 oz | Freshly shredded for best melt |
| Low-Fat Monterey Jack Cheese 🧀 | 4 oz | Shredded, adds creaminess |
| Dijon Mustard 🟡 | 1 tbsp | For tangy depth of flavor |
| Garlic Powder 🧄 | ½ tsp | Enhances cheese flavor |
| Onion Powder 🧅 | ½ tsp | Adds savory base note |
| Salt 🧂 | ½ tsp | Adjust to taste |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Dry Mustard 🟡 | ½ tsp | Boosts cheesy flavor |
| Nutritional Yeast 🌿 | 2 tbsp | For cheesy umami depth |
The cheese is everything here. Sargento or Kraft low-fat blocks shred beautifully—skip pre-shredded (it has anti-caking agents that make the sauce grainy). Whole wheat pasta adds fiber, but regular elbow macaroni works just as well. I grab my dairy from Whole Foods or Trader Joe’s for quality without the guilt. Non-fat milk is key—higher fat versions won’t give you that silky texture the recipe promises.
No low-fat cheese? Regular cheddar at half the amount still works (drain some fat if it separates). Swap Monterey Jack for Colby or pepper jack for variety. Out of Dijon? Yellow mustard at the same amount gets you close. The nutritional yeast is optional but adds that extra cheesy punch—find it in the bulk bins at Whole Foods or health food stores. Fresh garlic instead of powder? Use 2 cloves minced.
Leftover mac and cheese thickens as it cools. Stir in a splash of warm milk to loosen before reheating. Keeps well in the fridge for 4-5 days, freezes for 3 months (thaw overnight before reheating). I always make a double batch—perfect for quick lunches or busy weeknights.

Step-by-Step Instructions for Fat Free Mac and Cheese
This method delivers creamy, rich results while keeping things light and simple.
Step 1: Cook the Macaroni to Al Dente Perfection
Bring a large pot of salted water to a rolling boil. Add the 12 oz whole wheat elbow macaroni and cook for 8-9 minutes, stirring occasionally, until it’s just shy of tender. You want it slightly underdone because it’ll finish cooking when you combine it with the hot cheese sauce later.
Drain the pasta in a colander but don’t rinse it. Rinsing washes away the starch that helps the sauce cling to the noodles. Shake the colander gently to remove excess water, then set the macaroni aside while you make the sauce.
Step 2: Make a Smooth, Flavorful Roux
In a large saucepan, whisk the 3 tbsp all-purpose flour into the 2.5 cups non-fat milk until completely smooth. Place the pan over medium heat and cook, stirring constantly, until the mixture thickens enough to coat the back of a spoon, about 5-7 minutes.
Pay attention to the edges of the pan—when you see tiny bubbles forming there, you know it’s heating properly. Don’t let it come to a full boil, or the milk might curdle. The mixture should look like a thick, creamy soup when it’s ready for the next step.
Step 3: Build the Cheese Sauce with Bold Flavors
Reduce the heat to low and stir in the 8 oz low-fat sharp cheddar cheese, 4 oz low-fat monterey jack cheese, 1 tbsp dijon mustard, 0.5 tsp garlic powder, 0.5 tsp onion powder, 0.5 tsp salt, 0.25 tsp black pepper, 0.5 tsp dry mustard, and 2 tbsp nutritional yeast.
Stir continuously until all the cheese is melted and the sauce is smooth. This is where the magic happens—the nutritional yeast and dry mustard amplify the cheesy flavor, while the dijon mustard adds a subtle tang. Taste and adjust seasoning if needed, remembering that the flavors will intensify slightly as it thickens.
Step 4: Combine and Finish for the Perfect Texture
Add the cooked macaroni to the cheese sauce and stir gently but thoroughly to coat every noodle. If the sauce seems too thick, add a splash of warm water or milk, 1 tablespoon at a time, until it reaches your desired consistency.
Let the mixture sit for 2-3 minutes off the heat. This gives the pasta time to absorb some of the sauce and soften any bits that might have firmed up during draining. The sauce should be creamy and cling beautifully to the macaroni, with no graininess or separation.
Pro Tips For Making Fat Free Mac And Cheese
- Cook the Roux Longer: After burning two sauces, I learned to cook the flour and milk mixture for a full 3-4 minutes—this removes the raw flour taste and thickens it properly.
- Grate Your Own Cheese: Skip the pre-shredded stuff; freshly grated low-fat cheddar and Monterey Jack melt smoother and avoid the anti-caking agents that make the sauce grainy.
- Temper the Cheese: I used to dump cold cheese straight in and ended up with a clumpy mess—always stir in the shredded cheese off the heat, one handful at a time, to prevent breaking.
- Use Pasta Water: Sounds weird, but it works: reserve 1/2 cup of the starchy pasta water to thin the sauce if it gets too thick—whole wheat macaroni needs that extra help to stay creamy.
Best Sauces and Condiments for fat free mac and cheese
Hot Sauce Kick
Add 1-2 tsp of Frank’s RedHot to your bowl for a spicy contrast that cuts through the creamy richness. The vinegar tang complements the cheesy depth beautifully. I love how it wakes up the flavors without overwhelming the dish. 🔥
Herb Freshness
Stir in 1 tbsp fresh chives or parsley right before serving for a bright, fresh finish. This adds color and a subtle herbal note that balances the richness. Fresh herbs make all the difference in presentation too.
Acidic Brightness
A squeeze of lemon juice or a dash of apple cider vinegar brightens the dish wonderfully. Start with ½ tsp and adjust to taste. This simple addition enhances all the flavors without adding any fat. 💡
Smoky Depth
For BBQ lovers, stir in 1 tbsp sugar-free BBQ sauce per serving. The smoky-sweet contrast pairs surprisingly well with the sharp cheddar. I prefer Stubb’s for its balanced flavor that doesn’t overpower.
Garlic Bread Crumbs
Top with 2 tbsp whole wheat panko toasted with ½ tsp garlic powder for crunch. This adds texture without compromising the fat-free promise. Toast in a dry pan over medium heat for 2-3 minutes.
Salsa Fresca
Mix in ¼ cup fresh pico de gallo for a Mexican-inspired twist. The tomatoes and onions add freshness that lightens the dish. I make mine with extra lime juice for that perfect zing.

Frequently Asked Questions
Can I use regular milk instead of non-fat?
Stick with non-fat for the best texture. Whole or 2% milk can make the sauce too heavy or greasy. Non-fat creates that perfect silky consistency the recipe promises.
Why does my sauce turn out grainy?
Graininess usually means the cheese wasn’t melted slowly enough. Use low heat and stir constantly. Also, avoid pre-shredded cheese as it contains anti-caking agents that prevent smooth melting.
How can I add protein without fat?
Stir in cooked chickpeas or shredded chicken breast at the end. Both add protein while keeping the dish fat-free. 1 cup of either works well for 4 servings.
