Gluten-Free Mac and Cheese
Ingredients
Method
- Cook the pasta. Bring a large pot of well-salted water to a boil. Cook gluten-free pasta according to package directions until al dente — watch carefully as GF pasta can go from perfect to mushy quickly. Reserve 1/2 cup pasta water, then drain.
- Make the roux. In a large saucepan over medium heat, melt the butter. Add cornstarch and whisk constantly for 1–2 minutes until a smooth paste forms.
- Build the sauce. Slowly pour in the warmed milk, whisking constantly to prevent lumps. Continue whisking over medium heat for 4–5 minutes until the sauce thickens enough to coat the back of a spoon.
- Add the cheese. Remove from heat and stir in cheddar, Gruyère, and Parmesan a handful at a time, letting each addition melt fully before adding more. Stir in Dijon mustard, garlic powder, smoked paprika, salt, and pepper.
- Combine and serve. Add the drained pasta to the cheese sauce and stir well to coat. If the sauce is too thick, add reserved pasta water a tablespoon at a time. Serve immediately.

The Key to Great Gluten-Free Mac and Cheese
Making mac and cheese without wheat flour comes down to two things: the right thickener and the right pasta.
For the roux: We swap all-purpose flour for cornstarch (or arrowroot powder), which creates an equally smooth, stable sauce with no grainy texture or starchy taste.
For the pasta: Brown rice pasta holds its shape best and has a mild flavor that lets the cheese shine. Chickpea pasta adds a protein boost and a slightly nutty flavor that works beautifully here.
Critical tip: Always grate your cheese fresh from a block. Pre-shredded cheeses contain anti-caking agents that prevent smooth melting and make your sauce grainy.
Ingredients
(Full recipe card with measurements is below)
- Gluten-free elbow macaroni — brown rice or chickpea pasta both work wonderfully.
- Unsalted butter — the fat base for your roux.
- Cornstarch — the GF thickener that makes a flawlessly smooth sauce.
- Whole milk — warmed before adding to prevent lumps.
- Sharp cheddar — the bold, classic flavor backbone.
- Gruyère — adds nutty, slightly sweet depth.
- Parmesan — brings savory, salty intensity. Freshly grated only!
- Dijon mustard — amplifies the cheesy flavor without being detectable.
- Garlic powder + smoked paprika — warm, savory background notes.
How to Make Gluten-Free Mac and Cheese
Step 1: Cook the Pasta
Bring a large pot of heavily salted water to a boil. Cook your gluten-free pasta according to package directions until just al dente — watch it carefully. Gluten-free pasta has a narrower window between perfectly cooked and mushy, so start checking a minute or two early. Reserve about 1/2 cup of pasta water before draining.
Step 2: Make the Cornstarch Roux
In a large saucepan over medium heat, melt the butter. Add cornstarch and whisk constantly for 1–2 minutes until a smooth, thick paste forms. You’re cooking out the raw starch flavor, just like with a flour roux.
Step 3: Build the Sauce
Slowly pour in the warmed milk, whisking constantly to prevent any lumps. Keep whisking over medium heat for 4–5 minutes until the sauce thickens enough to coat the back of a spoon.
Step 4: Add the Cheese
Remove the pan from heat. Add the grated cheddar, Gruyère, and Parmesan a handful at a time, stirring until each addition is fully melted before adding the next. Stir in Dijon mustard, garlic powder, smoked paprika, salt, and pepper.
Step 5: Combine and Serve
Add the drained pasta directly into the sauce and fold everything together. If the sauce feels too thick, add the reserved pasta water a tablespoon at a time. Taste, adjust seasoning, and serve immediately.
Tips, Variations & Add-Ins
Add a crunchy topping: Transfer to a baking dish, top with GF breadcrumbs tossed in olive oil, and broil for 3–4 minutes for a golden, crispy crust.
Make it spicy: Stir in a teaspoon of hot sauce or a pinch of cayenne. For a full spicy mac experience, our Spicy Mac and Cheese is packed with heat-building tips.
Try a dairy-free twist: If you need both gluten-free and dairy-free, our Vegan Mac and Cheese uses a silky cashew sauce that’s completely plant-based.

Storing & Reheating
- Refrigerator: Store in an airtight container for up to 4 days.
- Reheating: Warm on the stovetop over low heat, adding a splash of milk and stirring frequently. The microwave works too — heat in 30-second bursts, stirring between each.
- Freezing: The cheese sauce freezes well, but GF pasta can become mushy after freezing. Freeze the sauce separately and cook fresh pasta when ready to serve.
Frequently Asked Questions
What’s the best gluten-free pasta for mac and cheese?
Brown rice pasta is our top pick — it holds its shape well and has a neutral flavor. Chickpea pasta is a close second and adds extra protein. Avoid lentil or green pea pasta, which have stronger flavors that can clash with the cheese sauce.
Why does my cheese sauce turn grainy?
Two common culprits: adding cheese over high heat (causes the proteins to seize) or using pre-shredded cheese (contains starches that prevent smooth melting). Remove the pan from heat before stirring in cheese, and always grate fresh from a block.
Is this recipe celiac-safe?
The recipe itself uses no gluten-containing ingredients. If you have celiac disease, check that your GF pasta, butter, mustard, and all other packaged ingredients are certified gluten-free and manufactured in dedicated gluten-free facilities.
