This gut-friendly mac and cheese uses gluten-free pasta and a smooth béchamel made from lactose-free milk and FODMAP-safe cheese. Dijon mustard and vinegar add a subtle tang, while a crispy rice topping gives it the perfect crunch. You can serve it creamy straight from the pot or bake it for a bubbly, golden finish. It’s family-friendly, easy to prep, and gentle on IBS-sensitive stomachs.

How To Make Low FODMAP Mac and Cheese:
Prep Ingredients:
Grate your cheeses and measure all ingredients. Set aside.
Cook Pasta:
Boil a large pot of salted water. Add pasta and cook 2–3 minutes less than package directions. Reserve some pasta water. Preheat oven to 180°C (356°F) if baking.
Make the Béchamel Sauce:
Melt butter in a large pot over medium heat. Whisk in cornstarch. Cook for 1 minute, then slowly add milk while whisking. Simmer on low heat for 5–15 minutes until thick and smooth.
Add Cheese and Flavor:
Remove sauce from heat. Gradually stir in cheeses until melted. Add vinegar, mustard, and salt to taste.
Combine with Pasta:
Mix cooked pasta into the sauce. Add pasta water to loosen if needed. Serve creamy, or move to baking.
Bake (Optional):
Top with crushed rice bubbles for crunch. Bake for 20–30 minutes until golden. For a browned top, grill briefly at the end. Drizzle with truffle or garlic-infused oil if desired.

- Use only gluten-free pasta and cornstarch.
- Grate cheese fresh—pre-shredded often contains additives.
