Ingredients for barilla gluten free mac and cheese
Sixteen ingredients transform into a velvety gluten-free masterpiece—creamy sauce meets sturdy pasta in one pot.
| Ingredient | Amount | Notes |
|---|---|---|
| Barilla Gluten-Free Pasta 🍝 | 12 oz | Penne or elbow shape preferred |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for roux |
| All-Purpose Gluten-Free Flour Blend 🌾 | ½ cup | Bob's Red Mill 1:1 preferred |
| Sharp White Cheddar Cheese 🧀 | 2 cups | Shredded, block preferred |
| Gruyère Cheese 🧀 | 1 cup | Shredded, aged 12+ months |
| Cream Cheese 🧀 | 8 oz | Full-fat, room temperature |
| Whole Milk 🥛 | 2 cups | Warm for best emulsification |
| Yellow Onion 🧅 | 1 whole | Diced, sweet variety |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Coarsely ground |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For finishing drizzle |
| Nutritional Yeast 🌿 | 2 tbsp | For umami depth |
| Dried Mustard Powder 🌶️ | ½ tsp | For subtle tang |
The cheese selection is non-negotiable for that signature depth. Gruyère adds nutty complexity while sharp white cheddar delivers the classic tang—skip pre-shredded (it contains anti-caking agents that make the sauce grainy). For the flour, Bob's Red Mill 1:1 blend is the gold standard, but King Arthur works too. The Barilla pasta must be gluten-free—regular pasta won't hold up in the creamy sauce. Costco carries both the pasta and cheese in bulk, saving you money for multiple batches. Pro tip: Keep your cheeses in their original wax paper, sealed in a bag with a silica packet for maximum freshness.
No Gruyère? Parmesan at half the amount gives a similar umami punch, though it lacks the melt. Substituting dairy-free cheese? Miyoko's or Violife brands work best for texture, but expect a slightly different flavor profile. The mustard powder can be swapped for Dijon mustard (use half the amount), and if you're avoiding gluten entirely, verify your flour blend is certified. Diamond Crystal kosher salt is crucial—it dissolves perfectly and doesn't leave grainy residue. For the roux, don't rush the cooking time—this is where the magic happens. If you're adding crispy bacon or roasted veggies, do it in the last 2 minutes to maintain that perfect sauce consistency.
This reheats beautifully—just add a splash of milk and stir over low heat. Keeps for 4-5 days in the fridge, though I rarely have leftovers that long. For meal prep, portion into individual containers with a drizzle of olive oil on top to prevent drying. Freezes for 3 months if you want to make a big batch ahead of time. The sauce thickens as it cools, so don't over-stir when reheating—just let it warm through and stir gently at the end. For extra indulgence, top with crispy fried shallots or a sprinkle of smoked paprika before serving.

Step-by-step instructions for Barilla gluten-free mac and cheese
This one-pot method delivers restaurant-quality texture without gluten cross-contamination.
🍳 Step 1: Build the Cheese Roux for Ultra-Creamy Sauce
Melt the 0.75 cup unsalted butter in a large, heavy-bottomed pot over medium-low heat. Once fully melted, whisk in the 0.5 cup all-purpose gluten-free flour blend immediately—this prevents lumps. Cook for 2-3 minutes until the mixture turns a pale golden color and smells nutty. This roux forms the velvety base of our sauce.
Here's the thing—don't rush this step. If the roux darkens to tan or brown, you'll taste bitterness. Remove from heat if needed and let it cool slightly before proceeding. The perfect roux should coat the back of a spoon smoothly without graininess.
👨🍳 Step 2: Sauté Aromatics and Add Milk Gradually
Return the pot to medium heat and add the diced yellow onion and minced garlic cloves. Cook for 3-4 minutes until the onion becomes translucent and the garlic releases its aroma. You'll smell that sweet onion caramelizing—that's when you know it's ready.
Slowly pour in the 2 cups whole milk while whisking continuously to prevent lumps. Bring to a gentle simmer and cook for 5-7 minutes until slightly thickened. This gradual addition creates a silky texture without curdling. If the sauce looks too thin, simmer uncovered for another minute or two.
🥘 Step 3: Incorporate Cheeses and Mustard for Depth
Reduce heat to low and gradually add the 2 cups sharp white cheddar cheese, 1 cup gruyère cheese, and 8 oz cream cheese in batches, whisking vigorously after each addition. The sauce should thicken dramatically as the cheeses melt. If it seizes up, add 1-2 tablespoons of the reserved pasta water later.
Stir in the 2 tbsp nutritional yeast and 0.5 tsp dried mustard powder—these add umami complexity and subtle tang. The mustard powder might seem odd, but it balances the richness beautifully. Taste and adjust seasoning with the 1.5 tsp kosher salt and 0.5 tsp black pepper as needed.
🍳 Step 4: Cook the Pasta to Al Dente Perfection
Add the 12 oz Barilla gluten-free pasta to the sauce and stir gently to coat each strand. Bring to a gentle boil, then reduce heat to medium-low and simmer uncovered for 12-15 minutes, stirring occasionally. The pasta should be al dente with just a hint of bite.
Here's my pro tip: Check for doneness 2 minutes early—gluten-free pasta continues cooking after removal from heat. Drain any excess liquid if needed, but don't rinse—surface starch helps the sauce cling perfectly.
🔥 Step 5: Finish with Olive Oil for Richness
Remove from heat and stir in the 2 tbsp extra-virgin olive oil. This final touch adds luxurious mouthfeel and prevents the sauce from becoming too heavy. Let the mac and cheese rest for 5 minutes—this allows the flavors to meld completely.
Serve immediately in deep bowls, garnished with extra grated cheddar if desired. The texture should be velvety yet slightly firm, with each bite delivering that perfect cheesy pull. This one-pot method ensures no gluten cross-contamination while delivering restaurant-quality creaminess in every forkful.
Pro Tips For Making Barilla Gluten Free Mac And Cheese
- Cook Pasta Al Dente: Barilla’s gluten-free noodles cook faster than regular pasta—test one at the 1-minute mark, then drain when it’s just firm. Overcooking turns them mushy, and gluten-free pasta doesn’t bounce back like wheat pasta. (Yes, even if you’re impatient like me.)
- Melt Cheese Slowly: Skip the high-heat blitz. Warm your cheese sauce over medium-low while whisking constantly—Gruyère and sharp cheddar burn fast. If it seizes, add 1-2 tablespoons of cold milk or pasta water to smooth it out. (I learned this the hard way with grainy lumps.)
- Toast the Flour Blend: Dry-toast your gluten-free flour blend in the butter for 30 seconds before adding liquid. This removes raw flour taste and adds nutty depth—like a roux, but faster. (Sounds weird, but it works.)
- Reserve Starchy Water: Before draining the pasta, scoop out ½ cup of starchy water and fold it into the finished sauce. Gluten-free pasta needs that extra glue to hold together—no one wants a dry, crumbly mess. (Your future self will thank you.)

Frequently asked questions
Why does gluten-free pasta need special handling in creamy sauces?
Gluten-free pasta absorbs sauce differently than traditional wheat pasta. Without gluten's natural elasticity, it can become mushy when overcooked or break apart in rich sauces. The one-pot method in this recipe keeps the pasta sturdy while ensuring perfect sauce adhesion. Always cook gluten-free pasta 1-2 minutes less than package instructions and avoid rinsing—surface starch helps the sauce cling.
Can I substitute the gluten-free flour blend with cornstarch?
Not for this recipe—cornstarch creates a thinner, less creamy sauce that won't hold up to the cheeses. The gluten-free flour blend (like Bob's Red Mill 1:1) mimics all-purpose flour's structure, creating that signature velvety texture. For a roux, the protein in gluten-free flour helps emulsify the dairy better than starch alone. If you're out of flour, try a 50/50 mix of gluten-free flour and cornstarch, but expect slightly less thickness.
What's the secret to preventing a grainy cheese sauce?
The three key factors are: using block cheese (not pre-shredded), adding cheeses gradually, and keeping heat low. Pre-shredded cheese contains anti-caking agents that create graininess. Always shred your own cheddar and Gruyère, and whisk vigorously as you add each batch. If the sauce seizes, immediately add 1-2 tablespoons of pasta water to smooth it out. The low-and-slow approach prevents scorching while allowing cheeses to melt completely.
How do I make this recipe dairy-free?
Replace the butter with vegan butter or olive oil, use dairy-free milk (like oat or almond), and substitute the cheeses with Miyoko's or Violife dairy-free cheeses. For thickness, add 1 tbsp cornstarch to the roux. Note that the texture will be slightly different—dairy-free cheeses melt less dramatically, so you may need to add extra sauce or adjust seasoning. The nutritional yeast remains a great umami booster for the flavor profile.
Can I make this ahead of time for a party?
This mac and cheese actually tastes better the next day as flavors meld. For parties, prepare it 1-2 days ahead and reheat gently with a splash of milk. For serving, transfer to a baking dish, top with gluten-free breadcrumbs, and broil for 3-5 minutes to create a crispy top. Keep it warm in a slow cooker on "warm" setting if needed—just stir occasionally to prevent sticking. The one-pot method makes it perfect for crowd feeding without last-minute stress.
